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 ---
3. Platen roller power:
A motor that drives the platen roller by a timing belt drive is mounted on the platen roller beam. The coupling between the individual bearings of the platen roller ensures that the speed of each combined reel is the same. The speed of each part of the platen roller is the same during operation.
Platen roller photocell:
There is a photocell at the end of the platen roller beam. If the paper or any other obstacle enters the photocell illumination area, the photocell signal will immediately stop the downward movement of the platen roller. During operation, the photocell's monitoring paper does not wrap around the platen roller. If something happens, the photoelectric signal activates the alarm to stop the rewind.
2- top core head
3- drive motor
4- positioning stop pin
5- Safety lock in the top core lock
The core between the drums is locked before the rewinding process begins. Keep the paper roll in place during the running of the paper core locking process.
The core lock device includes a paper core plug, a cone, and a sleeve. The core of the paper core is fixed in a core seat that can be vertically up and down and can reduce friction. The core of the paper core is supported by the upper bearing of the cone, so it rotates freely. The locking of the core and the upward movement of the core locking device are done hydraulically. The vertically moving hydraulic cylinder supports the weight of the core collet so that the home can rise as the diameter of the paper roll increases. The change in the slit width is adjusted with the help of the hydraulic transfer knob. The paper core collet has a relatively low position on the locating pin. As the paper core model changes, the latch and the paper roll chuck must change. The core collet structure has a shock absorber that is lowered onto the positioning stop pin at the core of the paper core. The safety lock has a compressed air cylinder open.
Before the rewinding begins, the collet is knocked into the paper core. The locking cylinder of the operating side core collet has a locking pressure that is less than the drive side. If the core is too long, the operating side cylinder will retract. As the size of the paper roll continues to increase, the paper core collet moves with the paper roll, preventing the paper roll from moving laterally.
Before the paper roll is pushed away from the winder, the paper core chuck is unlocked and moved to the upper position. The appropriateness of the width of the paper core collet is related to the cutter positioning device. The sensor mounted in the paper core chuck records the pulse as the spool rotates. These pulse signals are not used to calculate the paper roll diameter. There is a sensor in each side of the cone. If one side of the sensor is damaged, the other side can be used immediately.
