Description

Technical Field

[0001] This invention relates to the field of meat cutting technology, specifically to an energy-saving intelligent production line for equal-weight cutting of fresh meat. Background Technology

[0002] As is generally known, fresh meat usually refers to unprocessed, fresh meat, including pork, beef, lamb, and chicken. These meats are popular with consumers due to their high freshness, good taste, and rich nutrition. During packaging, fresh meat needs to be cut into equal-weight pieces. This cutting requires a production line. A smart production line for equal-weight cutting of fresh meat uses a high-resolution camera mounted on top of a conveyor belt. This camera scans and identifies the meat to be cut, acquiring data such as the size and shape of the pieces in real time. This data is then transmitted to a control algorithm for processing. Based on factors such as meat quality, shape, and weight, the machine is intelligently controlled to perform precise cutting. By monitoring and adjusting the cutting quality, the weight of the cut meat can be kept within a fixed range, thus achieving equal-weight cutting of fresh meat.

[0003] For example, the patent titled "A Meat Strip Slitting Machine for Fresh Meat Processing," published on June 24, 2025, with announcement number CN119522958B, discloses a meat strip slitting machine for fresh meat processing. This patent relates to the field of fresh meat processing technology and includes a rotating shaft fixedly connected to a transmission component. The rotating shaft is driven by the transmission component to the output end of a motor. A cutting component is fixedly connected to the outer side of the rotating shaft. A rotating rod is rotatably connected to a protective component near the rotating shaft, and a rotating cylinder is fixedly connected to the outer side of the rotating rod. The cutting component includes a turntable fixedly connected to the rotating shaft. An inclined groove is formed on the outer edge of the turntable, and a blade is fixedly connected inside the inclined groove. A fixing rod is fixedly connected to the outer side of the turntable near the blade, and the turntable is fixedly connected to the blade via the fixing rod. This meat strip slitting machine for fresh meat processing, by using an inclined blade, allows for precise cutting of the fresh meat.

[0004] Due to the angle at which the blade contacts the fresh meat, it is easier to guide the meat to be cut along the direction of the blade, resulting in a smoother cut and improved product quality.

[0005] The shortcoming of existing technology is that the intelligent production line for heavy cutting of fresh meat can only cut fresh meat. However, some of the meat to be cut contains bones, which requires bone cutting. When cutting bones, existing technology requires an additional production line. Summary of the Invention

[0006] The purpose of this invention is to provide an energy-saving intelligent production line for equal-weight cutting of fresh meat, thereby solving the technical problems in related technologies.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an energy-saving intelligent production line for equal-weight cutting of fresh meat, comprising a frame, on which a first conveyor belt and a second conveyor belt are arranged, and further comprising a blade changing unit, wherein the blade changing unit comprises a chopping frame and a meat cutting frame, the chopping frame being arranged on one side of the second conveyor belt on the frame, the chopping frame being equipped with a reciprocating bone-chopping knife, and the meat cutting frame being arranged on the frame at the gap between the first and second conveyor belts, the meat cutting frame being equipped with a reciprocating oscillating meat-cutting knife, wherein when the bone-chopping knife is in the cutting position, the bone-chopping knife performs cutting operations on the bone; and when the meat cutting knife is in the cutting position, the meat cutting knife performs cutting operations on the fresh meat.

[0008] As described above, the meat cutting rack has a blade groove that is compatible with the cutting head blade, and a first driving member is provided on the outer wall of the meat cutting rack. The output end of the first driving member passes through the blade groove and is connected to a meat cutting shaft, and a meat cutting blade is provided on the meat cutting shaft.

[0009] As described above, the meat cutting rack and the chopping frame are both rotatably mounted on the frame at the connection position of the first conveyor belt and the second conveyor belt via a driven shaft. A second driving component is installed on the top of the chopping frame, and the output end of the second driving component is connected to a bone-chopping knife.

[0010] As described above, the chopping frame is provided with a first sliding groove, the cleaver is slidably installed in the first sliding groove, the meat cutting rack is provided with a second sliding groove, and the second sliding groove and the cleaver are slidably adapted to each other.

