Description

Technical Field

[0001] This invention relates to the field of fish pretreatment and processing, and particularly to a pretreatment device for processing scaled fish. Background Technology

[0002] Fish is popular among the general public due to its delicious taste and health benefits, resulting in high sales volume. Processing fish involves scaling, gutting, and removing the internal organs before it can be eaten. Currently, most of these steps are done manually.

[0003] Therefore, Chinese invention patent CN108669206B discloses a vertical integrated fish scale and belly cleaning machine, including a frame. The inner side of the frame, from top to bottom, is equipped with a fish inlet funnel, a side fish scale scraping mechanism, a fish belly and back scale scraping and belly opening mechanism, and a toothed chain conveyor mechanism. A power mechanism is provided on the side of the frame. The fish inlet funnel of this invention can automatically adjust its opening and closing width according to the size of the fish, ensuring that fish of different sizes do not tilt during descent. The side fish scale scraping mechanism and the fish belly and back scale scraping and belly opening mechanism can quickly scrape off the scales on the sides and belly of the fish, while simultaneously opening the belly. The toothed chain conveyor mechanism can transport the fish out of the device after processing. The power mechanism provides power to each mechanism, ensuring its normal operation.

[0004] This equipment is designed to process fish scales, but the internal organs need to be removed later. However, the inner wall of the fish's abdomen contains a black membrane. During the pre-processing of the fish, the treatment of this black membrane is neglected. Existing equipment exists to treat this membrane separately, but because it adheres closely to the inner wall, the existing cleaning device vibrates and separates from the fish upon contact, failing to thoroughly remove the membrane. Furthermore, the existing cleaning device cannot be adjusted in time for fish of different sizes, potentially damaging the fish's interior. If operators need to adjust the device for different sized fish each time, the efficiency of fish processing will inevitably decrease.

[0005] Therefore, it is necessary to provide a pretreatment device for processing scaled fish to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a pre-treatment device for processing scaled fish, to solve the problem in the background art where, after processing fish scales, it is necessary to remove the internal organs from the fish's abdomen. However, the inner wall of the fish's abdomen contains a black mucus membrane. During the pre-treatment of fish, the treatment of this black membrane is often neglected. Existing devices have separate equipment for treating the black membrane, but because the black membrane is attached to the inner wall of the fish, the existing cleaning device separates from the fish due to vibration when it comes into contact with the inner wall, making it impossible to thoroughly clean the black membrane. Furthermore, existing cleaning devices cannot be adjusted in time for fish of different sizes, which may cause damage to the inside of the fish. If operators need to adjust the device for different sizes of fish each time, it will inevitably reduce the efficiency of fish processing.

[0007] Based on the above ideas, the present invention provides the following technical solution: a pretreatment device for processing scaled fish, including a processing frame, a filter plate fixedly connected inside the processing frame, a collection box at the bottom of the processing frame, a through groove at the top of the processing frame, a limiting member for fish entry at the upper part of the through groove, a first descaling mechanism for removing scales from the belly of the fish inside the processing frame, and a second descaling mechanism for removing scales from both sides of the fish at the lower part of the first descaling mechanism.

[0013] As a further aspect of the present invention: each of the two expansion plates is provided with a limiting clamp on the side away from each other, and a plurality of fixing rods are fixedly connected to one side of the expansion plate. The plurality of fixing rods pass through the limiting clamp and are slidably connected to the limiting clamp. A sixth spring is fixedly connected between the fixing rod and the limiting clamp. The side of the limiting clamp near the expansion plate is set in a sawtooth shape.

[0014] As a further aspect of the present invention: the laparotomy assembly includes a cutting disc disposed inside the connecting frame, the cutting disc passing through the connecting frame and rotatably connected to the connecting frame, and a third motor fixedly connected to the outside of the connecting frame, the output end of the third motor being fixedly connected to the cutting disc.

[0015] As a further aspect of the present invention: the limiting member includes two symmetrically arranged arc-shaped feeding grooves, and a deflection plate is fixedly connected to the outer side of each of the two arc-shaped feeding grooves. The deflection plate is hinged to the processing frame, and a first spring is fixedly connected between the deflection plate and the processing frame.

