Rewinding Machine common fault - The coil is not tight during operation
1. Unwinding tension controller is not open - Open unwinding tension controller switch
2, did not press the reset button - press the reset button on the two tension controllers
3, the unwinding tension controller tension is too small - increase the unwinding tension controller output current
4, tension controller failure - contact the manufacturer
Guolian High Speed ??Slitting Rewinder Technical Description ---
Third, the function introduction
1. The tension control of the eject roller consists of a tension sensor and an eject motor.
In the loop control loop, the paper take-off motor is an electric motor when unwinding, and is a brake generator during normal operation and parking.
2. The pressure control of the pressure roller is controlled by various sensors such as the take-up roller diameter detecting sensor.
Forming a closed-loop control system, there are three pre-made curves for different paper grades and different finished paper diameters for the operator to choose, and the actuator will be controlled according to these three different pressure curves.
3, between the two take-up bottom rollers, take the torque difference control method, corresponding to no
The same take-up diameter, the torque between the front and rear bottom rollers is distributed in different proportions.
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.
