Description

Technical Field

[0001] This invention belongs to the field of food processing technology, and specifically relates to a deboning device for chicken feet. Background Technology

[0002] Chicken feet, also known as phoenix feet, are popular among consumers due to their high collagen content, nutritional value, and unique texture. The market demand for related processed products is increasing year by year. In the processing of chicken feet, the deboning step has a decisive impact on product quality, processing efficiency, and the final commercial value, making it a crucial step in the entire processing flow.

[0003] Currently, common methods for deboning chicken feet mainly include manual deboning and mechanical deboning. Manual deboning typically involves workers using knives or scissors to remove the bones from each chicken foot. While this method can maintain the integrity of the chicken meat to some extent, it suffers from high labor intensity and low processing efficiency. Furthermore, it is susceptible to variations in human operation, leading to inconsistent product quality and making it unsuitable for large-scale and continuous production. Mechanical deboning often uses rollers to beat or squeeze the meat, separating the bones from the meat tissue. While this method improves efficiency, it has significant drawbacks: firstly, uneven force often leaves some bone residue, resulting in incomplete deboning; secondly, repeated beating or squeezing can damage the chicken foot's tissue structure, causing the meat to become loose and its appearance to deteriorate, resulting in a "loose and collapsed" state, severely impacting the product's commercial value and market competitiveness.

[0004] In summary, existing methods for deboning chicken feet are either inefficient and produce inconsistent quality, or they damage the meat and result in incomplete deboning, making it difficult to balance processing efficiency and product quality. Therefore, we propose a chicken feet deboning device to solve these technical problems. Summary of the Invention

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example: See Figures 1-11 The present invention provides a chicken foot deboning device, including a deboning box 1, a rotary motor 2 is provided inside the deboning box 1, a turntable 3 is fixedly sleeved on the output shaft of the rotary motor 2, a plurality of fixtures 4 are evenly arranged around the turntable 3, and positioning grooves 5 matching the shape of chicken feet are opened on the fixtures 4. A chicken foot opening mechanism, a chicken foot deboning mechanism and a deboned chicken foot clamping mechanism are arranged sequentially along the circumference of the turntable 3 inside the deboning box 1. The positioning groove 5 includes a leg bone groove 501 and five toe grooves 502 that are dispersed and symmetrically connected to one end of the leg bone groove 501. The three middle toe grooves 502 are all inclined downward toward one end of the leg bone groove 501. The inner edges of the leg bone groove 501 and the toe grooves 502 are provided with serrations 6. The chicken claw opening mechanism and the chicken claw deboning mechanism are respectively arranged below the fixture 4, and a pressing mechanism is provided above the fixture 4 to press the chicken claws to carry out the opening and deboning processes of the chicken claws. The deboned chicken feet gripping mechanism is correspondingly arranged above the fixture 4, and is used to grip the deboned chicken feet out of the positioning groove 5; The deboning box 1 is provided with a bone collection groove 7 and a deboned chicken claw collection groove 8 below the chicken claw deboning mechanism and the deboned chicken claw clamping mechanism, respectively.

[0023] This chicken feet deboning equipment uses a deboning box 1 as its main body and a fixture 4 as the carrying unit for the chicken feet. The fixture 4 is evenly arranged around the circumference of a turntable 3. A rotary motor 2 drives the turntable 3 to rotate, causing the fixture 4 to move continuously, passing through three stations in sequence: opening, deboning, and collecting. This completes the opening, deboning, and collecting processes for the chicken feet in the positioning slots 5 of the fixture 4, achieving the chicken feet deboning process. Specifically, first, the worker loads the chicken feet into the positioning slots 5 of the fixture 4. As the turntable 3 starts, the fixture 4 is moved to the opening station. At this station, a pressing mechanism located above presses the chicken feet firmly to prevent movement or deformation, thus ensuring operational stability and the accuracy of the subsequent opening. Next, the chicken feet opening mechanism is activated, opening the chicken feet from below to expose the internal bones, creating conditions for the subsequent deboning process. After the opening is completed, fixture 4 follows turntable 3 into the deboning station. At this station, the chicken feet are pressed down by the upper pressing mechanism, and then the lower chicken foot deboning mechanism separates the bones from the chicken meat tissue. The separated bones fall into the bone collection trough 7 and are automatically discharged, while the complete deboned chicken feet remain in the positioning slot 5 of fixture 4. After deboning, fixture 4 continues to move to the collection station, where the deboned chicken feet are gripped from the positioning slot 5 by the deboned chicken feet clamping mechanism and sent into the deboned chicken feet collection trough 8, completing the collection of the deboned chicken feet. At this point, a complete chicken foot deboning process is finished. Workers only need to continuously put chicken feet to be deboned into the empty fixture 4, and with the continuous rotation of turntable 3, continuous, assembly-line processing of chicken feet deboning is achieved. Compared to traditional manual deboning or mechanical deboning methods involving rollers and pressure, this chicken feet deboning equipment, through the coordination of a turntable 3, a chicken feet opening mechanism, a chicken feet deboning mechanism, and a deboned chicken feet clamping mechanism, eliminates the need for repeated patting or pressure during the deboning process. This avoids damaging the chicken feet's tissue structure, effectively solving the problems of loose meat and poor appearance, and ensuring product integrity and appearance quality. Furthermore, the multi-station parallel operation ensures a stable and efficient overall processing flow, resulting in consistent product quality. This not only improves production efficiency but also enhances the commercial value and market competitiveness of chicken feet products, making it particularly suitable for large-scale continuous production. Notably, the positioning groove 5 of the fixture 4 is designed according to the structural characteristics of chicken feet, including a leg bone groove 501 and five toe grooves 502. This design includes one more toe groove 502 than the chicken feet themselves, allowing the fixture 4 to accommodate both left and right chicken feet, eliminating the need for manual differentiation and improving loading efficiency. The three middle toe grooves 502 are all angled downwards towards the end of the leg bone groove 501, facilitating smooth separation of the bone after opening. Meanwhile, the inner edges of the leg bone groove 501 and the toe groove 502 are provided with a serrated structure 6, which can prevent the chicken meat tissue from falling out on the one hand, and leave a gap for the bone on the other hand, so that the bone can fall off smoothly during the peeling process, thereby effectively ensuring that the finished product is intact and the deboning is thorough.

