When stretching the film left and right, control the two third electric cylinders 304 to extend. The two third electric cylinders 304 drive the second mounting bracket 305 and the roller 306 to move downward. At this time, under the extrusion of the roller 306 and the right conveying roller 101, the friction force when the film is conveyed to the left is increased, and the left and right stretching of the film can be realized at this time. When the two third electric cylinders 304 are damaged, control the two second electric cylinders 302 to contract. When the two second electric cylinders 302 expand and contract, they can drive the roller 306 to adjust the height, and the pressing of the film can also be realized. When stretching the film forward and backward, start the supply pump. At this time, the hot air flows out through the through holes 403. The hot air flowing out through the through holes 403 can expand the film forward and backward. Control the two fourth electric cylinders 502 to extend. At this time, the film can be pressed into an arc shape through the auxiliary seat 503. The arc-shaped film and the hot air flow through the through holes 403 can improve the forward and backward expansion effect of the film. Start the cold air supply pump. At this time, the cold air flow dissipated by the cooling tube 603 can cool and shape the film. During the use process, controlling the telescopic movement of the sixth electric cylinder 701 can adjust the height of the threaded tube 702. When the top of the threaded tube 702 contacts the bottom end surface of the first mounting bracket 303, the downward movement limit of the first mounting bracket 303 can be realized, avoiding damage to the film caused by the excessive downward movement distance of the roller 306. When the sixth electric cylinder 701 is damaged, the threaded tube 702 can be manually rotated to adjust the height of the threaded tube 702.
