Description

Technical Field

[0001] This utility model relates to the field of food processing machinery, and in particular to a skinning mechanism for the end of the metatarsal bone of poultry. Background Technology

[0002] During the deboning process of poultry feet such as chicken feet and duck feet, incisions are first made in the skin corresponding to the metatarsal and phalangeal bones. Then, a deboning device is used to remove the metatarsal and phalangeal bones through these incisions. For the metatarsal bones, although incisions have been made in the skin, the bone itself is not fully exposed. During the removal of the metatarsal bones, the deboning device may inadvertently remove some skin and flesh, resulting in material loss and waste.

[0003] Therefore, it is necessary to design a structure for further processing of bird claws to fully expose the metatarsal bones in order to better facilitate deboning. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a peeling mechanism for the end of the metatarsal bone of a bird claw, including a bracket and two sets of peeling components arranged opposite to each other on the bracket. The peeling components include multiple swing rods arranged side by side. Each swing rod is rotatably connected to the bracket near the middle position. One end of each swing rod is provided with a peeling component, and the other end is connected to the bracket through an elastic component.

[0005] Furthermore, the peeling components in the peeling assembly are arranged sequentially from high to low, from the outside in.

[0006] Furthermore, the peeling components in the peeling assembly are arranged at the same height.

[0007] Furthermore, the bracket is provided with a connecting seat, the swing rod is provided with a through hole, and the swing rod is rotatably connected to the bracket through a pin passing through the connecting seat and the through hole.

[0008] Furthermore, the elastic element is a spring or a rubber band.

[0009] Furthermore, the peeling component is a columnar object, nail-like object, or hook-like object with a sharp bottom.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention uses two sets of oppositely arranged peeling components to peel the skin and flesh off the end of the metatarsal bone, exposing the end of the metatarsal bone. This makes it easier for the deboning device to grasp the metatarsal bone and remove it from the bird's foot, avoiding the waste of material caused by the inclusion of some skin and flesh.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0023] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. 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 a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0024] like Figure 1-2 As shown, the poultry claw metatarsal bone end peeling mechanism in this embodiment includes a bracket 1 and two sets of peeling components arranged opposite to each other on the bracket 1. The peeling components include multiple swing rods 2 arranged side by side. Each swing rod 2 is rotatably connected to the bracket 1 near the middle position. One end of each swing rod 2 is provided with a peeling component 3, and the other end is connected to the bracket 1 through an elastic component 4.

[0025] The support frame 1 is equipped with a connecting seat 5, and the swing rod 2 is equipped with a through hole 6. The swing rod 2 is rotatably connected to the support frame 1 through a pin 7 passing through the connecting seat 5 and the through hole 6. Multiple peeling components 3 in the peeling assembly are arranged sequentially from high to low, from the outside in. Depending on the length of the bird's claw, multiple peeling components 3 can participate in the peeling work simultaneously or partially. Due to the different heights of the various peeling components 3, the peeling component 3 closest to the end of the metatarsal bone will contact the metatarsal bone first, and then the other peeling components 3 will contact it in sequence, causing the epidermis to be gradually peeled off from the outside in.

[0026] The elastic element 4 can be a spring or a rubber band. In this embodiment, a spring is preferred. The spring can be either a tension spring or a compression spring. When a tension spring is used, one end of the tension spring is connected to the upper side of the bracket 1 and the other end is connected to the swing rod 2. When a compression spring is used, one end of the compression spring is connected to the lower side of the bracket 1 and the other end is connected to the swing rod 2.

[0027] In this embodiment, the peeling component 3 is a columnar object with a sharp bottom; such as Figure 3 As shown, in another embodiment, the peeling component 3 can be a nail-shaped object; as Figure 4 As shown, in another embodiment, the peeling component 3 can be a hook-shaped object. Example 2

[0028] like Figure 5 As shown in this embodiment, the multiple peeling parts 3 in the peeling assembly are all arranged at the same height. Other structures are as described in Embodiment 1, and will not be repeated here.

[0029] The elastic element 4 can be disposed on a protrusion on the bracket 1 at one end, as in Embodiment 1, and disposed in a through hole with a notch at the end of the swing rod 2 at the other end; or it can be disposed in a through hole on the bracket 1 at one end, as shown in this embodiment, and disposed in a through hole at the end of the swing rod 2 at the other end.

[0030] like Figure 6 As shown, in use, the poultry claw with the cut skin is fixed on the mold. A cylinder, hydraulic cylinder, or linear module drives the peeling mechanism to move downwards from above the metatarsal end of the claw. When the multiple peeling parts 3 of the two peeling components contact the metatarsal bone, the skin can be peeled downwards from both sides of the metatarsal end along the cut, thus fully exposing the metatarsal end. This facilitates the deboning device to grasp the metatarsal bone and remove it from the poultry claw, avoiding the waste of material caused by attaching some skin and meat.

[0031] By setting the elastic element 4, the peeling part 3 can be prevented from making hard contact with the metatarsal bone. When the peeling part 3 contacts the metatarsal bone, it is pushed upward. Under the leverage of the pin 7, the elastic element 4 at the other end is stretched (or compressed). The elastic element 4 will limit the peeling part 3 from being pushed up too much, thus ensuring that the peeling part 3 will not damage the bird's claws and can achieve the peeling effect.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. 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 claimed by this utility model.
