What is the coating work of the coater manufacturer —

First, the process requirements

The coating machine needs to uniformly adhere the glue or the ink substance to the surface of the aluminum foil, the plastic film or the cloth textile, and the coating process is relatively high, and the coating height is not only required to be uniform, but also the high-speed non-stop changeable roll can be realized to improve the production efficiency.

Second, the program advantages

1. The tension control is completed by the frequency converter, and the tension control is realized by the tension sensor. The system is simple and stable. The speed of the drive roller inverter is controlled by a PLC or a synchronous controller, and is used as a line speed signal of other inverters.

2. Closed-loop tension control (with sense vector control) It is easy to achieve constant tension during acceleration and deceleration, save space for mounting tension roller, reduce mechanical cost, and high-precision control ensures high coating uniformity.

3. The double-station retractable and unwinding volume has a pre-drive function, which can meet the requirements of high-speed non-stop automatic re-rolling and improve production efficiency. At the same time, the accurate winding control can avoid the bad heart-winding and make the winding effect better.