[0011] As described above, the chopping frame is provided with a docking groove, and the docking groove and the meat cutting frame are mutually abutting and supporting each other.

[0012] As described above, a first support rod is provided on one side of the first conveyor belt on the frame, and the first support rod and the meat cutting rack are fitted together and abut against each other.

[0013] As described above, a second support rod is provided on one side of the second conveyor belt on the frame, and the second support rod and the chopping frame are fitted together and abut against each other.

[0014] As described above, a third driving component is mounted on each of the two side walls of the frame at the connection position of the first conveyor belt and the second conveyor belt via a motor mount. Each of the output ends of the third driving component is connected to a driving gear, and a driven gear is mounted on each of the two driven shafts. The two driving gears are respectively meshed with their corresponding driven gears.

[0015] As described above, a plurality of abutting rollers are rotatably arranged on the frame, and each abutting roller is respectively abutted against its corresponding first conveyor belt and second conveyor belt, so that each abutting roller tensions the first conveyor belt and the second conveyor belt.

[0016] As mentioned above, a guide plate is provided on the top of the frame on one side of the first conveyor belt.

[0017] The beneficial effects of this invention are as follows: When fresh meat needs to be cut, the meat cutting rack is set up in the gap between the first conveyor belt and the second conveyor belt. Then, the fresh meat is transported to the gap between the first conveyor belt and the second conveyor belt by the first conveyor belt. The meat is then cut into equal weights by the reciprocating oscillating meat cutter, thereby achieving equal weight cutting of the fresh meat. When it is necessary to cut bones or ribs, the meat cutting rack is moved away from the frame, and then the chopping rack is set up in the gap between the first conveyor belt and the second conveyor belt. The bones or ribs are transported to the gap between the first conveyor belt and the second conveyor belt by the first conveyor belt. The bones are then cut by the reciprocating oscillating bone cutter, thereby achieving bone cutting and improving the efficiency of equal weight cutting of fresh meat and bones.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 14 The present invention will now be described in further detail.

[0036] One embodiment of the present invention relates to an energy-saving intelligent production line for equal-weight cutting of fresh meat, comprising a frame 1, on which a first conveyor belt 2 and a second conveyor belt 3 are mounted, and a blade changing unit, which includes a chopping frame 4 and a meat cutting frame 5. The chopping frame 4 is located on one side of the second conveyor belt 3 on the frame 1, and a reciprocating bone-chopping knife 6 is mounted on the chopping frame 4. The meat cutting frame 5 is located on the frame 1 at the gap between the first conveyor belt 2 and the second conveyor belt 3, and a reciprocating oscillating meat-cutting knife 7 is mounted on the meat cutting frame 5. When the bone-chopping knife 6 is in the cutting position, the bone-chopping knife 6 performs cutting operations on the bone; when the meat cutting knife 7 is in the cutting position, the meat cutting knife 7 performs cutting operations on the fresh meat.

