Four release and one rewinding machine operation program ---
6. Check if the power indicator on the outside of the tension control cabinet is lit.
7. In the touch screen, you need to input or rewrite the following parameters:
1 counting length is cleared (if it is necessary to re-measure the length);
2 automatic acceleration speed (refers to the speed we reach after the automatic acceleration of the machine after pressing the acceleration button delay)
3 Automatic acceleration time (refers to the time required for the machine to automatically accelerate from zero speed to the design of the highest machine speed. The shorter the time setting, the faster the acceleration.)
8. Tension control: Set the tension of each discharge motor in the touch screen. The discharge motor mainly provides a reverse torque, generates tension on the paper surface, keeps the paper web flat, and the speed control of the discharge motor is a process of gradually increasing speed, but the line speed remains unchanged.
9. Each console has its own power switch, which can be switched on and off as needed.
10. The forward and reverse running buttons are set on the console, and the user can select the running direction according to the needs.
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.

12Paper roll holder
When the paper roll is stopped, the paper roll is fixed at a certain position by the paper roll holder. The paper roll holder prevents slack and lateral movement of the paper roll. It is important to make a joint when making a customer roll. Roll holder on the take-up roll
The paper roll holder on the paper roll includes a spring-loaded plastic roll mounted on the paper cutter frame. When the paper cutter is in or on the middle position, the paper roll holder is placed against the surface of the rear bottom roller.
13 Automatic roll change
The rewinding device removes the paper roll from the winder.
The rewinding device cuts the sheet, pushes the paper roll onto the unloading station and fills in a new core for the rewinding.
The roll change can be started when the roll is decelerated. In the final stage of deceleration, the nipple guardrail and the platen roller rise to a high position. The unloader rises to the position where the paper roll is received. When the winder stops, the paper core clamp opens and rises to rise. The paper cutter is raised from between the paper rolls. The paper feed roller pushes the paper roll to the paper unloading station. At the same time, the paper cutter cuts the paper. The vacuum suction of the rear bottom roller sucks the cut sheet onto the roller. The core loader drops the new core onto the roll. The paper feed roller returns to its original position and the unloading table falls to the middle position. The paper core clip is lowered and closed. The platen roller and the nip guard are lowered. The winder crawls at a speed.
