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
Design and application of constant tension and load distribution control for winder---
1. Rewinder structure and working principle
The rewinder is a paper roll produced by a paper machine, which is slit, finished, and re-rolled into a roll paper or other type of paper with a certain width and length and tightness to meet the printing memory package. Industrial needs. The performance of the rewinding machine will affect the output of the entire paper machine production line.
The rewinding machine has many forms. According to the nature of the reel, the rewinding machine can be divided into a shaft rewinding machine and a shaftless rewinding machine: according to different rotation modes, it can be divided into single motor transmission and double motor rotation. In this paper, we are transforming a double-bottom roll-feeding rewinding machine, each of which has its own motor drive.
Belt rewinding machine design and working principle ---
rear bottom roller
The movable beam is fixed to the frame. The movement of the platen roller beam moves with the hydraulic cylinder attached to the beam. The platen roller is decoupled from the hydraulic cylinder during the rewinding process. The platen roller also includes a pressure sensor to measure the pressure between the platen roller and the frame.
The platen roller has a position measuring device for providing a position about the platen roller and the diameter of the paper roll. Based on the above information, the hydraulic cylinder moves in accordance with the separation design curve as the diameter of the paper roll continues to increase. The hydraulic cylinder is equipped with a hydraulic hose rupture protection valve to prevent the paper roll from suddenly falling when the hose is damaged.
The platen roller provides additional load to the paper roll at the beginning of the rewinding. At a later stage of the rewind, the pressure is released. In the final stage, the platen roller ensures that the paper roll is in place.
During the threading and changing process, the platen roller is raised to the rear of the safety lock at the top position. The safety lock prevents the platen roller from suddenly falling when the device malfunctions. The platen roller is automatically decompressed when the platen roller is lowered to the core or the base. If the lowering control is terminated before decompression, the platen roller will be activated and the platen roller will be raised to the upper position.
During the rewinding process, the contact surface between the platen roller and the paper core must be carefully observed. If the platen roller is very close to the core, special care must be taken during the rewinding process. If the core starts to vibrate, the speed must be lowered immediately. There is a vibration indicator on the pressing roller beam to facilitate speed reduction in that case.
