Barrier Tape

Rewinding Machine common fault - The coil does not run or is broken
1. Winding tension controller is not open - Open winding tension controller switch
2, the speed of the governor is too low - increase the speed of the governor
3, did not press the reset button - press the reset button on the two tension controllers
4, the tension tension controller tension is too small - increase the winding tension controller output current
5, unwinding tension control tension is too large - reduce the unwinding tension controller output current
6, the running button is damaged - replace the run button
7, tension controller failure - contact the manufacturer
8, governor failure - contact the manufacturer

Automatic rewinding machine speed ratio adjustment method ---

4. Adjust the internal toothed chain and external chain of the main gearbox to make the transmission of the whole machine more stable. When the roll paper rewinding machine is running, it is controlled by the automatic acceleration and deceleration program to start and stop frequently, and the automatic trimming and sealing operation is completed. Therefore, the stability of the gearbox transmission ratio is high. By tightening its internal and external chains, the chain can be prevented from slipping and skipping, making the speed ratio more stable during frequent acceleration and deceleration. The tensioned upper chain of the toothed chain can be moved up and down by a tool of about 5 to 8 mm.

Belt rewinding machine design and working principle ---

rear bottom roller

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.
