Description

Technical Field

[0001] This invention relates to an adaptive integrated machine for slaughtering, slicing, and packaging fish. Background Technology

[0002] The initial processing of fish mainly includes descaling, eviscerating, head removal, deboning, and slicing. Traditional methods primarily involve manual hand-held knives for gutting, eviscerating, and cutting, supplemented by simple descaling brushes or benchtop descaling machines. This method has significant drawbacks: firstly, it is inefficient and cannot meet the demands of large-scale production; secondly, the working environment is slippery, cold, and has a fishy smell, leading to a serious loss of labor and exacerbating the problems of "difficulty in recruiting and high labor costs"; and thirdly, product quality is highly dependent on the operator's experience and feel, resulting in incomplete descaling, a high rate of fish damage, and the traditional method of gutting easily punctures the gallbladder, causing bile contamination of the fish meat and resulting in bitterness, leading to economic losses from the disposal of the entire fish. Existing fish processing equipment is mostly single-function specialized machines, such as handheld electric descaling machines and simple gutting machines. These devices can only complete a single process and cannot achieve continuous operation from descaling to packaging. They also lack adaptability to the size and shape of the raw fish, still requiring manual assistance for positioning and feeding, and have a low level of automation. Summary of the Invention

[0003] The present invention provides an adaptive fish slaughtering, slicing and packaging integrated machine to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this invention are as follows:

[0005] An adaptive fish slaughtering, slicing and packaging integrated machine, including

[0006] frame;

[0007] The conveying device is mounted on the frame and is used to carry the fish through different processing stations on the frame in sequence;

[0008] The equipment includes descaling devices, cleaning devices, evisceration devices, head removal devices, deboning devices, and slicing devices installed at corresponding processing stations; among them...

[0009] The visceration device includes a visceration shaft that can be inserted into the fish belly and rotate around its own axis to wrap around the viscera; a cleaning device is arranged above the visceration shaft to rinse the wrapped visceration shaft; a head removal device is arranged downstream of the visceration device to remove the fish head; a deboning device is arranged downstream of the head removal device to remove the central bone; and a slicing device is arranged downstream of the deboning device to slice the fish meat.

[0010] Furthermore, the viscera removal device is provided with barbs in the circumferential direction for wrapping around the viscera.

[0011] Furthermore, the viscera removal device also includes a mounting plate, a servo motor, a rocker arm, a coupling, and a turntable. The mounting plate is mounted on the frame and can move up and down. The turntable is rotatably mounted on the mounting plate. The viscera removal shaft is mounted on the turntable via the coupling. The servo motor is mounted on the turntable. The rocker arm is mounted on the output end of the servo motor, and the rocker arm is connected to the free end of the outer side of the coupling. The servo motor drives the rocker arm to swing, thereby causing the viscera removal shaft to swing in the horizontal plane.

[0012] Furthermore, the frame is equipped with two parallel electric lead screws, one of which has its lifting free end connected to the mounting plate and used to drive the internal organ device to lift, and the other electric lead screw has a tail cutting blade fixed to its lifting free end.

[0013] Furthermore, the conveying device includes an optical shaft, a power roller, a sprocket, a spiked chain, and multiple scale-scraping wheels. Several optical shafts are mounted on the frame, and the power roller and scale-scraping wheels are rotatably sleeved on the optical shafts, with the axes of the power roller and scale-scraping wheels perpendicular to each other. The sprocket is connected to the frame, and two spiked chains are arranged in parallel and wound around the corresponding sprockets. There are an even number of power rollers divided into two groups, and gaps for conveying fish are provided between the two groups of power rollers and between the two sprockets.

[0014] Furthermore, the descaling device includes two scraping rollers arranged at intervals to form a gap for conveying the fish body.

[0015] Furthermore, the cleaning device includes a water tank, a water pump, and a water outlet pipe. The water tank is located at the bottom of the frame, and the water pump connects the water tank and the water outlet pipe to achieve water circulation rinsing.

