Description

[0001] This application is a divisional application of application number 201811259050.6, filed on October 26, 2018, entitled "An Automatic Duck Gizzard Opening, Cleaning and Grinding Production Device". Technical Field

[0002] This invention relates to a duck gizzard processing equipment, and more particularly to an automatic duck gizzard opening, cleaning and grinding production device. Background Technology

[0003] Currently, the automatic cutting, cleaning, and skin-removing processes for duck gizzards are all completed manually by semi-automatic equipment in slaughterhouses. Some manufacturers use semi-automatic cleaning and skin-removing equipment, requiring manual placement of the duck gizzards into the cleaning equipment, which uses a spiral water trough. Skin removal is also done manually by pressing the duck gizzards onto the grinding wheels on the equipment. Each slaughter line requires 4 workers for cutting duck gizzards and 4 workers for skin removal, totaling 8 people. This results in low production efficiency and increasingly high labor costs. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a production device for automatically opening, cleaning and grinding duck gizzards, which is basically fully automated.

[0005] To achieve the above objectives, the present invention proposes the following technical solution: an automatic duck gizzard opening, cleaning, and grinding production device, comprising an electrical control system, and a gizzard opening mechanism, a cleaning mechanism, and a gizzard grinding mechanism, all connected to the electrical control system and sequentially connected to each other, wherein...

[0006] The gizzard opening mechanism includes a gizzard opening frame and a conveying mechanism, a robotic gripper, a height sensor, and a cutting mechanism mounted on the gizzard opening frame. The robotic gripper is mounted on the conveying mechanism and, driven by the conveying mechanism, carries the duck gizzard past the location of the height sensor and reaches below the cutting mechanism. The cutting mechanism descends to the corresponding height according to the height signal from the height sensor to cut the duck gizzard open.

[0007] The cleaning mechanism includes a cleaning frame and a duck gizzard support shaft, a set of duck gizzard pushing mechanisms and a roller brush mechanism, all mounted on the cleaning frame. The duck gizzard support shaft is located between the duck gizzard pushing mechanisms and is used to support the cut duck gizzard. The duck gizzard pushing mechanisms push the duck gizzards on the duck gizzard support shaft to the roller brush mechanism to clean the debris inside the duck gizzard.

[0008] The gizzard grinding mechanism includes a gizzard grinding frame and a turntable mechanism and a gizzard grinding wheel mechanism mounted on the gizzard grinding frame. The turntable mechanism includes multiple gizzard grooves for placing cleaned duck gizzards. The turntable mechanism drives the duck gizzards in the gizzard grooves to the gizzard grinding wheel mechanism to grind off the yellow skin of the duck gizzards.

[0009] Preferably, the conveying mechanism includes a first driving wheel, a first driven wheel, and a first chain wrapped around the first driving wheel and the first driven wheel. The robotic gripper is fixed on the first chain, and the first chain drives the robotic gripper to move under the drive of the first driving wheel and the first driven wheel.

[0010] Preferably, the gizzard opening frame further includes a guide assembly for guiding the movement of the robotic arm. The guide assembly includes a guide rail and a slide. The slide has an upward position and a downward position. When the robotic arm moves to the upward position of the slide, it unfolds to place the duck gizzard on the robotic arm. When it moves to the downward position of the slide, the robotic arm closes to hold the duck gizzard.

[0011] Preferably, the cutting mechanism includes a lifting motor and a cutting blade connected to the lifting motor. Under the control of a height signal, the lifting motor drives the cutting blade to rise and fall to a corresponding height to cut open the duck gizzard.

[0012] Preferably, the gizzard-opening frame also includes a slide bar connecting the gizzard-opening mechanism and the cleaning mechanism, and the cut duck gizzards slide from the slide bar to the cleaning mechanism for cleaning.

[0013] Preferably, the duck gizzard pushing mechanism includes a chain drive motor, a pair of relatively rotating first gears and second gears, and two sets of chain assemblies. The chain drive motor is connected to the first gear via a drive shaft. The first gear meshes with the second gear. The two sets of chain assemblies are respectively connected to the first gear and the second gear. While the first gear and the second gear rotate relative to each other, they perform relative transmission. The cut duck gizzard is located between the two sets of chain assemblies and is pushed to the roller brush mechanism by the two sets of chain assemblies.

