DETAILED DESCRIPTION

[0019] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0020] The embodiment of the present application provides a horse face fish processing device, which can solve the technical problems of low production efficiency and high work intensity in the related art.

[0021] Referring to Figure 1 and Figure 2The fish head separation mechanism 1 can separate the fish head and the fish body of the horseface fish; the internal organ removal mechanism 2 is connected to the fish head separation mechanism 1; in the internal organ removal process, the horseface fish is gradually dissected and cut open, and the internal organ removal is completed; the skin and flesh separation mechanism 3 is connected to the side, away from the fish head separation mechanism 1, of the internal organ removal mechanism 2, and the skin and flesh separation mechanism 3 comprises a separation support frame 31, the separation support frame 31 is provided with a first conveying part 32 and a fish skin cutting part 33, the fish skin cutting part 33 is arranged on the side, away from the internal organ removal mechanism 2, of the first conveying part 32; the separation support frame 31 is further provided with an inclined rolling roller 34, the inclined rolling roller 34 is arranged on the side, close to the fish skin cutting part 33, of the first conveying part 32, and the inclined rolling roller 34 and the first conveying part 32 are arranged in a spaced manner along the direction perpendicular to the plate surface of the first conveying part 32, the inclined rolling roller 34 and the first conveying part 32 cooperate to extrude the fish body, and the fish skin cutting part 33 separates the fish skin and the fish flesh. It should be understood that the inclined rolling roller 34 can comprise a driving motor and a rotating shaft connected to the driving shaft of the driving motor, the rotating shaft extends along the direction perpendicular to the length direction of the first conveying part 32, that is, the width direction of the separation support frame 31, and a pressing column coaxial with the rotating column shaft can be sleeved on the outer periphery of the rotating column, and the pressing column is preferably made of silica gel to reduce damage to the fish skin during rolling.

[0022] The fish head separation mechanism 1 and the internal organ removal mechanism 2 are sequentially connected, the fish head and the internal organ of the horseface fish can be removed respectively, when the fish enters the skin and flesh separation mechanism 3, the extrusion of the inclined rolling roller 34 and the first conveying part 32 can make the thick and tough horseface fish flatly adhere to the conveying belt of the first conveying part 32, so that the fish skin can more closely adhere to the knife surface of the fish skin cutting part 33 when passing through the fish skin cutting part 33, the separation of the fish flesh and the fish skin is completed, and preferably, the inclined rolling roller 34 is always in a rotating state when extruding the horseface fish with the first conveying part 32, when the inclined rolling roller 34 rotates, the outer periphery surface of the pressing column continuously rolls with the contact point of the fish body, can apply uniform and continuous pressure to different parts of the fish body, and reduce the problem of local excessive pressure leading to fish flesh damage during static extrusion. In the embodiment of the application, the horseface fish processing device is connected in sequence by the fish head separation mechanism 1, the internal organ removal mechanism 2 and the skin and flesh separation mechanism 3, and a full-process automatic processing line from the fish head to the skin and flesh separation is constructed, the manual operation steps are reduced, the processing amount per unit time is improved, and the strength of repeated labor of workers is reduced. It should be understood that the horseface fish skin is thick and tough, and the skin and flesh adhere closely, which is the key to manual and ordinary device separation, the extrusion of the inclined rolling roller 34 and the first conveying part 32 can better overcome this problem, and solve the problems of large part of horseface fish processing relying on manual, low production efficiency and large working strength in the related art. In the embodiments of the present application, the height direction of the separation support frame 31 on the ground can be regarded as the height direction of the whole horseface fish processing device. The first conveying part 32 can include a transmission roller and a transmission belt connected to the transmission roller, and the transmission roller is driven to rotate by a motor to drive the transmission belt to move. In addition, the inclined roller 34 can be adjusted in height in the height direction, specifically, a plurality of groups of mounting holes are arranged on the separation support frame 31 along the height direction of the separation support frame 31, and the rotating shaft of the inclined roller 34 can be matched with the mounting holes at different heights to realize height adjustment. When the horseface fish needs to be processed, the horseface fish can be divided into different batches according to the size of the horseface fish. During operation, the distance between the inclined roller 34 and the transmission belt is adjusted according to the size of the horseface fish in different batches, so that the appropriate extrusion force can be obtained for both large fish and small fish, which can ensure that the fish body is flat and close to the conveying belt, and avoid excessive extrusion damage to the fish meat. The horseface fish processing device in the embodiments of the present application can be applied to horseface fish with a body length of 18-28 cm. Further, referring to Figure 13 As shown in the figure, the fish skin cutting part 33 can include a blade 331 and a guide groove 332 fixed to the blade 331, and the guide groove 332 and the blade 331 are both installed on the separation support frame 31. The blade 331 can have a certain gap with the transmission belt, so that when the blade 331 is used to cut the fish skin, the cut fish skin is located below the blade 331, and the cut fish meat is located above the blade 331. After the fish skin and fish meat are completely separated, the fish meat falls from the guide groove 332 into the fish meat collecting frame below the guide groove 332.

