[0024] In the embodiment of the present application, when in use, the PVC film to be processed is placed on the placement plate 7, and then, by starting the cylinder 3, the cylinder 3 drives the fixed installation component 5 to move downward, and then drives the hot pressing plate 8 to move downward, thereby completing the film pressing operation. In the process of the fixed installation component 5 moving downward, the pressing block 13 moves downward to squeeze the rubber pad 68, thereby driving the slider 67 to move downward along the slide groove 62, and then drives the buffer spring 66 to move downward along the installation groove 63 to squeeze the sliding block 65. The sliding block 65 plays a certain buffering role on the downward pressure, effectively preventing the film from being broken by excessive impact, and at the same time improving the service life of the placement plate 7 and the hot pressing plate 8.
