Rewinding Machine safety operation guide -
Fourth, joint operator joint quality:
Joint quality control
1 tape should not be exposed; prevent sticking between sheets.
2 The outer sheet of the joint must be flattened, straightened without wrinkles, and the end surface is not protruding.
3 When the joint is cut, the paper edge shall not be larger than 5mm and neat.
4 The outer tape of the joint must be a straight line.
5 connector label placed at the joint
6 The number of joints should be less than the specified value.
Automatic rewinding machine speed ratio adjustment method ---
2. Adjust the paper-pressing gap of the platen roller so that the paper web can be smoothly conveyed between the paper feeding belt and the winding roller. The rear platen roller is the intermediate link of the paper web conveying process. If the adjusted gap is too small, the paper web is easy to wrinkle and sag. When the gap is too large, the three layers of paper are not combined together to facilitate delamination and fault, which affects the speed of the paper feed and Rewind quality. When adjusting the paper-pressing roller, the paper-pressing gap should be gradually increased from small to large, so that the paper web can be locked without sag and not drooping.
Design and application of constant tension and load distribution control for winder---
1. Rewinder structure and working principle
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.