[0016] As a further aspect of the present invention: the first dephosphorization mechanism includes two first limiting plates, each of the two first limiting plates having two first sliding blocks slidably connected inside, a second spring being fixedly connected between the first sliding block and one end inside the first limiting plate, a rotating rod being rotatably connected between the two opposing second springs, a dephosphorization wheel being fixedly connected to the outside of the rotating rod, and a servo motor being fixedly connected to the outside of the two first sliding blocks on the same side, the output end of the servo motor being fixedly connected to the rotating rod.

[0017] As a further aspect of the present invention: the second dephosphorization mechanism includes two dephosphorization rollers, each of which is rotatably connected to a second sliding block at both ends. A second limiting plate is slidably connected to the outer side of each second sliding block. The second limiting plate is fixedly connected to the processing frame. A third spring is fixedly connected between the second sliding block and the second limiting plate. A first gear is fixedly connected to both ends of one of the dephosphorization rollers.

The seventh spring and the first telescopic rod are both fixedly connected to the top of the inside of the processing frame. A second motor is fixedly connected to the outer side of one of the second sliding blocks. The output end of the second motor is fixedly connected to the dephosphorization roller.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The fish is scaled using a grid-like arrangement of two descaling rollers and two descaling wheels. The second motor drives the descaling rollers, which in turn rotate via a belt drive between the driven wheel and the two first pulleys. The belt remains taut due to the seventh spring and the first telescopic rod between the L-shaped fixed plate on the driven wheel and the processing frame. When the first pulley drives the second gear, the second gear drives the meshing first gear, which in turn drives the other descaling roller. This causes the two descaling rollers to rotate in opposite directions, pushing the fish downwards and peeling off the scales on the outside of the fish, allowing the descaling rollers to adhere to the fish's surface for descaling.

[0020] 2. The rotating disc scrapes the fish's internal organs from the belly. Meanwhile, for the black membrane on the fish's inner wall, a cleaning component is installed on one side of the expansion plate. A transmission component drives a third pulley, which in turn drives a second pulley via a belt. The second pulley drives a connecting shaft, which in turn drives a rotating support rod via two meshing bevel gears. The rotating support rod, through a limiting block inside the cleaning roller, drives the cleaning roller to rotate. At this point, the fish is in contact with the expansion plate, and the cleaning roller extends beyond the expansion plate, thus contacting the black membrane on the fish's inner wall. The rotation of the cleaning roller removes the black membrane from the fish's inner wall. During the removal of the fish's internal organs, the black membrane inside the fish is removed simultaneously.

[0021] 3. The cleaning roller is inserted into the fish. Under the action of the fifth spring, the cleaning roller can be pushed to fully penetrate into the fish's abdomen and remove the black membrane on the inner wall of the fish. The cleaning roller can be extended or retracted according to the size of the fish, so that the membrane removal process can be carried out for fish of different sizes, avoiding the need for constant adjustment and speeding up the pre-processing efficiency of the fish.

Detailed Implementation

[0033] like Figures 1 to 9 As shown, a pretreatment apparatus for processing scaled fish includes the following embodiments:

[0034] Example 1

[0035] like Figures 1 to 9 As shown, a pretreatment device for processing scaled fish includes a processing frame 1, a filter plate 11 fixedly connected inside the processing frame 1, a collection box 12 provided at the bottom of the processing frame 1, a through groove opened at the top of the processing frame 1, a limiting member for fish entry provided at the upper part of the through groove, the limiting member includes two symmetrically arranged arc-shaped feeding grooves 2, a deflection plate 201 fixedly connected to the outer side of each of the two arc-shaped feeding grooves 2, the deflection plate 201 is hinged to the processing frame 1, and a first spring 202 is fixedly connected between the deflection plate 201 and the processing frame 1.

