Pe Film Rewinding Machine

Rewinding Machine operating procedures - Start thread
1The main operator passes the inspection to confirm that the paper core and the size of the paper cut are correct.
The power-on signal informs the operator to prepare the paper. Open the paper feed roller, blower system, and paper positioning system before threading.
2. Start the rewinding machine and crawl the car at a speed of 15 meters.
3. The base paper is torn or folded into a triangle and sent to the platen roller to be delivered by the platen roller.
The paper is fed to the bottom knife roll and pressed against the horizontal roller.
4. The paper web is drawn flat and the paper trimming is aligned with the paper core and the port.
Introduce the paper edge fan to inform the main operation to stop. At this time, check the trimming situation and adjust it in time.
5. Use a piece of tape to match the paper web to the paper core, and then remove the letter immediately after sticking.
No. To inform the main operation, press the platen roller button to press the platen roller against the paper core, and start the roll paper.

2 rear bottom roller

The platen roller device consists of a combination of devices that can be combined. The platen roller is supported by bearings on the platen beam beam.
The movable beam is fixed to the frame. The movement of the platen roller beam moves with the hydraulic cylinder attached to the beam. The platen roller is decoupled from the hydraulic cylinder during the rewinding process. The platen roller also includes a pressure sensor to measure the pressure between the platen roller and the frame.
The platen roller has a position measuring device for providing a position about the platen roller and the diameter of the paper roll. Based on the above information, the hydraulic cylinder moves in accordance with the separation design curve as the diameter of the paper roll continues to increase. The hydraulic cylinder is equipped with a hydraulic hose rupture protection valve to prevent the paper roll from suddenly falling when the hose is damaged.
working principle 
The platen roller provides additional load to the paper roll at the beginning of the rewinding. At a later stage of the rewind, the pressure is released. In the final stage, the platen roller ensures that the paper roll is in place.
During the threading and changing process, the platen roller is raised to the rear of the safety lock at the top position. The safety lock prevents the platen roller from suddenly falling when the device malfunctions. The platen roller is automatically decompressed when the platen roller is lowered to the core or the base. If the lowering control is terminated before decompression, the platen roller will be activated and the platen roller will be raised to the upper position.
During the rewinding process, the contact surface between the platen roller and the paper core must be carefully observed. If the platen roller is very close to the core, special care must be taken during the rewinding process. If the core starts to vibrate, the speed must be lowered immediately. There is a vibration indicator on the pressing roller beam to facilitate speed reduction in that case.

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.