[0016] Furthermore, the head removal device includes an electric push rod fixing plate, an electric push rod, and a head cutter. The electric push rod fixing plate is fixed to the frame, the electric push rod is horizontally installed on the electric push rod fixing plate, and the head cutter is fixed to the telescopic end of the electric push rod and is opposite to the cutting position of the fish head.

[0017] Furthermore, the deboning device includes a transmission belt, a handwheel, a deboning blade, and a timing belt. The transmission belt and timing belt are both mounted on the frame and work together to transport the headless fish. The deboning blade is positioned at the midbone position in the fish transport path. The handwheel is rotatably connected to the frame and to the deboning blade, and is used to adjust the spacing of the deboning blade.

[0018] Furthermore, the bone removal device also includes a support roller fixing frame and a support roller, wherein the support roller is rotatably mounted on the support roller fixing frame and abuts against the outside of the timing belt.

[0019] Furthermore, the slicing device includes a pressure plate, a blade assembly, and a crank-connecting rod mechanism. The pressure plate is elliptical and mounted on the frame and is opposite to the fish meat pressing position. The blade assembly is slidably mounted on the frame, and the crank-connecting rod mechanism drives the blade assembly to perform reciprocating linear cutting motion.

[0020] This adaptive fish slaughtering, slicing, and packaging integrated machine, through its integrated and automated structural design and innovative visceration process, achieves mechanized operation throughout the entire fish processing workflow. It effectively solves industry pain points in traditional fish primary processing, such as high reliance on manual labor, low processing efficiency, poor product standardization, and significant raw material loss. The beneficial effects of this invention are as follows:

[0021] (1) The innovative process of removing internal organs without evisceration fundamentally avoids the problem of the traditional evisceration method easily puncturing the gallbladder and causing the fish meat to be scrapped. The internal organs are completely removed by rotating and winding the barbed evisceration shaft. With the help of the servo motor to precisely adjust the angle of the evisceration shaft, the thoroughness of evisceration can be guaranteed, and damage to the abdominal cavity wall of the fish can be avoided. This greatly reduces the raw material loss during processing, improves the product qualification rate, and reduces economic losses.

[0022] (2) The entire process of fish processing, from feeding and conveying, scaling, cleaning, eviscerating, removing the head and bones to slicing, is fully automated and continuous. Each processing device is precisely linked through transmission structures such as motors, stepper motors, chains and sprockets. No manual intervention is required during the operation, which effectively solves the problem of "difficulty in recruiting workers and high labor costs" in the aquatic product processing field, greatly reduces the labor intensity of operators, and significantly improves the overall processing efficiency compared with traditional manual or semi-automatic processing methods, meeting the needs of large-scale and industrialized production.

[0023] (3) The equipment has good versatility and adaptability. The conveying device achieves elastic sliding of the movable scraping wheel through the cooperation of spring and linear bearing, which can fit the fish of different shapes and sizes to complete the conveying and initial scraping. The servo motor can flexibly adjust the insertion angle of the viscera removal shaft to adapt to the abdominal cavity structure of different fish species. The spacing of the deboning blades can be easily adjusted through the handwheel to meet the deboning needs of fish of different thicknesses. It breaks the limitation of traditional fish processing equipment that can only adapt to a single fish species. It can be used for the processing of a variety of common freshwater and saltwater fish such as sea bass and carp, with a wide range of applications, which enhances the utilization value of the equipment.