[0037] Specifically, the intelligent production line for equal-weight cutting of fresh meat is a device capable of cutting fresh meat into multiple pieces of the same weight. The frame 1 is a frame body capable of mounting various components. A first conveyor belt 2 and a second conveyor belt 3 are mounted on the frame 1. Multiple clamping rollers 8 are rotatably mounted on the frame 1. Each clamping roller 8 is respectively clamped to its corresponding first conveyor belt 2 and second conveyor belt 3, thus tensioning the first and second conveyor belts 2 and 3. The first and second conveyor belts 2 and 3 can transport fresh meat in the same direction. The first and second conveyor belts 2 and 3 can transport objects. It is common knowledge in the art that conveyor belts 2 and 3 transport items, so it will not be elaborated here. The first conveyor belt 2 can transport whole pieces of fresh meat (or whole bones) to be cut, and the second conveyor belt 3 transports cut pieces of fresh meat (or bone pieces of equal weight). The meat cutting rack 5 has a blade groove that is compatible with the cutting blade. The outer wall of the meat cutting rack 5 is provided with a first driving member 9. The output end of the first driving member 9 passes through the blade groove and is connected to a meat cutting shaft. The meat cutting shaft is provided with a meat cutting blade 7. The first driving member 9 is a device that can drive the meat cutting shaft and the meat cutting blade 7 to reciprocate. It is preferably a motor. The meat cutting rack 5 and the chopping frame 4 are both rotatably mounted on the frame 1 via a driven shaft 10 and located at the first conveyor belt. At the connection point of the conveyor belt 2 and the second conveyor belt 3, a second driving component 11 is installed on the top of the chopping frame 4. The second driving component 11 is a device whose output end can perform reciprocating linear motion, preferably a hydraulic cylinder. The output end of the second driving component 11 is connected to a bone-chopping knife 6. A guide plate 12 is provided on the top of the frame 1 on one side of the first conveyor belt 2. A high-resolution camera (not shown in the figure) is provided on the top of the frame 1 on the top of the first conveyor belt 2. When the first conveyor belt 2 conveys a whole piece of fresh meat (or a whole bone), the guide plate 12 performs a certain guiding operation on the fresh meat (or the whole bone), so that the fresh meat (or the whole bone) is located in the middle position of the first conveyor belt 2. Simultaneously, the whole piece of fresh meat on the first conveyor belt 2 ( Or a whole bone) is scanned and identified by a high-resolution camera. The camera obtains data such as the size and shape of the meat (or bone) in real time. The data is then transmitted to the control algorithm center for processing. Based on the quality, shape, weight and other factors of the meat (or bone), the intelligent control machine performs precise cutting. By monitoring and adjusting the cutting quality, the weight of the meat (or bone) can be kept within a fixed range, thus achieving equal weight cutting of fresh meat (or bone). The intelligent control machine is interconnected with the first drive component 9 and the second drive component 11. The intelligent control machine issues cutting commands to the first drive component 9 or the second drive component 11.The chopping frame 4 has a first sliding groove 13, and the cleaver 6 is slidably installed in the first sliding groove 13. The meat cutting rack 5 has a second sliding groove 14, and the second sliding groove 14 and the cleaver 6 are slidably adapted to each other. The chopping frame 4 has a connecting groove 22, and the connecting groove 22 and the meat cutting rack 5 are mutually abutting and supporting each other. A first support rod 15 is provided on one side of the first conveyor belt 2 on the frame 1, and the first support rod 15 and the meat cutting rack 5 are mutually abutting and adapted to each other. A second support rod 16 is provided on one side of the second conveyor belt 3, and the second support rod 16 and the chopping frame 4 are fitted together and abut against each other; a third drive component 17 is mounted on each of the two side walls of the frame 1 at the connection position of the first conveyor belt 2 and the second conveyor belt 3 via a motor mount, and the output end of each third drive component 17 is connected to a drive gear 18. A driven gear 19 is mounted on each of the two driven shafts 10, and the two drive gears 18 are respectively meshed with their corresponding driven gears 19.

[0038] When the first conveyor belt 2 transports fresh meat to the connection point of the first conveyor belt 2 and the second conveyor belt 3, and after the first conveyor belt 2 transports the fresh meat to the appropriate cutting position (that is, after the high-resolution camera, control algorithm center, and intelligent control machine analyze the various cutting positions of the fresh meat), the first conveyor belt 2 and the second conveyor belt 3 stop moving. The first drive component 9 then drives the meat cutter 7 via the meat cutting shaft to cut the fresh meat at the designated cutting position. The meat cutter 7 passes precisely through the gap between the first conveyor belt 2 and the second conveyor belt 3, thus achieving the cutting operation of the fresh meat by the meat cutter 7. The gap between the conveyor belts 3 and the thickness of the meat cutter 7 are the same, which makes the meat cutter 7 cut the fresh meat more accurately. The meat cutter 7 first cuts the fresh meat, and then the meat cutter 7 swings into the groove in the middle of the meat cutting frame 5, which facilitates the next cutting of the fresh meat. Then the first conveyor belt 2 and the second conveyor belt 3 transport the fresh meat again. When the first conveyor belt 2 and the second conveyor belt 3 carry the fresh meat to the next cutting position, the meat cutter 7 performs a second cutting operation on the fresh meat. By repeating this process, a whole piece of fresh meat can be cut into multiple pieces of fresh meat of the same weight, thereby achieving equal weight cutting of fresh meat.

