Description

Technical Field

[0001] This invention relates to the field of automated equipment technology, and in particular to a preliminary processing device for ribbonfish. Background Technology

[0002] Ribbonfish is a marine fish widely distributed in temperate and tropical waters. Its flesh is tender and delicious, rich in protein, unsaturated fatty acids, and various minerals and vitamins. It has high nutritional and edible value and is one of the important economic fish species along my country's coast. It is also an important raw material for the catering and food processing industries.

[0003] In the sale of ribbonfish, besides whole ribbonfish, there are also ribbonfish that have had their internal organs and fins removed, cut into pieces, and then frozen for sale. For the latter, preliminary processing of the ribbonfish is required, including fin removal, gutting, and cutting into pieces. Currently, the preliminary processing of ribbonfish mainly involves the following methods: The first method involves manual processing. Operators use knives to remove the dorsal and pectoral fins of the ribbonfish one by one, then open the belly to remove the internal organs, and finally cut the fish into pieces according to specifications. However, ribbonfish have large mouths and sharp teeth with barbs, making it extremely easy to cut the operator's hands during manual processing, posing a significant safety hazard. Furthermore, manual processing is inefficient, labor-intensive, and the cutting techniques and standards used by different operators are difficult to standardize, resulting in ribbonfish pieces of inconsistent size and quality, making it difficult to meet the needs of large-scale, standardized production.

[0004] The second type is semi-mechanized, single-function processing. For example, there are devices specifically designed for removing the internal organs of ribbonfish, which use motors to drive rotating rollers and a gutting cutter to automatically gut the fish, and then use a scraper to remove the internal organs. There are also specialized ribbonfish segmenting machines that use a conveyor belt and a cutting unit to automatically segment the fish. However, these types of equipment usually only have a single processing function, and the transfer of ribbonfish between different devices still requires manual intervention. The process is not well connected, and the overall processing efficiency is still not high.

[0005] In summary, existing ribbonfish primary processing technologies suffer from problems such as high labor intensity, low efficiency, cumbersome procedures, inconsistent standardization, and lack of sorting and collection capabilities. Therefore, it is necessary to design an integrated primary processing system that automates the entire process of ribbonfish transportation, clamping, identification, fin removal, viscera removal, cutting, and sorting and collection, thereby improving both processing efficiency and optimizing processing results. Summary of the Invention

[0006] The purpose of this invention is to provide a preliminary processing device for ribbonfish to solve the technical problem of balancing improved processing efficiency and optimized processing results.

The ribbonfish cutting assembly includes at least a guillotine for cutting the ribbonfish body and a drive structure for driving the guillotine to reciprocate longitudinally relative to the fish body.

[0008] In an optional embodiment of the invention, the driving element is a first motor connected to the roller; and The pushing component also includes a pair of sliding lifting structures that each cooperate with each stick in a one-to-one manner; Each of the sliding lifting structures includes a pair of sliding seats connected to each roller, and at least one guide rod that slides with each sliding seat; and each guide rod is fixed to the base frame.

[0009] In an optional embodiment of the invention, the end face of the finning plate facing the saw blade has a V-shaped cut; and The saw blade is also connected to a second motor for driving its rotation, and the frame of the second motor is connected to a first servo motor, which is used to drive the second motor to drive the saw blade to rotate synchronously.

[0010] In an optional embodiment of the present invention, the fish clamping plate is further connected to a first linear drive module for driving it to make linear movements relatively closer to and further away from the fin-removing plate. The first linear drive module includes a reciprocating rod connected to the fish-clamping plate, a connector fixedly connected to the reciprocating rod, a reciprocating wheel mating with the connector, and a second servo motor for driving the reciprocating wheel to rotate; wherein The connector has a waist-shaped groove, and the reciprocating wheel is provided with a protruding connecting post that extends into the waist-shaped groove; the long axis of the waist-shaped groove is perpendicular to the linear movement direction of the fish clamp.

[0011] In an optional embodiment of the present invention, the fish clamping plate is provided with a plurality of rollers spaced apart along the conveying direction of the ribbonfish on the side end face facing the carrier plate.