[0024] (4) The structural design of each processing device ensures the standardization and precision of fish processing. The electric push rod horizontally drives the head cutter to quickly and accurately remove the fish head, resulting in a clean cut. The slicing device uses a stepper motor to drive the pressure plate to press the fish meat, and in conjunction with the crank-connecting rod mechanism, it drives the blade to perform reciprocating linear cutting motion, which can cut the fish meat into slices of uniform thickness and size. The deboning device uses a support roller to support the synchronous belt, ensuring the levelness of the fish transport and allowing the deboning blade to accurately align with the central bone, achieving efficient removal of the central bone. The precise control of the overall processing process means that the quality of fish processing no longer depends on the experience of the operators, greatly improving the standardization of the products. This can provide catering establishments and aquatic product processing enterprises with uniformly high-quality primary processed fish products, which is conducive to the branding development of the industry.

[0025] (5) The cleaning device adopts a water circulation design with water tank, water pump and water outlet pipe. The cleaning water can be recycled and there is no need to continuously add new water, which effectively saves water resources and reduces the production cost of fish processing. At the same time, the cleaning device is set directly in front of the visceration shaft and the fish body processing position. After the visceration operation is completed, the visceration shaft and the fish body can be rinsed simultaneously. This ensures the cleanliness of the visceration shaft and avoids the residue of impurities affecting subsequent processing. It can also remove blood and impurities from the surface of the fish body and improve the hygiene quality of the processed fish.

[0026] (6) The equipment adopts an integrated design. All functional devices are reasonably arranged and integrated on the same frame. The overall layout is compact, occupies little production space, and is easy to arrange and install in the aquatic product processing production line. The components of each device are fixed and connected by standardized accessories such as bearing seats, flanges, and motor seats. The transmission structure is simple and the linkage is smooth. The equipment has strong operating stability. Subsequent inspection, maintenance and parts replacement are convenient, reducing the operation and maintenance cost of the equipment.

[0027] (7) The operation of each processing link of the equipment is smooth and seamless. From the fish body feeding to the finished product output, a closed-loop operation is formed. There is no intermediate manual transfer link, which reduces the contact contamination of fish products during processing and improves the hygiene and safety of the products. At the same time, the automated processing method reduces the contact between human and wet processing environment, improves the working environment of operators, and reduces the safety hazards of manual operation.

[0036] The invention will now be further described with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the present invention discloses an adaptive fish slaughtering, slicing, and packaging integrated machine, comprising a conveying device 1, a descaling device 2, a cleaning device 3, a viscera removal device 4, a head removal device 5, a deboning device 6, a slicing device 7, and a frame 9. The frame 9 serves as the overall load-bearing foundation, and all functional devices are integrated and installed at preset workstations on the frame 9. The conveying device 1 is arranged linearly along the length of the frame 9 and serves as the core conveying mechanism for the fish, driving the fish from the feeding end to the corresponding processing positions of the descaling device 2, cleaning device 3, viscera removal device 4, head removal device 5, deboning device 6, and slicing device 7 in sequence, realizing fully automated processing of the fish from fresh fish feeding to finished sliced ​​fish meat. The structural coordination, installation method, and specific operation details of each device are as follows.

[0038] like Figure 2 The conveying device 1 on the frame 9 provides power to the fish throughout the process and also completes the initial scaling action. The conveying device 1 is equipped with several optical shafts 10, several power rollers 15, two spiked chains 27 and multiple scaling wheels 21. The optical shafts 10 are fixedly installed vertically and horizontally at various preset installation points on the frame 9 through optical shaft fixing seats 901 to ensure the installation stability of the optical shafts 10. The power rollers 15 and scaling wheels 21 are rotatably mounted on the optical shafts 10 through bearings and can rotate freely around the optical shafts 10.

[0039] Multiple sprockets are also installed on the frame 9 at positions corresponding to the spiked chain 27. The spiked chain 27 is wound around and connected to the sprockets for transmission. The conveying surfaces of the spiked chain 27 create a conveying space. After the fish enters from the feed end, it is conveyed sequentially by the power roller 15 and the spiked chain 27. The motor drives the sprockets to rotate through the chain 16, and the power roller 15 uses friction to drive the fish to move smoothly along the frame 9 to the subsequent processing station.

