[0023] Below the cooling roller 5, there are a housing 14, a U-shaped pipe 15, a cooling fan 16, and a circulation pump 17; the U-shaped pipe 15 is arranged inside the housing 14, the circulation pump 17 is connected to one of the universal pipe joints 13 and one end of the U-shaped pipe 15 through a pipeline, and the other end of the U-shaped pipe 15 is connected to the other universal pipe joint 13 through a pipeline; the cooling fan 16 is arranged on the housing 14, and the cooling fan 16 is connected to the housing 14 through a pipeline.

[0024] In this embodiment: One end of the plastic belt is wound around the collecting roller frame 2, and the plastic belt is alternately arranged below or above a plurality of high cooling frames 3 and low cooling frames 4, so that the upper surface and the lower surface of the plastic belt are respectively attached to the outer surfaces of multiple groups of cooling rollers 5. Cooling water is injected into the internal cooling cavity 7 of the cooling roller 5, and the cooling water exchanges heat with the cooling roller 5 to cool down the cooling roller 5. When the plastic belt is wound and moved, it is attached to the walls of multiple groups of cooling rollers 5, and the plastic belt exchanges heat with the cooling roller 5 to cool down the plastic belt.
