Description

Technical Field

[0001] This invention relates to the field of aquatic product processing technology, and in particular to a conveying device and a deboning and eviscerating machine. Background Technology

[0002] Eels, with their delicate texture and high nutritional value, are a popular aquatic product in the market. However, their abundant mucus makes them slippery during slaughter, leading to low efficiency. Existing eel slaughtering machines typically employ a combination of horizontal and vertical clamping devices. The horizontal clamping device includes symmetrically arranged horizontal conveyor belts, forming a channel for transporting the eels. The vertical clamping device includes a vertical conveyor belt positioned between and above the two horizontal conveyor belts. During operation, the horizontal and vertical conveyor belts work together to transport the eels from the inlet to the outlet. However, the clamping force of this conveying structure is insufficient to accurately transport the eels onto the deboning support strip. During transport, the eels tend to drift to one side of the deboning support strip, hindering subsequent deboning and affecting the deboning effect. Summary of the Invention

[0003] The purpose of this invention is to provide a conveying device and a deboning machine to solve the problems existing in the prior art, so as to accurately convey the eel onto the deboning support strip and improve the deboning effect.

[0004] To achieve the above objectives, the present invention provides the following solution: This invention provides a conveying device, comprising: two parallel and spaced-apart conveying components and a clamping component. Each conveying component has a conveying plane, and a conveying channel for conveying a workpiece is formed between the two conveying planes. The conveying channel has a first end and a second end, and the direction from the first end to the second end within the conveying channel is the conveying direction. A ventricular cutting device and a deboning support strip are sequentially arranged within the conveying channel along the conveying direction. The symmetry plane of the conveying channel coincides with the symmetry plane of the deboning support strip. The conveying components are used to convey the workpiece from the first end to the second end so that the workpiece passes sequentially through the ventricular cutting device and the deboning support strip. The clamping component is used to apply clamping forces of opposite direction and equal magnitude to the portions of the two conveying planes facing each other or near the front end of the deboning support strip to clamp the ventricular cut workpiece, placing the workpiece in the center of the conveying channel.

[0005] In one embodiment, a friction layer is provided on one side surface of the two conveying planes that are arranged opposite to each other. The friction layer is used to provide contact friction with the object to be processed, so as to ensure that the object to be processed moves synchronously with the conveying planes.

[0006] In one embodiment, the two conveying components share a single power source.

[0007] In one embodiment, the clamping assembly includes a first elastic element, symmetrically arranged connecting elements, symmetrically arranged mounting elements, and symmetrically arranged tensioning wheels; The two mounting components are fixedly installed; The two tensioning pulleys are respectively disposed on the inner side of the two conveyor belts; One end of the connector is equipped with the tensioning wheel, and the other end is rotatably mounted on the mounting component, so that the two tensioning wheels can move away from or close to each other. The two ends of the first elastic element are respectively connected to the ends of the two connecting elements on which the tensioning wheels are installed, so that the two tensioning wheels apply clamping forces of opposite directions and the same magnitude to the parts of the two conveying planes that are facing each other or close to the front end of the debonding and spreading strip.

[0008] The present invention also discloses a laparotomy and deboning machine, including a frame, on which a laparotomy device, a deboning device and the above-mentioned conveying device are arranged; The conveying device is used to convey the object to be processed from the first end to the second end; The ventriloquism device is disposed in the conveying channel of the conveying device and is used to ventriloquize the object to be processed. The deboning device is located in the downstream conveying channel of the laparotomy device and is used to debon the object to be processed after laparotomy.

[0009] In one embodiment, a clamping device is also included, the clamping device comprising a deboning support strip, a deboning pressure strip, and an elastic support assembly; The deboning support strip is located downstream of the laparotomy device along the conveying direction and is used to support the laparotomized material to be processed. The deboning pressure strip is disposed above the deboning expansion strip to provide pressure to the workpiece toward the deboning expansion strip; The elastic support component is used to elastically support the deboning strip and enable the deboning strip to elastically float relative to the deboning support strip in a direction parallel to the conveying plane and perpendicular to the conveying direction, so as to adapt to the different sizes of the workpieces to be processed.

