Description

Technical Field

[0001] This utility model relates to a fixing mold for deboning poultry claws, belonging to the field of food processing technology. Background Technology

[0002] Chicken feet, duck feet, and other poultry feet, with their diverse flavors, are increasingly popular, and deboned poultry feet are especially favored because they are boneless. Existing deboning molds for poultry feet have a cavity shaped like a poultry foot, which is then used to fix the poultry feet for deboning. However, poultry feet vary greatly, and even within the same type of poultry, feet can differ in size and thickness. Existing molds cannot adequately accommodate these differences. If the base of the toe is used as a positioning reference, the thickness of each foot and toe varies, making it easy to break bones during deboning. This requires subsequent manual removal of bone fragments and affects the integrity and aesthetics of the deboned poultry feet. Utility Model Content

[0003] The purpose of this invention is to solve the problem of inaccurate fixation and positioning caused by the differences in poultry claws, and to provide a fixation mold for deboning poultry claws that can adapt to poultry claws of different sizes.

[0023] The present invention will be further described in detail below with reference to specific embodiments.

[0024] like Figure 1-4As shown, a fixed mold for deboning poultry claws includes a base mold 1, and a lower toe mold 11 for accommodating and positioning the poultry claw. The lower toe mold 11 is elastically connected to the base mold 1. When the poultry claw fixed on the base mold 1 is compressed, the lower toe mold 11 can adapt to the changes in the size of the poultry claw's toes, thereby ensuring the stability of the toe bone positioning after the poultry claw is compressed. Although poultry claws and toes vary in size and thickness, the meat in the toe is generally located at the base of the toe, not on the back. Using the position where the poultry claw is compressed as the positioning reference is more conducive to the precise positioning of the deboning knife, avoiding the phenomenon of removing too much meat from the poultry claw and breaking the toe bone due to inaccurate positioning.

[0025] In one embodiment of the elastic lifting of the lower toe mold 11, an elastic element 12 is provided between the bottom mold 1 and the lower toe mold 11. Preferably, the elastic element 12 is provided at both the front and rear ends of the lower toe mold 11, or the elastic element 12 acts on at least the front and rear ends of the bottom of the lower toe mold 11, so that the lower toe mold 11 lifts and lowers smoothly without uneven height.

[0026] In a preferred embodiment of this invention, the bottom mold 1 has a claw mold cavity 10 that matches the bird's claw, and the lower toe mold 11 is accommodated in the claw mold cavity 10. An elastic element 12 is disposed between the lower toe mold 11 and the claw mold cavity 10. The lower toe mold 11 elastically rises and falls within the claw mold cavity 10 without the need to connect or guide the elastic element 12. More preferably, the bottom mold 1 has two symmetrical thumb cavities 13 to increase the versatility of the mold, eliminating the need to distinguish between the left and right claws.

[0027] In a preferred embodiment of this utility model, there are three lower toe molds 11, and each lower toe mold 11 is provided with an elastic member 12 at least pressing against the front and rear ends of the lower toe mold 11 to ensure that the lower toe mold 11 can rise and fall smoothly.

[0028] The fixing mold of this utility model may further include an upper mold 2, which is provided with an upper toe mold 21 that can dock with the lower toe mold 11 to fix the bird's claw. There may be three upper toe molds 21, or one upper toe mold 21 may have three matching toe mold cavities.

[0029] The upper mold 2, which is molded together with the bottom mold 1 to fix the poultry claw, can be set at a corresponding position in each process. When the bottom mold 1 carries the poultry claw to each process, it closes with the upper mold 2 at that station. Of course, the upper mold 2 can also be set on the bottom mold 1, and the upper mold 2 can be raised and lowered on the bottom mold 1 to close or separate. The lower toe mold 11 is elastically connected to the bottom mold 1, which helps to maintain the consistency of the position of the upper mold 2 when it closes.

[0030] In one specific embodiment of this utility model, the upper toe mold 21 has an upper toe mold cavity 211, and the lower toe mold 11 has a lower toe mold cavity 111. When the upper toe mold cavity 211 and the lower toe mold cavity 111 are closed, they form a mold cavity surrounding the bird's claw and toes. The side wall of the lower toe mold cavity 111 is provided with a plurality of teeth 112 of varying heights. This allows for better limiting and positioning of the sides of the bird's claw and toes.

