Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a special processing device for chicken wing roots. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] Due to consumer demand, the processing of chicken wing root products currently requires further cutting of the chicken meat on both sides of the wing root. The cutting steps are as follows:

[0004] Make a cut at a specified distance from the tip of the small bone at the wing root, and cut along the inner bone of the wing root toward the tip of the large bone at the wing root.

[0005] Then, on the other side of the wing root endoskeleton, begin cutting towards the large bone end of the wing root using the same method as the first cut.

[0006] After being cut open, the chicken meat connecting the two sides of the inner bone of the wing root is spread out, and the thickness is generally 2-5 mm.

[0007] The above processing relies on manual cutting. In order to automate the cutting, a wing root processing device and method with publication number CN116998527A has been proposed on the market. This processing device can set a clamping plate to fix the wing root on the conveying mechanism, and a spring pressure plate is used to press down the small end of the wing root to prevent it from lifting up during the cutting process. The cutter is used to cut the chicken meat on both sides of the inner bone of the wing root at the same time. The cutting is completed while the wing root moves with the conveying mechanism, without the need for extra cutting actions.

[0008] While the aforementioned wing root processing device can improve the level of automation, it suffers from technical problems such as poor cutting stability and low conveying efficiency during the cutting process. The specific technical problems are as follows:

[0009] (1) The original tool holder limiting ring is made of a layer of steel plate. There is a large gap between the limiting ring and the first fixed frame. During the process of the cylinder driving the tool holder to cut, the tool is simultaneously subjected to the resistance of the conveyor belt in the direction of travel. The first fixed frame is offset within the limiting ring, making the entire tool holder easy to move and affecting the cutting effect of the next wing root.

[0010] (2) The operator needs to place the chicken wing raw material on the clamp plate and place the chicken wing raw material in the container outside the processing device. The container is placed on one side of the conveyor belt. The operator needs to bend over or turn around to pick up the chicken wings. After the material in one container is processed, it needs to be transferred to other containers. The operator's movements are large, which increases the labor intensity of the operator. In addition, the wing root processing device adopts a single-station cutting device. The cutting device is equipped with a chain plate conveyor belt. Only one employee can operate at a time, which results in low work efficiency.

[0011] (3) The clamps fix the chicken wing root only through the clamps at both ends. The small bone end is located at the first clamp and the large bone end of the wing root is located at the second clamp. Although it can fix the length direction, due to the irregular surface and internal tissue structure of the chicken wing root, when the cutter cuts into the wing root, the blade rubs against the wing root, causing the chicken wing root to swing in the width direction, causing the chicken wing root to detach from the second clamp and affecting subsequent transmission. Summary of the Invention

[0012] In order to solve the above problems, this invention proposes a special processing device for chicken wing roots, which aims to solve the technical problems of deviation and derailment.

[0013] According to some embodiments, the present invention adopts the following technical solution:

[0014] This application discloses a special processing device for chicken wing roots, comprising: a machine tool and a pair of chain plate conveyor belts mounted on the machine tool, wherein storage grooves are provided on both sides of the chain plate conveyor belts, and a cutting mechanism is installed above the chain plate conveyor belts.

[0015] Several wing root clamping plate groups are fixedly arranged at intervals along the conveying direction on the conveyor belt. Each wing root clamping plate group consists of a first clamping plate and a second clamping plate arranged opposite to each other, and a third clamping plate is arranged between the first clamping plate and the second clamping plate.

[0016] The cutting mechanism consists of a combined blade holder and a telescopic drive unit for driving the combined blade holder to move up and down. Limiting plates are fixedly installed on both sides of the combined blade holder. The telescopic drive unit is installed with a first fixed frame on one side. The fixed frame has an installation groove for placing the combined blade holder. A limiting groove is opened through the side wall of the installation groove. The limiting plate is movably installed in the limiting groove.

[0017] The combined blade holder is equipped with a cutter for simultaneously cutting the chicken meat on both sides of the wing root internal bone and a spring pressure plate for pressing down the small bone end of the wing root. The cutter consists of two blades arranged opposite each other on both sides of the combined blade holder; along the conveying direction, the spring pressure plate is located in front of the cutter.

[0018] Further configured, the telescopic drive unit is provided with a first fixed frame, the first fixed frame has an installation slot for placing the combined tool holder, the side wall of the installation slot has a limiting slot through it, the combined tool holder is composed of a vertical section and a horizontal section, and a limiting plate for inserting into the limiting slot is fixedly installed on both sides of the vertical section.

