Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of poultry cutting device, in particular to a skin lifting mechanism for chicken leg cutting machine. BACKGROUND

[0002] In food processing, whole poultry is usually cut into different parts for sale, such as legs, wings and breasts, and this cutting operation is usually completed by an automatic cutting production line. The price of the large leg of a meat chicken is significantly different from that of the small leg, and the price of the small leg is usually significantly higher than that of the large leg. In order to achieve more refined sales, the chicken leg usually needs to be cut into a large leg and a small leg for separate sales. The existing automatic chicken leg cutting machine usually hangs the whole chicken leg on a hook with the small leg facing up and the large leg facing down, and then cuts the connecting part of the large leg and the small leg by a cutter after the leg is positioned by a fixed mechanism. Chinese patent 2023218362891 discloses a poultry thigh and small leg cutting device, and the publication number is CN220211705U. The cutting device includes a leg conveying mechanism for conveying poultry legs, a leg limiting mechanism arranged below the leg conveying mechanism for limiting the 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 poultry large leg and small leg, and a gap opening mechanism for increasing the bone gap of the connecting part of the poultry large leg and small leg to facilitate accurate cutting by the leg cutting mechanism. There is a very smooth mucosa between the skin of a fresh chicken leg and the chicken leg meat, and the skin can be easily slid by applying a small force. After being slaughtered, the skin of the meat chicken is very loose. When the chicken leg is hung on the cutting mechanism, the skin naturally droops, and the skin on the small leg is stretched and accumulated on the large leg part. After cutting, the skin on the small leg rebounds, and the skin on the large leg and the small leg is not evenly divided, which not only affects the appearance of the product, but also causes the weight of the small leg to decrease due to the lack of skin, affecting the income.

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0029] As Figure 1As shown, the skin lifting mechanism for chicken leg cutting machine of the present application comprises a brush roller 1, which is installed on a speed regulating motor 2 through a coupling. The brush roller 1 can also be a gear or thorn roller. The speed regulating motor 2 can accurately control the rotating speed. In use, the position of the brush roller 1 is relatively fixed. The chicken leg 9 to be cut is horizontally moved on a conveying belt. 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 shank of the chicken leg 9 to be cut. The speed regulating motor 2 is rotated. The side of the brush roller 1 rubs the side of the chicken leg 9 from bottom to top, thereby lifting the chicken skin on the chicken leg 9 upward. Then, the chicken leg 9 continues to move to the cutting position. The cutting of the thigh and shank is performed immediately when the lifted chicken skin has not yet fallen down, thereby completely retaining the chicken skin on the shank after cutting.

[0030] As shown in Figure 1 , Figure 2 , Figure 3 , the speed regulating motor 2 is fixedly installed on a motor mounting plate 3, which is in a U-shaped structure. The U-shaped structure facilitates the installation of 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 installed on a motor support 4 through an elastic body 6. The motor support 4 is installed in front of the cutting knife in the chicken leg cutting machine through a mounting bracket 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, thereby automatically adapting to chicken legs 9 of different sizes and obtaining appropriate skin lifting friction force for chicken legs 9 of different sizes.

[0031] As shown in Figure 4 , the elastic body 6 is a U-shaped spring sheet. The motor support 4 comprises a bottom plate 41 and a side wall plate 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 wall plate 42 is in an integrated structure with the bottom plate 41 and is a plate body or several plate bodies surrounding the motor mounting plate 3. A motor limiting mechanism is arranged between the side wall plate 42 and the speed regulating motor 2. The motor limiting mechanism is a top pin 43 located at the rear end of the speed regulating motor 2 and threadedly connected to the side wall plate 42. The top pin 43 is inserted through the side wall plate 42. By adjusting the top pin 43, the front end of the top pin 43 abutting against the rear end of the speed regulating motor 2 can finely adjust 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 according to the need.

[0032] As another embodiment of the present application, the elastic body 6 can also be a helical spring or a group of permanent magnets with opposite polarities arranged oppositely. When the helical spring is adopted, one end of the helical 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.

[0033] The mounting bracket 5 is used to connect the skin lifting mechanism to the chicken leg cutting machine. As shown inFigure 2 , Figure 3 As shown, the mounting frame 5 includes an upper frame plate 51 and a lower frame plate 52 that are perpendicularly arranged and fixedly connected together. The upper frame plate 51 and the lower frame plate 52 are perpendicular to each other and form a right-angled folded plate shape. The motor bracket 4 is mounted on the lower frame plate 52, and the upper frame plate 51 is bolted to the chicken leg splitter. The lower frame plate 52 is provided with fastening bolt holes and limiting bolt holes 53. The limiting bolt holes 53 are arc-shaped elongated holes centered on the fastening bolt holes. The motor bracket 4 is provided with fastening bolts 44 and limiting bolts 45. The ends of the fastening bolts 44 and limiting bolts 45 are fixedly welded to the outer surface of the motor bracket 4. The fastening bolts 44 are installed in the fastening bolt holes and fixed with nuts, and the limiting bolts 45 are installed in the limiting bolt holes and fixed with nuts. Loosen the nuts on the fastening bolt 44 and the limiting bolt 45. The limiting bolt 45 can slide in the arc-shaped elongated hole of the limiting bolt hole 53 to change the tilt angle of the motor bracket 4. Tighten the nuts on the fastening bolt 44 and the limiting bolt 45 to fix the position of the motor bracket 4.

[0034] like Figures 5-7 As shown, the skin-lifting mechanism is mounted on the fixed bracket 91 of the chicken leg splitting machine via a mounting frame 5. The upper plate 51 of the mounting frame 5 is bolted to the fixed bracket 91. After installation, the brush roller 1 is positioned in front of the cutter 92 of the chicken leg splitting machine, as close as possible to the position where the cutter 92 begins to cut the chicken leg. One side of the brush roller 1 faces the chicken leg hanging on the hook 93. When the chicken leg moves to the position of the brush roller 1 with the hook 93, the side of the brush roller 1 facing the chicken leg lifts the chicken skin from bottom to top. Since the chicken leg is always in motion, but the position of the brush roller 1 is relatively fixed, in order to achieve a better skin-lifting effect, the brush roller 1 can be tilted so that the horizontal linear velocity of the outer edge of the brush roller is equal to or slightly greater than the speed of the chicken leg conveying. This ensures that the speed at which the brush roller 1 lifts the chicken skin upward keeps up with or exceeds the speed of the chicken leg conveying, thus achieving effective skin lifting. After the chicken skin is lifted up, it is cut by the 92-inch cutter in a very short time. This allows more chicken skin to be retained in the upper part of the chicken leg, that is, the lower leg, which meets the requirements of improving appearance and increasing profits.
