1. The quality of rubber According to the performance of rubber roller in printing, the quality of rubber is fundamental to the function and influence of printing rubber roller in printing. It can mainly control the following expressions of rubber roller in printing. N can separate ink in the form of uniform ink film, N ensure smooth ink transfer N forming ink accumulation to make up the inconsistency of ink caused by printing and conveying N compensation geometric difference 3 N compensation and suppression of vibration N control hot growth N's chemical compatibility to the press on the printer mainly includes: ink, moistening plate, cleaning and maintaining chemical. N anti ozonation, aging, stable hardnes. N good thermal and electrical conductivity N good resiliency and resilience N Resistance to wear and tear 2. The surface structure of the rubber roller The surface roughness of rubber roller is very important technical indexes, it controls the performance of roller transfer ink and fountain solution. In general, the quality standard of surface roughness can be: roller surface roughness of 6 to 20 microns, and the surface roughness of the alcohol water roll is 4 to 10 microns, and some printing in order to increase the ability of water machine, water surface grinding roller more detailed, such as: the surface of alcohol dampening water roll in KOMORI presses on the roughness of 2 to 6 microns. The surface roughness of roll in printing should pass the accurate measurement of the water and ink, to ensure the stability of water and ink, so as to ensure the stability of color printing, at the same time, the ink ink film to form uniform separation, ensure smooth

Commissioning and application of rubber roller for printing presses Printing practitioners know that the height of the letterpress is 3.14mm, and the height of the type is the same, and the PS version of the relatively low 1.2mm, so in the installation and commissioning rubber roller must be aware of.If it is printed with an undertone, the rubber roller can be adjusted lower, error for ±0.5mm, so that the ink roller pass to the printing rubber roller ink more evenly, and the printing rubber roller reflected in the printing plate on the same effect, printed products to make people pleasing, if not so, there will be ink, Monlchamus road and other phenomena. In the printing text, the height of rubber roller and text version of the flat or slightly lower, so that the printing rubberroller gently rub plates, so that the text printing is very clear, clean, cots wear surface is not easy to damage, can extend the use of the printing plate.(Y7 S6 T.U ~% M3 I9 o0 X Adjustment should be used when adjusting cots.Before using the printing plate out so that the level of the adjustment roller to pull out several times, the ink size of the adjustment roller immediately displayed, the operator can be based on the different needs of printing to determine the level of the printing cots, and then the top wire rope.This will not change the height of cots in high speed printing. If we are in the use of rubber roller lack of patience, debugging the haste to save trouble, the following conditions will occur: (A) The surface of the roller appears damaged, slag, so that the text printing is missing pen, the text is ambiguous, and even appear paste blind, slip gum phenomenon. (B) The wording is different, and even the appearance of the printed surface only text marks but no ink color. (C) If the cots are adjusted to the rubber rollers too tight, the printing cots will be twisted to cause economic losses and equipment accidents. From: China Roll Industry Network

1. Ink roller Ink roller refers to all the cots in the ink supply system. The function of the ink roller is to deliver the printing ink to the printing plate in a quantitative and uniform manner. Ink roller can be divided into three categories: ink carrying, ink transferring and plate relying. Ink carrying roller is also called ink bucket roller. It is used to extract quantitative ink from ink bucket each time and then transfer it to ink transferring roller (also called uniform ink roller). The ink transfer roller receives these inks and evenly distributes them to form a uniform ink film, which is then transferred to the plate backup roller, which is responsible for uniformly distributing the ink on the plate.So far, the task of ink roller is completed. The uniform distribution of ink is gradually completed in the successive transfer process of several cots. In this process, in addition to cots, there are hard rollers and so-called ink rollers. In offset press, cots and hard rolls are always arranged at intervals, forming a soft and hard alternate collocation, this arrangement is more conducive to the transfer and distribution of ink. The function of inking roller can further strengthen the axial distribution of ink. When working, the inking roller can rotate and move in axial direction, so it is called inking roller. 2.Dampening roller The dampening roller is the rubber roller in the water supply system, similar to the ink roller, and its function is to evenly transport water to the printing plate. Dampening rollers also include water-carrying, water-passing, and printing. At present, there are two water supply methods for water rollers, one of which is continuous water supply, which relies on the plate roller without water velvet cover, and the water supply is achieved by adjusting the speed of the water bucket roller. The early water supply method was intermittent, which relied on the plate roller covered with a water velvet cover, and the water roller oscillated to supply water. The continuous water supply method is suitable for high-speed printing, and the intermittent water supply method has been gradually replaced. 3.The structure of the rubber roller The roll core and outsourcing rubber material are different depending on the purpose. The roller core structure can be hollow or solid depending on the application. The weight of the rubber roller is generally required, it affects the counterweight of the machine, and then affects the vibration stability during operation. Most of the rubber rollers of the offset printing machine are hollow rollers, which are generally made of non-feng steel pipes, and the shaft heads on both sides are welded to the steel pipes as a whole. However, in the near future, it is also made of non-metallic materials, such as glass fiber reinforced plastics and other polymer materials, whose purpose is to reduce weight and improve operating speed and stability. For example, high-speed rotary machines have application examples. 4.The material of the glue layer The rubber layer material has almost a decisive influence on the performance and quality of the rubber roller. Different rubber materials must be selected for different use environments, such as wear resistance, heat resistance, cold resistance, acid resistance, salt resistance, water resistance and so on. There are also hardness, elasticity, color, etc., which are all put forward in response to the use environment and customer requirements.