[0040] The conveying device 1 is also equipped with a linear bearing 13 and a spring 14. The linear bearing 13 is slidably sleeved on the optical axis 10 and can slide freely along the optical axis 10. The spring 14 is sleeved on the optical axis 10, with one end abutting against the end face of the linear bearing 13 and the other end abutting against the optical axis fixing seat 901 of the frame 9.

[0041] The scaler 21 is divided into a fixed scaler and a movable scaler. The fixed scaler is directly fixed to the optical shaft 10, while the movable scaler is fixedly connected to the linear bearing 13 (a mounting block is set on the linear bearing, and the movable scaler rotates on the mounting block). When fish of different sizes and shapes pass the position of the scaler 21, the side of the fish will push the movable scaler, causing the linear bearing 13 to slide along the optical shaft 10. At the same time, the spring 14 is compressed. The elastic restoring force of the spring 14 is used to keep the movable scaler in close contact with the surface of the fish. This ensures the stability of different fish during transportation and allows the scaler 21 to fully contact the surface of the fish, achieving preliminary scaling of the fish and effectively improving the comprehensiveness of scaling.

[0042] like Figure 3 The descaling device 2 is installed beside the fish conveying path of the conveying device 1 and is connected to the position of the scraping wheel 21 to complete the precise and deep descaling of the fish. The descaling device 2 is equipped with a scraping roller 33, a thrust ring 32, and a scraping device guard plate 34. The scraping device guard plate 34 is fixedly sleeved on the optical shaft 10 by a flange. The scraping roller 33 is evenly installed on the optical shaft 10 through the scraping device guard plate 34, and the working surface of the scraping roller 33 faces the fish conveying path and forms a suitable contact angle with the surface of the fish. The motor on the frame 9 drives the optical shaft 10 to rotate through the chain and sprocket. The optical shaft 10 rotates in tandem with the fish. The step drives the scraping roller 33 to rotate. When the fish passes through the scraping roller 33 under the drive of the conveying device 1, the rotating scraping roller 33 makes full contact with the surface of the fish, achieving precise and deep descaling of the fish and completely removing the scales from the surface of the fish. The thrust ring 32 is also sleeved on the optical shaft 10 and abuts against the two end faces of the scraping device guard plate 34, forming a precise limit on the axial position of the scraping device guard plate 34, preventing axial displacement of the scraping device guard plate 34 and the scraping roller 33 during high-speed rotation, ensuring the precise contact position between the scraping roller 33 and the fish, and ensuring the stability of the descaling effect.

[0043] like Figure 4 The cleaning device 3 is positioned above the visceration device 4 and opposite the fish transport path to complete the synchronous cleaning of the visceration shaft 46 and the fish. The cleaning device 3 is equipped with a water tank 36, a water pump 37, and a water outlet pipe 38. The water tank 36 is installed at the bottom of the frame 9 to store cleaning water. The water outlet pipe 38 is fixedly installed on the frame 9 above the visceration device 4 via a bracket, with the water outlet facing the visceration shaft 46 and the processing position of the fish. The water pump 37 is fixedly installed on the frame 9, and the water inlet of the water pump 37 is connected to the water tank 36 via a pipe, and the water outlet is connected to the water outlet pipe 38 via a pipe, forming a complete water circulation cleaning structure.

[0044] After the evisceration device 4 completes the process of wrapping the fish's internal organs, the water pump 37 starts, drawing clean water from the water tank 36 and spraying it out at high pressure through the outlet end of the water pipe 38. This directly washes the evisceration shaft 46, which is wrapped with internal organs, and thoroughly washes off the internal organs and residual impurities wrapped on the evisceration shaft 46. At the same time, the sprayed clean water also rinses the surface of the fish after the evisceration process, cleaning off the impurities and blood on the surface of the fish. The wastewater after rinsing flows back to the water tank 36 at the bottom through the guide structure of the frame 9, realizing the recycling of cleaning water, effectively saving water resources and reducing processing costs.

