Rewinding Machine common fault - The platen roller does not move
1. Proportional valve is unstable. - Clean the proportional valve or replace the proportional valve to adjust the amplification signal.
2. Control failure - on-site debugging of the instrument.
Rewinding Machine operating procedures -
First, the boot process:
4. Press the gas up axis button to inflate the gas riser shaft;
5, adjust the position of the left and right correction sensor, so that the correction position is 50%, cancel the paper-like
6. Open the stop tension maintaining function;
Note: Before opening the tension, ensure that the product has no obvious relaxation;
7. Set the running tension and automatic running speed separately;
(1) The tension is set according to the characteristics of the product. The cigarette pack is generally about 45N, the most
Do not exceed 60N;
(2) The maximum running speed should not exceed 200m/min;
Rewinder mechanical structure and control process ---
Second, the main structure of the winder
2.1 Ejection Department
In the rewinder system, we installed the paper roll on the paper exit frame. In order to ensure that the width of the sides of the paper web is the same, we should be moving the seasoning when the paper roll is ejected. However, the paper roll in the new structure can be moved together with the paper exit frame, which ensures greater rigidity of the paper exit frame. In addition to manually moving the paper roll, we can also use the pneumatic, photoelectric device and electric method to adjust the axial movement of the paper exit frame, so that the cutting edge of the winder can be narrowed, and the manual adjustment can not be achieved. Requirements.
We have a coupling on the reel of the unwinding roll. When working, we can use a pneumatic device to connect the brake to the motor. We can know that when the high-speed winder is started, the required acceleration time from zero to 2000m/min can be completed within 50~60s, and the deceleration time required for braking is 40s. Or even shorter, so we need to consider the maximum diameter and the maximum braking speed of the paper-removing brake on the winder to reduce the paper loss of the paper-cut, or it will cause a lot of waste. In the selection of the brakes of the eject roll, we often use brakes for starting brakes, magnetic brakes and mechanical brakes. In the usual case, we use the combination of the brake motor and other brake devices. When we press the paper, the paper roll started by the DC motor can enter the acceleration and working state and can be operated by the braking of the DC motor. Control, the tension control of the paper web, in the case of emergency stop, we can use the DC motor and other brakes together to stop the paper roll at the fastest speed.