[0010] In one embodiment, the bottom of the deboning strip is provided with a guide groove, which extends along the conveying direction. The cross-section of the guide groove on a vertical plane perpendicular to the conveying direction is arc-shaped to conform to the spine curve of the object to be processed.

[0011] In one embodiment, the elastic support assembly includes an optical axis, a slider, a limiting part, and a second elastic element; The optical axis is vertically set; The slider is fixedly connected to the bone removal strip and slidably sleeved on the optical axis; The limiting part is disposed on the optical axis and located above the slider; The second elastic element is sleeved on the optical axis and located between the slider and the limiting part to provide elastic support for the bone removal strip.

[0012] In one embodiment, a material collection device is also included, which is disposed at the second end of the conveying device for collecting the deboned material to be processed.

[0013] In one embodiment, a spray washing device is further included, which is used to spray the conveying channel toward the conveying channel.

[0014] The present invention achieves the following technical effects compared to the prior art: This invention discloses a conveying device and a ventriloquization and deboning machine. By installing a clamping component near the first end of the deboning support bar, the clamping component applies equal force to the portion of the conveying component directly opposite or near the front end of the deboning support bar. Applying opposing forces further clamps the ventriloquist before it enters the deboning support bar. Applying the same clamping force automatically adjusts the device to the center of the conveying channel, ensuring the ventriloquist is accurately conveyed to the deboning support bar in a centered position. This effectively prevents the ventriloquist from veering to one side of the deboning support bar during conveying, ensuring the deboning support bar can smoothly open the ventriloquist's abdomen, significantly improving the stability and success rate of subsequent deboning operations. Furthermore, the clamping component is only positioned at the entrance of the deboning support bar near the first end, without applying clamping force throughout the entire conveying process. This ensures the ventriloquist enters the deboning support bar in a centered position, avoiding surface tissue damage caused by high clamping throughout the process, thus helping to maintain the material's appearance and subsequent processing quality.

[0017] The technical solutions of 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.

[0018] The purpose of this invention is to provide a conveying device and a deboning machine to solve the problems existing in the prior art, so as to accurately convey the eel onto the deboning support strip and improve the deboning effect.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] The inventors discovered that the relevant technology uses one vertical conveyor belt and two horizontal conveyor belts, with the two horizontal belts symmetrically arranged and the vertical belt positioned between and above the other two. The clamping structure formed by the horizontal and vertical belts provides insufficient clamping force for the eel, preventing it from being accurately conveyed onto the deboning and spreading strip. If the distance between the two belts is reduced to increase the clamping force, the eel will remain under high clamping pressure throughout the conveying process, easily damaging its surface tissue and severely affecting the quality of subsequent processing.

[0021] Example 1 like Figure 2 As shown, this embodiment provides a conveying device, including: a clamping assembly 1 and two parallel and spaced-apart conveying assemblies. Each conveying assembly has a conveying plane, and a conveying channel for conveying the object to be processed is formed between the two conveying planes. The conveying channel has a first end and a second end. The conveying direction is along the direction from the first end to the second end within the conveying channel. A ventricular cutting device 17 and a deboning support strip 20 are sequentially arranged within the conveying channel along the conveying direction. The symmetry plane of the conveying channel coincides with the symmetry plane of the deboning support strip 20. The conveying assembly is used to convey the object to be processed from the first end to the second end so that the object to be processed passes through the ventricular cutting device 17 and the deboning support strip 20 sequentially. The clamping assembly 1 is used to apply clamping forces of opposite direction and the same magnitude to the parts of the two conveying planes facing each other or close to the front end of the deboning support strip 20 to clamp the object to be processed after ventricular cutting, so that the object to be processed is in the center position of the conveying channel.

[0022] By setting a clamping component 1 near the first end of the deboning support bar 20, the clamping component 1 applies equal force to the part of the conveying component facing or near the front end of the deboning support bar 20. Applying forces in opposite directions allows the abdominally opened material to be further clamped before entering the deboning support bar 20. Applying the same clamping force can automatically adjust to the middle position of the conveying channel, thereby ensuring that the material is accurately conveyed to the deboning support bar 20 in a centered position. This effectively prevents the material from deviating to one side of the deboning support bar 20 during the conveying process, ensuring that the deboning support bar 20 can smoothly open the abdomen of the material, significantly improving the stability and success rate of subsequent deboning operations. Furthermore, the clamping component 1 is only arranged at the entrance position of the deboning support bar 20 near the first end, without applying clamping force throughout the entire conveying process. This avoids surface tissue damage caused by high clamping throughout the process while ensuring that the material enters the deboning support bar 20 in a centered position, which is beneficial for maintaining the appearance of the material and the quality of subsequent processing.

