Description

Technical Field

[0001] This invention relates to the field of fish segmentation technology, specifically to an automatic segmentation device based on a seafood processing production line. Background Technology

[0002] Automated segmentation equipment in fish processing production lines typically refers to specialized mechanical devices used in the fish processing flow to automatically segment fish fillets or chunks. This type of equipment can be integrated with preceding processing steps to achieve fixed-size and fixed-shape segmentation of fish meat, effectively improving processing efficiency and ensuring product consistency. It is an important component of modern seafood processing production lines.

[0003] The patent with publication number CN118985679A discloses "a kind of aquatic product processing equipment". The patent describes a technical solution in which "a liquid nitrogen quick-freezing machine quickly freezes aquatic products by using the low temperature generated by liquid nitrogen, and a second conveyor chain then conveys the frozen aquatic products to a cutting device for cutting into small pieces for packaging and transportation".

[0004] The patent with publication number CN119014453A discloses "a fish fillet segmentation and sorting device for aquatic product processing production line". The patent describes a technical solution that "can arrange and store the segmented fish fillets inside a tray, thereby improving the sorting quality".

[0005] However, the existing segmentation equipment has the following defects: there is a lack of effective guiding and positioning devices between the production line and the segmentation equipment. The fish fillets are in a chaotic posture during the conveying process, often exhibiting irregular states such as horizontal or tilted positions. This makes it easy for the segmentation equipment to deviate during segmentation, and even result in missed cuts or incorrect cuts, affecting processing accuracy and production continuity. Summary of the Invention

[0006] An automatic segmentation device based on a seafood processing production line includes a conveying device, which includes a body and a conveyor belt. The conveying device is used to convey fish pieces. A liquid nitrogen tunnel freezer and segmentation equipment are installed on the body of the conveying device. The conveying device is provided with guiding components and multiple holding components. The multiple guiding components are arranged in a linear array on the conveying device. The guiding component is used to adjust and guide the conveying and segmenting posture of the fish pieces, while the maintaining component is used to control the conveying and segmenting rhythm of the fish pieces. The guiding component includes four guide plates arranged in a linear array on the conveying device. The guide plates are located between the liquid nitrogen tunnel freezer and the dividing equipment. Each of the four guide plates is provided with a guide frame. Each of the four guide plates is rotatably connected to a guide plate at the end of the four guide plates closest to the liquid nitrogen tunnel freezer. The retaining component includes a slide bar mounted on the conveying device, three channels formed by four guide plates, two rotating rods in each of the three channels, a bearing block rotatably connected to the top of the rotating rod, the bearing block being fixedly connected to the top surface of the guide plate, and a rubber belt being fixedly connected between the two rotating rods in the same channel.

[0007] Furthermore, the guiding component also includes four horizontal connecting plates fixedly connected to the top surfaces of the four guide plates. Each of the four horizontal connecting plates has a rotating shaft I fixedly connected to its top surface. The four rotating shafts I are slidably connected to the four guide frames. A square rod is slidably connected to the four horizontal connecting plates. A protective shell is fixedly connected to the square rod. A support frame I is fixedly connected to both sides of the outer wall of the protective shell. The support frame I is fixedly connected to the body of the conveying device. A support plate is fixedly connected to the four guide frames. A support frame II is fixedly connected to the square rod. An electric push rod is installed on the support frame II. The telescopic shaft end of the electric push rod is fixedly connected to the support plate. A rotating shaft II is fixedly connected to the top surface of each of the four guide plates. Two rotating shafts II located on the same side are grouped together. A connecting rod is rotatably connected between the two rotating shafts II in the same group. A guide slider is rotatably connected to the end of each of the two guide plates located at the edge of the conveying device body away from the guide plate. Two limiting blocks are symmetrically fixedly connected to the body of the conveying device. A guide groove is opened on the top surface of each of the two limiting blocks.

