The threaded rod 120 is screwed through the side of the support plate 110, and a knob 130 is provided at one end of the threaded rod 120, and the guide rod 140 movably passes through the support plate 110. The trimming assembly 20 includes a knife seat 210, a blade 220, a lower seat plate 230, an upper seat plate 240 and an elastic connection part 250. One side of the knife seat 210 is rotatably arranged with one end of the threaded rod 120 away from the knob 130, and one end of the guide rod 140 is fixedly connected to the knife seat 210 by welding. The blade 220 is installed below the knife seat 210, and a cutting notch 260 matching the blade 220 is provided on the lower seat plate 230 and the upper seat plate 240. The lower seat plate 230 is located below the knife seat 210 , the upper seat plate 240 is located between the lower seat plate 230 and the knife seat 210 , the elastic connection part 250 fixedly connects the knife seat 210 and the lower seat plate 230 , and the elastic connection part 250 elastically connects the lower seat plate 230 and the upper seat plate 240 .

[0027] When the film is rolled up, the edge of the film passes between the lower seat plate 230 and the upper seat plate 240 in the trimming assembly 20 and is cut by the blade 220. Under the elastic connection of the elastic connection part 250, the film moves in the gap between the lower seat plate 230 and the upper seat plate 240, so that the blade 220 is more stable when cutting the film, and has good cutting quality. The rotating knob 130 drives the threaded rod 120 to rotate, and the rotating threaded rod 120 simultaneously drives the knife seat 210 and the blade 220 to move along the axial direction of the threaded rod 120, that is, the width of the film cut by the blade 220 is adjusted, which has better applicability.

[0028] For further information, see Figure 1 and Figure 2 The support and adjustment assembly 10 further includes a stopper 150, which is fixed to the end of the guide rod 140 away from the knife seat 210; the stopper 150 is used to stop the guide rod 140 from sliding off the support plate 110. The support plate 110 is provided with a threaded hole 111 on the side thereof, which is threadedly engaged with the threaded rod 120. The support plate 110 is provided with a through hole 112 on the side thereof, and the guide rod 140 movably passes through the through hole 112.

[0029] In the above specific implementation, please refer to Figure 3 and Figure 4 The elastic connection part 250 includes a spring 251 and a vertical rod 252. The two ends of the vertical rod 252 are respectively fixedly connected to the lower seat plate 230 and the knife seat 210 by bolts, and the vertical rod 252 is movably inserted into the upper seat plate 240. The spring 251 is sleeved on the outside of the vertical rod 252 located between the knife seat 210 and the upper seat plate 240. The upper seat plate 240 is provided with a slot 241, and the vertical rod 252 is movably inserted into the slot 241. The spring 251 is used to elastically press the upper seat plate 240 and the lower seat plate 230.

[0030] Furthermore, upper rollers 280 are rotatably arranged at the bottom of the upper seat plate 240 on both sides of the blade 220, and lower rollers 270 are arranged above the lower seat plate 230 on both sides of the blade 220. The upper rollers 280 and the lower rollers 270 are arranged to reduce the friction force when the film moves between the upper seat plate 240 and the lower seat plate 230. A support block 290 fixedly connected to the lower seat plate 230 is arranged on the outer side of the lower roller 270, and the support block 290 is used to more stably support the film during the moving cutting.

[0031] The working principle of the film trimming device is as follows: when the film is rolled up, the edge of the film passes between the lower seat plate 230 and the upper seat plate 240 in the trimming assembly 20 and is cut by the blade 220. Under the elastic connection of the elastic connection part 250, the film moves in the gap between the lower seat plate 230 and the upper seat plate 240, so that the blade 220 is more stable when cutting the film, and has good cutting quality. The rotating knob 130 drives the threaded rod 120 to rotate, and the rotating threaded rod 120 simultaneously drives the knife seat 210 and the blade 220 to move along the axial direction of the threaded rod 120, that is, the width of the film cut by the blade 220 is adjusted, which has better applicability.

[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