[0014] Preferably, each chain assembly includes two second chains distributed parallel to each other and multiple chain rods vertically supporting the two second chains. Each second chain is wrapped around a set of second driving wheels and second driven wheels. The upper and lower second driving wheels of one of the two sets of chain assemblies are coaxially arranged and fixed on the drive shaft of the chain drive motor.

[0015] Preferably, the roller brush mechanism includes two roller brushes and a roller brush motor connected to the roller brushes. The duck gizzard pushing mechanism pushes the duck gizzards on the duck gizzard support shaft between the two roller brushes, and the roller brushes clean the debris inside the duck gizzards under the drive of the roller brush motor.

[0016] Preferably, the turntable mechanism includes a turntable motor and a turntable connected to the turntable motor, and a plurality of duck gizzard grooves are arranged circumferentially around the outer periphery of the turntable.

[0017] Preferably, the gizzard grinding wheel mechanism includes two sets of gizzard grinding wheel assemblies. Each set of gizzard grinding wheel assemblies includes a gizzard grinding wheel motor and a pair of gizzard grinding wheels. The gizzard grinding wheel motor is connected to one of the gizzard grinding wheels via a third chain, driving the gizzard grinding wheel to rotate. The pair of gizzard grinding wheels rotate relative to each other through gear transmission. Each gizzard grinding wheel is also mounted on a gizzard grinding wheel fixing plate that can rotate around a fixed axis. While the pair of gizzard grinding wheels are rotating relative to each other, they can also swing on the gizzard grinding wheel fixing plate. The turntable brings the duck gizzard between each pair of gizzard grinding wheels, while simultaneously opening the gizzard grinding wheel fixing plate to pass through the middle. During the passage, the pair of gizzard grinding wheels rotate to grind off the yellow skin of the duck gizzard.

[0018] Preferably, the turntable mechanism further includes a groove disposed on the side of the turntable and close to the gizzard grinding wheel mechanism, into which the ground duck gizzards fall and slide out.

[0019] The beneficial effects of this invention are:

[0020] 1. This equipment automatically cuts, cleans, and grinds off the yellow skin of duck gizzards, reducing the number of operators from 8 to just 2, saving 6 workers per duck slaughtering line and significantly reducing labor costs.

[0021] 2. The automatic cutting mechanism of this equipment is designed with a robotic gripper that can adapt to different sizes and shapes of duck gizzards, enabling automatic positioning of duck gizzards of different sizes. Combined with a height sensor, it ensures accurate cutting position.

[0022] 3. The automatic cleaning mechanism in this equipment uses a roller brush to clean out the contents of the duck gizzard, saving water. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will now be clearly and completely described with reference to the accompanying drawings.

[0041] The present invention discloses an automatic duck gizzard opening, cleaning and grinding production device, which automatically realizes the production process of cutting duck gizzards, cleaning and grinding off the yellow skin of duck gizzards, thereby reducing labor costs.

[0042] Combination Figures 1-5 As shown in the embodiment of the present invention, an automatic duck gizzard opening, cleaning and grinding production device includes a gizzard opening mechanism 100, a cleaning mechanism 200 and a gizzard grinding mechanism 300 connected in sequence, and an electrical control system 400. Under the control of the electrical control system 400, the gizzard opening mechanism 100, the cleaning mechanism 200 and the gizzard grinding mechanism 300 automatically complete the operations of cutting duck gizzards, cleaning duck gizzards, and grinding off the yellow skin of duck gizzards.

[0043] Specifically, in combination Figures 6-9 As shown, in this embodiment, the gizzard opening mechanism 100 includes a gizzard opening frame 101 and a conveying mechanism, a robotic gripper 102, a height sensor 103, and a cutting mechanism disposed on the gizzard opening frame 101. The conveying mechanism includes a first driving wheel 104, a first driven wheel 105, and a first chain 106 wrapped around the first driving wheel 104 and the first driven wheel 105. The first driving wheel 104 is driven by a conveying motor 114, which drives the first driven wheel 105 to rotate via the first chain 106. The robotic gripper 102 is fixed to the first chain 106.

