Brief introduction and role of tension controller

Brief introduction of tension controller

1. Adjustment of the product tension manually or automatically so that the tension change can be effectively controlled is called tension controller. The tension controller is mainly used in the tension system in which the actuator is a magnetic powder clutch or magnetic powder brake, and there are three modes: manual semi-automatic, and automatic.

2. the manual tension controller is based on the change of the winding diameter of the winding tube, and then manually adjusts the excitation current of the magnetic powder clutch or magnetic powder brake on the controller, so as to ensure that the tension of the product is relatively constant.

3. automatic tension controller through the sensor for direct detection of tension, and according to the set target tension and the actually measured tension automatically adjust the clutch or brake excitation current to control the tension of the roll material, to achieve constant tension

4. application industry: paper, plastic, textile, cable, packaging, and other industries.

What is the role of the tension controller?

Usually in machine operation, in order to ensure the speed of the machine, often use the tension controller controls the speed of the machine operation. This control must be effective for any operating speed of the machine, including the acceleration, deceleration, and uniformity of the machine. Even in the case of an emergency stop, there should be the ability to ensure that the slitted material does not break.

The stability of the tension control is directly related to the quality of the slit product. If the tension is not enough, the raw materials in the operation of the drift, there will be slitting and rewinding the finished paper wrinkled phenomenon; if the tension is too large, the raw materials are easy to be pulled off, so that the slitting and rewinding of the finished paper after the increase of broken head.

The main function of the tension controller: is to achieve constant tension control of the web, or according to the process requirements, to achieve the taper control of the web tension. In general, the requirements of constant tension control more occasions; requirements of the taper control, generally applied in the winding occasions, such as the realization of the coil of the tight, loose outer ring, etc., so that the material is not easy to deformation after the roll-up.