[0045] like Figure 5 , Figure 6 and Figure 7 The visceration device 4 is located below the cleaning device 3 and downstream of the descaling device 2, enabling visceration of the fish without gutting it. In addition to a visceration shaft 46 that can be inserted into the fish's belly and rotate around its own axis to wrap around the viscera, the visceration device 4 is also equipped with a mounting plate 41, a servo motor 42, a rocker arm 45, a coupling 47, a turntable 48, a bevel gear 49, a stepper motor, and a tail-cutting blade 52. The circumferential surface of the visceration shaft 46 is evenly provided with barbs, which can greatly improve the wrapping and gripping effect on the fish's viscera, prevent the viscera from falling off during the wrapping process, and ensure the integrity of the visceration operation.

[0046] Mounting plate 41 is connected to the optical axis 10 of frame 9 via linear bearing, allowing for smooth lifting and lowering along the optical axis 10. The main shaft of the viscera removal device is rotatably mounted on mounting plate 41 via a diamond bearing seat and bearing, allowing free rotation around its own axis. Turntable 48 is fixedly mounted on the end of the main shaft of the viscera removal device via a flange, rotating synchronously with the main shaft. The viscera removal shaft 46 is mounted on the end face of turntable 48 via coupling 47, moving together with turntable 48. Servo motor 42 is fixedly mounted on turntable 48 via servo motor mounting bracket 43. One end of rocker arm 45 is fixedly mounted on the output end of servo motor 42, and the other end is movably connected to the free end of the outer side of coupling 47. Stepper motor is fixedly mounted on mounting plate 41 via stepper motor seat, and a bevel gear 49 is fixedly mounted on its output end. This bevel gear 49 meshes with the bevel gear 49 fixedly mounted on the main shaft of the viscera removal device, forming a bevel gear transmission structure.

[0047] Two electric lead screws are also arranged in parallel on the frame 9. The free end of the lifting of one of the electric lead screws is fixedly connected to the bottom of the mounting plate 41, which can drive the mounting plate 41 to move up and down, thereby driving the entire internal organ removal shaft 46 and other components to achieve height adjustment, adapting to the processing needs of fish with different body lengths and different abdominal cavity heights. The free end of the lifting of the other electric lead screw is fixedly installed with a tail cutting blade 52. The blade of the tail cutting blade 52 faces upward, corresponding to the cutting position of the tail of the fish.

[0048] The specific working process of the viscera removal device 4 is as follows:

[0049] When the fish reaches the processing station of the evisceration device 4 under the drive of the conveyor 1, the electric screw that drives the tail-cutting blade 52 is activated, driving the tail-cutting blade 52 to move upward and quickly cut off the tail of the fish, providing a smooth entry point for the evisceration shaft 46 to be inserted into the fish's abdomen. Subsequently, the electric screw that drives the mounting plate 41 is activated, driving the mounting plate 41 to move downward to a preset height, so that the evisceration shaft 46 is at the same level as the abdominal cavity entrance of the fish. At this time, the servo motor 42 is activated, driving the rocker arm 45 to swing around the output end of the servo motor 42. During the swinging process, the rocker arm 45 drives the coupling 47 to rotate around its own axis, thereby driving the evisceration shaft 46 to swing and adjust in the horizontal plane. The insertion angle of the visceration shaft 46 is precisely adjusted to match the abdominal cavity entrance of the fish, avoiding damage to the abdominal cavity wall during insertion. After the angle adjustment is completed, the conveying device 1 continues to move the fish forward, slowly inserting the visceration shaft 46 into the fish's abdomen. Once the visceration shaft 46 is inserted to the preset depth, the stepper motor starts, driving the bevel gear 49 at its output end to rotate. Through the meshing transmission of the bevel gear, the main shaft of the visceration device rotates around its own axis. The main shaft of the visceration device synchronously drives the turntable 48 and the visceration shaft 46 to rotate around their own axis. The barbs around the visceration shaft 46 quickly wrap the fish's internal organs around the shaft of the visceration shaft 46.

