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.
Four release and one rewinding machine operation program ---
Second, the machine starts
1. Press the warning button and delay for about 2 seconds. At the same time, the alarm sounds, and then press the start button to start the machine.
2. When the machine starts, fine-tune the discharge roller to ensure that the material is flush at the receiving roller. During the fine adjustment process, the gear is not rubbed against the periphery.
3. When the machine is running, no objects are allowed between the ultrasonic probe and the material axis. This will cause the machine to stop working.
Third, automatic acceleration
When the accelerator button is pressed and delayed for about 3 seconds, the machine automatically accelerates to the required maximum speed (set in the touch screen), and the deceleration button is pressed once during the acceleration process to automatically accelerate and stop.