[0019] A further configuration is that the horizontal section is fixedly connected to the telescopic part of the telescopic unit, the cutter is detachably mounted on the horizontal section, and the spring pressure plate is hinged to the horizontal section.

[0020] Further configured, the spring pressure plate consists of a pressure plate and a spring connecting shaft. One end of the pressure plate is hinged to the horizontal section, the spring connecting shaft is vertically arranged, the bottom end of the spring connecting shaft is fixedly connected to the pressure plate, and the upper end of the spring connecting shaft is movably connected to a second fixed frame fixedly installed on the vertical section.

[0021] Further configured, the spring connecting shaft consists of a connecting shaft and a spring sleeved on the connecting shaft, and the second fixing bracket has a mounting hole for mounting the connecting shaft, with the top end of the connecting shaft passing through the mounting hole and threaded with a nut.

[0022] Further configured, the mounting hole is a long, narrow hole structure.

[0023] Further configured, the first fixed frame telescopic drive unit is fixedly installed inside the cover of the machine tool, and the cover is fixedly installed on the machine tool.

[0024] Further configured such that all the wing root clamp assemblies are on the same straight line.

[0025] Further configured, the first clamp is located in front of the second clamp, the first clamp is used to place the small bone end of the wing root, the second clamp is used to place the large bone end of the wing root, and the third clamp is used to place the leg meat of the wing root.

[0026] Further configured, the machine tool is also equipped with a sensing mechanism, which consists of a sensing switch fixedly installed on the machine tool and sensing points fixedly installed on the conveying mechanism. The sensing switch is connected to the telescopic drive unit, and the sensing points correspond one-to-one with the wing root clamping plate group.

[0027] Secondly, the present invention provides a method for processing wing roots, as detailed below:

[0028] Place one wing root in each wing root clamping plate group, so that the small bone end of the wing root is inserted into the first clamping plate, the large bone end of the wing root is inserted into the second clamping plate, and the leg meat is inserted into the third clamping plate.

[0029] When a wing root is detected to have moved directly under the cutting mechanism, the telescopic drive unit drives the combined blade holder to move downward, so that the pressure plate presses against the small bone end of the wing root, and the two blades are inserted into the chicken meat on both sides of the wing root's internal bone at the same time.

[0030] The position of the cutter remains unchanged, and the wing root with the blade inserted moves with the conveyor mechanism. The wing root continues to be cut until it reaches the end of the large bone. The cutter and the spring pressure plate move upward in sync, completing the cutting of the chicken meat on both sides of the inner bone of a wing root.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] (1) The existing limiting ring is optimized into a slot made of two steel plates. There is a gap of a fixed size in the middle of the slot. The fixed plates on both sides of the tool holder slider can move up and down in this gap. Even if the tool is resisted during the cutting process, the fixed plate is restricted in the slot. The fixed plate can only complete the vertical position, and the tool will not be displaced in the new direction of the conveyor belt.

[0033] (2) The original single-chain cutting production line was upgraded to a double-chain cutting production line. Storage tanks were added to both sides of the moving chain. The placement and size of the tanks were determined by factors such as the range of motion of the employees and their work habits. The processing personnel directly picked up the materials from the storage tanks and poured the materials into the storage tanks before processing, which reduced the frequency of raw material transfer.

[0034] (3) The positioning device is divided into a first clamp corresponding to the large bone end, a second clamp corresponding to the leg meat, and a third clamp corresponding to the small bone end. The large bone end, small bone end and leg meat of the wing root are respectively clamped in the corresponding clamp to fix the length and width of the wing root and prevent deviation during the cutting process.

Detailed implementation method:

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0046] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0047] Example 1

[0048] like Figure 1 As shown, a special processing device for chicken wing roots includes: a machine tool 1 and a pair of chain plate conveyor belts 2 installed on the machine tool 1. Storage troughs 14 are opened on both sides of the chain plate conveyor belts 2. A cutting mechanism is installed above the chain plate conveyor belts 2. Processing personnel can directly put the materials into the storage troughs 14, which can reduce the frequency of raw material transfer. The placement position and size can be determined based on factors such as the range of motion of employees, working habits, and ease of operation. Employees face the chain plate conveyor belts 2 and do not need to turn around or bend over, reducing the workload of employees.

[0049] Each chain plate conveyor belt 2 is fixedly provided with several wing root clamping plate groups 16 at intervals along its conveying direction. All the wing root clamping plate groups 16 are on the same straight line and are mainly used for positioning chicken wing roots on the chain plate conveyor belt 2 to facilitate the positioning and cutting of wing roots.

