Description

Technical Field

[0001] This invention relates to the field of fish scale removal technology, and in particular to a high-efficiency fish scale removal device and a fish scale cleaning method. Background Technology

[0002] In the mechanized descaling process of fish processing, the body contours of the fish being processed exhibit non-standardized curved surface variations. Existing rigid scraping and conveying mechanisms typically operate along fixed or roughly pre-set spatial trajectories. Due to the lack of a dynamic spatial accommodation and fitting mechanism for non-standard shapes, localized stress concentrations and contact blind spots easily occur between the fish skin and the working components, leading to uneven descaling and surface damage. Simultaneously, scraped scales and fish secretions remain in the operating space, interacting with the heat generated by mechanical friction. For power output components located inside or at the top of the equipment, this enclosed, humid, and hot environment easily causes heat accumulation. Under long-term operation, the physical vibrations and heat retention generated by the independent stacking of multiple components deteriorate the operating conditions of the power mechanism. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of contact blind spots and local stress concentration caused by the mismatch between the non-standard curved surface shape of the object being processed and the rigid working trajectory, as well as the resulting problems of waste space retention and heat accumulation in power components in the prior art. The invention proposes an efficient fish scale removal device and a fish scale cleaning method.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A high-efficiency fish scale removal device includes a frame, the top of which is fixedly connected to a panel; The panel has a main drain hole in the middle, and an inclined discharge plate is fixed to one end of the main drain hole. The panel also has drain side holes on both sides of the top. Both sides of the sewage discharge side hole have interconnected strip-shaped sliding holes on their inner walls. A sliding block is slidably embedded in the strip-shaped sliding hole, and a mounting support plate is fixedly connected to the top of the sliding block. The top of the mounting support plate is provided with a conveying component, a scraping component, and a cleaning component, with the conveying component and the cleaning component located on both sides of the scraping component; The frame is equipped with an adjustment assembly for adjusting the gap between the two mounting support plates to accommodate fish of different sizes. The fish scales scraped off by the scraping component are discharged through the main drain hole and the side drain hole to avoid the accumulation of fish scales affecting the operation of the equipment.

[0005] In one possible design, the conveying assembly includes two symmetrically arranged drive shafts that are rotatably supported on the top of a mounting support plate; The outer wall of the drive shaft is fixedly fitted with a conveyor roller II, and the outer walls of the two conveyor rollers II are fitted with the same conveyor belt I. Multiple rubber strips are fixed to the outer wall of the conveyor belt I. These rubber strips can increase the friction with the fish and adapt to the size of the fish through slight deformation, ensuring stable transport of the fish.

[0006] In one possible design, the scraping assembly includes two rotating rods rotatably supported on the top of a mounting support plate; The outer wall of the rotating rod is fixedly fitted with a scraping shaft, and the outer wall of the scraping shaft is fixedly connected with multiple scraping protrusions; Synchronous pulleys are fixedly fitted on the outer walls of the rotating rods. The outer walls of the two synchronous pulleys are fitted with the same synchronous belt, which can drive the two scraping shafts to rotate synchronously, thereby improving the thoroughness of fish scale removal.

[0007] In one possible design, the cleaning assembly includes two symmetrically arranged rotating shafts II that are rotatably supported on the top of the mounting support plate; The outer wall of the rotating shaft II is fixedly fitted with a conveying roller I, and the outer wall of the conveying roller I is fitted with multiple conveyor belts II. Multiple rubber blocks are fixedly connected to the outer wall of the conveyor belts II, and gaps are left between the multiple conveyor belts II. The top of the mounting support plate is rotatably supported by multiple mounting cylinders. Multiple bristles are fixed to the outer wall of the mounting cylinders. The bristles can extend from the gaps between the conveyor belts II to beat and clean the surface of the fish, preventing the fish scales from sticking together.

