Description

Technical Field

[0001] This invention relates to the field of fish processing technology, and in particular to a descaling and gutting device for fish processing. Background Technology

[0002] Fish processing is a crucial step in aquatic food production, with scaling, gutting, and evisceration being the core pre-processing steps. Traditional fish processing relies heavily on manual labor, which suffers from high labor intensity, low processing efficiency, and difficulty in standardizing hygiene. Furthermore, manual processing is prone to defects such as incomplete scaling, misaligned gutting, and residual evisceration due to differences in fish size and shape, all of which affect the quality of the finished product.

[0003] Existing automated fish processing equipment generally suffers from poor adaptability and limited functionality. Most equipment can only perform single scaling or gutting operations and cannot complete continuous processing. At the same time, the processing components of the equipment are mostly fixed structures, which make it difficult to adapt to fish of different sizes and thicknesses, and can easily cause damage to the fish. In addition, the waste collection and simultaneous cleaning are not well-integrated, and fish scales, viscera and other waste are easily scattered and pollute the processing environment, increasing subsequent cleaning costs and making it difficult to meet the needs of large-scale and standardized aquatic product processing.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of the present invention, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] To address the shortcomings or defects of the existing technology, a descaling and gutting device for fish processing is provided. This device achieves integrated and continuous operation of descaling, gutting, and eviscerating, adaptable to fish of different sizes, and offers high processing efficiency and excellent cleaning results.

[0006] The objective of this invention is achieved through the following technical solutions.

[0007] A fish processing descaling and gutting device includes a device support, on which a descaling component and a gutting component are sequentially arranged along the fish conveying direction.

[0008] The descaling assembly includes symmetrically arranged brush rollers that also serve as fish transport components during the descaling process, an auxiliary scraping roller for rotating and scraping scales, a fixed base, a sliding rod, and a spring. The fixed base is fixed above the device support, the sliding rod passes through the fixed base, and the spring is fitted onto the sliding rod. The brush rollers are slidably connected to the sliding rod. The fixed base, the sliding rod, and the spring constitute an elastic adjustment mechanism that adaptively adjusts the spacing between the brush rollers according to the width of the fish. When the brush rollers rotate, they scrape off the fish scales and, through friction, drive the fish forward.

[0009] The gutting assembly includes a V-shaped support structure for supporting the fish belly, a conveyor belt for transporting the fish body, a gutting knife for rotating and cutting the fish belly, a second fixed seat, a connecting rod, a slider, and a spring. The V-shaped support structure is located inside the device support to support the fish body. The gutting knife penetrates the inside of the device support and is driven to rotate by a drive motor. The second fixed seat is fixed to the top of the device support and has a connecting rod inside. The slider is slidably connected to the connecting rod, and the spring is located on the slider. The second fixed seat, the connecting rod, the slider, and the spring constitute an elastic adjustment mechanism that allows the gutting assembly to adapt to fish bodies of different thicknesses. As the conveyor belt transports the fish body, the gutting knife rotates to cut the passing fish body.

[0010] In the aforementioned fish processing descaling and gutting device, the descaling component further includes a speed control structure, which includes a drive motor one and a drive motor two with independently adjustable rotation speeds, and a bevel gear transmission device. The drive motor one drives the brush roller to rotate to remove scales from both sides of the fish body, and the drive motor two drives the auxiliary scraping roller to rotate to remove fish scales through the bevel gear transmission device.

[0011] In the aforementioned fish processing descaling and gutting device, the descaling assembly further includes an inlet, a conveyor wheel, and a tray. The conveyor wheel is located at the inlet to guide the fish body in, and the tray supports the fish body from below, working in conjunction with the brush roller to achieve conveying.

[0012] In the aforementioned fish processing descaling and gutting device, the gutting assembly further includes a drive motor three, a transmission gear, a driven wheel, and a transmission roller disposed on the inner side of the device support. The output shaft of the drive motor three is provided with a connecting gear. The transmission gear meshes with the connecting gear and is located on the side of the drive motor three. The driven wheel gear meshes with the side of the transmission gear. A transmission roller is disposed at the bottom of the driven wheel. The transmission roller meshes with a conveyor belt to drive the conveyor belt to transport the fish.

