The coater applies a layer of glue, paint or ink with specific functions on rolled substrates, such as paper, cloth, leather, aluminum foil, plastic film, etc., and then rolls them after drying.

The electric drive control is divided into constant tension unwinding, multi-level synchronous control of coating process and constant tension winding. It is required that the tension of base material is constant, the linear speed is constant, and the starting and stopping process is smooth during normal production.

System advantages

1. Tension control and synchronization control are all completed by frequency converter, no additional controller is required, and the electric control system is simple in structure.

2. Modular structure design is adopted. Although the production line is long and there are many links, debugging, operation and maintenance are very convenient.

3. For the special model, the factory value can meet the system requirements without resetting the inverter parameters.

4. The production process has constant tension, high control accuracy, no damage to the substrate, uniform coating effect and good product quality.

5. The winding tension of finished products is constant, completely avoiding the condition of internal tightness and external looseness.
