Description

Technical Field

[0001] This invention belongs to the technical field of automatic processing equipment for aquatic products, and specifically relates to an integrated intelligent equipment for the initial processing of ribbonfish. Background Technology

[0002] Ribbonfish is one of the most commonly consumed sea fish. Its laterally compressed body and scaleless, easily damaged surface necessitate processing, typically involving gutting, cleaning, and cutting. Traditional ribbonfish processing is highly manual, leading to low production efficiency. Current ribbonfish processing equipment often uses straight-bladed knives for gutting, but because ribbonfish flesh is highly elastic, the cut easily retracts and closes, making subsequent cleaning difficult and resulting in high rates of visceral residue – a common industry problem. Furthermore, the slender shape of ribbonfish means existing equipment lacks effective adaptive limiting structures during transport and gutting, resulting in poor clamping stability, easy slippage, and even damage to the fish. This also limits its adaptability to different sizes of ribbonfish. Simultaneously, existing processing equipment lacks intelligent technologies such as the Internet of Things (IoT), making remote monitoring and intelligent control of the processing process difficult, hindering the information-based management and traceability of the entire production process.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1-3As shown, the integrated intelligent equipment for primary processing of ribbonfish provided by this invention includes a frame 1, a feed inlet 2, an inclined filter 7, an adaptive clamping and conveying module, a gutting and eviscerating module, a fixed-length cutting module, a cold chain temporary storage module 8, and a controller. The frame 1 is a rectangular frame structure and is placed on the ground. The feed inlet 2 is installed on the outer side of the top front end of the frame 1. The cold chain temporary storage module 8 is located inside the rear end of the frame 1. The adaptive clamping and conveying module includes a rectangular baffle 4, a compression spring 5, a limiting block 6, support rods 16, and a belt conveyor. A support rod 16 is vertically installed at each of the four corners of the top surface of the frame 1. The rectangular baffle 4 is horizontally positioned above the frame 1, with a notch formed at each of the four corners for penetrating the support rods 16. The device includes a fixed hole with a horizontal strip hole 17 at the front and a row of openings 18 spaced apart at the rear. Each support rod 16 has a compression spring 5 installed on its upper part to press down on the rectangular baffle 4. The belt conveyor includes a synchronous conveyor belt 3, a conveyor shaft, and a drive motor. Two conveyor shafts are rotatably mounted on the front and rear ends of the bottom of the rectangular baffle 4. Multiple synchronous conveyor belts 3 are arranged side-by-side on the two conveyor shafts, with their rear ends positioned above the cold chain temporary storage module 8. The output shaft of the drive motor is connected to one end of any one of the conveyor shafts. Multiple limiting blocks 6 are spaced apart on the outer surface of each synchronous conveyor belt 3, and the limiting blocks 6 on all synchronous conveyor belts 3 are positioned correspondingly. The laparotomy and evisceration module includes a laparotomy knife 9. The machine consists of an internal evisceration tool 10, a first micro stepper motor 11, a second micro stepper motor 12, guide rails 19, a lead screw 20, a lead screw seat 21, and a tool execution bracket 22. Two guide rails 19 are installed parallel to each other on the outer sides of the horizontal holes 17 on the rectangular baffle 4. A lead screw seat 21 is slidably mounted on each guide rail 19. The two ends of the lead screw 20 are respectively mounted on the two lead screw seats 21. The output shaft of the second micro stepper motor 12 is connected to one end of the lead screw 20. The first micro stepper motor 11 is mounted on the top surface of the frame 1, and its output shaft is connected to a lead screw seat 21. The upper part of the tool execution bracket 22 is mounted on the lead screw 20 via a lead screw nut. Both the laparotomy tool 9 and the internal evisceration tool 10 are horizontally positioned and rotate at different speeds. The cutting tool 9 is mounted on the lower two sides of the tool execution bracket 22, and the cutting tool 9 is located inside the tool execution bracket 22. The fixed-length cutting module includes a cutter shaft 23, a high-speed cutting circular blade 13, and a servo motor. The cutter shaft is mounted laterally on the rear of the bottom surface of the rectangular baffle 4. The center holes of multiple high-speed cutting circular blades 13 are spaced apart on the cutter shaft and located in the gap between adjacent synchronous conveyor belts 3 and on the outermost side. At the same time, each high-speed cutting circular blade 13 is located directly below an opening 18 on the rectangular baffle 4. The output shaft of the servo motor is connected to one end of the cutter shaft. The inclined filter 7 is located in the lower inner part of the frame 1, with the high end located below the rear end of the synchronous conveyor belt 3 and the low end located at the bottom front end of the frame 1.The controller is electrically connected to the drive motor, the first micro stepper motor 11, the second micro stepper motor 12, and the servo motor, respectively, and is also wirelessly connected to the control center.

