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.

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 safety operation guide - 

Third, the rewinding machine opening and closing operation sequence:
1. Start the rewinding machine and the paper edge blower motor to put the speed to the crawling speed. Tearing the web
Into one. The paper edge is wound into a roller according to the specified path, and the round paper web must be straightened. Loosen and tightly adjust, press the switch and the paper core tube to stick the tape. Stick the paper web to the paper core tube and start crawling. At the same time, the end of the paper roll is flat. The paper can not be wrinkled or discounted to ensure the quality of the rewinding. When the paper has broken ends, the joints are operated, the broken ends are connected and the joint quality is ensured.
