Description

Technical Field

[0001] This invention relates to the field of fish fillet processing technology, and more specifically, to an automatic feeding platform conveying system for sorting black carp fillets. Background Technology

[0002] In the aquatic product processing industry, snakehead fish fillets are widely welcomed by the market due to their high protein and low fat content. The current snakehead fish fillet processing process first involves cutting the snakehead fish into fillets, then weighing and sorting the fillets, deboning the sorted fillets, rinsing the deboned fillets, and then sending them to the slicing station to slice them into thin snakehead fish fillets.

[0003] However, in the above-mentioned process of processing blackfish fillets, the deboned fish fillets slide down the guide plate into the collection tray on the conveyor structure. This process easily causes the fish fillets to bend and pile up. At the same time, the subsequent rinsing will also cause the fish fillets to bend and pile up, making it impossible to ensure that the fish fillets are laid flat in the collection tray. The fish fillets need to be rearranged for subsequent slicing, which reduces the processing efficiency of blackfish fillets. In addition, the long-term bending and piling of the fish fillets during the conveying process damages the shape of the fish fillets, making it difficult to slice them and reducing the quality of the sliced ​​fillets. Summary of the Invention

This system involves placing deboned fish fillets onto a weighing plate for weighing and sorting. The weighing plate is rotated, causing the fish fillets to slide onto corresponding support units. The fillets are laid flat on the moving support units. Through the coordinated operation of the support units and guide units, the flat feeding of the fish fillets and the closure of the sliding cover and the storage tray are completed.

The fish fillets are laid flat on the moving support part 9. Through the linkage between the support part 9 and the guide part 7, the flat feeding of the fish fillets and the closing of the sliding cover 12 and the storage tray 11 are completed. This ensures that the fish fillets remain flat during transportation, eliminating the need for subsequent repositioning of the fish fillets, simplifying the process, improving work efficiency, and ensuring the quality of subsequent slicing.

[0036] Example 2, please refer to Figure 1-14 This second embodiment is an improvement on the first embodiment as follows: Specifically, the inner wall of the fixed frame 4 is provided with a shaft hole 16; a weighing device 21 is fixed on the surface of the weighing plate 5; a rotating shaft 17 that rotatably engages with the corresponding shaft hole 16 is fixed on both opposite sides of the weighing plate 5; a first motor 18 is fixedly installed on the side of the fixed frame 4; the output end of the first motor 18 is fixedly connected to the end of a rotating shaft 17; an L-shaped bone removal table 19 is fixed on the side of the water tank 2; a controller 20 is installed on the side of the L-shaped bone removal table 19; the output end of the controller 20 is electrically connected to the first motor 18, and its input end is electrically connected to the weighing device 21.

[0037] A support plate 22 is symmetrically fixed to the bottom of the pool 2; a side plate 56 is fixed between the two support plates 22; a connecting shaft is rotatably installed through the side of each support plate 22 and L-shaped plate 3; a pulley 23 is fixed to the end of the connecting shaft; a conveyor belt 6 is driven between the corresponding two pulleys 23; a second motor 24 and a third motor 25, which are electrically connected to the output of the controller 20, are respectively installed on the side of the two L-shaped plates 3; the outputs of the second motor 24 and the third motor 25 are fixedly connected to the ends of the corresponding connecting shafts.

[0038] The U-shaped plate 10 has a sliding hole 26 on its side that slides with the lug 8; the U-shaped plate 10 has a positioning hole 27 on its surface that communicates with the sliding hole 26; the lug 8 has a screw hole on its outer wall; and a bolt that is screwed into the screw hole is slidably installed inside the positioning hole 27.

[0039] The ear rod 8 has an annular groove 28 on its side; the storage tray 11 has a first half connecting tube 29 fixed on its side; the first half connecting tube 29 has a second half connecting tube 30 coaxial with it fixed by fastening bolts; the inner walls of the first half connecting tube 29 and the second half connecting tube 30 are both fixed with a semi-annular rail 31 that rotates with the annular groove 28; the outer walls of the first half connecting tube 29 and the second half connecting tube 30 are both symmetrically fixed with ear seats 32.

[0040] Working principle of this embodiment two: By sliding the sliding hole 26 on the U-shaped plate 10 into the corresponding ear rod 8, and fixing the U-shaped plate 10 and the ear rod 8 together with bolts, the fixed connection between each group of U-shaped plates 10 and the corresponding ear rod 8 is completed in sequence; the first half connecting tube 29 and the second half connecting tube 30 are fixed together with fastening bolts, and the ear rod 8 is placed in the first half connecting tube 29 and the second half connecting tube 30. After the fixed connection is completed, the first half connecting tube 29 and the second half connecting tube 30 can rotate freely around the ear rod 8; in summary, the bearing part 9 is detachably installed on the corresponding ear rod 8, which facilitates the assembly and disassembly of the bearing part 9.

[0041] like Figure 1 as well as Figure 2 As shown, the deboned fish fillets are laid flat on the weighing plate 5 and the weighing device 21. The weighing device 21 weighs the fillets and transmits the signal to the controller 20. When the weight of the fish fillets is not higher than the set value, the controller 20 controls the first motor 18 to rotate counterclockwise, causing the weighing plate 5 to rotate counterclockwise by a certain angle. At the same time, it controls the third motor 25 to rotate counterclockwise, causing the corresponding bearing part 9 to rotate counterclockwise. The fish fillets slide off the surface of the weighing plate 5 and onto the corresponding movable storage tray 11, completing the laying. When the weight of the fish fillets is higher than the set value, the controller 20 controls the first motor 18 to rotate clockwise, causing the weighing plate 5 to rotate clockwise by a certain angle. At the same time, it controls the second motor 24 to rotate clockwise, causing the fish fillets to slide off the surface of the weighing plate 5 and onto the corresponding movable storage tray 11, completing the laying and completing the weighing and sorting of the fish fillets.

