Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a meat paste filling and processing component. Background Technology

[0002] As an important category of traditional meat products, sausage production mainly includes raw material processing, mincing and emulsification, meat paste filling, tying and segmenting, cooking and sterilization, and packaging. Among these, meat paste filling is one of the key processes that determines product quality and production efficiency. Sausage meat paste is usually made from livestock and poultry meat through mincing, chopping, or emulsification. It has high viscosity, high oil content, and certain elastic rheological properties, which places high demands on the conveying stability, metering accuracy, and sealing performance of filling equipment.

[0003] Patent CN222485998U discloses an automated filling device. This device includes a mixing drum, a discharge pipe, a screw conveyor mechanism, and a seasoning quantitative addition system. The device uses a weight sensor to detect the mass of meat in the mixing drum. A controller adjusts the frequency of the electric telescopic rod based on the meat quantity, driving the quantitative block to reciprocate and achieve automatic and precise seasoning dispensing. After the seasoning is added, the mixing motor drives the mixing shaft and screw blades to rotate, completing the meat mixing. The screw blades then propel the meat paste continuously from the discharge pipe, effectively preventing the contents from overflowing. The material blockage at the discharge port improves the integration of mixing and conveying. Although this technology has made some progress in automatic seasoning and anti-blocking conveying, there are still some shortcomings in practical application. The discharge pipe of this device is a normally open structure. When filling is paused, casings are changed, or filling connectors are not installed, the discharge port cannot be automatically closed. Due to the high viscosity and residual pressure of sausage meat paste, slow overflow or dripping of materials is very likely to occur during shutdown. This not only wastes raw materials, but also contaminates the filling head, equipment table and unused casings, increases cleaning difficulty, and affects the hygiene of the production environment.

[0004] Therefore, there is an urgent need to provide a meat paste filling and processing component that can automatically close the discharge port. Utility Model Content

[0005] In order to overcome the shortcomings of existing patented meat paste filling equipment, such as the lack of automatic sealing function at the outlet during filling gaps or container changes, which easily leads to high-viscosity meat paste dripping, environmental pollution, inaccurate measurement, and poor hygiene performance, this utility model provides a meat paste filling and processing component that can realize automatic sealing of the outlet.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a meat paste filling and processing assembly, comprising a support frame, a storage hopper mounted on the support frame, a filling pipe connected to the bottom of the storage hopper, a servo motor mounted on the top of the support frame, an output shaft of the servo motor connected to a connecting rod via a coupling, a threaded conveying rod connected to the bottom end of the connecting rod, symmetrically distributed sealing baffles at the outlet end of the filling pipe, a guiding slope on the side of each sealing baffle facing the center of the filling pipe, symmetrically distributed guide rods fixed to the bottom of the support frame, the guide rods slidably connected to the sealing baffles, and a spring sleeved on the guide rod, one end of the spring connected to the support frame and the other end connected to the sealing baffle.

[0007] As a further preferred embodiment, an observation plate is embedded in the front side of the storage hopper.

[0008] As a further preferred embodiment, a connecting plate is fixedly mounted on the upper end of the connecting rod by screws, and a cleaning scraper is fixedly connected to the connecting plate. The shape of the cleaning scraper matches the inverted conical inner wall of the storage hopper.

[0009] As a further preferred embodiment, the top of the storage hopper is provided with a protective cover, a rotating shaft is hinged to the front side of the protective cover, a protective cap is provided on the rotating shaft, and a handle is provided on the front side of the protective cap.

[0010] As a further preferred embodiment, a damping ring is fitted around the outside of the rotating shaft.

[0011] As a further preferred embodiment, the servo motor is provided with a protective shell.

[0012] To address the aforementioned issues, this utility model employs the following technical solution: 1. By installing a symmetrical sealing baffle with spring reset at the outlet end of the filling pipe, and in conjunction with a guiding inclined structure, a mechanical linkage function is achieved that automatically opens when the container is in place and automatically closes when the container is removed. When there is no filling joint, the sealing baffle closes tightly under the action of the spring force, reliably sealing the outlet and completely avoiding the leakage caused by gravity or residual pressure due to high-viscosity meat paste, thus reducing raw material waste and improving equipment cleanliness.

[0013] 2. By installing a connecting plate with a cleaning scraper on the connecting rod or threaded conveyor rod, the scraper rotates synchronously with the main shaft. Its shape matches the inverted conical inner wall of the storage hopper, and its outer edge is in close contact with the inner wall surface. During equipment operation, the cleaning scraper continuously scrapes the high-viscosity meat paste adhering to the inner wall of the storage hopper downwards and guides it into the feeding pipe area, avoiding the accumulation, clumping or deterioration caused by long-term material retention. This significantly improves the continuity and stability of material feeding, reduces the frequency of manual cleaning, and improves production efficiency.

