[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figure 1 、 Figure 4 As shown, a specific embodiment of the present invention discloses a chicken wing cutting device for chicken processing, including a conveying device 100 and a cutting device 200; a plurality of loading trays 300 are installed on the conveying device 100, and a clamping structure 320 for clamping the wing root and the wing mid-joint is provided on the loading tray 300, and the loading tray is driven to move in a circular motion and pass through the cutting device 200; the cutting device 200 includes a straightening mechanism 400 and a cutting mechanism 500, and the straightening mechanism 400 is used to straighten and straighten the chicken wings on the passing loading tray 300; the cutting mechanism 500 is used to cut the joint parts of the straightened chicken wings.

[0033] The above-mentioned chicken wing cutting equipment for chicken processing clamps and fixes the wing root and the joint in the wing through a clamping structure, determines a joint point, and can effectively prevent the chicken wing from shifting during subsequent transfer;

[0034] The splitting device includes a straightening mechanism and a cutting mechanism. The straightening mechanism is used to straighten and bend the chicken wings on the passing loading plate; the cutting mechanism is used to cut the joints of the straightened chicken wings; the wing roots and the joints in the wings are limited by the clamping structure, and then the chicken wings are straightened and bend by the straightening mechanism. The position of the entire chicken wing is relatively certain, and the positions of the two joints are naturally clearer. Especially for the processing of chicken wings of uniform specifications, even if the size of the chicken wings deviates, the joint points will be as close to the cutting position as possible, at least the joint points will not deviate due to the bending of the chicken wings. Cutting after the above-mentioned clamping and straightening actions can effectively improve the overall cutting accuracy and ensure the overall product quality.

[0035] Further, if Figure 2 、 Figure 3 As shown, the loading tray 300 includes a tray body 310, which includes a rectangular support plate 311, and support bars 312 are fixed to the top surfaces of the two long sides of the support plate 311; a clamping structure 320 is installed on the support bar 312 near the downstream side of the conveying, and the clamping structure is retractable and movable along the conveying direction, and a narrowed clamping portion is formed between the head of the clamping structure and the support bar on the other side; a portion for accommodating chicken wings is formed by two support bars, and the support bar near the downstream side is used as the installation portion of the clamping structure; the clamping structure is arranged in this direction, on the one hand, to form a clamping portion, which is convenient for putting in and clamping the chicken wings; on the other hand, it provides conditions for the operation of the subsequent straightening mechanism, prevents interference with the straightening mechanism, and ensures that the straightening mechanism can use the support bar on the upstream side as the force-bearing portion for supporting the chicken wings, so as to straighten and bend the chicken wings;

[0036] Among them, it should be pointed out that the conveying device is a chain plate conveyor belt structure, in which multiple chain plates are mounted on two oppositely arranged chains, and docking plates are fixed at both ends of the support plate. The docking plates are installed on the chain plates by bolts, so that the loading tray moves with the conveying chain; the chain plate conveyor belt is a common conveying structure that can be purchased and used on the market, and the specific details are not described here.

[0037] The first locking cam 710 of the embodiment of the present invention is a kind of locking cam 711, and the locking cam 712 is a kind of locking cam 711 of the embodiment of the present invention. The back compression facilitates the placement of the chicken wings, and it can also rebound quickly after the force is released, providing a more stable clamping effect on the joints of the chicken wings; and this action does not require electric drive, the overall structure is simple, and it is convenient for the design and layout of other structures; further, the top view plane of the clamping head 712 is a right-angled triangle structure, and the right-angled side planes of the two clamping heads are arranged opposite to each other, and there is a spacing between the two for the cutting knife to move; an isosceles triangle outline is formed between the two clamping heads, which is suitable for the joints between the root of the wing and the middle of the wing; this structural design is on the one hand to adapt to the corner shape of the joint between the root of the wing and the middle of the wing, to achieve better clamping and adhesion effects, and to prevent the chicken wings from shifting during the transfer process; on the other hand, it can provide space for the cutting knife to move, and simultaneously meet the cutting action of the cutting knife on this joint without affecting the clamping effect.

