Description

Technical Field

[0001] This invention relates to the field of meat processing technology, and in particular to a machine for cutting mutton carcasses. Background Technology

[0002] In frozen meat processing plants, reciprocating wire saws are typically used to initially cut frozen lamb carcasses into larger pieces such as ribs, forelegs, and hind legs, facilitating subsequent finer cutting. However, existing wire saw equipment for cutting meat has the following problems: during the cutting process of frozen meat, ice chips and meat scraps easily adhere to the surface of the wire saw blade. Furthermore, when cutting harder bones such as leg bones, spine, and skulls, not only does a large amount of bone meal adhere, but the wire saw blade may also break, affecting production safety. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing wire saw blades, which have a large number of impurities adhering to their surface when cutting meat, and to propose a meat carcass cutting device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a mutton carcass cutting device, including a base and a worktable arranged parallel to the base. The worktable is located above the base. A frame is fixedly connected to one side of the worktable. Slide rails are vertically fixed to both the upper and lower sides of the frame. Sliding seats are slidably fitted on the slide rails. A mounting plate is fixedly connected to the sliding seats. A pipe is rotatably mounted on the bottom surface of the mounting plate. A connecting structure is provided inside the pipe for connecting a wire saw blade. A transmission gear is rotatably mounted on one side of the mounting plate. An end face gear is fixedly connected to the outer wall of the pipe. The transmission gear matches the end face gear. A rack is vertically fixed to the side wall of the frame. The rack matches the transmission gear.

[0005] Preferably, the wire saw blade passes through the worktable.

[0006] Preferably, the frame is provided with a drive structure for driving the wire saw blade to reciprocate. The drive structure includes two pulleys, which are rotatably mounted on the frame. A motor is mounted on the outer wall of the frame. One of the pulleys is fixedly connected to the output shaft of the motor. A belt is fitted on the two pulleys, and the two ends of the belt are fixed to two mounting plates respectively.

[0007] Preferably, the connection structure includes a drive shaft, which is rotatably mounted inside the pipe fitting. A winding wheel is fixedly connected to the shaft body of the drive shaft, and the end of the wire saw blade is fixed and wound around the winding wheel.

[0008] Preferably, a guide sleeve is fixedly connected to the end face of the pipe fitting, and the wire saw blade passes vertically through the guide sleeve so that the wire saw blade and the pipe fitting are in a coaxial state.

[0009] Preferably, a small gear is coaxially fixed to the end face of the winding wheel, and a large gear is rotatably mounted on the inner wall of the tube. The large gear matches the small gear, and a spring is installed on the inner wall of the tube to apply elastic force to the large gear.

[0010] Preferably, the pipe wall of the fitting has a groove, and one end of the drive shaft extends into the groove and is fixedly connected to a square insert.

[0011] Preferably, a square-outer, round-inner insertion tube is slidably fitted inside the groove, and a ratchet is rotatably fitted inside the insertion tube. The ratchet has a square insertion hole, and the insertion rod is slidably fitted inside the insertion hole. Multiple pawls are hinged to the inner wall of the insertion tube, and the pawls match the ratchet.

[0012] Preferably, an end cap is threaded onto the end face of the groove.

[0013] The mutton carcass cutting device proposed in this invention has the following advantages: During the cutting process of the mutton carcass, the wire saw blade rotates while making linear reciprocating motion. The centrifugal force generated during the rotation of the wire saw blade is used to clean the impurities such as ice crystals, meat scraps, and bone meal attached to the surface, thereby ensuring the cleanliness of the wire saw blade during operation and preventing impurities on the surface of the wire saw blade from contaminating the cut meat.

[0014] When a wire saw blade breaks unexpectedly during cutting, the elastic potential energy of the spring is converted into kinetic energy that drives the large gear to rotate. The rotation of the large gear drives the small gear to rotate, and the rotation of the small gear drives the winding wheel to rotate to wind the wire saw blade, thereby preventing the wire saw blade from breaking during operation and causing the wire saw blade to swing wildly and cause injury.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figures 1-4A mutton carcass cutting device includes a base 1 and a worktable 2 arranged parallel to the base 1. The worktable 2 is located above the base 1. A frame 3 is fixedly connected to one side of the worktable 2. Slide rails 10 are vertically fixed to both the upper and lower sides of the frame 3. Sliding seats 9 are slidably fitted on the slide rails 10. Mounting plates 8 are fixedly connected to the sliding seats 9. Pipe fittings 14 are rotatably mounted on the bottom surface of the mounting plates 8. A connecting structure is provided inside the pipe fittings 14 for connecting wire saw blades 7. A drive structure is provided on the frame 3 to drive the wire saw blades 7 to reciprocate. The drive structure includes two pulleys 5, which are rotatably mounted on the frame 3. A motor 4 is mounted on the outer wall of the frame 3. One of the pulleys 5 is fixedly connected to the output shaft of the motor 4. A belt 6 is fitted on the two pulleys 5. The two ends of the belt 6 are respectively fixed to the two mounting plates 8.

[0030] When cutting the sheep carcass, the motor 4 is powered on and drives the pulley 5 to rotate back and forth. During the back and forth rotation of the pulley 5, the belt 6 will drive the mounting plate 8 to move back and forth in a straight line, so that the wire saw blade 7 connected in the pipe 14 moves back and forth in the vertical direction, thereby cutting the sheep carcass on the workbench 2.

[0031] During the reciprocating motion of the mounting plate 8, the sliding seat 9 slides back and forth along the slide rail 10 to guide the mounting plate 8 and prevent its movement trajectory from deviating.