[0008] In one possible design, a rotating shaft I is fixedly connected to the top of the mounting cylinder, and a driven gear is fixedly sleeved on the outer wall of the rotating shaft I. One of the rotating shafts II has a drive gear fixedly fitted on its outer wall, and multiple driven gears mesh with each other. The drive gear meshes with the nearest driven gear, which can drive multiple mounting cylinders to rotate synchronously.

[0009] In one possible design, the adjustment assembly includes a bidirectional lead screw that rotates through the interior of the frame; A rectangular plate is fixedly connected to the bottom of the sliding block, and the bidirectional lead screw is threaded through the two rectangular plates. A handwheel is fixedly connected to one end of the bidirectional lead screw. Turning the handwheel will drive the bidirectional lead screw to rotate, which in turn will cause the two rectangular plates to move in opposite directions, adjusting the distance between the two mounting support plates.

[0010] In one possible design, a protective cover is fixed to the top of the frame, and a clearance hole is provided at the bottom of the protective cover, through which the fish can be fed into the conveying assembly. A rectangular cavity is provided on one side of the top of the protective cover, and multiple horizontal holes are provided at the bottom of the rectangular cavity, which are connected to the clearance holes; Multiple mounting plates are slidably embedded in the inner wall of the bottom of the rectangular cavity, and servo motor I, servo motor II and servo motor III are respectively fixed to the top of the multiple mounting plates.

[0011] In one possible design, the output shaft of the servo motor III is fixedly connected to the top of one of the drive shafts for driving the drive shaft to rotate; The output shaft of the servo motor II is fixedly connected to the top of one of the rotating rods and is used to drive the rotating rod to rotate. The output shaft of the servo motor I is fixedly connected to the top of one of the rotating shafts II, and is used to drive the rotating shaft II to rotate.

[0012] In one possible design, a maintenance plate is hinged to the top of the rectangular cavity, a handle is fixed to the top of the maintenance plate, multiple heat dissipation holes are opened inside the maintenance plate, and multiple support rollers are rotatably connected between the inner walls of the two sides of the frame. The inspection panel can be opened with a handle, making it easy to inspect and maintain servo motors I, II, and III. The heat dissipation holes can dissipate the heat generated by the servo motors in a timely manner, preventing the motors from overheating and being damaged.

[0013] A fish scale cleaning method based on the above-mentioned high-efficiency fish scale removal equipment includes the following steps: S1: Adjust the spacing. According to the size of the fish to be processed, turn the handwheel to drive the double-sided lead screw to rotate. The double-sided lead screw drives the two rectangular plates to move in opposite directions, which in turn drives the two mounting support plates to move synchronously. After adjusting to the spacing that fits the fish, stop turning the handwheel. S2: The equipment is started, and servo motors I, II, and III are turned on. Servo motor III drives the drive shaft to rotate, which drives conveyor belt I to run. Servo motor II drives the rotating rod to rotate, which drives the two scraping shafts to rotate synchronously through the synchronous pulley and synchronous belt. Servo motor I drives the rotating shaft II to rotate, which drives conveyor belt II to run. At the same time, the drive gear drives the driven gear to rotate, which drives multiple mounting cylinders and brushes to rotate synchronously. S3: Fish conveying and scaling. The fish to be processed is put into the conveyor belt I through the clearance hole at the bottom of the protective cover. The rubber strip on the conveyor belt I fits the fish and drives the fish towards the scraping component. The scaling protrusion on the scaling shaft rotates synchronously to completely scrape off the fish scales on the surface of the fish. The scraped fish scales are discharged through the main drain hole and the side drain hole on the panel. S4: Fish cleaning. After the fish scales are scraped off, the fish body is transported to the cleaning component by conveyor belt I. Conveyor belt II drives the fish body to continue moving. At the same time, rotating bristles extend from the gaps between conveyor belts II to knock and clean the residual fish scales adhering to the surface of the fish body, ensuring that the surface of the fish body is clean. S5: Discharge and shutdown. After cleaning, the fish body is discharged through the inclined discharge plate, completing the fish scale cleaning operation. After the operation is completed, all servo motors are turned off. The inspection panel can be opened by the handle to inspect and maintain the equipment and servo motors.

