Description

Technical Field

[0001] The utility model relates to the field of food processing equipment, in particular to a novel poultry claw joint cartilage removal mechanism. Background Art

[0002] During the deboning process of poultry feet such as chicken feet and duck feet, there is a piece of cartilage at the terminal joint of the metatarsal bones of the poultry feet, which is directly connected to the skin and flesh of the poultry feet. During the deboning process, if the metatarsal bones are directly pulled outwards, the cartilage will involve part of the skin and flesh, causing waste of food. If the cartilage can be removed before deboning, the above problem can be avoided, thereby saving food.

[0003] To this end, the patent CN216983381U previously applied by the applicant discloses a poultry claw joint cartilage removal device. Although it can also achieve the removal of cartilage, the structure is still somewhat complicated and needs to be further simplified to improve work efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model discloses a novel mechanism for removing cartilage from poultry claw joints, comprising a base, a bone removing piece and an elastic piece, the base being provided with a connecting portion, the bone removing piece being rotatably connected to the connecting portion via a pin shaft, a positioning groove being provided on the connecting portion at the upper side of the pin shaft, the elastic piece being arranged in the positioning groove, and one end of the elastic piece being abutted against the inner wall of the positioning groove, and the other end being movably connected to the end of the bone removing piece, and a hook-shaped portion being provided at the front end of the bone removing piece.

[0005] Furthermore, a guide member is provided at the position where the elastic member contacts the bone removing member.

[0006] Furthermore, the base is provided with a connecting hole.

[0007] Furthermore, the number of the bone removing member and the elastic member is one or more.

[0008] The beneficial effects of the utility model are:

[0009] The utility model hooks the articular cartilage at the end of the metatarsal bone by the deboning piece on the base, and moves the base downward to remove the articular cartilage from the end of the metatarsal bone. During the downward movement, the elastic piece has a buffering effect on the deboning piece, preventing the deboning piece from hooking on the bone and causing damage to the equipment or the bird's claws. The deboning mechanism has a simple and reliable structure and can effectively separate the articular cartilage from the metatarsal bone and skin and flesh, avoiding the problem of food waste caused by the involvement of skin and flesh by the articular cartilage during the deboning process.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0020] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Embodiment 1

[0021] like Figure 1-2 As shown, the novel poultry claw articular cartilage removal mechanism in this embodiment includes a base 1, a bone removal piece 2 and an elastic piece 3; a connecting portion 4 is provided on the base 1, and the bone removal piece 2 is rotatably connected to the connecting portion 4 through a pin shaft 5; a positioning groove 6 is provided on the connecting portion 4 at the upper side of the pin shaft 5, and the elastic piece 3 is arranged in the positioning groove 6, and one end of the elastic piece 3 abuts against the inner wall of the positioning groove 6, and the other end is movably connected to the end of the bone removal piece 2; a hook-shaped portion 7 is provided at the front end of the bone removal piece 2 for hooking the articular cartilage during bone removal; a guide piece 8 is also provided at the position where the elastic piece 3 contacts the bone removal piece 2, and a connecting hole 9 is also provided on the base 1 for fixed connection with the driving unit.

[0022] The elastic member 3 may be an elastic element such as a spring or a rubber column; the guide member 8 is a structure with an arc surface or a spherical surface, such as a steel ball or a roller, so as to reduce the friction between the guide member 8 and the bone removal member 2 .

[0023] In this embodiment, the number of the bone-removing pieces 2 and the number of the elastic pieces 3 are both three. The three elastic pieces 3 are respectively disposed in the three positioning grooves 6 , and a bone-removing piece 2 is correspondingly disposed at the front end of each elastic piece 3 . Embodiment 2

[0024] like Figure 3 As shown, different numbers of deboning pieces 2 and elastic pieces 3 can be provided according to the size, number and actual processing conditions of the poultry claws. In this embodiment, two positioning grooves 6 are provided on the connecting portion 4, each of which is provided with an elastic piece 3, and two deboning pieces 2 are provided at the front end of each elastic piece 3. Embodiment 3

[0025] like Figure 4 As shown, in this embodiment, a positioning groove 6 is provided on the connecting portion 4, an elastic member 3 is provided in the positioning groove 6, and a bone removing member 2 is provided at the front end of the elastic member 3.

[0026] The working principle of the present invention is briefly described below in conjunction with the above embodiments:

[0027] like Figure 5 As shown, when the mechanism is used, it can be installed on a driving unit (such as a pneumatic cylinder, an oil cylinder, a linear motor, etc.), and the driving unit drives the mechanism to move up and down.

[0028] In the initial state, the deboning member 2 is in a horizontal or nearly horizontal state under the action of the elastic member 3, and the poultry claw to be deboned is fixed on the mold so that its end is located below the hook 7 of the deboning member 2. When the driving unit drives the mechanism to move downward, the hook 7 hooks the joint between the bone and the articular cartilage, and as the mechanism continues to move downward, the deboning member 2 can peel the articular cartilage off the bone; after the deboning is completed, the driving unit drives the mechanism to reset.

[0029] The setting of the elastic member 3 can play a protective role. If the hook-shaped portion 7 is hooked on the bone, the bone removal piece 2 can be rotated upward around the pin 5 at a certain angle. At the same time, the hook-shaped portion 7 will slide downward along the end of the bone until it enters the joint between the bone and the articular cartilage, avoiding rigid contact between the hook-shaped portion 7 and the bone, thereby avoiding damage to the mechanism or the poultry claw.

[0030] In summary, the deboning mechanism has a simple and reliable structure and can effectively separate articular cartilage from metatarsal bones and flesh, thereby avoiding the problem of food waste due to articular cartilage involving flesh during the deboning process.

[0031] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
