Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of poultry paw processing, and particularly relates to an automatic bone-picking device and method for poultry paw processing. BACKGROUND

[0002] Poultry paws are very popular in many Asian countries as a delicacy. Poultry paw processing mainly refers to the process of treating and making poultry feet such as chicken claws and duck paws. The processing process usually includes cleaning, removing impurities, deboning, cooking (which can be boiling, stewing, frying, etc.), and adding seasonings for marinating or mixing according to different taste requirements.

[0003] In the prior art, poultry paw deboning is mostly done manually, that is, the operator debones the poultry paws to be processed by manual means. Although the prior art also has some processing equipment for poultry paw deboning, such equipment does not require the operator to hold a knife for cutting, but still requires the operator to hold the chicken claws to operate the chicken claws according to the processing procedure. This processing method has certain efficiency improvement compared to the fully manual operation method, but the switching between different procedures still relies on manual operation, and the work efficiency still has great room for improvement.

[0018] Another purpose of the embodiment of the application is an automatic bone picking method for poultry leg processing, based on the automatic bone picking device for poultry leg processing, including the following steps:

[0019] Step 1: Place the washed poultry leg on the conveying belt, then start the driving motor, drive the conveying roller to rotate, and drive the conveying belt to convey the poultry leg.

[0020] Step 2: When the poultry foot is conveyed to the bottom of the positioning seat, the lifting unit drives the cutting module to move downwards as a whole. The contouring groove first fixes the poultry foot and separates the toes. When the bottom surface of the positioning seat contacts the conveyor belt, the connecting unit releases the limit on the positioning seat. At this time, the lifting unit drives the cutting seat to move downwards on its own, so that the contouring cutter passes through the cutter hole and inserts into the positioning seat, making a cut on the poultry foot through the contouring cutter. After the cut is completed, the lifting unit drives the cutting seat to move upwards to the initial state.

[0021] Step 3: After the incision is completed, the poultry feet are conveyed to the deboning module via a conveyor belt. At this time, the upper rubbing plate will be at its upper limit position, and the poultry feet will fall between the upper and lower rubbing plates. Then, the pressing unit will drive the upper rubbing plate to move downward, so that the poultry feet are pressed by the upper and lower rubbing plates. At the same time, the reciprocating unit drives the upper and lower rubbing plates to reciprocate, and the pressure ridges on the upper and lower rubbing plates will quickly squeeze and rub the poultry feet to achieve deboning. After deboning, the poultry feet will slide off the lower rubbing plate under the action of gravity and can then be collected.

[0022] This invention provides an automatic deboning device and method for processing poultry feet. In use, simply place the cleaned poultry feet on a conveyor belt, then start the drive motor. The drive motor rotates the conveyor rollers, thereby transporting the poultry feet along the conveyor belt. When the poultry feet reach below the positioning seat, the connecting unit fixes the positioning seat in the cutting seat. The lifting unit moves the entire cutting module downwards, and the contouring groove first fixes the poultry feet, separating the toes. When the bottom surface of the positioning seat contacts the conveyor belt, the connecting unit releases the limiting position on the positioning seat. At this point, the lifting unit moves the cutting seat downwards independently, allowing the contouring cutter to pass through the cutter hole and insert into the positioning seat, thus making a cut in the poultry feet. After the cut is completed, the lifting unit moves the cutting seat upwards. The cutting seat initially moves upwards independently until the elastic restoring force of the first spring is released. Then, the cutting seat moves upwards synchronously with the positioning seat via the first spring. During this process, the connecting unit fixes the positioning seat back into the cutting seat, allowing the cutting module to return to its initial state. The poultry feet are individually incised by the reciprocating lifting and lowering of the lifting unit. After incision, the poultry feet are conveyed to the deboning module via a conveyor belt. At this point, the upper rubbing plate is at its upper limit position, allowing the poultry feet to fall between the upper and lower rubbing plates. Then, the pressing unit drives the upper rubbing plate downwards, pressing the poultry feet down between the upper and lower rubbing plates. Simultaneously, the reciprocating unit drives the upper and lower rubbing plates to reciprocate, using the pressure ridges on the upper and lower rubbing plates to quickly squeeze and knead the poultry feet, thus deboning them. After deboning, the poultry feet slide off the lower rubbing plate under gravity and can be collected. This device enables automated deboning of poultry feet, is simple to operate, highly efficient, and effective. BRIEF DESCRIPTION OF DRAWINGS

The inside of the cutting seat 21 is also provided with a contour cutter 25, and the top wall of the positioning seat 22 is provided with a cutter hole 24 that matches the contour cutter 25.

