Rewinding Machine common fault - Paper roll end faces are not aligned
1. Top core movement - Check the top core plane bearing and lock nut and adjust the clearance.
2. The top core force is not enough - check the air motor.
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 ---
8 core filling
The core loading device supplies a paper core between the take-up rolls.
A fork-like paper core loader is mounted on the paper feed roller. The core loader includes a paper core clip and a centering tray. The core loader is hydraulically operated. The movement of the paper core clamp is operated by compressed air.
The core is placed on a tray in the core loader. It is fixed in position by the paper core clamp.
During the rewinding process, the core loader opens and the new core is advanced. When the core loader is full, the paper core clamp will run to grip the paper core. The core loader moves to the position it should wait when the paper feed roller moves. When the paper advance roller reaches the position where the paper roll is ejected, the core loader is lowered to the drop position. The core holder is opened and the core falls into the middle of the roll.
