Description

Technical Field

[0001] This utility model belongs to the technical field of enema equipment, specifically referring to an automatic unwinding device for natural sausage casings. Background Technology

[0002] The sausage is wrapped in a casing, and there are ties at both ends of the casing. Unwinding the natural casing is a key step in the sausage processing process. With the large-scale development of the sausage processing industry, the demand for automatic unwinding devices for natural casings is becoming increasingly urgent.

[0003] However, the existing natural casing rolling methods are mostly manual, which is not only inefficient, but also makes it difficult to ensure the stability and uniformity of casing rolling. During the later filling process, the minced meat is squeezed from the front end of the casing to the back, which can easily cause the casing to burst, affecting the sausage filling. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model proposes an automatic unwinding device for natural sausage casings. This device effectively solves the problem that the unwinding of natural sausage casings is mostly done manually, which is not only inefficient but also makes it difficult to ensure the stability and uniformity of the unwinding. In the later filling process, the minced meat is squeezed from the front end of the casing to the back, which can easily cause the casing to burst and affect the filling of sausages.

[0005] The technical solution adopted by this utility model is as follows: This utility model proposes an automatic unwinding device for natural sausage casings, including a sausage filling machine discharge pipe, a connecting seat, a filling structure, and a sausage casing unwinding structure. The connecting seat is threaded onto the sausage filling machine discharge pipe, the filling structure is fixedly mounted on the connecting seat, and the sausage casing unwinding structure passes through the filling structure. The filling structure includes a filling tube and a convex thread. The filling tube is located at the front end of the connecting seat, and the convex thread wraps around the front end of the filling tube.

[0006] Preferably, the casing unwinding structure includes a casing box, a concave thread, a casing groove, a threaded seat, a bevel, a sealing cap, and a rubber ring. The casing box is disposed through the filling tube. The concave thread is formed on the inner wall of the casing box. The casing groove is formed on the casing box. The threaded seat is disposed on the casing box and located at the opening end of the concave thread. The bevel is disposed on the inner side wall of the casing box. The sealing cap is threaded onto the threaded seat. The rubber ring is fixedly disposed inside the circular hole of the sealing cap.

[0007] To better achieve the desired effect of rolling sausage casings, the casing box is cylindrical with casing grooves on the cylindrical wall.

[0008] To achieve the purpose of unrolling sausage casings more quickly, a set of sausage casings is placed in the casing groove on the casing box, and the rubber ring is pressed against the inclined side to clamp one end of the sausage casing.

[0009] Furthermore, the sealing cap has a circular hole in the middle with a diameter larger than that of the filling tube.

[0010] To achieve the effect of fixing the end of the sausage casing, the rubber ring is made of rubber material and is circular in shape. The diameter of the upper edge of the inclined side is larger than the diameter of the inner ring of the rubber ring, and the diameter of the lower edge of the inclined side is smaller than the diameter of the inner ring of the rubber ring.

[0011] The beneficial effects of this utility model using the above structure are as follows: The automatic unwinding device for natural sausage casings proposed in this solution places the sausage casings in the casing groove on the casing box, which facilitates unwinding from back to front, so that the sausages can be filled from back to front, avoiding tearing the casings. At the same time, it can be placed separately, which facilitates feeding and improves production efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1 and Figure 2As shown, the present invention proposes an automatic unwinding device for natural sausage casings, including a sausage filling machine discharge pipe 1, a connecting seat 2, a filling structure 3, and a sausage casing unwinding structure 4. The connecting seat 2 is threaded onto the sausage filling machine discharge pipe 1, the filling structure 3 is fixedly mounted on the connecting seat 2, and the sausage casing unwinding structure 4 is inserted into the filling structure 3. The filling structure 3 includes a filling tube 5 and a protruding thread 6. The filling tube 5 is located at the front end of the connecting seat 2, and the protruding thread 6 is wrapped around the front end of the filling tube 5.

[0020] like Figure 1 , Figure 3 and Figure 4 As shown, the casing unwinding structure 4 includes a casing box 7, a concave thread 8, a casing groove 9, a threaded seat 10, a bevel 11, a sealing cap 12, and a rubber ring 13. The casing box 7 is inserted through the filling tube 5. The concave thread 8 is formed on the inner wall of the casing box 7. The casing groove 9 is formed on the casing box 7. The casing box 7 is cylindrical with the casing groove 9 on its cylindrical wall. A set of casings is placed in the casing groove 9 on the casing box 7. The threaded seat 10 is located on the casing box 7 and at the opening end of the concave thread 8. The bevel 11... 1. A sealing cap 12 is threaded onto a threaded seat 10 and installed on the inner wall of the casing box 7. The sealing cap 12 has a round hole in the middle with a diameter larger than that of the filling tube 5. A rubber ring 13 is fixed inside the round hole of the sealing cap 12. The rubber ring 13 is pressed against the inclined side 11 to hold one end of the casing. The rubber ring 13 is made of rubber and is circular. The diameter of the upper edge of the inclined side 11 is larger than that of the inner circle of the rubber ring 13, and the lower edge of the inclined side 11 is smaller than that of the inner circle of the rubber ring 13.

[0021] In practical use, first, insert the sausage casing into the casing groove 9 on the casing box 7, then leave the casing end at the bevel 11. Then, screw the sealing cap 12 onto the threaded seat 10 of the casing box 7 to tighten the sealing cap 12. At this time, the rubber ring 13 on the sealing cap 12 is pressed against the bevel 11, thereby squeezing and fixing the casing end. Then, insert the casing box 7 onto the filling tube 5, passing it through the concave thread 8 and the convex thread 6 on the casing box 7. Insert multiple sets of casing boxes 7 onto the filling tube 5 in sequence. Finally, screw the connecting seat 2 onto the discharge tube 1 of the sausage filling machine. First, screw the concave thread 8 on the first casing box 7 onto the convex thread 6 to fix it and prevent the casing box 7 from sliding. Then, screw the sealing cap 12 on the casing box 7 to loosen the rubber ring 13 from the squeezed casing. Then, pull the end of the casing and pull it out from the front outlet of the filling tube 5. Then, tie the rear end of the casing with a rope and control the sausage stuffer to squeeze out the meat paste, thereby filling the rear end of the casing. At this time, the casing is evenly discharged from the casing groove 9 on the casing box 7, thereby evenly filling the casing from back to front to avoid tearing. The above is the entire process of using the natural casing automatic unwinding device.