[0039] The existing meat cutter 7 can only cut fresh meat. However, in actual use, not only fresh meat needs to be cut, but also bones and ribs. Since the rotating meat cutter 7 cannot cut bones or ribs, it is necessary to change the blade when cutting bones or ribs. After the meat cutter 7 has finished cutting the fresh meat, when it is necessary to cut bones or ribs, the meat cutter 7 needs to be replaced with a bone-chopping knife 6. Simultaneously, the third drive component 17 (a device with a reciprocating output, preferably a motor) is activated to drive the drive gear 18. Because the drive gear 18 and its corresponding driven gear 19 are... The intermeshing arrangement causes the driving gear 18 to drive the driven gear 19, which meshes with it, to rotate 90 degrees. The driven gear 19 then drives the driven shaft 10 to rotate 90 degrees. The driven shaft 10 causes the meat cutting frame 5 to rotate out of the docking groove 22 on the chopping frame 4. After the meat cutting frame 5 rotates 90 degrees, it rotates onto the first support rod 15, allowing the first support rod 15 to provide auxiliary support for the meat cutting frame 5, thus freeing it from the cutting position on the frame 1. Meanwhile, the driven gear 19, through the driven shaft 10, drives the chopping frame 4 to rotate 90 degrees, causing the chopping frame 4 to rotate from the second support rod 16 to the second sliding groove 14 on the meat cutting frame 5. This allows the chopping frame 4 to drive the bone-chopping knife 6 to rotate via the second driving component 11. The movement of the cleaver 6 by 90 degrees allows it to rotate to the position where the first conveyor belt 2 and the second conveyor belt 3 connect, enabling the cleaver 6 to cut the bone or ribs. The second drive component 11 drives the cleaver 6 to slide a short distance along the trajectory of the first slide groove 13. Simultaneously, the cleaver 6 slides a short distance along the second slide groove 14 on the meat cutting rack 5, allowing the second slide groove 14 on the meat cutting rack 5 to perform sliding limit operation on the cleaver 6. As those skilled in the art will know, to ensure the stability of cutting the bone or ribs along the first conveyor belt 2 and the second conveyor belt 3, a fourth drive component 20 is provided on the side walls of both the meat cutting rack 5 and the chopping frame 4. It is a device whose output end can perform reciprocating linear motion (preferably a cylinder). Each output end of the fourth drive component 20 is connected to a clamping plate 21. When it is necessary to cut the rod or rib, the rod or rib is placed on the first conveyor belt 2 and then conveyed by the first conveyor belt 2. When the rod or rib passes through the high-resolution camera, the high-resolution camera scans and identifies the rod or rib to be cut, and obtains data such as the size and shape of the rod or rib in real time. Then, the obtained data is transmitted to the control algorithm center for processing. Based on the mass, shape, weight and other factors of the rod or rib, the machine is intelligently controlled to perform precise cutting.By monitoring and adjusting the cutting quality, the cutting weight of the pork bones or spare ribs can be kept within a fixed range, thus achieving equal-weight cutting of the pork bones or spare ribs. The intelligent control machine and the second drive unit 11 are interconnected. The intelligent control machine issues cutting commands to the second drive unit 11. When the first conveyor belt 2 transports the fresh meat to the connection position of the first conveyor belt 2 and the second conveyor belt 3, and when the first conveyor belt 2 transports the pork bones or spare ribs to the appropriate cutting position (that is, the various cutting positions of the pork bones or spare ribs are analyzed by the high-resolution camera, the control algorithm center, and the intelligent control machine), the first conveyor belt 2 and the second conveyor belt 3 stop moving. The fourth drive unit 20 drives the clamping plate 21 to move closer to the pork bones or spare ribs. One end moves, causing the clamping plate 21 to clamp and position the bone or rib. Then, the second driving component 11 drives the cleaver 6 to cut the bone or rib, thus achieving the cutting operation of the bone or rib. After the cleaver 6 has finished cutting the bone or rib, the second driving component 11 drives the cleaver 6 to a suitable cutting position to facilitate the next cutting operation of the bone or rib, or if it is detected that the bone or rib is not completely cut, the cleaver 6 performs a second cutting operation on the bone or rib until the bone or rib is completely cut. The above operation is repeated, thus achieving the equal weight cutting operation of the bone or rib, until the bone or rib is cut into multiple bone pieces of equal weight.

