Description

Technical Field

[0001] The invention relates to the technical field of seafood deboning, in particular to a deboning device for reducing the loss of vacuum-packed frozen seafood. Background Art

[0002] Currently, there's no precedent for removing the spines from shrimp and crabs before packaging. Vacuum packaging is also difficult for seafood with spiny shells like crabs, significantly shortening their shelf life in a non-vacuum environment. The spines on the surfaces of crustaceans like crabs and lobsters, such as those at the joints of their chelicerae, are highly hard and irregularly distributed, making them susceptible to puncturing packaging materials under the negative pressure of vacuum packaging. The lanceolate in shrimp heads increases in brittleness after freezing, making them susceptible to breaking during vacuum sealing and embedding into the packaging, causing leaks.

[0003] The current mainstream deboning method relies on manual labor, with workers using handheld tools like tweezers or scissors for surface treatment. This is extremely inefficient and cannot keep up with the speed of modern packaging lines. During peak fishing seasons, labor shortages further exacerbate bottlenecks and lead to wasted production capacity. When humans handle frozen seafood, human pathogens or improperly cleaned tools can lead to cross-contamination, compromising the freshness of the product.

[0004] Based on this, a thorn removal device for reducing the loss of vacuum-packed frozen seafood is now provided, which can eliminate the disadvantages of existing devices. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In one embodiment, Figure 1-Figure 7 As shown, a thorn removal device for reducing the loss of vacuum packaging of frozen seafood includes a box body 1, a thorn removal assembly, and a drive assembly. A feed port is opened on one side of the box body 1. Rotating plates 3 are connected to opposite side walls of the box body 1 through bearings. A knife net 18 is fixedly connected between the two rotating plates 3. A fixing frame 9 is fixedly connected to the inner wall of the box body 1.

[0033] The thorn removal component is arranged between the two rotating plates 3 to improve the thorn removal effect of the device;

[0034] The driving assembly is arranged on the fixing frame 9 and is used to drive the thorn removal assembly to perform rotary thorn removal.

[0035] In one embodiment, the driving assembly includes a third gear 15 and a ring gear 16. A motor 10, a bevel gear set 14, and a third gear 15 are provided on the fixed frame 9. The motor 10 drives the bevel gear set 14 to rotate through a belt transmission member 13. The side wall of the box body 1 is provided with a third gear 15 through shaft rotation. The bevel gear set 14 is connected to the third gear 15, driving the third gear 15 to rotate. One of the rotating plates 3 is fixedly connected to the ring gear 16, and the third gear 15 is engaged with the ring gear 16.

[0036] Start the motor 10, and the motor 10 drives the bevel gear set 14 to rotate through the belt transmission part 13. The bevel gear set 14 drives the third gear 15 to rotate, and the third gear 15 drives the ring gear 16 to rotate. The ring gear 16 drives the rotating plate 3 to rotate, and the rotating plate 3 drives the knife net 18 to rotate. When the sharp spines of shrimps and crabs enter the mesh of the knife net 18, the knife net 18 can rotate to remove the spines of the shrimps and crabs put into the box body 1.

[0037] In one embodiment, the thorn removal assembly includes a first rack 21, a second rack 24, and a second gear 12. Several guide rails 22 are fixedly connected to the periphery of the knife net 18. The first rack 21 is slidably provided on the side wall of the guide rail 22. Several fourth gears 23 are provided on the periphery of the knife net 18 through a rotating shaft. The fourth gear 23 is engaged with the first rack 21. Several second racks 24 are provided on the periphery of the knife net 18. The fourth gear 23 is engaged with the second rack 24. Several second racks 24 are connected by a hinge 17. Several second racks 24 are fixedly connected to an arc-shaped blade 26. Several first racks 21 are fixedly connected to a trapezoidal blade 25. The shape of the knife net 18 corresponds to the shape of the trapezoidal blade 25 and the arc-shaped blade 26. The knife net 18 is slidably connected to the trapezoidal blade 25 and the arc-shaped blade 26.