[0012] In an optional embodiment of the present invention, the power structure includes a third servo motor connected to the flaring blade, and a second linear drive module for driving the third servo motor to make linear movements relatively close to and away from the ribbonfish. The second linear drive module adopts a linear lead screw module.

[0013] In an optional embodiment of the present invention, the drive structure includes a pair of crank linkage structures connected to the knife gate; Each of the aforementioned crank linkage structures includes a linkage rod connected to the gate, a support block that slides with the linkage rod, a crank connecting rod connected to the end of the linkage rod away from the gate, a crank rocker arm, and a fourth servo motor connected to the crank rocker arm.

[0014] In an optional embodiment of the present invention, the ribbonfish preliminary processing device further includes a pressing component disposed above the carrier plate for pressing the ribbonfish onto the carrier plate; The pressing assembly includes a support rod fixed on the base frame, a pair of pressing rods that rotatably engage with the end face of the support rod facing the carrier plate, and a pressing wheel located on the end face of each pressing rod facing away from the support rod.

[0016] In an optional embodiment of the present invention, the ribbonfish preliminary processing device further includes a fish guide plate arranged at an incline between the lower part of the gate and the upper part of the feed cylinder.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects: The ribbonfish preliminary processing device of the present invention integrates the processes of ribbonfish conveying, clamping, fin removal, viscera removal, and dicing into the same equipment.

[0019] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0020] Please see Figures 1 to 11 As shown, this embodiment provides a preliminary processing device for ribbonfish, including at least a base frame 1, a carrier plate 11 mounted on the base frame 1 for supporting the ribbonfish, a pushing component 2 for driving the ribbonfish to move on the carrier plate 11, and a fin-removing component 4, an internal organ removal component 6, a ribbonfish cutting component 9, and a collecting component 10 arranged sequentially along the conveying direction of the ribbonfish. The components are arranged on the base frame 1 according to the processing sequence of the ribbonfish, forming a complete automated preliminary processing production line for ribbonfish.

[0021] The base frame 1, serving as the supporting skeleton of the entire processing device, is constructed from welded or bolted metal profiles, possessing sufficient structural strength and rigidity to support and secure the various functional components. The carrier plate 11 is a flat structure extending along the conveying direction of the ribbonfish, used to support the ribbonfish body during processing. The ribbonfish enters from one end of the processing device (feed end) and moves along the length of the carrier plate 11 under the pushing action of the pushing component 2. It sequentially undergoes fin removal by the fin removal component 4, viscera removal by the viscera removal component 6, and dicing by the ribbonfish dicing component 9. Finally, the collecting component 10 completes the classification and collection of different parts.

[0022] Regarding the pushing component 2, its power conveying unit, which transports the ribbonfish on the carrier plate 11, is used to push the ribbonfish from the feeding end into the interior of the processing device and ensures continuous and stable conveying of the ribbonfish throughout the processing. The pushing component 2 includes at least a pair of rollers spaced apart and a pair of driving members for driving the rotation of the pair of rollers respectively. Specifically, the pair of rollers includes a front roller 25 and a rear roller 28. The front roller 25 is driven by a first motor 27, and the rear roller 28 is driven by a first motor 29. Both the first motor 27 and the first motor 29 are DC geared motors, and their output ends are respectively connected to the corresponding rollers for transmission. It should be noted that, for the pair of rollers in this embodiment, their surfaces may be covered with brushes, which provide a pushing effect on the ribbonfish.

[0023] The pushing assembly 2 also includes a pair of sliding lifting structures 26 that each roller is paired with. Each sliding lifting structure 26 includes a pair of sliding seats 23 connected to each roller, and at least one guide rod 22 that slides with each sliding seat 23. The guide rod 22 is fixed to the base frame 1. Specifically, one end of the guide rod 22 is fixedly connected to an optical axis fixing seat 21, which is fixed to the outer surface of the base frame 1. A limit ring 24 is also provided on the guide rod 22 to constrain the lifting range of the sliding seat 23 on the guide rod 22. The sliding seat 23 is sleeved on the outer surface of the guide rod 22 and can slide along the axial direction of the guide rod 22. The roller is fixedly connected to the sliding seat 23 and rises and falls together with the sliding seat 23.

