Rewinding Machine safety operation guide - 

Seventh, production operations and quality control during the rewinding process:
1. The speed must be slow when rewinding, and the inspector should check the appearance quality of the paper.
2, often check the quality of the paper, found that the paper disease stopped in time, to the inspector on duty
Report and contact the upper and lower processes to strip off paper with quality problems. The rewinding can be continued after the inspector confirms.
3. When rewinding, pay attention to the situation of broken ends, trimming, etc., and control the tension of the paper during rewinding.
The car is tight) to keep the inner and outer tension of the paper roll consistent.

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.

1. Rewinder structure and working principle

1.1 Structure
The rewinder is generally composed of a unwinding roll (also referred to as a paper take-off roll), a guide roll, a slitting mechanism, a platen roll, a take-up bottom roll (including a front bottom roll and a rear bottom roll), and a double bottom roll. The machine is characterized by two rotating drums to replace and support the take-up reel, usually with or without a rotating platen roller pressed against the top of the reel in the take-up, the take-up reel is taken up The main structure (has become the front and rear bottom rollers respectively). Under normal circumstances, the surface of the front bottom roller is rough, and the surface of the rear bottom roller is relatively smooth. They are connected to the motor through the reduction gear box. The platen roller, also called the load roller, acts to create a downward pressure whose pressure is the difference between its own weight and the load roller lifting pressure. The unwinding roller is composed of a leg paper holder, a unwinding roller coupling, a unwinding roller clamping mechanism, and a unwinding motor. Longitudinal cutters generally have book holders side by side on the same axis, mainly used to cut off the change. Cut a certain width of sheet paper to the required width as needed. Two tension sensors are placed on the tension roller to receive the web tension.
