Rewinding Machine safety operation guide - 

Sixth, change the specification operation:
1. Stop the winder and lift the round knife and tighten the bolts on the base of the round knife.
2. Move the base of the circular knife holder and measure the distance between two adjacent circular cutters with a tape measure to make it conform to
Paper specification requirements.
3. Fix the base of the round knife holder, tighten the bolts, and measure the specifications once again.
Dynamic rewinding (contact angle, tightness, depth).

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.

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.