[0024] When the ribbonfish reaches the front roller 25, the first motor 27 drives the roller 25 to rotate, using the friction between the roller and the surface of the ribbonfish to push the ribbonfish into the processing device. The roller 25 slides with the guide rod 22 via the sliding seat 23, providing elastic lifting functionality. Specifically, when the ribbonfish is large, it exerts an upward thrust on the roller 25, causing the sliding seat 23 to automatically move upward along the guide rod 22, allowing the roller 25 to conform to the fish body and compact it for transport. The limiting ring 24 restricts the lowering limit of the sliding seat 23, preventing the ribbonfish from getting stuck due to the roller 25 being too low. This sliding lifting structure design enables adaptive transport of ribbonfish of different sizes. After the ribbonfish has undergone finning and evisceration, the rear roller 28 continues to push it towards the ribbonfish cutting assembly 9, ensuring the continuity of processing.

[0025] The fin removal assembly 4 is used to remove the dorsal fin and pectoral fin of the ribbonfish. The fin removal assembly 4 includes at least a fin-removing plate 45 located at one end of the length direction of the carrier plate 11, a saw 41 located next to the fin-removing plate 45, and a fish clamping plate 32 located at the other end of the length direction of the carrier plate and opposite to the fin-removing plate 45.

[0026] The saw blade 41 uses a circular saw blade to cut an opening at the junction of the ribbonfish's head and fins. The saw blade 41 is connected to a second motor 43, which is a DC geared motor, to drive its rotation. A first servo motor 44 is connected to the frame 42 of the second motor 43, driving the second motor 43 to synchronously rotate the saw blade 41. The frame 42 of the second motor 43 is fixedly connected to the first servo motor 44. The first servo motor 44 can drive the frame 42 to rotate, thereby causing the second motor 43 and the saw blade 41 to swing as a whole. The fin-removing plate 45 has a V-shaped cut on its end face facing the saw blade 41. The V-shaped cut is used to catch the fins as the ribbonfish is transported forward, causing the fins to separate from the fish.

[0027] The design of the fin-removing plate 45 and the fish-clamping plate 32, arranged opposite each other, is used to clamp and fix the ribbonfish during processing, preventing it from shifting or jumping during fin removal and visceration, thus ensuring the precision of each processing step. Specifically, the fish-clamping plate 32 has a plate-like structure, extending along the ribbonfish conveying direction and located at one side end along the length of the carrier plate. Multiple rollers 31 are spaced apart on the side end of the fish-clamping plate 32 facing the carrier plate 11 along the ribbonfish conveying direction. The rollers 31 can rotate freely, and their surfaces contact the ribbonfish body. While the fish-clamping plate 32 and the fin-removing plate 45 cooperate to clamp the ribbonfish, the ribbonfish is allowed to slide along the conveying direction, flexibly conforming to the fish body and preventing the fish meat from being squeezed and deformed.

[0028] A fish-clamping plate 32 is positioned between a pair of rollers, and is also connected to a first linear drive module for driving it to move relatively closer to and away from the fin-removing plate 45. The first linear drive module includes a reciprocating rod 34 connected to the fish-clamping plate 32, a connector 36 fixedly connected to the reciprocating rod 34, a reciprocating wheel 33 mating with the connector 36, and a second servo motor 35 for driving the reciprocating wheel 33 to rotate. The reciprocating rod 34 is arranged perpendicular to the direction of fish transport. The reciprocating wheel 33 is fixedly connected to the middle surface of the reciprocating rod 34, and the second servo motor 35 is located below the reciprocating wheel 33. The connector 36 has a waist-shaped groove 361, and the reciprocating wheel 33 has a protruding connecting post 331 extending into the waist-shaped groove 361. The long axis of the waist-shaped groove 361 is perpendicular to the linear movement direction of the fish-clamping plate 32. Specifically, the connecting post 331 is positioned eccentrically on the reciprocating wheel 33. When the reciprocating wheel 33 rotates, the connecting post 331 slides in the waist-shaped groove 361, causing the connecting piece 36 and the reciprocating rod 34 to reciprocate along a direction perpendicular to the long axis of the waist-shaped groove 361 (i.e., the linear motion direction of the fish clamping plate 32). The long axis of the waist-shaped groove 361 is perpendicular to the linear motion direction of the fish clamping plate 32, thus converting the rotational motion of the reciprocating wheel 33 into the linear reciprocating motion of the fish clamping plate 32.