[0044] Preferably, the gizzard opening frame 101 also includes a guide assembly for guiding the movement of the robotic gripper 102. The guide assembly specifically includes a guide rail 107 and a slide rail 108. The slide rail 108 has a rising position 109 and a falling position 110. The rising position 109 is located away from the cleaning mechanism 200, i.e., close to the worker's position, while the falling position 110 is located close to the height sensor 103. The robotic gripper 102 moves in the guide rail 107 along with the movement of the first chain 106. When the robotic gripper 102 moves to the rising position 109 of the slide rail 108 (i.e., from a low position to a high position), the bearing (not shown) on the robotic gripper 102 rises, pushing the robotic gripper 102 upwards and unfolding it. At this time, the worker manually places the duck gizzard onto the robotic gripper 102. The robotic arm 102 continues to move forward (i.e., towards the height sensor). When it reaches the descending position 110 of the slide (i.e., moving from a high position to a low position), the robotic arm 102 closes up and holds the duck gizzard.

[0045] Subsequently, when the robotic arm 102 continues to move to the position of the height sensor 103, the height sensor 103 detects the height of the duck gizzard and transmits the height signal to the electrical control system 400, which then calculates the cutting depth of the duck gizzard. In practice, the electrical control system 400 can be implemented using a PLC.

[0046] The cutting mechanism is connected to the electrical control system 400. In this embodiment, the cutting mechanism includes a lifting motor 111 and a cutter 112 connected to the lifting motor 111. The lifting motor 111 is connected to the electrical control system 400, and the electrical control system 400 controls the lifting motor 111 to rise and fall according to the calculated duck gizzard cutting depth. The cutter 112 is located at the front end of the height sensor 103, that is, close to the cleaning mechanism 200. Under the control of the lifting motor 111, it descends to the corresponding height to cut open the duck gizzard, thus achieving gizzard opening.

[0047] Furthermore, the gizzard opening mechanism 100 also includes a slide bar 113 connecting the gizzard opening mechanism 100 and the cleaning mechanism 200. The duck gizzards cut by the cutter slide from the slide bar 113 to the cleaning mechanism 200 for cleaning.

[0048] In this embodiment, the cleaning mechanism 200 specifically includes a cleaning frame 201 and a duck gizzard support shaft 202, a set of duck gizzard pushing mechanisms, and a roller brush mechanism disposed on the cleaning frame 201. The set of duck gizzard pushing mechanisms includes a chain drive motor 203, a pair of relatively rotating first gears 204 and second gears, and two sets of chain assemblies. Specifically, the chain drive motor 203 is connected to the first gear 204 through a drive shaft 206. The first gear 204 meshes with the second gear 205. That is, the chain drive motor 203 drives the first gear 204 to rotate through the drive shaft 206, and the first gear 204 then drives the second gear 205 to rotate, thereby realizing the relative rotation of the two gears 204 and 205.

[0049] Two sets of chain assemblies are arranged opposite to each other, and are respectively connected to the first gear 204 and the second gear 205. They perform relative transmission while the first gear 204 and the second gear 205 rotate relative to each other. The duck gizzard support shaft 202 is located between the two sets of chain assemblies, with its lower end fixed to the washing frame 201 and its upper end supporting the cut duck gizzard. Figure 11 The duck gizzard shown enters position 213 and enters the duck gizzard support shaft 202 of the cleaning mechanism 200. The two sets of chain assemblies simultaneously push the cut duck gizzard to the roller brush mechanism.

[0050] In this embodiment, each chain assembly includes two parallel second chains 207 and multiple chain rods 208 vertically supporting the two second chains 207. Each second chain 207 is wound around a set of second driving wheels 209 and second driven wheels 210. The upper and lower two driving wheels 209 of one of the chain assemblies are coaxially arranged and fixed on the drive shaft of the chain drive motor 203, i.e., coaxially arranged with the first gear 204. The upper and lower two driving wheels 209 of the other chain assembly are coaxially arranged with the second gear 205. That is, the first gear 204 drives the upper and lower two driving wheels 209 coaxially with it to rotate. These two driving wheels 209 drive the other two second driven wheels 210 in the same group to rotate through their respective corresponding second chains 207. The chain rods 208 between the upper and lower second chains 207 are synchronously driven with the second chains 207. Driven by the first gear 204, the second gear 205 drives the two upper and lower second driving wheels 209 on the same axis to rotate. These two second driving wheels 209 drive the other two second driven wheels 210 in the same group to rotate through their respective second chains 207. The chain link 208 between the upper and lower second chains 207 drives synchronously with the second chains 207. In this way, the chain link 208 of the two sets of chain assemblies pushes the duck gizzard on the duck gizzard support shaft 202 forward and transfers it through the roller brush mechanism.