[0039] The deboning module 5 is provided with two groups, and the two groups of the deboning module 5 are respectively arranged at the ends of the two conveying belts 12 (the end of the conveying belt 12 is defined as the discharging end), the deboning module 5 comprises a lower plate 52 which is slidingly installed on the rack 8 along the conveying direction of the conveying belt 12, and further comprises a limiting column 55 which is installed on the rack 8, an upper plate 51 is arranged above the lower plate 52, the bottom surface of the upper plate 51 is inclined, and a plurality of pressing edges 53 are equidistantly distributed on the bottom surface of the upper plate 51, the upper surface of the lower plate 52 is also inclined, the bottom surface of the upper plate 51 and the upper surface of the lower plate 52 are parallel to each other, and a plurality of pressing edges 53 are equidistantly distributed on the upper surface of the lower plate 52, a sliding seat 54 is slidingly installed on the limiting column 55 in the vertical direction, a third spring 56 connected with the sliding seat 54 is arranged in the limiting column 55, one side of the lower plate 52 is slidingly installed in the sliding seat 54 in the horizontal direction, a reciprocating unit 6 for driving the upper plate 51 and the lower plate 52 to simultaneously move towards or reversely in the horizontal direction is further arranged on the rack 8, and a pressing unit 7 is further connected to the conveying roller 11 near the end of the conveying belt 12, the pressing unit 7 drives the upper plate 51 to reciprocate in the vertical direction by converting the rotary motion of the conveying roller 11 into linear reciprocating motion in the vertical direction.

[0040] In the embodiment of the present application, when in use, only need to place the cleaned poultry feet on the conveying belt 12, and then start the driving motor 13 to drive the conveying roller 11 to rotate, thereby driving the conveying belt 12 to convey the poultry feet. When the poultry feet are conveyed to the position below the positioning seat 22, the connecting unit 4 will fix the positioning seat 22 in the cutting seat 21, and the lifting unit 3 will drive the cutting module 2 to move downward as a whole, the profiling groove 23 will first fix the poultry feet and separate the toes of the poultry feet, and when the bottom surface of the positioning seat 22 contacts with the conveying belt 12, the connecting unit 4 will release the positioning of the positioning seat 22, at this time, the lifting unit 3 will drive the cutting seat 21 to move downward alone, thereby making the profiling cutter 25 pass through the cutter hole 24 and insert into the positioning seat 22, and the poultry feet can be cut by the profiling cutter 25. When the cutting is completed, the lifting unit 3 drives the cutting seat 21 to move upward, the cutting seat 21 first moves upward alone until the elastic restoring force of the first spring 27 is released, and then the cutting seat 21 drives the positioning seat 22 to move upward synchronously through the first spring 27, in this process, the connecting unit 4 will fix the positioning seat 22 in the cutting seat 21 again, thereby making the cutting module 2 return to the initial state. The poultry feet can be cut one by one through the reciprocating lifting of the lifting unit 3. The poultry feet after cutting are conveyed to the bone-removing module 5 through the conveying belt 12, at this time, the upper pressing plate 51 is at the upper limit position, which is convenient for the poultry feet to fall between the upper pressing plate 51 and the lower pressing plate 52. Then the pressing unit 7 drives the upper pressing plate 51 to move downward, so that the poultry feet are pressed by the upper pressing plate 51 and the lower pressing plate 52. At the same time, the upper pressing plate 51 and the lower pressing plate 52 are driven by the reciprocating unit 6 to reciprocate, and the poultry feet are quickly extruded and rubbed by the pressing edges 53 on the upper pressing plate 51 and the lower pressing plate 52, thereby realizing the bone-removing of the poultry feet. The poultry feet after bone-removing will slide off the lower pressing plate 52 under the action of gravity, and can be collected.

