The anilox roller is the heart component of flexographic printing machines, and its impact on printing performance is crucial. While the selection and configuration of anilox rollers are important when selecting printing equipment, improper maintenance measures will greatly reduce the service life of anilox rollers. The daily maintenance of the mesh roller should include the following points:

Bagging machine, bubble film machine, red envelope machine, flexographic printing machine, high-speed paper mounting machine, label removal machine, dressing sticking machine, retention needle sticking machine, hydrocolloid machine, medical rolling cutting machine, medical die-cutting machine, plaster rolling cutting machine, stainless steel water tank bubble film machine, label removal machine, gravure printing machine, mask machine, rolling cutting machine

It is strictly prohibited to scrape, touch, or collide with the mesh roller on the Ruiyite die-cutting machine, flexographic printing machine, mouth bag making machine, foot sticking machine, Kangruide gravure printing machine, electronic shaft gravure printing machine, hydrocolloid machine, wound pasting machine, flexographic printing machine, non-woven bag making machine, roll paper printing machine, medical paper printing machine, roll cutting machine

(1) Keep the equipment clean and tidy. In addition to maintaining environmental hygiene around the equipment, it is also important to keep the equipment clean, especially the protective cover, to prevent ink residue from falling between the mesh roller and the rubber roller inside the protective cover; Ruiyite die-cutting machine, flexographic printing machine, stoma bag heel sticker, Kangruide gravure printing machine, electronic shaft gravure printing machine, hydrocolloid machine, wound sticker machine, flexographic printing machine, non-woven bag making machine, roll paper printing machine, medical paper printing machine, roll cutting machine

(2) Use clean ink. After using ink for a period of time, due to various reasons, it may contain impurities or sand particles, or some ink itself may contain impurities or sand particles. Therefore, before using ink on the machine, it is best to filter it once with a filter screen of 100 mesh or more, and add a magnet at the ink inlet pipe of the ink supply system; Ruiyite die-cutting machine, flexographic printing machine, stoma bag heel sticker, Kangruide gravure printing machine, electronic shaft gravure printing machine, hydrocolloid machine, wound sticker machine, flexographic printing machine, non-woven bag making machine, roll paper printing machine, medical paper printing machine, roll cutting machine

(3) Ensure that the erasing cloth is clean. This is a problem that is easy to overlook. Many printing machine operators in packaging factories casually throw the erasing cloth on the floor after wiping the printing plate, which easily causes sand particles on the floor to adhere to the erasing cloth and be carried by the printing plate onto the mesh roller, causing scratches on the mesh roller; Ruiyite die-cutting machine, flexographic printing machine, stoma bag heel sticker, Kangruide gravure printing machine, electronic shaft gravure printing machine, hydrocolloid machine, wound sticker machine, flexographic printing machine, non-woven bag making machine, roll paper printing machine, medical paper printing machine, roll cutting machine

(4) Pay attention to the quality of the original paper. There are a lot of impurities on the surface of the original paper, and ink has a certain viscosity. When the printing plate comes into contact with the cardboard with ink, it may also take away the impurities on the surface of the original paper and transfer them to the mesh roller, causing damage to the mesh roller, especially some larger particles of impurities;

(5) When replacing or cleaning the mesh roller, it is prohibited to hit the mesh roller and careful care should be taken. If the mesh roller is hit, it can easily damage the mesh holes and affect the printing effect; If severe, the entire mesh roller will be scrapped.

Do a good job in cleaning the mesh roller

(1) Do a good job in daily cleaning of the mesh roller. After working for a whole day, there is still a lot of ink accumulation at the bottom of the mesh hole of the mesh roller. If the ink in the mesh hole is not cleaned in time, it will be very difficult to clean it again when the ink dries up at the bottom of the mesh hole. Thoroughly clean the ink in the mesh hole. We need sufficient cleaning time to use a copper or steel brush and washing machine water for cleaning.

(2) Regularly clean the mesh roller thoroughly. Even if the daily cleaning work of the mesh roller is done well, it is inevitable that ink residue will remain at the bottom of the mesh hole and dry up. This phenomenon can be clearly seen under a high-power magnifying glass. Therefore, it is necessary to regularly and thoroughly clean the mesh roller, such as using specialized cleaning solution, ultrasonic cleaning method, low-pressure spray cleaning method, dry ice cleaning method, chemical solvent soaking method, etc. Ruiyite die-cutting machine, flexographic printing machine, stoma bag heel sticker, Kangruide gravure printing machine, electronic shaft gravure printing machine, hydrocolloid machine, wound sticker machine, flexographic printing machine, non-woven bag making machine, roll paper printing machine, medical paper printing machine, roll cutting machine

There are still a few aspects to pay attention to

(1) For the chamber scraper system, attention should also be paid to the following aspects:

① Clean the mesh roller with clean water. The chamber scraper system generally has an automatic cleaning function. At this point, where does the cleaning water come from? Tap water or groundwater? In fact, tap water is not clean either, and the sand particles it contains have become the killer of the mesh roller.

② Regularly clean the metal plate holding the scraper. Open the metal plate holding the scraper and you will see shocking things such as ink residue, rust, impurities, etc. If not cleaned up in time, these are also the killers of the mesh roller;

③ It is necessary to ensure the sealing of the ink supply system and preferably install a filtering device (120 mesh or 140 mesh) at the ink inlet.

(2) For ceramic mesh rollers, attention should also be paid not to approach heat sources. Excessive temperature can cause the ceramic layer of the ceramic mesh roller to peel off.

The maintenance of the mesh roller can be determined by observing its appearance and inspecting it with a magnifying glass. A well maintained mesh roller with a clear surface, consistent color and luster, no obvious color spots, and no obvious scratches or damage observed under backlight; Improper maintenance of the mesh roller results in a blurry and dull surface with obvious color spots. If there are scratches or damages, they can be seen by backlighting. Observing under a high-power magnifying glass, it is clear at a glance whether the mesh hole is clean or not. Manufacturers with conditions can also use a density meter to test and evaluate the density of the printing site, which can determine whether the anilox roller is clean.
