Description

Technical Field

[0001] This utility model relates to the technical field of squirrel fish cutting equipment, and in particular to a squirrel fish cutting machine. Background Technology

[0002] With the improvement of people's living standards and the increasing demands for food processing efficiency, the industrialization and standardization of traditional dishes have gradually become an important development direction in the catering industry. Squirrel Fish, a traditional dish with a long history and wide appeal, is renowned for its unique decorative cutting technique and beautiful shape. During its preparation, the surface of the fish needs to be cut with even, regular cross-shaped cuts to create a fluffy shape resembling a squirrel's tail after cooking. For a long time, this cutting process relied mainly on manual operation by chefs, requiring a high level of skill from the operators.

[0003] However, relying entirely on manual cutting of squirrel fish presents numerous problems. First, manual cutting is labor-intensive, and prolonged operation can easily lead to operator fatigue, affecting production efficiency. Second, it is difficult to maintain a high degree of consistency in the depth, spacing, and angle of the cuts, resulting in inconsistent product quality and hindering standardized mass production. Furthermore, in high-demand environments, the slow speed of manual cutting becomes a bottleneck restricting large-scale processing and failing to meet the modern food industry's demands for efficient, stable, and consistent production.

[0004] The purpose of this invention is to solve the problems of existing squirrel fish cutting methods that rely on manual labor, resulting in high labor intensity, low cutting efficiency, and inconsistent quality. Utility Model Content

[0005] The purpose of this invention is to solve the problems of manual cutting of squirrel fish, which is labor-intensive, inefficient, and inconsistent in quality. This invention adopts the following technical solution:

[0006] A squirrel fish cutting machine includes a worktable with a conveying mechanism and a flower-cutting mechanism mounted on it. The flower-cutting mechanism includes a first cutting mechanism, a second cutting mechanism, and a third cutting mechanism. The structure of the second cutting mechanism is mirror-symmetrical to that of the first cutting mechanism. The conveying mechanism includes a conveyor belt and a first driving member.

[0008] As described above, in a squirrel fish cutting machine, the first cutting blade is a circular blade, and the tilt angle of the first cutting blade is positively correlated with its diameter; the larger the tilt angle, the larger the diameter of the first cutting blade.

[0009] As described above, in a squirrel fish cutting machine, the third cutting mechanism includes a support with a groove. A second driving member is mounted on the support, and a sliding plate slidably connected to the support is mounted at the power output point of the second driving member. The second driving member drives the sliding plate to move laterally. A flexible transmission mechanism is mounted on the sliding plate, including a belt. A clamping block fixedly connected to the support is mounted on one side of the belt, and a slider disposed in the groove is mounted on the other side of the belt. A blade holder is mounted at one end of the slider, and a second drive shaft is mounted on the blade holder. A second cutting blade is sleeved on the second drive shaft. A drive gear is driven through the second drive shaft, and the drive gear meshes with a rack. The rack is fixedly connected to the bottom of the support.

[0010] As described above, in a squirrel fish cutting machine, the first drive component is driven by a first gear shaft, which is driven by the conveyor belt. The first gear shaft is driven by a second gear shaft, one end of which is driven by the first drive shaft, and the other end of which is driven by a third gear shaft. The third gear shaft is driven by the first drive shaft of the second cutting mechanism, and the third gear shaft is driven by a fourth gear shaft, which is driven by the conveyor belt.

[0011] As described above, in a squirrel fish cutting machine, the worktable is equipped with a suction mechanism. The worktable includes a support frame, and the suction mechanism includes a funnel mounted on the support frame. The funnel is positioned below the bearing surface of the conveyor belt. One end of the support frame is equipped with a connecting pipe that communicates with the funnel. One end of the connecting pipe is equipped with a collection box, and the collection box is equipped with a suction component. The suction component is used to generate negative pressure inside the collection box.

[0012] As described above, in a squirrel fish cutting machine, the funnel includes a flow guide box, the top of which is fitted with a cover plate, the cover plate having a plurality of leakage holes, and the conveyor belt having a plurality of through holes.

[0013] As described above, in a squirrel fish cutter, the bottom of the flow guide box is provided with an inclined part, which is inclined toward the direction of the connecting pipe.