[0023] Referring to Figure 3 and Figure 5As shown, in some alternative embodiments, the fish head separating mechanism 1 comprises a fish head support frame 11 connected to the internal organ removing mechanism 2, the fish head support frame 11 is installed with: a second conveying part 12, the second conveying part 12 comprises a fish head conveying belt 121 and a fish body conveying belt 122, the fish head conveying belt 121 and the fish body conveying belt 122 are arranged along the width direction of the fish head support frame 11; the second conveying part 12 further comprises a plurality of conveying rollers 123 arranged along the length direction of the second conveying part 12, the fish head conveying belt 121 and the fish body conveying belt 122 are connected to the plurality of conveying rollers 123, so that the plurality of conveying rollers 123 drive the fish head conveying belt 121 and the fish body conveying belt 122 to move synchronously; a separating part arranged between the second conveying part 12 and the internal organ removing mechanism 2, the separating part is provided with a fish head falling hole 132 and a fish body containing groove 131, the fish head falling hole 132 and the fish body containing groove 131 are arranged along the length direction of the second conveying part 12, the fish head falling hole 132 is connected to the fish head conveying belt 121, and the fish body containing groove 131 is connected to the fish body conveying belt 122; a cutting piece 14 installed between the fish head conveying belt 121 and the fish body conveying belt 122, the cutting piece 14 is installed on one side of the second conveying part 12 close to the separating part. It should be understood that the fish head conveying belt 121 and the fish body conveying belt 122 are arranged along the width direction of the fish head support frame 11, and the interval between the fish head conveying belt 121 and the fish body conveying belt 122 is usually small, which is convenient to avoid the cutting piece 14. In the embodiment of the application, the conveying rollers 123 are provided as two, and the length direction of each conveying roller 123 is perpendicular to the extension direction of the fish body conveying belt 122. Preferably, the cutting piece 14 is fixed on the conveying roller 123 close to the internal organ removing mechanism 2, and the cutting piece 14 and the conveying roller 123 are coaxially arranged. By arranging the separating part, the fish head and the fish body can be better separated in the "assembly line" work. When the fish is placed horizontally on the second conveying part 12 until the fish head and the fish body are separated by the cutting piece 14, the fish head and the fish body are respectively put into the fish head falling hole 132 and the fish body containing groove 131, the fish head can fall into the fish head collecting frame 16 installed below, which is convenient for the workers to arrange and collect, and the fish body continues to enter the internal organ removing mechanism 2 of the next stage. In the embodiment of the application, the two conveying rollers 123 drive the fish head conveying belt 121 and the fish body conveying belt 122 to move synchronously, which cooperates with the horizontal placement of the fish body to ensure the stability of the fish body position when the cutting piece 14 cuts, and reduces the occurrence of incomplete cutting or damage to the fish body caused by deviation.Furthermore, the cutting component 14 uses a saw blade with serrations on its outer edge. There can be a certain angle difference between the serrated surface and the main surface of the saw blade, which is set to 15~30°. The thickness of the serrations and the saw blade is set to 2mm. At this time, the inclined serrated surface forms a bevel cutting effect. Compared with the vertical serrations, it can more easily cut into the thick and tough skin of the filefish, reduce cutting resistance, avoid the problem of the saw blade getting stuck or needing to cut repeatedly, and improve the success rate of a single cut.