[0008] Furthermore, the two support frames are symmetrically distributed with the conveyor belt of the conveyor device as the axis, the square rod spans the conveyor belt of the conveyor device, the guide frame is set at an angle, and the four guide frames are arranged symmetrically to the left and right with the conveying direction axis of the conveyor belt of the conveyor device as the reference.

[0009] Furthermore, the two guide sliders are slidably connected to the adjacent guide grooves, and the square rod and the electric push rod are vertically distributed.

[0010] Furthermore, both the guide plate and the outer surface of the guide plate are covered with a rubber layer, and there are gaps between the bottom surface of the guide plate and the conveyor belt of the conveying device.

[0011] Furthermore, the retaining component also includes two symmetrically fixed support frames three fixedly connected to the conveying device body. The slide rod is rotatably connected to both support frames three. One of the support frames three is fixedly connected to a support frame four. A servo motor is fixedly connected to the slide rod, and the output shaft end of the servo motor is fixedly connected to the slide rod.

[0012] Furthermore, the slider is designed to have round ends and a rectangular center.

[0013] Furthermore, the bearing block and the rotating rod are in a limited rotation manner. The rotating rod can rotate circumferentially within the bearing block, but it cannot detach from the interior of the bearing block.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By guiding the operation of the components, the fish piece conveying posture can be forcibly and precisely corrected, which greatly improves the cutting and processing accuracy. There is no need to rework the fish pieces due to cutting deviations or miscuts, which reduces the energy consumption of repeated operation of the cutting equipment and achieves the goal of energy saving in fish piece cutting. Furthermore, it can be adapted to the cutting and processing of fish pieces of different sizes and specifications, improving its versatility and adaptability.

[0015] By using surface micro-freezing instead of complete freezing in existing technologies, the energy consumption of liquid nitrogen tunnel freezers is significantly reduced while meeting the requirements for fish piece segmentation and shaping, thus achieving energy saving and consumption reduction. The surface of the micro-frozen fish pieces is dry and rigidly shaped, eliminating surface stickiness and preventing sticking and jamming during the fish piece transportation and segmentation process. At the same time, it can ensure that the cut is flat and smooth during segmentation, greatly improving the quality of the segmented fish pieces.

[0016] By operating the components, the fish block segmentation and conveying channel is divided into multiple independent waiting areas, and the opening and closing can be controlled individually. This regulates the arrangement of fish blocks, allowing them to enter the segmentation equipment in an orderly manner, ensuring stable fish block segmentation operations, flexibly adjusting the fish block conveying and segmentation rhythm to adapt to different production needs, and greatly improving the equipment's processing flexibility.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Reference Figures 1 to 11 As shown, an automatic segmentation device based on a seafood processing production line includes a conveying device 11 for conveying fish pieces 12.

[0021] The conveying device 11 includes a body and a conveyor belt. The conveying device 11 is a known technology and will not be described in detail here.

[0022] The conveying device 11 is equipped with a liquid nitrogen tunnel freezer 13 and a cutting device 14.

[0023] Among them, the conveyor belt of the conveying device 11 passes through the bottom of the liquid nitrogen tunnel freezer 13 and the dividing device 14.

[0024] Among them, the liquid nitrogen tunnel freezer 13 and the segmentation device 14 are existing known technologies. The liquid nitrogen tunnel freezer 13 has the following technical characteristics: it is a long tunnel-shaped structure, uses liquid nitrogen as a cold source, and continuously introduces liquid nitrogen into the equipment. The liquid nitrogen will rapidly evaporate and absorb heat inside the tunnel, keeping the entire cavity in an extremely low temperature environment. The conveying device 11 carries the fish pieces 12 and smoothly enters from one end of the tunnel and exits from the other end. During the process of passing through the tunnel, the fish pieces 12 are continuously in a strong low-temperature atmosphere, and their own heat will be rapidly absorbed. The water inside the fish pieces 12 will then freeze rapidly, thereby completing the quick-freezing process of the fish pieces 12.