[0013] In the aforementioned fish processing descaling and gutting device, a drive motor is provided at the bottom of the device support, and the drive motor drives the gutting knife to rotate to gut the fish.

[0014] In the aforementioned fish processing descaling and gutting device, the gutting knife includes a central cylinder and multiple blades circumferentially distributed on its outer surface.

[0015] In the aforementioned fish processing descaling and gutting device, the V-shaped support structure, together with the height-adjustable clamping plate, positions and fixes the fish body.

[0016] In the aforementioned fish processing descaling and gutting device, a drive motor four is provided at the bottom of the device support and on the side of the drive motor five. The output shaft of the drive motor four is connected to a cleaning disc, and the cleaning disc includes a spoon-handle-shaped blade for removing the internal organs of the gutted fish.

[0017] The fish processing descaling and gutting device also includes a spray assembly located inside the device support, which has two outlet ends. One outlet end is located above the descaling assembly for rinsing fish scales, and the other outlet end is aligned with the cleaning plate for rinsing the abdominal cavity of the fish.

[0018] The fish processing descaling and gutting device also includes a waste bin located below the descaling assembly to collect the removed fish scales.

[0019] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention integrates the scaling, gutting, evisceration, and simultaneous spray cleaning processes through an integrated design, achieving continuous and automated pre-processing of fish, significantly improving processing efficiency, reducing manual labor intensity, and avoiding the problem of uneven quality caused by manual operation. Employing multiple sets of elastic adaptive structures, the scaling component automatically adjusts the brush roller spacing via slide rods and springs, while the gutting component adapts to fish of different thicknesses using sliders and springs. Combined with a V-shaped support structure and tray positioning, it can process fish of various sizes, avoiding damage to the fish. Simultaneously, the combined structure of dual-motor independent speed-controlled scaling, multi-blade rotary gutting, and spoon-handle-shaped blade evisceration ensures thorough scaling, precise gutting, and clean evisceration, significantly improving the quality of the processed fish product.

[0032] To facilitate understanding of the embodiments of the present invention, the following will provide further explanation and description with reference to the accompanying drawings and several specific embodiments, and the accompanying drawings do not constitute a limitation on the embodiments of the present invention.

[0033] To better understand, such as Figures 1 to 5 As shown, a fish processing descaling and gutting device includes a device support 1. A descaling component 4 and a gutting component 5 are sequentially arranged on the device support 1 along the fish conveying direction.

[0034] The descaling assembly 4 includes symmetrically arranged brush rollers 404 that also serve as fish transport components during the descaling process, an auxiliary speed control plate 408 for rotating and scraping scales, a fixed base 409, a slide rod 410, and a spring 411. The fixed base 409 is fixed above the device support 1. The slide rod 410 passes through the fixed base 409, and the spring 411 is sleeved on the slide rod 410. The brush rollers 404 are slidably connected to the slide rod 410. The fixed base 409, the slide rod 410, and the spring 411 constitute an elastic adjustment mechanism that adaptively adjusts the spacing between the brush rollers 404 according to the width of the fish. When the brush rollers 404 rotate, they scrape off the fish scales and drive the fish forward through friction. They are positioned between two sets of brush rollers 404 to adjust the feeding speed of the fish.

[0035] The gutting assembly 5 includes a V-shaped support structure for supporting the fish belly, a conveyor belt 505 for conveying the fish body, a gutting knife 513 for rotating and cutting the fish belly, a second fixed seat 506, a connecting rod 509, a slider 507, and a spring 508. The V-shaped support structure is located inside the device support 1 to support the fish body. The gutting knife 513 penetrates the inside of the device support 1 and is driven to rotate by a drive motor. The second fixed seat 506 is fixed to the top of the device support 1 and has a connecting rod 509 inside it. The slider 507 is slidably connected to the connecting rod 509. The spring 508 is located on the slider 507. The second fixed seat 506, the connecting rod 509, the slider 507, and the spring 508 constitute an elastic adjustment mechanism that allows the gutting assembly 5 to adapt to fish bodies of different thicknesses. As the conveyor belt 505 conveys the fish body, the gutting knife 513 rotates to cut the passing fish body.

