Swing type embossing mechanism The plastic gravure squeegee printing machine generally adopts the oscillating embossing structure. The web gravure squeegee machine generally adopts the direct pressure embossing structure, and the maximum printing pressure can reach tens of thousands of cattle (at a pressure of 0.7). Mpa time). When the doctor blade printing is required, the piston of the steam lever 5 moves downward, and the back pressure roller 4 is pushed against the upper surface of the impression cylinder 2 to move up and down to complete the pressing with the plate cylinder 1. At this time, the tape is printed between the impression cylinder 2 and the plate cylinder 1. This article will introduce you to the shortcomings of plastic doctor blades.

The left and right movement of the squeegee knife plays an important role in reducing the scraper line, improving the utilization of the squeegee and reducing the wear on the plate. If the squeegee does not move properly, you should find a way to improve it. When there is a line mark in printing, one is causing a plate injury, and the other is that the blade is not sharp. However, another reason is that there is a foreign object stuck behind the blade. The solution is to move the squeegee up and down to remove the adhesive. If it can't be smashed, it can only stop the squeegee.
