Description

Technical Field

[0001] The utility model relates to the technical field of poultry cutting devices, in particular to a skin lifting mechanism for a chicken leg cutting machine. Background Technique

[0002] In food processing, whole poultry usually needs to be cut into different parts for sale, such as legs, wings, and breast meat. This cutting operation is usually completed by an automatic cutting production line. The thighs of broiler chickens usually need to be skinned. There is a significant price difference between the leg skin and the lower legs. Usually, the price of the lower legs is significantly more than twice that of the leg skin. In order to achieve more refined sales, chicken legs usually also need to be cut into thighs and lower legs for separate sale. Existing automatic chicken leg cutting machines usually hang the whole chicken leg on a hook, with the lower leg facing up and the thigh facing down. A fixing mechanism is used to limit the position of the leg, and then a cutter is aligned with the connection part between the thigh and the lower leg for cutting. Chinese Patent 2023218362891 discloses "A Poultry Thigh and Lower Leg Cutting Device", and the publication number is CN220211705U. This cutting device includes: a leg conveying mechanism for conveying poultry legs; a leg limiting mechanism arranged below the leg conveying mechanism for limiting the position of poultry legs to prevent the poultry legs from rotating; a leg cutting mechanism arranged on one side of the leg limiting mechanism for cutting the thighs and lower legs of poultry; and a slitting mechanism for increasing the bone slit at the connection between the thighs and lower legs of poultry to facilitate accurate cutting by the leg cutting mechanism. There is a very slippery mucous membrane between the chicken skin and the chicken leg meat of fresh chicken legs. With a very small force, the chicken skin can be slid. After slaughter, the chicken skin of broiler chickens is very loose. When the chicken leg is hung upside down on the cutting mechanism, the chicken skin naturally droops. The chicken skin on the lower leg is stretched and piled up on the thigh part. After cutting, the chicken skin on the lower leg rebounds, and the chicken skin on the thigh and the lower leg is unevenly divided, which not only affects the appearance of the product but also causes a decrease in weight due to the lack of chicken skin on the lower leg, affecting the revenue. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a skin lifting mechanism for a chicken leg cutting machine that lifts the chicken skin before cutting the chicken leg, significantly extending the chicken skin on the lower leg after cutting to meet the needs of production enterprises.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Such as Figure 1As shown, the utility model discloses a skin-lifting mechanism for a chicken leg splitting machine, which includes a brush roller 1. The brush roller 1 is a nylon brush roller with a columnar structure. The brush roller 1 is a nylon brush roller installed on a speed regulating motor 2 through a coupling, and can also be a rotating roller with teeth or thorns. The speed regulating motor 2 can accurately control the rotation speed. When in use, the position of the brush roller 1 is relatively fixed, and the chicken leg 9 to be split is hung on the conveyor belt and moves horizontally. When the chicken leg 9 moves to the skin-lifting position, one side of the brush roller 1 is close to the side of the calf of the chicken leg 9 to be split. The speed regulating motor 2 rotates, and the side of the brush roller 1 rubs the side of the chicken leg 9 from bottom to top, and the chicken skin on the chicken leg 9 is pulled upward. Subsequently, the chicken leg 9 continues to move toward the direction of the cutter, and the thigh and calf are cut immediately before the chicken skin after lifting has drooped, so that the chicken skin on the cut calf can be completely retained.

[0031] like Figure 1 , Figure 2 , Figure 3 As shown, the speed regulating motor 2 is fixedly mounted on the motor mounting plate 3, and the motor mounting plate 3 is a U-shaped structure, which is convenient for installing the speed regulating motor 2 into the motor mounting plate 3 through the opening of the U-shaped structure. The motor mounting plate 3 is floatingly mounted on the motor bracket 4 through the elastic body 6, and the motor bracket 4 is mounted in front of the cutter in the chicken leg splitting machine through the mounting frame 5. The elastic body 6 has a certain elasticity, so that the motor mounting plate 3 and the speed regulating motor 2 have a certain floating displacement when subjected to force, automatically adapt to chicken legs 9 of different sizes, and can obtain appropriate skin lifting friction for chicken legs 9 of different sizes.

