First, the process requirements
The coating machine needs glue or ink material to be evenly adhered on the surface of aluminum foil, plastic film or cloth textile, which requires high coating process, not only requires uniform coating height, but also high-speed non-stop coil change to improve production efficiency.
Second, the program advantages
1, By the frequency converter to complete tension control at all levels, the use of tension sensor tension control, the system is simple and stable. Use PLC or synchronous controller to control the drive roller drive speed, at the same time as the other drive line speed signal.
2, S350 closed-loop tension control (sense of vector control) Easy to achieve acceleration and deceleration in the process of constant tension and save the installation of tension roller space, reduce mechanical costs, while high-precision control to ensure a high degree of uniformity of the coating effect.
3, Double-station retractable volume with pre-drive function to meet the high-speed non-stop automatic roll change, improve production efficiency. At the same time accurate winding control, so that the winding effect is better.
