Description

Technical Field

[0001] This invention relates to the field of meat processing technology, and more specifically, to a beef and mutton cutting device and its processing method. Background Technology

[0002] Traditional beef and mutton cutting equipment in the present technology generally adopts a rigid configuration of the conveyor system in its structural design, lacking the ability to dynamically adjust according to the actual thickness of the meat. As a result, the equipment cannot achieve a suitable conveying effect when dealing with meat pieces of significantly different thicknesses. When the meat pieces to be processed are thick, the gap between the fixed-height conveyor mechanism and the conveyor platform is relatively small. When the thick meat pieces enter the conveyor channel, they are subjected to excessive compression by the conveyor mechanism. Excessive holding force can not only cause surface deformation of the meat pieces and even damage the internal structure, but may also cause premature leakage of meat juices due to forced compression, affecting the sensory quality and nutritional value of the finished meat. More seriously, excessive compression can also increase the frictional resistance between the meat pieces and the conveyor mechanism, causing a sharp increase in the load on the conveyor drive system and even triggering motor overload protection. In cases of machine downtime, when the meat pieces to be processed are thin, there is a large gap between the fixed-height conveyor mechanism and the surface of the thin meat pieces. The conveyor mechanism cannot apply sufficient holding force to ensure the positional stability of the meat pieces during the conveying process. Under the reaction force of the cutting blade, the thin meat pieces are prone to lateral slippage or longitudinal displacement, causing the cutting path to deviate from the predetermined position, resulting in cutting size errors or even processing defects such as off-center or crooked cuts. This problem of unstable processing quality caused by poor thickness adaptability restricts the equipment's ability to process raw meat of different specifications. It forces operators to frequently change special tooling fixtures or perform complex manual positioning operations for meat pieces of different thicknesses. This not only reduces production efficiency and increases labor intensity, but also further exacerbates the fluctuation of product quality due to the uncertainty of human operation.

[0003] Secondly, traditional beef and mutton cutting equipment exhibits unsatisfactory cutting results when processing softer meats. Soft meats, due to their loosely arranged muscle fibers, high fat content, and relatively weak connective tissue, possess lower mechanical strength and poor shape retention at room temperature. When the cutting blade applies pressure to the surface of a soft meat block at a fixed speed, the meat lacks sufficient structural rigidity to resist the cutting force. The meat block undergoes significant elastic deformation in front of the blade, or even recoils entirely, preventing the blade from cutting along the intended path. Furthermore, the cutting blade cannot adaptively adjust the pressure and position on the meat block according to its firmness during the cutting process. When the blade contacts the surface of the soft meat block and prepares to cut, the... Lacking an effective mechanism for stabilizing the meat's posture, soft meat pieces will slide laterally or deflect longitudinally under the initial contact force of the blade. The spatial position and orientation angle of the meat piece will deviate randomly from the blade's predetermined cutting path, causing the actual entry point of the blade to deviate from the design position. This results in uneven width of the cut meat strips or pieces or tilted cutting angles. Traditional equipment blade structures typically only provide a simple vertical downward cutting action. During the downward cutting process, the blade cannot exert a restraining force on the meat piece to suppress its tendency to move. The soft meat piece is in an unstable position throughout the entire cutting stroke. As the blade gradually enters, the unbalanced cutting force on the meat piece will drive it to rotate or overturn around a certain fulcrum, further exacerbating the deviation of the cutting path.

[0013] Preferably, the outer wall of the fixed cylinder is slidably connected with an upper inclined ring and a lower inclined ring. The upper end of the upper inclined ring is connected to two short rods, and the other end of the short rods is connected to an upper pressure ring. The side wall of the lower inclined ring is provided with two long rods, and the other end of the long rods is connected to a lower pressure ring. The surfaces of the two upper pressure rings are fitted with upper pressure plates, and the surfaces of the two lower pressure rings are fitted with lower pressure plates. The upper inclined ring is used in conjunction with the corresponding upper abutment rod, and the lower inclined ring is used in conjunction with the corresponding lower abutment rod.

