Description

Technical Field

[0001] This invention relates to the field of meat processing equipment technology, and in particular to an energy-saving meat cutting device and method based on agricultural and sideline product processing. Background Technology

[0002] In the production of meatballs, meat patties, minced meat products, prepared meat products and other agricultural and sideline food products, raw meat usually needs to be thawed, inedible parts removed, pre-cut, pressed and slit to obtain meat suitable for subsequent marinating, mixing, chopping, shaping or packaging. Existing meat processing equipment usually includes meat grinding equipment, slicing and dicing equipment, rotary cutting equipment and pressing and forming equipment according to the processing purpose. Different equipment use spiral pushing, roller pressing, blade rotary cutting or mold pressing to complete the corresponding process.

[0003] Existing meat grinding equipment mainly relies on a screw conveyor to push the meat towards a perforated plate and cut it by a rotating blade. This is suitable for obtaining granular or minced meat. However, when it is necessary to retain a certain fiber shape and cut loose minced meat into smaller pieces, the screw extrusion and perforated plate shearing can easily change the shape of the meat. Existing slicers and dicers usually require the input meat to have a relatively regular shape and relatively stable size. When the raw material to be processed is loose minced meat formed after pre-cutting, gaps are likely to exist between the minced meat and it may scatter, turn over or shift before entering the blade, causing uneven local load on the blade and affecting the consistency of the cut size.

[0004] To improve the conveying of loose meat, existing production lines often set up hoppers, pressure plates, pressure rollers, or independent pressing equipment in front of the cutting equipment. The degree of aggregation of meat is increased by manual pushing, screw pushing, or unidirectional pressing. Among these methods, the continuity and safety of manual pushing are affected by the operator, and the effect of unidirectional pressing is more concentrated on the localized accumulation of meat. When the pressing equipment and the cutting equipment are arranged separately, intermediate transfer and re-feeding links are also required. The compacted meat may loosen again during the transfer process, making it difficult to maintain a stable connection between the compaction process and the slitting process.

[0005] Therefore, it is necessary to invent an energy-saving meat cutting device and method based on agricultural and sideline product processing to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving meat cutting device and method based on agricultural and sideline product processing, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a meat cutting device based on agricultural and sideline product processing, comprising a frame, wherein a counter-rotating compaction mechanism, a pressing and cutting mechanism, and a discharge mechanism are sequentially arranged on the frame along the conveying direction; the counter-rotating compaction mechanism includes a compaction cylinder, a pressing plate, a rotating pressure component, and a reversing transmission box, wherein the pressing plate and the rotating pressure component are disposed inside the compaction cylinder, the pressing plate is provided with a pressing plate with a concave portion, and the rotating pressure component is provided with an arc-shaped pressure portion opposite to the concave portion, forming a working gap between the two, and a movable baffle is movably arranged at the compaction outlet of the compaction cylinder; the reversing transmission box is provided with The device includes a first bevel gear, a second bevel gear, and a third bevel gear. The first and third bevel gears are respectively connected to the rotating pressure component and the pusher plate. The second bevel gear is rotatably mounted on the reversing transmission box and meshes with the first and third bevel gears, so that the pusher plate rotates in the opposite direction to the rotating pressure component. The pressing and slitting mechanism includes a receiving guide roller, a pressing roller, and a slitting roller equipped with a slitting knife. The pressing roller presses the meat material onto the receiving guide roller for pressing and conveying. The slitting knife presses the meat material against the receiving guide roller for slitting. The discharge mechanism is located below the receiving guide roller.

[0008] Preferably, the compaction cylinder is provided with a feed inlet, which is connected to a feed hopper located above the compaction cylinder; the rotating pressure application component is also provided with a feed guide surface that is connected to the arc-shaped pressure application part, and the feed guide surface extends from the side where the feed inlet is located toward the working gap.

[0009] Preferably, there are multiple push plates, which are distributed at intervals along the circumference of the push plate, and the recessed portion is formed on the side of each push plate facing the arc-shaped pressure part.

