The raw materials are fed into the filling channel through the spiral feeding shaft, and the feeding is accurate, which makes the subsequent products uniform in thickness. The distance between the sensors ensures that the length of the products is consistent, which facilitates subsequent production and has high production efficiency. The above-mentioned related technologies have the following defects: In order to increase the efficiency of sausage filling in the factory, multi-station sausage filling is used. However, in multi-station sausage filling, it is common for workers to not change the casing in time. Before the new casing is installed, the meat will overflow and fall to the outside, causing waste. Therefore, a multi-station filling device and filling method for sausages are proposed. Summary of the Invention

[0004] To ensure that the extrusion of meat material stops promptly after the casing is filled, this invention provides a multi-station filling device and filling method for sausages.

[0005] The present invention provides a multi-station filling device for sausages, which adopts the following technical solution: it includes a filling pressure tank and a bottom box. The lower end of the filling pressure tank is connected to the upper surface of the bottom box. Multiple material passage blocks are installed on the side of the bottom box. The end of the material passage block near the bottom box is concave and communicates with the inside of the bottom box. A discharge pipe is fixed to the end of the material passage block away from the bottom box. An adjusting plate is provided between the discharge pipe and the material passage block. The material passage block is rotatably sleeved on the outer surface of the adjusting plate. A sausage casing connecting structure is slidably sleeved on the outer surface of the discharge pipe.

[0006] The regulating disc is equipped with a vertical shaft on one side of the outer circumference of the feeding block. A linkage rope is fixed to the other end of the vertical shaft. The other end of the linkage rope is fixed to the casing connection structure. A feeding hole is opened on the circumference of the regulating disc. The feeding hole intersects the axis of the regulating disc perpendicularly. The two ends of the feeding hole are connected to the inside of the discharge pipe and the concave structure of the feeding block, respectively.

[0007] Optionally, the discharge pipe is provided with fitting arc blocks on both the upper and lower sides of the end away from the material passage block. The two fitting arc blocks are detachably connected by bolts, and the material passage block is fixedly connected to the adjacent fitting arc block.

[0008] Optionally, the casing connection structure includes a variable diameter collar and multiple clamping plates. The outer diameter of the end of the variable diameter collar away from the material passage block is smaller than the outer diameter of the other end of the variable diameter collar. The clamping plates are located at the small diameter end of the variable diameter collar. The variable diameter collar is slidably sleeved on the outer surface of the discharge pipe. A threaded rod is fixed on the side of the clamping plate away from the axis of the variable diameter collar. An internal threaded ring is threaded onto the outer surface of the threaded rod. The internal threaded ring is rotatably connected to the variable diameter collar. The linkage rope is fixed to the variable diameter collar.

[0009] Optionally, the small diameter end of the variable diameter collar is rotatably sleeved with a meshing ring, and a small bevel gear is fixed at the end of the internal threaded ring away from the axis of the variable diameter collar, and the small bevel gear meshes with the meshing ring.

[0010] Optionally, an elastic bracket is fixed to one side of the feed block. The lower end of the elastic bracket and both sides of the axis of the adjusting disc are provided with slots. A round rod is provided inside the slot. The round rod is fixed to the end face of the adjusting disc. The upper and lower parts of the elastic bracket located in the slot are made of elastic material.

[0011] Optionally, a pressure spring is fixed to one end of the variable diameter collar near the material passage block, and the other end of the pressure spring is fixed to the discharge pipe, with the discharge pipe located on the inner ring side of the pressure spring.

[0012] Optionally, the material passage block is slidably inserted into the side of the bottom box. A tapered hole is provided on the connection surface between the bottom box and the material passage block. The end of the tapered hole away from the bottom box is the large diameter end. A tapered plug is inserted into the tapered hole. An elastic telescopic rod is fixed at one end of the tapered plug inside the bottom box. The other end of the elastic telescopic rod is fixed to the inner wall of the bottom box.