[0014] This invention provides a method for cutting and processing beef and mutton, comprising the following steps: Before cutting a new batch of meat, the operator needs to pre-adjust the downward conveying mechanism according to the actual thickness of the meat. The operator presses the upper and lower pressure plates simultaneously. The upper pressure plate moves down, driving the upper inclined ring down through the upper pressure ring and short rod. The lower pressure plate moves up, driving the lower inclined ring up through the lower pressure ring and long rod. The two inclined rings squeeze the corresponding abutment rods, causing them to move outward. The abutment rods drive the insertion rod to slide along the limiting groove and disengage from the locking state of the adjustment rod surface groove through the cross plate. At this time, the connecting spring is compressed, and the operator can pull the fixed cylinder up and down along the adjustment rod, thereby driving the pressure roller connected to the lower end of the fixed cylinder to rise and fall synchronously. After adjusting the gap between the pressure roller and the belt according to the thickness of the meat, the operator releases the pressure plate. The connecting spring rebounds and pushes the cross plate and insertion rod to reset. The insertion rod re-inserts into the corresponding groove to lock the fixed cylinder position, completing the rapid adjustment of the pressure roller height. After the motor is started, the motor output drives the first conveyor roller to rotate. The first conveyor roller drives the second conveyor roller to rotate synchronously through the belt to realize the continuous conveying of meat pieces. At the same time, the first conveyor roller drives the first drive wheel to rotate. The first drive wheel drives the first driven wheel to rotate through the chain. The first driven wheel drives the intermediate shaft to rotate. The second drive wheel on the intermediate shaft rotates accordingly and meshes with the second driven wheel. The second driven wheel drives the main shaft to rotate at high speed. The cutting blade and pressure ring mounted on the surface of the main shaft rotate synchronously at high speed. The meat piece to be cut is placed at the beginning of the belt. The pressure roller presses on the meat piece and applies a primary holding force to the meat piece while rotating with the belt to ensure that the position of the meat piece is stable and does not slip laterally during the conveying process. The meat piece is smoothly conveyed forward to the cutting mechanism position under the drive of the belt. Once the meat chunks are conveyed to the cutting area, the high-speed rotating cutting blades begin cutting them. When the meat chunks contact the pressure ring, multiple elastic strips inside the ring deform elastically according to the thickness of the meat chunks. The thicker the meat chunk, the flatter or even concave the elastic strips become, replacing their convex shape. For thinner meat chunks, the elastic strips remain relatively convex. This adaptive elastic adjustment allows the pressure ring to apply appropriate holding force to meat chunks of different thicknesses. The main shaft drives the gear ring to rotate, and the gear ring, through meshing with the elastic strips, provides driving force to the pressure ring, causing it to rotate synchronously. The staggered arrangement of the multiple elastic strips ensures that there is always an elastic strip engaged with the pressure ring. The outer side of the toothed ring maintains effective transmission. When encountering particularly thick pieces of meat, the gear will engage in the tooth groove to establish a rigid transmission connection. Simultaneously, the support spring inside the support ring below the belt undergoes elastic deformation under the weight of the meat and the pressure of the pressure ring. The support ring rotates with the belt and forms an upward elastic support force on the belt. It cooperates with the pressure ring above to form an upper and lower clamping structure, applying a balanced constraint force to the meat pieces during conveying and cutting. This effectively prevents the meat pieces, especially soft ones, from shifting and sliding due to uneven force during high-speed cutting, ensuring that the cutting blade can cut along the predetermined path to obtain a high-quality cutting effect.

[0015] (III) Beneficial Effects Compared with existing technologies, this invention provides a beef and mutton cutting device and its processing method, which has the following beneficial effects: This invention designs an adaptive cutting mechanism, realizing the adaptive processing of meat blocks of different thicknesses and hardness, solving the problem that traditional cutting equipment cannot flexibly cope with the diverse characteristics of raw materials. The core of this mechanism lies in the elastic linkage design between the pressure ring and the toothed ring through elastic strips. When the meat block passes through the cutting area, multiple elastic strips on the inner side of the pressure ring can adaptively undergo corresponding elastic deformation according to the actual thickness of the meat block. When the meat block is thick, the elastic strips are gradually flattened from their natural convex state or even become concave. When the meat block is thin, the elastic strips maintain a relatively convex natural state. This real-time response to meat block thickness... The elastic adjustment mechanism that varies in degree allows the pressure ring to apply appropriate and uniform holding force to meat pieces of different thicknesses. This avoids excessive compression of thick meat pieces, which can lead to meat deformation and juice loss, while also preventing thin meat pieces from shifting position during cutting due to insufficient holding force. More importantly, this adaptive holding function is particularly effective in processing softer meats. When the cutting blade cuts into the meat at high speed, the flexible holding force applied by the pressure ring through the elastic strip can effectively suppress the tendency of the soft meat pieces to elastically yield and laterally slip due to insufficient structural rigidity. This ensures that the soft meat pieces maintain a relatively stable spatial position and orientation angle throughout the entire cutting stroke, ensuring that the cutting blade can cut into the meat along the predetermined path.

