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:
1. Hydraulic part:
The local hydraulic system consists of a hydraulic pump station and a valve station. System control and transmission components use world famous brand products. All hydraulic lines of the winder are supplied.
The hydraulic pump station uses three oil pumps to provide pressure oil source. The hydraulic station has safety facilities such as liquid level alarm, temperature control, filter blockage alarm, and a set of circulating filtration and cooling system. The valve station control section includes:
1) Ejection shaft ejection and locking device 2) Ejection frame movement 3) Ejection shaft clutch
4) Hook protection device 5) Paper core plug locking device 6) Press roller load reducing device
7) Unloader unit 8) Push roller unit 9) Stop roller holder lifting device
10) Ejection shaft hydraulic disc brake 11) Guide roller hydraulic disc brake
12) Front and rear bottom roller hydraulic disc brakes 13) Head lifting device.
14) Paper core positioning device 15) Paper head clamping lifting device
16) Automatic paper changer lifting device
The hydraulic circuit has the following features:
A. This system adopts superimposed valve, which is simple and compact in structure, convenient in maintenance and installation, and strong in work reliability;
B. The paper return shaft, the guide roller and the two bottom rollers are equipped with hydraulic disc brakes, which assist the brake during emergency braking and share part of the braking torque. Reduce the braking load of the motor, increase reliability, and install an accumulator;
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.
