[0038] Refer to Figure 2, the distribution of the plurality of functional rollers 2 inside the first rack 1 makes the mesh belt 3 present a closed loop structure in space, so that the mesh belt 3 is driven in circulation under the cooperation of the plurality of functional rollers 2. The mesh belt 3 is made of high-performance nylon material, which has excellent wear resistance and tensile strength.

[0039] The plurality of functional rollers 2 includes a heating roller, a compression roller set 21 and a cooling roller 22 arranged in sequence along the transmission path of the rubber film raw material.