[0024] In one specific implementation, see Figures 4-7The chicken claw opening mechanism includes three sets of main toe opening components 9 and one set of big toe opening components 10, which are evenly and continuously arranged along the circumference of the turntable 3 to realize the opening operations of the left toe, right toe, middle toe and leg bone, and big toe of the chicken claw, respectively.

[0025] The chicken claw opening mechanism includes three sets of main toe opening components 9 and one set of big toe opening components 10, which respectively realize the opening operations of the left toe, right toe, middle toe and leg bone, and big toe of the chicken claw. That is, the left toe, right toe, middle toe and leg bone, and big toe of the chicken claw are opened separately. This partitioned arrangement ensures that each opening action is carried out independently without interference, avoids cross-operation space, thereby ensuring the opening effect and facilitating deboning.

[0026] In one specific implementation, see Figures 4-6 The main toe opening assembly 9 includes a first cylinder 901, an electric slide rail 902, a main toe opening knife holder 903, and a main toe opening knife 904. The first cylinder 901 is correspondingly disposed below the fixture 4. The electric slide rail 902 is installed at the output end of the first cylinder 901 and is arranged inclined upward toward the chicken claw toe tip. Among them, the electric slide rails 902 of the three sets of main toe opening components 9 are respectively set below the corresponding toe grooves 502 of the three middle main toes and are parallel to the axial direction of the corresponding toe grooves 502. The stroke of the electric slide rail 902 of the middle main toe opening component 9 is from the end of the leg bone groove 501 to the end of the middle toe groove 502. The main toe opening cutter holder 903 is connected to the slider of the electric slide rail 902, and the main toe opening cutter 904 is elastically connected to the main toe opening cutter holder 903.

[0027] Specifically, the main toe opening assembly 9 consists of a first cylinder 901, an electric slide rail 902, a main toe opening cutter holder 903, and a main toe opening cutter 904. The electric slide rails 902 of the three main toe opening assemblies 9 correspond to the toe grooves 502 of the three middle main toes, and are evenly and continuously arranged along the circumference of the turntable 3 in the order of left, right, and center, and are installed at an angle upward towards the toe tip of the chicken claw to match the downward slope design of the three middle toe grooves 502 towards the leg bone groove 501. During the opening operation, firstly, the first cylinder 901 is activated, raising the electric slide rail 902 and the main toe opening cutter holder 903 and main toe opening cutter 904 on it to the bottom of the fixture 4, so that the main toe opening cutter 904 is attached to the skin of the chicken claw's main toe. Subsequently, the electric slide rail 902 drives the slider to slide along a preset trajectory, and the main toe opening knife holder 903 and the main toe opening knife 904 move accordingly, gradually increasing in height with the slope, always maintaining close contact with the chicken claw skin for opening operations, ensuring the accuracy of the opening. At the same time, the main toe opening knife 904 is elastically connected to the main toe opening knife holder 903, providing appropriate cushioning during the process of cutting the chicken claw skin, avoiding damage to the bone, reducing blade wear, and extending the service life of the main toe opening knife 904. It is worth mentioning that the positioning groove 5 is composed of a leg bone groove 501 and five toe grooves 502 dispersed and symmetrically connected to one end of the leg bone groove 501, with the leg bone groove 501 and the middle toe groove 502 located on the same axis. To address this structural feature, the main toe opening assembly 9, parallel to the toe groove 502 corresponding to the middle main toe, employs a larger-stroke electric slide rail 902. This allows the main toe opening cutter 904 to have a greater range of motion, enabling it to cover the chicken claw leg bone and the lower epidermis of the middle main toe, achieving effective opening and creating conditions for bone removal. Furthermore, see [reference needed]. Figure 6 The main toe opening component 9, corresponding to the middle main toe, can also use a double-headed cutter on the main toe opening cutter holder 903 to achieve simultaneous opening of the chicken claw leg bone and the middle main toe, further improving the opening efficiency.

