Mechanical torque limiting device for preventing equipment from being blocked and stuck

A mechanical torque limiting device for preventing blocking and clamping of equipment comprises a rotating screw supporting frame, the rotating screw supporting frame is fixed to an equipment shell, a rotating shaft is fixed to one end of the rotating screw supporting frame, a rotating screw is installed on the rotating shaft, a speed reducer anti-rotating arm is fixed to a corresponding speed reducer, and the rotating screw is sleeved with the speed reducer anti-rotating arm; a spring is sleeved on the rotating screw on one side of the speed reducer anti-rotating arm, and the other end of the spring is limited by a limiting piece; a sensor is installed on one side of the speed reducer anti-rotating arm in a right-facing mode, and when the speed reducer moves relatively due to material blocking and clamping, the speed reducer anti-rotating arm and the sensor are staggered. According to the mechanical torque limiting device for preventing the equipment from being blocked and stuck, the situation that the equip