[0036] The processing frame 1 contains a first descaling mechanism 3 for descaling the fish belly, and a second descaling mechanism 4 for descaling the fish sides is located below the first descaling mechanism 3. In practice, the fish is placed inside the processing frame 1 through a limiting member. First, the first descaling mechanism 3 removes the scales from the fish belly, and then the fixing frame 5 removes the scales from the fish sides. However, in actual operation, due to the different sizes of the fish, the descaling mechanism often fails to adhere to the fish surface. Therefore, in this solution, the following method is adopted:

[0037] Please refer to Figure 1-3The first dephosphorization mechanism 3 includes two first limiting plates 301. Two first sliding blocks 302 are slidably connected inside each of the two first limiting plates 301. A second spring 303 is fixedly connected between the first sliding block 302 and one end inside the first limiting plate 301. A rotating rod 304 is rotatably connected between the two opposing second springs 303. A dephosphorization wheel 305 is fixedly connected to the outside of the rotating rod 304. A servo motor is fixedly connected to the outside of each of the two first sliding blocks 302 on the same side. The output end of the servo motor is fixedly connected to the rotating rod 304.

[0038] In practical use, when the fish is fed into the space between the two descaling wheels 305 through the arc-shaped feeding trough 2, the width of the fish will push the two descaling wheels 305 apart. Since the first sliding block 302 at both ends of the rotating rod 304 is fixed to the first limiting plate 301 by the second spring 303, the two descaling wheels 305 can fit tightly against the belly and back of the fish. By starting the first motor, the rotating rod 304 is driven to rotate. At the same time, the two rotating rods 304 drive the descaling wheels 305 to rotate, thereby removing the scales on the back and belly of the fish. The clockwise rotation causes the fish to be rolled into the lower second descaling mechanism 4 for processing.

[0039] Please refer to Figure 3-4 The second dephosphorization mechanism 4 includes two dephosphorization rollers 401. Each end of the two dephosphorization rollers 401 is rotatably connected to a second sliding block 403. A second limiting plate 402 is slidably connected to the outer side of each second sliding block 403. The second limiting plate 402 is fixedly connected to the processing frame 1. A third spring 404 is fixedly connected between the second sliding block 403 and the second limiting plate 402. Each end of one dephosphorization roller 401 is fixedly connected to a first gear 405. A second gear 406 is meshed with the outer side of the first gear 405. The second gear 406 and one end of the other dephosphorization roller 401 are... A first pulley 407 is fixedly connected, and a driven wheel 411 is provided above the second limiting plate 402. The driven wheel 411 and the two first pulleys 407 are connected by belt drive. An L-shaped fixed plate 408 is rotatably connected to one side of the driven wheel 411. A seventh spring 410 and a first telescopic rod 409 are fixedly connected to the top of the L-shaped fixed plate 408. The seventh spring 410 and the first telescopic rod 409 are both fixedly connected to the top of the inside of the processing frame 1. A second motor is fixedly connected to the outside of one of the second sliding blocks 403. The output end of the second motor is fixedly connected to the dephosphorization roller 401.

[0040] In practical use, when the two descaling rollers 401 are pressed against the sides of the fish, the second sliding blocks 403 at both ends of the descaling rollers 401 are fixed to the second limiting plate 402 by the third spring 404, thereby making the descaling rollers 401 fit against the sides of the fish. The descaling rollers 401 and the descaling wheels 305 are both set with teeth on their outer sides. When rotating, the scales can be peeled off the fish. The two descaling wheels 305 and the two descaling rollers 401 are arranged in a grid pattern to maintain stability when descaling the fish. By starting the second motor, the second motor drives the descaling rollers 401 to rotate. The descaling rollers 401 are connected between the driven wheel 411 and the two first pulleys 407. The belt drive causes another first pulley 407 to rotate. Due to the seventh spring 410 and the first telescopic rod 409 between the L-shaped fixed plate 408 on the driven pulley 411 and the processing frame 1, the belt is always kept taut. When the first pulley 407 drives the second gear 406 to rotate, the second gear 406 drives the meshing first gear 405 to rotate, and then the first gear 405 drives the other descaling roller 401 to rotate. Thus, the two descaling rollers 401 rotate in opposite directions, pushing the fish down and peeling off the scales on the outside of the fish, so that the descaling roller 401 can adhere to the surface of the fish to remove scales.

