At the same time, the excess scraps will be conveyed to the recycling component 10 for recycling. Finally, the auxiliary component 9 will perform the final size calibration and deburring on the PVC film rewound on the driving roller 8, thereby completing the trimming of the PVC film, thereby effectively improving the product quality of the PVC film trimming and the trimming efficiency of the PVC film.

[0026] The first fixed plate 2 is provided with a groove 11 corresponding to the second pressing roller 7, and a slider 12 is slidably connected between the groove 11 and the second pressing roller 7. The upper surface of the slider 12 is fixedly connected with a telescopic spring 13. Through the arrangement of the telescopic spring 13 and the second pressing roller 7, when the driving roller 8 rewinds the PVC film after the trimming process, the second pressing roller 7 flattens the PVC film rolled on its surface, and as the PVC film rolled by the driving roller 8 becomes thicker, the second pressing roller 7 is pushed to slide upward through the slider 12 and compress the telescopic spring 13, so that the second pressing roller 7 flattens the PVC film rolled on the surface of the driving roller 8.

The upper surface of the placement block 97 is provided with a placement groove 98 adapted to the first cutting head 95. Through the setting of the placement groove 98, the first cutting head 95 can be stored and placed when the first cutting head 95 is not in use to cut the PVC film, thereby effectively preventing the first cutting head 95 from being dangerous to the staff when not in use, thereby improving the safety of the staff. A scale line is provided on the edge of the slide groove 91 corresponding to the upper surface of the workbench 1, and a pointer is fixedly connected to the guide block 96 at the scale line corresponding to the scale line.