[0016] Meanwhile, multiple support springs set between the support ring and the rotating ring form a lower support system that works in conjunction with the upper pressure ring. Under the elastic support of the support springs, the support ring can rotate with the belt while generating an upward elastic lifting force on the lower surface of the belt. This symmetrical clamping structure ensures that the meat pieces are subjected to balanced constraint forces from both the top and bottom directions during the conveying and cutting process, effectively eliminating the problem of unbalanced force on the meat pieces caused by unilateral clamping. In particular, it can improve the stability of the meat piece position and the consistency of the cutting size during high-speed cutting, and reduce the cutting scrap rate caused by meat piece deviation.

[0017] The downward conveying mechanism designed in this invention enables rapid adjustment and positioning of the pressure roller height, solving the problem that traditional fixed-height conveying systems cannot adapt to meat blocks of different thicknesses. This mechanism employs a sliding fit structure between the adjusting rod and the fixed cylinder, and locks the pressure roller height through the insertion fit of the slot and the insert rod. Before processing different batches of meat blocks, the operator only needs to press the upper and lower pressure plates to drive the upper and lower inclined rings to squeeze the abutment rod, causing the insert rod to disengage from the slot. Then, the fixed cylinder can be easily pulled up and down along the adjusting rod to adjust the gap between the pressure roller and the belt. After adjustment, releasing the pressing force causes the connecting spring to rebound and push the insert rod back into the corresponding slot, thus quickly locking the pressure roller height. The entire adjustment process is simple and intuitive, requiring no special tools. A single person can complete the height adjustment. Compared to traditional equipment that requires cumbersome operations such as disassembling bolts, replacing shims, or adjusting lead screws, this significantly improves work efficiency.

[0018] This invention improves the processing effect of soft meat by pre-adjusting the gap between the pressure roller and the belt in the downward conveying mechanism, so that the pressure roller applies a moderate initial holding force to the soft meat block, avoiding excessive deformation of the soft meat block during the conveying process. Subsequently, the pressure ring of the adaptive cutting mechanism flexibly clamps the soft meat block through the elastic strip, which not only provides sufficient restraint to prevent the soft meat block from slipping and deflecting during cutting, but also avoids the squeezing damage to the soft meat tissue caused by rigid holding. This allows the cutting blade to cut the soft meat block in a stable posture and with an intact tissue structure, solving the problems of rough cut surface, large size fluctuation and high scrap rate that are common in traditional equipment for processing soft meat.

The system also includes a downward conveying mechanism, which comprises two adjusting rods 31 located at opposite ends of the processing frame 11. Each adjusting rod 31 has multiple slots 32 on its surface. Preferably, a fixed cylinder 33 is slidably connected to the outer walls of the two adjusting rods 31. Multiple sliding holes 34 are provided on the surface of the fixed cylinder 33. A pressure roller 35 is positioned between the two adjusting rods 31, with both ends of the pressure roller 35 fixedly connected to the lower end face of the corresponding fixed cylinder 33. Multiple cross plates 36 are provided on the outer wall of the fixed cylinder 33. Inserted rods 37 are provided at the upper and lower ends of the side walls of the cross plates 36, and four abutment rods 38 are provided at the left and right ends of the side walls of the cross plates 36.

The upper inclined ring 312 is used in conjunction with the corresponding upper abutment rod 38, and the lower inclined ring 313 is used in conjunction with the corresponding lower abutment rod 38.

