Technical Field
[0001] This utility model relates to the field of snakehead fish processing technology, specifically to a high-precision micro-cutting device for snakehead fish fillets. Background Technology
[0002] Snakehead fish, also known as live fish, is cylindrical in the front and laterally compressed in the back. Its grayish-black body surface is covered with irregular black spots. It has auxiliary respiratory organs (supra-branch organs) and can float to the surface to breathe when oxygen is scarce. It is extremely adaptable. Its flesh is tender and has a higher protein content than chicken and beef. It contains 18 kinds of amino acids and minerals such as calcium and phosphorus. It has the effects of promoting lactation, replenishing blood, and dispelling wind and treating malnutrition. It is suitable for people with weak constitution and anemia.
[0003] In the processing of snakehead fish, after the live fish is scaled by a descaling machine, the head and tail are manually removed, the fish bones are removed along the midline of the back, the fish meat and skin are separated, and then the cutting mechanism is set to an oblique cutting angle with a thickness of 2-3mm (which can be adjusted according to needs). Finally, the cutting mechanism is used to cut the fish body into fine slices.
[0004] Existing cutting devices typically require freezing the fish meat for 30 minutes during the slicing process of snakehead fish to achieve a slightly firm state, making it easier to cut uniform thin slices. However, the mucus covering the snakehead fish's body contains fish skin protein, which solidifies into a sticky gel at low temperatures. The polysaccharide-protein complex in the mucus forms a network structure after freezing, enhancing adhesion. This results in the fish meat adhering tightly to the frozen structure, making it difficult to separate the fish meat from the frozen structure. If forced separation is attempted, the fish meat is easily damaged, thereby reducing the accuracy of subsequent fish slice cutting. Utility Model Content
[0005] The purpose of this invention is to provide a high-precision micro-cutting device for black carp fillets, in order to solve the problem mentioned in the background art that in existing cutting devices, after freezing the fish meat for 30 minutes, the fish meat tends to stick tightly to the frozen structure, making it difficult to separate the fish meat from the frozen structure. If forcibly separated, the fish meat is easily damaged, thereby reducing the accuracy of subsequent fish fillet cutting.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A high-precision micro-cutting device for black carp fillets includes a frame; a cutting mechanism is installed inside the frame, a controller is fixedly installed on one side of the frame, a freezing box is fixedly connected to one end of the frame, a placement plate is fixedly installed inside the freezing box, a hydraulic rod is fixedly connected to one end of the freezing box, the movable rod of the hydraulic rod extends to the top of the placement plate and a movable block is fixedly installed thereon, and a guide plate is fixedly connected to the other end of the freezing box; several guide holes are opened on the surface of the placement plate, a guide box is fixedly installed at the bottom of the freezing box, and an air guide component is installed inside the guide box to guide the airflow to the top of the placement plate.
[0008] By installing a placement plate and creating airflow holes, air is guided upwards using a wind-guiding component. This allows the air to enter the holes and blow onto the blackfish fillets placed on top of the placement plate, applying a uniform pushing force to the fillets and separating them from the plate. This solves the problem that frozen fish fillets tend to adhere tightly to the frozen structure, making separation difficult. Forcibly separating the fillets could damage them, reducing the precision of subsequent fillet cutting. Therefore, the integrity of the fish fillets is ensured, thus improving the accuracy of subsequent fillet cutting.
[0009] A further improvement of this utility model is that: the air guiding component includes a partition plate one, the outer surface of which is fixedly connected to the inner wall of the guide box; a partition plate two is fixedly installed inside the guide box at the bottom of the partition plate one, the outer surface of which is fixedly connected to the inner wall of the guide box; both partition plate one and partition plate two have circular holes on their surfaces, and each circular hole is equipped with a one-way valve; a baffle plate one is slidably installed on the top of partition plate one by a spring; a movable block is provided between partition plate one and partition plate two; an electric push rod is fixedly installed at one end of the guide box, the movable rod of which extends into the interior of the guide box and is fixedly connected to one end of the movable block; and a baffle plate two is slidably installed on the bottom of partition plate two by a spring.
