In the printing process, some squeegees need to be lapped with the printing plate for a long time to achieve a good squeegee effect. At this time, the edge of the squeegee can be smoothed with metallographic sandpaper to make the squeegee reach Better squeegee effect, and is conducive to the improvement of production efficiency, this article will introduce you to the squeegee manufacturer.
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.
The clutch of the squeegee and the plate cylinder is controlled by a pneumatic piston, which can be adjusted by the piston. Therefore, the squeegee has high pressure regulation accuracy. The front and rear movement of the squeegee is adjusted by an eccentric shaft mounted on the machine, and the stroke of the squeegee is usually 0-10 mm.