[0025] In this invention, before cutting a batch of meat pieces, the lower conveyor mechanism needs to be adjusted to adjust the distance between the pressure roller 35 and the belt 15 to match the thickness of the meat pieces. The operator manually presses the upper pressure plate 318 and the lower pressure plate 319, causing the upper pressure plate 318 to move downwards and the lower pressure plate 319 to move upwards. The downward movement of the upper pressure plate 318 drives the upper pressure rings 315 at both ends to move downwards. The upper pressure rings 315, through the short rod 314, drive the upper inclined ring 312 to move downwards synchronously. Simultaneously, the lower pressure plate 319 moves upwards, driving the lower pressure rings 317 at both ends to move upwards. The lower pressure rings 317, through the long rod 316, drive the lower inclined ring 313 to move upwards synchronously. Then, the upper inclined ring 312 and the lower inclined ring 313 respectively press the corresponding abutment rod 38, causing it to move outwards from the fixed cylinder 33. The abutment rod 38... The cross plate 36 drives the insertion rod 37 to slide along the limiting groove 311, thereby releasing the fixed state of the locking groove 32 on the surface of the adjusting rod 31. At this time, the connecting spring 39 is compressed, and then the two fixed cylinders 33 can be pulled up or down along the adjusting rod 31, thereby driving the pressure roller 35 connected below the fixed cylinder 33 to move up or down synchronously. After adjusting the distance between the pressure roller 35 and the belt 15, the operator releases the pressure on the lower pressure plate 319. The connecting spring 39 rebounds and pushes the cross plate 36 to reset, thereby driving the abutment rod 38 and the insertion rod 37 to reset. The upper inclined ring 312 and the lower inclined ring 313 are pressed and reset. The insertion rod 37 is inserted into the corresponding groove 32 again to fix the position of the fixed cylinder 33, thus completing the adjustment of the height of the pressure roller 35. The motor 12 is started, and its output drives the first conveyor roller 13 to rotate. The first conveyor roller 13 drives the second conveyor roller 14 to rotate synchronously via the belt 15. The first conveyor roller 13 drives the first drive wheel 16 to rotate, and the first drive wheel 16 drives the first driven wheel 18 to rotate synchronously via the chain 19. The first driven wheel 18 drives the intermediate shaft 17 to rotate, and the second drive wheel 110 at one end of the intermediate shaft 17 rotates synchronously. The second driven wheel 112, which meshes with the second drive wheel 110, rotates accordingly. The second driven wheel 112 then drives the main shaft 111 to rotate, and the main shaft 111 drives the cutting blade 25 and the pressure ring 21 on its surface to rotate at high speed. Then, the meat block to be cut is conveyed to the starting end of the belt 15. The pressure roller 35 presses on the top of the meat block to initially stabilize the conveying of the meat block. The pressure roller 35 rotates as the belt 15 conveys the meat block. When the meat block is conveyed to the cutting mechanism, the cutting blade 25 rotates at high speed to start cutting the meat block. After the meat block contacts the pressure ring 21, multiple pressure rings 21 are arranged inside. The elastic strip 24 deforms under pressure according to the thickness of the meat piece, and the pressure ring 21 moves relative to the toothed ring 22. Specifically, as the meat piece moves below the pressure ring 21, the elastic strip 24 gradually straightens from a convex shape and finally becomes concave. The thicker the meat piece, the deeper the concavity of the elastic strip 24. If the meat piece is thick enough, the gear 29 will engage with the tooth groove 23. The staggered design of multiple elastic strips 24 ensures that there is always an elastic strip 24 in contact with the outer wall of the toothed ring 22. The main shaft 111 drives... The toothed ring 22 rotates, and the meshing of the toothed ring 22 with the elastic strip 24 provides driving force to the pressure ring 21. Simultaneously, the support spring 28 in the support ring 27 below the belt 15 is also deformed under pressure. The support ring 27 rotates with the belt 15. While the upper and lower ends of the support ring 27 support and tension the belt 15, they also cooperate with the pressure ring 21 above to clamp the meat pieces during the conveying and cutting process, so as to prevent the meat pieces from shifting due to force during high-speed cutting and affecting the final cutting effect.