[0014] As described above, in a squirrel fish cutting machine, a pair of funnels are provided below each of the first cutting mechanism, the second cutting mechanism, and the third cutting mechanism.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 8As shown, this utility model proposes a squirrel fish cutting machine, including a worktable 1. A conveying mechanism 2 and a cutting mechanism 3 are installed on the worktable 1. The cutting mechanism 3 includes a first cutting mechanism 31, a second cutting mechanism 32, and a third cutting mechanism 33. The structure of the second cutting mechanism 32 is mirror-symmetrical to that of the first cutting mechanism 31. The conveying mechanism 2 includes a conveyor belt 21 and a first driving member 22. The first driving member 22 is used to synchronously drive the conveyor belt 21 to rotate and to drive the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33 to perform cutting actions. The conveyor belt 21 has a through groove 211, which is used to accommodate the fish tail and provide clearance for cutting. In use, the half-cut fish body is placed on the conveyor belt 21, with the tail portion hanging into the through groove 211 on the conveyor belt 21. The two sides of the fish meat are symmetrically placed on the conveyor belt surface on both sides of the through groove 211, achieving stable positioning. After the equipment is started, the first drive unit 22 synchronously drives the conveyor belt 21 to operate, continuously conveying the fish body along the worktable 1 to the workstation of the flower cutting mechanism 3. At the same time, it drives the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33 to perform cutting actions in sequence. Among them, the first cutting mechanism 31 and the second cutting mechanism 32, which is structurally symmetrical with it, cut diagonal lines in opposite directions on both sides of the fish body. Finally, the third cutting mechanism 33 can cut horizontal lines on both sides of the fish body to form a cross-shaped flower pattern.

[0031] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first cutting mechanism 31 includes a first drive shaft 311, on which at least two first cutting blades 312 are sleeved. The cutting surfaces of the first cutting blades 312 are deviated from the vertical direction to the same side at different tilt angles, and the bottom ends of each first cutting blade 312 are all located on the same horizontal reference plane. The first cutting blades 312 are circular blades, and the tilt angle of the first cutting blade 312 is positively correlated with its diameter; the larger the tilt angle, the larger the diameter of the first cutting blade 312. When slicing fish meat, the first cutting mechanism 31 drives multiple first cutting blades 312 to rotate synchronously through the first drive shaft 311 to perform cutting operations. Each first cutting blade 312 is installed at different tilt angles deviating from the vertical direction to the same side, and its bottom ends are all located on the same horizontal reference plane, ensuring that the blade tip height is consistent during cutting. Since the cutting blades are circular blades, their diameter is positively correlated with the tilt angle, that is, the larger the tilt angle, the larger the diameter. When slicing the fish, the thicker parts of the fish are cut with a smaller diameter knife that is more vertical and has a smaller angle of inclination, while the thinner tail is cut with a larger diameter knife that has a larger angle of inclination. By using the principle of bevel, the actual cutting depth of different thickness areas can be kept consistent without adjusting the height of the knife.

[0032] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first cutting mechanism 31 includes a frame, and limit plates 313 are provided on both sides of the first cutting blade 312. The limit plates 313 are rotatably connected to the first transmission shaft 311, and the limit plates 313 are fixedly connected to the frame. The limit plates 313 are rotatably connected to the first transmission shaft 311 through bearings or bushings, so that they can rotate synchronously with the transmission shaft without axial displacement when the transmission shaft rotates. At the same time, the outer end of the limit plates 313 is fixedly connected to the frame of the first cutting mechanism, providing rigid support. This structure ensures that each first cutting blade 312 maintains a stable axial position and spatial posture during high-speed rotation, preventing blade movement or deviation due to vibration or cutting resistance.