[0023] Furthermore, the material to be processed can be aquatic products such as eels and loaches.

[0024] In one embodiment, a friction layer is provided on one side surface of the two conveyor groups that are arranged opposite to each other. The friction layer is used to provide contact friction with the object to be processed, so as to ensure that the object to be processed moves synchronously with the conveyor plane.

[0025] Setting a friction layer on the surface of the conveyor plane can enhance the contact friction with the surface of the object to be processed, which can not only prevent the object from shifting, but also effectively reduce mechanical damage to its surface.

[0026] Furthermore, the friction layer can be made of rubber, plastic, or polymers.

[0027] In one implementation, the two conveying components share a single power source, which on the one hand ensures the synchronization of the two conveying components and improves the consistency of processing; on the other hand, it also saves costs and energy consumption.

[0028] In one specific embodiment, the power source is a first motor 3, and one conveying assembly includes a conveyor belt 2, a first gear 4, a third gear 6, and a fifth gear 8; another conveying assembly includes a conveyor belt 2, a second gear 5, a fourth gear 7, and a sixth gear 9. The output shaft of the first motor 3 is driven by the first gear 4, the first gear 4 meshes with the second gear 5, the first gear 4 drives the third gear 6 through a drive shaft, the second gear 5 drives the fourth gear 7 through a drive shaft, the third gear 6 is connected to the fifth gear 8 through the conveyor belt 2, and the fourth gear 7 is connected to the sixth gear 9 through the conveyor belt 2.

[0029] In one embodiment, the clamping assembly 1 includes a first elastic element 10, symmetrically arranged connecting parts 11, symmetrically arranged mounting parts 12, and symmetrically arranged tensioning wheels 13; the two mounting parts 12 are fixedly arranged; the two tensioning wheels 13 are respectively arranged on the inner side of the two conveyor belts 2; one end of the connecting part 11 is equipped with a tensioning wheel 13, and the other end is rotatably arranged on the mounting part 12, so that the two tensioning wheels 13 can move away from or close to each other; the two ends of the first elastic element 10 are respectively connected to the ends of the two connecting parts 11 on which the tensioning wheels 13 are installed, so that the two tensioning wheels 13 apply clamping forces of opposite direction and the same magnitude to the parts of the two conveyor belts 2 facing or close to the front end of the debonding support strip 20. When the object to be processed has not entered, the first elastic element 10 is in a certain tensile state, so that the tension wheel 13 is close to the inner side of the conveyor belt 2, and there is always a certain gap between the two conveyor belts 2. When the object to be processed enters, the first elastic element 10 is stretched longer and always remains within the elastic deformation of the tension spring, which can provide appropriate tension force to the object to be processed and achieve the tensioning and positioning function for objects of different sizes.

[0030] The structure is simple and compact, with few parts and easy assembly, using only one first elastic element 10 to drive both tensioning wheels 13 simultaneously. The continuous and moderate tension provided by the first elastic element 10 can prevent the conveyor belt 2 from slipping due to being too loose or wearing due to being too tight. Its buffering characteristics can also reduce the crushing damage to the workpiece. The clamping force is controlled by the elastic element to prevent the internal structure of the workpiece from breaking due to excessive clamping.

[0031] Example 2 like Figure 1-6 As shown, this embodiment discloses a laparotomy and deboning machine, including a frame 14. The frame 14 is equipped with a laparotomy device 17, a deboning device 18, and a conveying device as described in Embodiment 1. The conveying device is used to convey the object to be processed from a first end to a second end. The laparotomy device 17 is disposed in the conveying channel of the conveying device and is used to perform laparotomy on the object to be processed. The deboning device 18 is disposed in the conveying channel downstream of the laparotomy device 17 and is used to debon the object to be processed after laparotomy.

