[0002] In recent years, the research and development of transparent heat-absorbing and heat-insulating PVC protective films has become a hot topic in the industry. This film adds specific nanoparticles to the PVC film or adopts multi-layer co-extrusion technology to ensure high transparency while having excellent heat absorption and heat insulation properties. Transparent heat-absorbing and heat-insulating PVC protective films can not only effectively block the damage of ultraviolet rays and prevent material aging, but also significantly reduce heat transfer, improve human comfort and energy efficiency.

Traditional cooling methods often use air cooling or water cooling, but these methods cool the film slowly. At the same time, it is not convenient to guide the PVC film to the upper side of the cooling mechanism, which is inconvenient to use, resulting in low processing efficiency of PVC film.

[0024] In the plate utility model, the water inlet pipe 2 and the water outlet pipe 3 are connected to the external water supply equipment. When the cooling mechanism is not in use, the limit assembly makes the upper pressure plate 6 located at the uppermost stroke, and the lifting block 15 abuts against the lower side of the sleeve 11 to make the lower pressure plate 8 follow and lift up. At this time, the pressing roller 12 on the lower side of the long rod 7 is located on the upper side of the pressing roller 12 on the lower side of the short rod 10. At this time, the PVC film can be conveniently guided through it. The guide rollers 4 rotatably installed on the left and right sides are used to guide the PVC film to enter and leave the cooling tank 1 to ensure that the PVC The film remains stable during the cooling process to prevent it from twisting or folding. When the PVC film needs to be cooled, the limit assembly makes the upper pressure plate 6 located at the lowest stroke.