[0033] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the third cutting mechanism 33 includes a support 331, the support 331 having a sliding groove 3311, a second driving member 332 mounted on the support 331, a sliding plate 333 slidably connected to the support 331 mounted at the power output point of the second driving member 332, the second driving member 332 being used to drive the sliding plate 333 to move laterally, a flexible transmission mechanism 334 mounted on the sliding plate 333, the flexible transmission mechanism 334 including a belt 3341, the belt 334... A clamping block 335, fixedly connected to the support 331, is installed on one side of the belt 3341. A slider 336, disposed in the slide groove 3311, is installed on the other side of the belt 3341. A tool holder 338 is installed at one end of the slider 336. A second drive shaft 339 is installed on the tool holder 338. A second cutting blade 3391 is sleeved on the second drive shaft 339. A drive gear 3310 is driven by the second drive shaft 339. The drive gear 3310 meshes with a rack 337. The rack 337 is fixedly connected to the bottom of the support 331. When the third cutting mechanism 33 is working, the second driving member 332 is activated, driving its power output end to drive the slide plate 333 to reciprocate laterally along the slide groove 3311 on the support 331. A flexible transmission mechanism 334 is installed on the slide plate 333. One end of its belt 3341 is fixed to the support 331 by a clamping block 335, and the other end is connected to a slider 336. The slider 336 can slide within the slide groove 3311 and connect to the tool holder 338. When the slide plate 333 moves, since the clamping block 335 is fixed, the belt 3341 generates relative motion under the drive of the slide plate 333, thereby driving the slider 336 to move along the slide groove 3311, realizing the lateral feed of the tool holder 338. At the same time, the movement of the slider 336 drives the transmission gear 3310 connected to it to roll along the rack 337 fixed to the bottom of the support 331, causing the transmission gear 3310 to rotate, which in turn drives the second transmission shaft 339 and the second cutting blade 3391 to rotate at high speed, realizing the synchronous action of cutting while feeding. The total lateral travel of the tool holder 338 is the sum of the movement of the slider 336 and the overall displacement of the slide plate 333, ensuring that the cutting blade has sufficient travel to complete the entire cutting.

[0034] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the first drive member 22 is drivenly connected to a first gear shaft 23, the first gear shaft 23 is drivenly connected to the conveyor belt 21, the first gear shaft 23 is drivenly connected to a second gear shaft 24, one end of the second gear shaft 24 is drivenly connected to the first drive shaft 311, the other end of the second gear shaft 24 is drivenly connected to a third gear shaft 25, the third gear shaft 25 is drivenly connected to the first drive shaft 311 of the second cutting mechanism 32, the third gear shaft 25 is drivenly connected to a fourth gear shaft 26, and the fourth gear shaft 26 is drivenly connected to the conveyor belt 21. The first drive unit 22 serves as the main power source for the entire machine. After startup, it drives the first gear shaft 23 to rotate via a transmission connection. The first gear shaft 23 is connected to the conveyor belt 21, directly driving the conveyor belt to achieve continuous transport of the fish. On the other hand, the first gear shaft 23 transmits power to the second gear shaft 24. One end of the second gear shaft 24 is connected to the first drive shaft 311 of the first cutting mechanism 31, driving it to rotate and drive the first cutting blade 312 to perform the cutting operation. The other end transmits power to the first drive shaft 311 of the second cutting mechanism 32 via the third gear shaft 25, achieving synchronous cutting on the symmetrical side. At the same time, the third gear shaft 25 is also connected to the fourth gear shaft 26, which is again connected to the conveyor belt 21, forming a multi-point drive structure to ensure that the conveyor belt 21 runs smoothly and synchronously, avoiding slippage or deviation caused by uneven load.

[0035] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the workbench 1 is equipped with a suction mechanism 4. The workbench 1 includes a support frame 11. The suction mechanism 4 includes a funnel 41 mounted on the support frame 11. The funnel 41 is disposed below the bearing surface of the conveyor belt 21. A connecting pipe 42 communicating with the funnel 41 is installed at one end of the support frame 11. A collection box 44 is installed at one end of the connecting pipe 42. A suction component 43 is installed in the collection box 44. The suction component 43 is used to generate negative pressure in the inner cavity of the collection box 44. The funnel 41 includes a flow guide box 411. A cover plate 412 is installed on the top of the flow guide box 411. The cover plate 412 has a plurality of leakage holes 413. The conveyor belt 21 has a plurality of through holes. An inclined portion is provided at the bottom of the flow guide box 411, and the inclined portion is inclined towards the connecting pipe 42. When the suction mechanism 4 is working, the suction component 43 is activated, creating a negative pressure inside the collection box 44. This negative pressure is transmitted to the guide box 411 of the funnel 41 through the connecting pipe 42. Waste materials such as chips and fish scales generated during the cutting process fall from the through holes on the conveyor belt 21, pass through the drain holes 413 on the cover plate 412, and enter the interior of the guide box 411. The bottom of the guide box 411 is provided with an inclined part that slopes towards the connecting pipe 42, which facilitates the waste materials to automatically slide towards the connecting pipe side under the action of gravity and airflow. Finally, the waste materials are sucked into the collection box 44 through the connecting pipe 42 for centralized storage, realizing continuous automatic cleaning of waste materials.