[0014] In this application, during use, the fish is put into the space between the two conveyor belts I through the clearance hole, the servo motor III is started, the output shaft of the servo motor III drives the drive shaft to rotate, the drive shaft drives the conveyor roller II to rotate, the conveyor roller II drives the outer conveyor belt I to move forward, the conveyor belt I drives the inner fish to move forward, and the rubber strip can increase the friction and can also adapt to the size of the fish through slight deformation. Furthermore, servo motor II can be started. The output shaft of servo motor II drives one of the scraping shafts to rotate, and drives the other scraping shaft to rotate through the external synchronous belt and synchronous pulley. The scraping shaft drives the scraping protrusions on the outer wall to rotate, and the scraping protrusions scrape off the fish scales. The fish scales are scraped off by the two sets of scraping protrusions. The fish rolls forward on multiple support rollers below. The gap between the multiple support rollers is only for the fish scales to pass through, ensuring that the fish is transported forward normally. After the fish scales are removed, servo motor I is started. The output shaft of servo motor I drives rotating shaft II to rotate, rotating shaft II drives conveyor roller I to rotate, conveyor roller I drives conveyor belt II to transport the fish forward, and conveyor belt II can help the fish continue to be transported forward, and finally discharged outward through the inclined discharge plate. The synchronous rotating shaft II can drive the drive gear to rotate, the drive gear drives multiple driven gears to rotate in sequence, the driven gears drive the rotating shaft I to rotate, the rotating shaft I drives the mounting cylinder to rotate, and the mounting cylinder drives the brush to rotate. Since there are gaps between the multiple conveyor belts II, the brush bristles extend out from the gaps and continuously beat the fish scales in both forward and reverse directions to prevent the fish scales from falling off and continuing to stick to the fish, thus improving the cleaning effect. Furthermore, during use, the handwheel can be turned as needed, which drives the double-acting screw to rotate. The double-acting screw then moves the two outer rectangular plates laterally. The rectangular plates cause the sliding block to slide inside the strip-shaped sliding hole. The sliding block then moves the upper mounting support plate laterally. At this time, the distance between the two mounting support plates changes, thus adapting to fish of different sizes.

[0015] Beneficial Effects: This application constructs a dynamic accommodating space for changes in fish body shape through the horizontal and vertical spatial arrangement rules of multiple components. The adjustment components utilize bidirectional lead screws and sliding blocks to change the spacing of the mounting support plates on both sides, determining the width of the basic conveying channel based on the initial contour of the fish body. The rubber strips attached to the periphery of conveyor belt I in the conveying component undergo slight deformation, conforming to the curved surface characteristics of different body shapes, establishing a flexible contact transition area, reducing local stress concentration, and maintaining the material conveying posture.

[0016] The scraping component uses the synchronous reverse action of dual scraping shafts to peel off the fish's skin within a confined space. The cleaning component uses the reserved gap between conveyor belts II as the action penetration path, with bristles moving through this gap to physically strike the residual scales attached to the body surface, avoiding a decrease in surface cleanliness caused by secondary adhesion.

