Two brackets 10 jointly rotatably connect a second idler roller 11, and the height of each first idler roller 5 and the second idler roller 11 is greater than the height of the lower mold 6. When the plastic sheet is transported through the plurality of first idler rollers 5 and the second idler roller 11, the resistance and the friction between it and the lower mold 6 are reduced;

[0024] Two brackets 10 are symmetrically installed on the top surface of the base 1. A plurality of rotating rollers 12 are jointly rotatably connected to the two brackets 10. The two brackets 10 adjust the height of the rotating roller 12 located at the top through an adjusting mechanism.

A motor 16 is fixedly installed on the outside of one of the square plates, and the output shaft of the motor 16 penetrates the square plate and is connected to the corresponding rotating roller 12;

[0025] It should be noted that the rotation roller 12 at the top can be driven by the threaded rod 17 to adjust the height, so as to facilitate the tensioning of the cleaning cloth 15 by the two rotation rollers 12, and facilitate the driving of the cleaning cloth 15 to rotate by the motor 16;

[0026] The rotation roller 12 at the bottom is elastically connected to the bracket 10. A through groove is provided in each bracket 10, and a spring telescopic rod 13 is fixedly installed on the top wall of each through groove.

Then, the external driving source drives the winding roller 3 to rotate, which can drive the plastic sheet to be automatically fed. At the same time, the electric telescopic rod 8 and the vacuum forming machine body 2 can be started to vacuum form the plastic sheet;

[0029] At the same time, during the movement of the plastic sheet, the rotation roller 12 and the second supporting roller 11 can be closely attached through the arrangement of a plurality of spring telescopic rods 13 and bearings 14, so as to clean the dust on the plastic sheet by the cleaning cloth 15. At the same time, by turning the threaded rod 17 to drive the upper rotation roller 12 to adjust the height, the cleaning cloth 15 is tensioned. Then, by starting the motor 16 to drive the cleaning cloth 15 to rotate, during the rotation, the scraper 21 cleans the dust on the cleaning cloth 15, and at the same time, the cleaning cloth 15 is wetted by the sponge 20, so as to increase its dust absorption effect and make the cleaning more thorough.