[0024] See Figure 6 As shown, preferably, a splash guard 17 is installed on the fish head support frame 11 near the cutting part 14. The splash guard 17 covers the periphery of the cutting part 14. When cutting the horse mackerel, the fish tissue, blood and other substances are easily splashed as the saw blade rotates at high speed. The splash guard 17 can effectively block the splashes, avoid injuring the surrounding workers and reduce the risk of operation safety.

[0025] See Figure 7 and Figure 14As shown, in some optional embodiments, a preliminary attitude adjustment component 15 is connected to the side of the fish body receiving groove 131 near the fish body conveyor belt 122; the preliminary attitude adjustment component 15 includes an inclined baffle 151, one end of which is connected to the first sidewall of the fish body receiving groove 131, and the other end extends in a direction away from the fish body receiving groove 131. The surface of the inclined baffle 151 is perpendicular to the surface of the fish body conveyor belt 122, and the length direction of the inclined baffle 151 forms an angle with the length direction of the fish body conveyor belt 122. The orthographic projection of at least a portion of the inclined baffle 151 is located on the... Inside the fish body conveyor belt 122; the preliminary posture adjustment component 15 also includes a wedge block 152, which is connected to the second side wall of the fish body receiving groove 131. The first side wall and the second side wall are arranged opposite to each other. The wedge block 152 and the inclined baffle 151 form a partition groove, which communicates with the fish body receiving groove 131. Along the direction perpendicular to the length of the fish body conveyor belt 122, the width of the partition groove on the side away from the fish body receiving groove 131 is greater than the width of the partition groove on the side closer to the fish body receiving groove 131, and the height of the bottom panel of the partition groove is higher than the height of the bottom panel of the fish body receiving groove 131. That is to say, after the filefish completes the separation of the head and body, the fish body can first enter the preliminary posture adjustment component 15 for adjustment. The purpose of this adjustment is to turn the fish, which is placed horizontally on the fish body conveyor belt 122, into a vertical position as much as possible before entering the next stage of the work area. In this embodiment, the inclined baffle 151 is located on the side of the wedge block 152 that is away from the cutting member 14, that is, the inclined baffle 151 can contact the fish tail. The specific steps for the initial adjustment of the fish body posture in this embodiment can be as follows: after the fish tail enters the interval groove and touches the inclined baffle 151, under the obstruction of the inclined baffle 151, the moving speed of the fish tail gradually decreases from the moving speed of the fish body near the head end. The fish body near the head end can be called the head end. When the fish body moves to the side of the fish body conveyor belt near the wedge block 152, the head end enters the upper surface of the wedge block 152 first due to the height difference. After that, the fish tail end is continuously driven by the fish body conveyor belt 122, which in turn pushes the head end to continue moving on the wedge block 152. Finally, part of the head end extends out of the wedge block 152 and falls into the fish body receiving groove 131 under the action of gravity.

[0026] In this embodiment, the inclined baffle 151 forms an angle with the length direction of the fish conveyor belt 122, which is set to 15~20°. This angle generates sufficient lateral thrust to guide the fish to gradually adjust its orientation, while preventing the fish from tipping over or getting stuck due to excessive force caused by an excessively large angle, thus achieving stable posture correction. Furthermore, the length of the inclined baffle 151 can be set between 260~280mm. This length provides ample adjustment space for the fish, allowing it to slowly complete posture calibration along the inclined baffle 151 as it moves with the conveyor belt. This avoids insufficient posture adjustment due to a short travel distance, ensuring that the fish reaches the preset posture requirements when entering the next segment. It should be understood that the adjustment of the fish body's posture here can refer to gradually adjusting the fish body, which is placed horizontally on the fish body conveyor belt 122, to be placed vertically. Horizontal refers to the length direction perpendicular to the fish body conveyor belt 122, and vertical refers to the length direction of the fish body conveyor belt 122. Before the fish body enters the fish body receiving slot 131, the fish body can be placed completely vertically, or it can still have a certain angle with the vertical direction.

