Description

Technical Field

[0001] This invention relates to the technical field of chicken feet processing, specifically to a fully automatic toenail removal device for chicken feet processing. Background Technology

[0002] In the industrial processing of tiger-skin chicken feet and related chicken feet snack foods, the crevices of chicken feet toenails easily trap mud, dirt, and bacteria, which are difficult to clean thoroughly by conventional washing alone, directly affecting the hygiene quality and food safety of the finished product; therefore, the toenails must be completely removed during the pre-processing stage of chicken feet raw materials, which is an indispensable process for the deep processing of chicken feet.

[0003] Currently, the industry mainly uses two methods for removing chicken feet nails. The first is manual trimming, where workers manually trim the nails one by one with scissors. This method has extremely low processing efficiency, high labor costs, and high labor intensity, making it unsuitable for large-scale assembly line production. At the same time, the lack of standardized manual operation can easily lead to problems such as trimming residue, uneven cutting, and damage to the nail, making it difficult to guarantee product consistency and yield. The second method is semi-automatic nail removal equipment. Although it achieves automated driving of the cutting blades, workers still need to hold the chicken feet throughout the operation, feeding the nails one by one into the cutting blades. The operators' hands are in close contact with the high-speed moving cutting structure for a long time, posing serious safety hazards such as pinching injuries and accidental cutting injuries. Moreover, this type of equipment still requires dedicated personnel to operate, so the labor demand is not reduced, and it cannot truly achieve cost reduction and efficiency improvement.

[0004] Therefore, there is a need for a fully automated toenail removal device for chicken feet processing to solve the problems raised in the background technology. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a fully automatic toenail removal device for chicken feet processing, which solves the problems of low efficiency and poor consistency of manual trimming, and safety hazards and high dependence on manual labor in semi-automatic equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic toenail removal device for chicken feet processing, comprising a chicken feet conveyor belt, on one side of which a clamping structure, a toenail removal device, and a chicken feet receiving belt are sequentially arranged according to the working steps; the chicken feet conveyor belt is used to transport chicken feet to be processed, the clamping structure is provided with a clamping arm, which can clamp the chicken feet to be processed on the chicken feet conveyor belt onto the toenail removal device for toenail removal processing; the toenail removal device includes a chicken feet placement tray for placing and fixing chicken feet, and a toenail removal blade for cutting off toenails, the clamping arm can clamp the chicken feet that have undergone toenail removal processing onto the chicken feet receiving belt; the chicken feet receiving belt is provided with a detection structure, which includes an electric push rod, which can push chicken feet that have failed to pass the toenail removal process onto the receiving belt into a collection box. Preferably, the clamping structure further includes a rotating disk, which is driven to rotate by an external motor. Multiple transmission screws are provided on the lower side of the rotating disk, and the transmission screws drive the clamping arm to move horizontally.

[0007] Preferably, the toe removal device includes a work frame with a sliding groove. A chicken claw placement tray is slidably connected inside the sliding groove. At least four fixed frames are installed on the work frame. Each fixed frame has a toenail hole and a toenail removal knife is slidably connected inside the fixed frame. A cylinder is installed on the work frame, and the cylinder can drive the toenail removal knife to slide inside the fixed frame.

[0008] Preferably, a waste drawer is slidably connected inside the work frame, the fixed frame is in communication with the waste drawer, and a detachable screen is installed inside the waste drawer.

[0009] Preferably, a flattening structure is provided on one side of the fixed frame. The flattening structure includes a movable cylinder, and a movable air plug is slidably connected inside the movable cylinder. The piston rod of the movable air plug is fixedly connected to the driving end of the cylinder through a connector to achieve synchronous reciprocating motion. A plug-in pipe is fixedly connected inside the work frame. A plug-in hole is provided on the waste drawer. The plug-in pipe and the plug-in hole are mating components. An air blowing chamber is provided between the movable cylinder and the plug-in pipe. A one-way valve is installed on both the movable cylinder and the air blowing chamber. Multiple flattening air holes are provided on the waste drawer. The flattening air holes blow air horizontally onto the waste drawer.