[0029] Based on the above structure, the ribbonfish preliminary processing device in this embodiment also includes a camera 71 for identifying ribbonfish entering the area formed by the clamping plate 32 and the fin-removing plate 45. The camera 71 adopts an industrial-grade image acquisition module with high resolution and frame rate, and can acquire image information of the ribbonfish in real time during the ribbonfish conveying process. When the camera 71 identifies that the ribbonfish has entered the processing position, the second servo motor 35 drives the reciprocating wheel 33 to rotate. The eccentric connecting column on the reciprocating wheel 33 slides in the waist-shaped groove 361 of the connecting member 36, converting the rotational motion of the reciprocating wheel 33 into the linear reciprocating motion of the reciprocating rod 34. The reciprocating rod 34 drives the clamping plate 32 to move closer to the ribbonfish (i.e., closer to the fin-removing plate 45), clamping and fixing the ribbonfish body between the clamping plate 32 and the fin-removing plate 45. The roller 31 on the clamping plate 32 contacts the surface of the ribbonfish in the clamping state. Since the roller 31 can rotate flexibly, the ribbonfish can still move along the conveying direction under the pushing action of the pushing component 2 under the rolling support of the roller 31. This "clamping without locking" design ensures that the ribbonfish is fixed in position during processing while also enabling continuous transport of the ribbonfish.

[0030] Based on the above structure, after the ribbonfish is fixed by the clamping plate 32 and the fin-removing plate 45, the camera 71 detects the position of the ribbonfish's head node. According to the recognition result of the camera 71, the first servo motor 44 is controlled to rotate, causing the frame 42 of the second motor 43 to swing, driving the saw blade 41 to move to the connection point between the ribbonfish's head and fin. The second motor 43 drives the saw blade 41 to rotate at high speed, quickly cutting to form an opening at the connection point between the ribbonfish's head and fin.

[0031] Subsequently, the ribbonfish continues to be conveyed forward under the pushing of the pushing component 2 and the rolling support of the rollers 31 of the clamping plate 32. Because the ribbonfish is clamped by the clamping plate 32 and the fin-removing plate 45, the fins are tightly attached to the fin-removing plate 45. As the ribbonfish moves forward, the fins enter the V-shaped cut 451 of the fin-removing plate 45, are blocked by the edge of the V-shaped cut, and gradually separate from the fish body, ultimately being completely removed. This two-step fin removal method, which involves first cutting an opening and then mechanically removing the fins through a V-shaped cut, can more accurately remove the fins compared to simply relying on pulling or a single blade cutting, avoiding damage to the fish meat and reducing fish meat loss.

[0032] Based on the above, it should be noted that the preliminary processing device for ribbonfish in this embodiment also includes a pressing assembly 5 disposed above the carrier plate 11. This assembly is used to press the ribbonfish body onto the carrier plate 11 from above after the ribbonfish is clamped by the clamping plate 32 and the fin-removing plate 45, preventing the ribbonfish from lifting or jumping due to force during processing. Specifically, the pressing assembly 5 includes a support rod 51 fixed to the base frame 1, a pair of pressing rods 52 rotatably engaged with the end face of the support rod 51 facing the carrier plate, and a pressing wheel 53 disposed on the end face of each pressing rod 52 facing away from the support rod 51. The support rod 51 is arranged parallel to the ribbonfish conveying direction. One end of the pressing rod 52 is rotatably connected to the support rod 51, and a torsion spring is installed between the pressing rod 52 and the support rod 51. The pressing wheel 53 is rotatably connected to the other end of the pressing rod 52 (i.e., the end face away from the support rod 51). When the ribbonfish is clamped by the clamping plate 32 and the finning plate 45, the fish body may slightly warp under the clamping force. The pressing roller 53 of the pressing assembly 5 automatically applies elastic pressure downwards under the action of a torsion spring, pressing the ribbonfish body onto the carrier plate 11. The torsion spring provides elastic pressure, allowing the pressing roller 53 to automatically adjust the pressing height according to the thickness of the ribbonfish body, ensuring both pressing effectiveness and avoiding excessive squeezing and damage to the fish meat. The pressing roller 53 can rotate freely, pressing the ribbonfish without obstructing its forward transport.