1. The main difference of the covering machine is the size of the screw diameter, which determines the processing diameter of the rubber roller. 2 .The rubber type of the rubber roller has a great relationship with the pitch of the screw. 3 .There are two ways to encapsulate the rubber rollers, flat and inclined. 4 .The encapsulation quality of the rubber roller has a great relationship with the performance of the machine. Covering machine is mainly used for rubber roller winding forming equipment. It mainly solves the traditional quality shortcomings in the rubber roller production process, such as: rubber roller delaminating, degumming, lumps, bubbles, high labor intensity, high production cost, low output and other problems. In recent years, rubber roller winding forming equipment has been widely adopted at home and abroad. When using it, not only should pay attention to its use method, but more importantly, pay attention to its maintenance. The maintenance of the covering machine in winter is very important. The main purpose is to lubricate each part in place to prevent the corrosion of chemical rubber products and other inks under long-term working conditions. The rubber roller winding machine should be erected straight at the shaft neck, and the surface should not touch each other or other objects to avoid deformation of the rubber roller. Also pay attention to the cleaning of the mechanical equipment itself, to ensure that the work surface and other parts after work must be cleaned and wiped clean in time to achieve the characteristics of onemoisturizing, two cleaning, and three guarantees of long life. The covering machine can be used for a longer time only if it is well maintained, and it is also a performance of responsibility for safe production.

1.Precautions: For unused rubber rollers or used rubber rollers that have been discontinued, keep them in the best condition according to the following conditions. Storage place ① The room temperature is kept at 15-25°C (59-77°F), and the humidity is kept below 60%. ② Store in a dark place out of direct sunlight. (Ultraviolet rays in the sun will age the rubber roller surface) ③ Please do not store in a room with UV equipment (which emits ozone), corona discharge treatment equipment, static elimination equipment, and high-voltage power supply equipment. (These devices will crack the rubber roller and make it unusable) ④ Place in a place with little indoor air circulation. How to keep ⑤ The roller shaft of the rubber roller must be placed on the pillow during storage, and the rubber surface should not be in contact with other objects. When putting the rubber roller upright, be careful not to touch hard objects. Special reminder is that the rubber roller must not be stored directly on the ground, otherwise the surface of the rubber roller will be dented, so that the ink cannot be applied. ⑥ Do not remove the wrapping paper when storing. If the wrapping paper is damaged, please repair the wrapping paper and take care to avoid air leakage. (The rubber roller inside is eroded by air and will cause aging, making it difficult to absorb ink) ⑦ Please do not place heating appliances and heat-generating objects near the storage area of the rubber roller. (The rubber will undergo chemical changes under the influence of high heat). 2.Precautions when starting to use Control the best impression line width ① Rubber is a material with a relatively large expansion rate. As the temperature changes, the outer diameter of the rubber roller will change accordingly. For example, when the thickness of the rubber roller is relatively thick, once the indoor temperature exceeds 10°C, the outer diameter will expand by 0.3-0.5mm. ② When running at high speed (for example: 10,000 revolutions per hour, running for more than 8 hours), as the temperature of the machine rises, the temperature of the rubber roller also rises, which will reduce the hardness of the rubber and thicken its outer diameter. At this time, the embossing line of the rubber roller in contact will become wider. ③ In the initial setting, it is necessary to consider maintaining the nip line width of the rubber roller in operation within 1.3 times the optimal nip line width. Controlling the best impression line width not only involves printing quality control, but also prevents the shortening of the rubber roller's life. ④ During operation, if the width of the impression line is inappropriate, it will hinder the fluidity of the ink, increase the contact pressure between the rubber rollers, and make the surface of the rubber roller rough. ⑤ The width of the impression line on the left and right of the rubber roller must be kept uniform. If the width of the impression line is set incorrectly, it will cause the bearing to heat up and the outer diameter will become thicker. ⑥ After long-term operation, if the machine is stopped for more than 10 hours, the temperature of the rubber roller will drop and the outer diameter will return to its original size. Sometimes it becomes thinner. Therefore, when restarting operation, the width of the impression line must be checked again. ⑦ When the machine stops running and the room temperature at night drops to 5°C, the outer diameter of the rubber roller will shrink, and sometimes the width of the impression line will become zero. ⑧ If the printing workshop is relatively cold, you must be careful not to let the room temperature drop. When you go to work on the first day after the rest day, while maintaining the room temperature, let the machine idle for 10-30 minutes to allow the rubber roller to warm up before checking the width of the impression line.