[0028] In one specific implementation, see Figure 7 The big toe opening assembly 10 includes a second cylinder 1001, a second double-slider linear guide 1002, a big toe opening cutter holder 1003, and a big toe opening cutter 1004. The second cylinder 1001 is correspondingly disposed below the fixture 4. The second double-slider linear guide 1002 is horizontally mounted on the output end of the second cylinder 1001. The second double-slider linear guide 1002 is disposed below the corresponding big toe groove 502 and is parallel to the axial direction of the corresponding big toe groove 502. The two sliders on the second double-slider linear guide 1002 are symmetrically disposed and each is provided with a big toe opening cutter holder 1003. The big toe opening cutter 1004 is elastically connected to the big toe opening cutter holder 1003.

[0029] Specifically, the big toe opening assembly 10 consists of a second cylinder 1001, a second double-slider linear guide 1002, a big toe opening cutter holder 1003, and a big toe opening cutter 1004. The second double-slider linear guide 1002 is set parallel to the toe groove 502 corresponding to the big toe, and the two sliders on it run synchronously. The big toe opening cutter holder 1003 is installed on both sliders, and the big toe opening cutter 1004 is installed on the big toe opening cutter holder 1003. During the opening operation, the second cylinder 1001 drives the second double slider linear guide 1002 and its big toe opening tool holder 1003 and big toe opening tool 1004 to rise below the fixture 4. Since both sliders are equipped with big toe opening tool holders 1003 with big toe opening tools 1004, regardless of whether the big toe of the chicken claw is located in the toe groove 502 on the left or right side, one of the big toe opening tools 1004 is attached to the skin of the chicken claw's big toe. As the slider slides, it performs the opening operation on the chicken claw along the direction of the toe groove 502, thereby avoiding the need to distinguish between the left and right chicken claws and effectively improving the overall processing efficiency.

[0030] In one specific implementation, see Figures 4-10 The pressing mechanism includes a bracket 11 and a thin cylinder 12 mounted on the bracket 11. The output end of the thin cylinder 12 is arranged facing downward and connected to a pressing plate 13. Slide rods 14 are vertically connected to all four sides of the top surface of the pressing plate 13. The other end of the slide rods 14 is movably mounted on the bracket 11. The bottom surface of the pressing plate 13 is provided with a pressing mold 15 that matches the positioning groove 5.

[0031] The pressing mechanism uses a thin cylinder 12 to drive the pressing plate 13 to move downward. Under the guidance of the slide rod 14, the pressing plate 13 can maintain a stable and vertical linear movement, effectively avoiding deviation or tilting. This ensures that the pressing mold 15 can stably and accurately press the chicken claw in the fixture 4, improving the processing quality of opening and deboning, and providing a guarantee for achieving efficient and stable continuous production.

[0032] In one specific implementation, see Figures 8-10 The chicken claw deboning mechanism includes a big toe peeling component 16, a three-major-toe peeling component 17, and a leg bone peeling component 18, which are evenly and continuously arranged along the circumference of the turntable 3 to realize the big toe peeling, three-major-toe peeling, and leg bone peeling operations of the chicken claw, respectively.

[0033] The chicken claw deboning mechanism consists of a big toe peeling component 16, a three-major-toe peeling component 17, and a leg bone peeling component 18, which respectively perform the big toe peeling, three-major-toe peeling, and leg bone peeling operations of the chicken claw. This partitioned arrangement ensures that each peeling action is carried out independently without interference, avoids cross-operation space, thereby ensuring the peeling effect, reducing rework, and improving production efficiency.

