    Author: Click:1395 Release time:2020-07-23

      1、 Process requirements

      The coater needs to evenly adhere glue or ink substances to the surface of aluminum foil, plastic film or cloth textiles. It has high requirements for the coating process. It not only requires uniform coating height, but also can realize high-speed non-stop roll change to improve production efficiency.

      2、 Scheme advantages

      1. The frequency converter completes the tension control at all levels, and the tension sensor is used to realize the tension control. The system is simple and stable. PLC or synchronous controller is used to control the speed of the drive roll frequency converter, and it is used as the linear speed signal of other frequency converters.

      2. S350 closed-loop tension control (inductive vector control) easily realizes constant tension in the acceleration and deceleration process, saves the space for installing tension rollers and reduces mechanical costs. At the same time, high-precision control ensures that the coating effect is highly uniform.

      3. It has the function of high-speed stop and automatic rewinding and rewinding, which can improve the production efficiency. At the same time, accurate winding control can avoid the bad winding of vegetable heart type and make the winding effect better.
