Description

Technical Field

[0001] The present invention relates to the technical field of seafood processing equipment, and specifically refers to a method for bionic extraction of yellow substance from squid. Background Art

[0002] Chinese squid, commonly known as squid, is an important seafood in my country, with a huge annual output. At the same time, the processing steps are cumbersome. When processing, it is often necessary to split and separate different parts of the squid, and separate the head, viscera and carcass of the squid from each other so that different parts can be processed according to needs. However, most of the existing squid separation equipment can only separate the head and tail, but cannot separate the viscera. It can only be done by manual operation, which is labor-intensive, time-consuming and labor-intensive. A small number of squid separation equipment can separate the viscera, but it is necessary to cut the squid trunk longitudinally to remove the viscera, which will destroy the appearance integrity of the squid. After searching, Chinese patent CN114946922A discloses a squid yellow-removing device, which includes a claw opening mechanism, a main body support mechanism, A clamping mechanism and an viscera separation device, the claw mechanism includes a tongs, a first strut, a second strut, and a drive shaft, the first strut and the second strut are arranged parallel to each other, the drive shaft is used to drive the tongs and the first strut and the second strut to approach or separate from each other, the tongs, the first strut and the second strut are all connected to the main support mechanism, the inner wall of the squid carcass is spread open when the tongs and the first strut and the second strut are separated from each other, the clamping mechanism includes a first clamping plate and a second clamping plate, the first clamping plate and the second clamping plate are both connected to the main support mechanism, the first clamping plate and the second clamping plate are suitable for approaching or moving away from each other to clamp the squid head or loosen the squid head, the The main body support mechanism is used to drive the claw mechanism and the clamping mechanism to move up and down in the vertical direction. The viscera separation device is arranged on one side of the main body support mechanism. The viscera separation device is suitable for moving up and down in the vertical direction. The viscera separation device is used to separate the squid viscera when the support clamp and the first support rod and the second support rod open the inner wall of the squid carcass. The viscera separation device includes a push knife and a push knife driving device. The push knife is connected to the push knife driving device. The push knife driving device is arranged in the vertical direction. The push knife driving device drives the push knife to move up and down in the vertical direction. The substantial deficiencies of the above patent are: first, the above patent uses the support clamp, the first support rod and the second support rod to open the inner wall of the squid carcass, and then the push knife is vertically pushed. The squid carcass is inserted into the squid carcass from the direction of the push knife, and the connection between the viscera and the squid carcass is cut off. However, in the above patent, the support pincers, the first support rod, and the second support rod are inserted into the squid carcass and rotated outward to open the squid carcass. However, the squid carcass is usually very soft, especially the fresh squid. The upper end of the squid is opened by the support pincers, the first support rod, and the second support rod, and the lower end of the squid is naturally hanging, and the squid viscera extend from the squid head to the squid tail. This is why it is easy to bring up the outer wall of the lower end of the squid carcass and turn it outward or inward when the push knife enters the squid carcass from bottom to top, resulting in the push knife being unable to accurately cut the connection between the squid viscera and the carcass wall. In addition, the squid viscera are in close contact with the inner wall of the squid carcass. When the push knife cuts, it is easy to cut the viscera or the inner wall of the squid carcass. On the one hand, it is difficult to handle after the former is broken,On the other hand, damaged internal organs are not easy to sell. The latter will not only cause the incompleteness of the squid carcass, but also result in the waste of squid meat. Second, the internal organs of squid include not only squid roe, but also the heart, gills, stomach, intestines, eggs and other substances of the squid. These substances are bonded together. Using a push knife cannot separate the squid roe from the internal organs of the squid, and it is easy to cut the squid roe during the process of pushing the knife, resulting in the waste of squid roe and the pollution of the squid. Third, the above-mentioned patent has a complex structure and cumbersome operation. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a method for bionic extraction of squid roe with a clever structure, simple operation, capable of completely taking out the squid roe, keeping the squid carcass intact, and high operation efficiency.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is:

[0005] A method for bionic extraction of squid roe, characterized in that it includes the following steps:

[0006] The first step: According to the size of the squid, loosen the connecting bolts and nuts on the tool horizontal limiting plate and the adjusting plate, adjust the front and rear positions of the tool horizontal limiting plate relative to the adjusting plate, then tighten the nuts to fix the position of the tool horizontal limiting plate. Place the squid on the support frame of the squid carrier, with the squid head facing backward and the squid tail facing forward. The carcass of the squid is embedded in the clamping groove of the fixture on the squid carrier, and the two tail fins of the squid are placed in front of the fixture. The two tail fins of the squid are limited by the fixture so that the squid cannot move backward. The squid head faces the direction of the roe extraction knife, and the head of the squid passes through the rear positioning groove of the support frame and droops in a natural vertical state.