[0051] In this embodiment, the roller brush mechanism includes two roller brushes 211 and two roller brush motors 212. Each roller brush motor 212 is connected to one roller brush 211. The chain assembly of the duck gizzard pushing mechanism pushes the duck gizzard on the duck gizzard support shaft 202 between the two roller brushes 211. The two roller brushes 211 rotate relative to each other under the drive of their respective roller brush motors 212, cleaning the debris inside the duck gizzard. After cleaning, the duck gizzard is pushed from the duck gizzard support shaft 202 by the chain rod 208 to the gizzard grinding mechanism 300 for grinding the yellow skin.

[0052] In this embodiment, the gizzard grinding mechanism 300 specifically includes a gizzard grinding frame 301 and a turntable mechanism and a gizzard grinding wheel mechanism disposed on the gizzard grinding frame 301. The turntable mechanism includes a turntable motor 302 and a turntable 303 connected to the turntable motor 302. Multiple gizzard grooves 304 are circumferentially arranged around the outer periphery of the turntable 303. The cleaned gizzards are fed from the cleaning mechanism 200 through... Figure 14 The duck gizzard shown in the diagram is pushed into the duck gizzard groove 304 of the turntable 303 at position 313. The turntable 303, driven by the turntable motor 302, moves the duck gizzard to the grinding wheel mechanism.

[0053] In this embodiment, the grinding wheel mechanism includes two sets of grinding wheel assemblies. Each set of grinding wheel assemblies includes a grinding wheel motor 305 and a pair of grinding wheels 306. The grinding wheel motor 305 is connected to one of the grinding wheels 306 via a third chain 307, driving the grinding wheel 306 to rotate. The pair of grinding wheels 306 are also driven to rotate relative to each other by a pair of gears (defined as a third gear 308 and a fourth gear 309). Thus, the grinding wheel motor 305 drives the third gear 308 to rotate, and the third gear 308 drives the grinding wheel 306 connected to it via the third chain 307. The third gear 308 also drives the fourth gear 309, which meshes with it, to rotate relative to each other. The fourth gear 309 drives the other grinding wheel 306 connected to it to rotate via the third chain 307. In this way, the two grinding wheels 306 can rotate relative to each other under the drive of one grinding wheel motor 305.

[0054] Preferably, each grinding wheel 306 is also mounted on a grinding wheel fixing plate 310, which can rotate around a fixed shaft 311, thereby enabling the pair of grinding wheels 306 to swing on the grinding wheel fixing plate 310 while rotating relative to each other.

[0055] In this way, the duck gizzards are pushed from the cleaning mechanism 200 into the duck gizzard groove 304 of the turntable 303. The turntable 303 is driven by the turntable motor 302 to perform intermittent motion. The turntable 303 brings the duck gizzards between each pair of grinding wheels 306, and at the same time, it opens the grinding wheel fixing plate 310 to pass between each pair of grinding wheels 306. During the passage of the duck gizzards, the grinding wheels 306 rotate to grind off the yellow skin of the duck gizzards, thus realizing the grinding function.

[0056] Furthermore, the gizzard grinding wheel mechanism also includes a chute 312, which is located on the side of the turntable 303 and close to the gizzard grinding wheel mechanism. The ground duck gizzards fall onto the chute 312 and slide out into a manually placed box.

[0057] In this way, through the cooperation of the gizzard opening mechanism 100, the cleaning mechanism 200 and the gizzard grinding mechanism 300 on this equipment, the production process of automatically cutting, cleaning and grinding off the yellow skin of duck gizzards is realized, which greatly reduces labor costs.

[0058] The technical content and features of the present invention have been disclosed above. However, those skilled in the art may still make various substitutions and modifications that do not depart from the spirit of the present invention based on the teachings and disclosures of the present invention. Therefore, the scope of protection of the present invention should not be limited to the content disclosed in the embodiments, but should include various substitutions and modifications that do not depart from the present invention, and should be covered by the claims of this patent application.
