Rewinding Machine common fault - Rolls are not collected
1. The original coil is not uniform - Finish the original coil to ensure that the original coil is neat
2, paper core size head - check the paper core
3, only start a short period of time - normal phenomenon,
4, bearing damage - bearing damage is often accompanied by abnormal noise, pay attention to check the bearing, found that the damage is replaced in time
5, shaft damage - contact the manufacturer
Four release and one rewinding machine operation program ---
6. Check if the power indicator on the outside of the tension control cabinet is lit.
7. In the touch screen, you need to input or rewrite the following parameters:
1 counting length is cleared (if it is necessary to re-measure the length);
2 automatic acceleration speed (refers to the speed we reach after the automatic acceleration of the machine after pressing the acceleration button delay)
3 Automatic acceleration time (refers to the time required for the machine to automatically accelerate from zero speed to the design of the highest machine speed. The shorter the time setting, the faster the acceleration.)
8. Tension control: Set the tension of each discharge motor in the touch screen. The discharge motor mainly provides a reverse torque, generates tension on the paper surface, keeps the paper web flat, and the speed control of the discharge motor is a process of gradually increasing speed, but the line speed remains unchanged.
9. Each console has its own power switch, which can be switched on and off as needed.
10. The forward and reverse running buttons are set on the console, and the user can select the running direction according to the needs.
Rewinder mechanical structure and control process ---
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.