[0025] It should be noted that the application of the liquid nitrogen tunnel freezer 13 differs from existing technologies. Here, only the surface of the fish pieces 12 needs to be slightly frozen as they pass through the liquid nitrogen tunnel freezer 13. After quick-freezing, the surface of the fish pieces 12 becomes rigidly shaped and dry. Unlike existing technologies, it is not necessary to completely freeze the fish pieces 12, resulting in lower energy consumption for the liquid nitrogen tunnel freezer 13 and achieving energy savings.

[0026] Wherein: the liquid nitrogen tunnel freezer 13 is located at the front of the conveying path of the fish pieces 12, and the segmentation device 14 is located at the rear of the conveying path of the fish pieces 12. Specifically: driven by the conveying device 11, the fish pieces 12 first enter the liquid nitrogen tunnel freezer 13 for surface micro-freezing, and then enter the segmentation device 14 to be segmented.

[0027] The conveying device 11 is provided with a guide component and a plurality of retaining components, and the plurality of guide components are arranged in a linear array on the conveying device 11.

[0028] The guiding component includes four guide plates 21 arranged in a linear array on the conveying device 11. The guide plates 21 are located between the liquid nitrogen tunnel freezer 13 and the dividing device 14. A horizontal connecting plate 22 is fixedly connected to the top surface of each of the four guide plates 21. A rotating shaft 23 is fixedly connected to the top surface of each of the four horizontal connecting plates 22. A square rod 24 is slidably connected to the four horizontal connecting plates 22. A protective shell 25 is fixedly connected to both ends of the square rod 24. A support frame 26 is fixedly connected to both sides of the outer wall of the protective shell 25. The support frame 26 is fixedly connected to the body of the conveying device 11. A guide frame 27 is slidably connected to each of the four rotating shafts 23. A support plate 28 is fixedly connected to the four guide frames 27. A support frame is fixedly connected to the square rod 24. 29. An electric push rod 210 is installed on the support frame 29. The telescopic shaft end of the electric push rod 210 is fixedly connected to the support plate 28. A guide plate 211 is rotatably connected to one end of each of the four guide plates 21 near the liquid nitrogen tunnel quick-freezing machine 13. A rotating shaft 212 is fixedly connected to the top surface of each of the four guide plates 211. Two rotating shafts 212 on the same side of the four rotating shafts 212 form a group. A connecting rod 213 is rotatably connected between the two rotating shafts 212 in the same group. A guide slider 214 is rotatably connected to the end of each of the two guide plates 211 located at the edge of the conveying device 11 away from the guide plate 21. Two limiting blocks 215 are symmetrically fixedly connected to the body of the conveying device 11. A guide groove 216 is opened on the top surface of each of the two limiting blocks 215.

[0029] Among them: the two support frames 26 are symmetrically distributed with the conveyor belt of the conveyor device 11 as the axis, and the square rod 24 spans the conveyor belt of the conveyor device 11.

[0030] Among them, the guide frame 27 is set at an angle, and the four guide frames 27 are arranged symmetrically on the left and right with the conveying direction axis of the conveyor belt of the conveyor device 11 as the reference.

[0031] The protective shell 25 encloses the support plate 28, the cross plate 22, the first pivot 23, the guide frame 27, the second support frame 29, the electric push rod 210, the square rod 24, and other structures, with the purpose of providing shielding and protection.

[0032] Wherein: the two guide sliders 214 are slidably connected to the adjacent guide grooves 216 respectively.

[0033] Among them, the square rod 24 and the electric push rod 210 are vertically distributed.

[0034] The outer surfaces of guide plate 21 and guide plate 211 are covered with a rubber layer. There is a gap between the bottom surface of guide plate 21 and guide plate 211 and the conveyor belt of conveying device 11. It should be noted that the function of the gap is to prevent the conveyor belt of conveying device 11 from rubbing against guide plate 21 and guide plate 211, but the gap is not large enough for the fish piece 12 to pass through.