[0041] In summary, by using two descaling rollers 305 and two descaling wheels 401 to descale fish of different sizes, and by limiting the fish's movement in all directions, an automatic descaling process is achieved for fish of different sizes.

[0042] Example 2

[0043] Please refer to Figure 5-9 The difference between this embodiment and Embodiment 1 lies in the fact that, during the pretreatment of the fish, the treatment of the black membrane on the inner wall of the fish is neglected. Existing methods for cleaning the black membrane on the inner wall of the fish are not thorough enough. Since the black membrane is attached to the inner wall of the fish, existing cleaning devices may separate from the fish due to vibration when in contact with the inner wall, making it impossible to thoroughly clean the black membrane. Furthermore, the cleaning device cannot be adjusted in time for fish of different sizes, which may damage the fish. Therefore, in this embodiment, the second descaling mechanism 4 is provided with a fixed frame 5 fixedly connected to the treatment frame 1 at its lower part. A connecting frame 6 is provided inside the fixed frame 5. A ventriloquizing component is provided inside the connecting frame 6. The ventriloquizing component includes a cutting blade 601 disposed inside the connecting frame 6. The cutting blade 601 passes through the connecting frame 6 and is rotatably connected to the connecting frame 6. A third motor 602 is fixedly connected to the outside of the connecting frame 6. The output end of the third motor 602 is fixedly connected to the cutting blade 601.

[0044] Both sides of the connecting frame 6 are fixedly connected to the expansion plate 7. A transmission rod 701 is provided between the two transmission rods 701. A rotating disk 702 is fixedly connected to the outside of the transmission rod 701. There is a cleaning component 703 on the opposite side of the two expansion plates 7. A transmission component is provided between the transmission rod 701 and the cleaning component 703. When the gutting component guts the fish, the two sides of the fish belly descend along the expansion plate 7. The internal organs of the fish are removed by the rotating disk 702, and the cleaning component 703 is driven by the transmission component to remove the black membrane on the side wall of the fish belly.

[0045] The transmission rod 701 is rotatably connected to one of the support plates 7, and a fourth motor 704 is fixedly connected to one side of the other support plate 7. The output end of the fourth motor 704 is fixedly connected to the transmission rod 701.

[0046] The cleaning component 703 includes a rotating support rod 7031 that passes through and is rotatably connected to the support plate 7. A cleaning roller 7032 is sleeved on the outside of the rotating support rod 7031. A sliding groove is opened on the outside of the rotating support rod 7031. A limiting block is fixed inside the cleaning roller 7032. The limiting block extends into the sliding groove and slides with the rotating support rod 7031. A fifth spring 7033 is fixedly connected between one end of the rotating support rod 7031 and one end inside the cleaning roller 7032.

[0047] The transmission component includes a connecting shaft 802 that is rotatably connected to the support plate 7. Both the connecting shaft 802 and the rotating support rod 7031 are fixedly connected to a bevel gear 801 at their respective ends. The two bevel gears 801 mesh with each other. A second pulley 803 is fixedly connected to the outside of the connecting shaft 802. A third pulley 804 is fixedly connected to the outside of the transmission rod 701. The third pulley 804 and the second pulley 803 are connected by a belt drive.

[0048] A connecting seat 10 is fixedly connected to the top of the connecting frame 6. A contact wheel 102 is rotatably connected inside the connecting seat 10. A pressure sensor 103 is fixedly connected to the side of the connecting seat 10 near the contact wheel 102. A hydraulic telescopic rod 101 is fixedly connected between the connecting frame 6 and the fixed frame 5. Two guide plates 501 are provided inside the fixed frame 5. The two guide plates 501 are respectively provided on both sides of the connecting frame 6. Multiple second telescopic rods 502 and a fourth spring 503 are fixedly connected between the guide plates 501 and one side of the inner wall of the fixed frame 5. The fourth spring 503 is sleeved on the outside of the second telescopic rods 502.