[0027] In some optional embodiments, the thickness of the wedge block 152 on the side near the fish body receiving groove 131 is greater than the thickness of the side of the wedge block 152 away from the fish body receiving groove 131, and the height of the top surface of the side of the wedge block 152 away from the fish body receiving groove 131 is lower than the height of the top surface of the fish body conveyor belt 122; it should be understood that the top surface here refers to the top surface of the wedge block 152 when the filefish processing device is placed on the floor of the work area, and the height of the top surface of the side of the wedge block 152 away from the fish body receiving groove 131 is lower than the height of the top surface of the fish body conveyor belt 122. The height of the top surface of the conveyor belt 122, that is, the thickness of the wedge block 152 on the side near the fish body conveyor belt 122, is less than the thickness of the wedge block 152 on the side near the fish body receiving groove 131. This makes the wedge block 152 form a natural transition slope. After the fish body is cut, it can slide smoothly up the wedge block 152 along this slope. During the conveyor belt transport process, the head end of the fish body will gradually exceed the edge of the wedge block 152, and finally fall accurately into the fish body receiving groove 131 under the action of gravity, realizing the smooth transition and directional reception of the fish body from the conveyor belt to the fish body receiving groove 131. Furthermore, since the fish's abdomen contains internal organs, which have a certain weight, the weight of the fish's belly is greater than the weight of its spine. During the process of falling from the wedge block 152 into the fish body receiving groove 131, the weight of the belly causes it to fall downwards before the spine, ensuring the fish enters the groove belly-down position, facilitating subsequent cutting and removal of the internal organs. Along the direction perpendicular to the length of the fish body conveyor belt 122, the width of the fish body receiving groove 131 near the wedge block 152 is greater than the width of the side away from the wedge block 152. In other words, the fish body receiving groove 131 adopts a gradually decreasing width design, with a wider inlet and a narrower outlet; the width is greater near the wedge block 152 and gradually narrows towards the outlet. The fish body receiving groove 131 has a wider inlet end, which can accurately match the trajectory of the fish body guided by the wedge block 152. Even if there is a slight deviation in the fish body posture, it can enter the groove smoothly, avoiding the fish body getting stuck or falling out of the conveying path due to the narrow inlet. The gradual structure from wide to narrow can gradually limit the fish body laterally during the movement of the fish body, slowly correct the fish body posture, and ensure that the fish body is output from the narrow end in a regular posture and smoothly enters the subsequent internal organ removal mechanism 2, laying the foundation for the precise operation of the next process.

[0028] In some optional embodiments, the viscera removal mechanism 2 includes a viscera support frame 21 and a fish body posture adjustment part 22 installed on the viscera support frame 21. The fish body posture adjustment part 22 communicates with the fish body receiving groove 131 and is used to extend the fish body along the interval direction between the fish head separation mechanism 1 and the viscera removal mechanism 2. In this embodiment, the fish body posture adjustment part 22 can further adjust the fish body posture. After the fish body posture is adjusted to a preset angle, it is more conducive to the subsequent viscera removal work.

[0029] See Figure 4 , Figure 8 and Figure 9 As shown, in some optional embodiments, the fish body posture adjustment part 22 may include a fish scale removal part 221, which includes: at least two rollers 2211, which are spaced apart along a length direction perpendicular to the second conveying part 12, and each roller 2211 is surrounded by a scraping layer 2212; a rotating shaft, which is connected to each roller 2211, and a drive gear 2213 is connected to each rotating shaft, with the drive gears 2213 connected to the two rollers 2211 meshing with each other; and a first driving member 2214, whose drive shaft is connected to one of the drive gears 2213. In this embodiment, two rollers 2211 are used, and the scaling layer 2212 can be a rubber layer. Preferably, the surface of the rubber layer can be evenly distributed with fine anti-slip bumps or shallow tooth-like textures, and the height of the bumps is controlled between 1-3mm. The distance between the two rollers 2211 is sufficient for the fish body to pass through. During the passage of the fish body, the two rollers 2211 rotate continuously under the drive of the first driving member 2214, scraping the fish scales through compression and rubber friction. The rotation of the two rollers 2211 also drives the fish body to move. In addition, the first driving member 2214 can be a servo motor. The drive gears 2213 connected to the two rollers 2211 mesh with each other. With the servo motor driving a single gear, the two rollers 2211 can be driven to rotate precisely and synchronously in opposite directions, ensuring that the force on both sides is balanced when the fish body passes through, and that no scales are missed or excessively compressed, thus improving the consistency of the scraping effect.