[0035] How the guiding component operates: Before the fish pieces 12 are cut, the lateral spacing of the four guide plates 21 on the conveying device 11 needs to be adjusted so that the width of the three channels formed by the four guide plates 21 corresponds to the width of the fish pieces 12 to be cut in the current batch, as follows: At this time, the user drives the electric push rod 210 to operate, causing the telescopic shaft of the electric push rod 210 to extend and retract. The support plate 28 is moved by the telescopic shaft of the electric push rod 210, and the four guide frames 27 are moved synchronously. During the movement of the guide frames 27, the inner wall of the guide frames 27 generates a thrust on the rotating shaft 23. However, the movement of the rotating shaft 23 is subject to dual constraints: the rotating shaft 23 slides within the guide frame 27, and the rotating shaft 23 moves along the axial direction of the square rod 24 with the horizontal connecting plate 22. Under these dual constraints, the translational motion of the support plate 28 is decomposed by the guide frame 27: one part is the sliding of the rotating shaft 23 within the guide frame 27, and the other part is the movement of the guide plate 21 along the axial direction of the square rod 24 driven by the rotating shaft 23 through the horizontal connecting plate 22.

[0036] Furthermore, since the four guide frames 27 are arranged symmetrically with reference to the conveying direction axis of the conveyor belt of the conveyor device 11, and the tilt angles of the four guide frames 27 are consistent, the movement of the four guide frames 27 drives the corresponding guide plates 21 to move along the square rod 24 at the same distance and speed. That is, as the four guide frames 27 move, the four guide plates 21 can move at equal intervals, and the width of the three channels formed by the four guide plates 21 can change at equal intervals. At this time, the user adjusts the width of the three channels to correspond to the width of the fish pieces 12 to be divided in the current batch.

[0037] During the adjustment of the spacing of the four guide plates 21, the distance between the guide plates 21 and the limiting blocks 215 will change accordingly. Since the guide plates 21 on both sides are connected to the limiting blocks 215 through guide plates 211, the position and angle of the guide plates 211 between the guide plates 21 and the limiting blocks 215 will change accordingly. That is, the guide plates 211 will rotate on the guide plates 21 and the guide sliders 214, and the guide sliders 214 will slide in the guide grooves 216 to cooperate with the change of the position and angle of the guide plates 211, ensuring that the guide plates 211 are always connected between the limiting blocks 215 and the guide plates 21 on the side. As the angle of the guide plates 211 on the side changes, the guide plates 211 on the side will drive the other guide plate 211 on the same side to rotate synchronously and in the same direction through the connecting rod 213.

[0038] Since the four guide plates 211 are located on one side of the three channels formed by the four guide plates 21 near the liquid nitrogen tunnel freezer 13, the four guide plates 211 form an outward extension of the three channels facing the liquid nitrogen tunnel freezer 13, that is, the three channels form a funnel shape facing the liquid nitrogen tunnel freezer 13. This design is used to guide the fish pieces 12 that have been slightly frozen by the liquid nitrogen tunnel freezer 13 into the channels. Since the limiting block 215 is located on the body of the conveyor device 11, and the limiting block 215 is connected to the guide plates 211 on both sides, the guiding range of the four guide plates 211 can cover the conveyor belt area of ​​the conveyor device 11.

[0039] When the conveyor 11 carrying numerous fish pieces 12 enters the liquid nitrogen tunnel freezer 13, the fish pieces 12 undergo a micro-freezing process, resulting in a slightly frozen surface. After quick-freezing, the surface of the fish pieces 12 becomes rigid and dry. The micro-frozen fish pieces 12 then exit the liquid nitrogen tunnel freezer 13 and are moved towards the cutting device 14 by the conveyor 11. During this process, because the four guide plates 211 cover the movement path of the fish pieces 12 on the conveyor 11 and are inclined towards the channel, when the fish pieces 12 move with the conveyor 11 to the point of contact with the guide plates 211, they are guided by the inclined surfaces of the guide plates 211 and thus move into the channel.