[0010] Preferably, the reversing gearbox further includes an input drive shaft, a pressure-applying component drive shaft, and a pressure plate bushing. The first bevel gear, the input drive shaft, and the pressure-applying component drive shaft are fixedly connected, and the pressure-applying component drive shaft is fixedly connected to the rotating pressure-applying component. The third bevel gear is fixedly connected to the pressure plate bushing, and the pressure plate bushing is fixedly connected to the pressure plate. The pressure-applying component drive shaft passes through the pressure plate bushing, and the two are coaxially arranged and can rotate relative to the reversing gearbox.

[0011] Preferably, a discharge guide plate is provided on the outer side of the compaction discharge port, and the discharge guide plate extends toward the pressing area between the pressing roller and the cutting guide roller; the movable baffle is a manually operated opening and closing component that moves between a closed position that closes the compaction discharge port and an open position that avoids the compaction discharge port.

[0012] Preferably, the outer periphery of the pressure roller is provided with a plurality of protrusions, the plurality of protrusions being distributed at intervals along the outer periphery of the pressure roller, and the free ends of the protrusions facing the radially outward side of the pressure roller.

[0013] Preferably, a plurality of slitting blades are provided, and the plurality of slitting blades are distributed at intervals along the axial direction of the slitting roller, with the cutting edge of the slitting blade protruding from the outer periphery of the slitting roller and facing the receiving guide roller.

[0014] Preferably, the discharge mechanism includes a discharge trough disposed below the cutting guide roller and a peeling and draining plate disposed between the cutting guide roller and the discharge trough. The peeling and draining plate has a meat peeling part near the outer periphery of the cutting guide roller and a draining trough for collecting the juice generated during the meat extrusion and cutting process. The bottom end of the draining trough is connected to the discharge trough.

[0015] Preferably, the frame is equipped with a drive motor, which is connected to the input drive shaft, the pressure roller and the slitting roller respectively to form three power branches for driving the counter-rotating compaction mechanism, the pressure roller and the slitting roller.

[0016] A method for cutting meat based on agricultural and sideline product processing includes the following steps: Step 1: Close the movable baffle at the compaction outlet of the compaction cylinder, and feed the minced meat into the working gap between the push plate and the arc-shaped pressure part inside the compaction cylinder; Step 2: Drive the first bevel gear and the rotating pressure component to rotate through the input transmission shaft. The first bevel gear drives the push plate to rotate in the opposite direction through the rotatably mounted second and third bevel gears in sequence. This causes the concave part of the push plate and the arc-shaped pressure part to compact the minced meat while maintaining the working gap. Step 3: Manually open the movable baffle to allow the compacted meat to enter the pressing and cutting mechanism through the compaction outlet; Step 4: Use the pressure roller to press the meat onto the cutting guide roller and convey it to the slitting position. Then use the slitting blade on the slitting roller to press the meat against the cutting guide roller for slitting. Step 5: The cut meat is guided by the cutting guide roller to the discharge mechanism and discharged.

[0017] The technical effects and advantages of this invention are as follows: 1. This invention sets up a pressing plate with a recessed pressing plate and a rotating pressing component with an arc-shaped pressing part inside the compaction cylinder. It uses a first bevel gear, a rotatably mounted second bevel gear and a third bevel gear to form a reversing transmission, so that the pressing plate and the rotating pressing component rotate in opposite directions during operation. After the feeding guide surface guides the loose minced meat into the working gap between the recessed part and the arc-shaped pressing part, multiple pressing plates participate in pushing the material in sequence, and the arc-shaped pressing part applies a reverse constraint to the meat entering the working gap. The movable baffle restricts the meat from leaving the compaction cylinder directly when it is closed, so that the minced meat is gathered and compacted before entering the cutting area. By manually opening the movable baffle to establish a clear discharge time, it is beneficial to reduce the possibility of the loose meat turning over and local accumulation when it directly enters the roller cutting area. 2. This invention arranges the pressure roller and the slitting roller around the receiving guide roller, so that the pressure roller first presses the meat onto the receiving guide roller and uses the protrusions to form a gripping conveyor. Then, the slitting blade presses the meat onto the same receiving guide roller for slitting. The receiving guide roller forms a pressure reaction support in the previous stage and a slitting object in the next stage, so that the meat can maintain a continuous support reference when moving from the pressure position to the slitting position. After cutting, the meat is guided away from the roller surface by the meat peeling part near the outer periphery of the receiving guide roller. The juice generated by squeezing and slitting enters the drainage trough and is guided from its bottom end to the discharge trough, thereby closing the meat pressure, cutting, peeling and discharge path, and reducing the impact of meat and juice stagnation near the roller surface on subsequent feeding. 3. This invention, by setting a drive motor on the frame and having the drive motor transmit power to the input transmission shaft, the pressure roller, and the slitting roller respectively, forms three transmission branches under the same power source for counter-rotating compaction, roller conveying, and roller cutting. Without changing the main technology chain of counter-rotating compaction and cutting, the number of independent drive motors and their mounting components is reduced. At the same time, the intermittent compaction and discharge is connected with the downstream pressure conveying and cutting by using a movable baffle. Thus, the energy-saving effect is maintained as an auxiliary effect of the overall machine power configuration, while taking into account the centralized structure of the equipment and the continuity of the processing flow.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 10 As shown, the energy-saving meat cutting equipment and method based on agricultural and sideline product processing provided by the present invention essentially utilizes a counter-rotating compaction structure to first gather and intermittently compact loose minced meat, then uses the receiving and guiding roller 31 as the pressure feeding reaction support and the cutting object to complete the pressure feeding and cutting, and completes the meat stripping, juice diversion and discharge through the discharge mechanism 4 set below the receiving and guiding roller 31.