[0032] like Figures 4-8 As shown, the wire saw blade 7 passes through the workbench 2, and a guide sleeve 19 is fixedly connected to the end face of the pipe fitting 14. The wire saw blade 7 passes vertically through the guide sleeve 19. A transmission gear 12 is rotatably installed on one side of the mounting plate 8. An end face gear 13 is fixedly connected to the outer wall of the pipe fitting 14. The transmission gear 12 matches the end face gear 13. A rack 11 is vertically fixed to the side wall of the frame 3. The rack 11 matches the transmission gear 12.

[0033] During the reciprocating motion of the mounting plate 8, the rack 11 drives the transmission gear 12 to rotate, the transmission gear 12 drives the end face gear 13 to rotate, the end face gear 13 rotates, and the pipe fitting 14 rotates. The rotation of the pipe fitting 14 causes the wire saw blade 7 to rotate within the guide sleeve 19. During the rotation of the wire saw blade 7, impurities such as ice chips, meat scraps, and bone meal attached to its surface will be thrown off the wire saw blade 7 under the action of centrifugal force, thereby achieving the purpose of cleaning the wire saw blade 7 and preventing the long-term adhesion of impurities such as ice chips, meat scraps, and bone meal, which would lead to bacterial growth.

[0034] like Figures 9-11As shown, the connection structure includes a drive shaft 17, which is rotatably mounted inside the pipe fitting 14. A winding wheel 20 is fixedly connected to the shaft of the drive shaft 17. The end of the wire saw blade 7 is fixed and wound around the winding wheel 20 so that the wire saw blade 7 and the pipe fitting 14 are in a coaxial state. A small gear 18 is coaxially fixed to the end face of the winding wheel 20. A large gear 15 is rotatably mounted on the inner wall of the pipe fitting 14. The large gear 15 matches the small gear 18. A spring 16 is installed on the inner wall of the pipe fitting 14 to apply elastic force to the large gear 15.

[0035] When the wire saw blade 7 breaks accidentally during the cutting process, the elastic potential energy of the spring 16 will be converted into kinetic energy to drive the large gear 15 to rotate. When the large gear 15 rotates, it will drive the small gear 18 to rotate. The rotation of the small gear 18 will drive the winding wheel 20 to rotate to wind up the wire saw blade 7, thereby preventing the wire saw blade 7 from breaking during operation and causing the wire saw blade 7 to swing randomly and cause injury.

[0036] like Figure 11 and Figure 12 As shown, a groove 22 is provided on the wall of the pipe fitting 14. One end of the drive shaft 17 extends to the groove 22 and is fixedly connected to a square insertion rod 21. An insertion tube 23 with an outer square and inner round shape is slidably fitted inside the groove 22. A ratchet 25 is rotatably fitted inside the insertion tube 23. A square insertion hole 26 is provided on the ratchet 25. The insertion rod 21 is slidably fitted inside the insertion hole 26. Multiple pawls 24 are hinged on the inner wall of the insertion tube 23. The pawls 24 match the ratchet 25. An end cap 27 is threaded onto the end face of the groove 22.

[0037] The cooperation of the pawl 24 and the ratchet 25 allows the drive shaft 17 to rotate only under the drive of the spring 16. During the operation of the wire saw blade 7, the pawl 24 and the ratchet 25 lock the drive shaft 17 in one direction to ensure that the wire saw blade 7 is always in a taut state.

[0038] Working principle: When cutting the sheep carcass, the motor 4 is energized, driving the pulley 5 to reciprocate. During this reciprocating rotation, the pulley 5 drives the belt 6 to reciprocate, which in turn drives the mounting plate 8 to reciprocate linearly. This causes the wire saw blade 7 connected inside the pipe fitting 14 to reciprocate vertically, thereby cutting the sheep carcass on the workbench 2. During the reciprocating motion of the mounting plate 8, the sliding seat 9 slides back and forth along the slide rail 10, guiding the mounting plate 8 to prevent deviation from its trajectory.

[0039] During the reciprocating motion of the mounting plate 8, the rack 11 drives the transmission gear 12 to rotate, the transmission gear 12 drives the end face gear 13 to rotate, the end face gear 13 rotates, and the pipe fitting 14 rotates. The rotation of the pipe fitting 14 causes the wire saw blade 7 to rotate within the guide sleeve 19. During the rotation of the wire saw blade 7, impurities such as ice chips, meat scraps, and bone meal attached to its surface will be thrown off the wire saw blade 7 under the action of centrifugal force, thereby achieving the purpose of cleaning the wire saw blade 7 and preventing the long-term adhesion of impurities such as ice chips, meat scraps, and bone meal, which would lead to bacterial growth.

[0040] When the wire saw blade 7 breaks accidentally during the cutting process, the elastic potential energy of the spring 16 will be converted into kinetic energy to drive the large gear 15 to rotate. When the large gear 15 rotates, it will drive the small gear 18 to rotate. The rotation of the small gear 18 will drive the winding wheel 20 to rotate to wind up the wire saw blade 7, thereby preventing the wire saw blade 7 from breaking during operation and causing the wire saw blade 7 to swing randomly and cause injury.

[0041] The cooperation of the pawl 24 and the ratchet 25 allows the drive shaft 17 to rotate only under the drive of the spring 16. During the operation of the wire saw blade 7, the pawl 24 and the ratchet 25 lock the drive shaft 17 in one direction to ensure that the wire saw blade 7 is always in a taut state.

[0042] Compared to existing technologies, the present invention provides a mutton carcass cutting device in which the wire saw blade 7 rotates while making linear reciprocating motion during the cutting process. This utilizes the centrifugal force generated during the rotation of the wire saw blade 7 to clean impurities such as ice crystals, meat scraps, and bone meal adhering to the surface, ensuring the cleanliness of the wire saw blade 7 during operation and preventing impurities on the surface of the wire saw blade 7 from contaminating the cut meat.

[0043] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