[0017] To address the waste disposal and heat distribution characteristics within the working space, the panel area features a main drain hole and side drain holes, providing a gravity-guided downward release channel for the peeled scales and preventing the accumulation of biological waste around the operating components. A protective cover on the top of the frame isolates external impurities, and its internal rectangular cavity, together with the maintenance plate, establishes an independent housing area for the power mechanism. Heat dissipation holes distributed on the maintenance plate create a heat dissipation path, directing the heat dissipated by the servo motor to the external environment and inhibiting heat accumulation inside the equipment. A handle on the maintenance plate facilitates daily opening and maintenance of the internal power source. The entire system's mechanical structure is arranged according to material displacement patterns and heat release paths, ensuring smooth operation of the descaling and cleaning process.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] In one embodiment: Refer to Figure 1-7 The fish scale removal equipment has a core structure including a frame 1. A panel 11 is fixedly installed on the top of the frame 1. A main drain hole 31 is opened in the middle of the panel 11. An inclined discharge plate 7 is fixedly installed at one end of the main drain hole 31. Drain side holes 36 are opened on both sides of the top of the panel 11. The inner walls of both sides of the drain side holes 36 are provided with interconnected strip-shaped sliding holes 33. Sliding blocks 34 are slidably connected inside the strip-shaped sliding holes 33. A mounting support plate 29 is fixedly installed on the top of the sliding block 34. A conveying component, a scraping component, and a cleaning component are set on the top of the mounting support plate 29. The conveying component and the cleaning component are located on both sides of the scraping component. An adjustment component for adjusting the gap between the two mounting support plates 29 is provided inside the frame 1. Preferably, the frame 1 is made of stainless steel, the panel 11 is made of wear-resistant steel plate, and the conveyor belt 18 is made of rubber to ensure the durability and stability of the equipment.

[0022] Specifically, the conveying assembly includes two symmetrically arranged drive shafts 24 rotatably connected to the top of the mounting support plate 29. A conveyor roller II 23 is fixedly sleeved on the outer wall of each drive shaft 24. The same conveyor belt I 8 is drivenly sleeved on the outer wall of the two conveyor rollers II 23. Multiple rubber strips 26 are fixedly installed on the outer wall of the conveyor belt I 8. In use, fish are placed between the two conveyor belts I 8 through the clearance hole 6. The servo motor III 25 is started, and its output shaft drives the drive shaft 24 to rotate. The drive shaft 24 then drives the conveyor rollers II 23 to rotate, which in turn drives the outer conveyor belt I 8 forward. The conveyor belt I 8 then drives the inner fish forward. Furthermore, the rubber strips 26 increase friction and can adapt to the size of the fish through slight deformation, ensuring that the fish are not easily displaced during transport and guaranteeing conveying stability.

[0023] Furthermore, the scraping assembly includes two rotating rods rotatably connected to the top of the mounting support plate 29. A scraping shaft 27 is fixedly sleeved on the outer wall of each rotating rod. Multiple scraping protrusions 28 are fixedly installed on the outer wall of the scraping shaft 27. Synchronous pulleys are fixedly sleeved on the outer walls of both rotating rods. The same synchronous belt is driven by the outer walls of the two synchronous pulleys. When the servo motor II 22 is started, its output shaft drives one of the scraping shafts 27 to rotate, and through the external synchronous belt and synchronous pulley, drives the other scraping shaft 27 to rotate. The scraping shaft 27 drives the scraping protrusions 28 on its outer wall to rotate, and the scraping protrusions 28 scrape off the fish scales. The fish scales are scraped off by the two sets of scraping protrusions 28. The fish rolls forward on multiple support rollers 30 below. The gaps between the multiple support rollers 30 are only for the fish scales to pass through, ensuring the fish is transported forward normally. This dual scraping action improves the thoroughness of fish scale removal and reduces residue.

