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.

Third, the function introduction
1. The tension control of the eject roller consists of a tension sensor and an eject motor.
In the loop control loop, the paper take-off motor is an electric motor when unwinding, and is a brake generator during normal operation and parking.
2. The pressure control of the pressure roller is controlled by various sensors such as the take-up roller diameter detecting sensor.
Forming a closed-loop control system, there are three pre-made curves for different paper grades and different finished paper diameters for the operator to choose, and the actuator will be controlled according to these three different pressure curves.
3, between the two take-up bottom rollers, take the torque difference control method, corresponding to no
The same take-up diameter, the torque between the front and rear bottom rollers is distributed in different proportions.