[0041] As shown in Figure 1 As a preferred embodiment of the present application, the output end of the driving motor 13 is connected with any one of the conveying rollers 11 through a belt and pulley mechanism, thereby realizing the conveying of the poultry feet through the conveying belt 12. In addition, the rotation of the conveying roller 11 can be controlled by controlling the start and stop of the driving motor 13, and the sequential conveying of the poultry feet can also be realized.

The large opening at the lower end can facilitate the poultry paw to enter the profiling groove 23. During the process that the positioning seat 22 continuously moves downward until the poultry paw is covered, the profiling groove 23 continuously shrinks in size, which can separate and fix each toe of the poultry paw, and facilitate the cutting.

[0045] As shown in Figure 4 and Figure 5 , as a preferred embodiment of the present application, the profiling cutter 25 is a hollow structure, and a plurality of gas outlets 251 are formed on the profiling cutter 25. The top of the cutting seat 21 is further provided with a gas inlet connector 26 which is in communication with the interior of the profiling cutter 25. The gas inlet connector 26 is used to connect an external gas supply device.

[0046] In the embodiment of the present application, when in use, the gas inlet connector 26 can be connected with an external gas supply device such as a gas pump. The external gas supply device can deliver gas into the profiling cutter 25 through the gas inlet connector 26, and blow the gas flow to the outside of the profiling cutter 25 through the gas outlets 251.

At this time, the cutting seat 21 and the positioning seat 22 can slide relative to each other, and the cutting seat 21 will move downward alone and compress the first spring 27, so as to push the profiling cutter 25 to pass through the cutter hole 24 and cut the notch in the profiling groove 23.

[0049] When the cutting is completed, the lifting unit 3 drives the cutting seat 21 to move upward, the cutting seat 21 first moves upward alone until the elastic recovery force of the first spring 27 is released (at this time, the cross rod 42 is aligned with the positioning hole), then the cutting seat 21 can drive the positioning seat 22 to move upward synchronously through the first spring 27, in this process, the elastic recovery force of the second spring 43 will gradually push the cross rod 42 to be inserted into the positioning hole and push a part of the vertical rod 41 out of the bottom of the positioning seat 22, so as to make the cutting module 2 return to the initial state.

The reciprocating lifting of the lifting unit 3 can cut the poultry claws one by one. After the cutting is completed, the poultry claws are conveyed to the bone removal module 5 through the conveying belt 12, at this time, the sliding column 74 is located in the outer convex segment of the cam groove 72, the upper plate 51 is located at the upper limit position, and the lower plate 52 is located at the side close to the end of the conveying belt 12, so that the poultry claws can fall between the upper plate 51 and the lower plate 52. With the rotation of the conveying roller 11 and the cam 71, the sliding column 74 slides from the outer convex segment to the circular segment, so that the mounting rod 75 is driven downward by the connecting rod 73, and the pressing rod 77 is driven downward synchronously, so that the poultry claws are pressed by the upper plate 51 and the lower plate 52.

[0059] At the same time, the second electric telescopic rod 64 can drive the two lower racks 63 to move linearly along the conveying direction of the conveying belt 12 at the same time through the second connecting plate 65, the lower racks 63 can drive the transmission gear 62 to rotate at the same time, and then the upper racks 63 are driven to move linearly synchronously through the transmission gear 62, and the movement directions of the upper and lower racks 63 are always opposite, that is, the upper plate 51 and the lower plate 52 are driven to move towards each other or in opposite directions at the same time. The pressing edges 53 on the upper plate 51 and the lower plate 52 are used for quickly extruding and rubbing the poultry claws, so that the poultry claws are deboned. The deboned poultry claws slide off the lower plate 52 under the action of gravity, and can be collected.