[0024] Furthermore, the cleaning assembly includes two symmetrically arranged rotating shafts II15 rotatably connected to the top of the mounting support plate 29. A conveyor roller I21 is fixedly sleeved on the outer wall of the rotating shaft II15. Multiple conveyor belts II9 are drivenly sleeved on the outer wall of the conveyor roller I21. Multiple rubber blocks 20 are fixedly installed on the outer wall of the conveyor belts II9, with gaps between the multiple conveyor belts II9. Multiple mounting cylinders 17 are rotatably connected to the top of the mounting support plate 29. Multiple brush bristles 18 are fixedly installed on the outer wall of the mounting cylinders 17. A rotating shaft I14 is fixedly installed on the top of the mounting cylinders 17. A driven gear 13 is fixedly sleeved on the outer wall of the rotating shaft I14. A driving gear 16 is fixedly sleeved on the outer wall of one of the rotating shafts II15. The multiple driven gears 13 mesh with each other, and the driving gear 16 meshes with the nearest driven gear 13. After the fish scales are scraped off, a servo motor I19 is started. The output shaft of the servo motor I19 drives the rotating shaft II15. 5. Rotation: Rotating shaft II15 drives conveyor roller I21 to rotate, which in turn drives conveyor belt II9 to transport the fish forward. Conveyor belt II9 can also help transport the fish forward, and finally discharge it outward through inclined discharge plate 7. Simultaneously, rotating shaft II15 can drive drive gear 16 to rotate, which in turn drives multiple driven gears 13 to rotate in sequence. Driven gears 13 drive rotating shaft I14 to rotate, which in turn drives mounting cylinder 17 to rotate. Mounting cylinder 17 drives brush bristles 18 to rotate. Since there are gaps between multiple conveyor belts II9, brush bristles 18 extend from inside the gaps and continuously beat the fish scales in both forward and reverse directions to prevent the fish scales from sticking to the fish after they fall off, thus improving the cleaning effect. At the same time, small water spray nozzles can be set near brush bristles 18. The water spray nozzles are connected to an external water source and spray clean water onto the surface of the fish to assist the brush bristles 18 in cleaning, prevent the fish scales from sticking together, and ensure that the surface of the fish is clean.

[0025] Specifically, the adjustment components include a bidirectional lead screw 32 that rotates through the inside of the frame 1, a rectangular plate 35 fixedly installed at the bottom of the sliding block 34, the bidirectional lead screw 32 threaded through the two rectangular plates 35, a handwheel 10 fixedly installed at one end of the bidirectional lead screw 32, and a dust cover fitted over the outside of the bidirectional lead screw 32. The two ends of the dust cover are fixedly connected to the inner wall of the frame 1 to prevent fish scale debris from entering the thread gap of the lead screw. In use, the handwheel 10 can be rotated as needed, which drives the bidirectional lead screw 32 to rotate. The bidirectional lead screw 32 drives the two rectangular plates 35 to move laterally. The rectangular plates 35 drive the sliding block 34 to slide inside the strip-shaped sliding hole 33. The sliding block 34 drives the upper mounting support plate 29 to move laterally. At this time, the distance between the two mounting support plates 29 changes, thus adapting to fish of different sizes without the need to replace equipment parts, reducing the difficulty of operation and expanding the applicability of the equipment.

[0026] Based on this, a protective cover 2 is fixedly installed on the top of the frame 1. A clearance hole 6 is provided at the bottom of the protective cover 2. A rectangular cavity 12 is provided on one side of the top of the protective cover 2. Multiple horizontal holes are provided at the bottom of the rectangular cavity 12, and these horizontal holes communicate with the clearance hole 6. Multiple mounting plates are slidably connected to the inner wall of the bottom of the rectangular cavity 12. Servo motor I 19, servo motor III 25, and servo motor II 22 are fixedly installed on the top of the multiple mounting plates, respectively. The output shaft of servo motor III 25 is fixedly connected to the top of one of the drive shafts 24. The output shaft of servo motor II 22 is fixedly connected to the top of one of the rotating rods. The output shaft of servo motor I 19 is fixedly connected to the top of one of the rotating shafts II 15. The rectangular cavity 12 is fixedly connected, and a maintenance plate 4 is hinged to the top. A handle 5 is fixedly installed on the top of the maintenance plate 4. Multiple heat dissipation holes 3 are opened inside the maintenance plate 4. The protective cover 2 can protect the internal conveying components, scraping components, and cleaning components, preventing debris from entering and affecting the operation of the equipment. At the same time, the maintenance plate 4 on the protective cover 2 can be opened through the handle 5, which facilitates the maintenance of internal power components such as servo motor I19, servo motor II22, and servo motor III25, ensuring the long-term stable operation of the equipment. The heat dissipation holes 3 on the maintenance plate 4 can dissipate the heat generated during the operation of the servo motor in time, preventing the motor from being damaged due to overheating and extending the service life of the equipment.

