Description

Technical Field

[0001] This invention relates to the field of material crushing technology, and in particular to a meat grinding device for preparing black pork dumplings. Background Technology

[0002] Existing crushing equipment, when processing high-fiber or tough materials, suffers from frictional heating, leading to material adhesion and uneven particle size. Furthermore, the lack of multi-stage crushing and temperature control mechanisms makes it difficult to meet the demands of fine grinding. Meanwhile, traditional meat grinders mostly employ mechanical transmission, relying on the high-speed rotation of a screw propeller or blades to complete the grinding action. However, when dealing with special ingredients like black pork, which has coarse muscle fibers and high fat content, especially in making dumplings where high-quality fillings are crucial, existing equipment often reveals numerous limitations, resulting in its inability to effectively grind black pork from agricultural products. Specifically: Temperature rise affects quality: When a meat grinder is running, the friction between its parts generates heat. This causes the temperature inside the grinding drum to rise. The increased temperature accelerates the melting of fat and denaturation of proteins in the meat, causing the loss of juices and severely affecting the texture and flavor of the black pork filling, making it lose its proper tender and juicy characteristics.

[0003] Limited Functionality and Adaptability: Many meat grinders on the market have relatively limited functions and may not be able to handle the different requirements for the coarseness of various ingredients or fillings. Some machines lack the ability to finely adjust the meat grinding effect, making it difficult to meet users' specific needs for making high-quality black pork dumpling fillings.

[0004] The lack of demand for low-temperature processing: The production of high-quality black pork filling, especially when it is necessary to preserve its original flavor and nutrients, often requires processing in a low-temperature environment to prevent the meat from spoiling due to friction heating. However, existing meat grinding equipment generally lacks active cooling systems or effective temperature control measures.

[0005] Therefore, it is necessary to propose a meat grinding device for preparing black pork dumplings to solve the above problems. Summary of the Invention

[0016] Compared with the prior art, the present invention provides a meat grinding device for preparing black pork dumplings, which has the following beneficial effects: 1. This black pork dumpling mincing equipment not only minces black pork into a suitable filling for dumplings, but also maintains a low-temperature environment during processing to prevent the meat from spoiling due to high temperatures. Through its moving blade shaft, blades, mincing rollers, and threaded grooves, it efficiently processes the relatively coarse muscle fibers and high fat content of black pork. A three-way pipe allows for the injection of coolant to ensure the mincing process is always carried out at a suitable temperature, effectively preventing protein denaturation and fat melting caused by friction-induced heating. This maximizes the preservation of the original flavor, nutrients, and juices of the black pork, resulting in a more tender, juicy, and elastic dumpling filling with clear, non-muddy meat texture. Therefore, it can be specifically designed for processing agricultural products such as black pork.

[0017] 2. This black pork filling dumpling preparation equipment realizes continuous automated processing from feeding to filling output, greatly shortening the time for preparing dumpling filling. It has multi-stage crushing and shearing functions, and its efficiency is significantly improved compared with traditional manual chopping or ordinary household meat grinders. It can quickly meet the meat filling needs of families making dumplings. Moreover, the equipment integrates the functions of initial crushing and low-temperature grinding into the feeding hopper and grinding components.

[0018] 3. This meat grinding equipment for preparing black pork dumplings features adjustable-gap crushing rollers, which can be adjusted according to the size of the black pork and the required degree of crushing. This allows it to pre-crush various sizes of black pork. By activating the servo motor, the first worm wheel is driven through the worm gear, which in turn drives the crushing rollers to rotate and perform the crushing operation. When the spacing of the crushing rollers is adjusted, the first worm wheel rolls on top of the worm gear, thus preventing motion interference.

[0019] 4. The meat grinding equipment for preparing black pork dumplings has a second worm gear that drives the movable frame to move via the connecting shaft. Therefore, the connecting rod can be moved laterally by the C-shaped block. With the help of the guide block, the pre-compression component can be used to squeeze the crushed black pork. This process can squeeze out air and push the pork into the bottom trough for feeding.

[0020] 5. This meat grinding equipment for preparing black pork dumplings features a conical baffle that normally blocks the feeding chute. When the pre-compression component contacts the baffle at an angle, it squeezes the black pork to the bottom, allowing it to be fed through the gap between the conical baffle and the chute. This structure ensures that the black pork is squeezed before further feeding. A spring allows the conical baffle to be reset via a reset block, facilitating the cyclic squeezing and feeding of the crushed black pork.