[0038] Furthermore, if Figures 4 to 6 As shown, the cutting mechanism 500 includes a motor 510, a transmission shaft 520, and a cutting knife 530; the transmission shaft 520 is mounted on the support frame 210 through a bearing rotation mount, and the output shaft of the motor 510 is transmission-connected to one end of the transmission shaft 520; the number of cutting knives is 2, and the cutting knife 530 is fixedly mounted on the transmission shaft 520, corresponding to the joint parts of the straightened chicken wings; a first slot 314 for the cutting knife 530 to move is correspondingly provided on the support bar 312; the cutting mechanism is simple, and the two cutting knives are rotated by the motor to effectively cut the joint parts of the chicken wings; the straightening mechanism 400 is located on the side of the cutting mechanism 500 close to the upstream, so that the chicken wings are cut in a straightened state, achieving an accurate cutting effect.

[0039] Furthermore, if Figure 3 As shown, a groove 315 is provided on the bottom surface of the support plate 311 corresponding to the first slot 314, and both ends of the groove extend to both sides of the support plate. The bottom end of the cutting knife is lower than the top surface of the support plate, ensuring that the chicken wings can be completely cut and divided when the cutting knife passes.

[0040] Furthermore, if Figure 6 、 Figure 7As shown, the straightening mechanism 400 includes a support shaft 410, a limiting shaft 420, a first bracket 430, a plurality of hooks 440 and a plurality of tension springs 450; the support shaft 410, the limiting shaft 420 and the first bracket 430 are all fixedly mounted on the support frame 210, the first bracket 430 is located below the support shaft 410, and the limiting shaft 420 is located below the side of the support shaft 410 close to the downstream of the conveyor; the hook 440 is a plate-like structure, including a slat portion 441, one end of the slat portion 441 is fixedly provided with a ring portion 442, and the other end is bent to form a hook portion 443; the middle part of the slat portion 441 is provided with an extension portion 444, and the extension portion 4 44 is provided with a second guide hole 445 running through both sides; the collar portion 442 is sleeved on the support shaft 410, and the pull hook rotates around the support shaft through the collar; the second guide hole 445 extends along the rotation trajectory of the pull hook 440, and the limit shaft 420 is passed through the second guide hole 445. When the upper end of the second guide hole abuts against the limit shaft, the curved hook portion is in an upright position, and the bottom end is not lower than the top surface of the support plate; one end of the tension spring 450 is connected to the first bracket 430, and the other end is connected to the lower side bar position of the slat portion 441, providing elastic force for pulling down the pull hook; the support bar 312 is provided with a second slot 316 for the pull hook 440 to pass through;

[0041] This structural design allows the hook to be mainly supported by the support shaft and serve as a rotating fulcrum. The limit shaft and the second guide hole cooperate to make the hook rotate and swing along the required direction so that it can accurately fall into the position of the second slot. When the loading tray moves through the straightening mechanism, the hook can smoothly enter the interior of the loading tray and provide a pressing, correcting and straightening effect on the chicken wings. In addition, the hook provides a reset tension through the tension spring. When the loading tray below passes, the bent hook contacts the chicken wings and provides a force to prevent the chicken wings from moving. And continue the entire movement process, thereby achieving the action of straightening and correcting the chicken wings; when the loading plate continues to move forward, the contact force between the chicken wings and the pull hook continues to increase until it can overcome the elastic force of the tension spring, and the pull hook is pushed up, until the chicken wings are out of the position of the pull hook, the pull hook will be reset to the initial position under the tension of the tension spring, preparing for the passage of the next loading plate; it should be pointed out that in the process of the pull hook blocking and pressing the chicken wings, and the chicken wings pushing up the pull hook, the cutting knife completes the cutting of the chicken wings, achieving the effect of cutting the chicken wings after pressing and straightening them;

