[0016] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0017] This application discloses a cutting device for a skinning machine, such as... Figure 1 and Figure 2 As shown, the system includes a frame 1, multiple conveyor rollers 11 mounted on the top of the frame 1, a cutting frame 2 mounted on the top of the frame 1, a hydraulic cylinder 21 mounted on the top of the cutting frame 2, and a cutter 22 fixed to the piston rod of the hydraulic cylinder 21. The multiple conveyor rollers 11 are driven by a chain drive mechanism. A receiving plate 23 is fixed to the top of the frame 1 corresponding to the cutter 22. A limiting device 3 for limiting the top of the skin 9 is mounted on the cutting frame 2. The limiting device 3 includes two limiting frames 31 set above the skin 9. The bottom of each limiting frame 31 is rotatably connected to multiple limiting rollers 32 via bearings. A drive mechanism 4 for driving the two limiting frames 31 to move is mounted on the cutting frame 2. The multiple limiting rollers 32 facilitate limiting the top of the skin 9, thereby reducing the possibility of the skin 9 warping.

[0018] like Figure 1 and Figure 2 As shown, the drive mechanism 4 includes two lead screws 41 vertically rotatably connected to the top of the cutting frame 2 via bearings, and two guide rods 42 vertically fixed to the top of the cutting frame 2; two limiting frames 31 are threadedly connected to the two lead screws 41 respectively, and the two limiting frames 31 are vertically slidably connected to the two guide rods 42 respectively; a transmission assembly 5 for driving the two lead screws 41 to rotate is installed on the top of the cutting frame 2. When it is necessary to drive the limiting frames 31 to move, the two lead screws 41 are first driven to rotate through the transmission assembly 5, and the rotation of the two lead screws 41 can drive the limiting frames 31 to move; in summary, the drive mechanism 4 is designed to facilitate the movement of the limiting frames 31.

[0019] like Figure 1 and Figure 2As shown, the transmission assembly 5 includes a horizontal shaft 51 rotatably connected to the top of the cutting frame 2 via bearings and a handwheel 52 fixed to one end of the horizontal shaft 51. Two first bevel gears 53 are fixed to both ends of the horizontal shaft 51, and a second bevel gear 54 is fixed to the top of each lead screw 41. The two first bevel gears 53 mesh with the two second bevel gears 54 respectively. When it is necessary to drive the two lead screws 41 to rotate, the horizontal shaft 51 is first driven to rotate via the handwheel 52. The rotation of the horizontal shaft 51 drives the two first bevel gears 53 to rotate, which in turn drives the two second bevel gears 54 to rotate. The rotation of the two second bevel gears 54 then drives the two lead screws 41 to rotate. In summary, the transmission assembly 5 facilitates the rotation of the two lead screws 41.

[0020] like Figure 1 As shown, the cutting frame 2 is equipped with two sets of clamping mechanisms 6 for pressing the skin 9. Each clamping mechanism 6 includes a cylinder 61 vertically mounted on the top of the cutting frame 2 and a clamping plate 62 fixed to the piston rod of the cylinder 61. The clamping plate 62 is arranged corresponding to the conveying roller 11. The cylinder 61 and the clamping plate 62 facilitate the clamping of the skin 9, which in turn facilitates the cutting of the skin 9.

An insert plate 72 is fixedly connected to the top of the cutter 22, and the insert plate 72 is inserted into the slot 71. The insert plate 72 is bolted to the slot 71 by multiple bolts. A push plate 221 is fixedly connected to the top of the cutter 22. The insert plate 72 and slot 71 facilitate the installation of the cutter 22; the push plate 221 facilitates the upward pushing of the cutter 22.

[0022] like Figure 1 and Figure 3 As shown, a pre-fixing mechanism 8 for pre-fixing the insert plate 72 is installed on the side wall of the slot 71. The pre-fixing mechanism 8 includes a through hole 81 in the side wall of the slot 71, a connecting pipe 82 horizontally connected to the through hole 81, a pre-fixing block 83 slidably connected to the inner wall of the connecting pipe 82 in a horizontal direction, and a pull rod 84 fixed to one end of the pre-fixing block 83. A pre-positioning groove 85 is provided on one side of the insert plate 72. The end of the pre-fixing block 83 away from the pull rod 84 is provided with an inclined surface 86 and is inserted into the pre-positioning groove 85. The inclined surface 86 matches the side wall of the insert plate 72. A spring 87 is horizontally fixed to the end of the pre-fixing block 83 away from the insert plate 72. The end of the spring 87 away from the pre-fixing block 83 is fixed to the inner wall of one end of the connecting pipe 82. The pre-fixing block 83 and the pre-positioning groove 85 facilitate the pre-fixing of the insert plate 72.
