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.

Guolian High Speed ??Slitting Rewinder Technical Description ---

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;

Belt rewinding machine design and working principle ---

5:Unloading table action
1- Unloading table rise position
2- Middle position of the unloader
The unloading station transfers the paper roll from the winder to the ground.
Construction
The unloader is a device mounted on the floor to remove the paper roll. The platform is controlled by a hydraulic cylinder. The platform is a steel structure. The platform hydraulic unit is equipped with a load relief valve. These are to ensure the control process of the unloading roll.
working principle 
When the paper roll is advanced onto the platform in the upper position, the platform unloads the paper roll to the intermediate position and then onto the floor, and the paper roll rolls off the platform. For safety reasons, the platform will not automatically unload paper onto the floor unless it is moved by the operator from the intermediate position to the unloading position. The reel cannot be unloaded to the floor anyway before the new rewind.