[0050] After the internal organs are wrapped and grasped, the conveyor 1 moves the fish body backward slowly, smoothly pulling the viscera removal shaft 46 with the internal organs wrapped around it out of the fish's belly. At this time, the water pump 37 of the cleaning device 3 starts simultaneously, spraying clean water through the water outlet pipe 38 to perform high-pressure rinsing on the viscera removal shaft 46, completely washing off the internal organs wrapped around the shaft, completing the viscera removal operation of the fish body. Afterward, the two electric lead screws start respectively, driving the mounting plate 41 and the tail cutting blade 52 to return to the initial position, waiting for the processing of the next fish body.

[0051] like Figure 8The head-removing device 5 is located downstream of the visceration device 4, corresponding to the head-cutting position of the fish, to complete the automated head-removing operation. This head-removing device 5 is equipped with an electric push rod fixing plate 53, an electric push rod 54, and a head-cutting blade 55. The electric push rod fixing plate 53 is bolted to the two side frames of the machine frame 9 to ensure a secure installation. The electric push rod 54 is horizontally mounted on the electric push rod fixing plate 53, with its telescopic end facing the fish's conveying path. The head-cutting blade 55 is bolted to the telescopic end of the electric push rod 54, with the blade of the head-cutting blade 55 aligned with the head of the fish. The cutting position is precisely matched. When the fish body that has completed the internal organ removal operation arrives at the processing position of the head removal device 5 under the drive of the conveyor device 1 and is in the preset cutting position, the electric push rod 54 is activated. Its telescopic end extends horizontally forward, driving the head cutter 55 to move quickly towards the head of the fish body. The head of the fish body is quickly removed by the blade of the head cutter 55. After the head is removed, the telescopic end of the electric push rod 54 immediately retracts horizontally, driving the head cutter 55 to return to the initial position, waiting for the head removal processing of the next fish body. The entire head removal process is fast and precise, effectively ensuring the efficiency of head removal and the flatness of the cut.

[0052] like Figures 9 to 11 The deboning device 6 is located downstream of the head-removing device 5 and completes the deboning of the fish body after head removal. The deboning device 6 is equipped with a transmission belt 56, a timing belt 62, a deboning blade 60, a handwheel 59, a support roller fixing frame 57, a support roller 58, and a lead screw.

[0053] The transmission belt 56 is mounted on the frame 9 via a power roller and an optical shaft, smoothly conveying the headless fish to the deboning processing position. The synchronous belt 62 is mounted on the frame 9 via a synchronous pulley 61. The two rows of synchronous belts 62 are arranged in parallel to form a fish clamping and conveying structure, clamping the fish and conveying it forward smoothly. The deboning blade 60 is mounted on the output end of the motor via a flange. The motor drives the deboning blade 60 to rotate. The deboning blade 60 is set at the corresponding position of the central bone in the fish conveying path, accurately aligning with the central bone position of the fish. A lead screw is also rotatably mounted on the frame 9 via a vertical bearing seat. One end of the lead screw is fixedly mounted with a handwheel 59, and the other end is connected to the motor on which the deboning blade 60 is mounted. The operator can manually rotate the handwheel 59 to drive the lead screw to rotate according to the thickness of the fish and the width of the central bone, thereby adjusting the spacing between the deboning blades 60 to adapt to the deboning of fish of different sizes and ensure the deboning effect.

