The principle of coating application for lithium batteries

Suitable for shoe materials, electronics industry, sponge, EVA, PE, fabric and other adhesive applications.

Tension system

1. Process requirements: The lithium battery coating machine needs to evenly adhere adhesive or ink substances to the surface of aluminum foil, plastic film, or fabric textiles. The coating process requirements are relatively high, not only requiring uniform coating height but also the ability to achieve high-speed non-stop roll changing to improve production efficiency.

2. Advantages of the solution: The lithium battery coating machine is controlled by a frequency converter for various levels of tension, and tension sensors are used for tension control. The system is simple and stable. Use PLC or synchronous controller to control the speed of the drive roller frequency converter, while also serving as the linear speed signal for other frequency converters. S350 closed-loop tension control (inductive vector control) easily achieves constant tension during acceleration and deceleration, saving space for installing tension rollers and reducing mechanical costs. At the same time, high-precision control ensures highly uniform coating effects.

3. The dual station unwinding and rewinding system has a pre drive function, which can meet the needs of high-speed non-stop automatic roll changing and improve production efficiency. At the same time, accurate winding control can avoid poor winding in the form of a vegetable heart, resulting in better winding effect.