[0032] In this embodiment, the blotting and deboning machine uses a conveying device to transport the material to be processed from the first end to the second end, passing sequentially through the blotting device 17 and the deboning device 18 located in the conveying channel. The blotting device 17 is used to blotting the material to be processed; the deboning device 18 is used to debon the material after blotting. The machine has a compact structure and strong adaptability, and can realize continuous integrated operation of clamping, conveying, blotting, and deboning. It solves the problem of slippage and displacement of the material to be processed in a high-viscosity environment, ensuring both conveying stability and avoiding meat compression damage, thus ensuring the meat quality requirements of the slaughtered material.

[0033] In one specific embodiment, the device also includes a feeding hopper 15 and a feeding pipe. The feeding hopper 15 is mounted on the frame 14. The discharge end of the feeding hopper 15 is connected to the inlet of the feeding pipe, and the outlet of the feeding pipe faces the first end of the conveying channel to supply the material to be processed to the conveying device.

[0034] It also includes a seppuku device 17, which is located in the conveying channel upstream of the deboning support strip 20 and is used to perform seppuku on the object to be processed. The seppuku device 17 includes a second motor and a seppuku knife 19. The output shaft of the second motor is connected to the seppuku knife 19, which extends into the conveying channel to perform seppuku on the object to be processed.

[0035] In one embodiment, a clamping device is also included, comprising a deboning support strip 20, a deboning pressure strip 21, and an elastic support assembly 22. The deboning support strip 20 is disposed downstream of the ventilation device 17 along the conveying direction and is used to open the ventilated material to be processed. The deboning pressure strip 21 is disposed above the deboning support strip 20 and is used to provide pressure to the material to be processed toward the deboning support strip 20. The elastic support assembly 22 is used to elastically support the deboning pressure strip 21 and enable the deboning pressure strip 21 to elastically float relative to the deboning support strip 20 in a direction parallel to the conveying plane and perpendicular to the conveying direction, so as to accommodate materials of different sizes.

[0036] The deboning support strip 20 is used to open the laparotomized specimen and transfer it to the deboning device 18 for subsequent deboning. The deboning pressure strip 21 is used to provide pressure to the specimen towards the deboning support strip 20 to ensure that the laparotomized specimen maintains a stable opening, consistent plane, and synchronous transmission in the deboning area, creating a controllable operating environment for the subsequent deboning process. The elastic support component 22 is used to elastically support the deboning pressure strip 21 and can automatically adjust its upper and lower position according to the thickness of the specimen. Before the specimen enters the deboning pressure strip 21 and the deboning support strip 20, there is a certain gap between them to allow the specimen to enter. After the specimen enters the deboning support strip 20, the deboning pressure strip 21 always maintains a close fit with the specimen under the action of the elastic support component 22, and always maintains a moderate and uniform downward pressure, thereby achieving the core functions of stable pressing and conformal fitting without damaging the specimen tissue.

[0037] In one embodiment, the bottom of the deboning strip 21 is provided with a guide groove 33, which extends along the conveying direction. The cross section of the guide groove 33 on the vertical plane perpendicular to the conveying direction is arc-shaped to conform to the spine curve of the object to be processed.

[0038] The guide channel 33 can conform to the spine curve of the object to be processed, preventing the object from deviating from the conveying channel during the conveying process and ensuring the stable execution of the deboning operation.

[0039] In one embodiment, the elastic support assembly 22 includes an optical axis 23, a slider 24, a limiting part 25, and a second elastic element 26; the optical axis 23 is vertically arranged; the slider 24 is fixedly connected to the bone removal strip 21 and slidably sleeved on the optical axis 23; the limiting part 25 is arranged on the optical axis 23 and located above the slider 24; the second elastic element 26 is sleeved on the optical axis 23 and located between the slider 24 and the limiting part 25 to provide elastic support for the bone removal strip 21.

