How to maintain the roller of carton machine press
The anilox roller is one of the core components of the carton mechanical flexographic ink printing machine, and it is very important to the printing effect. Therefore, when purchasing printing equipment, the selection and configuration of anilox roller is very important. However, in addition to this, whether the maintenance measures for the anilox roll are in place in the subsequent use will also have an important impact on the service life and printing effect of the anilox roll. Here, the editor will introduce how to maintain the printing effect and service life of the anilox roller through daily maintenance.
First of all, avoid any physical damage to the anilox roll, such as scratches, bumps, scratches, etc. In daily use, users need to do the following: 1. Keep the equipment clean, especially the protective cover used to isolate sand and dust, to prevent the ink residue in the protective cover from falling between the anilox roll and the rubber roll and damaging the anilox roll. 2. Use clean ink. The ink may contain impurities or sand particles. These impurities or sand particles will cause serious damage to the anilox roll as the ink continues to circulate in the ink supply system. Especially when using a scraper to scrape the ink system, the sand particles in the ink are very easy to leave scratches on the anilox roll. Therefore, before ink is used, it is better to use a filter screen with more than 100 meshes to filter impurities, and add a magnet at the inlet pipe to remove metal impurities. 3. Ensure that the plate wiping cloth is clean. The cloth used for wiping the printing plate should be kept clean to avoid sand impurities and prevent sand particles from being carried onto the anilox roll by the printing plate.
Secondly, clean the anilox roll. In daily use, the following points need to be done: 1. Develop the habit of cleaning the anilox roll daily, and have enough cleaning time. After the completion of daily printing work, ink will accumulate at the bottom of the mesh hole, which needs to be cleaned in time to prevent the ink from drying up at the bottom, causing difficulties in cleaning; The cleaning time usually takes about one hour, so that the ink accumulated at the bottom of the mesh hole can also be fully dissolved in water; 2. Use proper cleaning tools and cleaning agents. Use copper brush to clean metal anilox roll, steel brush to clean ceramic anilox roll, and use machine washing water to clean ink, which will be more thorough and convenient. 3. Thoroughly clean the anilox roll regularly. After all, the daily cleaning is not thorough enough, and it is inevitable that there will be ink residue, which will be accumulated for a long time. It is still necessary to thoroughly clean the anilox roll with a special cleaning method. There are many ways to clean the anilox roll on the market, and I will briefly introduce several methods here. Please consult the anilox roll manufacturer for specific precautions.
1) Use special cleaning fluid. The special cleaning solution can re-wet the ink dried at the bottom of the mesh hole for easy cleaning.
2) Ultrasonic cleaning method. The dried ink is crushed by high-frequency acoustic wave and then washed with cleaning solution. This method needs to grasp the cleaning time to prevent damage to the mesh structure due to too long acoustic wave cleaning time.
3) Low pressure jet cleaning method. Use soda powder as cleaning powder, spray the anilox roll under low pressure, and wash the stubborn ink. However, it should be noted that the injection pressure should not be too high, otherwise it is easy to damage the mesh hole.
Finally, how do we know whether the anilox roll is cleaned and properly maintained? In fact, through simple observation, it can be seen that the properly maintained anilox roll has a clear surface, consistent color and luster, and will not have obvious color spots, and will not see obvious scratches or damage when viewed with backlight; However, if the anilox roll is not properly maintained, the surface is fuzzy and dim, with obvious color spots, and scratches or damages will be seen when backlighting. At the same time, under the high-power magnifying glass, you can also see whether the mesh hole is clean. Of course, qualified manufacturers can also use a densimeter to detect the density of the printing site, which can also determine whether the anilox roller is clean.
The above is about how to maintain and maintain the anilox roller, the core component of the carton mechanical ink printing machine.