The rubber roller covering machine is a processing equipment for printing rubber rollers, paper rubber rollers, textile rubber rollers, printing and dyeing rubber rollers, steel rubber rollers, etc. Mainly used for rubber roll covering forming equipment. It mainly solves the traditional quality shortcomings in the production process of rubber rollers, such as: rubber roller delaminating, degumming, lumps, bubbles, high labor intensity, high production cost, low output, etc. The rubber roller covering machine is used for winding and forming without bubbles, No blisters, high flatness, fast efficiency, and manpower saving. It is one of the ideal machines and equipment for rubber roller enterprises. Pay attention to the cleanliness of the machine and equipment itself during normal use, and ensure that the work surface and other parts of the work surface should be cleaned in time after work. Add oil, wipe clean, do one moisturizing and two clean. In the classification of the machinery industry, the rubber roller forming covering machine is regarded as a rubber forming machine. It is a mechanical equipment dedicated to the rubber roller forming during the rubber roller processing process. It provides a strong equipment guarantee for the rubber roller factory to produce and process the rubber roller. Jinan Power Roller equipment Co.,Ltd specializes in the research and development and production of this equipment. You are welcome to inquire about the rubber roller forming and winding machine equipment. 1. Rubber roller forming process Before the rubber roller is formed, it is necessary to carry out a very important link, which is the encapsulation winding. By wrapping the rubber material (rubber or polyurethane) on the surface of the processed roller core to achieve the expected design thickness and hardness, so that after the late rubber roller is formed, there is no pores, degumming, etc., all of which need to be wound on the hose Special requirements for the forming process. Every rubber roller factory is required to face this link. In the past, manual rubber coating was used, but now it can be completed by a new rubber roller automatic covering machine. 2. Rubber roller forming covering machine In the industry, the wide application of PTM series rubber roll forming and covering machine itself explains its quality and maturity. As a high-end product that has been used for a long time, domestic and foreign customers and friends still tend to choose brands with stable quality and advanced technology. Cooperate directly with manufacturers. Because the later after-sales and adjustment of the machine will last for a long time, if a new manufacturer is unable to provide perfect and lasting service. Jinan Power Roller equipment Co.,Ltd has been operating this product for more than 23 years, and has accumulated a wealth of cases and technical reserves, which can guarantee your life-long equipment maintenance support.

Regarding the use of high-temperature rubber rollers, some matters that should be paid attention to, I have done a detailed arrangement here, and I hope it can be helpful to you. 1. Packaging: After the rubber roller is ground, the surface has been treated with antifouling, and it is packed with plastic film and then packed with blankets. For long-distance transportation, it must be packed in wooden boxes. 2. Transportation: Regardless of the old and new rollers, during transportation, it is strictly forbidden to press, drop, smash, or touch sharp objects. To prevent damage to the rubber surface, deformation of the shaft core and bearing position. 3.Storage: Store in a ventilated and dry room at room temperature. Stay away from heat sources. Do not touch corrosive objects. It is forbidden to press the rubber surface heavily, and avoid the working surface as much as possible on the bearing surface, or rotate and exchange the pressure roller surface regularly. If the rubber surface is pressed in one direction for a long time, slight deformation will occur. 4.installation: (1) Carefully clean the burrs, oil stains, etc. of the installation position before installation. Check whether the shaft is bent or deformed, and install the bearing accurately to ensure that the rotation force shaft core is the same core as the rubber surface. (2).The axis of the rubber roller is parallel to the sleeve or the axis of the aluminum coil or steel sleeve. 5. Use Regulations: (1).The new roll is stored for one month after arrival. This is the maturation period and can be used only after the expiration date. (2). Before using the new roller, check whether the rubber surface is compressed, bruised or deformed. (3).For the first time use, first lightly press and turn slowly for 10-15 minutes, this is the running-in period. This is important. After the expiration of the period, the pressure will be gradually accelerated. The effect can be achieved until full load. 6. After using the rubber roller for a period of time, the surface will be scratched due to the rubber surface of the band, the edge warping, etc. In this case, if it is a little bit, it can be used after grinding the surface. If serious damage to the rubber surface has been caused, the rubber roller needs to be replaced. 7.Friendly reminder: For some types of glue, due to insufficient strength, cracks will appear during use, and lumps will appear if they continue to be used. When rotating at high speed, it can fly out in large chunks, and should be checked frequently. Once found, it needs to be replaced in time.