[0010] Preferably, a water-holding pipe is installed on one side of the movable cylinder, and an expansion chamber is provided inside the water-holding pipe. A membrane is installed on the expansion chamber. One-way water inlet pipe and one-way water outlet pipe are respectively provided on the upper and lower sides of the water-holding pipe. The one-way water inlet pipe is connected to an external water source. Multiple nozzles are installed inside the working frame. The nozzles are connected to the one-way water outlet pipe. An air-filling pipe is fixedly connected to the expansion chamber and the movable cylinder.

[0011] Preferably, the lower side of the chicken feet placement tray is provided with a reinforcing structure, which includes a sliding frame that slides inside the sliding groove. The sliding frame has a working chamber and an exhaust chamber inside. A gear set is rotatably connected inside the working chamber, and a first magnet is installed on the gear set. A sliding plug is vertically slidably connected inside the exhaust chamber, and a second magnet is fixedly connected to the upper side of the sliding plug. Four sets of clamping plates are fixedly connected to the chicken feet placement tray, and airbags are installed on the clamping plates. The airbags communicate with the exhaust chambers. A toothed plate is installed inside the sliding groove, and the toothed plate meshes with the gear set. The length of the toothed plate allows the first magnet to rotate 180°, so that the first magnet and the second magnet are in a repulsive state, thereby driving the sliding plug to compress into the exhaust chamber, inflating the airbag to clamp the chicken feet. When the chicken feet placement tray is in the initial position, the first magnet and the second magnet are in an attractive state.

[0012] Preferably, a pressure sensor is provided at the connection between the cylinder and the descaling blade, and the pressure sensor records the force signal applied by the cylinder to the descaling blade each time.

[0013] Preferably, the electric push rod is installed on one side of the chicken claw receiving belt, and a push port is opened on the other side of the chicken claw receiving belt. A material holding box is provided below the push port. A detection camera is installed above the chicken claw receiving belt. The detection camera is electrically connected to the electric push rod. Symmetrical guide rods are installed on the chicken claw receiving belt.

[0014] Preferably, the clamping arm first clamps the chicken feet on the upper side of the chicken feet conveyor belt. Then, the rotating disk rotates, and the clamping arm places the chicken feet to be processed into the chicken feet placement tray. Next, the transmission screw drives the clamping arm to move towards the chicken feet placement tray, and the clamping arm contacts the chicken feet placement tray and applies a pushing force, causing the chicken feet placement tray to slide along the sliding groove to the working position. After the toenail removal is completed, the transmission screw drives the clamping arm to pull the chicken feet placement tray back to the initial position. The rotating disk drives the clamping arm to rotate and switch positions between the chicken feet conveyor belt, the toenail removal device, and the chicken feet receiving belt.

[0015] This invention provides a fully automated toenail removal device for chicken feet processing. It has the following beneficial effects: 1. This invention, through the linkage between the clamping structure and the de-toeing device, automates the entire process from feeding chicken feet, recognizing the shape of chicken feet, grasping chicken feet, placing chicken feet to cutting and unloading. The operator's hands do not need to touch the cutting blades throughout the process, fundamentally eliminating safety accidents such as pinching injuries and accidental cutting injuries. Only one person is needed to be responsible for replenishing raw materials and cleaning up waste, which greatly reduces labor costs.

[0016] 2. This invention features a chicken claw placement tray that accurately places the toenails inside the toenail hole of the fixing frame, facilitating the removal of the toenails by the nail remover. The reinforcement structure uses the magnetic force generated between magnets and the linkage principle of airbags to clamp the chicken claws, ensuring that each chicken claw is fixed in a fixed state during toenail removal, preventing additional damage to the chicken claws during removal.