[0013] Optionally, the small-diameter end of the conical plug is located outside the bottom box, and a flat plate is fixedly inserted inside the recessed structure of the material passage block. The flat plate is in contact with the outer surface of the bottom box, and the central axis of the flat plate and the central axis of the conical plug are located in the same plane.

[0014] Optionally, a rope winding rod is provided in contact with the lower side of the linkage rope, and the rope winding rod is rotatably connected to the discharge pipe. The part of the linkage rope located on the left side of the rope winding rod is horizontal.

[0015] The multi-station filling method for grilled sausages includes the following steps:

[0016] S1. Place the sausage casing onto the surface of the discharge pipe and fix the end of the casing using the casing connection structure.

[0017] S2. The bottom box fills the discharge pipe with meat through the material passage holes in the material passage block and the regulating plate, and the discharge pipe fills the sausage casing with meat.

[0018] S3. As meat is gradually filled into the casing, the casing is gradually pulled out of the discharge pipe. The casing gradually tightens on the surface of the discharge pipe. As meat is continued to be filled into the casing, the casing gradually pulls the casing connecting structure to move.

[0019] S4. The casing connection structure uses a linkage rope to pull the vertical shaft and the adjusting plate to rotate. The adjusting plate causes the feed hole to be misaligned with the discharge pipe, so that when the casing is used up, the feeding into the discharge pipe stops. When filling sausages at multiple stations, the staff has enough time to change to new casings.

[0020] In summary, the present invention has the following beneficial technical effects:

[0021] This invention, by setting up components such as a linkage rope, a feeding hole, and an adjusting plate, allows the casing to gradually tighten as it is nearly empty. As the discharge pipe continues to fill the tightened casing with meat, the casing, under the thrust of the meat, moves the casing connecting structure. This structure, via the linkage rope, pulls the vertical shaft and adjusting plate to rotate. The adjusting plate causes the feeding hole to misalign with the discharge pipe, thus stopping the feeding of meat into the discharge pipe once the casing is used up. This provides sufficient time for workers to replace casings during multi-station sausage filling operations. This invention utilizes components such as an elastic clip, a slot, a round rod, and a pressure spring. When meat is being filled into the discharge pipe, the round rod is controlled to be inside the slot. The elastic clip limits the round rod through the slot, ensuring the discharge hole remains horizontal. When the casing connecting structure applies sufficient tension to the adjusting plate via a linkage rope, the round rod pushes the elastic material portion of the slot in the elastic clip, causing it to deform elastically and disengage from the slot. Then, the pressure spring quickly pushes the casing connecting structure, straightening and tightening the linkage rope, causing the discharge hole to quickly separate from the discharge pipe. This invention also utilizes components such as a conical hole, a conical plug, and a flat plate. When the filling position of the discharge pipe needs adjustment, the material block slides on the side of the bottom box. A parallel pusher inside the material block retracts the conical plug inside the block into the corresponding conical hole, allowing meat from the bottom box to be filled into the corresponding material block through the gap between the conical plug and the conical hole. The filling position can be changed as needed. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1-8 The present invention will be described in further detail below.

[0032] This invention discloses a multi-station filling device and method for sausages. Figures 1-8 As shown, it includes a filling pressure tank 1 and a bottom box 2. The lower end of the filling pressure tank 1 is connected to the upper surface of the bottom box 2. Multiple material feeding blocks 3 are installed on the side of the bottom box 2. The upper end of the filling pressure tank 1 is equipped with a feeding mechanism and a mechanism for applying a pushing force to the internal meat material. It can add meat material into the internal meat material and apply a pushing force to the internal meat material. The filling pressure tank 1 presses the meat material into the material feeding blocks 3 through the bottom box 2. The end of the material feeding block 3 near the bottom box 2 is concave and the concave shape of the material feeding block 3 is connected to the inside of the bottom box 2.