[0050] like Figure 2 As shown, the cutting mechanism consists of a combined blade holder 3 and a telescopic drive unit 5 for driving the combined blade holder 3 to move up and down. Limiting plates 31 are fixedly installed on both sides of the combined blade holder 3. The telescopic drive unit 5 is installed with a first fixed frame 4 on one side. The fixed frame has an installation groove 41 for placing the combined blade holder 3. A limiting groove 42 is opened through the side wall of the installation groove 41. The limiting plate 31 is movably installed in the limiting groove 42. The width of the limiting groove 42 is slightly larger than the thickness of the limiting plate 31, so that the limiting plate 31 can only be displaced in the vertical direction in the limiting groove 42. The slight displacement in the horizontal direction (the traveling direction of the chain plate conveyor belt 2) will not affect the subsequent cutting effect.

[0051] like Figure 3 and Figure 4As shown, the combined knife holder 3 is equipped with a cutting blade 6 for simultaneously cutting the chicken meat on both sides of the wing root's internal bone and a spring pressure plate 7 for pressing down on the small bone end of the wing root. The cutting blade 6 consists of two blades arranged opposite each other on both sides of the combined knife holder 3. Along the conveying direction, the spring pressure plate 7 is located in front of the cutting blade 6, that is, the spring pressure plate is located at the front end of the conveying direction relative to the cutting blade 6 (or it can be understood that in the conveying direction, the spring pressure plate is located in front of the cutting blade), and the cutting blade 6 is located behind the spring pressure plate. Thus, after the combined knife holder 3 is lowered, the tip of the cutting blade 6 is inserted into the initial cutting position, and the spring pressure plate presses down on the small bone end of the wing root. As the wing root moves with the chain plate conveyor belt 2, the cutting blade 6 cuts the wing root. At the same time, the spring pressure plate presses down on the small bone end of the wing root to prevent the small bone end of the wing root from lifting up.

[0052] like Figure 2 As shown, the telescopic drive unit 5 is provided with a first fixed frame 4. The first fixed frame 4 has an installation slot 41 for placing the combined tool holder 3. A limiting slot 42 is provided through the side wall of the installation slot 41. The combined tool holder 3 is composed of a vertical section and a horizontal section. A limiting plate 31 for inserting into the limiting slot 42 is fixedly installed on both sides of the vertical section.

[0053] In this embodiment, the telescopic drive unit 5 is a telescopic cylinder. The bottom of the piston rod of the telescopic cylinder is detachably connected to the horizontal section of the combined tool holder 3 by bolt connection, which can adjust the initial position height of the combined tool holder 3 as needed.

[0054] The horizontal section is fixedly connected to the telescopic part of the telescopic unit, the cutter 6 is detachably installed on the horizontal section, and the spring pressure plate 7 is hinged on the horizontal section.

[0055] The spring pressure plate 7 consists of a pressure plate and a connecting shaft 9. One end of the pressure plate is hinged to the horizontal section, and the connecting shaft 9 is set vertically. The bottom end of the connecting shaft 9 is fixedly connected to the pressure plate, and the upper end of the connecting shaft 9 is movably connected to the second fixed frame 8 fixedly installed on the vertical section.

[0056] The connecting shaft 9 consists of a connecting shaft 9 and a spring 10 sleeved on the connecting shaft 9. The second fixing bracket 8 has a mounting hole for mounting the connecting shaft 9. The top end of the connecting shaft 9 passes through the mounting hole and is threaded with a nut. The mounting hole is an elongated hole structure. The bottom end of the connecting shaft 9 is fixedly connected to the pressure plate.

[0057] The first fixed frame 4 and the telescopic drive unit 5 are fixedly installed inside the cover 13 on the machine tool 1. The cover 13 is fixedly installed on the machine tool 1. The combined tool post 3 is movably set on the first fixed frame 4. The combined tool post 3 is fixedly connected to the telescopic part of the telescopic drive unit 5, so that the combined tool post 3 can be controlled to move up and down along the first fixed frame 4 under the action of the telescopic drive unit 5. The cutting blade 6 and the spring pressure plate are installed on the combined tool post 3 and can move synchronously with the combined tool post 3.

[0058] Understandably, in order to facilitate observation of the cutting process, the cover 13 can be made into a transparent structure in actual use.

