Description

Technical Field

[0001] The invention relates to a precise cutting and deboning mechanism for an eel slaughtering machine, belonging to the technical field of aquatic product processing machinery. Background Art

[0002] Eels and loaches are beloved by diners for their delicate texture and rich nutrition. Traditionally, eels and loaches are cooked by hand, slaughtering and deboning them. However, with the development of aquaculture, loaches and eels have become factory-farmed, and with it, a large number of processed, ready-to-eat foods have become available. Clearly, manually slaughtered and deboned eels and loaches cannot meet the demands of factory-based farming and processing. The patent document with application number 201910162532.8, entitled "A Machine for Deboning and Slaughtering Eels and Loaches", discloses a machine for deboning and slaughtering eels and loaches, which pours the eels and loaches in the feed box through the discharge pipe into the slaughtering conveyor plate, and uses a rotating deboning roller to complete the slaughtering and deboning of the eels and loaches. However, due to the assembly angle of the deboning roller, the meat content of the removed fish bones is relatively high. On the other hand. During the process of slaughtering eels and loaches, the slaughtering machine relies on symmetrically arranged rollers as power wheels to push the fish body forward. However, due to the physical structure of eels and loaches, the slaughtering knife (slaughtering mouth) is very likely to deviate. Once deviated, it will directly affect the effect of removing fish bones. Therefore, it is necessary to improve it. Summary of the Invention

[0003] The purpose of the present invention is to provide a precise cutting and deboning mechanism for an eel and loach slaughtering machine, which has a simple structure, good practicality and effectively improves the bone removal effect of eels and loaches.

[0004] The technical solution of the present invention is:

[0005] A precise cutting and deboning mechanism for an eel slaughtering machine comprises a transmission gear disc, a horizontal conveying wheel, a feeding pipe, a deboning guide block, a deboning guard plate and a deboning knife; the mechanism is characterized in that: horizontal conveying wheels are symmetrically installed horizontally at both ends of the outlet of the feeding pipe through a motor, a deboning knife is installed between the horizontal conveying wheels through a motor, deboning guard plates are symmetrically installed on one side of the transmission gear disc and the deboning knife through a frame, a deboning guide block is installed on the frame between the deboning guard plates, a transmission gear disc is installed above the deboning guide block through the frame, and a deboning knife is symmetrically installed below the deboning guide block through the frame.

[0006] The boning knife is arranged in an eight-shaped shape.

[0007] The deboning guide block is wedge-shaped, with multiple anti-slip teeth on one end and symmetrical gaps on the other end. Multiple adjustment holes are provided on the deboning guide block between the gaps and the anti-slip teeth.

[0008] The deboning guard plate is in the shape of a long strip, with a first arc-shaped groove provided on the inner side of the deboning guard plate, a first slope provided on the deboning guard plate at one end of the first arc-shaped groove, a second slope provided on the deboning guard plate at the angle between the first slope and the first arc-shaped groove, and a second arc-shaped groove provided on the outer side of the deboning guard plate.

[0009] The beneficial effects of the present invention compared with the prior art are:

[0010] The precise cutting and deboning mechanism of the eel and loach slaughtering machine pushes the eel or loach toward the cutting knife under the grip of two horizontal conveying wheels, and the eel or loach is opened with the rotation of the cutting knife; after the eel or loach is opened, it moves to the position of the conveying gear disc, and the anti-skid teeth of the deboning guide block can effectively prevent the eel or loach from slipping due to the reaction force when the conveying gear disc compacts the eel or loach and pushes it forward. The eel or loach will move backward, and the boning knife position will continue to move forward under the cooperation of the transmission gear disc and the boning guide block. During this process, under the limitation of the boning guard plate, the eel or loach will remain in a straight state. After passing through the boning knife that is arranged in an eight-shaped shape and rotates continuously, the fish bones will be removed. The precise cutting and boning mechanism of the eel and loach slaughtering machine can effectively prevent the fish body from deviating, and the removed fish bones have a low meat content, which effectively ensures the fish bone removal effect.

[0017] As attached Figure 1-5 shown

[0018] The precise cutting and deboning mechanism of the eel slaughtering machine includes a transmission gear disc 1, a horizontal conveying wheel 2, a feeding pipe 3, a deboning guide block 4, a deboning guard plate 5 and a deboning knife 6; the feeding pipe 3 is fixedly mounted on a frame 19, and horizontal conveying wheels 2 are symmetrically arranged at both ends of the outlet of the feeding pipe 3, and the horizontal conveying wheels 2 are connected by a gear rack synchronous opening and closing assembly 25, and the gear rack synchronous opening and closing assembly 25 is a prior art, and the gear rack synchronous opening and closing assembly 25 is composed of a guide rod, a slider, a slide plate, a gear, a first rack, a second rack and an assembly The seat is composed of a guide rod fixedly mounted on the frame, two slides are installed on the guide rod through a slider, and the two slides can slide along the guide rod through their corresponding sliders. An assembly seat is fixedly mounted on the frame between the slides, and a first rack and a second rack are installed on the assembly seat through a gear staggered movement. The first rack and the second rack are respectively engaged with the gear, and the first rack and the second rack are respectively fixedly connected to the corresponding slides. Therefore, during use, the first rack, the second rack and the gear cooperate to realize the synchronous opening and closing of the horizontal conveying wheel 2.

