[0027] The guide mechanism 8 includes a crossbeam 801, a threaded rod 802, a pressure block 803, and a limiting rod 804. The threaded rod 802 is spirally connected to the center of the crossbeam 801.

[0028] The guide and limiting structure composed of the guide mechanism 8 and the first support block 12 can guide and limit the stretched film.

[0029] The trimming mechanism 9 includes a slide 901, guide rods 902, positive and negative threaded rods 903, and trimming structure 904. Two guide rods 902 are symmetrically fixedly connected inside the slide 901. A positive and negative threaded rod 903 is arranged between the two guide rods 902. The two ends of the positive and negative threaded rods 903 are movably connected to two vertical plates 7 respectively. The positive and negative threads of the positive and negative threaded rods 903 are spirally connected to the trimming structure 904, and the two trimming structures 904 are symmetrically arranged.

[0030] The cutting structure 904 includes a sliding block 9041, a knife holder 9042, and a cutter 9043. The sliding block 9041 is connected to the positive and negative threaded rods 903 and is slidably connected to the two positive and negative threaded rods 903.

The two ends of the top plate 1101 are fixedly connected to the upper ends of the two bases 1 respectively. Two telescopic rods 1102 are fixedly installed below the top plate 1101, and the front ends of the two telescopic rods 1102 are fixedly connected to the pressure plate 1103.

[0034] Through the structural design of the linear motor 10, the second support block 13 and the tensioning mechanism 11, the extension and retraction of the pressure plate 1103 driven by the telescopic rod 1102 can tension the film on the second support block 13, so that the film remains flat during the cutting process and is easy to cut.

[0037] The working principle and usage process of this utility model are as follows: In specific use, the film roll is installed on the unwinding roller 2, then the film is wrapped around from below the guide roller 3, passes between the two heating rollers 4, and is heated by the two heating rollers 4. The film is then wrapped around from below the leftmost stretching roller 6 between the two fixed plates 5, and then from above the second stretching roller 6 from the left. Similarly, the film is finally wrapped around from below the rightmost stretching roller 6, and stretched by the multiple stretching rollers 6. The stretched film then passes between the first support block 12 and the pressure block 803, and then passes above the second support block 13 and the pressure plate 1103. The film passes through the bottom and is finally wound onto the take-up roller 14. Under the action of the first support block 12 and the pressure block 803, the film is guided and limited. The gap between the pressure block 803 and the first support block 12 can be adjusted by rotating the threaded rod 802 to accommodate films of different thicknesses. By adjusting the extension and retraction length of the pressure plate 1103, the tension of the film passing through the second support block 13 can be adjusted, making the film less prone to wrinkles during the cutting process and facilitating cutting. Furthermore, the edge trimming mechanism 9 can trim the edges of the film before cutting, ensuring the flatness of the edges after stretching and improving production quality.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