[0010] Using the above technical solution, if it is necessary to add airflow from the bottom of the placement plate to apply thrust to the fish meat, a fan can generally be used. However, during the blowing process, the ice on the surface of the fish meat is easy to melt and drip to the bottom, which can easily come into contact with the fan motor, leading to water leakage and malfunction of the fan, affecting the performance. In this application, through the cooperation between the air guiding components (similar to the working principle of a piston), the sealing effect between the first baffle and the first partition, the second sealing gasket and the first and second partitions and the frame, and the second baffle and the frame surface are improved by installing sealing gasket one, sealing gasket two and sealing gasket three. During the movement of the moving block driven by the electric push rod, the ice on the surface of the fish meat melts into water, and even if it flows into the interior of the guide box, it is not easy to flow to the surface of the electric push rod, thus ensuring that the electric push rod can be used normally and improving the blowing effect.
[0011] A further improvement of the present invention is that: a sealing gasket is attached to the bottom of the baffle one, and the sealing gasket one is tightly attached to the top of the partition one around the round hole; a sealing gasket two is attached to the outer surface of the movable block, and the outer surface of the sealing gasket two is tightly attached to the surfaces of the partition one, the partition two and the guide box; a sealing gasket three is attached to the bottom of the baffle two, and the bottom of the sealing gasket three is tightly attached to the surface of the guide box.
[0012] In the above-mentioned technical solution, since several guide holes are opened on the surface of the placement plate, if the shape of the guide holes is cylindrical, the airflow speed is basically fixed. At this time, the wind force blowing the fish meat may not be strong enough to separate it from the surface of the placement plate, thus reducing the effectiveness of use. In this application, by setting the guide holes to a conical shape, the outlet area is reduced, thereby concentrating the airflow and increasing the outlet wind speed. In addition, the arc transition design of the conical hole can disperse the stress distribution and reduce the stress concentration around the hole. In the freezing environment with frequent hot and cold alternation, the service life of the placement plate can be extended.
[0013] A further improvement of this utility model is that the shape of several guide holes is a cone shape with a bottom opening larger than the top opening.
[0014] In the above-mentioned technical solution, since several guide holes are opened on the surface of the placement plate, if the shape of the guide holes is cylindrical, the airflow speed is basically fixed. At this time, the wind force blowing the fish meat may not be strong enough to separate it from the surface of the placement plate, thus reducing the effectiveness of use. In this application, by setting the guide holes to a conical shape, the outlet area is reduced, thereby concentrating the airflow and increasing the outlet wind speed. In addition, the arc transition design of the conical hole can disperse the stress distribution and reduce the stress concentration around the hole. In the freezing environment with frequent hot and cold alternation, the service life of the placement plate can be extended.
[0015] A further improvement of this utility model is that the diameter of the top surface of several guide holes is less than 0.5mm.
[0016] In the above-mentioned technical solution, because several guide holes are opened on the surface of the placement plate, if the diameter of the guide holes is too large, the fish meat will be stuck inside the guide holes due to gravity, thereby increasing the adhesion between the fish meat and the placement plate and affecting the feeding effect of the fish meat. In this application, by setting the diameter of the top of the guide hole to be less than 0.5mm, where the diameter is much smaller than the fish meat, the fish meat is less likely to be stuck inside the guide hole, thereby solving the problem of the fish meat being stuck inside the guide hole due to gravity, thus facilitating the subsequent separation of the fish meat from the surface of the placement plate.
[0017] A further improvement of this utility model is that a filter plate is fixedly installed on the bottom surface of the guide box, and the filter plate is located inside the sealing gasket three.