[0031] In terms of specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. For ease of explanation, this embodiment takes the direction in which the meat material enters the compaction cylinder 21 from the feed hopper 241 and moves to the discharge trough 41 through the pressing and cutting mechanism 3 as the conveying direction. The side closer to the feed hopper 241 is the feeding side, and the side closer to the outlet of the discharge trough 41 is the discharge side.

[0032] The meat cutting equipment in this embodiment includes a frame 1, a drive motor 11, a counter-rotating compaction mechanism 2, a pressing and slitting mechanism 3, and a discharge mechanism 4. The frame 1 consists of an upper support area, a middle working area, and a lower discharge area. The drive motor 11 and the feed hopper 241 are located at the upper part of the frame 1. The counter-rotating compaction mechanism 2 and the pressing and slitting mechanism 3 are located at the middle part of the frame 1. The discharge mechanism 4 is located below the pressing and slitting mechanism 3, so that the meat can be fed, compacted, pressed, slitted, and discharged sequentially from top to bottom under the pushing action of gravity and each rotating component.

[0033] The drive motor 11 is fixedly installed in the upper support area of ​​the frame 1. The drive motor 11 is connected to the input drive shaft 251, the pressure roller 32 and the slitting roller 33 respectively. The transmission structure shown in the figure consists of three power branches consisting of pulleys, transmission belts and gears. The first power branch transmits power to the input drive shaft 251 and drives the counter-rotating compaction mechanism 2 to work. The second power branch drives the pressure roller 32 to rotate. The third power branch drives the slitting roller 33 to rotate. Thus, compaction, pressure feeding and slitting actions are formed under the power output of one drive motor 11. This shared drive structure serves as an auxiliary energy-saving configuration for the whole machine without changing the main structural coordination relationship between the various working mechanisms.

[0034] The counter-rotating compaction mechanism 2 includes a compaction cylinder 21, a pressing plate 22, a rotating pressure application component 23, a feed inlet 24, a feed hopper 241, and a reversing transmission box 25. The compaction cylinder 21 is fixedly supported in the middle of the frame 1 and forms a cylindrical working chamber for accommodating meat. The feed inlet 24 is formed on the feed side of the compaction cylinder 21 and communicates with the feed hopper 241 above, so that the pre-cut minced meat can be collected by the feed hopper 241 and fall into the compaction cylinder 21 through the feed inlet 24.

[0035] The rotating pressure member 23 is disposed inside the compaction cylinder 21 on the side near the feed inlet 24. The rotating pressure member 23 has a feed guide surface 231 and an arc-shaped pressure part 232 connected to the feed guide surface 231. The feed guide surface 231 extends from the side where the feed inlet 24 is located toward the pressure plate 22 and receives the minced meat entering the compaction cylinder 21 when the rotating pressure member 23 rotates. The arc-shaped pressure part 232 faces the pressure plate 22 and forms an arc-shaped working surface that applies constraint and compression to the meat.

