Description

Technical Field

[0001] This utility model relates to a V-shaped bone cutting component for poultry. Background Technology

[0002] Currently, various individual machines in automated poultry breast deboning lines cannot effectively separate large and small breast meat from the breastplate without removing the V-shaped bone. In poultry breast processing, traditional deboning processes often leave behind V-shaped bone residue (such as small bone spurs and other small bone fragments), posing food safety hazards (choking, cuts), reducing ease of consumption, increasing the cost and complexity of industrial processing, and decreasing the utilization rate of net meat. This invention is proposed to solve these problems.

[0003] An investigation revealed that the utility model patent for deboning poultry breasts and removing V-shaped bones, patent number CN 221468902 U, although it discloses a utility model, has a high system complexity: 12 sets of mechanical linkage components (cams / connecting rods / rollers), a single unit failure can cause the entire line to shut down, and the mean time between failures (MTBF) is only 120 hours; the meat loss rate fluctuates greatly: when the pressure of the peeling rollers is uneven, the local meat loss rate can reach 15% (the patent average is 5%). Utility Model Content

During the second half of the stroke, the machine control valve contacts the stroke contact block, thereby driving the telescopic part to extend and push the main blade and the left and right blades to move downward and insert into the chicken breast. Finally, the blades of the three blades of the main blade and the left and right blades contact each other, causing the V-shaped bone to separate from the chicken breast body. When the adjustment roller is in the rising section AE, the machine control valve always remains in contact with the stroke contact block, the state of the drive telescopic part remains unchanged, and the main blade part and the left and right blade parts are always in the closed state. During the upward phase AE, adjust the roller to rise, which will cause the knife holder to rise, and cause the V-shaped bone in the closed space of the three knives to be picked out from the chicken breast upwards. When the adjustment roller is in the horizontal section EF, the mechanical control valve disengages from the stroke contact block, drives the telescopic part to retract, the three knives rise and open, and the V-shaped bone falls off; at the same time, the control valve corresponding to the air block contacts the corresponding limit plate, the air block conducts exhaust, ensuring that the V-shaped bone can fall off and preventing it from sticking to the air block. During the horizontal segment EF, the control valve of the air blowing block... When the adjusting roller is in the idle stroke section FT, the mechanical control valve corresponding to the telescopic part is driven to idle.

[0008] At the lowest point of the stroke, the blades of the main blade and the side blades on both sides face the blade holder. The blade on the side is serrated.

[0009] The main blade has a V-shaped cutting edge, and the two sides of the V-shaped cutting edge are set parallel to the stroke of the corresponding side blade. The blades on both sides of the side blade section.

[0024] The center corner block 27 is located on the back side of the main blade section 21 and at the lower part of the stroke on the tool holder body 11.

[0025] An air-blowing block 29 is provided on the tool holder body 11; An organic control valve 6, a stroke contact block 7, and a blow-up contact block are provided between the support frame 1 and the guide rotating part 5; The groove section 9 includes a horizontal section TA, rising sections A-E, a horizontal section EF, and an idle section FT connected in sequence. When adjusting roller 16 in the horizontal section TA, the mechanical control valve 6 is used to contact the stroke contact block 7; When the roller 16 is adjusted to the horizontal section TA, the state of the drive extension part 17 remains unchanged during the first half of the stroke. During the second half of the stroke, the machine control valve 6 contacts the stroke contact block 7, thereby driving the extension part 17 to extend and push the main blade 21 and the left and right blades 24 to move downward and insert into the chicken breast. Finally, the blades of the three blades of the main blade 21 and the left and right blades 24 contact each other, causing the V-shaped bone to separate from the chicken breast body. When the roller 16 is in the rising section AE, the machine control valve 6 always remains in contact with the stroke contact block 7, the state of the drive extension part 17 remains unchanged, and the main blade part 21 and the left and right blade parts 24 are always in the closed state. During the upward phase AE, the roller 16 is adjusted to rise, which drives the knife holder 11 to rise, causing the V-shaped bone in the closed space of the three knives to be picked out from the chicken breast upwards. When the roller 16 is adjusted to the horizontal section EF, the mechanical control valve 6 disengages from the stroke contact block 7, drives the telescopic part 17 to retract, the three knives rise and open, and the V-shaped bone falls off; at the same time, the control valve corresponding to the air blowing block 29 contacts the corresponding limit plate, and the air blowing block 29 conducts exhaust to ensure that the V-shaped bone can fall off and prevent it from sticking to the air blowing block 29. During the horizontal segment EF, the control valve of the air blowing block 29... When the adjustment roller 16 is in the idle section FT, the mechanical control valve 6 corresponding to the telescopic part 17 is driven to idle.

[0026] At the lowest position of the stroke, the blades of the main blade 21 and the side blades 24 on both sides face the blade holder body 11; The 24 blades on the side blade are serrated.

[0027] The main blade 21 has a V-shaped blade, and the two sides of the V-shaped blade are arranged parallel to the stroke of the corresponding side blade 24. The blades of the side blades 24 on both sides.

[0028] The inclined bracket 14 is connected to the tool holder body 11 through the inclined adjustment groove 13 on the inclined adjustment bracket 12.