[0018] In the above-mentioned technical solution, during the process of guiding air through the guide box into the freezer, various impurities are present in the air. If the air is guided directly, these impurities and dust are easily adsorbed, causing them to get stuck on the surface of the guide holes or adhere to the surface of the fish meat, affecting the subsequent cutting effect and reducing the cutting precision. In this application, by installing a filter plate, the air can be filtered to separate impurities and dust from the gas, preventing them from entering the interior of the guide box and from getting stuck on the surface of the guide holes or adhering to the surface of the fish meat, thereby improving the subsequent cutting effect and increasing the cutting precision.
[0019] A further improvement of this utility model is that: a number of cleaning rods are fixedly installed at the bottom of the baffle two on the inner side of the sealing gasket three. The diameter of the cleaning rods is exactly equal to the size of the filter screen holes of the filter plate, and the cleaning rods all penetrate the interior of the filter screen holes of the filter plate.
[0020] In the above-mentioned technical solution, since a filter plate is set up, the filter plate continuously filters the air. Dust and impurities are easily adhered to the surface of the filter plate, causing the filter plate to become clogged and affecting the use effect of the filter plate. In this application, by installing a cleaning rod, the baffle two can move synchronously with the cleaning rod during the up and down movement, so that it slides along the inside of the filter plate, thereby realizing automatic cleaning of the filter screen holes of the filter plate and improving the use effect of the filter plate.
[0021] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0022] 1. This utility model provides a high-precision micro-cutting device for black carp fillets. By setting a placement plate and a guide hole, the air can be guided by the air guide component to blow the air onto the black carp meat placed on top of the placement plate, applying a uniform pushing force to the fish meat, so that the fish meat is slowly separated from the placement plate. This solves the problem that fish meat tends to stick tightly to the frozen structure after freezing, making it difficult to separate the fish meat from the frozen structure. If forced to separate, it will easily damage the fish meat, thus reducing the accuracy of subsequent fish fillet cutting. Therefore, the integrity of the fish meat is ensured, thereby improving the accuracy of subsequent fish fillet cutting.
[0023] 2. This utility model provides a high-precision micro-cutting device for black carp fillets. Through the cooperation between the air guiding components, the air is guided instead of a fan. During the process of blowing air and applying pressure to the fish meat, the ice on the surface of the fish meat melts into water. Even if the water flows into the interior of the guiding box, it is not easy to flow to the surface of the electric push rod, thus ensuring that the electric push rod can be used normally, thereby improving the effect of separating the fish meat from the placement plate.
[0024] 3. This utility model provides a high-precision micro-cutting device for black carp fillets. By setting the guide hole in a conical shape, the airflow can be concentrated and the outlet wind speed can be increased. Furthermore, the arc transition design of the conical hole can disperse stress distribution and reduce stress concentration around the hole. In the freezing environment with frequent temperature changes, it can extend the service life of the placement plate. By setting the diameter of the top of the guide hole to less than 0.5mm, the fish meat is less likely to get stuck inside the guide hole, thus solving the problem of the fish meat getting stuck inside the guide hole due to gravity. This makes it easier to separate the fish meat from the surface of the placement plate later. Attached Figure Description

Detailed Implementation
[0034] The present invention will be further described in detail below with reference to the embodiments.
[0035] Example 1
[0036] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a high-precision micro-cutting device for black carp fillets, including a frame 1; a cutting mechanism 5 is provided inside the frame 1, a controller 4 is fixedly installed on one side of the frame 1, a freezing box 2 is fixedly connected to one end of the frame 1, a placement plate 9 is fixedly installed inside the freezing box 2, a hydraulic rod 7 is fixedly connected to one end of the freezing box 2, the movable rod of the hydraulic rod 7 extends to the top of the placement plate 9 and a movable block 15 is fixedly installed thereon, a guide plate 6 is fixedly connected to the other end of the freezing box 2; a plurality of guide holes 10 are opened on the surface of the placement plate 9, a guide box 3 is fixedly installed at the bottom of the freezing box 2, and an air guide component is provided inside the guide box 3, which is used to guide the airflow to the top of the placement plate 9.
