Rewinding Machine safety operation guide -
Eight, pay attention to safety matters:
1. When unloading the paper roll, pay attention to whether there is someone in front.
2. Pay special attention to safety when using the paper feed roller
3. It is strictly forbidden to pass over the top of the head when lifting the paper roll, and check the firmness.

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;

9 small paper rolls launched
The small paper roll ejecting device is used for those paper rolls that are too small for the paper feed roller. The small paper roll ejecting device is mounted on the paper feed roller. It relies on hydraulic pressure to move. The minimum diameter that the small paper roll exit can be pushed out is 200 mm (7.9 in).
10 paper cutter construction
The paper cutter is a zigzag blade, which cuts the slit webs during roll ejection. The paper cutter rises from the paper roll to the paper cutting position. The movement of the paper cutter is done by a lever driven by a hydraulic cylinder.
The paper roll is pressed against the raised paper cutting blade by the ejector pin and cut.
11 core positioning pin
The end of the core loader is a paper core locating pin attached to the rewinder frame. The paper core positioning pin includes a metal plate and a frame. The scale on the core locating pin shows the position of the locating pin. The paper core locating pin holds the paper core in the correct position on the core loader only by the edge of the slitter. The core positioning pin is placed in close proximity to the slit and is locked in that position by the locking arm.
