The middle part of the bottom plate 1 is fixedly installed with an upper air blowing plate 6 and a lower air blowing plate 9 through two support columns 8. The upper air blowing plate 6 and the lower air blowing plate 9 are connected with a fan 10. A plurality of nozzles 16 are evenly installed on the inner sides of the upper air blowing plate 6 and the lower air blowing plate 9 respectively. In the present utility model, an upper air blowing plate 6 and a lower air blowing plate 9 are installed in the middle part of the bottom plate 1, and a plurality of nozzles 16 are evenly installed on the inner sides of the upper air blowing plate 6 and the lower air blowing plate 9 respectively. When the fan 10 works, the nozzles 16 on the inner sides of the upper air blowing plate 6 and the lower air blowing plate 9 evenly spray out air, taking away the heat on the top and bottom surfaces of the aluminum-plated pre-coated film, achieving multi-point and uniform cooling of the aluminum-plated pre-coated film, and enabling the production quality of the aluminum-plated pre-coated film to meet the specified requirements.

[0021] A plurality of bases 2 are fixedly installed on the bottom surface of the bottom plate 1. The plurality of bases 2 are used to support the bottom plate 1, realizing the stable operation of the cooling device for preparing the aluminum-plated pre-coated film.

[0022] The guiding device 7 includes two fixed plates 701. An upper guiding shaft 702 and a lower guiding shaft 703 are rotatably installed between the two fixed plates 701. The upper guiding shaft 702 and the lower guiding shaft 703 rotate between the two fixed plates 701, and are used to guide the correct movement of the aluminum-plated pre-coated film.

[0023] One end of the bottom plate 1 is fixedly installed with a first support plate 12. The upper part of the outer side of the first support plate 12 is fixedly installed with a first motor 13. The first motor 13 rotatably installs the input shaft 3. When the first motor 13 rotates, it is used for the rotation of the input shaft 3, realizing the movement of the aluminum-plated pre-coated film towards the cooling part.

[0024] The other end of the bottom plate 1 is fixedly installed with a second support plate 15. The upper part of the outer side of the second support plate 15 is fixedly installed with a second motor 14. The second motor 14 rotates the output shaft 4.