[0027] This application can be used in the field of fish scale processing, or in other fields applicable to this application.

[0028] In another embodiment: Reference Figure 1-7 This invention relates to a high-efficiency fish scale removal device and its fish scale cleaning method, which is applied in the field of fish scale processing. The structure of this embodiment is basically the same as that of the aforementioned embodiments, except that: on this basis, the main drain hole 31 and the side drain hole 36 on the panel 11 can discharge the scraped fish scales in a timely manner, avoiding the accumulation of fish scales inside the device and affecting the operation of the device. The inclined discharge plate 7 facilitates the rapid discharge of fish after the fish scales are scraped, further improving the processing efficiency. The overall structure is tightly connected, and the components work together to stably realize the entire process of fish scale removal, meeting the actual needs in the fish processing process.

[0029] It also includes a controller, which is a PLC controller. The controller is electrically connected to servo motor I19, servo motor II22, and servo motor III25 respectively. It is used to control the synchronous start and stop of the three servo motors and can adjust the speed of each servo motor according to the fish scale cleaning requirements to ensure coordinated operation of the conveying component, scraping component, and cleaning component.

[0030] This device requires regular maintenance, specifically including: regularly adding lubricating oil to the bidirectional lead screw 32, rotating rod, rotating shaft I 14, and rotating shaft II 15; regularly cleaning the fish scales and debris adhering to the brush bristles 18; regularly checking the tension of the conveyor belt I 8 and conveyor belt II 9 and adjusting it in time; and regularly replacing the severely worn brush bristles 18, rubber strips 26, and rubber blocks 20.

[0031] However, as is well known to those skilled in the art, the working principles and wiring methods of the controller, servo motor I19, servo motor II22, and servo motor III25 are all conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

According to the size of the fish to be processed, turn the handwheel (10) to drive the double-acting screw (32) to rotate. The double-acting screw (32) drives the two rectangular plates (35) to move in opposite directions, thereby driving the two mounting support plates (29) to move synchronously. After adjusting to the spacing that fits the fish body, stop turning the handwheel (10). S2: Start the equipment and turn on servo motor I (19), servo motor II (22) and servo motor III (25). Servo motor III (25) drives the drive shaft (24) to rotate, which drives the conveyor belt I (8) to run. Servo motor II (22) drives the rotating rod to rotate, which drives the two scraping shafts (27) to rotate synchronously through the synchronous wheel and synchronous belt. Servo motor I (19) drives the rotating shaft II (15) to rotate, which drives the conveyor belt II (9) to run. At the same time, the drive gear (16) drives the driven gear (13) to rotate, which drives multiple mounting cylinders (17) and brush bristles (18) to rotate synchronously. S3: Fish body conveying and scaling. The fish body to be processed is put into the conveyor belt I (8) through the clearance hole (6) at the bottom of the protective cover (2). The rubber strip (26) on the conveyor belt I (8) fits the fish body and drives the fish body to be conveyed towards the scraping component. The scaling protrusion (28) on the scaling shaft (27) rotates synchronously to completely scrape the fish scales on the surface of the fish body. The scraped fish scales are discharged through the main drain hole (31) and the side drain hole (36) on the panel (11). S4: Fish body cleaning. After the fish scales are scraped off, the fish body is transported to the cleaning component by conveyor belt I (8). Conveyor belt II (9) drives the fish body to continue moving. At the same time, the rotating bristles (18) extend from the gap between the conveyor belts II (9) to knock and clean the residual fish scales adhering to the surface of the fish body. S5: Discharge and shutdown. After cleaning, the fish body is discharged through the inclined discharge plate (7) to complete the fish scale cleaning operation. After the operation is completed, all servo motors are turned off. The inspection plate (4) can be opened through the handle (5) to inspect and maintain the equipment and servo motors.