[0059] All the wing root clamping plate assemblies are on the same straight line. Each wing root clamping plate assembly consists of a first clamping plate 11 and a second clamping plate 12 arranged opposite to each other. The first clamping plate 11 and the second clamping plate 12 are both U-shaped structures, and the side of the second clamping plate 12 away from the first clamping plate 11 is closed.

[0060] The first clamping plate 11 is located at the front end of the conveying direction of the chain plate conveyor belt 2, and the second clamping plate 12 is located at the rear end of the conveying direction of the chain plate conveyor belt 2. That is, along the conveying direction, the first clamping plate 11 is located in front of the second clamping plate 12, and a third clamping plate 15 is provided between the first clamping plate 11 and the second clamping plate 12. Each part of the chicken wing root is inserted into the first clamping plate 11, the second clamping plate 12 and the third clamping plate 15 respectively.

[0061] Among them, the first clamping plate 11, the second clamping plate 12 and the third clamping plate 15 are metal sheets set on the conveyor chain plate. The metal sheets have a certain elasticity. After the chicken wing root is inserted, the first clamping plate 11, the second clamping plate 12 and the third clamping plate 15 are pushed outward, and then the chicken wing root is tightened under the action of elasticity.

[0062] It is understandable that the spacing between adjacent first clamping plates 11, second clamping plates 12 and third clamping plates 15, as well as between adjacent sets of wing root clamping plates, can be determined according to actual design requirements, and no further restrictions are imposed here.

[0063] The machine tool 1 is also equipped with a sensing mechanism, which consists of a sensing switch fixedly installed on the machine tool 1 and sensing points fixedly installed on the conveying mechanism. The sensing switch is connected to the telescopic drive unit 5, and the sensing points are sensing metal plates 17. The sensing points are fixedly installed on the upper chain plate conveyor belt 2. The sensing points correspond one-to-one with the wing root clamping plate group and are used to detect the position of the first clamping plate 11 and the second clamping plate 12 in the same group, thereby detecting the position of the wing root, which facilitates the control of the lifting and lowering of the cutter 6 and the spring pressure plate to automatically complete the double-sided synchronous cutting of the wing root.

[0064] Example 2

[0065] In another typical embodiment of the present invention, a method for processing wing roots is proposed, utilizing the wing root-specific processing device described in Example 1. The specific processing flow is as follows:

[0066] The processing personnel are divided into two groups and stand on both sides of the two storage tanks 14. They directly feed the materials into the storage tanks 14 and manually pick up the wing roots from the storage tanks 14 and place them on the chain plate conveyor belt 2. One wing root is placed in each wing root clamping plate group, so that the small bone end of the wing root is located at the first clamping plate 11, the large bone end of the wing root is located at the second clamping plate 12, and the leg meat part of the wing root is located at the third clamping plate 15.

[0067] The wing root moves along the chain plate conveyor belt 2. When the sensing mechanism detects that a wing root has moved directly below the cutting mechanism, it controls the telescopic drive unit 5 to extend downward. The combined blade holder 3 drives the cutter 6 and the spring pressure plate 7 to move downward, so that the spring pressure plate 7 presses the small bone end of the wing root to prevent the small bone end from tilting upward. The two blades are inserted into the chicken meat on both sides of the wing root's internal bone at the same time.

[0068] This ensures that the limiting plate 31 can only move significantly in the vertical direction within the limiting groove 42, while the slight deviation in the horizontal direction (the traveling direction of the chain plate conveyor belt 2) will not affect the subsequent cutting effect.

[0069] Understandably, the distance between the blade insertion point and the small bone end can be adjusted according to actual needs, and no further restrictions are imposed here.

[0070] The wing root with blades moves along the chain plate conveyor belt 2. During the movement of the wing root, the position of the cutter 6 remains unchanged. As the chain plate conveyor belt 2 rotates, the cut on the wing root continues to be cut until it reaches the end of the large bone. The telescopic drive unit 5 moves upward, and the cutter 6 and the spring pressure plate move upward synchronously to complete the cutting of the chicken meat on both sides of the inner bone of a wing root.

[0071] Repeat the above steps until all the fins on the chain plate conveyor belt 2 have been processed.

[0072] Among them, the spring pressure plate 7 can keep the wing root pressed at all times under the action of the spring connecting shaft, preventing the wing root from lifting or shifting, and can adapt to wing roots of different thicknesses; the blade does not come into contact with the surface of the chain plate conveyor belt 2 during the cutting process, so as to avoid the muscle being completely cut off.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0074] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