[0030] See Figure 10 and Figure 11As shown, in some optional embodiments, the viscera support frame 21 may include a bottom support frame 211 and a top support plate 212. The top support plate 212 and the bottom support frame 211 are spaced apart along a direction perpendicular to the plate surface of the first conveying part 32. The fish body posture adjustment part 22 further includes a height limiting part 222. The height limiting part 222 is located on the side of the fish scale removal part 221 away from the fish body receiving groove 131. The height limiting part 222 includes a fish belly support assembly. The fish belly support assembly includes a rotating rod 2221. The rotating rod 2221 is mounted on the bottom support frame 211, and the rotating rod 2221 is spaced perpendicular to the plate surface of the first conveying part 32. The second conveying section 12 extends along its length. The rotating rod 2221 is fixed with a fish belly support 2222, which has a support groove 2223. A spine limiting assembly is also included, comprising two telescopic rods 2224. One end of each telescopic rod 2224 is fixed to the side of the top support plate 212 near the bottom support frame 211. The two telescopic rods 2224 are spaced apart along the length direction perpendicular to the first conveying section 32. A spine limiting member 2225 is connected between the two telescopic rods 2224. The spine limiting member 2225 has a limiting groove 2226 that cooperates with the support groove 2223. Specifically, after passing through the scale removal section 221, the fish body is positioned vertically by the action of the double rollers 2211. The fish body is then conveyed to the height limiting section 222, which precisely adjusts the position of the fish body in the width direction of the viscera support frame 21, ensuring a uniform and centered posture. It should be understood that the fish belly support 2222 may include two truncated cones, both fixed to the rotating rod 2221 and symmetrically distributed along the length of the rotating rod 2221. The small end faces of the two cones are close to and abut against each other, while the large end faces face opposite directions. Together, they form a support groove 2223 that is concave in the middle and gradually expands outwards at both ends, adapting to the arc-shaped contour of the fish belly to stably support the fish body. In this embodiment, the rotating rod 2221 can also be driven by a servo motor. Furthermore, the limiting groove 2226 of the spine limiting member 2225 can cooperate with the support groove 2223 to make the fish body be in a belly-down position. By connecting the spine limiting member 2225 to the telescopic rod 2224, the telescopic length of the two telescopic rods 2224 can be adjusted synchronously according to the size of the filefish to be processed, so that the spine limiting member 2225 can move up and down, so that the limiting groove 2226 and the support groove 2223 of the belly support member 2222 form a clamping space that is adapted to the height of the fish body, and ensure that the spine of the fish body is fitted and limited by the limiting groove 2226 as much as possible.Preferably, the telescopic rods 2224 can be telescopically extended using a hydraulic telescopic structure in related technologies. Each telescopic rod 2224 is fitted with a spring 2227, one end of which is fixed to the top support plate 212. A rotating rod is rotatably connected between two telescopic rods 2224. The spine limiting member 2225 is fixed to the rotating rod. The rotating rod can also be driven by another servo motor. The spine limiting member 2225 and the fish belly support member 2222 can both be provided with ribs on their outer periphery so that the spine limiting member 2225 and the fish belly support member 2222 can cooperate to limit the movement of the fish body while also driving the fish body to move.

