Rewinding Machine operation safety regulations -
Fourth, other requirements in the production process：
5. When an abnormality or malfunction occurs in the production process, the machine must be turned off and checked and repaired. If the abnormality or failure is not handled, the workshop supervisor should be reported in time;
6. The perforation line must be inspected every half hour during the production process. If the perforation line is unqualified, it must be shut down immediately;
7. Every paper change must be weighed twice in the production process. If the weight of the original paper is quantitative, the texture and elongation are unstable, the number of knots should be adjusted at any time, the pressure of the riding stick should be adjusted, and the gearbox should be adjusted. The paper is elastically adjusted to meet the product diameter requirements, and the weighing is tracked to see if the weight of the product meets the standard.
8, at any time to patrol the quality of the product.

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.

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.
