Under the elastic force of the two springs 33 at the lower end, the tension roller 12 at the lower end generates a downward reaction force on the reflective film, thereby realizing the self-tensioning of the primary tension of the reflective film. The principle of the reflective film passing through the tension roller 12 at the upper end is the same as this, and under the action of the upper and lower tension rollers 12, the tension demand of the reflective film in the transmission process is effectively guaranteed to be adaptively met, and then the guide clamp 46 provides a guiding effect for the reflective film in transmission. At the same time, the personnel realizes the operation of the motor 28 by controlling the switch group 17, and the output shaft of the motor 28 rotates to drive the driving wheel 19 to rotate, and the driving wheel 19 drives the driven wheel 10 to rotate through the transmission belt 3, so that the winding roller 11 rotates, thereby realizing the winding work of the reflective film.