[0017] 3. The flattening structure of the present invention uses a cylinder as a shared power source for the nail remover and the flattening air hole. This structure does not require an additional power device. The pulsed airflow generated by the flattening air hole blows intermittently onto the freshly fallen nail waste, breaking it up and flattening it, preventing the soft, wet nail fragments from accumulating in one place or sticking to the box wall. This setting ensures the storage space of the waste drawer, thereby enabling the waste drawer to hold more nail fertilizer. Attached Figure Description

[0019] The technical solutions in 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 some embodiments of the present invention, and not all embodiments. 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.

[0020] Please see the appendix Figure 1 - Appendix Figure 8 This invention provides a fully automatic toenail removal device for chicken feet processing. The device adopts a rotary multi-station layout and mainly includes a chicken feet conveyor belt 1, a clamping structure 2, a toenail removal device 3, and a chicken feet receiving belt 4. The above devices are arranged in sequence according to the processing steps.

[0021] like Figure 1 As shown, the chicken claw conveyor belt 1 is responsible for conveying the chicken claws to be processed forward. At the end of the conveyor belt, i.e., the clamping structure 2, there is a vision recognition component consisting of a photoelectric sensor and an industrial camera. When the chicken claw is conveyed to the designated position, the photoelectric sensor first detects the material arrival signal and triggers the industrial camera to take a quick picture of the chicken claw. The vision system identifies the orientation and position of the chicken claw through the image recognition algorithm, and then transmits the grasping coordinates and posture data to the control system. The control system determines whether the chicken claw is in a graspable posture based on the recognition result. If the position of the chicken claw is too far off, a signal is sent for the chicken claw conveyor belt 1 to start and stop briefly to assist the chicken claw in adjusting its position until it is easy for the clamping arm 203 to grasp.

[0022] like Figure 3 As shown, the clamping structure 2 consists of a rotating disk 201, a transmission screw 202, and clamping arms 203. The rotating disk 201 is mounted on the top of the frame and is driven by a servo motor, which can rotate the rotating disk 201. Each clamping arm 203 is equipped with a pneumatic gripper at its end. The pneumatic gripper uses arc-shaped grippers covered with food-grade silicone. The pneumatic grippers can provide sufficient clamping friction without damaging the skin of the chicken feet. The clamping structure 2 in this embodiment is provided with four sets of clamping arms 203. The four sets of clamping arms 203 correspond to the chicken feet conveyor belt 1, the toe removal device 3, the chicken feet receiving belt 4, and the standby position, respectively. Each set of clamping arms 203 is equipped with a lifting cylinder to facilitate the up and down movement of the clamping arm 203.

[0023] The above-mentioned equipment operates in the following steps: like Figure 3 and 4 As shown, in step one: after the vision system confirms the position of the chicken claw and meets the grasping requirements, the control system sends the grasping coordinates to the clamping structure 2. At this time, the clamping arm 203 is already located above the chicken claw conveyor belt 1. The clamping arm 203 extends downward to allow the pneumatic gripper to grasp the chicken claw. Then the clamping arm 203 retracts to complete the material handling.

[0024] Specifically, if the position of the chicken feet on the chicken feet conveyor belt 1 is relatively far off, a guide rod 702, which is the same as the chicken feet receiving belt 4, can be installed on the chicken feet conveyor belt 1 to guide the movement of the chicken feet and keep them in the middle position of the chicken feet conveyor belt 1.

[0025] Furthermore, a device for sorting chicken feet can be added to the front end of the conveyor belt; a soft roller with a soft brush is placed on the conveyor belt and rotated in the opposite direction to the direction from which the chicken feet come. When a pile of chicken feet is transported through the chicken foot conveyor belt 1, the brush will scrape the stacked chicken feet, allowing only the bottom single layer of chicken feet to pass through one by one. This ensures that the chicken feet to be photographed and grabbed later are all laid out separately.

