Tensioning device for cable winding device

The tensioning device for the cable winding device comprises a machine body, an access door is arranged on the front face of the machine body, a driving mechanism is installed in the machine body, a coupler is installed at the output end of the driving mechanism through a torque sensor, and a driving shaft is arranged at the right end of the coupler. A cable reel and a locking ring are arranged on the outer side of the driving shaft, a supporting arm and a limiting shaft are arranged on the right side of the machine body, a swinging mechanism is arranged on the outer side of the limiting shaft, a control host is arranged in the machine body, and data collected by a torque sensor is transmitted into the control host. The tensioning device for the cable winding device has the advantage of automatically adjusting the tensioning force, and the problems that when a cable is wound on a cable reel, the weight of the cable reel is increased, the load of a motor becomes heavy, the winding diameter of the cable becomes
