Description

Technical Field

[0001] This invention relates to the field of fish pretreatment technology, specifically to an intelligent fish pretreatment machine. Background Technology

[0002] Fish is a highly nutritious food, rich in high-quality, easily digestible animal protein, unsaturated fatty acids, and various essential nutrients such as calcium, phosphorus, and vitamin D. It is also low in fat. Long-term consumption can help meet the nutritional needs of human growth, development, and tissue repair, which aligns with the modern trend of healthy eating. In home cooking or catering processing, fish processing machines are usually needed to process fish by scaling, gutting, and removing internal organs.

[0003] In the prior art, Chinese patent CN221410249U discloses an automatic fish-killing machine. Below the first conveyor belt is a downwardly inclined material drop seat. At least two feeding screws are installed inside the material drop seat. The distance between the feeding screws and the bottom surface of the material drop seat gradually decreases along the inclined direction. A material drop hopper is located on the side of the material drop seat away from the first conveyor belt. The discharge end of the material drop hopper is sequentially connected to a first conveying mechanism, a descaling mechanism, and a fish-cleaning mechanism. The descaling mechanism and the fish-cleaning mechanism are each equipped with a second conveying mechanism. First, a batch of fish is placed on the first conveyor belt. After being conveyed by the first conveyor belt, the fish fall to the upper end of the material drop seat. As the fish slides down, it is conveyed by the feeding screws to the material drop hopper. Then, it is conveyed by the first conveying mechanism through the descaling mechanism and the fish-cleaning mechanism, where the fish are descaled and cleaned. Multiple processes can be completed in one machine, greatly improving the efficiency of fish-killing.

[0004] For example, in the prior art, Chinese Patent No. CN112841279B discloses a fish-killing machine, including: a conveying device, which includes at least three fish-feeding clamping mechanisms that adapt to the shape of the fish, each of the fish-feeding clamping mechanisms including a pair of conveying wheels for clamping and conveying the fish forward; a descaling device, which is disposed between two of the fish-feeding clamping mechanisms, the descaling device including two nozzle assemblies and a drive mechanism for driving the two nozzle assemblies to move linearly up and down, the two nozzle assemblies including a nozzle rod and one or more nozzles disposed on the nozzle rod for spraying high-pressure water to remove fish scales, the high-pressure water sprayed by the nozzles being obliquely directed toward the fish conveyed between the two nozzle assemblies; and a cutting device, which is used to cut the fish after scale removal during the fish conveying process of the conveying device, removing the scales cleanly without damaging the fish meat.

[0005] Based on the above materials, when pre-treating fish, manual scaling requires repeated force, is time-consuming, inefficient, and causes scales to fly and pollute the environment. Knife operation can easily cause cuts, posing significant safety hazards. Existing fish processing tools have limited functions, lacking visceration and slicing capabilities, and require frequent equipment replacement, making it difficult to meet the needs of high efficiency, safety, convenience, and multi-functionality. Therefore, we propose an intelligent fish pre-treatment machine. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This intelligent fish pretreatment machine, through the integrated design of the scaling mechanism, viscera removal mechanism and cutting mechanism, realizes the fully automated processing of fish from scaling, opening the abdomen and removing viscera to cutting. Compared with traditional manual processing and existing single-function processing equipment, it greatly reduces the process connection time and equipment replacement frequency, significantly improves the overall efficiency of fish pretreatment, and can better adapt to the needs of various large-scale processing scenarios.

[0018] 2. By using a soft silicone scraper in the scaling mechanism, combined with the differentiated diameter layout of the first and second scraping rollers, the scales can be efficiently removed while effectively avoiding damage to the fish meat. At the same time, the sliding and adjustable structure of the scaling baffle can adapt to the scaling needs of fish of different sizes, improving the versatility and processing stability of the equipment and solving the problems of existing processing equipment that easily damage fish and have poor adaptability.

[0019] 3. Through the coordinated operation of the V-shaped second conveyor belt, ultrasonic ranging and recognition components, and elastic grippers in the viscera removal mechanism, the position of the fish body can be accurately located and stably clamped and transported, achieving precise control of the opening position and complete grasping of the viscera; in addition, the auxiliary expansion effect of the fish belly expansion plate further improves the thoroughness of viscera removal, avoiding the impact of viscera residue on the quality of the fish meat, while the elastic grippers made of silicone material can also reduce the clamping damage to the fish body.

[0020] 4. The integrated rinsing components are distributed at key process nodes such as scaling, gutting, and cutting, which can rinse the fish body and equipment processing parts in real time, effectively preventing the adhesion of pollutants such as fish scales and internal organ residues. This avoids environmental pollution caused by scale splashing and residue accumulation during processing, while ensuring the hygiene and safety of fish meat processing and reducing the difficulty of subsequent cleaning.