[0036] The pressing plate 22 and the rotating pressure component 23 are coaxially arranged inside the compaction cylinder 21. Multiple pressing plates 221 are arranged circumferentially on the pressing plate 22. Each pressing plate 221 forms a concave portion on the side facing the arc-shaped pressure part 232. The contour of the concave portion is relatively adapted to the arc-shaped pressure part 232 and a working gap is maintained between them. After the feed guide surface 231 guides the meat to the working gap, the relative movement of the pressing plate 221 and the arc-shaped pressure part 232 pushes and compacts the meat. The working gap provides space for the meat to pass through and restricts the meat from spreading out disorderly in the compaction cylinder 21.

[0037] The reversing gearbox 25 is installed on the drive side of the compaction cylinder 21. The reversing gearbox 25 is equipped with a first bevel gear 252, a second bevel gear 253 and a third bevel gear 254. The reversing gearbox 25 also provides rotational support for the input drive shaft 251, the pressure application drive shaft 233 and the pusher plate bushing 222, so that each transmission component meshes at a determined axial position and transmits power to the pusher plate 22 and the rotating pressure application component 23 in the compaction cylinder 21.

[0038] The first bevel gear 252, the input drive shaft 251, and the pressure application drive shaft 233 are fixedly connected. The pressure application drive shaft 233 is fixedly connected to the rotating pressure application component 23. Therefore, when the input drive shaft 251 rotates, it can drive the first bevel gear 252, the pressure application drive shaft 233, and the rotating pressure application component 23 to rotate synchronously. The third bevel gear 254 is fixedly connected to the pressure plate bushing 222, and the pressure plate bushing 222 is fixedly connected to the pressure plate 22, so that the third bevel gear 254 can drive the pressure plate 22 to rotate via the pressure plate bushing 222.

[0039] The second bevel gear 253 is rotatably mounted on the reversing gearbox 25 and meshes with the first bevel gear 252 and the third bevel gear 254 at the same time. The rotation input by the first bevel gear 252 is transmitted to the third bevel gear 254 after being reversed by the second bevel gear 253, so that the push plate 22 connected to the third bevel gear 254 and the rotating pressure member 23 connected to the first bevel gear 252 form a reverse rotation relationship. The pressure member drive shaft 233 passes through the push plate bushing 222 and the two are arranged coaxially. The two maintain an assembly relationship that allows relative rotation, so that the coaxially arranged push plate 22 and rotating pressure member 23 can receive two power outputs in opposite directions respectively. In this embodiment, the three bevel gears can be combined with different gear ratios so that the rotational speed of the rotating pressure component 23 exceeds that of the pressure plate 22, thereby achieving multiple compactions of the meat product within one compaction cycle.

[0040] When the pressing plate 22 and the rotating pressure component 23 rotate in opposite directions, multiple pressing plates 221 pass through the relative positions of the arc-shaped pressure part 232 in sequence. The minced meat entering the working gap is pushed by the pressing plate 221 moving circumferentially, and constrained by the arc surface of the arc-shaped pressure part 232. This causes the originally loosely distributed minced meat to gather into the working gap and be squeezed. After passing the arc-shaped pressure part 232, the pressing plate 221 continues to rotate with the pressing plate 22, so that the subsequent pressing plate 221 can repeatedly participate in the feeding and compaction process.

[0041] The compaction cylinder 21 has a compaction outlet 211 on its circumferential side. A movable baffle 213 is movably installed at the compaction outlet 211. The movable baffle 213 is manually operated and can move between a closed position and an open position. When the movable baffle 213 is in the closed position, it covers or blocks the compaction outlet 211 to prevent the meat from leaving the compaction cylinder 21 in advance. When the movable baffle 213 is in the open position, it avoids the compaction outlet 211, so that the compacted meat can be discharged from the compaction outlet 211 under the pushing of the pressing plate 221 and its own gravity.

[0042] A discharge guide plate 212 is provided on the outside of the compaction discharge port 211. The discharge guide plate 212 extends obliquely from the compaction discharge port 211 toward the pressing area between the pressing roller 32 and the cutting guide roller 31. The discharge guide plate 212 supports and reverses the direction of the meat released from the compaction cylinder 21, so that the meat remains concentrated when it enters the pressing area from the compaction area and reduces the possibility of it scattering outside the pressing and cutting mechanism 3.