[0040] When fresh meat needs to be cut, the cleaver 6 needs to be replaced with a meat cutter 7. The second drive unit 11 drives the cleaver 6 to slide out of the second groove 14 on the second support rod 16. Simultaneously, the third drive unit 17 is activated to drive the drive gear 18 to rotate. The drive gear 18 drives the driven gear 19, which meshes with it, to rotate 90 degrees. The driven gear 19 drives the chopping frame 4 to rotate 90 degrees through the driven shaft 10. The chopping frame 4 slides from the second groove 14 on the meat cutting rack 5 to the second support rod 16, so that the second support rod 16 provides auxiliary support for the chopping frame 4. Simultaneously, the driven gear 19 drives the driven shaft 10 to rotate 90 degrees. The driven shaft 10 drives the meat cutting rack 5 to rotate 90 degrees from the first support rod 15, so that the meat cutting rack 5 rotates to the mating position with the chopping frame 4. The meat cutting rack 5 drives the meat cutter 7 to rotate to the connection position between the first conveyor belt 2 and the second conveyor belt 3, so that the meat cutter 7 can cut the fresh meat.

[0041] The shortcoming of existing technology is that the intelligent production line for heavy cutting of fresh meat can only cut fresh meat. However, some of the meat to be cut contains bones, which requires bone cutting. When cutting bones, existing technology requires an additional production line.

[0042] The beneficial effects of this embodiment are as follows: When fresh meat needs to be cut, the meat cutting rack 5 is set up in the gap between the first conveyor belt 2 and the second conveyor belt 3. Then, the fresh meat is transported to the gap between the first conveyor belt 2 and the second conveyor belt 3 by the first conveyor belt 2. The meat is then cut into equal weights by the reciprocating oscillating meat cutter 7, thereby achieving equal weight cutting of the fresh meat. When it is necessary to cut ribs or bones, the meat cutting rack 5 is moved off the rack, and then the chopping rack 4 is set up in the gap between the first conveyor belt 2 and the second conveyor belt 3. The ribs or bones are transported to the gap between the first conveyor belt 2 and the second conveyor belt 3 by the first conveyor belt 2. The ribs are then cut into equal weights by the reciprocating oscillating bone cutter 6, thereby achieving cutting of the ribs and improving the efficiency of equal weight cutting of fresh meat and ribs.

[0043] In another embodiment of the present invention, the meat cutting rack 5 is also provided with a docking groove 22. Limiting units are provided in the docking grooves 22 of both the meat cutting rack 5 and the chopping frame 4. Slots 23 are provided on both the meat cutting rack 5 and the chopping frame 4. Limiting hooks 24 are rotatably installed in each slot 23. The limiting hooks 24 and the inner wall of the slot 23 are connected by a rotatably connected tension spring 25. A return plate 26 that is adapted to and abuts against the meat cutting rack 5 is provided in the docking groove 22 of the chopping frame 4. The docking groove 22 of the meat cutting rack 5 is provided with... A return plate 26 is provided that is adapted to and abuts against the chopping frame 4. The return plate 26 is connected to the corresponding chopping frame 4 and meat cutting rack 5 by return springs 27. Hook plates 28 are provided in the docking grooves 22 on the chopping frame 4 and meat cutting rack 5. The end of the hook plate 28 away from the return plate 26 has a hook surface structure. An unlocking plate 29 is rotatably installed on the hook plate 28. The unlocking plate 29 and the hook plate 28 abut against each other to form a triangular shape. A flat block 30 is provided on the side of the unlocking plate 29 away from the hook surface structure of the hook plate 28.