[0021] 5. The combination of a multi-dimensional robotic arm and an ultrasonic ranging and recognition component in the segmentation mechanism, along with the arc-shaped limiting frame and flipping rollers of the fish body adjustment component, enables precise positioning, posture adjustment, and personalized segmentation of the fish body after evisceration. It can complete segmentation processing of different specifications according to needs. The sliding cooperation design between the traveling trolley and the processing table further improves the flexibility and accuracy of the segmentation position. Compared with the traditional fixed cutting method, it has stronger adaptability, can meet different segmentation needs, improve the diversity of pre-processed products, and enhance the market applicability of the equipment.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-4 The present invention provides the following technical solution: a smart fish pretreatment machine, including a processing machine body 1, the processing machine body 1 is composed of a processing table 3 and a frame 2, the end of the processing table 3 is provided with a scaling mechanism for descaling fish, the scaling mechanism includes a fixed frame 5 fixedly installed on the surface of the processing table 3 and a first movable frame 6 slidably installed on the surface of the processing table 3, the side wall of the first movable frame 6 is provided with a drive shaft 8, and the outer wall of the drive shaft 8 is provided with a first scraping roller 9 and a second scraping roller 10, the end of the processing table 3 is provided with a first conveyor belt 4, and the discharge end of the first conveyor belt 4 is provided with a scaling baffle 12.

[0035] like Figures 2-4As shown, there are two sets of fixed frames 5 and two sets of first movable frames 6, and the fixed frames 5 and the first movable frames 6 are symmetrically distributed on both sides of the first conveyor belt 4. The first movable frame 6 is located between the two sets of fixed frames 5. The side wall of the first movable frame 6 is provided with a rinsing component for cleaning the fish body. There are evenly distributed adaptive springs 7 between the first movable frame 6 and the fixed frames 5. The drive shaft 8 is perpendicular to the first conveyor belt 4, and the end of the drive shaft 8 is provided with a drive device. There are two sets of first scraping rollers 9 symmetrically arranged on the outer wall of the drive shaft 8, and two sets of second scraping rollers 10 symmetrically arranged between the two sets of first scraping rollers 9. The diameter of the first scraping roller 9 is larger than the diameter of the second scraping roller 10. The outer walls of the first scraping roller 9 and the second scraping roller 10 are provided with scraper blades 11 distributed at equal intervals, and the scraper blades 11 are made of soft silicone.

[0036] like Figure 3 As shown, the scraping baffle 12 is slidably connected to the processing table 3, and the outer wall of the scraping baffle 12 is provided with a rack 13. The surface of the processing table 3 is fixedly mounted with a drive motor 14, and the output end of the drive motor 14 is fixedly mounted with a drive gear 15, and the drive gear 15 is meshed with the rack 13.

[0037] After the scaling mechanism is activated, the drive unit drives the drive shaft 8 to rotate at high speed, which in turn drives the first scraping roller 9 and the second scraping roller 10 to rotate synchronously. The soft silicone scrapers 11 on the outer walls of the two sets of scraping rollers move in a circular motion with the rollers. The user places the fish to be processed on the first conveyor belt 4, which transports the fish to the scaling area. During the process, the adaptive spring 7 between the first moving frame 6 and the fixed frame 5 automatically extends and retracts according to the size of the fish, pushing the first moving frame 6 closer to or away from the fixed frame 5, so that the scraping rollers on both sides fit tightly against the sides and abdominal curves of the fish. Since the diameter of the first scraping roller 9 is larger than that of the second scraping roller 10, a differentiated scaling layout is formed, which, combined with the soft silicone... The elastic deformation characteristics of the scraper 11 allow it to efficiently peel off fish scales through reasonable friction during rotation, while avoiding damage to the fish skin. During the scraping process, the rinsing components on the side wall of the first moving frame 6 simultaneously spray high-pressure water containing 3%-5% salt solution and 1%-2% baking soda solution. This helps to soften and rinse off the fish scales, and removes mucus from the surface of the fish. Before the scraping is completed, the drive motor 14 drives the drive gear 15 to rotate. Through the meshing of the gear and rack 13, the scraping baffle 12 is driven to slide open along the processing table 3, providing a passage for the fish to enter the subsequent process. The detached fish scales and rinsing wastewater are collected in a concentrated manner to avoid environmental pollution.

[0038] Example 2: Please refer to Figure 1 and Figures 5-8Based on Embodiment 1, an internal organ removal mechanism is also disclosed, the specific structure of which is as follows: The surface of the processing table 3 is provided with an internal organ removal mechanism consisting of an abdominal opening component and an internal organ grasping component. The abdominal opening component includes a second conveyor belt 16 disposed on the surface of the processing table 3. The bottom of the frame 2 is provided with a lifting frame 17, and the bottom end of the lifting frame 17 is provided with an abdominal opening blade 18. The side wall of the lifting frame 17 is provided with a rinsing component and an ultrasonic ranging and identification component. The second conveyor belt 16 is correspondingly disposed with the first conveyor belt 4, and two sets of the second conveyor belt 16 are symmetrically disposed, and the two sets of the second conveyor belt 16 are designed in a V shape.

[0039] like Figures 5-8 As shown, the viscera gripping assembly includes a second movable frame 20 set at the top of the frame 2, and an elastic gripper 21 at the bottom of the second movable frame 20. The bottom end of the lifting frame 17 is provided with a fish belly expansion plate 19, and the end of the second conveyor belt 16 is provided with a conveyor chain 22, and a waste plate 23 is fixedly installed on the outer wall of the conveyor chain 22.