[0032] like Figure 4 As shown, the elastic body 6 is a U-shaped spring sheet, the motor bracket 4 includes a bottom plate 41, a side panel 42 fixedly connected to the upper surface of the bottom plate 41, one end of the U-shaped spring sheet is fixedly connected to the upper surface of the bottom plate 41, and the other end is fixedly connected to the motor mounting plate 3, the side panel 42 is one or more plates of an integrated structure with the bottom plate 41, and is arranged around the motor mounting plate 3, and a motor limiting mechanism is arranged between the side panel 42 and the speed regulating motor 2. The motor limiting mechanism is a top screw 43 located at the rear end of the speed regulating motor 2 and connected to the side panel 42 by threading. The top screw 43 is inserted through the side panel 42, and the top screw 43 is adjusted, and the front end of the top screw 43 is pressed against the rear end of the speed regulating motor 2 to fine-tune the position of the speed regulating motor 2. Of course, the motor limiting mechanism can also be arranged on the side of the speed regulating motor 2 as needed.

[0033] As another embodiment of the utility model, the elastic body 6 can also be a coil spring or a group of permanent magnets with the same polarity arranged opposite to each other. When the coil spring is used, one end of the coil spring is fixedly connected to the upper surface of the bottom plate 41, and the other end is fixedly connected to the motor mounting plate 3.

[0034] The mounting bracket 5 is used to connect the chicken skin lifting mechanism to the chicken leg cutting machine. As Figure 2 , Figure 3 shown, the mounting bracket 5 includes an upper mounting plate 51 and a lower mounting plate 52 which are perpendicularly arranged and fixedly connected together. The upper mounting plate 51 and the lower mounting plate 52 are perpendicularly arranged in a right-angled folding plate shape. The motor bracket 4 is mounted on the lower mounting plate 52, and the upper mounting plate 51 is connected to the chicken leg cutting machine by bolts. The lower mounting plate 52 is provided with fastening bolt holes and limit bolt holes 53. The limit bolt holes 53 are arc-shaped long holes centered on the fastening bolt holes. The motor bracket 4 is provided with fastening bolts 44 and limit bolts 45. The ends of the fastening bolts 44 and limit bolts 45 are fixedly welded to the outer side surface of the motor bracket 4. The fastening bolts 44 are installed in the fastening bolt holes and fixed with nuts. The limit bolts 45 are installed in the limit bolt holes and fixed with nuts. By loosening the nuts on the fastening bolts 44 and limit bolts 45, the limit bolts 45 can slide in the arc-shaped long holes of the limit bolt holes 53 to change the inclination angle of the motor bracket 4. Tightening the nuts on the fastening bolts 44 and limit bolts 45 can fix the position of the motor bracket 4.

[0035] As Figures 5 - 7 shown, the chicken skin lifting mechanism is installed on the fixed bracket 91 of the chicken leg cutting machine through the mounting bracket 5. The upper mounting plate 51 of the mounting bracket 5 is connected to the fixed bracket 91 by bolts. After installation, the brush roller 1 is located in front of the cutting knife 92 of the chicken leg cutting machine, and the position is as close as possible to the position where the cutting knife 92 starts to cut the chicken leg. One side of the brush roller 1 faces the direction of the chicken leg hanging on the hook 93. When the chicken leg moves to the position of the brush roller 1 along with the hook 93, the side of the brush roller 1 facing the chicken leg pulls up the chicken skin on the surface of the chicken leg from bottom to top. Since the chicken leg is always in a moving state, but the position of the brush roller 1 is relatively fixed, in order to obtain a better chicken skin lifting effect, the brush roller 1 can be inclined so that the outer linear velocity of the brush roller in the horizontal direction is equal to or slightly greater than the conveying speed of the chicken leg. In this way, it can be ensured that the speed at which the brush roller 1 pulls up the chicken skin catches up with or exceeds the conveying speed of the chicken leg, realizing effective lifting of the chicken skin. After the chicken skin is lifted up, it is cut by the cutting knife 92 within a very short time. In this way, more chicken skin can be retained on the upper half part of the chicken leg, that is, the lower leg part, meeting the requirements of improving the appearance and increasing the income.