[0026] like Figure 3 and 4 As shown, in step two: after the material is picked up, the rotating disk 201 rotates under the drive of the servo motor, transferring the gripping arm 203 and the chicken feet it grips to the top of the toe removal device 3; at this time, the gripping arm 203 is exactly above the chicken feet placement disk 303, and the chicken feet placement disk 303 is in its initial position.

[0027] During the descent, the clamping arm 203 falls onto the chicken feet placement tray 303, with the chicken feet positioned between the four sets of clamping plates 3031 of the chicken feet placement tray 303. At this time, the clamping arm 203 applies pressure to the chicken feet placement tray 303, while the lead screw applies a thrust. Under the continuous pressure and thrust, the chicken feet placement tray 303 is pushed forward along the sliding groove 302, moving from the initial position to the working position. The four toes of the chicken feet are inserted into the nail holes of the fixing frame 304, facilitating subsequent removal.

[0028] like Figure 4 and 7 As shown, in step three: during the sliding process of the chicken feet placement tray 303 from the initial position to the working position, the reinforced structure 6 also begins to work; when the sliding frame 601 moves together with the chicken feet placement tray 303, the gear set 604 in the working cavity 602 meshes with the toothed plate in the sliding groove 302, and the gear set 604 drives the first magnet 605 to rotate. The length of the toothed plate is designed so that when the gear set 604 rotates, the first magnet 605 completes a 180° rotation. At this time, the first magnet 605 and the second Magnet 606 changes from an attractive state to a repulsive state. Under the action of the repulsive force, the sliding plug 607 slides upward, compressing the air in the exhaust chamber 603. The gas enters the air bladder 3032 on the clamping plate 3031. The air bladder 3032 expands rapidly under the action of air pressure, clamping the toe root of the chicken foot, fixing the position of the toe root of the chicken foot, and preventing the chicken foot from separating due to the movement of the chicken foot placement plate 303. It also makes a fine adjustment to the position of the toe root so that it can be aligned with the toenail hole of the fixing bracket 304.

[0029] like Figure 6 and Figure 8 As shown, in step four: after the chicken claw toenail is inserted into the toenail hole, the control system sends an action command to the cylinder 306. The piston rod of the cylinder 306 extends, driving the four nail-removing blades 305 to slide synchronously on the fixed frame 304. The nail-removing blades 305 remove the toenail that has passed through the toenail hole. The removed toenail waste falls naturally into the waste drawer 307 below the fixed frame 304 under the action of gravity. After the removal is completed, the piston rod of the cylinder 306 retracts, driving the nail-removing blades 305 back to their initial position. The cutting edge of the nail-removing blade 305 adopts an arc-shaped concave blade design, so that the curvature of the nail-removing blade is the same as that of the chicken claw toenail. The remaining length of the toenail is controlled within 0.5mm. The nail-removing blade 305 is made of food-grade 440C stainless steel and can continuously process more than 80,000 chicken claws.

[0030] Furthermore, when cylinder 306 applies force to the descaling blade 305, it applies force to pressure sensor 308. Pressure sensor 308 records the force applied by cylinder 306 to descaling blade 305. When descaling blade 305 becomes dull, the reaction force generated by descaling blade 305 is transmitted to cylinder 306. The pressure applied by cylinder 306 to descaling blade 305 will increase on pressure sensor 308. Therefore, based on the value recorded by pressure sensor 308, it can be determined whether descaling blade 305 has become dull, so that it can be replaced in time.