[0031] In some optional embodiments, the viscera removal mechanism 2 further includes a limiting cutting section 23, which includes: at least two sets of limiting drive components 29, which are installed on the side of the height limiting section 222 away from the fish scale removal section 221, and the at least two sets of limiting drive components 29 are spaced apart along the length direction perpendicular to the second conveying section 12, forming a fish body passage channel between the at least two sets of limiting drive components 29, and the limiting drive components 29 are used to drive the fish body to move along the length direction of the second conveying section 12; a guide plate 232, which is installed in the fish body passage channel, and the height of the guide plate 232 near the height limiting section 222 is lower than the height of the guide plate 232 away from the height limiting section 222, a fish belly cutting piece 233 is installed on the side of the guide plate 232 away from the height limiting section 222, and an organ dropping hole is opened on the side of the guide plate 232 near the fish belly cutting piece 233. See Figure 16As shown, the fish belly cutting component 233 can be set in a shape similar to an axe. The wedge-shaped head of the axe-shaped fish belly cutting component 233 can be inserted into the opening of the fish belly to form a stable guide, ensuring that the cutting component moves along the center line of the fish belly, reducing the situation where the cutting deviates from the trajectory due to slight shaking of the fish body, and improving the accuracy of the cutting position. In this embodiment, each set of limiting drive components 29 may include three push cylinders. The axis of each push cylinder is perpendicular to the surface direction of the top support plate 212, and each of the three push cylinders is fixed with a connecting rod. The connecting rod is coaxially arranged with the push cylinder and is rotatably mounted between the top support plate 212 and the bottom support frame 211. The three connecting rods are driven synchronously, so that the two sets of limiting components can clamp the fish body while also driving the fish body to move. The synchronous driving of the three connecting rods can be achieved by fixing gears at the ends of the three connecting rods in each set, and the gears fixed on adjacent connecting rods meshing with each other. The two connecting rods in the two sets of limiting drive components 29 that are spaced perpendicular to the passage through the fish body can also be driven by meshing gears at their ends. That is, only one end of one connecting rod needs to be connected to a motor. When the motor drives one connecting rod to rotate, the other connecting rods in the limiting drive component 29 are also driven synchronously. Furthermore, as the motor drives the gear to rotate, the upper connecting rod rotates simultaneously, and the push cylinder fixed on the connecting rod also rotates synchronously, with a rotation angle of approximately 25°–75°. Preferably, see [reference needed]. Figure 17 As shown, a bottom support plate 26 is installed on the top surface of the bottom support frame 211. Both the bottom support plate 26 and the top support plate 212 can have multiple arc-shaped grooves and through holes that cooperate with the connecting rods. The arc-shaped grooves and through holes on the bottom support plate 26 and the top support plate 212 are symmetrically arranged along the connecting rods. That is, the ends of some connecting rods pass through the arc-shaped grooves on the bottom support plate 26 and the top support plate 212, while the ends of others pass through the through holes on the bottom support plate 26 and the top support plate 212. An adaptive system with a spring structure can be connected between two connecting rods arranged perpendicular to the fish body passageway in the two sets of limiting drive assemblies 29 to limit the movement and position recovery of the adaptive system. Through this structure, the distance of the fish body passageway along the width direction of the visceral support frame 21 can be adjusted to accommodate various fish bodies of different sizes.

[0032] Furthermore, when the head of the fish passes through the height limiting part 222 and the tail is still within the height limiting part 222, the head then enters the fish body passage channel. Under the action of the pushing cylinder, the fish body is continuously pushed into the guide plate 232. As the guide plate 232 gradually increases in height from the side near the height limiting part 222 to the side away from the height limiting part 222, the fish body is gradually lifted until it moves to the abdominal cutting piece 233, where the abdomen is gradually cut open, exposing the viscera. The abdominal cutting piece 233 can also be a cutting blade. Preferably, a flushing pipe 27 is installed on the bottom support frame 211 near the abdominal cutting piece 233. After the fish's abdomen is cut open and the viscera are exposed to the external environment, water flows out of the flushing pipe 27 to rinse the fish's abdomen, washing away the viscera and causing them to fall out of the guide plate 232 through the viscera drop hole. A flushing pipe 27 is installed next to the fish belly cutting piece 233 on the bottom support frame 211. After the fish belly is cut open, the flushing pipe 27 sprays water to rinse the inside of the fish belly, completely flushing the internal organs away from the fish body. The internal organs fall through the organ drop hole into the inclined drop plate 28, and then slide along the drop plate 28 into the detachable internal organ collection frame 25 below the bottom support frame 211, realizing centralized collection of internal organs. In this embodiment, the height of the guide plate 232 gradually increases in conjunction with the push of the pusher cylinder, allowing the fish body to be lifted more smoothly and accurately aligned with the cutting piece, avoiding positional displacement during the belly cutting.

