1. The whole machine is controlled by 5 frequency conversion motor, and the tension (unwinding, coating, traction and winding) of the whole machine is automatically controlled by Mitsubishi PLC system. The reliability of the whole machine tension is improved by touch screen control and display of human-machine interface.
2. The form of discharging rack is electric turnover double position, and magnetic powder automatic tension control is adopted.
3. Moire coating method: the coating scraper shaft adopts heavy-duty double shaft mechanical independent swimming, the scraper adjustment mode is manual and pneumatic, and the angle can be adjusted at will. The coating amount depends on the mesh line of the moire roller, and the moire roller with different mesh line can be changed for different coating amount.
4. In order to make the coating uniform, a set of uniform cots is equipped, which is controlled by the motor frequency converter.
5. Transfer coating of Maier bar: stainless steel wire scraper is used, which is supported by the bar. The coating amount depends on the thickness of the stainless steel wire scraper. Different coating amount can replace different thickness of stainless steel wire scraper.
6. The oven is 30 meters, divided into 10 sections, with independent temperature control, electric heating, hot air entry drying system, adjustable internal circulation suction and exhaust device, strong air inlet and exhaust, and complete drying.
7. The guide wheel in the oven is synchronous with the host, and the grid conveyor belt transmission is adopted to reduce the material stretching and deformation. The air top oven and the film piercing operation platform make it easy for the operators to work.
7. The intermediate tension between coating roll and traction steel roll is synchronously controlled by floating arm
8. Automatic meter and speed control device
9. EPC alignment machine is used for deviation correction, so as to make the material winding neat.
10. Key type air expanding shaft is adopted for retracting and releasing shaft, which is convenient for loading and unloading.
11. High precision up pressure traction device, water circulation type is adopted for steel roll cooling, through which the film is smoother, smoother and more effective.
12. The form of take-up rack is side take-up, and the take-up drive and traction are used together.