[0033] Next, we will describe the viscera removal component 6, which is used to cut open the belly of the ribbonfish and remove the internal organs. The viscera removal component 6 includes at least a flaring blade 61 for cutting open the ribbonfish's belly, and a power structure for driving the flaring blade 61. The power structure includes a third servo motor 62 connected to the flaring blade 61, and a second linear drive module 63 for driving the third servo motor 62 to make linear movements relatively close to and away from the ribbonfish. The output end of the third servo motor 62 is connected to the flaring blade 61 for driving the flaring blade 61 to rotate around its axis to adjust the blade angle. The second linear drive module 63 is fixedly connected to one side of the outer surface of the third servo motor 62.

[0034] In this embodiment, the second linear drive module 63 adopts a linear lead screw module. The linear lead screw module 63 includes a lead screw base 672 disposed on the outer surface of the base frame 1. A lead screw 673 is movably connected to the middle of the lead screw base 672. One end of the lead screw 673 is provided with a lead screw bearing wheel 671, and the other end of the lead screw 673 is fixedly connected to a motor bracket 674. A stepper motor 75 is fixedly connected to the motor bracket 674. The output end of the stepper motor 675 is connected to the lead screw 673 for transmission. When the ribbonfish is clamped and transported to the viscera removal station, the third servo motor 62 rotates, causing the belly-expanding knife 61 to rotate to an angle adapted to the shape of the ribbonfish. At the same time, the motor shaft of the stepper motor 75 drives the lead screw 673 to rotate. The thread on the surface of the lead screw 673 engages with the lead screw base 672, converting the rotational motion of the lead screw 673 into linear motion of the lead screw base 672 along the lead screw axis. The lead screw base 672 drives the third servo motor 62 and the evisceration knife 61 to move forward (i.e., towards the ribbonfish) or backward (i.e. away from the ribbonfish), thereby achieving precise adjustment of the evisceration depth of the evisceration knife 61.

[0035] The gutting knife 61, with its angle and depth adjustable, cuts along the belly of the ribbonfish as it is transported forward, opening the abdomen. After gutting, the special blade-shaped structure of the gutting knife 61 (such as a gutting structure) expands the belly, exposing and removing the internal organs. The ribbonfish continues to be transported forward, completing the automatic removal of the internal organs. This adaptive visceration design, which allows for rotation and adjustable depth, enables the gutting depth and angle to be personalized according to the actual size of the ribbonfish, ensuring thorough removal of the internal organs while avoiding excessive cutting and damage to the fish meat.

[0036] The ribbonfish cutting assembly 9 is used to cut ribbonfish that have been defining and gutted into pieces according to a predetermined size. The ribbonfish cutting assembly 9 includes at least a guillotine 92 for cutting the body of the ribbonfish, and a drive structure for driving the guillotine 92 to reciprocate longitudinally relative to the body of the fish.

[0037] The drive structure includes a pair of crank linkage structures connected to the gate 92. Each crank linkage structure includes a linkage rod 93 connected to the gate 92, a support block 91 that slides with the linkage rod 93, a crank connecting rod 94 connected to the end of the linkage rod 93 away from the gate 92, a crank rocker arm 95 connected to the crank connecting rod 94, and a fourth servo 96 connected to the crank rocker arm 95.

