Rubber roller UV printing new perspective and advantages

Rubber roller UV printing using a new perspective and advantages

    In rubber roller on the UV printing and the selection of cleaning agents, etc, should pay attention to comprehensive benefits, comprehensive and to reduce costs, improve the quality of the UV printing, improve enterprise competitiveness.

    Properly installed new rubber roller bearings. The end of the first to put the new rubber roller clean of impurities, and then choose the type, model all comply with the design requirements of bearing, the grease in various mating surfaces, right, hard knocks bearing casing, evenly until bearing installed. Avoid by all means is applying pressure on bearing directly, casual, to prevent the damage of bearing before unused.

   To ensure that the rubber roller bearing, axis lubrication. In front of the plastic roller machine, rubber roller bearing both ends to the appearance and the rubber roller bearing cover, support with grease besmear again, minimize for back and forth ink roller chain formed by rotating, impact, friction, reduce the rubber roller and shaft seat on both sides of the wear and tear.

    Is widely used in recent years, UV printing, and the UV printing and ordinary two ink roller. The installation of UV and ordinary ink roller, as follows.

   1. New ink roller to adapt to the program

   debugging

    To accurately determine the position of the rubber roller on the UV printing machine suitable, regulate water roller, ink roller pressure. Rubber roller position right or not, is directly related to the degree of uniform ink brush and ink, directly affects the quality of printed matter, and it also directly affects the other aspects, such as the service life of rubber roller, etc. Among the ink roller contact pressure to maintain uniform, appropriate, such as pressure slants big, can make the rubber roller compression deformation, colloid due to excessive heat expansion, ink is heated and it's easy to get loose, even degumming, affect the quality of the printing ink; On the other hand, and easily damaged glue roller head (bearing) or shaft hole. Ink forme roller height adjustment is also very important, too high will cloth uneven ink, too low, easy to scratch colloid, and intensifying plate wear. Ink forme roller contact with the plate, generally can be put on the plate a strong toughness about 40 g/m2, when ink forme roller rolling up note after pulling a sense of compression resistance.

    Rubber roller to adjust the height and the UV printing structure also has a relationship. If it is color printing with UV printing, rubber roller can be adjusted a bit low, error is + / - 0.5 mm, so that the ink roller to UV ink of printing roller is evener, printed products make people pleasing, otherwise, prone to ink, ink, etc. In the printed word, the height of the rubber roller and basic text version of flat or slightly lower, that can make the printing rubber roller friction plate, gently so that the text printing is very clear and crisp, rubber roller wear surface is not easy to damage, smaller can use plate longer. Adjustment should be used when the glue roller, first remove the plate to glue roller level into pull out a few times, as soon as the ink dot size on the glue roller, the operator according to the different needs of print to determine the degree of UV printing rubber roller, and then put the top wire fastens, such high speed printing rubber roller of high and low will not change.

    Need to be patient when debugging rubber roller, lest appear the following situations: rubber roller surface damage, slag, graphic, text short cut, paste version, jump even glue; Graphic example is differ, UV printing surface even only by mark but no ink; Move too tight and the UV printing rubber roller twist bad, cause equipment accident.