[0036] Optionally, in some embodiments, a pair of funnels 41 are provided below each of the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33. The presence of pairs of funnels 41 below each cutting mechanism allows for precise coverage of the main cutting area, significantly improving waste collection efficiency, preventing waste from splashing or accumulating inside the equipment, and maintaining a clean and hygienic working area.

[0037] Example 1:

[0038] This utility model proposes a squirrel fish cutting machine, including a worktable 1. A conveying mechanism 2 and a cutting mechanism 3 are installed on the worktable 1. The cutting mechanism 3 includes a first cutting mechanism 31, a second cutting mechanism 32, and a third cutting mechanism 33. The structure of the second cutting mechanism 32 is mirror-symmetrical to that of the first cutting mechanism 31. The conveying mechanism 2 includes a conveyor belt 21 and a first driving member 22. The first driving member 22 is used to synchronously drive the conveyor belt 21 to rotate and to drive the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33 to perform cutting actions. The conveyor belt 21 has a through groove 211, which is used to accommodate the fish tail and provide clearance for cutting. In use, the half-cut fish body is placed on the conveyor belt 21, with the tail portion hanging into the through groove 211 on the conveyor belt 21. The two sides of the fish meat are symmetrically placed on the conveyor belt surface on both sides of the through groove 211, achieving stable positioning. After the equipment is started, the first drive unit 22 synchronously drives the conveyor belt 21 to operate, continuously conveying the fish body along the worktable 1 to the workstation of the flower cutting mechanism 3. At the same time, it drives the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33 to perform cutting actions in sequence. Among them, the first cutting mechanism 31 and the second cutting mechanism 32, which is structurally symmetrical with it, cut diagonal lines in opposite directions on both sides of the fish body. Finally, the third cutting mechanism 33 can cut horizontal lines on both sides of the fish body to form a cross-shaped flower pattern.

[0039] The first cutting mechanism 31 includes a first drive shaft 311, on which at least two first cutting blades 312 are mounted. The cutting surfaces of the first cutting blades 312 are offset from the vertical direction to the same side at different tilt angles, and the bottom ends of each first cutting blade 312 are all on the same horizontal reference plane. The first cutting blades 312 are circular blades, and the tilt angle of the first cutting blade 312 is positively correlated with its diameter; the larger the tilt angle, the larger the diameter of the first cutting blade 312. When slicing fish meat, the first cutting mechanism 31 drives multiple first cutting blades 312 to rotate synchronously through the first drive shaft 311 to perform the cutting operation. Each first cutting blade 312 is installed offset from the vertical direction to the same side at different tilt angles, and its bottom end is located on the same horizontal reference plane to ensure that the blade tip height is consistent during cutting. Since the cutting blades are circular blades, their diameter is positively correlated with the tilt angle; that is, the larger the tilt angle, the larger the diameter. When slicing the fish, the thicker parts of the flesh are cut with a smaller diameter blade at a smaller angle, closer to vertical, while the thinner tail is cut with a larger diameter blade at a larger angle. Utilizing the principle of bevel cutting, the actual cutting depth remains consistent across different thickness areas without adjusting the blade height. The first cutting mechanism 31 includes a frame, with limit plates 313 on both sides of the first cutting blade 312. The limit plates 313 are rotatably connected to the first drive shaft 311 and fixedly connected to the frame. The limit plates 313 are rotatably connected to the first drive shaft 311 via bearings or bushings, allowing them to rotate synchronously without axial displacement when the drive shaft rotates. Simultaneously, the outer end of the limit plates 313 is fixedly connected to the frame of the first cutting mechanism, providing rigid support. This structure ensures that each first cutting blade 312 maintains a stable axial position and spatial posture during high-speed rotation, preventing blade movement or deviation due to vibration or cutting resistance.

