Rewinding Machine Structure - Control Performance Indicators
The rewinder is the last process in the papermaking process. The performance of the rewinder determines the quality of the finished paper roll. A complete rewinder must have the following properties:
1. Adjusting mechanism of pressure of the platen roller
2, support roller torque program control
3. Tension adjustment mechanism
4. Electric drive "flexible" start and proper speed program control.

Part II: Hydraulic and pneumatic parts:
, pneumatic system
Components for pneumatic systems use brand-name products. Pneumatic control section includes
1) Paper feeding device 2) Paper cutting device 3) Pressure roller lifting ratchet protection device
4) Paper roller frame lifting ratchet protection device 5) Curved roller group angle adjustment
6) Safety protection devices, etc.
Part III: Electrical Section
First, the performance introduction
1. Transmission system adopts AC sub-transmission, with rectification feedback unit and common DC
Busbar and inverter unit + variable frequency motor.
2. Tension detection and tension closed-loop control system, paper roll tension control system.
3. Pressure detection and pressure closed-loop control system of pressure roller.
4. Security protection system. 5. Paper roll diameter measurement.

3. Adjust the curved shaft behind the punching knife. The curved shaft is finally stretched as a smooth transition axis before the web is wound up. The position of the position and the working arc size not only affect the smoothness of the paper web, but also affect the stability of the web transport. When the curved axis is too high, the paper web is scratched by the punching surface knife, and the jitter is large and the paper is easy to break. When the position is too low, the paper web is scraped to the low hole and the broken layer is easy to break. Generally, the height of the curved shaft position is adjusted so that when the paper web passes through the punching knife, the bottom layer is preferably 5~8 mm higher than the punching bottom knife, and the working arc of the curved shaft is as small as possible, and the paper can not wrinkle.