[0037] In this embodiment, by installing the placement plate 9 and opening the air guide hole 10, the air is guided upward by the air guide component, allowing the air to enter the air guide hole 10 and blow onto the blackfish meat placed on top of the placement plate 9. This applies a uniform pushing force to the fish meat, causing it to separate from the placement plate 9. This solves the problem that fish meat tends to adhere tightly to the frozen structure after freezing, making it difficult to separate the fish meat from the frozen structure. If forced to separate, the fish meat is easily damaged, which reduces the accuracy of subsequent fish fillet cutting. Therefore, the integrity of the fish meat is ensured, thereby improving the accuracy of subsequent fish fillet cutting.
[0038] Example 2
[0039] like Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the air guiding component includes a partition 11, the outer surface of which is fixedly connected to the inner wall of the guide box 3. A partition 2 12 is fixedly installed inside the guide box 3 at the bottom of the partition 11, the outer surface of which is fixedly connected to the inner wall of the guide box 3. Both the partition 11 and the partition 2 12 have circular holes on their surfaces, each hole containing a one-way valve. A baffle 13 is slidably installed on the top of the partition 11 via a spring. A movable block 15 is provided between the partition 11 and the partition 2 12. One end of the guide box 3 is fixedly... An electric actuator 8 is fixedly installed. The movable rod of the electric actuator 8 extends into the interior of the guide box 3 and is fixedly connected to one end of the movable block 15. A baffle 14 is slidably installed at the bottom of the partition 2 12 by a spring. A sealing gasket 16 is attached to the bottom of the baffle 1 13. The sealing gasket 16 is tightly fitted to the top of the partition 1 11 around the round hole. A sealing gasket 2 17 is attached to the outer surface of the movable block 15. The outer surface of the sealing gasket 2 17 is tightly fitted to the surfaces of the partition 1 11, the partition 2 12 and the guide box 3. A sealing gasket 3 18 is attached to the bottom of the baffle 2 14. The bottom of the sealing gasket 3 18 is tightly fitted to the surface of the guide box 3.
[0040] If you want to add airflow from the bottom of the placement plate 9 to push the fish, you can usually use a fan. However, during the blowing process, the ice on the surface of the fish is easy to melt and drip to the bottom. This can easily come into contact with the fan motor, causing the fan to leak water and malfunction, thus affecting the performance.
[0041] In this application, the cooperation between the air guiding components (similar to the working principle of a piston) is improved by installing sealing gasket 16, sealing gasket 27 and sealing gasket 318. This improves the sealing effect between baffle 13 and partition 11, sealing gasket 27 and partition 11, partition 22 and frame 1, and baffle 24 and frame 1. During the process of the electric push rod 8 driving the movable block 15 to move, the ice on the surface of the fish meat melts into water. Even if it flows into the interior of the guide box 3, it is not easy to flow to the surface of the electric push rod 8, thereby ensuring that the electric push rod 8 can be used normally and improving the blowing effect.
[0042] like Figure 1 , Figure 3 and Figure 7 As shown, the shape of several guide holes 10 is a cone shape with a bottom opening larger than the top opening.
[0043] Because several guide holes 10 are opened on the surface of the placement plate 9, if the shape of the guide holes 10 is cylindrical, the air flow speed is basically fixed. At this time, the wind force blowing the fish meat may not be strong enough to separate it from the surface of the placement plate 9, which reduces the effect of use.
[0044] In this application, by setting the guide hole 10 into a conical shape, the outlet area is reduced, thereby concentrating the airflow and increasing the outlet wind speed. Furthermore, the arc transition design of the conical hole can disperse stress distribution and reduce stress concentration around the hole, thus extending the service life of the placement plate 9 in a freezing environment with frequent hot and cold cycles.
[0045] like Figure 1 , Figure 3 and Figure 7 As shown, the diameter of the top surface of several guide holes 10 is less than 0.5 mm.