[0033] The material guide block 3 is slidably inserted into the side of the bottom box 2. The material guide block 3 can slide on the side of the bottom box 2. A tapered hole 17 is provided on the connecting surface between the bottom box 2 and the material guide block 3. The end of the tapered hole 17 furthest from the bottom box 2 is the larger diameter end. A tapered plug 18 is inserted into the tapered hole 17. The tapered plug 18 is coaxial with the tapered hole 17 and can move along the axis of the tapered hole 17. An elastic telescopic rod 19 is fixed to one end of the tapered plug 18 inside the bottom box 2. The other end of the elastic telescopic rod 19 is fixed to the inner wall of the bottom box 2. The elastic telescopic rod 19 has the function of pushing the tapered plug 18 to seal the tapered hole 17. The conical plug 18 is located outside the bottom box 2. A flat plate 5 is fixedly inserted inside the recessed structure of the material passage block 3. The flat plate 5 is in contact with the outer surface of the bottom box 2. The central axis of the flat plate 5 and the central axis of the conical plug 18 are on the same plane. When the flat plate 5 moves with the material passage block 3 and comes into contact with the conical plug 18, it can push the conical plug 18 to compress the elastic telescopic rod 19, so that a gap is formed between the conical plug 18 and the conical hole 17. The meat in the bottom box 2 enters the material passage block 3 through the gap between the conical plug 18 and the conical hole 17. The position of the filling station of the discharge pipe 4 can be adjusted.

[0034] The material passage block 3 is fixed with a discharge pipe 4 at the end away from the bottom box 2.

[0035] The discharge pipe 4 is provided with fitting arc blocks 11 on both the upper and lower sides of the end away from the feeding block 3. The two fitting arc blocks 11 are detachably connected by bolts. The feeding block 3 is fixedly connected to the adjacent fitting arc block 11. The casing is put on the surface of the discharge pipe 4 so that the casing passes through the two fitting arc blocks 11. The two fitting arc blocks 11 generate resistance to the movement of the casing, preventing the casing from moving too fast from the discharge pipe 4 and the part filled with meat from having wrinkles.

[0036] An adjusting plate 6 is provided between the discharge pipe 4 and the feeding block 3. The feeding block 3 is rotatably sleeved on the outer surface of the adjusting plate 6, and a casing connecting structure 7 is slidably sleeved on the outer surface of the discharge pipe 4.

[0037] The adjusting disc 6 is located on one side of the outer circumference of the feeding block 3, and a vertical shaft 9 is installed. The other end of the vertical shaft 9 is fixed with a linkage rope 8. The other end of the linkage rope 8 is fixed to the casing connection structure 7. The axis of the vertical shaft 9 intersects the axis of the adjusting disc 6 perpendicularly.

[0038] The casing connecting structure 7 includes a reducing collar 71 and multiple clamping plates 72. The outer diameter of the reducing collar 71 at the end away from the material passage block 3 is smaller than the outer diameter of the other end of the reducing collar 71. The clamping plates 72 are located at the smaller diameter end of the reducing collar 71. The reducing collar 71 is slidably sleeved on the outer surface of the discharge pipe 4. A threaded rod 73 is fixed on the side of the clamping plate 72 away from the axis of the reducing collar 71. An internal threaded ring 74 is threaded onto the outer surface of the threaded rod 73. The internal threaded ring 74 is rotatably connected to the reducing collar 71. The end of the casing is sleeved on the smaller diameter end of the reducing collar 71, and then the internal threaded ring 74 is rotated to engage with the threaded rod 73 to push and clamp. Plate 72 presses the casing tightly, fixing the end of the casing to the reducing collar 71. When meat is continued to be filled into the casing after it is tightened, the casing pulls the linkage rope 8 through the reducing collar 71. The small diameter end of the reducing collar 71 is rotated and fitted with a meshing ring 711. A small bevel gear 712 is fixed at the end of the internal threaded ring 74 away from the axis of the reducing collar 71. The small bevel gear 712 meshes with the meshing ring 711. Rotating the meshing ring 711 can drive multiple internal threaded rings 74 to rotate synchronously through the meshing of the small bevel gear 712, so that multiple pressing plates 72 press the casing tightly at the same time. The linkage rope 8 is fixed to the reducing collar 71.

