Winding device

The invention discloses a winding device. The winding device comprises a rack, a winding shaft, a sensor and a controller; the winding shaft is used for winding a strip; the sensor is used for sensing a sensing signal indicating that an object to be detected enters the winding area in the circumferential direction of the axis of the winding shaft, the winding area is located between the sensor and the strip, and the winding area is located on the upstream of the strip in the winding direction of the strip wound by the winding shaft; the controller is electrically connected to the sensor and the winding shaft, and the controller controls the winding shaft to stop rotating according to the sensing signal; and determining a rolling-in central angle of the rolling-in area relative to the circle center of the rolling-in shaft according to the rolling-in outer diameter, the rolling-in speed and the response time parameter of the person, and further determining the rolling-in area so as to determine the position of