[0036] In a preferred embodiment of the fish processing descaling and gutting device, the descaling component 4 further includes a speed control structure, which includes a drive motor 403 with independently adjustable rotation speed, a drive motor 406, and a bevel gear transmission device 407. The drive motor 403 drives the brush roller 404 to rotate to remove scales from both sides of the fish body, and the drive motor 406 drives the auxiliary speed control plate 408 through the bevel gear transmission device 407 to adjust the feeding speed of the fish body.

[0037] In a preferred embodiment of the fish processing descaling and gutting device, the descaling assembly 4 further includes an inlet 401, a conveyor wheel 402, and a tray 405. The conveyor wheel 402 is located at the inlet 401 to guide the fish body into the inlet, and the tray 405 supports the fish body from below, and works with the brush roller 404 to achieve conveying.

[0038] In a preferred embodiment of the fish processing descaling and gutting device, the gutting assembly 5 further includes a drive motor 501, a transmission gear 502, a driven wheel 503, and a transmission roller 504 disposed on the inner side of the device support 1. The output shaft of the drive motor 501 is provided with a connecting gear. The transmission gear 502 meshes with the connecting gear and is located on the side of the drive motor 501. The driven wheel 503 meshes with the side of the transmission gear 502. The bottom of the driven wheel 503 is provided with a transmission roller 504. The transmission roller 504 meshes with the conveyor belt 505 to drive the conveyor belt 505 to transport the fish.

[0039] In a preferred embodiment of the fish processing descaling and gutting device, a drive motor 512 is provided at the bottom of the device support 1, and the drive motor 512 drives the gutting knife 513 to rotate to gut the fish.

[0040] In a preferred embodiment of the fish processing descaling and gutting device, the gutting knife 513 includes a central cylinder and a plurality of blades circumferentially distributed on its outer surface.

[0041] In a preferred embodiment of the fish processing descaling and gutting device, the V-shaped support structure, together with the height-adjustable clamping plate, positions and fixes the fish.

[0042] In a preferred embodiment of the fish processing descaling and gutting device, a drive motor 510 is provided at the bottom of the device support 1 and on the side of the drive motor 512. The output shaft of the drive motor 510 is connected to a cleaning disc 511. The cleaning disc 511 includes a spoon-handle-shaped blade for removing the internal organs of the gutted fish.

[0043] In a preferred embodiment of the fish processing descaling and gutting device, a spray assembly 3 located inside the device support 1 is also included. The spray assembly 3 has two outlet ends. One outlet end is located above the descaling assembly 4 for rinsing fish scales, and the other outlet end is aligned with the cleaning disc 511 for rinsing the abdominal cavity of the fish.

[0044] In a preferred embodiment of the fish processing descaling and gutting device, a waste bin 2 is provided below the descaling assembly 4 to collect the removed fish scales.

[0045] In one embodiment, a fish processing descaling and gutting device includes: a device support 1, on which a descaling component 4 and a gutting component 5 are sequentially arranged along the fish conveying direction, respectively used for descaling the fish and gutting the fish to clean the internal organs; a spray component 3 and a waste bin 2 are also provided on the inner side of the device support 1.

[0046] The descaling assembly 4 includes symmetrically arranged brush rollers 404, auxiliary speed control plate 408, fixed base 409, slide bar 410, spring 411, and speed control structure. The fixed base 409 is fixed above the device support 1. The slide bar 410 passes through the fixed base 409. The spring 411 is sleeved on the outside of the slide bar 410 to realize adaptive adjustment of the spacing of the brush rollers 404. The brush rollers 404 also serve as a conveying component during the descaling process of fish.