[0007] The second step: In the initial state, the initial position of the roe extraction knife is behind the squid carrier, and the adjusting spring is in a compressed state. Then start the tool driving cylinder, and the telescopic rod of the tool driving cylinder extends. The tool mounting rack drives the tool moving rack, the tool plate and the roe extraction knife to move forward through the slideway. When the roe extraction knife is placed behind the squid carrier, it stops. At the same time, the tool plate is directly above the tool horizontal limiting plate. At this time, the rear end of the tool plate is connected to the tool moving rack through the guide post and the adjusting spring, and the front end of the tool plate is hinged to the tool moving rack. Because the adjusting spring is in a compressed state, the height of the rear end of the tool plate is lower than the height of the front end of the tool plate. The roe extraction knife is fixedly connected to the front end of the tool plate, so the height of the roe extraction knife is higher than the height of the rear end of the tool plate, and the knife head of the roe extraction knife is in a state of tilting forward and upward.

[0008] Step 3: Start the tool horizontal drive cylinder of the tool body horizontal support moving mechanism, the telescopic rod of the tool horizontal drive cylinder extends, driving the tool horizontal limit plate to move up to the lower end of the tool plate, against the tool plate, the adjustment spring is further compressed, the rear end of the tool plate rises, and is flush with the front end of the tool plate, so that the tool plate remains horizontal, and then the yellowing knife remains horizontal;

[0009] The fourth step: start the tool moving cylinder, the telescopic rod of the tool moving cylinder extends, and drives the tool moving frame to move forward under the guidance of the guide seat. The tool plate sticks to the tool horizontal limit plate and carries the yellow-picking knife horizontally from between the squid head and the squid carcass into the squid carcass. As the tool plate and the yellow-picking knife move forward, the tool plate moves forward and separates from the tool horizontal limit plate. Under the action of the rebound force of the adjusting spring, the rear end of the tool plate moves downward, so that the tool plate is tilted forward and upward. After the limit rod at the rear end of the tool plate descends, it abuts against the rear limit plate. The limit rod is limited, which limits the descending height of the rear end of the tool plate, and the upward inclination angle of the tool plate is fixed. The tool plate drives the front end of the yellow-picking knife to tilt upward to prevent the yellow-picking knife from breaking the squid yellow in the process of penetrating into the squid carcass. The yellow-picking knife continues to move forward until the front end of the yellow-picking knife reaches the front upper part of the end of the squid yellow, closes the tool moving cylinder, starts the tool horizontal drive cylinder, and the telescopic rod of the tool horizontal drive cylinder retracts, driving the tool horizontal limit plate to move downward and return to its original position.

[0010] Step 5: Start the horizontal driving cylinder of the yellow-picking knife of the picking angle adjustment mechanism, and the telescopic rod of the horizontal driving cylinder of the yellow-picking knife drives the horizontal pressing rod of the yellow-picking knife to move downward, and the horizontal pressing rod of the yellow-picking knife presses the yellow-picking knife downward, so that the front end of the yellow-picking knife changes from being tilted forward and upward to being tilted forward and downward, and the front end of the yellow-picking knife is pressed in front of the end of the squid yellow, and the squid yellow is embedded in the picking hole of the yellow-picking knife;

[0011] Step 6: Start the tool moving cylinder, and the yellowing knife moves backward with the squid yellow in the hole, leaving the squid carcass, and the front end of the yellowing knife is located behind the squid carrier;

[0012] Step 7: Start the horizontal driving cylinder of the yellow-picking knife of the picking angle adjustment mechanism, and the telescopic rod of the horizontal driving cylinder of the yellow-picking knife retracts, driving the horizontal pressure rod of the yellow-picking knife to move upward, and the lower end of the horizontal pressure rod of the yellow-picking knife is separated from the yellow-picking knife. The yellow-picking knife resumes the upward tilted state under the action of the adjustment spring on the tool plate, and the squid yellow in the picking hole tilts upward when the front end of the yellow-picking knife is lifted upward. At the same time, start the tool driving cylinder, and the telescopic rod of the tool driving cylinder retracts, driving the yellow-picking knife to move further backward and away from the squid carrier. The squid yellow in the picking hole of the yellow-picking knife slides out of the picking hole under the action of its own gravity, and naturally falls to the rear side of the squid carrier. The yellow-picking knife continues to move backward, and the yellow-picking knife is reset to remove the squid on the squid carrier.