[0043] The pressing and slitting mechanism 3 includes a receiving guide roller 31, a pressing roller 32, and a slitting roller 33. The receiving guide roller 31, the pressing roller 32, and the slitting roller 33 are all rotatably mounted in the middle working area of ​​the frame 1. The pressing roller 32 is located downstream of the discharge guide plate 212 and is arranged opposite to the receiving guide roller 31. The slitting roller 33 is arranged downstream of the pressing roller 32 along the meat movement direction of the receiving guide roller 31, so that the meat first passes through the pressing area between the pressing roller 32 and the receiving guide roller 31, and then enters the slitting area between the slitting roller 33 and the receiving guide roller 31.

[0044] Multiple protrusions 321 are provided on the outer periphery of the pressure roller 32. The protrusions 321 are distributed at intervals along the outer periphery of the pressure roller 32 and their free ends face the radial outer side of the pressure roller 32. When the pressure roller 32 rotates, it presses the meat material against the cutting guide roller 31 and the cutting guide roller 31 provides the reaction force. After the protrusions 321 penetrate or bite the surface of the meat material, they rotate with the pressure roller 32, so that the compacted meat material overcomes the influence of the wet and slippery surface and moves along the outer periphery of the cutting guide roller 31 towards the cutting area.

[0045] Multiple slitting blades 331 are arranged on the outer periphery of the slitting roller 33. The multiple slitting blades 331 are distributed at intervals along the axial direction of the slitting roller 33 and the blades protrude from the outer periphery of the slitting roller 33. The slitting blades 331 face the receiving guide roller 31 and form a slitting position to receive meat material between them. When the slitting roller 33 rotates, it drives the slitting blades 331 to act on the meat material fed by the pressure roller 32 in sequence. The slitting blades 331 press the meat material against the receiving guide roller 31 and use the reaction force provided by the receiving guide roller 31 to complete the slitting.

[0046] The cutting guide roller 31 is located between the pressure conveying roller 32, the slitting roller 33 and the discharge mechanism 4. In the pressure conveying area, the cutting guide roller 31 bears the force transmitted by the pressure conveying roller 32 through the meat and forms a pressure conveying reaction support. In the slitting area, it bears the cutting force transmitted by the slitting blade 331 through the meat and forms a cutting object. At the same time, it uses its own roller surface to support the cut meat and change the direction of movement of the meat, so that the meat shares a continuous support reference in the pressure conveying and slitting stages without having to be transferred between two independent support structures.

[0047] The discharge mechanism 4 includes a discharge trough 41 and a stripping and draining plate 42. The discharge trough 41 is inclinedly arranged below the cutting guide roller 31 and extends outward from the frame 1. The stripping and draining plate 42 is arranged between the cutting guide roller 31 and the discharge trough 41. The stripping and draining plate 42 receives the cut meat material discharged by the cutting guide roller 31 and the juice generated by the meat material during the compaction, pressing and cutting process.

[0048] The peeling and draining plate 42 forms a meat peeling part 422 at one end near the cutting guide roller 31. The meat peeling part 422 is arranged near the outer periphery of the cutting guide roller 31. When the cut meat moves to the discharge area with the cutting guide roller 31, the meat peeling part 422 peels and guides the meat attached to the roller surface, so that the meat leaves the cutting guide roller 31 and enters the discharge trough 41 along the peeling and draining plate 42.

[0049] A drainage trough 421 is also formed on the stripping drainage plate 42. The drainage trough 421 collects and guides the juice that separates from the meat and falls onto the stripping drainage plate 42. The bottom end of the drainage trough 421 is connected to the discharge trough 41, so that the juice enters the discharge trough 41 from the drainage trough 421 and is discharged out of the equipment with the discharge trough 41. The meat stripping section 422 and the drainage trough 421 first form a path separation between the meat and the juice at the stripping position. Both are eventually discharged by the discharge trough 41 without the need to set up independent final outlets.

[0050] In this embodiment, the surfaces of the compaction cylinder 21, the pressing plate 22, the rotating pressure component 23, the discharge guide plate 212, the cutting guide roller 31, the pressing roller 32, the slitting roller 33, the slitting knife 331, the discharge trough 41, and the peeling and draining plate 42 that come into contact with the meat are processed in accordance with the hygiene requirements of food processing equipment. In actual manufacturing, each working surface is kept free of burrs that would hinder the movement of the meat and is easy to clean after the machine is stopped. This conventional manufacturing requirement does not change the connection and working relationship between the aforementioned structures.