[0038] Specifically, the ribbonfish cutting assembly 9 includes a servo bracket 97 disposed on the outer surface of the base frame 1. A fourth servo 96 is disposed on the outer surface of the servo bracket 97. Two sets of fourth servos 96 are configured, located on opposite sides of the ribbonfish conveying path. Each set of fourth servos 96 has a crank arm 95 fixedly connected to its output end. One end of each crank arm 95 is connected to a crank connecting rod 94. One end of the crank connecting rod 94 (i.e., the end furthest from the crank arm 95) is connected to a linkage rod 93. A support block 91 is movably connected through the outer surface of the linkage rod 93, and the support block 91 is fixed to the base frame 1. One end of the linkage rod 93 (i.e., the end furthest from the crank connecting rod 94) is connected to a gate 92.

[0039] Based on the above structure, after the fourth servo motor 96 is activated, its output end drives the crank rocker arm 95 to rotate. The crank rocker arm 95 transmits the rotational motion to the linkage rod 93 through the crank connecting rod 94. Under the guidance and constraint of the support block 91, the linkage rod 93 converts the rotational motion into linear reciprocating motion in the vertical direction. The two sets of symmetrically arranged fourth servo motors 96, crank rocker arms 95, crank connecting rods 94 and linkage rods 93 cooperate with the support block 91 to jointly drive the guillotine 92 to make stable linear reciprocating motion along the vertical guide rail.

[0040] When the defining and gutting ribbonfish are conveyed to the working area of ​​the ribbonfish cutting assembly 9, the gate 92 moves downward under the drive of the crank linkage structure, cutting the ribbonfish body. After cutting, the gate 92 moves upward to reset, and the ribbonfish continues to be conveyed forward for a distance. Then, the gate 92 cuts downward again, repeating this process to cut the ribbonfish into equal-length pieces. This linear reciprocating gate cutting method, compared to manual or drum-type cutting, ensures the consistency of the piece size and the smoothness of the cut, improving the quality and standardization of the ribbonfish pieces. A collection assembly is used to classify and collect the cut ribbonfish pieces according to different parts such as the head, tail, and flesh.

[0041] The collection assembly 10 includes a feed cylinder 101 and a fifth servo motor 102 for driving the feed cylinder 101 to rotate. The feed cylinder 101 is provided with a partition 104 that divides the feed cylinder 101 into at least two compartments, and different compartments can correspond to different fish parts.

[0042] Specifically, the collecting component 10 includes a turntable servo bracket 103 fixed to the outer surface of the base frame 1. A fifth servo motor 102 is fixedly connected to the turntable servo bracket 103. A material cylinder 101 is located at the output end of the fifth servo motor 102. The material cylinder 101 has a disc-shaped structure, and its interior is divided into multiple independent compartments by partitions. A camera 71 performs visual recognition on the conveyed ribbonfish pieces, accurately distinguishing different parts such as the fish head, tail, and flesh. The recognition signal is transmitted to the control system of the collecting component 10. After receiving the control signal, the fifth servo motor 102 drives the material cylinder 101 to rotate at a specific angle, aligning the corresponding compartment with the discharge port of the guide plate 82. The ribbonfish pieces slide off the guide plate 82 and enter the corresponding compartment of the material cylinder 101.

[0043] As the ribbonfish pieces are continuously conveyed and identified, the fifth servo motor 102 continuously adjusts the rotation angle of the feed cylinder 101 based on the identification results, ensuring that ribbonfish pieces from different parts are accurately delivered into the corresponding compartments for classified collection. This machine vision-based automatic classification and collection method achieves fully automated classification of different parts of the ribbonfish, avoiding the inefficiency and cross-contamination risks of manual sorting.