After the glue is vulcanized, there are always some bubbles on the surface of the sample, with different sizes. After cutting, there are also a few bubbles in the middle of the sample. Analysis of the causes of bubbles on the surface of rubber products 1. Uneven rubber mixing and irregular operators. 2. The parking of rubber films is not standardized and the environment is unsanitary. Management is not standardized. 3. The material has moisture (add some calcium oxide when mixing) 4. Insufficient vulcanization, unfamiliar looks like bubbles. 5. Insufficient vulcanization pressure. 6. There are many impurities in the vulcanizing agent, the impurities of small molecules become decomposed in advance, and the bubbles remain in the product 7. The exhaust design of the mold itself is unreasonable, and the air cannot be exhausted in time when the rubber is punched! 8. If the product is too thick, the rubber material is too small, the heat transfer of the rubber is slow, and after the surface is vulcanized, the fluidity of the rubber decreases, resulting in a shortage of materials, so air bubbles may be generated. 9. The exhaust gas was not exhausted during the vulcanization process. 10. For formulation issues, the vulcanization system should be improved. Solution: improve the vulcanization pressure and time 1. Extend vulcanization time or increase vulcanization speed. 2. Pass several times before vulcanization. 3. Exhaust more frequently during vulcanization.

To a certain extent, zinc stearate can partially replace stearic acid and zinc oxide, but stearic acid and zinc oxide in rubber cannot completely react and have their own effects. Zinc oxide and stearic acid form an activation system in the sulfur vulcanization system, and its main functions are as follows: 1. Activation vulcanization system: ZnO reacts with SA to generate zinc soap, which improves the solubility of ZnO in rubber, and interacts with accelerators to form a complex with good solubility in rubber, activates accelerators and sulfur, and improves vulcanization efficiency. 2. Increase the cross-linking density of vulcanizates: ZnO and SA form a soluble zinc salt. The zinc salt is chelated with the cross-linked bond, which protects the weak bond, causes the vulcanization to form a short cross-linked bond, adds new cross-linked bonds, and increases the cross-linking density. 3. Improve the aging resistance of vulcanized rubber: During the use of vulcanized rubber, the polysulfide bond breaks and the generated hydrogen sulfide will accelerate the aging of the rubber, but ZnO reacts with hydrogen sulfide to generate zinc sulfide, which consumes hydrogen sulfide and reduces the catalytic decomposition of hydrogen sulfide on the cross-linked network; in addition, ZnO can sew broken sulfur bonds and stabilize cross-linked bonds. 4. Different reflection mechanisms: In different vulcanization coordination systems, the mechanism of action of different vulcanization accelerators is very different. The effect of ZnO and SA reaction to form a zinc stearate intermediate is also different from that of using zinc stearate alone.

Static electricity is very common when mixing rubber, no matter the season. When the static electricity is serious, it will cause a fire and cause a production accident. Analysis of the causes of static electricity: There is strong friction between the rubber material and the roller, resulting in frictional electrification. Preventing static electricity hazards during the production of rubber products is a problem faced by many companies producing rubber products and deserves the attention of people in the industry. Measures to protect against static electricity include: 1. The air is dry, pay attention to moisturizing, especially dry in winter! 2. For equipment grounding problem, ensure normal grounding, and connect the double roller to a ground wire. 3. It has something to do with clothes and shoes. Don't wear chemical fiber clothes and insulated shoes. Static electricity is very serious. 4. It is related to human physique. When mixing rubber, don't make your hands too dry, you can moisten your hands. 5. In the operation process, as long as the tip of the cutter is used to touch the roller at any time, and to avoid direct contact between the hand and the roller, the pain of electrostatic discharge can be avoided. 6. The manual input of rubber must be light and slow. It is strictly forbidden to use insulating materials for the covering. 7. The rubber mixing equipment is equipped with an induction static eliminator. 8. In places where there is a risk of explosion or fire and to prevent the human body from being charged, the operator must wear anti-static work clothes, anti-static shoes or conductive shoes. Conductive ground should be laid in the operation area.
