At this time, the first motor 201 is started, and the first motor 201 drives the sliced ​​film to rotate 360 ​​degrees. At the same time, the cutting disk 207 operates, so that the edge of the film can be cut into a circle. The first motor 201 drives the sliced ​​film to rotate at a small angle, so that it can be cut into an arc edge.

[0027] In addition, it should be noted that when cutting circular edges or arc edges, it is necessary to start the hydraulic cylinder 5 to drive the lifting plate 501 down to facilitate the waste to be swept into the leakage groove 6. The shape of the lifting plate 501 is set to be rectangular, and a circular empty groove is opened inside it to match the shape of the turntable 202.

[0028] like Figure 4 As shown, further, the driving component 3 includes a support column 301, a hydraulic rod 303 and a limit rod 307; the two support columns 301 are fixedly connected to the base 1, and grooves 302 are provided in the two support columns 301; the two hydraulic rods 303 are respectively fixedly connected to the two support columns 301, and the driving ends of the two hydraulic rods 303 extend into the grooves 302 and are fixedly connected to the lifting block 304, and one side of the lifting block 304 is fixedly connected to the fourth motor 305, and the driving end of the fourth motor 305 passes through the lifting block 304 and is fixedly connected to the screw 306, the moving box 203 is threadedly connected to the outside of the screw 306, and the two limit rods 307 pass through the moving box 203.

[0029] During specific implementation, the fourth motor 305 is started, and the fourth motor 305 drives the screw 306 to rotate, thereby driving the moving box 203 to move under the limit of the limit rod 307, and then the two groups of hydraulic rods 303 are started, and the two groups of hydraulic rods 303 drive the lifting block 304 to move up and down, that is, drive the cutting disk 207 to move up and down, that is, drive the cutting disk 207 to move to the position where edge cutting is required, so as to cut the edge of the film.

[0035] In specific implementation, the film is first passed through two sets of driving rollers 402 and driven rollers 403, and the fifth motor 401 is started. The fifth motor 401 drives the driving roller 402 to rotate. Since the film is clamped by the driving roller 402 and the driven roller 403, the film can be driven to move.

[0036] In addition, it should be noted that the two first motors 201 are driven synchronously, and the driven roller 403 can be raised and lowered so as to clamp films of different thicknesses. This is a prior art and will not be described in detail.

[0037] Working principle: First, pass the film through the two sets of driving rollers 402 and the driven rollers 403, start the four hydraulic cylinders 5, and drive the lifting plate 501 to rise to a position flush with the turntable 202 to support the film trimming, then start the fifth motor 401 to drive the film to move, at the same time, start the fourth motor 305, the fourth motor 305 drives the screw 306 to rotate, and then drives the moving box 203 to move under the limit of the limit rod 307, then start the two sets of hydraulic rods 303, the two sets of hydraulic rods 303 drive the lifting block 304 to move up and down, that is, drive the cutting disk 207 to move up and down, that is, drive the cutting disk 207 to move to the position where the trimming is required, and cut the film. Edges, when it is necessary to cut circular or arc-shaped edges, the film must first be divided into multiple discontinuous pieces, and then the second motor 204 is started.

At the same time, the cutting disk 207 operates to cut the edge of the film into a circle. The first motor 201 drives the sliced ​​film to rotate at a small angle, so that it can be cut into an arc-shaped edge. The generated waste will fall into the waste box 601 through the leakage groove 6 and will be cleared after it is full.