[0044] Based on the above, it is also necessary to explain that the camera 71 in this embodiment continuously collects images of the ribbonfish during the transport process. It is connected to the upper-level control system and analyzes the collected images to identify features such as the ribbonfish's outline, head position, tail position, body width, and length. The camera 71 in this embodiment mainly functions in the following three ways: First, during the fin removal stage, the camera 71 detects the head node position of the ribbonfish, providing a precise cutting position signal to the first servo motor 44, ensuring that the saw 41 accurately cuts an opening at the junction of the head and fins; Second, during the viscera removal stage, the camera 71 identifies the ribbonfish's body width, providing control parameters to the third servo motor 62 and the stepper motor 75, ensuring that the angle and depth of the gutting knife 61 match the ribbonfish's body shape; Third, during the sorting and collection stage, the camera 71 identifies the cut ribbonfish pieces, accurately distinguishing between different parts such as head pieces, tail pieces, and meat pieces, and transmits the identification signal to the collection component 10. It should be noted that in this embodiment, not just one camera 71 is provided, but multiple cameras are provided at intervals along the direction in which the ribbonfish is transported on the carrier plate 11, for example, but not limited to three.

[0045] Finally, it is necessary to note that an inclined fish guide plate 82 is provided between the lower part of the gate 92 and the upper part of the feed cylinder 101, and a fish guide plate 82 is provided between the fish guide plate 82 and the gate 92. Next, it should be noted that the preliminary processing device for ribbonfish in this embodiment also includes a conveyor plate 81, which has a flat structure and is arranged inclined or horizontally on the base frame 1. A guide plate 82 is fixedly connected to one side of the outer surface of the conveyor plate 81 (i.e., the end of the conveyor plate 81) and is arranged inclined to guide the cut ribbonfish pieces to the collection assembly 10. The rear roller 28 places the ribbonfish that has been defining and gutted onto the conveyor plate 81 and continues to transport it forward. The ribbonfish moves forward on the conveyor plate 81 by the pushing force of the roller 28 and its own gravity (if the conveyor plate 81 is arranged inclined). When the ribbonfish reaches the end of the conveyor plate 81, the guide plate 82 guides the ribbonfish to the working area of ​​the ribbonfish cutting assembly 9. After the ribbonfish is cut into pieces, the cut ribbonfish pieces slide down the guide plate 82 to the collection assembly 10.

[0046] In summary, the specific workflow of the ribbonfish preliminary processing device in this embodiment is as follows: The ribbonfish enters from the feed end, and the first motor 27 drives the roller 25 to rotate, pushing the ribbonfish into the device. The roller 25 slides with the guide rod 22 through the sliding seat 23, providing elastic lifting and lowering functions to adapt to ribbonfish of different sizes. The camera 71 detects the ribbonfish entering, and the second servo motor 35 drives the reciprocating wheel 33 to rotate, which in turn drives the fish clamping plate 32 to clamp the ribbonfish body through the reciprocating rod 34. The rollers 31 on the fish clamping plate 32 flexibly conform to the fish body to prevent the fish meat from being squeezed and deformed. The pressing component 5 presses and fixes the ribbonfish from above. The camera 71 detects the head node of the ribbonfish and controls the first servo motor 44 to drive the second motor 43 and the saw blade 41 to swing to the working position. The second motor 43 drives the saw blade 41 to rotate at high speed, cutting an opening at the junction of the fish head and the fin. The ribbonfish then continues to move forward, and the fins are removed by the V-shaped cut of the fin-removing plate 45. Camera 71 identifies the width and shape of the ribbonfish. The third servo motor 62 adjusts the angle of the belly-expanding blade 61, and the stepper motor B675 adjusts the belly-opening depth via a linear screw module 63. The belly-expanding blade 61 cuts along the ribbonfish's belly, opening it and removing the internal organs. The rear roller 28 transports the ribbonfish to the ribbonfish cutting assembly 9. The fourth servo motor 96 drives the gate blade 92 in a longitudinal reciprocating motion via a crank-driven linkage, cutting the ribbonfish into equal-length pieces. Camera 71 identifies the type of part of the ribbonfish piece, and the fifth servo motor 102 drives the material cylinder 101 to rotate at a specific angle, sending ribbonfish pieces from different parts into their corresponding compartments for sorting and collection. The entire processing is fully automated under the unified coordination of the control system, requiring no manual intervention.
