[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0047] like Figure 1 and 3As shown, this embodiment discloses a casing peeling machine, comprising a rotary sleeve 1, a sausage segment conveying device 3, and a casing cutting device 4. During implementation, the rotary sleeve 1 rotates along its central axis. A plurality of elastic pawls 2 are provided on the inner annular wall of the rotary sleeve 1. Each elastic pawl 2 gradually bends toward the central axis of the rotary sleeve 1 in the conveying direction, forming a clamping guide for the sausage segment 5 passing through the rotary sleeve 1. The sausage segment conveying device 3 is located on the feed side of the rotary sleeve 1 and conveys the segmented sausage segments 5 into the rotary sleeve 1. The casing cutting device 4 is located on the discharge side of the rotating sleeve 1. The casing cutting device 4 includes a knife holder 401. A vertically arranged knife rod 402 is provided in the knife holder 401. The knife rod 402 is movably connected to the knife holder 401. A blade 403 is provided at the lower end of the knife rod 402. The cutting direction of the blade 403 swings in the range of 0 to 90° with the conveying direction of the sausage segment 5 as the starting point. A tension spring 404 is provided at the upper end of the knife rod 402. One end of the tension spring 404 is connected to the knife rod 402, and the other end is connected to the knife holder 401.

[0048] The working principle of the present invention is as follows: The intestinal segment conveying device 3 conveys the segmented intestinal segment 5 into the rotating sleeve 1. Multiple elastic pawls 2 are arranged around the intestinal segment 5 and clamp the intestinal segment 5. During the rotation of the rotating sleeve 1, the elastic pawls 2 drive the intestinal segment 5 to rotate (the rotation direction of the intestinal segment 5 is opposite to the rotation direction of the casing during the molding process, that is, the casing at the node is loosened). In this way, through the combined action of the intestinal segment conveying device 3 and the rotating sleeve 1, the intestinal segment 5 is conveyed forward in a spiral shape. Then, under the action of the tension spring 404, the knife rod 402 drives the blade 403 to contact the casing outside the intestinal segment 5 and cut the casing. As the blade 403 contacts the intestinal segment 5, the intestinal segment 5 pushes the blade 403 to swing within a range of 0 to 90 degrees, starting from the conveying direction of the intestinal segment 5. The swing angle of the blade 403 is related to the conveying speed of the intestinal segment conveying device 3.

[0049] To control the blade to swing in the range of 0 to 90 degrees, Figure 3 As shown, in this embodiment, a blade block 401-1 is provided at the lower end of the blade holder 401, and the blade block 401-1 is close to the rotating sleeve 1. The blade rod 402 is cylindrical, and a handle block 402-1 is provided at the upper end of the blade rod 402. The outer end of the handle block 402-1 is away from the blade block 401-1, and the handle block 402-1 is connected to a tension spring 404. The lower end of the blade rod 402 is provided with a blade seat 402-2, which abuts against the blade block 401-1, and the blade 403 is mounted on the blade seat 402-2. When the blade seat 402-2 abuts against the blade block 401-1, the blade 403 forms a 90° angle with the conveying direction of the intestinal segment 5.

[0050] like Figures 4 to 6As shown, a pawl support ring 15 is nested in the rotating sleeve 1, and a spring top ball 1501 is provided on the outer ring wall of the pawl support ring 15. The spring top ball 1501 is embedded in the reserved positioning groove of the inner ring wall of the rotating sleeve 1, and each elastic pawl 2 is provided on the inner circular wall of the pawl support ring 15.

[0051] The rotating sleeve 1 and the pawl support ring 15 are detachably connected. In this embodiment, the inner circular wall of the rotating sleeve 1 and the outer circular wall of the pawl support ring 15 are polygons of the same size, and the rotating sleeve 1 and the pawl support ring 15 are snap-fitted and nested through the polygonal structure.

[0052] As a method for realizing the rotation of the rotating sleeve 1 around its own axis, in this embodiment, as Figures 7 to 9 As shown, a gear ring 101 is provided on the outer circumferential wall of the rotating sleeve 1, and the gear ring 101 meshes with the output end of the gear set 13. The gear set 13 and the rotating sleeve 1 are both rotatably connected in a gear box 1301. In this embodiment, the gear set 13 is a three-stage gear combination, and the gear box 1301 is a multi-piece stacked structure.

[0053] A rotating bearing 102 is mounted on the outer circumferential wall of the rotating sleeve 1. The outer ring of the rotating bearing 102 is assembled in the gear box 1301. A retaining ring 103 is provided at one end of the rotating sleeve 1 close to the guide bearing 802.

The arc-shaped bracket 1407 and the roller 1408 serve to lift and guide the intestinal segment.

[0056] When the casing cutting device 4 is working, the negative pressure fan generates negative pressure suction through the air hole 1405, adsorbing the cut casing on the drum 1404, and then the rotation of the drum 1404 transports the adsorbed casing to the negative pressure pipe 1403.

[0057] like Figure 10 、 12 As shown in Figures 15 and 15 , in this embodiment, the intestinal segment conveying device 3 includes two conveyor belt assemblies 301 symmetrically arranged up and down, and the area between the two conveyor belt assemblies 301 forms a conveying channel 302.