[0046] Because several flow guide holes 10 are opened on the surface of the placement plate 9, if the diameter of the flow guide holes 10 is too large, the fish meat will be stuck into the interior of the flow guide holes 10 due to gravity, which will increase the adhesion between the fish meat and the placement plate 9 and affect the effect of feeding the fish meat.
[0047] In this application, by setting the diameter of the top of the guide hole 10 to be less than 0.5mm, where the diameter is much smaller than the fish meat, the fish meat is less likely to get stuck inside the guide hole 10, thus solving the problem of the fish meat getting stuck inside the guide hole 10 due to gravity, which makes it easier to separate the fish meat from the surface of the placement plate 9 later.
[0048] like Figure 4 , Figure 5 and Figure 6 As shown, a filter plate 19 is fixedly installed on the bottom surface of the guide box 3, and the filter plate 19 is located inside the sealing gasket 3 18.
[0049] During the process of guiding air through the guide box 3 into the freezer 2, because the air contains various impurities, if it is guided directly, the impurities and dust will be easily absorbed at the same time, causing the impurities and dust to get stuck on the surface of the guide hole 10 or adhere to the surface of the fish meat, affecting the subsequent cutting effect of the fish meat and reducing the cutting accuracy.
[0050] In this application, the air can be filtered by installing the filter plate 19, which separates impurities and dust from the gas, prevents impurities and dust from entering the interior of the guide box 3, and prevents impurities and dust from getting stuck on the surface of the guide hole 10 or adhering to the surface of the fish meat, thereby improving the subsequent cutting effect of the fish meat and improving the cutting accuracy.
[0051] like Figure 4 , Figure 5 and Figure 6 As shown, several cleaning rods 20 are fixedly installed at the bottom of the baffle 2 14 inside the sealing gasket 3 18. The diameter of the cleaning rods 20 is exactly equal to the size of the filter screen holes of the filter plate 19, and all the cleaning rods 20 penetrate the interior of the filter screen holes of the filter plate 19.
[0052] Because of the filter plate 19, the filter plate 19 continuously filters the air. Dust and impurities easily adhere to the surface of the filter plate 19, causing the filter plate 19 to become clogged and affecting the performance of the filter plate 19.
[0053] In this application, by installing the cleaning rod 20, the baffle 2 14 can move synchronously with the cleaning rod 20 during its up-and-down movement, allowing it to slide along the inside of the filter plate 19, thereby automatically cleaning the filter screen holes of the filter plate 19 and improving the performance of the filter plate 19.
[0054] The working principle of this high-precision micro-cutting device for blackfish fillets is explained in detail below.
[0055] like Figures 1-7As shown, the operator opens the protective door of the freezer 2, places the deboned fish meat on top of the placement plate 9, and then closes the protective door. The freezer 2 is then used for rapid freezing of the preheated fish. After freezing, the operator can control the electric push rod 8 to retract, causing the movable block 15 to move. This creates an adhesive force between the first partition 11 and the second partition 12, causing the second baffle 14 to move upwards. Simultaneously, the sealing gasket 16 continues to adhere tightly to the surface of the first partition 11, allowing external air to be drawn into the guide box 3. The air is then filtered using the filter plate 19. The operator then controls the electric push rod 8 to move the movable block 15 to the other end, further depressing the first partition 11. The force between the baffle plate 12 and the partition plate 14 causes the baffle plate 14 to move to the bottom, while the sealing gasket 16 separates from the surface of the partition plate 11. This allows the external air to be guided upward, passing through the surface of the guide hole 10 and blowing onto the fish meat, creating a certain and uniform force on the fish meat. This causes the fish meat to slowly separate from the surface of the placement plate 9. Once the fish meat is completely separated from the surface of the placement plate 9, the operator can use the hydraulic rod 7 to move the movable block 15 to the other end, thereby pushing the fish meat so that it slides down the surface of the guide plate 6 onto the cutting mechanism 5. Finally, the cutting mechanism 5 cuts the fish meat into fine slices.
[0056] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