[0044] Specifically, because the connection and positioning between the meat cutting rack 5 and the chopping frame 4 are unstable after rotation and repositioning, in this embodiment, when the third driving member 17 meshes with the driving gear 18 and the driven gear 19, the driven gear 19 drives the meat cutting rack 5 to rotate into the docking groove 22 on the chopping frame 4 via the driven shaft 10 (or the driven shaft 10 drives the chopping frame 4 to rotate into the docking groove 22 on the meat cutting rack 5), the limiting hook 24 on the meat cutting rack 5 extends into the docking groove 22 on the chopping frame 4 (or the limiting hook 24 on the chopping frame 4 extends into the docking groove 22 on the meat cutting rack 5). Under the pushing force of the tension spring 25, the limiting hook 24 and the hook surface structure of the hook plate 28 abut against each other. The limiting hook 24 pushes the unlocking plate 29 to rotate at a certain angle on the hook plate 28 until the limiting hook 24 and the hook plate 28 hook each other tightly (e.g., Figure 7 and Figure 8 As shown), simultaneously, the meat cutting rack 5 compresses the return plate 26 on the chopping frame 4, causing the return spring 27 on the return plate 26 to be in a compressed state. Under the rebound action of the return spring 27, the return spring 27 provides a rebound force to the return plate 26 and the meat cutting rack 5, so that the meat cutting rack 5 can be stably connected to the chopping frame 4 (or the chopping frame 4 compresses the return plate 26 on the meat cutting rack 5, causing the return spring 27 on the return plate 26 to be in a compressed state. Under the rebound action of the return spring 27, the return spring 27 provides a rebound force to the return plate 26 and the chopping frame 4, so that the chopping frame 4 can be stably connected to the meat cutting rack 5). Thus, after the chopping frame 4 and the meat cutting rack 5 rotate 90 degrees, the cleaver 6 and the meat cutter 7 on the chopping frame 4 and the meat cutting rack 5 can cut the bones or fresh meat, thereby improving the stability of the connection after the chopping frame 4 and the meat cutting rack 5 rotate and change position, and thus improving the cutting quality of the bones or fresh meat.

[0045] When the chopping frame 4 and the meat cutting rack 5 need to rotate 90 degrees, and the hook plate 28 and the limiting hook 24 need to disengage, the chopping frame 4 and the meat cutting rack 5 drive the limiting hook 24 to rotate towards the end closer to the return plate 26. This causes the chopping frame 4 and the meat cutting rack 5 to compress the return plate 26 and the return spring 27, putting them in a compressed state. Simultaneously, the limiting hook 24 pushes the unlocking plate 29 to rotate until the unlocking plate 29 and the flat block 30 are pressed together. The limiting hook 24 slides on the unlocking plate 29 to its end, hooking the end of the unlocking plate 29 (e.g., ...). Figure 9 (As shown), then the chopping frame 4 and the meat cutting rack 5 drive the limiting hook 24 to rotate away from the return plate 26. Under the rebound action of the return spring 27, the return plate 26 rotates to the initial state. Simultaneously, the limiting hook 24 pulls the unlocking plate 29 to rotate and press against the surface structure of the hook plate 28, so that the unlocking plate 29 and the hook plate 28 abut against each other in a triangular shape. Then the hook plate 28 slides over the surface of the unlocking plate 29, thereby realizing the mutual disengagement and unlocking of the limiting hook 24 and the hook plate 28, thereby performing the mutual exchange between the meat cutting rack 5 and the chopping frame 4.

[0046] Furthermore, a clamping plate 31 is provided on the frame 1 at the bottom side of the first conveyor belt 2, and the top of the clamping plate 31 is fitted to the curved surface of the first conveyor belt 2; a material leakage channel is provided inside the clamping plate 31, and a collection box 32 is provided at the end of the material leakage channel on the clamping plate 31.

[0047] Specifically, when the first conveyor belt 2 is conveying a whole piece of fresh meat, the top surfaces of the first conveyor belt 2 and the pressing plate 31 are fitted together and pressed against each other. After the meat cutter 7 cuts the fresh meat, the first conveyor belt 2 and the pressing plate 31 move together and press against each other. The pressing plate 31 scrapes off the meat scraps or liquids (such as blood or thawing water) remaining on the first conveyor belt 2. This allows the pressing plate 31 to scrape off the meat scraps and other impurities remaining on the first conveyor belt 2. The meat scraps and other impurities remaining on the first conveyor belt 2 fall into the collection box 32 through the leakage channel. The collection box 32 can collect the meat scraps and other impurities remaining on the first conveyor belt 2, so that the first conveyor belt 2 can carry out a clean conveying operation of the whole piece of fresh meat.

