Rewinding Machine safety operation guide -
Third, the rewinding machine opening and closing operation sequence:
1. Start the rewinding machine and the paper edge blower motor to put the speed to the crawling speed. Tearing the web
Into one. The paper edge is wound into a roller according to the specified path, and the round paper web must be straightened. Loosen and tightly adjust, press the switch and the paper core tube to stick the tape. Stick the paper web to the paper core tube and start crawling. At the same time, the end of the paper roll is flat. The paper can not be wrinkled or discounted to ensure the quality of the rewinding. When the paper has broken ends, the joints are operated, the broken ends are connected and the joint quality is ensured.

Belt rewinding machine design and working principle ---
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.
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.