[0040] It should be noted that in the prior art, the fish piece 12 is usually long and flat, with obvious length, width, and thickness. The aforementioned adjustment of the channel width is to adapt it to the width of the fish piece 12. Under this design, when the fish piece 12 is guided by the guide plate 211 and driven by the conveyor device 11, the fish piece 12 can only enter the channel in the width direction. This forces the fish piece 12 to be corrected in its conveying posture on the conveyor device 11, so that the length direction of the fish piece 12 is consistent with the travel direction of the conveyor belt of the conveyor device 11. Then, the fish piece 12 maintains the corrected posture in the channel and moves towards the dividing device 14 until the fish piece 12 leaves the channel and enters the dividing device 14. At this time, the user drives the dividing device 14 to divide the fish piece 12.

[0041] During the process of the dividing device 14 dividing the fish pieces 12, since the fish pieces 12 have been slightly frozen, the surface of the fish pieces 12 is rigidly shaped. As a result, the dividing device 14 can accurately divide the fish pieces 12, making the cuts flat. Furthermore, the surface of the slightly frozen fish pieces 12 is dry, which greatly reduces the surface stickiness. This allows the fish pieces 12 to move smoothly in the channel without sticking or getting stuck.

[0042] The retaining component includes two symmetrically fixed support frames 217 on the body of the conveying device 11. A slide rod 218 is rotatably connected between the two support frames 217. A support frame 219 is fixedly connected to one of the support frames 217. A servo motor 220 is fixedly connected to the slide rod 218. The output shaft end of the servo motor 220 is fixedly connected to the slide rod 218. The four guide plates 21 form three channels. Two rotating rods 222 are provided in each of the three channels. A bearing block 221 is rotatably connected to the top of the rotating rod 222. The bearing block 221 is fixedly connected to the top surface of the guide plate 21. A rubber belt 223 is fixedly connected between the two rotating rods 222 in the same channel.

[0043] Specifically, the slide bar 218 is designed with round ends and a rectangular center. Its function is to ensure that the rotating rod 222 moves with the guide plate 21, while the rotation of the slide bar 218 can still drive the rotating rod 222 to rotate synchronously.

[0044] Specifically, the bearing block 221 and the rotating rod 222 are in a limited rotation manner, meaning that the rotating rod 222 can rotate circumferentially within the bearing block 221, but it cannot detach from the bearing block 221. This ensures that the rotating rod 222 moves synchronously with the guide plate 21.

[0045] The application of rubber belt 223 here is based on the elasticity principle of its rubber material. Since the rotating rod 222 is limited and connected to the guide plate 21 through the bearing block 221, the rotating rod 222 will move synchronously with the movement of the guide plate 21. Both sides of the rubber belt 223 are connected to a rotating rod 222. Therefore, when the channel spacing is adjusted, the two guide plates 21 move closer or further away from each other. At this time, the rubber belt 223 will generate elastic deformation to ensure that the rubber belt 223 can cover the cross-sectional area of ​​the channel.

[0046] Operating principle of the component: It should be noted that the operation of the servo motor 220 is controlled by the control system of the conveying device 11, specifically, the control is adjusted according to the efficiency of the conveying device 11 in conveying the fish pieces 12. This ensures that the fish pieces 12 entering the segmentation device 14 are arranged in an orderly manner, and that the intervals between each batch of fish pieces 12 entering the segmentation device 14 are equal. In other words, the operation of the servo motor 220 is used to control the conveying and segmenting rhythm of the fish pieces 12.

[0047] While the component is in operation, the fish pieces 12 are being conveyed by the conveying device 11. At this time, the fish pieces 12 enter the channel of the guiding component and are conveyed towards the dividing device 14. If there are a large number of fish pieces 12 on the conveying device 11 at this time, and the fish pieces 12 entering the channel are arranged in a disorderly manner, if this causes the fish pieces 12 to enter the dividing device 14, it will affect the dividing effect of the fish pieces 12.

