Rewinding Machine safety operation guide - 

First, prepare for work after taking over:
1. It is necessary to arrive at the post, check, and original record 15 minutes earlier. Comprehensive understanding of the above
The operation of a class of equipment, the quality of rewinding and safety.
2. Understand whether the previous class of paper is good; whether the class changes specifications, the weight and change
time. Check if the shift is cleared in the previous shift.
3, the middle and night shift rewinders must check whether the rewinding paper core tube and packaging materials are adequate.
4,Report the handover to the squad leader

Automatic rewinding machine speed ratio adjustment method ---

3. Adjust the curved shaft behind the punching knife. The curved shaft is finally stretched as a smooth transition axis before the web is wound up. The position of the position and the working arc size not only affect the smoothness of the paper web, but also affect the stability of the web transport. When the curved axis is too high, the paper web is scratched by the punching surface knife, and the jitter is large and the paper is easy to break. When the position is too low, the paper web is scraped to the low hole and the broken layer is easy to break. Generally, the height of the curved shaft position is adjusted so that when the paper web passes through the punching knife, the bottom layer is preferably 5~8 mm higher than the punching bottom knife, and the working arc of the curved shaft is as small as possible, and the paper can not wrinkle.

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.
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.