[0031] During the synchronous operation of the shearing action of the cylinder 306, the leveling structure 5 also works. Since the piston rod of the movable air plug 502 is connected to the cylinder 306, each reciprocating motion of the cylinder 306 simultaneously drives the movable air plug 502 to reciprocate in the movable cylinder 501. Through the cooperation of the movable cylinder 501 and the two one-way valves 503 on the air blowing chamber 504, a pulsed airflow is formed in the air blowing chamber 504. This airflow enters the waste drawer 307 through the insertion pipe 505 and the insertion hole 3071, and is horizontally ejected from multiple leveling air holes 3072. The pulsed airflow can intermittently blow onto the toenail waste that has just fallen, breaking up and flattening the toenail stacked inside the waste drawer 307, preventing the accumulation or adhesion of wet and soft toenail fragments to the box wall, so that the waste drawer 307 can store more toenail.

[0032] Furthermore, when the movable air plug 502 moves downward, a portion of the gas in the movable cylinder 501 enters the expansion chamber 512, causing the membrane 511 inside the expansion chamber 512 to expand. When the membrane 511 expands, it increases the internal pressure of the water pipe 507, causing water inside the water pipe 507 to enter the nozzle 510 and then be sprayed from the nozzle 510 onto the inner wall of the waste drawer 307 to wash the toenails on the waste drawer 307, remove bloodstains and viscous substances from the toenails, slow down the adhesion of the toenails, and the screen 3073 can separate the toenails from the blood.

[0033] When the movable air plug 502 moves upward, the membrane 511, under its own elasticity and with the reduced pressure applied by the movable cylinder 501, causes the pressure inside the expansion chamber 512 to decrease. The gas inside the expansion chamber 512 returns to the movable cylinder 501 through the air supply pipe 506. At this time, the membrane 511 contracts in the opposite direction, causing the water-holding pipe 507 to be in a negative pressure state. Then, external water can be drawn in through the one-way water inlet pipe 508, so that the water-holding pipe 507 is in a water-filled state, which is convenient for the next flushing.

[0034] like Figure 2 and 4As shown, in step five: when the cylinder 306 and the nail remover 305 return to their initial positions, the transmission screw 202 drives the clamping arm 203 to return to its initial position. During the process of returning to the initial position, the clamping arm 203 still grips the chicken feet with the nails removed. During this process, under the action of the clamping arm 203 and the screw, the chicken feet placement tray 303 is driven to slide in the opposite direction along the sliding groove 302, so that the chicken feet placement tray 303 also returns to its initial position.

[0035] As the chicken feet placement tray 303 returns to its initial position, the gear set 604 rotates in the opposite direction as the chicken feet placement tray 303 retracts. The first magnet 605 rotates 180°, which is the initial angle. The first magnet 605 and the second magnet 606 are in a state of attraction again. The sliding plug 607 resets under the action of magnetic attraction. The gas in the airbag 3032 returns to the exhaust chamber 603. The airbag contracts, and the chicken feet are no longer clamped. At this time, the clamping arm 203 removes the chicken feet from the chicken feet placement tray 303.

[0036] Furthermore, a miniature pressure relief valve is provided between the exhaust chamber 603 and the airbag 3032, which can automatically release pressure when the pressure inside the airbag is too high, preventing the airbag from rupturing due to excessive pressure.

[0037] Step Six: After the clamping arm 203 lifts the de-nails-removed chicken feet from the chicken feet placement tray 303, the rotating tray 201 starts again, causing the clamping arm 203 to rotate above the chicken feet collection belt 4. The clamps open, and the de-nails-removed chicken feet fall onto the chicken feet collection belt 4. A washing pool can be set at the end of the chicken feet collection belt 4, and the chicken feet on the chicken feet collection belt 4 can fall into the washing pool for cleaning.

[0038] Specifically, when the chicken feet receiving belt 4 moves the chicken feet, the detection camera 703 will take pictures and detect them, and the image of the chicken feet will be acquired. When the detection camera 703 determines that the chicken feet are unqualified, the controller drives the electric push rod 701 to extend and drop the chicken feet from the push port 704 into the holding box 705. The qualified chicken feet will continue to be sent out with the chicken feet receiving belt 4 to the next process.

