The three main precautions of the roller.PVC bag solding machine

　　① Clean the roller with clean water. The chamber scraper system generally has an automatic cleaning function. Where does the water for cleaning come from? Tap water or ground water? Is tap water clean water? We may as well let the tap water flow through a 140 mesh filter, and we will soon find that there are a lot of sand on the filter. Not to mention groundwater. These grains of sand become the killer of the roller;

　　② Clean the metal plate holding the scraper regularly. Open the metal plate holding the scraper, you will see shocking things: ink residue, rust, impurities, etc., if they are not cleaned up in time, they are also the killer of the mesh roller;

　　③ To ensure the sealing of the ink supply system, and it is best to install a filter device (120 mesh or 140 mesh) at the ink inlet, which is very necessary. For the ceramic roller, it should also be noted that it is not close to the heat source. Too high temperature will make the ceramic layer of the ceramic roller fall off. How well the roller is maintained can be determined by observing its appearance and checking with a magnifying glass. The well-maintained roller has clear surface, consistent color and luster, no obvious color spots, backlight observation, no obvious scratches or damage; And improper maintenance of the roller, the surface is fuzzy, dim, there are obvious stains, such as scratches or damage, backlight can be seen. Under a high-magnifying glass, it is clear whether the net is clean or not. Conditional manufacturers can also use the density meter to detect and evaluate the density of the printing field, which can determine whether the roller is clean.
