Tension Controller Constant Tension Control Principle

Tension controller constant tension control principle: it is measured by two tension detectors to the actual target tension (ie measuring tension), compared with the artificially set the required working tension (ie set tension), if two comparisons When the tension is equal. The tension controller does not adjust the output ratio, and when the two comparison tensions are not equal, the tension controller will judge that the measured tension is greater than or less than the set tension and correspondingly decrease or increase the output ratio, thereby making the measured tension and the set tension Maintain dynamic balance to achieve constant tension.

The automatic tension controller maintains the constant tension in the automatic working mode by comparing the measured tension with the set tension and adjusting the output ratio according to the tension difference. If the detected material is in the stop state, the tension controller cannot detect the actual The measured tension during operation, and the measured tension at this time will be smaller than the actual running tension. If the tension controller considers that the measured tension is less than the set tension and increases the output ratio, the tension will be caused in the next run. Big.

Therefore, the automatic tension controller pauses the adjustment of the output ratio if the pulse signal of the Hall switch is not received within 1 second in the automatic mode. At the same time, the auto mode indicator flashes to indicate that the controller is in the pause state. In fact, the tension controller has a dual-position retractable roll control function, and the user can set the reversal output according to the machine characteristics. The purpose of setting this proportional value is to make the controller re-assign the output proportional value of the working shaft when the two transmission shafts are mutually converted, so that the tension of the working shaft is as close as possible to the set tension, so that the tension controller reduces the shaft change.
