Adhesive Tape Automatic Rewinding Machine

Rewinding Machine structure - 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. But the paper roll in the new structure can move with the paper exit frame,
This ensures a greater rigidity of the 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.

Four release and one rewinding machine operation program ---

Fourth, normal shutdown and emergency stop
1. The emergency stop is faster than the normal stop speed. After the stop, the traction roller is automatically raised. The self-locking button is urgently deactivated. In the state of emergency stop, the machine cannot be started. We need to unlock the emergency stop before the machine can be started. . When the machine does not start (observe whether the start indicator is lit), we check the status of each emergency stop button.
2. When the discharge roller is about to release the material, it must be decelerated in advance. It is guaranteed that the speed of the material is just zero when it is finished.
3. Deflating Adhere the material on the receiving roller with tape, open the pressing shaft, lift the receiving roller, place it on a stable place, deflate the receiving roller, and pull out the receiving roller.

Rewinder mechanical structure and control process ---

Third, the rewinding machine control performance indicators
The rewinder is the last process in the papermaking process. The performance of the rewinder determines the quality of the finished paper roll. A complete rewinder must have the following properties:

3. Tension adjustment mechanism
It is generally believed that web tension control is one of the important factors affecting the tightness of the paper roll. The most important function of flattening the paper web during the rewinding process is the web tension, and the web tension must be kept stable before the paper can be avoided. The lateral movement of the web allows the rolled out finished paper roll to meet the requirements. However, the web tension is only affected when the finished paper roll is rolled up. Since we are using a double bottom roller lower paper rewinding machine, the paper web must pass through the back bottom roller to be wound on the paper roll. The roller will isolate most of the tension, and only a small amount of tension can be transferred to the finished paper roll, which means that if there is tension to control the hardness of the paper roll, if the hardness of the paper roll changes little, The tension will change a lot. The key factors affecting the hardness of the paper roll are the pressure of the platen roller and the torque difference between the front and rear bottom rollers. The effect of the web tension on the hardness of the paper roll is not great because it is not a critical factor. 4. Electric drive "flexible" start and proper speed program control The starting of the winder is of course smoother and better, so that the paper web can be prevented from being subjected to the impact of tension, and the breakage can be reduced and the paper roll can be improved. Rewind quality. In order to meet such requirements, we often add a given integrator to the speed and current of the speed regulation system. This is beneficial to the start of the winder. Through analysis, we can know that if the system is to start more smoothly, give The larger the time constant of the integrator, the better, so the integral time constant of a given integrator can be adjusted over a large range to suit the processing requirements.
From the above four points, we can see that the electronic control system must have adjustment skills to meet the rewinding process.
