We have taken the trouble to say again and again: use rubber rollers to be very standardized, regularly clean, but it still can not prevent life shortening Cots, rising maintenance costs "fate." This one has rubber roller itself quality problems, but the most important thing a great relationship with the use of a method of operating personnel. Based on past experience of many users, we analyzed the rubber roll life is not long three categories reasons. From the Select Start First, select Cots in addition to look at product quality, but there is a good service is necessary, many users choose the nearest cot illustrates this point. Roller is a very delicate thing, and most of the users' awareness of cot poorly understood, which means that users need timely and thoughtful service suppliers. If you do not receive timely after-sales support, there is no practical way to solve practical problems, so shortening the life of rubber roller can be imagined. Secondly, many users likely to commit such a mistake - too much time spent on the replacement rollers. Users mind is good: three months to replace a roller, each time with new products that can enhance the print quality. But in fact often counterproductive. Cots and press is a running process, with the use of rubber roller, you will find new problems, the next will have a better solution, in order to achieve the best stage. The constantly changing Cots get excellent print actually become shackles, each a replacement rubber roller, to be shut down, disassembly, installation and commissioning. It sounds like the installation process is not difficult to install, but it is a very important issue. Roller bearings are properly installed, generally include suitable bearings between the roll neck and tightness. Now a lot of users in order to save costs, often install their own bearings, in fact there will be some small parts between the shaft and the bearing head Cots some models, is used to maintain the dynamic balance Cots, so Cots better performance of its quality balance. If because of the rubber roller bearing problems, and affect print quality, a bit more harm than good. Cots ensure each bearing, shaft seat lubrication, installed in front of all the rubber roller, rubber roller two bearings should look and machine rubber roller bearing sleeve, frame and other lubricants. Painted again, in order to minimize friction between the rotating strike because they ran back and forth string roller formed. If you often find dampening, ink roller shaft sleeve and side seat in a very short period of time had been badly worn, had re-welding and fabrication, and the ink roller bearings are also often change frequently bad, because even after a bad roller bearings roll crusher surface, resulting in greater losses. The reason is not the main do various workpiece contact surface lubrication. Norms regulating water, ink roller pressure, is a very important step. Pressure regulators too light, easily lead to poor transfer of water transfer ink; pressure regulators too heavy, it will artificially increase the friction between the roller and the roller, the ink roller temperature fever, increased extrusion expansion between the rubber roller, chapped accelerate aging, while product quality will be affected. The operator had when changing roller, pressure roller and mistakenly hard rubber roll tune too heavy, so just getting a class, which will be the root of the new Roller cracking scrapped. In addition, the use of alcohol dampening liquid, the pressure on water roller is adjusted in particular to be careful and prevent the passive transmission and reduce its service life. More important reason for the failure and maintenance, there is a majority of the maintenance factor, namely the roller surface crystallization, calcification process, the roller surface is easy to injuries, hemp eye treatment, Cots premature chapped, aging process, these articles are It is in actual operation the user the most commonly encountered problems, if ignored these conditions, it may lead to failure of the entire process. To solve the roller surface crystallization and calcification problems, since most users use a special cream product, from the water to wash, but more time-consuming, laborious, and potentially increasing the cost of production. There is a small trick is to try after each washing, and then some citric acid water again, so that some of the calcium impurities roller surface chemical reaction to form a soluble substance to clean. Practice has proved that this method works well and save money, and effort. Cots Once scratched, it can no longer be used. The reason there are two: First, pull the plate not tight or not tight version of the clip, drag shoot at the plate often split and crack, scratch ink roller by version; the second is not timely maintenance of the ink roller, rubber leather ink roller, ink residue and other impurities, increased friction rubber roller, fever, aging, eye roller surface covered with linen, general rubber roller two more serious. Cots premature chapped, aging, the problems are many reasons, such as the ink dry excess oil, so that the ink on the rubber rollers dry heat; wash rubber roller with the inappropriate choice of cleaning agent, the cleaning time is too short , impurity roller can not be thoroughly cleaned plastic; high temperature workshop environment, bad dampening cooling system, a lot of heat generated during operation that can not be distributed in the rubber roller, poly high temperature within Roller: Roller Bearings poor performance, are strung with ink roller rotates, beat friction and extrusion. These factors will accelerate early chapped cot aging. In addition, routine maintenance is also very important, many printers attached great importance to machine maintenance, in which water, ink roller is one of the elements of its focus on maintenance. Normally, more than two Roller bearing checking whether freedom of movement, is in good condition, if loose or worn, must be promptly replaced. Scrub the surface of rubber rollers to remove ink Paper, ink residue and other impurities. Check the roller surface of the rubber is good, especially by version Cots must choose the best for skin peeling, hemp eye more rubber roller should be promptly re-polish or casting. For better or worse had the plane "walk" Some users in the choice Cots always become confused, it is cheap, or choose a good quality? In fact, hovering between the two need not choose the most suitable for them is the most effective. The reason is very simple to understand, for example, the use of imported glue roll a bit nondescript on the number of domestic machine, it may not be able to bring the excellent print quality, but there are some quality through the roller, on imports of machinery and if you use the appropriate Like to get excellent print quality, like a piece of clothes, whether good or bad quality, price level, put on the best looking, most comfortable, and that is the best. Many rubber roller manufacturers in the sales roller, rubber roller generally provide products for users free of charge, to spend some time on the machine, it is good or bad, can immediately clear. We can say that longevity Cots, although at first glance appears to be quality problems, but more of a maintenance issue. The users in the face of various rubber roller, should have their own opinion, the best choice set of products.
