Tension Control System And Its Adjustment

The printing tension control system is generally composed of magnetic powder brake, tension controller, magnetic powder clutch, gear reduction motor and other equipment. In the printing transmission system, two printing components are driven by the same driving shaft, and the paper feeding and winding components enable each component to achieve strict synchronous transmission, and the paper belt can basically maintain stable paper feeding force.

However, because of the difference between the printed materials and the process conditions, the transmission tension alone cannot keep the tension of the paper belt stable and consistent at all times. The following conditions can change the tape tension of the printing press:

1. Replace the new paper roll, so that the tension of the tape before and after the replacement is different.

2. The paper roll has obvious out-of-roundness, the radius changes synchronously during rotation, and the use of paper tape is unstable.

3. The change of printing speed will also change the tension of the tape. The greater the printing speed, the greater the tape tension, and the slower the printing speed, the smaller the tape tension.

4. Uneven tension of the paper roll will also affect the stability of the tension.

5. During the printing process, the paper roll slowly changes from large to small.