Each rotating ring (26) is coaxially provided with a support ring (27) on its outer side. A plurality of support springs (28) are provided between the support ring (27) and the rotating ring (26). The side wall of the support ring (27) abuts against the inner side wall of the belt (15).

5. A method for cutting and processing beef and mutton, using the beef and mutton cutting equipment described in claim 4, characterized in that: Includes the following steps: Before cutting a new batch of meat, the operator needs to pre-adjust the downward conveying mechanism according to the actual thickness of the meat. The operator presses the upper pressure plate (318) and the lower pressure plate (319) at the same time. The upper pressure plate (318) moves down and drives the upper inclined ring (312) to move down through the upper pressure ring (315) and the short rod (314). The lower pressure plate (319) moves up and drives the lower inclined ring (313) to move up through the lower pressure ring (317) and the long rod (316). The two inclined rings squeeze the corresponding abutment rod (38) to move it outward. The abutment rod (38) drives the insertion rod (37) along the limiting groove through the cross plate (36). (311) Slide away from the locking state of the groove (32) on the surface of the adjusting rod (31). At this time, the connecting spring (39) is compressed, and the operator can pull the fixed cylinder (33) up and down along the adjusting rod (31), thereby driving the pressure roller (35) connected to the lower end of the fixed cylinder (33) to rise and fall synchronously. After adjusting the gap between the pressure roller (35) and the belt (15) according to the thickness of the meat, release the pressure plate. The connecting spring (39) rebounds and pushes the cross plate (36) and the insert rod (37) to reset. The insert rod (37) is reinserted into the corresponding groove (32) to lock the position of the fixed cylinder (33), thus completing the rapid adjustment of the height of the pressure roller (35). After the motor (12) is started, the output end of the motor (12) drives the first conveying roller (13) to rotate. The first conveying roller (13) drives the second conveying roller (14) to rotate synchronously through the belt (15) to realize the continuous conveying of meat pieces. At the same time, the first conveying roller (13) drives the first drive wheel (16) to rotate. The first drive wheel (16) drives the first driven wheel (18) to rotate through the chain (19). The first driven wheel (18) drives the intermediate shaft (17) to rotate. The second drive wheel (110) on the intermediate shaft (17) rotates accordingly. It meshes with the second driven wheel (112), which drives the main shaft (111) to rotate at high speed. The cutting blade (25) and pressure ring (21) mounted on the surface of the main shaft (111) rotate at high speed synchronously. The meat block to be cut is placed at the starting end of the belt (15). The pressure roller (35) presses on the meat block and applies a primary holding force to the meat block while rotating with the belt (15), ensuring that the position of the meat block is stable and does not slip laterally during the conveying process. The meat block is smoothly conveyed forward to the cutting mechanism position under the drive of the belt (15). When the meat block is transported to the cutting area, the high-speed rotating cutting blade (25) begins to cut the meat block. After the meat block contacts the pressure ring (21), the multiple elastic strips (24) set on the inner side of the pressure ring (21) undergo elastic deformation according to the thickness of the meat block. The thicker the meat block, the more the elastic strips (24) are pressed flat or even concave. When the meat block is thinner, the elastic strips (24) remain relatively convex. This adaptive elastic adjustment allows the pressure ring (21) to apply appropriate holding force to meat blocks of different thicknesses. The main shaft (111) drives the toothed ring (22) to rotate. The toothed ring (22) provides driving force to the pressure ring (21) by meshing with the elastic strips (24). The synchronous rotation and the staggered arrangement of multiple elastic strips (24) ensure that there is always an elastic strip (24) in contact with the outer side of the toothed ring (22) to maintain effective transmission. When encountering particularly thick pieces of meat, the gear (29) will be inserted into the tooth groove (23) to establish a rigid transmission connection. Simultaneously, the support spring (28) in the support ring (27) below the belt (15) undergoes elastic deformation under the action of the weight of the meat and the pressure of the pressure ring (21). The support ring (27) rotates with the belt (15) and forms an upward elastic support force on the belt (15). It cooperates with the pressure ring (21) above to form an upper and lower clamping structure, ensuring that the cutting blade (25) can cut along the predetermined path to obtain a high-quality cutting effect.