[0049] In practical use, when the fish moves under the push of the two descaling rollers 401 during the descaling process, it falls smoothly into the guide plates 501 inside the fixed frame 5. The fourth spring 503 between the two guide plates 501 and the fixed frame 5 keeps the fish descending vertically. At this time, the hydraulic telescopic rod 101 is activated, pushing the connecting frame 6. The connecting frame 6 then moves the connecting seat 10, causing the contact wheel 102 to contact the fish. The pressure sensor 103 on the connecting seat 10 (the pressure sensor can be model 103PT124G-1) then... 21T) When the fish is touched, the sensor is activated, so that the hydraulic telescopic rod 101 remains stationary. In order to ensure that the fish can slide down smoothly, the sensing value of the pressure sensor 103 is always kept at a fixed value. By controlling the contraction of the hydraulic telescopic rod 101, the fish can slide down, and then the cutting disc 601 inside the connecting frame 6 is adjusted to cut open the fish's abdomen. At this time, since there are support plates 7 on both sides of the connecting frame 6, when the cut fish slides down under the force of gravity, the two sides of the fish are thrown up and rest on the two support plates 7 respectively, and it descends along the support plates 7, opening up the fish and processing its internal organs.

[0050] Then, by activating the fourth motor 704 between the two expansion plates 7, the fourth motor 704 drives the cleaning component 703 to rotate, which in turn drives the rotating disk 702 to rotate clockwise. The rotating disk 702 then scrapes the fish's internal organs out of its belly. At this point, regarding the black membrane on the fish's inner wall, by setting the cleaning component 703 on one side of the expansion plate 7, the transmission component drives the third pulley 804, which in turn drives the second pulley 803 to rotate via a belt. The second pulley 803 then drives the connecting shaft 802 to rotate. The connecting shaft 802 drives the rotating support rod 7031 to rotate through two meshing bevel gears 801. The rotating support rod 7031 drives the cleaning roller 7032 to rotate through the limiting block inside the cleaning roller 7032. At this time, the fish is in contact with the spreading plate 7, and part of the cleaning roller 7032 extends out of the spreading plate 7. Then the cleaning roller 7032 comes into contact with the black membrane on the inner wall of the fish. The black membrane on the inner wall of the fish is removed by the rotation of the cleaning roller 7032. During the process of removing the fish's internal organs, the black membrane inside the fish is removed simultaneously.

[0051] Furthermore, a fifth spring 7033 is fixedly connected between the cleaning roller 7032 and the rotating support rod 7031. When the cleaning roller 7032 is inserted into the fish, it can be pushed by the fifth spring 7033, allowing it to fully penetrate the fish's abdomen. The rotating support rod 7031 drives the cleaning roller 7032 to rotate through the cooperation of the sliding groove and the limiting block, removing the black membrane from the fish's inner wall. The cleaning roller 7032 can be extended or retracted according to the size of the fish, thus enabling membrane removal for fish of different sizes. This avoids the need for constant adjustments and speeds up the pre-processing efficiency of the fish.

[0052] Further: Each of the two expansion plates 7 is provided with a limiting clamp 902 on the side away from each other. Multiple fixing rods 901 are fixedly connected to one side of the expansion plate 7. The multiple fixing rods 901 pass through the limiting clamp 902 and are slidably connected to the limiting clamp 902. A sixth spring 903 is fixedly connected between the fixing rods 901 and the limiting clamp 902. The side of the limiting clamp 902 near the expansion plate 7 is set in a sawtooth shape.

[0053] In practical use, in order to ensure the stability of the fish during the removal of the black membrane, a limiting clamp 902 is set on one side of the spreading plate 7. After the fish is cut open, it is squeezed between the limiting clamp 902 and the spreading plate 7. Through the sixth spring 903 on the outside of the fixing rod 901, the limiting clamp 902 pushes the fish to contact the spreading plate 7, ensuring that the cleaning roller 7032 maintains stability in the treatment of the black membrane on the inner wall of the fish, and preventing the fish from shaking during the removal of the membrane, which would affect the removal effect. In addition, one side of the limiting clamp 902 is set with a serrated shape, which can be used to remove the scale from the fish body again.

[0054] In this application, a nozzle can be added and water pumped to supply water to the nozzle so that the nozzle can spray water to clean the fish during processing, thereby improving the pretreatment effect. In addition, a filter plate 11 is set up to filter the fish and other internal organs and scales being processed.
