[0021] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0022] Reference Figure 1 , Figure 2 and Figure 3 As shown, a plastic film slicer with high cutting accuracy comprises a base 1, two brackets 13 are fixedly connected at the upper edge of the base 1, a support plate 14 is fixedly connected to the upper end of the bracket 13, a hydraulic cylinder 15 is fixedly installed at the upper end of the support plate 14, an output end of the hydraulic cylinder 15 passes through the upper end of the support plate 14 and is fixedly connected to a lifting plate 16, a cutting knife 21 is fixedly connected to the middle of the lower end of the lifting plate 16, a plurality of springs 17 are fixedly connected at the lower edge of the lifting plate 16, two pressing blocks 18 are fixedly connected to the lower end of the spring 17, and the two pressing blocks 18 are located at The front and rear sides of the cutting knife 21, and the initial position of the pressing block 18 is located at the lower end of the cutting knife 21. When cutting, the hydraulic cylinder 15 drives the lifting plate 16 to descend, thereby driving the pressing block 18 and the cutting knife 21 to descend, so that the pressing block 18 is pressed on the surface of the film to avoid the film from shifting during the cutting process, making the cutting uneven, thereby affecting the cutting accuracy of the film. A slide groove 2 is opened at the upper end of the base 1, and an electric push rod 5 is fixedly installed at the front end of the slide groove 2. The output end of the electric push rod 5 is fixedly connected to a slider 3, and the slider 3 is slidably connected to the inside of the slide groove 2.
[0023] The upper end of the slider 3 is fixedly connected to a pad 6, the upper end of the pad 6 is fixedly connected to two guide rods 8, the upper end of the guide rod 8 is fixedly connected to a fixed plate 10, the upper end of the fixed plate 10 is threadedly connected to a threaded rod 12, one end of the threaded rod 12 passes through the upper end of the fixed plate 10 and is rotatably connected to a bearing seat 11, the outer surface of the guide rod 8 is slidably connected to a pressure plate 9, the upper end of the pressure plate 9 is fixedly connected to the lower end of the bearing seat 11, and one end of the film can be fixed by placing one end of the film on the pad 6 and rotating the threaded rod 12 to push the pressure plate 9 to press on the upper end of the film.
[0024] A pointer 7 is fixedly connected to the left side of the pad 6, and a scale line 4 is set on the left side of the upper end of the base 1. The initial position of the pointer 7 points to the zero scale of the scale line 4, and the position of the cutting knife 21 is flush with the position of the zero scale.

At this time, the position where the pointer 7 points to the scale line 4 is the length of the cut film. After the film is pulled out and cut to a certain length, the lifting plate 16 is driven down by the hydraulic cylinder 15, thereby driving the pressure block 18 and the cutting knife 21 to descend. The pressure block 18 first contacts the plastic film to press and fix it, and then the lifting plate 16 continues to descend. At this time, the spring 17 is gradually compressed, so that the cutting knife 21 contacts the plastic film for cutting.