[0051] The complete workflow of this embodiment is described below.

[0052] Step 1: Close the movable baffle 213 at the compaction outlet 211 of the compaction cylinder 21, keeping the movable baffle 213 in the closed position to prevent meat from being discharged. Feed the pre-cut minced meat into the feed hopper 241. Under the action of gravity, the minced meat enters the compaction cylinder 21 through the feed inlet 24. The feed guide surface 231 on the rotating pressure member 23 receives the minced meat and guides it to the working gap between the concave part of the push plate 221 and the arc-shaped pressure part 232, thereby completing the centralized feeding before compaction.

[0053] Step 2: Start the drive motor 11. The first power branch of the drive motor 11 drives the input transmission shaft 251 to rotate. The input transmission shaft 251 drives the first bevel gear 252, the pressure component transmission shaft 233 and the rotating pressure component 23, which are fixedly connected to it, to rotate synchronously. The first bevel gear 252 drives the third bevel gear 254 to output in the opposite direction via the second bevel gear 253, which is rotatably mounted on the reversing transmission box 25. The third bevel gear 254 drives the pressure plate 22 to rotate in the opposite direction relative to the rotating pressure component 23 via the pressure plate bushing 222. Multiple pressure plates 221 push the minced meat into the working gap in sequence. The arc-shaped pressure part 232 applies relative constraint to the meat. The movable baffle 213 remains closed during this stage, so that the minced meat is gathered and compacted in the compaction cylinder 21.

[0054] Step 3: The operator manually opens the movable baffle 213 according to the processing needs, so that the movable baffle 213 moves from the closed position to the open position to avoid the compaction outlet 211. The compacted meat leaves the compaction cylinder 21 through the compaction outlet 211 under the pushing action of the continued rotation of the push plate 221 and its own gravity. The discharge guide plate 212 receives the meat and guides it to the pressing area between the pressing roller 32 and the cutting guide roller 31, thereby connecting the intermittent compaction and discharge process with the downstream pressing and cutting process.

[0055] Step four: The second power branch of the drive motor 11 drives the pressure roller 32 to rotate. The pressure roller 32 presses the meat onto the cutting guide roller 31 and holds the meat with the protrusions 321, causing the meat to move along the outer periphery of the cutting guide roller 31 towards the slitting area. At the same time, the third power branch of the drive motor 11 drives the slitting roller 33 to rotate. Multiple slitting blades 331 on the slitting roller 33 act sequentially on the pressed meat and press the meat against the cutting guide roller 31. The cutting guide roller 31 provides a reaction force to the slitting action, so that the meat can be continuously slitted while maintaining the support reference.

[0056] Step 5: The cut meat moves towards the discharge mechanism 4 along the cutting guide roller 31. When the meat reaches the discharge area of ​​the cutting guide roller 31, the meat peeling part 422 peels the meat off the roller surface. The peeled meat falls into the discharge trough 41 along the peeling and draining plate 42 and is discharged from the equipment through the discharge trough 41. The juice that is separated during the compaction, pressing and cutting process falls into the draining plate 42 and enters the discharge trough 421. The juice flows along the discharge trough 421 to its bottom and enters the discharge trough 41 through the connection position with the discharge trough 41, thereby completing the discharge of the cut meat, juice and residue.

[0057] In summary, this invention utilizes the counter-rotation of the pressing plate 22 and the rotating pressing component 23, as well as the working gap between the recessed portion of the pressing plate 221 and the arc-shaped pressing part 232, to gather and compact loose minced meat. The compacted meat is then released by the movable baffle 213, and the pressing roller 32 and the cutting blade 331 work together with the cutting guide roller 31 as a reaction force support to complete the pressing and cutting. Finally, the discharge path is closed through the meat stripping part 422, the liquid drain trough 421 and the discharge trough 41, thus forming a complete processing chain of minced meat compaction, cutting and discharge. The three power branches formed by the drive motor 11 are only used as auxiliary energy-saving configurations for the whole machine.

[0058] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
