How about flexo squeegee?
Whether the squeegee is used in the ink transfer system is optional. For rough printing or UV glazing, it is not necessary to use a squeegee, just adjust the pressure between the rubber squeegee and the anilox roller. A substantially uniform ink layer can be obtained. For the printing of general printed products, the squeegee should be used. At this time, the pressure between the rubber roller and the anilox roller should be smaller to ensure that enough ink is evenly applied to the squeegee blade, so that behind the squeegee In order to get a uniform ink layer. In addition, the screws on the squeegee holder should be carefully adjusted. The screws can change the contact pressure between the squeegee and the surface of the anilox roller. If the above method does not work, that is, if the smooth and uniform ink layer is still not obtained, the squeegee blade can be inspected to see if it is physically damaged or raw, or the screw of the fixed squeegee holder is loose, causing the blade and the net. The roller axes are not parallel. Do not easily scrap the squeegee with small defects. You can use the randomizer on other vacant printing units and use it after the defect has been removed. A squeegee can continue to be used even if it is milled a few millimeters in its lifetime. This article will introduce you to the flexo squeegee.
Such periodic fluctuations not only have a certain influence on the plate roller base, but also the effect on the doctor blade is very obvious. The long time vibration will make the doctor blade scrape dirty, resulting in dirty version. A phenomenon occurs. By increasing the pressure on the doctor blade pressure, the problem can be solved in a short period of time, but the problem cannot be solved fundamentally, and it also has a significant impact on the service life of the doctor blade.
The polishing quality of the surface of the plate roller is mainly manifested by the number of burrs around the cell. The good quality plate has a clean, no burr, and the cells are clear and there are no impurities inside. This ensures that the plate roller does not damage the doctor blade during the printing process. After the squeegee is frequently replaced, if there is still a ruled line on the printed product, it can be generally determined that there is a problem of polishing quality of the plate roll.
If the gap on the squeegee is relatively small, it can be polished with oil stone or fine sandpaper until the hardness of the smooth squeegee is lower than the hardness of the chrome layer on the surface of the printing plate. If the hardness of the squeegee is too high, it will accelerate the wear of the printing plate and cause scratches: if the squeegee is of poor quality, it will wear out in a short period of time, resulting in the ink of the printing plate not being cleaned and the slash line appearing. At this time, it is necessary to frequently adjust the knife and change the knife.
