Rewinding Machine common fault - The coil is not tight during operation
1. Unwinding tension controller is not open - Open unwinding tension controller switch
2, did not press the reset button - press the reset button on the two tension controllers
3, the unwinding tension controller tension is too small - increase the unwinding tension controller output current
4, tension controller failure - contact the manufacturer
Rewinding Machine operation safety regulations -
Fifth, machine maintenance and hygiene
1. After the production is completed, first adjust the governor to zero, close the program switch, and finally turn off the power of the control box;
2. Use the air duct to blow the inside and outside of the machine and the electric box, and do not place any debris such as tools in the machine and the electric box.
3. Regularly repair and maintain the rotating parts of the machine (add some amount of oil or butter)
4. The hygiene of the machine area must be cleaned.
5. The waste paper is sent to the pulping station of the designated paper mill. The original paper core is neatly stacked in the specified paper barrel stacking area according to the specifications. The leather tape, waste paper and waste paper core are placed in the designated stacking area.
6, with the machine repair to do the regular maintenance of the machine main maintenance work.

Second, the main structure of the winder
2.4 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 slips because the paper roll is too light, and the winding is too tight because the pressure is too high until the rewinding to the later stage. In the modern rewinder system, the platen roller is automatically controlled, so that the paper can be additionally applied. 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 transmitted to the pressure program control unit to calculate the pressure, so that the oil pressure in the suspension scale can be changed, thereby achieving pressure control of the platen roller.