[0040] like Figure 7 and Figure 8 As shown, the outer wall of the elastic gripper 21 is provided with an ultrasonic ranging and identification component, and the elastic gripper 21 is made of silicone material. The elastic gripper 21 is located above the second conveyor belt 16. Two sets of fish belly expansion plates 19 are symmetrically arranged, and the end of the fish belly expansion plate 19 is provided with a driving device.

[0041] After scaling, the fish is conveyed by the first conveyor belt 4 to the V-shaped second conveyor belt 16. The two symmetrically distributed second conveyor belts 16 form a clamping channel, stably conveying the fish forward. Under the positioning guidance of the ultrasonic ranging and identification component, the lifting frame 17 at the bottom of the frame 2 accurately descends to the corresponding height of the fish belly. After the abdominal opening blade 18 is activated, it completes the precise cutting of the fish belly along with the fish body. During the cutting process, the rinsing component on the side wall of the lifting frame 17 immediately washes away the residual scales and mucus on the surface of the fish body to prevent contamination of the fish meat. After the abdominal opening is completed, the two sets of fish belly expansion plates 19 at the bottom of the lifting frame 17 open synchronously under the drive of the drive device, opening the fish belly to expose the internal organs. The gripping mechanism provides operating space. At this time, the second movable frame 20 at the top of the frame 2 moves the elastic gripper 21 to above the fish belly. The ultrasonic ranging and identification component on the outer wall of the elastic gripper 21 accurately locates the internal organs. The silicone elastic gripper 21 adaptively adjusts its opening and closing degree according to the internal space of the fish belly, fully enveloping the internal organs. The gripping force is controlled by pure mechanical linkage to avoid the internal organs falling off or the fish meat being damaged. After the gripping is completed, the elastic gripper 21 moves above the conveyor chain 22 and releases the internal organs onto the waste plate 23. The conveyor chain 22 then transports the waste away from the processing area. At the same time, the rinsing component rinses the fish abdominal cavity and the elastic gripper 21 to ensure the hygiene of subsequent processing.

[0042] Example 3: Please refer to Figure 1 Figure 9 and Figure 10 Based on Embodiment 1, a segmentation mechanism is also disclosed, the specific structure of which is as follows: The end of the processing table 3 away from the scaling mechanism is provided with a segmentation mechanism for segmenting fish after removing internal organs. The segmentation mechanism includes a third conveyor belt 28 set at the end of the processing table 3, and a traveling trolley 29 slidably installed with the processing table 3 is provided on the side wall of the third conveyor belt 28. A multi-dimensional robotic arm 30 is provided on the top of the traveling trolley 29, and a segmentation blade 31 is provided at the end of the multi-dimensional robotic arm 30. An ultrasonic ranging and identification component is provided on the outer wall of the multi-dimensional robotic arm 30. A fish body adjustment component is provided at the end of the third conveyor belt 28 near the second conveyor belt 16.

[0043] like Figure 9 and Figure 10 As shown, the fish body adjustment assembly includes a turning platform 24 located at the end of the third conveyor belt 28, and two sets of limit frames 25 are symmetrically installed on the side wall of the turning platform 24. The limit frames 25 are generally arc-shaped, and the outer wall of the limit frames 25 is in contact with the fish body. Servo motors 26 are provided on both sides of the turning platform 24, and a turning roller 27 is provided at the output end of the servo motor 26. The outer wall of the turning roller 27 is in contact with the fish body. A rinsing assembly is provided on the side wall of the turning platform 24.

[0044] After eviscerating, the fish is conveyed by the second conveyor belt 16 to the fish body adjustment assembly at the end of the third conveyor belt 28. Servo motors 26 on both sides of the flipping platform 24 drive the flipping rollers 27 to rotate, and the arc-shaped limiting frame 25 guides and limits the fish body, flipping it from a vertically conveyed position to a horizontal one for easier subsequent cutting. Simultaneously, the rinsing assembly on the side wall of the flipping platform 24 performs high-pressure rinsing on the entire fish body and abdominal cavity to remove residual blood and dirt. The third conveyor belt 28 transports the adjusted fish body to the cutting area. The traveling trolley 29 slides along the processing table 3 to adjust its position, and the ultrasonic ranging and recognition assembly on the outer wall of the multi-dimensional robotic arm 30 scans and establishes the fish body. The system accurately identifies information such as fish size and bone location. Based on the identified data, the multi-dimensional robotic arm 30 guides the cutting blade 31 to the preset cutting position through lateral movement and four-axis linkage. The pressing device simultaneously fixes the fish body to prevent displacement during cutting. According to the user's preset cutting requirements, the cutting blade 31 can achieve various cutting methods such as straight cutting, oblique cutting, and vertical cutting. When cutting hard parts such as gill cartilage, the blade head automatically switches to a serrated cutting trajectory. After cutting, the multi-dimensional robotic arm 30 resets, and the cut fish meat is transported to the discharge end by the third conveyor belt 28. The internal rinsing component of the equipment automatically cleans the cutting area and blades to prepare for the next use.