[0042] Example 3, please refer to Figure 1-14This third embodiment is an improvement on the second embodiment as follows: Specifically, the surface of the storage tray 11 is symmetrically provided with sliding grooves 33; the inner walls of the sliding grooves 33 are symmetrically provided with limiting grooves 34 on both sides; baffles 35 are symmetrically fixed on the surface of the storage tray 11; the sliding cover 12 includes a U-shaped cover 36 that slides with the sliding grooves 33; the side of the U-shaped cover 36 is symmetrically fixed with limiting rails 37 that slide with the corresponding limiting grooves 34; a connecting plate 38 is fixedly fixed at the top inside the U-shaped cover 36; a return spring 39 is fixedly connected between the connecting plate 38 and the corresponding baffle 35.

[0043] A rotating rod 40 is fixed on the other opposite side of the connecting plate 38; the outer wall of the rotating rod 40 is provided with a straight guide groove 41 and a spiral groove 42 that are interconnected and adapted to the ball head 15; a guide ball 43 is fixed at the end of the rotating rod 40.

[0044] The guide section 7 includes two sets of vertical plates 44 fixedly installed on the surface of the base 1; an annular guide rail 45 adapted to the conveyor belt 6 is fixed between the two vertical plates 44; a convex rail 46 adapted to the guide ball 43 is fixed on the side of the annular guide rail 45; the convex rail 46 includes a first inclined guide rail 47, a first straight guide rail 48, a second inclined guide rail 49, a third inclined guide rail 50, a second straight guide rail 51 and a fourth inclined guide rail 52 connected in sequence.

[0045] The fixed frame 4 has nozzle seats 53 fixed on both sides; a number of nozzles 54 are evenly connected on the bottom surface of the nozzle seat 53; a water supply pipe 55 is connected on the bottom surface of the nozzle seat 53; a solenoid valve that is electrically connected to the output end of the controller 20 is installed on the water supply pipe 55.

[0046] Working principle of this embodiment three: When the weight of the fish fillet is not higher than the set value, the controller 20 controls the first motor 18 to rotate counterclockwise, causing the weighing plate 5 to rotate counterclockwise by a certain angle. At the same time, it controls the third motor 25 to rotate counterclockwise, causing the corresponding bearing part 9 to rotate counterclockwise. The fish fillet slides from the surface of the weighing plate 5 onto the corresponding moving storage tray 11, completing the flat laying. At this time, the U-shaped cover 36 separates from the corresponding storage tray 11, and the corresponding guide ball 43 abuts against the side of the annular guide rail 45 under the elastic force of the return spring 39. The bearing part 9 continues to be driven by the conveyor belt 6.

[0047] When the guide ball 43 slides from the annular guide rail 45 into the first inclined guide rail 47, the guide ball 43 is squeezed and drives the U-shaped cover 36 to slide towards the storage tray 11. The return spring 39 is compressed until the U-shaped cover 36 completely covers the storage tray 11, completing the closing of the storage tray 11 and the U-shaped cover 36. As the guide ball 43 continues to slide on the first inclined guide rail 47, it drives the U-shaped cover 36 to continue sliding towards the U-shaped plate 10. The U-shaped cover 36 remains closed on the storage tray 11. During this process, the ball head 15 slides along the straight guide groove 41, and the U-shaped cover 36 only slides in the horizontal plane.

[0048] When the guide ball 43 slides on the first straight guide rail 48, the bearing part 9 that completes the sealing moves to directly below the nozzle seat 53. When the guide ball 43 just slides onto the second inclined guide rail 49, the ball head 15 just slides from the straight guide groove 41 into the spiral groove 42. During the process of the guide ball 43 sliding on the second inclined guide rail 49, the spiral groove 42, guided by the ball head 15, drives the rotating rod 40 to rotate, thereby driving the U-shaped cover 36 and the storage tray 11 to rotate synchronously, so as to realize the rotation and cleaning of the fish fillets laid flat on the storage tray 11, thereby improving the cleaning effect.

[0049] When the guide ball 43 slides from the second inclined guide rail 49 to the third inclined guide rail 50, the bearing part 9 disengages from the nozzle seat 53. Under the elastic reset action of the return spring 39, the spiral groove 42, guided by the ball head 15, drives the rotating rod 40 to rotate in the opposite direction, thereby driving the U-shaped cover 36 and the storage tray 11 to rotate in the opposite direction synchronously, thus realizing the rotation and centrifugal dehydration of the fish fillets laid flat on the storage tray 11.

[0050] When the guide ball 43 slides from the third inclined guide rail 50 to the second straight guide groove 51, the ball head 15 slides from the spiral groove 42 into the straight guide groove 41, causing the bearing part 9 in the sealed state to rotate to remain parallel to the horizontal plane.

[0051] As the guide ball 43 slides on the fourth inclined guide rail 52, under the reset action of the reset spring 39, it drives the U-shaped cover 36 to slide along the surface of the storage tray 11 away from the U-shaped plate 10 until the U-shaped cover 36 separates from the storage tray 11. At this time, the cleaned and dehydrated fish fillets can be taken out for slicing.
