Rewinding Machine common fault - The coil does not run or is broken
1. Winding tension controller is not open - Open winding tension controller switch
2, the speed of the governor is too low - increase the speed of the governor
3, did not press the reset button - press the reset button on the two tension controllers
4, the tension tension controller tension is too small - increase the winding tension controller output current
5, unwinding tension control tension is too large - reduce the unwinding tension controller output current
6, the running button is damaged - replace the run button
7, tension controller failure - contact the manufacturer
8, governor failure - contact the manufacturer

Guolian High Speed ??Slitting Rewinder Technical Description ---

Second, the system configuration
1. Main transmission part: 1 set of paper-removing brake generator, 400kW (YVP4501-6 or
1LA8357-6), one roller motor (YVP225S-4), 37kW, two pressure roller motors (YVP132S-4), 5.5kW, two coiling motors (YVP355L2-4) (one for each front and rear roller) , 315kW, 6 paper cutter motor, 0.55kW, total installed capacity 1082kw (model and power are subject to final design). The rectification feedback and the inverter unit and the tension controller matched with the above constitute a transmission control system.
2. Logic control part: PLC host 1 block.

Design and application of constant tension and load distribution control for winder---

1. Rewinder structure and working principle

1.2 Working principle
The paper web is taken out from the paper take-off roller (in this paper, the lower paper feeding method is adopted), and the paper guide roller passes through the slitting mechanism, and is wound from the bottom between the front and rear bottom rollers, and then wound on the paper core. There are 1 support rollers in front of and behind the slitting mechanism, and the front and rear support rollers are equipped with tension sensors for measuring the tension of the web. The platen roller above the core ensures the hardness of the roll. Each component of the winder is driven by a separate motor. The working principle is 3: the original paper roll taken from the paper machine is placed on the unwinding roller, and the brake on the unwinding roller maintains a certain tension of the paper web, and Quickly brake the paper roll when the head is broken. The paper web passes through the guiding roller to reach the slitting device, and several slitting circular cutters divide the paper into the required width, and then send it to the take-up roller for rewinding. After reaching the specified length, the paper is stopped and replaced with a new paper core. Repeat the above process. The main structural parameters of the winder are the width of the paper that can be processed and the maximum speed, followed by the maximum diameter of the paper and roll, the method of cutting and the length.
It can be seen from the working principle of the winder that the motor of the take-up roller drives the corresponding take-up roller to rotate the paper-wound paper core, the diameter of the paper roll gradually increases, and the axial center of the paper roll increases with the diameter. Gradually moving up, the platen roller moves up and gradually reduces the pressure. The unwinding motor mainly provides a reverse torque, creating tension on the paper surface, keeping the paper web flat, and the speed control of the unwinding motor is a process of gradually increasing speed, but the linear speed of the paper web remains unchanged.
