[0028] In this embodiment, a slide groove 203 is provided on both sides of the bracket 2, and a slide rod 703 is provided on both sides of the knife seat 7. The two slide rods 703 are threadedly connected to the screw rod 301 through the slide groove 203. Figure 2 As shown, the knife seat 7 is lifted up and down along the slide slot 203 by the slide rods 703 on both sides under the action of the screw rod 301 to complete the shearing.

[0029] In this embodiment, two limit plates 1 are provided with a second slide groove 402, and the front ends of the two limit plates 1 are provided with a hole 401, which is communicated with the second slide groove 402. Slide rods 1 501 are installed on both sides of the shearing platform 1 5, and are movably connected with the second slide groove 402. The two slide rods 1 501 are threadedly connected with a second screw rod 403, and the front ends of the two screw rods 403 are fixedly connected with a torsion plate 404 through the hole 401. Figure 1 and 6 As shown, the position of the shearing platform 1 5 can be adjusted by twisting the torsion plate 404 to drive the screw rod 2 403 to rotate, thereby changing the position of the slide rod 1 501 in the slide groove 2 402, thereby adjusting the position between the shearing platform 2 6.

[0030] In this embodiment, a plurality of mounting holes 701 for mounting the blade 8 are provided in the knife seat 7, a plurality of dampers 907 are provided in the opening 1 702, the front ends of the plurality of dampers 907 are fixed to the inner wall of the opening 1 702, and the rear ends are fixed to the slide plate 901, the slide plate 901 is movably connected in the opening 1 702, the lower end of the slide plate 901 is movably fixedly connected to the limiting plate 2 9, a plurality of rollers 903 are movably connected in the limiting plate 2 9, a plurality of openings 2 902 are provided in the slide plate 901, the plurality of rollers 903 are movably installed in the openings 2 902, a rotating rod 904 for rotation is installed in the plurality of rollers 903, the surface of the rotating rod 904 is provided with a frosted surface for increasing friction, a plurality of rollers 903 are provided with straight rods 905 at the rear ends, and a connecting rod 906 is fixedly connected between the plurality of straight rods 905, such as Figure 3 , Figure 4 and Figure 5 As shown, the connecting rod 906 is used to rotate the angle of the roller 903. As shown in the figure, the two sides of the roller 903 are elliptical, and the arc is used to install the blade 8 in the front. The frosted surface of the rotating rod 904 can increase the friction of the roller 903 when it rotates, so as to improve the stability of the position of the roller 903 after rotation. The damper 907 arranged at the front end of the slide plate 901 is used to improve the stability of the structure.

[0031] Working principle: After a certain period of shearing, the shearing machine needs to adjust the blade gap. First, push the connecting rod 906 on the back of the blade holder 7 downward. At this time, with the downward thrust of the connecting rod 906, the side of the roller 903 close to the blade 8 is pushed upward. Figure 3As shown, when it is lifted up, the arc at the front end of the roller 903 squeezes the blade 8, thereby adjusting the gap of the blade 8, making the gap of the blade 8 smaller and tighter without affecting the cutting. In order to cooperate with the gap adjustment of the blade 8, the shearing platform 2 6 located below the blade 8 cooperates with the gap adjustment. The torsion plate 404 set at the front end of the screw rod 2 403 can drive the screw rod 2 403 to rotate and change the position of the slide rod 1 501 in the slide groove 2 402, thereby adjusting the position of the shearing platform 2 6.