[0038] When the knife net 18 rotates to remove thorns, the handle 7 drives the second rack 24 to move back and forth horizontally, and the second rack 24 drives the curved blade 26 to move back and forth. The curved blade 26 cooperates with the knife net 18, and the shape of the curved blade 26 and the knife net 18 fits tightly, cutting the sharp thorns that enter the knife net 18. Since the contact area between the curved blade 26 and the knife net of the corresponding shape and the seafood is small, a greater pressure can be generated under the action of gravity, which is convenient for processing large seafood with hard shells such as crabs;

[0039] It can efficiently remove the thorns of some crabs and seafood, and has a good thorn removal effect;

[0040] While the second rack 24 is moving back and forth laterally, it drives the first rack 21 to reciprocate through the fourth gear 23. The first rack 21 drives the arc-shaped blade 26 to reciprocate. The arc-shaped blade 26 cooperates with the knife net 18 to remove the bones of seafood. The trapezoidal blade 25 and the knife net 18 of the corresponding shape have a large contact area with the seafood, which is suitable for processing small seafood with a lot of whiskers, such as shrimp.

[0041] In one embodiment, the side walls of several second racks 24 are fixed with handles 7 by bolts, the output end of the motor 10 is fixedly connected to the second gear 12, and the fixed frame 9 is provided with two symmetrical first gears 5 through the rotation of the rotating shaft. The upper surfaces of the two first gears 5 are fixedly connected with eccentric rods 11, and the two first gears 5 are engaged with the second gear 12. The two eccentric rods 11 are slidably matched with the moving frame 8, and the moving frame 8 is slidably connected to the handle 7.

[0042] The motor 10 drives the second gear 12 to rotate, the second gear 12 drives the two first gears 5 to rotate in the same direction, the first gear 5 drives the two eccentric rods 11 to rotate, the two eccentric rods 11 are initially in the same position, the two eccentric rods 11 drive the moving frame 8 to move, and the moving frame 8 drives the handle 7 to move left and right.

[0043] In one embodiment, one end of the first rack 21 is connected to the rotating plate 3 through a V-shaped spring 19, and the other end is connected to the ring gear 16 through a V-shaped spring 19. One end of the arc-shaped blade 26 is connected to the rotating plate 3 through a W-shaped spring 20, and the other end is connected to the ring gear 16 through a W-shaped spring 20.

[0044] The first rack is connected to the rotating plate and the gear ring through a V-shaped spring, and the arc-shaped blade is connected to the rotating plate and the gear ring through a W-shaped spring. This elastic connection method can play a buffering role during the burr removal process, reduce the wear of the device components, and extend the service life of the device.

[0045] In one embodiment, the opposite side walls of the box body 1 are provided with a plurality of rollers 6 which are rotatable via a rotating shaft, and the plurality of rollers 6 abut against the rotating plate 3, so that the rotating plate 3 can rotate more stably.

[0046] In one embodiment, a plurality of movable wheels 2 are provided on the lower surface of the box body 1 , and each of the plurality of movable wheels 2 is provided with a wheel lock.

[0047] Facilitates movement of the device.

[0048] In one embodiment, four inclined plates 4 distributed circumferentially are fixedly connected to the inner wall of the blade net 18 .

[0049] Live fish, shellfish and other seafood will naturally secrete a layer of mucus on their body surface. If a large amount of seafood enters this device, the individual seafood will gradually spread out in the device or even slide out of the device due to the lubrication of the mucus on the surface of the seafood and the action of gravity. When the device starts the deboning operation, the seafood is more likely to fall out of the device due to the flipping of the device. The present invention loads and unloads on the same side. Four inclined plates 4 are installed on the surface of the drum-type knife net 18 in the box body 1. When loading, the device knife net 18 drives the rotation of the inclined plates 4, so that the seafood will move toward the inside of the device along the inclined trajectory of the inclined plates 4 when flipping, ensuring that the seafood can always be continuously flipped inward in the drum-type knife net 18 without the seafood being scattered outward. When unloading, it is only necessary to reverse the motor 10, and the rotation of the drum-type knife net 18 and the inclined plates 4 can make the seafood after deboning easily unload outward along the trajectory of the inclined plates 4, effectively improving the unloading efficiency of the device.