[0033] See Figure 12 and Figure 15 As shown, in some optional embodiments, a sliding plate 24 is also connected to the side of the guide plate 232 away from the height limiting part 222. The height of the side of the sliding plate 24 near the height limiting part 222 is higher than the height of the side of the sliding plate 24 away from the height limiting part 222. The end of the sliding plate 24 away from the guide plate 232 is connected to the first conveying part 32. The flesh-separating mechanism 3 also includes a back cutting member 35, which is installed on the end of the first conveying part 32 near the sliding plate 24. In this embodiment, the sliding plate 24 gradually lowers its height, and the fish body slides on the sliding plate 24 to the first conveying part 32 through the height difference. After the abdomen of the fish body passes the belly cutting member 233, the abdomen is completely separated. When the fish body reaches the sliding plate 24, the entire fish body is in a position of lying flat on the sliding plate 24. The spine-cutting component 35 can be a spine knife, which is mounted on one end of the first conveying unit 32 near the sliding plate 24 via a rotating shaft. When the fish body, which is laid flat on the sliding plate 24, passes the spine-cutting component 35, the spine of the fish body is cut open, and the entire fish body is divided into two parts. The fish body, which has been cut into two parts, enters the tilting roller 34 under the conveying of the first conveying unit 32 until it is cut by the fish skin cutting part 33, thus completing the processing of the fish.

[0034] This application also provides a method of using a filefish processing device, which is applied to the filefish processing device described above. The method of use may include: S1: Place the filefish in the second conveyor section 12, and use the cutting piece 14 to separate the filefish's head and body. The head and body are separated by openings, and the head can fall into the head collection box 16 through the head drop hole 132, while the body continues to be driven into the next processing step.

[0035] S2: The fish body is driven from the fish body receiving groove 131 into the viscera removal mechanism 2, and the abdomen of the fish body is cut open using the fish belly cutting piece 233. After the fish head is separated, the fish body is accurately delivered into the fish body receiving groove 131 by the continuous conveying of the fish body conveyor belt 122, and then smoothly enters the viscera removal mechanism 2 under the combined action of pushing force and its own gravity. After passing through the fish scale removal section 221, the fish body is then calibrated and fixed in position by the height limiting section 222, and then continuously pushed by the pusher to the guide plate 232. The guide plate 232 gradually rises in height along the conveying direction, causing the fish body to gradually lift up and accurately align with the fish belly cutting piece 233. As the fish body moves smoothly with the guide plate 232, the fish belly cutting piece 233 gradually cuts open the abdomen along the midline of the fish belly, completely exposing the internal organs, laying the foundation for subsequent viscera rinsing and cleaning and subsequent processing steps.

[0036] S3: Use the back cutting tool 35 to cut the connection point of the fish's spine. Before using the back cutting tool 35 to cut the connection point of the fish's spine, the internal organs were removed.

[0037] S4: The fish body is driven through the tilting roller 34. When the tilting roller 34 cooperates with the first conveyor 32 to squeeze the fish body, the fish skin cutting part 33 separates the fish skin and fish meat. The tilting roller 34 and the conveyor belt of the first conveyor 32 form a squeezing gap adapted to the thickness of the fish body. Driven by the drive motor, the tilting roller 34 can rotate synchronously with the speed matching the conveyor belt's conveying rhythm. With the help of the friction between the roller and the surface of the fish body, the fish body is smoothly driven through the squeezing gap at a uniform speed. When the fish body is in the state of being squeezed by the tilting roller 34 and the conveyor belt, the fish skin cutting part 33 smoothly separates the fish skin and fish meat along the fish body conveying direction, achieving the initial separation of the two. During the cutting process, due to the stable squeezing of the tilting roller 34, the fish body posture is kept as regular as possible, laying a solid foundation for the subsequent complete separation of skin and meat.

[0038] In this embodiment, the filefish processing device is suitable for filefish with a body length of 18-28cm and a weight of 200-400g, and is adapted to their laterally compressed, elongated oval shape, small mouth, and long snout. Before using the filefish processing device, the device can be adjusted and the accuracy of the measuring tools can be calibrated.