[0039] Furthermore, the chicken feet receiving belt 4 is also equipped with a guide rod 702. The guide rod 702 ensures that the chicken feet on the chicken feet receiving belt 4 are always in the middle position of the receiving belt, which is convenient for the detection camera 703 to take pictures.

[0040] All the components of the above-mentioned equipment that come into direct contact with chicken feet, including the gripper of the gripping arm 203, the chicken feet placement tray 303, the gripping plate 3031, the airbag 3032, the nail remover 305, the fixing frame 304, and the waste drawer 307, are made of food-grade 304 stainless steel or food-grade silicone rubber, which comply with national food safety standards and meet the requirements of food processing workshops.

[0041] Example 2: like Figure 8 As shown, the other structures in this embodiment are the same as in Embodiment 1; the only difference is that the air supply pipe 506 is connected to the upper side of the movable cylinder 501 and the upper side of the movable air plug 502. When the movable air plug 502 moves down, the expansion chamber 512 is in a negative pressure state. At this time, the membrane 511 contracts in the opposite direction, that is, the water-holding pipe 507 completes the water absorption process. Conversely, when the movable air plug 502 moves up, the gas inside the movable cylinder 501 enters the expansion chamber 512. At this time, the membrane 511 expands and applies pressure to the water-holding pipe 507, causing the water inside the water-holding pipe 507 to be sprayed out.

[0042] Based on the above technical solution, this embodiment of the invention also provides a working principle of a fully automatic toenail removal device for chicken feet processing, including the following: The chicken feet to be processed are conveyed to the end by the chicken feet conveyor belt 1. The control system controls the clamping arm 203 to extend downwards, using pneumatic grippers to grab the chicken feet and then retract. The rotating disk 201 rotates under the drive of a servo motor, transferring the clamping arm 203 along with the chicken feet to the top of the toenail removal device 3. The clamping arm 203 extends downwards again to place the chicken feet into the chicken feet placement tray 303 in its initial position. Subsequently, the transmission screw 202 drives the clamping arm 203 to move, clamping... The side of the holding arm 203 contacts the end of the chicken claw placement tray 303 and applies a pushing force, pushing the chicken claw placement tray 303 to slide along the sliding groove 302 from its initial position into the toenail hole of the fixing frame 304; during the sliding of the chicken claw placement tray 303, the reinforcing structure 6 below it also works simultaneously; the gear set 604 in the sliding frame 601 rotates with the sliding groove 302, driving the first magnet 605 to rotate, causing its polarity to change from attraction to repulsion with the second magnet 606; this repulsive force pushes the sliding plug 607 upward, compressing the gas in the exhaust chamber 603, and the gas enters When the airbag 3032 inflates and clamps the toe base, securing the chicken claw, the cylinder 306 drives four nail removers 305 to slide synchronously within the mounting bracket 304, cutting off the toenail. The toenail waste falls into the waste drawer 307. Simultaneously with the operation of the cylinder 306, the movable air plug 502 is driven to reciprocate within the movable cylinder 501 via the connecting piece. This creates a pulsed airflow within the blowing chamber 504 through the cooperation of two one-way valves 503, which is then horizontally ejected from the leveling air hole 3072, breaking up and flattening the waste. When the transmission screw 202 drives the clamping arm 203 to return to its initial position, it causes the chicken claw to be placed... The disc 303 returns to its initial position, the gear set 604 rotates in the opposite direction to return the first magnet 605 to its initial position, and the airbag 3032 retracts; the clamping arm 203 lifts the finished chicken feet, the rotating disc 201 rotates to send them to the top of the chicken feet receiving belt 4 and releases them; when the chicken feet receiving belt 4 moves with the chicken feet, the detection camera 703 takes pictures and processes them, and captures images of the four toe ends of the chicken feet; when unqualified chicken feet are detected, the push rod 701 extends and pushes the chicken feet into the holding box 705; qualified chicken feet continue to move, completing the overall work process.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
