The rewinding / unwinding mechanism is mainly composed of single axis manual rewinding, automatic tension control, automatic deviation correction and other functions. The traditional passive winding of magnetic powder is abandoned. When controlling the winding tension, the concept of "taper tension" is used, that is, the tension changes gradually during winding, which avoids the phenomenon of winding core pulling caused by loose inside and tight outside. The automatic deviation correction system adopts ultrasonic detection, which is sensitive. The evenness of both sides of the winding is ensured.

·The scraper drives the turbine worm reducer through the servo motor, drives the high-precision screw rod to drive to the inclined block, transmits the up and down movement of the scraper through the horizontal movement of the inclined block and the inclined block, and the clearance adjustment is set through the touch screen, so the operation is convenient.

·The coating steel roll driving servo motor is connected with the steel rod through a double diaphragm coupling. The steel roller bearing adopts high-precision imported bearing. Through unique installation method, it can ensure that the runout after installation is less than 1.0um. The disassembly and assembly of steel roll is simple and convenient for later maintenance.

·Compared with the traditional coating cot mechanism, the driving motor is fixed and connected by double diaphragm coupling, which avoids the influence of motor vibration on coating, ensures the coating accuracy, and avoids the motor and cot moving back and forth together, prolongs the service life of the motor, and reduces the inertia of the cot during inter coating.

·The driving mechanism of the coating cot connects the motor and the cot through a screw rod, which converts the rotary motion of the motor into the forward and backward movement of the cot. The rubber roller seat and motor are installed on the movable sliding block, with fast response and high precision.