[0021] 6. This meat grinding equipment for preparing black pork dumplings can convey and compress the crushed black pork through the set threaded grooves and spirally arranged protrusions. The protrusions and threaded grooves can also shear the black pork against each other. When the meat grinding roller rotates, it can generate a strong propulsive force and preliminary crushing ability.

[0022] 7. This meat grinding equipment for preparing black pork dumplings uses blades that first contact the black pork processed by the grinding rollers and perform preliminary cutting. The cut black pork is then thrown towards the curved blades, S-shaped blades, and cross blades. Based on this, a high-speed relative motion can be formed between the rotating blades and the fixed curved, S-shaped, and cross blades. When the black pork is brought between the blades and the curved, S-shaped, and cross blades, it is subjected to a huge shearing force, thus effectively and efficiently cutting it. The blades ensure that all the black pork is swept across the entire effective cutting area of ​​the curved, S-shaped, and cross blades, eliminating any cutting dead corners. Based on this, it can better target the characteristics of black pork, which has coarser muscle fibers and higher fat content. Through the set extrusion template, the black pork can be extruded into minced meat. Attached Figure Description

The bottom of the conical baffle 13 is movably connected to the top of the inner cavity of the meat grinder assembly 3. Fixed rods 15 are symmetrically mounted at the bottom of both ends of the inner cavity of the feeding assembly 1. Springs 16 are wound around the outer wall of the fixed rods 15. Limit blocks are mounted on the top of the springs 16 and are movably connected to the feeding assembly. In the inner cavity of 1, the bottom of spring 16 is installed on the top of reset block 14. Reset block 14 is movably connected in the inner cavity of feeding assembly 1 and sleeved on the outer wall of fixed rod 15. The bottom of pre-pressing assembly 11 is slidably connected to the bottom of the inner cavity of feeding assembly 1. Guide blocks 17 are symmetrically installed at both ends of pre-pressing assembly 11. A guide rod is installed at one end of the bottom of the inner cavity of feeding assembly 1. One end of guide block 17 is sleeved on the outer wall of guide rod. The side of the other end of guide block 17 is connected to connecting rod 18. Linkage assembly 12 is laterally movably connected in the inner cavity of the wall of feeding assembly 1. A C-shaped block 19 is movably connected to one side of the inner cavity of the linkage component 12. The C-shaped block 19 is connected to the connecting rod 18, which is movably connected in the inner cavity of the linkage component 12. A movable frame 20 is rotatably connected to the other side of the inner cavity of the linkage component 12.

It has multi-stage crushing and shearing functions, which significantly improves efficiency compared to traditional manual chopping or ordinary household meat grinders. It can quickly meet the meat filling needs of families making dumplings. Furthermore, the equipment integrates the initial crushing and low-temperature meat grinding functions into the feeding hopper and meat grinding components, and can also effectively serve the countertops of family kitchens. The adjustable spacing of the crushing roller 4 can be adjusted according to the size of the black pork and the required degree of crushing. Based on this, it can be adapted to pre-crushing of black pork of various sizes. By activating the servo motor 5, the first worm wheel 6 can be driven through the worm 7, which in turn drives the crushing roller 4 to rotate and perform crushing work. When the spacing of the crushing roller 4 is adjusted, it can drive the first worm wheel 6 to roll on the top of the worm 7, so there will be no motion interference. The second worm gear 24 can drive the movable frame 20 to move via the connecting shaft 23. Therefore, the connecting rod 18 can be moved laterally by the C-shaped block 19.