[0048] In another embodiment of the present invention, the bottom sides of the frame 1 located on the side of the second conveyor belt 3 are provided with slots 33. A support plate 34 is slidably installed between the slots 33 on both sides of the frame 1. A flat plate 44 is installed on the outside of the slots 33 on the frame 1. The flat plate 44 and the support plate 34 are connected by a fifth driving member 35. Parallel straight rods 36 are rotatably installed at the four right-angle positions on the top of the support plate 34. A square plate 37 is rotatably installed at the end of each of the four straight rods 36. A docking plate 38 is installed on the top of the square plate 37 near the abutment plate 31. A V-shaped groove 39 is provided on the docking plate 38 to match the cutting part of the bone cleaver 6.

[0049] Specifically, when the first conveyor belt 2 conveys the bones or ribs, during the actual conveying process, when the bones or ribs move to the gap between the first conveyor belt 2 and the second conveyor belt 3, due to the irregular shape of the bones or ribs, they may get stuck in the gap between the first conveyor belt 2 and the second conveyor belt 3. As a result, the first conveyor belt 2 and the second conveyor belt 3 cannot convey the bones or ribs to the appropriate cutting position. Furthermore, when the bone-chopping knife 6 cuts the bones or ribs, the bones or ribs are subjected to the downward cutting force of the bone-chopping knife 6. This cutting force acts on the first conveyor belt 2 and the second conveyor belt 3, which can easily cause damage to the first conveyor belt 2 and the second conveyor belt 3. In this embodiment, when the meat cutter 7 on the frame 1 is replaced with the bone-chopping knife 6, the fifth drive component 35 (the fifth drive component 35 is a device with a reciprocating linear motion output end, preferably a hydraulic cylinder) is activated to push the support plate. The support plate 34 moves towards the end closer to the clamping plate 31. The support plate 34 drives the straight rod 36 to move towards the end closer to the clamping plate 31. The straight rod 36 drives the square plate 37 to move towards the end closer to the clamping plate 31. The square plate 37 drives the mating plate 38 to move towards the end closer to the clamping plate 31. When the square plate 37 and the mating plate 38 are simultaneously pressed against the clamping plate 31, the support plate 34 continues to move towards the end closer to the clamping plate 31. Under the pressing action of the clamping plate 31 against the square plate 37 and the mating plate 38... The square plate 37 and the mating plate 38 slide along the trajectory of the abutting plate 31 towards one end of the first conveyor belt 2, and the straight rod 36 rotates until the supporting plate 34 moves to a position where it abuts against the abutting plate 31. The straight rod 36 pushes the square plate 37 upward, and the square plate 37 drives the mating plate 38 to slide upward along the gap between the first conveyor belt 2 and the second conveyor belt 3, so that the mating plate 38 can perform a certain sealing operation on the gap between the first conveyor belt 2 and the second conveyor belt 3 (e.g., Figure 13As shown), when the first conveyor belt 2 conveys the bones or ribs, the gap between the first conveyor belt 2 and the second conveyor belt 3 is blocked by the connecting plate 38, allowing the bones or ribs to slide past the connecting plate 38 without getting stuck in the gap. When the bone-chopping knife 6 cuts the bones or ribs, it cuts them on the connecting plate 38, allowing the connecting plate 38 to support the bones or ribs. The cutting force of the bone-chopping knife 6 acts on the connecting plate 38, and the V-groove 39 on the connecting plate 38 and the bone-chopping knife 6 are mutually adapted, allowing the bone-chopping knife 6 to cut the bones or ribs in one go without multiple cuts, thus improving the efficiency of the bone-chopping knife. To improve the cutting efficiency of the 6 pairs of bones or ribs, the connecting plate 38 in this embodiment has three effects: First, the connecting plate 38 seals the gap between the first conveyor belt 2 and the second conveyor belt 3, allowing the bones or ribs to slide smoothly through the connecting plate 38 without getting stuck in the gap. Second, the connecting plate 38 can support the cutting force of the cleaver 6 on the bones or ribs, preventing damage to the first conveyor belt 2 and the second conveyor belt 3 from the force of the bones or ribs during cutting. Finally, the V-groove 39 on the connecting plate 38 and the cleaver 6 are mutually adapted, allowing the cleaver 6 to cut the bones or ribs in one go without multiple cutting operations, thereby improving the cutting efficiency of the cleaver 6 on the bones or ribs.