[0054] The support roller fixing frame 57 is connected to the optical axis of the frame 9 via a linear bearing and can slide slightly along the optical axis. The support roller 58 is rotatably mounted on the support roller fixing frame 57 via the bearing, and the top surface of the support roller 58 abuts against the outer side of the bottom surface of the synchronous belt 62, forming an upward supporting force on the synchronous belt 62. This prevents the synchronous belt 62 from sinking excessively when carrying the fish, ensuring that the fish remains horizontal during transport. This allows the deboning blade 60 to accurately align with the midbone of the fish. When the fish passes through the high-speed rotating deboning blade 60 while being held and driven by the synchronous belt 62, the midbone is quickly and accurately removed, achieving separation of the fish from the midbone and completing the deboning operation.

[0055] like Figure 12 The slicing device 7 is located downstream of the deboning device 6 and is the final step in fish processing, completing the standardized slicing of the deboned fish meat. The slicing device 7 includes a pressure plate 63, a slicing device frame 64, a blade rack 66, a connecting rod 67, a crank 68, a stepper motor, a lead screw, and a slide rail. The slicing device frame 64 is bolted to the machine frame 9, providing a mounting base for all components of the slicing device 7. The pressure plate 63 is connected to the slicing device frame 64 via the slide rail, allowing for smooth lifting and lowering along the slide rail. The pressure plate 63 is positioned directly above the fish meat processing area. The blade rack 66 is also slidably mounted below the slicing device frame 64 via a slide rail slider, allowing it to reciprocate linearly along the slide rail slider. Multiple cutting blades are evenly mounted on the blade rack 66, enabling simultaneous multi-blade cutting of the fish meat. A motor is mounted on the frame 9, with one end of the crank 68 fixedly mounted at the motor's output end and the other end hinged to one end of the connecting rod 67. The other end of the connecting rod 67 is hinged to the end of the blade rack 66, forming a crank-connecting rod transmission structure.

[0056] The stepper motor is fixedly mounted on the frame 9 via a stepper motor mount. The lead screw is connected to the output end of the stepper motor via a bearing. The pressure plate 63 is connected to the lead screw via a nut. The stepper motor can drive the pressure plate 63 to move up and down via the lead screw. When the deboned fish meat arrives at the processing station of the slicing device 7 under the drive of the conveyor belt 56 and falls into the preset cutting position, the stepper motor starts and drives the lead screw to rotate around its own axis. Through the transmission action of the nut, the pressure plate 63 moves smoothly downward along the slide rail slider, pressing the fish meat tightly on the processing table to prevent the fish meat from slipping or shifting during the slicing process and to ensure the accuracy of the slicing. After the pressure plate 63 presses the fish meat, the motor starts and drives the crank 68 to rotate around the output end of the motor. During the rotation of the crank 68, the connecting rod 67 drives the blade plate 66 to move in a high-speed reciprocating linear motion along the slide rail slider. The cutting blades on the blade plate 66 continuously cut the pressed fish meat into fish slices of uniform size and thickness. After the slicing operation is completed, the stepper motor starts in reverse and drives the lead screw to rotate in reverse, driving the pressure plate 63 to return to its original position along the slide rail slider. The cut fish slices leave the slicing station with the conveyor belt 56, completing the entire automated processing process of the fish.

[0057] The entire adaptive fish slaughtering, slicing, and packaging integrated machine achieves power linkage between its various components through transmission structures such as motors, stepper motors, chains 16, and sprockets. The actions of each processing station are precisely and smoothly connected, requiring no manual intervention. It realizes fully automated operation of the entire process of fish conveying, descaling, cleaning, devising, head removal, deboning, and slicing. At the same time, through various structural designs such as the elastic adaptation of spring 14, the angle adjustment of servo motor 42, and the spacing adjustment of handwheel 59, the equipment can adapt to the processing needs of fish of different sizes, shapes, and varieties, effectively improving the efficiency and standardization of fish processing, significantly reducing the intensity of manual labor, and solving the problems of low efficiency, poor standardization, easy damage to fish, and easy breakage of gallbladder in traditional fish processing, thus meeting the needs of large-scale, industrialized fish processing production.

[0058] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