[0047] With the device bracket 1 as the whole support, the fish body passes through the descaling component 4 and the gutting component 5 in sequence along the conveying direction to complete continuous processing. In the descaling component 4, the symmetrical brush rollers 404 and the auxiliary speed control plate 408 work together to descale. The fixed seat 409, the slide rod 410, and the spring 411 form an elastic adjustment mechanism. The brush rollers 404 can slide along the slide rod 410. The spring 411 provides elastic force, so that the spacing of the brush rollers 404 is automatically adjusted with the width of the fish body. When the brush rollers 404 rotate, they scrape off the fish scales and drive the fish body forward through friction. The spray component 3 washes synchronously, and the waste bin 2 collects the fish scales and waste.

[0048] The speed control structure includes a first drive motor 403, a second drive motor 406, and a bevel gear transmission device 407. The second drive motor 406 rotates at high speed via the bevel gear transmission device 407 and an auxiliary speed control plate 408. The first drive motor 403 drives the brush roller 404 to rotate for removing scales from the fish. The first drive motor 403 directly drives the brush roller 404 to rotate, completing the descaling of the fish according to the conveying speed. The second drive motor 406 is driven by the bevel gear transmission device 407 to reverse the transmission. The two motors can independently adjust their speeds.

[0049] The descaling assembly 4 is also equipped with an inlet 401, a conveyor wheel 402, and a tray 405. The tray 405 supports the fish and is transported by rotating with the brush roller 404. The conveyor wheel 402 is located at the inlet 401 and is used to work with the brush roller 404 to stably feed the fish. The fish is put into the inlet 401, and the rotating conveyor wheel 402 smoothly guides the fish into the descaling assembly 4. The tray 405 supports the fish from below and, together with the rotating brush roller 404 above, prevents the fish from shifting or sinking, so that the fish is stably transported along a fixed trajectory.

[0050] Waste bin 2 is located below descaling component 4 and is used to collect the removed scales. The fish scales scraped off by descaling component 4 fall into waste bin 2 below under the spray component 3, realizing immediate centralized collection of fish scales.

[0051] The gutting assembly 5 includes a V-shaped support structure, a conveyor belt 505, a gutting knife 513, a second fixing seat 506, a slider 507, a spring 508, and a connecting rod 509. The V-shaped support plate is located inside the device bracket 1 to support the fish body and is fixed to the fish body by cooperating with a height-adjustable clamping plate located above. The gutting knife 513 penetrates the interior of the device bracket 1. The second fixing seat 506 is fixedly connected to the top of the device bracket 1. The connecting rod 509 is located inside the second fixing seat 506. The slider 507 is slidably connected to the outer surface of the connecting rod 509. The spring 508 is located on the side of the slider 507 and on the outer surface of the connecting rod 509 to cooperate with the gutting assembly 5 to adapt to fish bodies of different thicknesses.

[0052] After the fish enters the gutting assembly 5, the V-shaped support structure supports the fish belly, the pressure plate fixes the fish body, the conveyor belt 505 transports the fish body, and the gutting knife 513 rotates to cut the fish belly open. The fixed seat 506, the slider 507, the spring 508, and the connecting rod 509 constitute an elastic adjustment mechanism. The slider 507 slides along the connecting rod 509, and the spring 508 provides elastic force, so that the conveyor belt 505 can adapt to the thickness of the fish body.

[0053] The gutting assembly 5 also includes a drive motor 501, a transmission gear 502, a driven wheel 503, and a transmission roller 504. The drive motor 501 is located inside the device bracket 1. The output shaft of the drive motor 501 is equipped with a connecting gear. The transmission gear 502 is meshed with the side of the drive motor 501. The driven wheel 503 is meshed with the side of the transmission gear 502. The bottom of the driven wheel 503 is equipped with a transmission roller 504. The transmission roller 504 meshes with the conveyor belt 505 and is used to drive the conveyor belt 505 to transport the fish.