[0050] The above embodiment discloses a thorn removal device for reducing the loss of vacuum packaging of frozen seafood. The specific working principle and process are as follows:

[0051] S1: Start the motor 10. The motor 10 drives the bevel gear set 14 to rotate through the belt transmission member 13. The bevel gear set 14 drives the third gear 15 to rotate. The third gear 15 drives the ring gear 16 to rotate. The ring gear 16 drives the rotating plate 3 to rotate. The rotating plate 3 drives the knife net 18 to rotate. When the sharp spines of shrimps and crabs enter the mesh of the knife net 18, the knife net 18 can rotate to remove the spines of the shrimps and crabs put into the box 1.

[0052] When the motor 10 drives the blade net 18 to rotate in the forward direction, under the action of the inclined plate 4, similar to the principle of a screw rod, shrimps and crabs can be transported into the box body 1.

[0053] S2: When the knife net 18 rotates to remove thorns, the motor 10 drives the second gear 12 to rotate, and the second gear 12 drives the two first gears 5 to rotate in the same direction. The first gear 5 drives the two eccentric rods 11 to rotate. The two eccentric rods 11 are initially in the same position. The two eccentric rods 11 drive the movable frame 8 to move, and the movable frame 8 drives the handle 7 to move horizontally left and right. The handle 7 drives the second rack 24 to move back and forth horizontally. The second rack 24 drives the curved blade 26 to move back and forth. The curved blade 26 cooperates with the knife net 18. The curved blade 26 fits the shape of the knife net 18 tightly and cuts the sharp thorns that enter the knife net 18. Since the curved blade 26 and the knife net of the corresponding shape have a small contact area with the seafood, they can generate greater pressure under the action of gravity, which is convenient for processing large seafood with hard shells such as crabs.

[0054] It can efficiently remove the thorns of some crabs and seafood, and has a good thorn removal effect;

[0055] While the second rack 24 is moving back and forth laterally, it drives the first rack 21 to reciprocate through the fourth gear 23. The first rack 21 drives the arc-shaped blade 26 to reciprocate. The arc-shaped blade 26 cooperates with the knife net 18 to remove the bones of seafood. The trapezoidal blade 25 and the knife net 18 of the corresponding shape have a large contact area with the seafood, which is suitable for processing small seafood with a lot of whiskers, such as shrimp.

[0056] The knife net 18 used in the present invention is an ultra-thin knife net. When the whiskers or piercings of seafood penetrate into the knife net 18, they will be cut off by the trapezoidal blade 25 and the curved blade 26 that reciprocate at high frequency. The trapezoidal blade 25 is suitable for small shrimps and seafood, and the curved blade 26 is suitable for large crabs and seafood. The device is applicable to a wide variety of seafood and has a wide range of applications.

[0057] S3: After the seafood products are deboned, the motor 10 is controlled to rotate in the reverse direction, driving the blade net 18 to rotate in the reverse direction. Under the action of the inclined plate 4, the deboned shrimps and crabs are transported out of the box 1 for easy picking by the staff.

[0058] Live fish, shellfish and other seafood will naturally secrete a layer of mucus on their body surface. If a large amount of seafood enters this device, the individual seafood will gradually spread out in the device or even slide out of the device due to the lubrication of the mucus on the surface of the seafood and the action of gravity. When the device starts the deboning operation, the seafood is more likely to fall out of the device due to the flipping of the device. The present invention loads and unloads on the same side. Four inclined plates 4 are installed on the surface of the drum-type knife net 18 in the box body 1. When loading, the device knife net 18 drives the rotation of the inclined plates 4, so that the seafood will move toward the inside of the device along the inclined trajectory of the inclined plates 4 when flipping, ensuring that the seafood can always be continuously flipped inward in the drum-type knife net 18 without the seafood being scattered outward. When unloading, it is only necessary to reverse the motor 10, and the rotation of the drum-type knife net 18 and the inclined plates 4 can make the seafood after deboning easily unload outward along the trajectory of the inclined plates 4, effectively improving the unloading efficiency of the device.

[0059] In order to facilitate use and maintenance, the present invention is provided with a handle 7, which can drive the blade to reciprocate when in working state; when the blade needs to be disassembled for replacement, the bolt can be loosened, and then the handle 7 can be rotated ninety degrees, and a pair of hinges 17 can be removed, and all the curved blades 26 can be easily removed together as if removing a chain. This quick-release design saves time and effort.

[0060] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
