Rewinding Machine Structure - Pressure Mechanism
1, the platen roller
First, in the rewinder system, the platen roller has a significant impact on the tightness control of the paper roll. Among them, the pressure adjusting mechanism plays a role of keeping the pressure of the paper roll and the supporting roll nip constant, and the main purpose is to prevent the paper roll from slipping or being wound too tight at the beginning of the work.
The paper roll is slippery because the paper roll is too light and the take-up is too tight because the pressure is too high until the rewinding to the late stage. In the modern rewinder system, the platen roller is automatically controlled so that additional weight can be applied to the paper web. The force.
2. Hydraulic (air pressure) suspension mechanism
Under normal circumstances, the adjustable pressure actuators use hydraulic suspension scale mechanism. We install a potentiometer attached to the platen roller to display the diameter of the finished paper roll, which is sent through the potentiometer. The signal is passed to the pressure program control unit,
To calculate the pressure, so that the oil pressure in the scale can be changed, thus achieving the pressure control of the platen roller.

Seventh, production operations and quality control during the rewinding process:
7. The tape must be kept in accordance with the regulations. When the head is reconnected, the tape outside the broken head must be
Take out in time, it is forbidden to mix the tape into the damaged paper, pay attention to the rewinding equipment, the running condition, find the problem and stop the contact and deal with it in time to prevent the quality of the rewinding.
8. The paper machine has a long downtime and works well with the paper machine.

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.
