The use of printing press roller and bearing maintenance care

Regardless of any kind of printing machines, machine after putting in place a new equipment, must first by technicians and collar machine device printing rubber roller. Rubber roller device and necessary reasonable debugging, it must be in contact with the ink roller and plate, both be short of one cannot. All knew letterpress printing of practitioners of height is 3. 14 mm, and the height of the type is divided, and relatively low PS version 1. 2 mm, so when the rubber roller device debugging must know fairly well. If be printing color printing quality, lower roller is adjustable, error of plus or minus 0. 5 mm, so that the ink roller to the printing rubber roller ink than average, and reflected onto the plate printing roller has the same effect, make the person find the scenery pleasing to both the printed products, if not, will present the phenomenon such as ink, ink way. When printed word, the height of the rubber roller can be flat or slightly lower with the text version, so can make the printing rubber roller friction plate quietly, so that the word printing is very clear, clean and agile, rubber roller wear surface is not easy to damage, smaller can extend the use of the plate. Adjustment should be use the glue roller. Apply to remove the plate before let glue roller degree into pull out a few times, the ink dot size on the glue roller immediately apparent, the operator can be sure according to the different needs of printing printing rubber roller up and down, and then put the top wire rope. So when high-speed printing rubber roller up and down will not change. 'If we lack of patience when applying glue roller, debugging graph save trouble, slow and steady will render the following conditions:' A. Rubber roller represent physical damage, drop of slag, make the text printing pen broken, missing word ambiguity, and presents the paste blind, jump glue phenomenon. B。 Different text example that appear as long as the word mark no ink printing quality appearance. C。 If the rubber roller and debugging to the ink rubber roller is too tight, will make printing rubber roller twisting form bad economic loss and equipment accidents. 02 printing rubber roller remaining in the offset printing technology is the key of water and ink balance control, road and ink balance is the key components, rubber roller, ink roller its quality can be directly applied to produce quality quantity. Intaglio printing, letterpress and flexo. Ordinary printing enterprise every week a care equipment, including printing rubber roller die. There are several ways to care: 1. Every day should be carefully cleaned after the completion of the consumption operations, rubber roller, repeat twice; 2. Cleaning printing rubber roller must use the specified chemicals, such as industrial alcohol, etc. , can't use corrosive solvent; 3. Holiday during the break to remove the rubber roller, avoid compression deformation; 4. About printing rubber roller appearance maintenance should be taken to a news paper, placed ventilated dark place. 03 common treatment method of rubber roller problem between a rubber roller pressure is overweight, can increase the friction between the rubber roller, the roller heating heating, increase squeeze the contraction between rubber roller, accelerate the aging and deformation of the rubber roller, to speed up the ink and water emulsion process, this is not conducive to ink transfer. The solution: the pressure between the rubber roller should and contact pressure on the layout fundamental differences. Experience is to use a 1500 yarn, 3 cm wide plug inserted between rubber roller, can feel a certain tension. After scrubbing, use clean cloth to wipe it again then put rubber roller to the machine, in order to use next time. Problem two disposal appearance crystallization blocked the rubber roller appearance of wool stoma, deprive rubber roller ink role, form the ink transfer is not average, easy to present ink emulsification. The solution: to unload of the machine, rubber roller, with flat shelf, take cloth glued kerosene and pumice, evenly rub hard rubber roller appearance, crystallization layer erase the rubber roller appearance, show the original plastic roller rubber color, then use the car wash water or gas residue on the rubber roller kerosene and pumice, cleaning, clean, devices and recuperate good rubber roller pressure again. 04 about bearing on the rubber roller bearing in the high-speed operation of the machine, bearing wear is obvious, plus operators often don't pay attention to care of bearing, wear is more fierce. Rubber roller shaft after receive the damage to a certain level, can produce rubber roller beating the friction and extrusion, shorten the using life of roller, and can make the printed products are 'ink, water bar' phenomenon. So request operators once a week to take off the rubber roller, called bearing butter, who wear too fierce, turn the bad bearing change, ensure the normal use of roller.