[0050] When the cleaver 6 on frame 1 is replaced with a meat cutter 7, the fifth drive unit 35 is activated to push the support plate 34 and the clamping plate 31 apart. The support plate 34 drives the straight rod 36 to move away from the clamping plate 31. The straight rod 36 rotates between the square plate 37 and the support plate 34, causing the straight rod 36 to drive the square plate 37 and the docking plate 38 to slide along the side wall of the clamping plate 31. The gap between the first conveyor belt 2 and the second conveyor belt 3 limits the docking plate 38, causing the straight rod 36 to tilt and rotate towards the clamping plate 31 between the support plate 34 and the square plate 37 until the docking plate 38 slides out of the gap between the first conveyor belt 2 and the second conveyor belt 3. The docking plate 38 and the square plate 37 then press against the clamping plate 31, while the support plate 34 continues to drive the docking plate 38 and the square plate 37 to a position where they are separated from the clamping plate 31 (e.g., ...). Figure 12 As shown), to prevent the square plate 37 and the docking plate 38 from affecting the cutting of fresh meat by the meat cutter 7, and to provide a cutting path for the meat cutter 7 to cut fresh meat.

[0051] In another embodiment of the present invention, a receiving groove 40 is provided on the top side of the docking plate 38 near the first conveyor belt 2. An auxiliary plate 41 is rotatably installed in the receiving groove 40 via an auxiliary shaft. The auxiliary plate 41 and the receiving groove 40 are connected by a return spring 42. A through groove 43 is provided on the abutting plate 31. The through groove 43 and the material leakage channel are interconnected. The through groove 43 and the receiving groove 40 are interconnected.

[0052] Specifically, when the meat cleaver 7 on the frame 1 is replaced with a bone-chopping knife 6, the fifth drive unit 35 is activated to push the support plate 34 towards the end near the clamping plate 31. The support plate 34, through the straight rod 36, drives the square plate 37 and the docking plate 38 towards the end near the clamping plate 31 until the square plate 37 and the docking plate 38 simultaneously press against the clamping plate 31. The docking plate 38 then drives the auxiliary plate 41 to press against the clamping plate 31. Under the pressing action of the clamping plate 31, the auxiliary plate 41 rotates into the receiving groove 40. The auxiliary plate 41 compresses the return spring 42, causing the return spring to be in a compressed state. When the docking plate 38 moves into the gap between the first conveyor belt 2 and the second conveyor belt 3, the auxiliary plate 41 loses the pressing force of the clamping plate 31. Under the rebound action of the return spring 42, the auxiliary plate 41 rotates, causing the auxiliary plate 41 to press against the first conveyor belt 2 and the docking plate 38. The connection operation is fixed, and when the cleaver 6 cuts the bone or rib, the debris generated during the cutting enters the auxiliary plate 41, so that the auxiliary plate 41 guides the debris. When the bone or rib is pressed against the auxiliary plate 41, the bone or rib will squeeze the auxiliary plate 41. Under the elastic action of the return spring 42, the bone or rib will bounce up at the auxiliary plate 41, further preventing the bone or rib from getting stuck at the docking plate 38 and the first conveyor belt 2, thereby improving the stability of the bone or rib cutting. When the cleaver 6 is replaced with the meat cutter 7 on the frame 1, the fifth drive component 35 drives the square plate 37 and the docking plate 38 to slide along the side wall of the abutment plate 31 through the support plate 34 and the straight rod 36. After the auxiliary plate 41 is separated from the first conveyor belt 2, the through groove 43 and the receiving groove 40 are connected to each other (e.g. Figure 14 As shown in the figure, the debris in the receiving groove 40 enters the collection box 32 through the through groove 43, and the debris is collected by the collection box 32.
