When the flexographic printer is started, the feeding / discharging traction roller and motor vibrate violently with a loud noise. At this time, pay attention to check the encoder of the driving motor. The ink layer thickness of the printed product can reach 1-50 μ m. The gear clearance of the swing roll potentiometer can be eliminated by adjusting the p value parameter in the internal PID value of the traction frequency converter. Although the cleaning free process is the development direction, military products should be used carefully.
The non-woven fabric printing machine adopts a drying device, and the printing sheet deformation is small, which is conducive to ensuring the print quality. If there is a fully automatic computer version alignment device, the operation mode should be set to automatic version alignment. The computer can track automatically. In case of deviation, it will automatically send a correction signal to move and realign the version roller or substrate. Another question is to see if the contact surface between the steel mesh and PCB is too far apart, or if the tin paddle can not be scraped clean even if it is dry. This problem is not very complicated. It is not difficult to deal with it by observing the actual situation.