[0031] To ensure faster and more efficient mold closing and fixing of the poultry claws between the upper mold 2 and the bottom mold 1, matching guide pillars 3 and guide channels 4 are provided between the bottom mold 1 and the upper mold 2. Preferably, symmetrical guide pillars 3 are located on the upper mold 2, and corresponding guide channels 4 are located on the bottom mold 1. This simplifies the structure while ensuring sufficient length of the guide pillars 3 and guide channels 4 to achieve stability in mold closing.

[0032] In order to prevent the upper mold 2 from automatically sagging or completely separating from the bottom mold 1 due to centrifugal force during the automated debonding process, the guide channel 4 is equipped with a damping element 5 that matches the guide rail 3. The damping element 5 is fixed at the opening of the guide channel 4 by the fixing element 22 to prevent it from falling off.

[0033] In a preferred embodiment of this utility model, the bottom mold 1 is provided with a positioning hook 6 that connects to the large bone end of the bird's claw. The positioning hook 6 is rotatably connected to the bottom mold 1, and can open to release the bird's claw or close to hook the bird's claw during the rotation of the positioning hook 6.

[0034] Furthermore, the positioning hook 6 includes a left hook 61 and a right hook 62. The hook portions of the left hook 61 and the right hook 62 are rotatably connected, forming a V-shape when the bird's claw is released, such as... Figure 4 As shown in the image, the V-shape opens when hooking the bird's claw, as... Figure 1-3 As shown in the figure. In one specific embodiment, the ends of the claw mold cavity 10 are all open, and the positioning hook 6 is provided at the opening end of the large bone of the claw mold cavity 10. The V-shaped opening of the positioning hook 6 forms a receiving position for the continuation of the large bone. The pressure mold structure above the mold is provided with a pressing member (not shown in the figure) that can move and press the positioning hook 6 downward, pressing the free ends of the left hook 61 and the right hook 62 to the horizontal, so that the left hook 61 and the right hook 62 are closed, hooking the skin and flesh at the end of the large bone for fixation. The pressing member can also be provided on the frame, located above the positioning hook 6 of the fixed mold at this station, and the pressing member can move relative to the positioning hook 6.

[0035] To keep the positioning hook 6 closed during rotation, a locking structure is provided between the positioning hook 6 and the bottom mold 1 to lock the positioning hook 6 in the position of hooking the bird's claw. This locking structure can be a positioning pin 63 and positioning hole 64 structure between the positioning hook 6 and the fixing plate 7 on its outer side. Both the left hook 61 and the right hook 62 are provided. The top of the positioning pin 63 is spherical, and the positioning hole 64 is located at the corresponding horizontal locking position. When pressed into place, the spherical top of the positioning pin 63 engages with the positioning hole 64 to achieve a locked closed state. This locking structure can also be provided between the bottom mold 1 and the left hook 61 and the right hook 62. This locking structure can also be a snap-fit ​​with an abutting arc surface. When it is necessary to release the large bone, the pusher (not shown in the figure) set on the machine platform moves to push the free ends of the left hook 61 and the right hook 62, thereby unlocking the locking structure, so that the positioning hook 6 returns to its V shape, and the left hook 61 and the right hook 62 disengage from the large bone, releasing the large bone. The jacking component is located at the workstation on the machine frame where the claw lock needs to be unlocked. It pushes or pulls the left hook 61 and right hook 62 from below the positioning hook 6. The locking structure can also be other locking rotation structures, and elastic elements can be set between the locking structures to assist in locking or unlocking.

[0036] In use, this invention allows for the installation of multiple fixed molds on the automatic deboning machine for different processes. At the starting position, the poultry claw is placed into the corresponding cavity of the bottom mold 1. The control system controls the lifting drive of the upper mold 2 to maintain the separation distance between the upper mold 2 and the bottom mold 1, driving the upper mold 2 to close and fix the poultry claw. The lower toe mold 11 adjusts its position by sinking. Then, the top pressing component of the positioning hook 6 is driven down to open the positioning hook 6 and hook the large bone to lock, further fixing the poultry claw. Then, the deboning process is carried out. When the deboning is completed and the material is removed, the top pushing component of the positioning hook 6 is activated to unlock the positioning hook 6 and release the large bone. The lifting drive of the upper mold 2 causes the upper mold 2 to rise, opening the mold and allowing the deboned poultry claw to be removed.
