Application principle of coating machine

Use of automatic coating machine
Applicable to the shoe material, electronics industry, sponge, EVA, PE, cloth, etc.
Tension system 1. Process requirements
The coating machine needs to adhere glue or ink to the surface of aluminum foil, plastic film or cloth textiles. It requires relatively high coating process. It not only requires uniform coating height, but also can achieve high-speed non-stop roll changing to improve production efficiency.Stainless steel sheet and furniture PVD coating machine
2. Scheme advantages
The tension control at all levels is completed by the inverter, and the tension control is realized by the tension sensor. The system is simple and stable. Use PLC or synchronous controller to control the speed of the drive roller inverter, and at the same time as the line speed signal of other inverters.
S350 closed-loop tension control (sensory vector control) easily achieves constant tension during acceleration and deceleration, saves space for installing tension rollers, reduces mechanical costs, and high-precision control ensures a highly uniform coating effect. The double-station winding and unwinding has a pre-drive function, which can meet the needs of high-speed non-stop automatic roll change and improve production efficiency. At the same time, accurate rewinding control can avoid dish-style unhealthy rewinding and make the rewinding effect better.
