In addition, a heating component is provided in the lower pressing wheel 703, so that the edge of the PET film is heated and softened while being flattened, thereby improving the flattening quality. By arranging the first spring 710, the first spring 710 drives the moving block 712 to move downward, and then the moving block 712 drives the upper pressing wheel 709 to exert a certain pressure on the PET film, thereby improving the flattening quality.