[0040] The third cutting mechanism 33 includes a support 331, which has a groove 3311. A second driving member 332 is installed on the support 331. A slide plate 333 that is slidably connected to the support 331 is installed at the power output point of the second driving member 332. The second driving member 332 is used to drive the slide plate 333 to move laterally. A flexible transmission mechanism 334 is installed on the slide plate 333. The flexible transmission mechanism 334 includes a belt 3341. A clamping block 335 that is fixedly connected to the support 331 is installed on one side of the belt 3341. A slider 336 that is set in the groove 3311 is installed on the other side of the belt 3341. A knife holder 338 is installed at one end of the slider 336. A second transmission shaft 339 is installed on the knife holder 338. A second cutting blade 3391 is sleeved on the second transmission shaft 339. A transmission gear 3310 is connected to the second transmission shaft 339. The transmission gear 3310 meshes with a rack 337. The rack 337 is fixedly connected to the bottom of the support 331. When the third cutting mechanism 33 is working, the second driving component 332 is activated, driving its power output end to move the slide plate 333 back and forth along the slide groove 3311 on the support 331. A flexible transmission mechanism 334 is installed on the slide plate 333. One end of its belt 3341 is fixed to the support 331 by a clamping block 335, and the other end is connected to a slider 336. The slider 336 can slide within the slide groove 3311 and connect to the tool holder 338. When the slide plate 333 moves, since the clamping block 335 remains stationary, the belt 3341 moves relative to the slide plate 333, thereby driving the slider 336 to move along the slide groove 3311, realizing the lateral feed of the tool holder 338. Simultaneously, the movement of the slider 336 drives the transmission gear 3310 connected to it to roll along the rack 337 fixed to the bottom of the support 331, causing the transmission gear 3310 to rotate, which in turn drives the second transmission shaft 339 and the second cutting blade 3391 to rotate at high speed, achieving synchronous action of simultaneous cutting and feeding. The total lateral travel of the tool holder 338 is the sum of the movement of the slider 336 and the overall displacement of the slide plate 333, ensuring that the cutting tool has enough travel to complete the entire cutting process.

[0041] The first drive unit 22 is connected to a first gear shaft 23, which is connected to the conveyor belt 21. The first gear shaft 23 is connected to a second gear shaft 24, one end of which is connected to a first drive shaft 311. The other end of the second gear shaft 24 is connected to a third gear shaft 25, which is connected to the first drive shaft 311 of the second cutting mechanism 32. The third gear shaft 25 is connected to a fourth gear shaft 26, which is connected to the conveyor belt 21. The first drive unit 22 serves as the main power source for the entire machine. After startup, it drives the first gear shaft 23 to rotate via a transmission connection. The first gear shaft 23 is connected to the conveyor belt 21, directly driving the conveyor belt to achieve continuous transport of the fish. On the other hand, the first gear shaft 23 transmits power to the second gear shaft 24. One end of the second gear shaft 24 is connected to the first drive shaft 311 of the first cutting mechanism 31, driving it to rotate and drive the first cutting blade 312 to perform the cutting operation. The other end transmits power to the first drive shaft 311 of the second cutting mechanism 32 via the third gear shaft 25, achieving synchronous cutting on the symmetrical side. At the same time, the third gear shaft 25 is also connected to the fourth gear shaft 26, which is again connected to the conveyor belt 21, forming a multi-point drive structure to ensure that the conveyor belt 21 runs smoothly and synchronously, avoiding slippage or deviation caused by uneven load.