[0014] 3. The top of the hopper is equipped with a flip-open protective cover. During normal operation or when not feeding, the bottom of the protective cover fits tightly with the top of the storage hopper to form an effective seal. This can prevent external dust, flying insects, foreign objects, etc. from entering the storage cavity, prevent raw material contamination, and ensure the hygiene level of the meat paste processing environment.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 1-3A meat paste filling and processing assembly includes a support frame 1, on which a storage hopper 2 with an inverted conical structure is mounted. An observation plate 10 is embedded in the front of the storage hopper 2, allowing operators to observe the material feeding status, residue levels, and the operation of the threaded conveyor rod 6 in real time, promptly identifying problems such as blockages, bridging, or insufficient material supply. A filling pipe 3 is connected to the bottom of the storage hopper 2. A servo motor 4 is mounted on the top of the support frame 1, and the servo motor 4 is covered by a protective shell 19, forming a physical barrier that provides dustproof, waterproof, oilproof, and mechanical damage protection. The output shaft of the servo motor 4 is connected to a vertically downward-arranged connecting rod 5 via a coupling. The bottom end of the connecting rod 5 is connected to the threaded conveyor rod 6. The material is inserted into the filling tube 3 to push the material downward from the storage hopper 2. The outlet end of the filling tube 3 is provided with symmetrically distributed sealing baffles 8. The two sealing baffles 8 are arranged opposite each other and jointly seal the outlet of the filling tube 3. Each sealing baffle 8 has a guide slope on the side facing the center of the filling tube 3. The slope is arranged upward and is used to contact the filling connector on the casing and guide it to push open the sealing baffle 8. The bottom of the support frame 1 is fixed with symmetrically distributed guide rods 7. The guide rods 7 are slidably connected to the sealing baffles 8. A spring 9 is sleeved on the guide rod 7. One end of the spring 9 is connected to the support frame 1 and the other end is connected to the sealing baffle 8. Under normal conditions, it provides an inward elastic force to close the two sealing baffles 8 and fit them tightly to block the outlet.

[0023] When using this device for filling operations, the casings to be filled are placed on the metal or plastic filling connector, and the connector is aligned directly below the filling tube 3. The operator or automated robot moves the filling connector vertically upward, until its edge contacts the guide slopes on the two sealing baffles 8. Under the upward thrust, the slopes convert the vertical force into a horizontal component, forcing the two sealing baffles 8 to overcome the elasticity of the spring 9 and slide outward along the guide rod 7, thereby opening the outlet of the filling tube 3. At this point, the filling connector is completely locked onto the filling tube 3, ready to receive material. The servo motor 4 is then started, and power is supplied. The feed is transmitted to the connecting rod 5 via the coupling, which drives the threaded conveying rod 6 to rotate inside the filling pipe 3. This pushes the meat paste in the storage hopper 2 downwards in a quantitative and continuous manner and fills it into the casings through the open outlet. After filling is completed, the servo motor 4 is turned off to stop the feeding. Then, the filled casings and their filling connectors are removed downwards. The sealing baffles 8 are no longer subjected to the squeezing force from the filling connectors. Under the restoring force provided by the spring 9, the two sealing baffles 8 automatically slide inwards to reset, immediately sealing the outlet and effectively preventing residual material from dripping. This keeps the equipment clean, and the device returns to its initial standby state, ready for the next filling cycle.

[0024] Example 2: Based on Example 1, please refer to... Figure 4The upper end of the connecting rod 5 is fixedly provided with a connecting plate 11 by screws 13. A cleaning scraper 12 is fixedly connected to the connecting plate 11. The shape of the cleaning scraper 12 matches the inverted conical inner wall of the storage hopper 2.

[0025] During equipment operation, the servo motor 4 drives the connecting rod 5 and the threaded conveying rod 6 to rotate synchronously. The connecting plate 11, which is installed at the lower part of the connecting rod 5 or the upper end of the threaded conveying rod 6, rotates accordingly, causing the cleaning scraper 12 to rotate around the central axis. Since the outline of the cleaning scraper 12 matches the inverted conical inner wall of the storage hopper 2, its outer edge is always in close contact with the inner wall surface. During the rotation, the high-viscosity meat paste adhering to the wall of the storage hopper 2 is scraped downward and pushed into the filling pipe 3 area below to participate in subsequent conveying and filling, preventing material residue, clumping or deterioration, and improving the smoothness of material discharge and the hygiene performance of the equipment.

[0026] Please see Figure 5 The storage hopper 2 is provided with a protective cover 14 on the top. A rotating shaft 15 is hinged to the front side of the protective cover 14. A protective cover 16 is provided on the rotating shaft 15. A handle 17 is provided on the front side of the protective cover 16. A damping ring 18 is sleeved on the outside of the rotating shaft 15 to provide rotational damping torque, so that the protective cover 16 can slowly and smoothly flip upward during the opening process, avoiding the cover from swinging violently or hitting the equipment due to gravity or too fast operation.

[0027] When the equipment is running or not being fed, the protective cover 16 is in a closed state, with its bottom edge tightly fitted to the top of the storage hopper 2. This effectively prevents external dust, flying insects, foreign objects, etc., from falling into the storage hopper 2, ensuring the hygienic safety of meat paste processing. It also prevents operators from accidentally putting their hands or tools into the storage hopper 2 while the equipment is running, causing mechanical injury and significantly improving the inherent safety of the equipment. When it is necessary to add meat paste or other materials to the storage hopper 2, the operator holds the handle 17 on the front side of the protective cover 16 and applies external force to make the protective cover 16 rotate upward around the pivot 15 to open it, exposing the feeding port of the storage hopper 2. Manual feeding or connection to the automatic feeding system can then be carried out. After feeding is completed, the protective cover 16 is reset and closed to ensure that the subsequent filling process is carried out in a closed, clean, and safe environment.

[0028] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