[0042] Furthermore, the hooks are distributed in three groups corresponding to the wing root, wing middle and wing tip, and the cutting knives are set in the corresponding intervals of the hook groups to ensure that the cutting knives and the hooks do not affect each other, and the cutting action is performed only after the compression and straightening;

[0043] Furthermore, since the width of the wing tip is much smaller than that of the wing middle and wing root, the length of the pull hook corresponding to the wing tip is shorter, so that the pull hook can contact the chicken wing as synchronously as possible, thereby providing an effective compression and straightening effect;

[0044] It should be pointed out that in large-scale production, chicken wings are processed according to uniform specifications, the size of the chicken wings is relatively consistent, and the error range is acceptable;

[0045] Furthermore, both ends of the support shaft are fixedly installed with shaft brackets through column pins, and the shaft brackets are fixedly installed on the support frame by bolts, and the support shaft itself will not rotate; the support shaft is provided with annular grooves on both sides corresponding to each pull hook for clamping the second retaining spring, and the limiting collar is rotatably installed on the support shaft without deviation; and one end of the limit shaft is fixedly provided with a docking piece, which is fixed to the support frame on one side by bolts, and the support frame on the other side is provided with an insertion hole corresponding to the limit shaft, and the end of the limit shaft is inserted into the insertion hole, so that the limit shaft is fixedly installed on the support frame and will not easily loosen. The limit shaft adopts this structure to easily pass through the second guide hole, which is convenient for overall installation;

[0046] Furthermore, both ends of the first bracket are mounted on the support frame by bolts, and the first bracket is provided with a plurality of convex plates corresponding to the plurality of pull hooks, and a first through-hole is provided on the convex plate, and a second through-hole is provided corresponding to the position of the lower side strip of the slat portion, and the two ends of the tension spring are respectively hooked at the first through-hole and the second through-hole, and each pull hook is applied with force by an independent tension spring, which better adapts to the force requirements of different parts of the chicken wing and provides a better clamping effect;

[0047] Furthermore, the edges of the first slot and the second slot are chamfered to facilitate the passage of the cutting knife and the hook;

[0048] Furthermore, a first gantry is installed on the frame of the conveying device. The first gantry is located in the middle of the conveying device and spans the conveying device. Two support frames are symmetrically installed on the bottom surface of the frame plate of the first gantry. The motor is also installed on the bottom surface of the frame plate, so that the entire cutting mechanism and straightening mechanism are built on the first gantry, providing stable operating conditions.

[0049] Furthermore, the bottom end of the hook portion 443 is an arc-shaped structure, and the bottom end of the hook portion 443 is flush with the top surface of the support plate 311. The arc portion of the hook portion can make better contact with the chicken wings, especially facilitating the pull hook to be lifted up, ensuring that the pull hook can be smoothly swung upward when it is subjected to sufficient force, so that the loading tray can pass smoothly.

[0050] Furthermore, a baffle 317 is fixedly provided on the top of the inner wall of the support bar 312 located on the upstream side, and the baffle is provided with notches corresponding to the first slot and the second slot, which does not affect the movement of the cutting knife and the hook; the design of the baffle further strengthens the blocking of the chicken wings, preventing the chicken wings from easily curling up or detaching when subjected to the squeezing force of the hook, and maintaining an effective clamping effect for cutting.

[0051] Furthermore, two dividing plates 600 are installed at the unloading end of the conveying device 100, and the two dividing plates 600 are respectively arranged corresponding to the two cutting knives 530. The dividing plates extend in an arc shape along the unloading end of the conveying device, and the dividing plates 600 are stuck in the corresponding first slots 314; further, a second gantry is installed at the output end of the conveying device, and a second bracket is installed at the bottom. The top of the dividing plate is installed on the second gantry by bolts, and the bottom end is installed on the second bracket by bolts, so that the dividing plate is firmly installed and maintained in the required position; when the loading tray passes through the dividing plate, the wing roots, wing middles, and wing tips that have been cut inside fall to the corresponding areas, achieving the effect of separation.

[0052] The present invention is described through preferred embodiments. Those skilled in the art will appreciate that various modifications or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