[0029] Side auxiliary wheels 25 are provided on both sides of the tool holder body 11 for rolling contact with the inclined slider 23 that moves downwards at an angle.

[0030] An elastic pressure plate 28 is provided at the bottom of the tool holder body 11.

[0031] A guide rail 2 is provided on the support frame 1 for use with a transport trolley; the trolley is equipped with a claw 3.

[0032] The original working principle employed a progressive bone-meat separation method: it involved a three-stage cutting process to sever the connecting tissue between bone and meat layer by layer; then, a mechanical roller peeling technique utilized the elastic difference between meat and bone for physical separation, and air blowing removed any remaining bone fragments. Before the improvement, the process involved: pre-cutting: a curved blade made a 1.5mm deep guide mark (anti-slip blade); precision cutting: a conical blade cut 3mm deep along the V-shaped bone contour (to separate the ribs); deep cutting: a U-shaped blade vertically cut into the cartilage groove, severing the distal tendons. Roller peeling (1.2-2.7 seconds): this process was complex, lacked versatility, was inefficient, had a long stroke, and was prone to trapping meat.

[0033] The improved V-shaped bone contour cutting mechanical bone removal mechanism includes: a pneumatic three-jaw gripper; cutting action; and pneumatic closure of the three-jaw cutter when it reaches the designated position, causing the V-shaped bone to be removed.

[0034] Bone removal action: The three claws wrap around the V-shaped bone; lift it vertically upward at a constant speed; after the bone and meat are separated, it reaches the designated position as the drum rotates and is thrown into the receiving trough.

[0035] The telescopic part is driven by a cylinder, which provides the power source to drive the slider mechanism to move up and down. The inclined support serves as the upper slider seat, sliding along the overall drum track; The telescopic slider section adopts a single-stage transmission to connect to the intermediate blade and control its cutting action. The inclined slider uses a two-stage transmission system (two or three stages) to connect to the side blade and control its cutting action. The main blade uses a central blade for longitudinal cutting, which closes when cutting together with the side blades, completely separating the V-shaped bone from the sternum. The side blade is used for longitudinal cutting. It closes when cutting together with the middle blade, so that the V-shaped bone is completely separated from the sternum. The elastic pressure plate, using a breast meat pressure plate, secures the poultry breast meat and prevents it from shifting during processing; In the previous process, the operator hangs the chest cover on the transport trolley clamp. The trolley moves along a fixed track to secure the chest cover to the transport trolley clamp. Then, the peeling machine completely removes the skin from the chest cover. After changing direction, it enters the drum assembly to remove the V-shaped bone.

[0036] When the trolley runs on the straight track to the guide drive unit that is tangent to the straight track, there is a positioning slot on the annular push plate of the guide drive unit. The trolley is pushed by the slot and rotates around the drum. After rotating half a circle, it runs along the straight track that is tangent to the drum.

[0037] Each V-shaped bone removal device is mounted on the guide drive unit via two lifting guide rods, i.e., vertical guide shafts, which correspond one-to-one with the positioning slots on the annular push plate. Thus, each transport trolley corresponds one-to-one with the V-shaped bone removal device. The V-shaped bone removal device has roller bearings on its back, which can run on the outer circular track of the drum. When the drum is stationary, the shape of the track allows the V-shaped bone removal device to move up and down as it rotates around it. During the rotation, push rods push forward to fix the two beak-like protrusions of the breast cap. In this way, the position of the V-shaped bone of each breast cap product relative to the V-shaped bone removal device is fixed and uniform. The breast cap pressure plate presses down on the breast cap to fix the breast meat and prevents displacement when cutting the V-shaped bone.

[0038] After rotating to the designated position, the structure triggers the control valve, and the cylinder extends the middle blade and the two side blades to cut to the fixed position at the same time. At this time, the three blades form a closed state with the front open. The three blades contain V-shaped bone and a small amount of large breast meat. At this time, the large breast pre-cutting scraper reaches the pre-cutting incision position.

[0039] Rotate to the next position, the V-shaped bone removal device rises evenly along the drum track, the three blades remain in the closed state, the large breast pre-cutting scraper pre-cuts the large breast meat downwards, the forces of the upper and lower movements interact to prevent the breast cap from falling off the transport trolley clamp.

[0040] Finally, the conveyor trolley clamps exiting the drum enter the synchronous belt track and separate tangentially from the V-shaped bone removal equipment. This facilitates the separation of the V-shaped bone from the chest cover. Upon reaching the V-shaped bone receiving port, the pneumatic valve closes, the cylinder retracts, and the three blades open simultaneously, causing the V-shaped bone to naturally detach into the receiving port. The angle, height, left and right positions of the clamp between the V-shaped bone removal device and the transport trolley are all adjustable. The three-claw blade forms an almost seamless, sealed state, completely encasing the V-shaped bone inside, ensuring the integrity of the V-shaped bone and leaving no bone fragments.

[0041] The angle, height, left and right position of the V-shaped bone removal equipment and the transport trolley clamps are adjustable, making it suitable for deboning the breastplates of most poultry.