[0039] A material passage hole 10 is provided on the circumferential side of the adjusting plate 6. The material passage hole 10 intersects the axis of the adjusting plate 6 perpendicularly. An elastic clamp 12 is fixed on one side of the material passage block 3. A groove 13 is provided on both sides of the axis of the adjusting plate 6 at the lower end of the elastic clamp 12. The grooves 13 are symmetrically distributed on both sides of the axis of the adjusting plate 6. A round rod 15 is provided inside the groove 13. The round rod 15 is fixed to the end face of the adjusting plate 6. The upper and lower parts of the elastic clamp 12 located in the groove 13 are made of elastic material. When the elastic material of the elastic clamp 12 is subjected to sufficient thrust from the round rod 15, it can deform, and then the round rod 15 can detach from the groove 13. A pressure spring 16 is fixed to one end of the variable diameter collar 71 near the material passage block 3. The other end of the pressure spring 16 is fixed to the discharge pipe 4. The discharge pipe 4 is located on the inner ring side of the pressure spring 16. The two ends of the material passage hole 10 are respectively connected to the inside of the discharge pipe 4 and the recessed structure of the material passage block 3. The pressure spring 16 is in a compressed state. The elastic pressure of the pressure spring 16 is insufficient to push the round rod 15 to deform the elastic material part of the elastic bracket 12. When the round rod 15 is disengaged from the groove 13 under the tension of the casing, the pressure spring 16 can quickly push the variable diameter collar 71 to move, so that the linkage rope 8 is quickly straightened and the material passage hole 10 is quickly misaligned and separated from the discharge pipe 4.

[0040] A rope winding rod 14 is provided on the lower side of the linkage rope 8. The rope winding rod 14 is rotatably connected to the discharge pipe 4. The part of the linkage rope 8 located on the left side of the rope winding rod 14 is horizontal. The rope winding rod 14 limits the movement trajectory of the linkage rope 8.

[0041] This invention also discloses a multi-station filling method for sausages, comprising the following steps:

[0042] S1. Place the sausage casing onto the surface of the discharge pipe 4 and fix the end of the casing through the casing connection structure 7.

[0043] S2. The bottom box 2 fills the meat into the discharge pipe 4 through the material passage hole 10 in the material passage block 3 and the regulating plate 6, and the discharge pipe 4 fills the meat into the casing.

[0044] S3. As meat is gradually filled into the casing, the casing is gradually pulled out from the discharge pipe 4. The casing gradually tightens on the surface of the discharge pipe 4. As meat is continued to be filled into the casing, the casing gradually pulls the casing connecting structure 7 to move.

[0045] S4. The casing connection structure 7 pulls the vertical shaft 9 and the adjusting plate 6 to rotate via the linkage rope 8. The adjusting plate 6 causes the material passage hole 10 to be misaligned with the discharge pipe 4, so that after the casing is used up, the material supply to the discharge pipe 4 stops. During multi-station sausage filling, the staff has enough time to replace the casing with a new one.

[0046] The working principle is as follows: The casing to be filled is placed on the surface of the discharge pipe 4, and then one end of the casing is fixed by the casing connecting structure 7. The two ends of the feeding hole 10 are connected to the recessed structure of the discharge pipe 4 and the feeding block 3. The bottom box 2 fills the discharge pipe 4 with meat through the feeding hole 10 in the feeding block 3 and the adjusting plate 6. The discharge pipe 4 fills the casing with meat. As more meat is gradually filled into the casing, the casing is gradually pulled out from the discharge pipe 4. When the casing is almost used up, the casing gradually tightens on the surface of the discharge pipe 4. When meat is continued to be filled into the casing, the casing gradually pulls the casing connecting structure 7 to move. The casing connecting structure 7 pulls the vertical shaft 9 and the adjusting plate 6 to rotate through the linkage rope 8. The adjusting plate 6 drives the feeding hole 10 to be misaligned with the discharge pipe 4, so that the feeding into the discharge pipe 4 stops after the casing is used up. When filling sausages at multiple stations, the staff has enough time to replace the casings.

[0047] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
