Automatic cable winding and unwinding device

The invention discloses an automatic cable winding and unwinding device which comprises a metal box body, a power module assembled in the metal box body, a main controller connected with the power module, a stepping motor controller connected with the main controller and the power module, and a stepping motor connected with the power module and the stepping motor controller. The speed reducer is connected with the output end of the stepping motor, the input module is connected with the main controller and the power module, the take-up and pay-off rack is located outside the metal box body and fixedly installed at the output end of the speed reducer, one end of the temperature sensor is welded to the input module, and the other end of the temperature sensor is fixed to the metal box body. The temperature sensor faces the take-up and pay-off rack and detects the temperature of the cable wound on the take-up and pay-off rack, the take-up and pay-off device can effectively solve the problem of length adjustment o
