Self-adjusting insulating tape wrapping constant-tension control device

The invention provides a self-adjusting insulating tape wrapping constant-tension control device which can resolve the problem that tension of an existing insulating tape wrapping constant-tension control device cannot be adjusted in real time to guarantee wrapping quality. The self-adjusting insulating tape wrapping constant-tension control device comprises a machine base, an insulating paper disc and a photoelectric paper breaking switch, wherein the insulating paper disc is installed on the machine base through a bearing, and a paper guiding roller is installed on a position, located at the upper end of the paper out side of the insulation paper disc, of the machine base. The self-adjusting insulating tape wrapping constant-tension control device is characterized by comprising a rotating block, a servo torque motor, a tension sensing device and a control center, wherein the insulating paper disc is connected with an output shaft of the servo torque motor through a transmission gear, the tension sensing device is arranged on a position, on the paper out side of the insulating paper disc, of the machine base, the rotating block is vertically installed on the tension sensing device, the two vertical ends of the rotating block are also provided with paper guiding rollers, the photoelectric paper breaking switch is installed on the lower side of the paper guiding roller at the lower vertical end of the rotating block, and the servo torque motor, the tension sensing device and the photoelectric paper breaking switch are connected with the control center respectively in an electronic control mode.
