[0035] Referring to Figure 4 - Figure 5The height adjusting assembly 6 comprises a rotating rod 601, half gears 602 are respectively installed at both ends of the rotating rod 601, inner tooth plates 603 are arranged on the outer sides of the half gears 602, and the half gears 602 and the inner tooth plates 603 are in power transmission through meshing, so that the inner tooth plates 603 can also slide synchronously when the rotating rod 601 rotates, and the inner tooth plates 603 slide in the portal frame 4. In order to ensure the stable adjustment of the cutting mechanism 5, the bottom of the inner tooth plate 603 in the height adjusting assembly 6 is fixedly connected with the top of the sliding block 43, and the sliding block 43 is fixed at both ends of the cross beam 41. The sliding block 43 is driven to slide in the sliding groove 606 opened at the top of the portal frame 4 by the inner tooth plate 603, so that the cross beam 41 can accurately move in the sliding groove 606, and the cutting height is adjusted. The end of the rotating rod 601 is driven by a driving motor 604, and a mounting bracket 605 is arranged on the outer side of the motor.

Due to the design of the half gear 602, the lifting action of the inner tooth plate 603 can be realized.

[0036] With reference to Figure 1 Before the cutting mechanism 5 cuts the leather, the air cylinders 702 on both sides are started to pull down the pressing plate 701 located directly above the conveying belt 1, effectively clamping and stabilizing the leather, preventing the leather from moving during cutting and affecting the cutting quality.

[0037] With reference to Figure 2 - Figure 3 The smoothing assembly 9 comprises two mounting plates 901, which are respectively fixedly connected to the support structures on both sides of the top of the conveying belt 1. An arc-shaped groove 902 is formed in the inside of each mounting plate 901, and a spring 903 is installed in the arc-shaped groove 902. The spring 903 provides the necessary pressure to enable the entire smoothing assembly 9 to work stably. A scraper 904 is installed between the two mounting plates 901, and a central rotating shaft 906 is arranged in the inside of the scraper 904. The central rotating shaft 906 is rotatably connected to the insides of the two mounting plates 901. An adjusting rod 905 is arranged away from the central position of the scraper 904, and is slidably connected between the two arc-shaped grooves 902. The adjusting rod 905 is acted on by the spring 903 in the inside, and the pressure and height of the scraper 904 can be accurately adjusted through the adjusting rod 905 to adapt to leathers of different thicknesses or materials. The outer side of the adjusting rod 905 is fixedly connected with the end of the spring 903, and the elastic action of the spring 903 ensures that the adjusting rod 905 always maintains a certain pressure in contact with the scraper 904, helping to achieve a continuous smoothing effect.

[0038] Working principle: the skin material on the feeding mechanism 2 is unfolded, and the conveyor belt 1 sends the skin material to the cutting area. The skin material enters the deviation rectifying structure 8 for position adjustment, and then passes through the flattening assembly 9 for surface flattening. The scraper 904 in the flattening assembly 9 rotates through the center rotating shaft 906. Under the action of the spring 903 inside the adjusting rod 905 and the arc-shaped groove 902, the end of the scraper 904 is always in abutment with the top of the skin material. Before the cutting mechanism 5 works, the skin material is fixed through the pressing plate 701. The cutting mechanism 5 is slidingly installed below the cross beam 41 and can cut the skin material along the cross beam 41. The cutting mechanism 5 can be adjusted in height through the height adjusting assembly 6. The driving motor 604 drives the rotating rod 601 to rotate the half gears 602 at both ends, thereby driving the inner toothed plate 603 to slide. The inner toothed plate 603 drives the sliding block 43 to move up and down, thereby driving the cross beam 41 and finally changing the cutting height of the cutting mechanism 5. The overall system is controlled through the control box 42. The laser range finder arranged at the bottom of the cutting mechanism 5 can monitor the distance between the cutting mechanism 5 and the skin material in real time. After cutting, the waste is treated through the waste winding mechanism 3.