[0013] Step 8: Repeat Steps 1 to 7 until all the squids have had their innards removed.

DETAILED DESCRIPTION OF THE INVENTION

[0025] The following will further describe in detail the specific implementation manners of the present invention in conjunction with the accompanying drawings.

[0026] A method for bionic yellow removal of squid, characterized by comprising the following steps:

[0027] The first step: As shown in the attached Figure 3 , according to the size of the squid, loosen the connecting bolts and nuts on the tool horizontal limiting plate 21 and the adjusting plate 27, adjust the front-back position of the tool horizontal limiting plate 21 relative to the adjusting plate 27, then tighten the nuts to fix the position of the tool horizontal limiting plate 21. Place the squid on the support frame of the squid carrier 2 with the squid head facing backward and the squid tail facing forward. The body of the squid is embedded in the clamping groove of the clamp on the squid carrier 2, and the two tail fins of the squid are placed in front of the clamp. The two tail fins of the squid are limited by the clamp so that the squid cannot move backward. The squid head faces the direction of the yellow removal knife 11, and the head of the squid passes through the positioning groove at the rear end of the support frame and hangs down in a natural vertical state;

[0028] The second step: In the initial state, the initial position of the yellow removal knife 11 is behind the squid carrier 2, and the adjusting spring 15 is in a compressed state. Then start the tool driving cylinder 5, and the telescopic rod of the tool driving cylinder 5 extends. The tool mounting rack 4 drives the tool moving rack 6, the tool plate 10 and the yellow removal knife 11 to move forward through the slideway 19. The yellow removal knife 11 stops when it is placed behind the squid carrier 2. At the same time, the tool plate 10 is directly above the tool horizontal limiting plate 21, as shown in the attached Figure 1 - attached Figure 5 . At this time, the rear end of the tool plate 10 is connected to the tool moving rack 6 through the guiding column 14 and the adjusting spring 15, and the front end of the tool plate 10 is hinged to the tool moving rack 6. Because the adjusting spring 15 is in a compressed state, the height of the rear end of the tool plate 10 is lower than the height of the front end of the tool plate 10. The yellow removal knife 11 is fixedly connected to the front end of the tool plate 10, so the height of the yellow removal knife 11 is higher than the height of the rear end of the tool plate 10, and the cutting head of the yellow removal knife 11 is in a state of tilting forward and upward;

[0029] The third step: Start the tool horizontal driving cylinder 22 of the tool body horizontal support moving mechanism 12. The telescopic rod of the tool horizontal driving cylinder 22 extends, driving the tool horizontal limiting plate 21 to move upward to the lower end of the tool plate 10 and abut against the tool plate 10. The adjusting spring 15 is further compressed, and the rear end of the tool plate 10 rises to be flush with the front end of the tool plate 10, so that the tool plate 10 is kept horizontal, and further the yellow removal knife 11 is kept horizontal;

[0030] Step 4: Start the tool moving cylinder 9, the telescopic rod of the tool moving cylinder 9 extends, driving the tool moving frame 6 to move forward under the guidance of the guide seat 8, and the tool plate 10 is attached to the tool horizontal limit plate 21 and carries the yellowing knife 11 horizontally into the squid carcass from between the squid head and the squid carcass. As the tool plate 10 and the yellowing knife 11 move forward, the tool plate 10 moves forward and separates from the tool horizontal limit plate 21. Under the action of the rebound force of the adjustment spring 15, the rear end of the tool plate 10 moves downward, so that the tool plate 10 is tilted forward and upward, and the limit rod 1 at the rear end of the tool plate 10 After the 6 is lowered, it abuts against the rear limit plate 17, and the limit rod 16 is limited, which limits the descending height of the rear end of the tool plate 10, so that the upward inclination angle of the tool plate 10 is fixed, and the tool plate 10 drives the front end of the yellow-picking knife 11 to be inclined upward, so as to prevent the yellow-picking knife 11 from breaking the squid yellow in the process of penetrating into the squid carcass. The yellow-picking knife 11 continues to move forward until the front end of the yellow-picking knife 11 reaches the front upper part of the end of the squid yellow, closes the tool moving cylinder 9, starts the tool horizontal driving cylinder 22, and the telescopic rod of the tool horizontal driving cylinder 22 is retracted, driving the tool horizontal limit plate 21 to move downward and return to its original position;