[0054] The drive motor 501 outputs power, which drives the transmission gear 502 to rotate via the connecting gear. The transmission gear 502 drives the driven wheel 503 to rotate, and the driven wheel 503 drives the transmission roller 504 to rotate. The transmission roller 504 meshes with the conveyor belt 505 to achieve uniform speed transport of the fish.

[0055] The bottom of the device support 1 is equipped with a drive motor 512. The drive motor 512 and the guillotine 513 transmit power to each other. The drive motor 512 drives the guillotine 513 to rotate, thereby completing the gutting of the fish. The drive motor 512 is fixed to the bottom of the device support 1 and directly outputs power to drive the guillotine 513 to rotate continuously, cutting the abdomen of the fish and completing the automated gutting.

[0056] At the bottom of the device bracket 1 and on the side of the drive motor 512, there is a drive motor 510. The output shaft of the drive motor 510 is connected to a cleaning disc 511. The cleaning disc 511 is a spoon-handle type blade used to remove the internal organs of the fish after it has been gutted. After the fish has been gutted, the drive motor 510 drives the spoon-handle type cleaning disc 511 to rotate. The cleaning disc 511 extends into the fish's belly and quickly removes the internal organs, mucous membranes and other organs by scraping and peeling.

[0057] A spray assembly 3 is installed above the device support 1. The spray assembly 3 has two outlets. One outlet is aligned with the cleaning disc 511 and is used to rinse the inside of the fish and remove residual impurities in the abdominal cavity. The other outlet is located above the descaling assembly 4 and is used to assist in rinsing the fish during the scale removal process. The spray assembly 3 is connected to an external water source and the two outlets spray water simultaneously: the outlet above the descaling assembly 4 sprays water to wash off the scales during scale removal, and the outlet aligned with the cleaning disc 511 sprays water to rinse away blood and debris from the fish's abdomen during the cleaning of internal organs, in conjunction with the cleaning disc 511 for deep cleaning.

[0058]

[0059] Furthermore, the descaling assembly employs an elastic adaptive mechanism composed of sliders and lead screws, enabling the symmetrically arranged brush rollers to automatically adjust their spacing according to the fish's width. This ensures sufficient contact with the fish's surface for efficient scale removal while avoiding squeezing damage caused by rigid clamping. Combined with an independently speed-controlled dual-motor drive system, drive motor one drives the brush rollers for basic descaling and conveying, while drive motor two, via a bevel gear transmission device, rotates an auxiliary speed control plate to adjust the feed. This allows for flexible adjustment of descaling force and speed based on the scale adhesion strength of different fish species, achieving a thorough and uniform descaling effect. The gutting assembly uses a V-shaped support structure with a height-adjustable pressure plate for stable positioning of the fish. Combined with a vertical elastic adjustment mechanism consisting of sliders, springs, and connecting rods, the relative position between the conveyor belt and the gutting knife automatically adjusts according to the fish's thickness, ensuring the gutting knife always precisely cuts along the fish's belly centerline, avoiding off-center or missed cuts. The rotary gutting knife operates continuously under the drive of drive motor five, producing clean cuts, high efficiency, and is suitable for fish of different sizes. The spoon-handled cleaning disc, working in tandem with a directional spray system, immediately extends into the fish's abdomen after gutting. It rotates and scrapes away the viscera and mucous membranes, while the spray system simultaneously jets water from the cleaning disc's outlet, flushing out blood, debris, and remaining organs from the abdominal cavity. This integrated approach to efficient viscera removal and initial cavity cleaning significantly reduces human intervention and the risk of secondary contamination. The integrated layout of the waste bin and spray system enables real-time waste collection and environmental cleanliness during processing: during the descaling stage, the sprayed water flushes detached scales into the waste bin below, preventing splash contamination. The entire process is closed and orderly, meeting food processing hygiene standards. In summary, the various technologies work together to achieve the goal of continuous fish pretreatment that is "adaptive, highly efficient, low-damage, and highly clean."