[0042] The workbench 1 includes a support frame 11. The suction mechanism 4 includes a funnel 41 mounted on the support frame 11. The funnel 41 is positioned below the bearing surface of the conveyor belt 21. A connecting pipe 42, communicating with the funnel 41, is installed at one end of the support frame 11. A collection box 44 is installed at one end of the connecting pipe 42. A suction component 43 is installed in the collection box 44 to create a negative pressure inside the collection box 44. The funnel 41 includes a guide box 411. A cover plate 412 is installed on the top of the guide box 411. The cover plate 412 has several holes 413. The conveyor belt 21 has several through holes. An inclined portion is provided at the bottom of the guide box 411, which is inclined towards the connecting pipe 42. When the suction mechanism 4 is working, the suction component 43 is activated, creating a negative pressure inside the collection box 44. This negative pressure is transmitted to the guide box 411 of the funnel 41 through the connecting pipe 42. During the cutting process, debris, fish scales, and other waste materials fall through the through holes on the conveyor belt 21, pass through the drain holes 413 on the cover plate 412, and enter the guide box 411. The bottom of the guide box 411 has an inclined section that slopes towards the connecting pipe 42, allowing the waste materials to automatically slide towards the connecting pipe under the influence of gravity and airflow. Finally, the waste materials are sucked into the collection box 44 through the connecting pipe 42 for centralized storage, achieving continuous automatic waste cleaning. A pair of funnels 41 are correspondingly provided below each of the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33. The pair of funnels 41 below each cutting mechanism can accurately cover the main cutting area, significantly improving waste collection efficiency, preventing waste from splashing or accumulating inside the equipment, and maintaining a clean and hygienic working area.

[0043] Specifically, the working principle of this invention is as follows:

[0044] When the squirrel fish cutting machine is in operation, the half-cut fish is first placed on the conveyor belt 21, with the tail portion hanging into the through groove 211 on the conveyor belt. The fish meat is symmetrically distributed on both sides of the through groove for stable positioning. After the equipment is started, the first drive unit 22 acts as the main power source, synchronously driving the conveyor belt 21 and the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33 to perform cutting actions through the transmission system consisting of the first gear shaft 23, the second gear shaft 24, the third gear shaft 25, and the fourth gear shaft 26. The fish is smoothly transported to each cutting station along the conveyor belt 21, realizing continuous automatic processing.

[0045] During the cutting process, the first cutting mechanism 31 and the mirror-symmetrically arranged second cutting mechanism 32 first perform oblique cuts on both sides of the fish body. Multiple first cutting blades 312 in the first cutting mechanism 31 are mounted on the first drive shaft 311, with the bottom ends of each blade on the same horizontal reference plane, and their inclination angles positively correlated with their diameters. Thicker fish meat is cut nearly vertically by blades with smaller inclination angles and diameters, while thinner fish meat is cut obliquely by blades with larger inclination angles and diameters. The principle of bevels ensures consistent cutting depth across different thickness areas, forming uniform oblique cuts. A limiting plate 313 is fixed to the frame and sleeved on the drive shaft to ensure axial stability of the blades during high-speed rotation. Subsequently, the third cutting mechanism 33 performs horizontal cutting: the second driving member 332 drives the slide plate 333 to move laterally, and drives the slider 336 and the tool holder 338 to move through the flexible transmission mechanism 334. At the same time, the transmission gear 3310 on the slider 336 rolls along the fixed rack 337, causing the second transmission shaft 339 to drive the second cutting blade 3391 to rotate, so as to realize the synchronization of cutting and cutting, and complete the formation of the cross-shaped cutter.

[0046] Waste materials such as debris and fish scales generated during the cutting process fall through the through holes 211 on the conveyor belt 21 and enter the paired funnels 41 located below the first cutting mechanism 31, the second cutting mechanism 32, and the third cutting mechanism 33. The cover plate 412 at the top of the funnel 41 is provided with a leakage hole 413, and the bottom is provided with an inclined part that slopes towards the connecting pipe 42. Under the action of the suction component 43, a negative pressure is formed in the collection box 44. The waste materials slide along the inclined part into the connecting pipe 42 under the combined action of gravity and airflow, and are finally sucked into the collection box 44 for centralized processing, realizing efficient and automatic cleaning of processing waste, maintaining the cleanliness of the equipment and the hygiene of the food processing environment.

[0047] In summary, this invention solves the problems of existing squirrel fish cutting methods that rely on manual labor, resulting in high labor intensity, low cutting efficiency, and inconsistent quality.