[0027] Example 2: like Figures 1-8As shown, a meat grinding device for preparing black pork dumplings includes a meat grinding assembly 3 with a threaded groove 27 on its inner wall. A meat grinding roller 25 is rotatably connected to the inner cavity of the meat grinding assembly 3. A three-way pipe 30 is installed at one end of the meat grinding assembly 3. Protrusions 26 are installed on the outer wall of the meat grinding roller 25. A quick-release ring 31 is provided at the other end of the meat grinding roller 25. A moving blade shaft 37 and a fixed blade shaft 33 are installed in the inner cavity of the quick-release ring 31. The protrusions 26 are spirally arranged on the outer wall of the meat grinding roller 25, and the arrangement of the protrusions 26 is the same as that of the threaded groove 27. Two drive gears 28 are rotatably connected to the inner cavity of the meat grinding assembly 3. One drive gear 28 is connected to the meat grinding roller 25. A drive motor 29 is installed on the outer wall of the meat grinding assembly 3. The drive motor 29 is connected to the other drive gear 28 through a second rotating shaft. The two drive gears 28... The meat grinder roller 25 and the protrusion 26 are hollow structures that mesh with each other. The inner cavity of the meat grinder roller 25 and the protrusion 26 are connected. One end of the three-way pipe 30 passes through one of the drive gears 28 and is connected to the meat grinder roller 25 through a rotating structure. The three-way pipe 30 is connected to the inner cavity of the meat grinder roller 25 and is used to inject and discharge cooling liquid into the meat grinder roller 25. The end of the quick-release ring 31 away from the meat grinder assembly 3 is equipped with a meat extrusion template 32. The outer wall of the moving blade shaft 37 is equipped with a blade 38. One end of the moving blade shaft 37 is inserted into one end of the meat grinder roller 25 through a T-shaped clip. The other end of the moving blade shaft 37 is rotatably connected to the fixed blade shaft 33. The outer wall of the fixed blade shaft 33 near the moving blade shaft 37 is equipped with an arc-shaped blade 34, an S-shaped blade 35 and a cross blade 36 in sequence. The other end of the fixed blade shaft 33 is installed in the center of the side of the meat extrusion template 32. The set threaded groove 27 and spirally arranged protrusions 26 can convey and squeeze the crushed black pork. The protrusions 26, together with the threaded groove 27, can also shear the black pork against each other. When the meat grinder roller 25 rotates, it can generate a strong propulsive force and a preliminary crushing ability. The blade 38 first contacts the black pork processed by the meat grinder 25 and performs initial cutting. The black pork cut by the blade 38 is then thrown towards the curved blade 34, S-shaped blade 35, and cross blade 36. Based on this, the rotating blade 38 and the fixed curved blade 34, S-shaped blade 35, and cross blade 36 can form a high-speed relative motion. When the black pork is brought into the space between the blade 38 and the curved blade 34, S-shaped blade 35, and cross blade 36, it is subjected to a huge shearing force, thus effectively and efficiently cutting it. The blade 38 ensures that all the black pork is swept across the entire effective cutting area of ​​the curved blade 34, S-shaped blade 35, and cross blade 36, eliminating any cutting dead angles. Based on this, it can better target the characteristics of black pork, which has coarser muscle fibers and higher fat content. Through the set extrusion template 32, the black pork can be extruded into minced meat.

[0028] It should be noted that the present invention is a meat grinding device for preparing black pork dumplings. When in use, the black pork is cut into pieces. The distance between the two crushing rollers 4 is adjusted according to the size of the cut black pork pieces. Rotating the handle 10 drives the bidirectional lead screw 9 to rotate, so that the movable block 8 can be threadedly connected to it. At this time, the movable block 8 can drive the crushing rollers 4 to move. After the crushing rollers 4 move, they will drive the first worm gear 6 to roll on the top of the worm 7. After adjustment, the black pork is placed into the inner cavity of the feeding assembly 1 through the feeding hopper 2. The servo motor 5 is started to drive the worm 7 to rotate. After the worm 7 rotates, it will drive the first worm wheel 6 and the second worm wheel 24 to rotate. After the first worm wheel 6 rotates, it can drive the crushing roller 4 to perform preliminary crushing of the black pork. The preliminarily crushed black pork falls to the bottom and will be located at the bottom of the conical baffle plate 13 and the inner cavity of the feeding assembly 1. The rotating second worm gear 24 will drive the gear 21 on one side to rotate through the connecting shaft 23. The gear 21 will mesh with the gear 21 on the other side, thereby driving the C-shaped block 19 to rotate eccentrically. At this time, the connecting rod 18 can be driven to reciprocate left and right. The moving connecting rod 18 can drive the pre-compression component 11 to squeeze the crushed black pork through the guide block 17. The black pork will be squeezed through the conical baffle 13 and the outer wall of the pre-compression component 11. When the pre-compression component 11 contacts the conical baffle 13, it will squeeze it to the bottom through its inclination. Based on this, the squeezed black pork can fall into the inner cavity of the meat grinder 3. Coolant is injected into the inner cavity of the meat grinder roller 25 through the three-way pipe 30. The drive motor 29 is started, and the meat grinder roller 25 is driven through the drive gear 28. The meat grinder roller 25, in conjunction with the threaded groove 27, can convey, squeeze and shear the black pork. The black pork processed by the meat grinder roller 25 can be thrown to the blade 38 for initial crushing, and then further crushed by the arc blade 34, S-shaped blade 35 and cross blade 36. At this time, the black pork can be formed into minced meat through the meat extrusion plate 32.