[0040] The limiting part 25 is set on the optical axis 23 and located above the slider 24 to prevent the slider 24 from falling out; the second elastic element 26 is sleeved on the optical axis 23 and located between the slider 24 and the limiting part 25. The slider 24 is fixedly connected to the debonding strip 21 and slidably sleeved on the optical axis 23. Before the workpiece enters the debonding strip 21 and the debonding support strip 20, the slider 24, under the elastic force of the second elastic element 26, creates a certain gap between the debonding strip 21 and the debonding support strip 20 to allow the workpiece to enter; the workpiece enters the debonding support strip, the debonding strip contacts the workpiece, and is lifted upward by the reaction force of the workpiece, driving the slider to slide upward along the vertical optical axis; the slider moves upward and squeezes the second elastic element, the second elastic element is compressed and stores elastic potential energy, at this time the second elastic element applies reverse pressure to the slider and the debonding strip, forming a continuous elastic clamping force, allowing the debonding strip to fit tightly against the workpiece, ensuring the stability of the debonding operation.

[0041] The optical axis 23 and the slider 24 form a precision linear motion pair, providing precise vertical guidance for the deboning strip 21, avoiding swaying and jamming, and ensuring that the deboning strip 21 is always parallel to the deboning support strip 20; the second elastic element 26 is in a compressed state between the slider 24 and the limiting part 25, providing linear restoring force; the limiting part 25 directly abuts against the slider 24 when the elastic element is over-compressed, preventing the strip from coming out when there is no load.

[0042] In one specific embodiment, the deboning support strip 20 has two inclined surfaces on the side near the deboning pressure strip 21 and the side near the first end. The two inclined surfaces are distributed sequentially and symmetrically along the direction perpendicular to the conveying surface of the conveyor belt 2. The two inclined surfaces gradually open outward along the direction away from the deboning pressure strip 21, and the included angle of the inclined surfaces is 60°. The two inclined surfaces are used to support the inner sides of the abdomen of the object to be processed after the laparotomy. The two inclined surfaces of the deboning support strip 20 naturally fit with the inner sides of the abdomen of the object to be processed after the laparotomy, forming a stable support reference. The deboning device 18 includes a third motor and two symmetrically arranged deboning blade discs 27. The third motor drives the deboning blade discs 27 to rotate. The two deboning blades 27 gradually open outwards along the direction away from the deboning strip 21, and the two deboning blades 27 are set parallel to the two inclined planes respectively, so that the cutting direction of the blades is consistent with the direction of the bone-meat interface on the inner side of the abdominal wall. The blades can cut along the inclined planes, accurately separating the attachment points of bones and muscles, avoiding cutting off the correct angle, cutting through, or leaving bone and meat residue. The two deboning blades 27 are located between the two planes of the two inclined planes, and the end of the two deboning blades 27 that is close to each other protrudes from the deboning support strip 20. The working edge of the blades extends beyond the support surface of the support strip, and can actively enter the bone-meat junction, ensuring thorough deboning and preventing excessive cutting that could damage the back skin or internal organs.

[0043] In one specific embodiment, the deboning support strip 20 is provided with a notch 28 to ensure that the cut bone falls off. The notch 28 is located on the side of the deboning support strip 20 near the second end, and the notch 28 can increase the space for deboning, making it convenient to perform the deboning operation.

[0044] In one specific embodiment, a bone scraping structure 29 is also included. The bone scraping structure 29 is located downstream of the bone removal device 18 in order to scrape off the internal organs of the material to be processed after bone scraping and to ensure the processing quality of the material to be processed.

[0045] like Figure 7 As shown, the internal groove of the bone scraping structure 29 is n-shaped and is fixed at an angle on the frame, using the top arc to scrape away the internal organs and the bones that have not fallen off.

[0046] In one embodiment, a material collection device is also included, which is disposed at the second end of the conveying device for collecting the deboned material to be processed.

[0047] In one specific embodiment, the collection device includes a collection bin 30 located downstream of the second end to facilitate the collection of processed materials.

[0048] In one embodiment, a spraying device is also included, which is used to spray the conveying channel and the material to be processed therein toward the conveying channel.

[0049] The spray washing device includes a water tank 31, a water pipe 32, and a nozzle 16. The water tank 31 is installed inside the frame 14. The water pipe 32 uses a water pump to spray the water from the water tank 31 through the nozzle 16 to wash the conveying channel, cleaning the mucus and blood throughout the slaughtering process to ensure hygiene and improve safety.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