[0048] At this time, the control system of the conveying device 11 drives the servo motor 220 to run. As the servo motor 220 runs, it drives the slide bar 218 to rotate. During the rotation of the slide bar 218, the slide bar 218 drives multiple rotating rods 222 on it to rotate synchronously, thereby causing the rubber belt 223 to rotate. At this time, the control system controls the rotating rods 222 to flip vertically downwards, that is, the rubber belt 223 completely closes the channel. As the channel is closed, the rubber belt 223 will block the movement of the fish pieces 12, making... Fish pieces 12 are held on the side of the rubber belt 223 near the liquid nitrogen tunnel freezer 13. Meanwhile, more fish pieces 12 continue to flow into the channel from the conveyor 11, causing the fish pieces 12 in each channel to be arranged sequentially along their length, with the fish piece 12 in contact with the rubber belt 223 at the front. Once the fish pieces 12 in the channel are neatly arranged, the control system drives the servo motor 220 to run again, flipping the rubber belt 223 into the exit channel, thus removing the obstruction. At this point, driven by the conveyor belt of the conveyor 11, the fish pieces 12 are conveyed to the dividing device 14, where multiple fish pieces 12 that have moved out of the channel and entered the dividing device 14 are now arranged in an orderly and neat manner.

[0049] Furthermore, since the holding components are arranged in an array along the conveyor belt of the conveyor device 11, and each holding component can be operated independently, multiple holding components can divide the channel into several waiting areas. The opening and closing of each waiting area can be controlled independently, thereby controlling the rhythm of the fish pieces 12 being conveyed to the dividing device 14 for dividing, thereby improving the flexibility of the dividing device 14 in dividing the fish pieces 12.

[0050] It should be noted that as the guiding component operates, the four guide plates 21 move and adjust their spacing. During the movement of the guide plates 21, the guide plates 21 drive the rotating rod 222 to move synchronously via the bearing block 221. This causes the bearing block 221 and the rotating rod 222 to slide on the slide rod 218, and the rubber belt 223 undergoes elastic deformation. In this way, the retaining component can adjust accordingly to changes in the structure of the guiding component, ensuring that the retaining component can operate effectively in different scenarios.

[0051] In summary, the following beneficial effects can be achieved: By guiding the operation of the components, the conveying posture of the fish pieces 12 can be forcibly and accurately corrected, which greatly improves the cutting accuracy. There is no need to rework the fish pieces 12 due to cutting deviations or miscuts, which reduces the energy consumption of the cutting equipment 14 during repeated operation and achieves the energy-saving purpose of cutting the fish pieces 12. In addition, it can be adapted to the cutting and processing of fish pieces 12 of different sizes and specifications, which improves its versatility and adaptability.

[0052] By using surface micro-freezing instead of complete freezing in the existing technology, the energy consumption of the liquid nitrogen tunnel freezer 13 is greatly reduced while meeting the requirements for dividing and shaping the fish pieces 12, thus achieving energy saving and consumption reduction. The surface of the micro-frozen fish pieces 12 is dry and rigidly shaped, eliminating surface stickiness and avoiding sticking and jamming during the conveying and dividing process. At the same time, it can ensure that the cut is flat and smooth during the dividing process, greatly improving the quality after dividing.

[0053] By operating the components, the fish block 12 segmentation and conveying channel is divided into multiple independent waiting areas, and the opening and closing can be controlled individually. The fish block 12 arrangement is organized so that the fish block 12 enters the segmentation equipment 14 in an orderly manner, ensuring that the segmentation operation of the fish block 12 can be carried out stably. The conveying and segmentation rhythm of the fish block 12 can be flexibly adjusted to adapt to different production needs, and the processing flexibility of the equipment is greatly improved.