[0034] In one specific implementation, see Figure 8 The big toe peeling assembly 16 includes a third cylinder 1601, a third double-slider linear guide 1602, a big toe peeling knife holder 1603, and a big toe peeling knife 1604. The third cylinder 1601 is correspondingly disposed below the fixture 4. The third double-slider linear guide 1602 is horizontally mounted on the output end of the third cylinder 1601. The third double-slider linear guide 1602 is disposed below the big toe groove 502 and parallel to the axial direction of the corresponding toe groove 502. The two sliders on the third double-slider linear guide 1602 are symmetrically arranged and each is provided with a big toe peeling knife holder 1603. The big toe peeling knife 1604 is connected to the big toe peeling knife holder 1603.

[0035] Specifically, the big toe peeling assembly 16 consists of a third cylinder 1601, a third double-slider linear guide rail 1602, a big toe peeling knife holder 1603, and a big toe peeling knife 1604. The third double-slider linear guide rail 1602 is set parallel to the toe groove 502 corresponding to the big toe, and the two sliders on it run synchronously. The big toe peeling knife holder 1603 is installed on both sliders, and the big toe peeling knife 1604 is installed on the big toe peeling knife holder 1603. During the peeling operation, the third cylinder 1601 drives the third double slider linear guide 1602 and its big toe peeling tool holder 1603 and big toe peeling tool 1604 to rise below the fixture 4. Since both sliders are equipped with big toe peeling tool holders 1603 with big toe peeling tools 1604, regardless of whether the big toe of the chicken claw is located in the toe groove 502 on the left or right side, one of the big toe peeling tools 1604 is attached to the end of the big toe bone of the chicken claw. As the slider slides, the chicken claw is peeled along the direction of the toe groove 502, thereby avoiding the need to distinguish between the left and right chicken claws and effectively improving the overall processing efficiency.

[0036] In one specific implementation, see Figure 9 The three-major toe stripping assembly 17 includes a first support base 1701, a major toe stripping cylinder 1702, and a major toe stripping cutter 1703. The first support base 1701 is disposed inside the bone removal box 1. The major toe stripping cylinder 1702 is installed on the top surface of the first support base 1701 and is arranged obliquely upward from the leg bone groove 501 toward the middle toe groove 502. The major toe stripping cutter 1703 is installed at the output end of the major toe stripping cylinder 1702, and the major toe stripping cutter 1703 abuts against the bottom surface of the three middle toe grooves 502.

[0037] Specifically, the three-major toe peeling assembly 17 consists of a first support base 1701, a major toe peeling cylinder 1702, and a major toe peeling cutter 1703. By mounting the major toe peeling cylinder 1702 on the top surface of the first support base 1701 and arranging it obliquely upward along the leg bone groove 501 toward the middle toe groove 502, the major toe peeling cutter 1703 at its output end can fit against the bottom surface of the three middle toe grooves 502 during operation. The major toe peeling cylinder 1702 drives the major toe peeling cutter 1703 to push the three-major toe bones to rotate along a predetermined trajectory, thereby realizing the separation of the chicken claw epidermis from the three-major toe bones.

[0038] In one specific implementation, see Figure 10 The leg bone stripping assembly 18 includes a second support base 1801, a leg bone stripping cylinder 1802, and a leg bone stripping cutter 1803. The second support base 1801 is disposed inside the bone stripping box 1. The leg bone stripping cylinder 1802 is horizontally mounted on the top surface of the second support base 1801. The leg bone stripping cutter 1803 is mounted on the output end of the leg bone stripping cylinder 1802, and the leg bone stripping cutter 1803 abuts against the bottom surface of the leg bone groove 501.

[0039] Specifically, the leg bone separation assembly 18 consists of a second support base 1801, a leg bone separation cylinder 1802, and a leg bone separation cutter 1803. The leg bone separation cylinder 1802 is horizontally mounted on the top surface of the second support base 1801, and the leg bone separation cutter 1803 at its output end is attached to the bottom surface of the leg bone groove 501. During operation, the leg bone separation cylinder 1802 drives the leg bone separation cutter 1803 to rotate the leg bone along a predetermined trajectory, thereby achieving the separation of the chicken claw skin from the leg bone.

[0040] In one specific implementation, see Figure 3 and Figure 11 The deboned chicken feet clamping mechanism includes a lifting cylinder 19, a support rod 20, a sliding cylinder 21, and a mechanical clamp 22. The lifting cylinder 19 is correspondingly arranged below the fixture 4. The output end of the lifting cylinder 19 is provided with an upward push mold 23 that matches the positioning groove 5. The support rod 20 is arranged inside the deboning box 1. The sliding cylinder 21 is installed on the support rod 20 and is arranged parallel to the axial line connecting the lifting cylinder 19 and the deboned chicken feet collection groove 8. The mechanical clamp 22 is installed on the slider of the sliding cylinder 21.

[0041] The deboned chicken feet gripping mechanism consists of a lifting cylinder 19, a support rod 20, a sliding cylinder 21, and a mechanical clamp 22.