[0031] Step 5: Start the horizontal driving cylinder 25 of the picking angle adjustment mechanism 18, and the telescopic rod of the horizontal driving cylinder 25 drives the horizontal pressing rod 24 of the picking knife to move downward, and the horizontal pressing rod 24 presses the picking knife 11 downward, so that the front end of the picking knife 11 changes from being tilted forward and upward to being tilted forward and downward, and the front end of the picking knife 11 is pressed in front of the end of the squid yellow, and the squid yellow is embedded in the picking hole 23 of the picking knife 11;

[0032] Step 6: Start the tool moving cylinder 9, the telescopic rod of the tool moving cylinder 9 is retracted, and the tool moving frame 6 moves backward with the yellow-digging knife 11 and the squid yellow in the digging hole 23, leaving the squid carcass, and the front end of the yellow-digging knife 11 is located behind the squid carrier 2;

[0033] The seventh step: start the yellow knife horizontal driving cylinder 25 of the picking angle adjustment mechanism 18, the telescopic rod of the yellow knife horizontal driving cylinder 25 retracts, driving the yellow knife horizontal pressure rod 24 to move upward, and the lower end of the yellow knife horizontal pressure rod 24 is separated from the yellow knife 11. The yellow knife 11 resumes the upward tilted state under the action of the adjustment spring 15 on the tool plate 10, and the squid yellow in the picking hole 23 is tilted upward when the front end of the yellow knife 11 is lifted upward. At the same time, start the tool driving cylinder 5, the telescopic rod of the tool driving cylinder 5 retracts, driving the yellow knife 11 to move further backward and away from the squid carrier 2. The squid yellow in the picking hole 23 of the yellow knife 11 slides from the picking hole 23 under the action of its own gravity, and naturally falls to the rear side of the squid carrier 2.

A control system can be arranged on the yellow extraction frame 1 of the present invention, such as a PLC control system. The tool driving cylinder 5, the tool moving cylinder 9, and the tool horizontal driving cylinder 22 are all connected to the control system and controlled by the control system. The structure of the present invention is simple. The squid is limited and fixed by the squid carrier 2. The yellow extraction knife 11 extends forward into the squid body to reach the front of the end of the squid yellow. Then, the angle of the yellow extraction knife 11 is adjusted so that the yellow extraction knife 11 moves downward and then backward to take out the squid yellow. The squid yellow is located above other internal organs in the squid body. By adjusting the angle of the yellow extraction knife 11, the squid yellow can be separated from other internal organs in the squid body and the squid yellow can be taken out. At the same time, the downward inclination angle of the yellow extraction knife 11 can also be adjusted by the extraction angle adjustment mechanism 18 to take out the entire squid internal organs. In addition, the present invention limits and fixes the squid by the squid carrier 2, so that the squid body always adheres to the squid carrier 2, supports and clamps the squid, enabling the yellow extraction knife 11 to quickly and well take out the squid yellow. The present invention adopts a method similar to manual extraction. By continuously adjusting the angle of the yellow extraction knife 11, the squid yellow can be completely taken out. When the entire internal organs need to be taken out, the entire squid internal organs can also be completely taken out by adjusting the angle of the yellow extraction knife 11, which can be set according to requirements. Compared with manual operation, the present invention has higher working efficiency, is fast and accurate in extraction. Compared with the existing method of using a push knife to cut off the connection between the squid internal organs and the squid body, it can well maintain the integrity of the squid yellow, squid internal organs and squid body, and improve the sales volume of the squid yellow and squid body.

[0038] Due to the adoption of the above structure, the present invention has the advantages of ingenious structure, simple operation, being able to take out the squid yellow completely, keeping the squid carcass intact, and high operation efficiency.