[0019] The integrated intelligent equipment for primary processing of ribbonfish also includes a cleaning module; the cleaning module includes a high-pressure water mist nozzle 14 and a spray nozzle 15; multiple high-pressure water mist nozzles 14 are respectively installed on the top surface of the rectangular baffle 4 near the opening 18; the spray nozzle 15 is installed on the lower part of the tool execution bracket 22 and is inclined towards the tool cutting operation area, and both the high-pressure water mist nozzle 14 and the spray nozzle 15 are connected to the water supply equipment through pipelines.

[0020] The controller uses an STM32 microcontroller.

[0021] The frame 1 is made of profiles welded together.

[0022] The visceration removal knife 10 is saucer-shaped, with a wedge-shaped cutting edge on the outer circumference. The wedge angle is 15°-25°. It is used to scrape off the internal organs after the abdominal cutting knife 9 cuts open the fish belly. This angle can avoid the problem of the fish meat being overcut due to an excessively large wedge angle, or the inability to effectively open the cut due to an excessively small wedge angle.

[0023] The feed inlet 2 is an inclined plate structure, with its lower edge connected to the front end of the frame 1 located below the synchronous conveyor belt 3.

[0024] The inclined filter screen 7 is made of stainless steel.

[0025] The cold chain temporary storage module 8 uses a refrigerated box.

[0026] The working principle of the integrated intelligent equipment for primary processing of ribbonfish provided by this invention is described below:

[0027] When initial processing of ribbonfish is required, the operator first uses the controller to adjust the position of the lead screw seat 21 on the guide rail 19 according to the width of the ribbonfish to be processed via the first micro stepper motor 11, i.e., longitudinal feeding, thereby determining the depth of belly cutting of the ribbonfish; under the control of the controller, the drive motor and cleaning module are started, and the drive motor drives the synchronous conveyor belt 3 from... Figure 1The feeder rotates counterclockwise from the perspective of the feeder, then places the ribbonfish flat inside the feed inlet 2 with its belly facing forward. The limiting block 6 then guides the ribbonfish onto the synchronous conveyor belt 3 until it moves below the horizontal hole 17 on the rectangular baffle 4. At this point, the drive motor stops, and the ribbonfish's back is precisely pressed between the synchronous conveyor belt 3 and the bottom surface of the rectangular baffle 4. Simultaneously, the rear end of the back is blocked by the limiting block 6. This prevents the ribbonfish from slipping during the subsequent gutting and evisceration process, thus ensuring operational accuracy. The second micro stepper motor 12 is then activated, driving the cutter via the lead screw 20. The support 22 and its components move laterally towards the ribbonfish, i.e., feed laterally. Then, the rotating evisceration blade 9 first contacts the fish's belly and performs the evisceration. As the blade continues to move along the support 22, the rotating evisceration blade 10 then probes into the already cut belly, using its wedge-shaped edge to open the incision and simultaneously scraping away the visceral tissue from the abdominal cavity. At the same time, clean water sprayed from the nozzle 15 provides high-pressure rinsing to the surface and abdominal cavity of the ribbonfish, preventing blood and visceral residue from adhering to the fish or work area, assisting the evisceration blade 10 in completing the visceral removal and further reducing the visceral residue rate. Subsequently, the visceral tissue and blood will fall onto the inclined filter 7 below, where they are guided and collected. Afterward, the blade moves the support 22 in the reverse direction to reset, stopping the operation of the second micro stepper motor 12. Thus, the evisceration, visceral cutting and scraping, and high-pressure rinsing of the ribbonfish are completed simultaneously in one stroke. Then, the drive motor is restarted to run the synchronous conveyor belt 3. When the ribbonfish, after being gutted and removed, moves to below a row of openings 18 on the rectangular baffle 4, the drive motor stops. The servo motor is then activated, driving multiple high-speed cutting blades 13 to rotate at high speed, thus cutting the ribbonfish into multiple segments, as well as head and tail segments. The fish segments, as finished products, are supported by the synchronous conveyor belt 3 and eventually fall into the cold chain temporary storage module 8. The head and tail segments, not supported by the synchronous conveyor belt 3, fall naturally onto the inclined filter 7 or into a separately set waste collection box, achieving automatic separation of the head and tail from the finished product, eliminating the need for manual secondary sorting. During the above production process, the controller can wirelessly upload the above process parameters to the control center for precise control of the production process.