[0019] Conveying teeth are provided on the circumference of the horizontal conveying wheel 2. A conveying motor 7 is fixedly installed on the slide of the gear rack synchronous opening and closing assembly 25 above the horizontal conveying wheel 2. The transmission shaft of the conveying motor 7 is fixedly connected to the center hole of the horizontal conveying wheel 2. When in use, the transmission shaft of the conveying motor 7 drives the horizontal conveying wheel 2 to rotate.

[0020] A cutting shaft 8 is movably installed on the frame 19 between the horizontal conveying wheels 2 through a support seat, a cutting knife 9 is fixedly installed on the cutting shaft 8, and a cutting motor 10 is fixedly installed on the frame 19 below the cutting knife 9. A driving pulley is fixedly installed on the transmission shaft of the cutting motor 10, and a driven pulley is fixedly installed on the cutting shaft 8 corresponding to the driving pulley. The driving pulley and the driven pulley are connected by a transmission belt. When in use, the transmission shaft of the cutting motor 10 drives the cutting shaft 8 to rotate through the driving pulley, the driven pulley and the transmission belt, and the cutting shaft 8 drives the cutting knife 9 to rotate.

[0021] A deboning guard plate 5 is symmetrically installed on one side of the conveying gear disc 1 and the cutting knife 9 through the frame 19. One end of the deboning guard plate 5 is connected to the slide of the gear rack synchronous opening and closing assembly 25. When the slide of the gear rack synchronous opening and closing assembly 25 performs a synchronous opening and closing action, the two deboning guard plates 5 are driven to open and close synchronously together.

[0022] The other end of the boning guard plate 5 is connected to the frame 19 through a tension spring and a limit roller. The tension spring is installed between the boning guard plates 5. A limit roller is movably installed on each boning guard plate 5. A limit groove is provided on the frame 19 corresponding to the limit roller. The limit groove is oblong. The limit roller and the limit groove are slidably connected. When in use, the balance of the two ends of the boning guard plate 5 is maintained by the elastic force of the tension spring, and the stability of the movement of the boning guard plate 5 is ensured by the cooperation of the limit roller and the limit groove.

[0023] The deboning guard plate 5 is in the shape of an elongated strip, and a first arcuate groove 11 is provided on the inner side of the deboning guard plate 5 . The first arcuate groove 11 is used to make way for the transmission gear disc 1 so that the transmission gear disc 1 can contact the eel or loach between the deboning guard plates 5 .

[0024] A first slope 12 is provided on the deboning guard plate 5 at one end of the first arc-shaped groove 11 . The purpose of such provision is to guide the eel or loach to move toward the inside of the deboning guard plate 5 through the first slope 12 .

[0025] A second slope 13 is provided on the boning guard plate 5 at the angle between the first slope 12 and the first arc-shaped groove 11. The purpose of such setting is that the second slope 13 effectively increases the space between the boning guard plate 5 and the anti-sliding block to accommodate the eel or loach, thereby keeping the fish chamber of the eel or loach open.

[0026] A second arc-shaped groove 14 is provided on the outer side of the deboning guard plate 5. The second arc-shaped groove 14 is used to make way for the horizontal conveying wheel 2 so as to increase the pushing stroke of the horizontal conveying wheel 2 and reduce the connection distance between the horizontal conveying wheel 2 and the deboning guard plate 5, thereby ensuring that the horizontal conveying wheel 2 is smoother when pushing the eel or loach to the deboning guard plate 5.

[0027] A deboning guide block 4 is fixedly installed on the frame 19 between the deboning guard plates 5. The front end of the deboning guide block 4 is sloped, and the front end of the sloped deboning guide block 4 is in a "U" shape. Anti-slip teeth 24 are symmetrically provided on both sides. The purpose is to make way for the cutting knife 9 through the notch (through groove) between the anti-slip teeth 24, so that the cutting knife 9 can extend from the notch between the anti-slip teeth 24 to achieve the cutting of the eel or loach's abdomen and continue to push the fish body forward; at the same time, the anti-slip teeth 24 can effectively prevent the eel or loach from being squeezed when the conveying toothed disc 1 and the deboning guide block 4 compact the eel or loach body and push it forward, and the eel or loach will slip and retreat on the front end slope of the deboning guide block 4, thereby ensuring that the conveying toothed disc 1 and the deboning guide block 4 continue to move forward smoothly to the position of the deboning knife 6 under the cooperation of the conveying toothed disc 1 and the deboning guide block 4.

[0028] The other end of the deboning guide block 4 is symmetrically inclined with a clearance notch 15 (concave surface) to make way for the deboning knife 6 arranged in an eight-shaped shape, ensuring that the deboning guide block 4 opens the fish chamber while the deboning knife 6 can enter the fish chamber for deboning.

[0029] A plurality of adjustment holes 16 are provided on the top of the deboning guide block 4, and a fixing hole is provided on the frame 19 corresponding to the adjustment hole 16. The deboning guide block 4 is locked on the frame 19 by inserting the locking bolts into the adjustment hole 16 and the fixing hole. When in use, the distance between the transmission gear disc and the deboning guide block 4 is adjusted by cooperating with different adjustment holes 16 and the fixing holes, thereby adapting to eels or loaches of different sizes and specifications through different sizes of distances.

[0030] A movably hinged assembly plate 17 is mounted on the frame 19 above the deboning guide block 4. One end of the assembly plate 17 is connected to the frame 19 via an adjustable tension spring 18. The other end of the assembly plate 17 is movably mounted with a transmission shaft 23 via symmetrically arranged bearing seats. A transmission gear disc 1 is fixedly mounted on the transmission shaft 23 between the bearing seats. A transmission motor 20 is mounted on the assembly plate 17. The transmission shaft of the transmission motor 20 is connected to the transmission shaft 23 via a belt and a pulley. When in use, the transmission shaft of the transmission motor 20 drives the transmission shaft 23 to rotate via a belt and a pulley, and the transmission shaft 23 drives the transmission gear disc 1 to rotate.

[0031] The boning shafts 21 are symmetrically mounted on both sides of the frame 19 below the boning guide block 4 through bearings, and circular boning knives 6 are fixedly mounted on the boning shafts 21. The two boning knives 6 are arranged in an eight-shaped shape (the boning knives 6 are arranged at an angle, and the top edges are in contact with each other. They can also be arranged in an eight-shaped shape with different heights on the premise that the top edges are in contact with each other). A boning motor 22 is fixedly mounted in an inclined shape on the frame 19 corresponding to the boning knife 6. The drive shaft of the boning motor 22 is connected to the boning shaft 21. When in use, the boning shaft 21 is driven to rotate by the drive shaft of the boning motor 22, and the boning shaft 21 drives the boning knife 6 to rotate. The two boning knives 6 cooperate with each other to perform the boning operation.

[0032] When the precise cutting and deboning mechanism is used, taking eels as an example, when the eel slides out from the outlet of the feed pipe 3 to between the two horizontal conveying wheels 2, the two conveying motors 7 respectively drive their corresponding horizontal conveying wheels 2 to rotate synchronously in opposite directions. When the two horizontal conveying wheels 2 rotate synchronously in opposite directions, the conveying teeth on the circumference of the horizontal conveying wheel 2 grab the eel and push it forward to the cutting knife 9.

[0033] At the cutting knife 9, the cutting motor 10 drives the cutting knife 9 to rotate. During the movement of the eel, the cutting knife 9 cuts open the belly of the eel. While the belly of the eel is cut open, the eel continues to move forward due to the inertia of the horizontal conveying wheel 2. When the head of the eel (fish body) moves between the conveying gear disc 1 and the deboning guide block 4, the conveying motor 20 also drives the conveying gear disc 1 to rotate. The conveying gear disc 1 cooperates with the deboning guide block 4 to clamp the eel head. As the conveying gear disc 1 rotates, the deboning guide block 4 enters the eel's belly from one end of its teeth. As a result, the eel's belly wraps the deboning guide block 4; and the fish body continues to move forward under the action of the conveying gear disc 1.

[0034] As the eel continues to move forward, the deboning guard 5 limits the eel's position and cooperates with the deboning guide block 4 to clamp it, thus forcing the eel to move forward in a straight line and effectively preventing it from straying. The conveyor gear disc 1 and the deboning guide block 4 cooperate to clamp and propel the eel forward, while the anti-slip teeth 24 of the deboning guide block 4 effectively prevent the eel from being squeezed and pulled backward.

[0035] When the conveying gear disc 1 drives the eel to the position of the boning knife 6, the boning motor 22 drives the boning knife 6 to rotate, and the wedge-shaped boning guide block 4 has entered the belly of the fish to form a support for the eel (fish chamber). Under the downward pressure of the conveying gear disc 1, the edges of the two boning knives 6 arranged in an eight-shaped shape are located on both sides of the eel spine; the meat part is located on the outer surface of the boning knife 6. When the eel moves forward along the boning guide block 4, the boning knife 6 that extends into the eel's abdominal cavity and rotates will peel the eel's spine from the fish meat, thereby realizing the accurate and complete removal of the eel's spine.

[0036] The precise cutting and deboning mechanism of the eel slaughtering machine effectively prevents the fish body from deviating, and at the same time the removed fish bones have a low meat content, which effectively ensures the fish bone removal effect.
