Description

Technical Field

[0001] The invention relates to the technical field of aquatic product processing, in particular to a conveying device for aquatic product processing. Background Art

[0002] Aquatic products refer to various organisms caught or farmed from oceans, lakes, rivers and other waters, including fish, shrimps, crabs, shellfish, algae, etc. They are rich in high-quality protein, vitamins and minerals, and are one of the important food sources for humans.

[0003] After the fish are caught and brought ashore, they need to be initially processed, such as cold packaging, to ensure the freshness of the fish, facilitate the transportation of cold fresh fish to inland or other more distant areas, and avoid the problem of fish spoilage during transportation. Therefore, vacuum packaging of cold fresh fish is an important process in fish processing. Vacuum packaging can remove oxygen in the packaging bag, inhibit the growth of aerobic bacteria and microorganisms, and thus extend the shelf life of the fish.

[0004] At present, when vacuum packaging of fresh fish, it is necessary to arrange the unsealed bagged fresh fish neatly and evenly, press the mouth and convey it to the vacuum packaging machine.

DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] like Figure 1 As shown, a conveying device for processing aquatic products includes: a frame 1, the frame 1 is U-shaped, and the opening of the frame 1 faces downward, two front-to-back symmetrical L-shaped frames 2 are arranged on the right side of the frame 1, and a conveying device is arranged between the two L-shaped frames 2, and the conveying device includes an existing conveying chain plate 3, and the conveying chain plate 3 is driven by an external motor (not shown in the figure) to perform a conveying operation. An adjustment mechanism 4 for adjusting the position of fresh fish is commonly arranged on the frame 1 and the L-shaped frame 2, and the adjustment mechanism 4 includes a primary unit 5 arranged on the frame 1, a secondary unit 6 arranged on the L-shaped frame 2, and a driving unit 7 for driving the adjustment action.

[0033] like Figure 1 and Figure 2 As shown, the primary unit 5 includes an adjustment plate 50, and a plurality of plate groups equidistantly arranged from front to back are slidably arranged in front of and behind the lower end surface of the horizontal section of the frame 1, and the plate group includes two adjustment plates 50 distributed in front and back, and the lower end surface of the adjustment plate 50 is higher than the upper end surface of the conveying chain plate 3.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the secondary unit 6 includes a horizontal frame 60, and the horizontal frame 60 is fixedly arranged between the horizontal sections of the two L-shaped frames 2. Two front-to-back symmetrical vertical columns 600 are penetrated on the horizontal frame 60 for sliding up and down. A downward plate 601 is fixedly arranged on the lower end surfaces of the two vertical columns 600. An adjustment plate 2 602 corresponding to the plate group is arranged on the lower side of the downward plate 601. A plurality of groups of equidistantly arranged block groups are fixedly arranged on the conveying chain plate 3, and the block group includes a plurality of fixed blocks 603 which are equidistantly arranged from front to back and correspond to the plate groups one by one. The upper fixed block 603 is taken as an example for explanation, and the right end surface of the fixed block 603 is hinged with two front-to-back distributed support plates 604.

[0035] During operation, the packaging bags containing fresh fish are placed on the conveyor chain plate 3 in an arrangement from front to back, with the opening of the packaging bags facing the right and the packaging bags located on the right side of the corresponding fixed block 603. Then the external motor works to make the conveyor chain plate 3 drive the packaging bags to move right synchronously for transportation. In the process of moving the packaging bags from left to right, the positions of multiple packaging bags in the same column and the positions of the fish therein are adjusted by the adjustment mechanism 4. It should be noted that an existing external vacuum packaging machine (not shown in the figure) is arranged on the right side of the conveyor chain plate 3, and the adjusted column of bagged fresh fish is moved to the vacuum packaging machine for vacuum packaging.

[0036] In the process of the bagged chilled fresh fish moving from left to right, the driving unit 7 works to make the two adjustment plates 1 50 in the same plate group in the primary unit 5 approach each other, so that the corresponding bagged chilled fresh fish in each plate group is placed in a state of facing from left to right, and a distance is kept between two adjacent bagged chilled fresh fish to avoid affecting the subsequent sealing operation. After completing the primary adjustment of the bagged chilled fresh fish, the bagged chilled fresh fish moves to the secondary unit 6, and the driving unit 7 works to make the adjustment plate 2 602 in the secondary unit 6 move down and The corresponding bagged chilled fresh fish is pressed down, and the position of the chilled fresh fish in the bag is adjusted so that the chilled fresh fish moves to the left relative to the packaging bag to the left end of the packaging bag. Secondly, the propping plate 604 is driven to move rightward by the conveying chain plate 3, so that the propping plate 604 is used as the placement reference of the bagged chilled fresh fish. That is, in the process of adjusting the position of the chilled fresh fish, the bagged chilled fresh fish is moved to be close to the propping plate 604, so as to facilitate the adjustment of the distance between the bagged chilled fresh fish and the right end opening to be consistent, thereby facilitating the subsequent sealing operation of the bagged chilled fresh fish in the same row.

[0037] like Figure 1 and Figure 2 As shown, the primary unit 5 also includes an L-shaped bar 51, and the left end surface of the horizontal section of the frame 1 is fixedly provided with an L-shaped bar 51 corresponding to the adjustment plate 1 50, and a connecting plate 510 located on the left side of the adjustment plate 1 50 is fixedly provided on the L-shaped bar 51, and a guide plate 511 is fixedly provided on the left end surface of the connecting plate 510. Taking the frontmost guide plate 511 as an example for explanation, the frontmost guide plate 511 is tilted backward from left to right, and the tilt directions of the two adjacent guide plates 511 are opposite.

[0038] like Figure 1 and Figure 2 As shown, the driving unit 7 includes a threaded rod 70, and a threaded rod 70 with an axis extending from front to back and passing through all the adjustment plates 50 is rotatably arranged between the two vertical sections of the frame 1. The threaded rod 70 is provided with a threaded section corresponding to the adjustment plate 50 and is threadedly matched with the adjustment plate 50. The spiral directions of the threaded sections corresponding to the two adjustment plates 50 in the same plate group are opposite, and a volute spring 700 is fixedly arranged between the threaded rod 70 and the vertical section of the frame 1.

[0039] like Figure 1 and Figure 2 As shown, the driving unit 7 also includes a driving wheel group. The front vertical section of the frame 1 and the vertical section of the front L-shaped frame 2 are both provided with driving wheel groups. The driving wheel group includes a transmission shaft 71. Taking the driving wheel group on the frame 1 as an example for explanation, a transmission shaft 71 with an axis extending from front to rear is installed and rotated on the front vertical section of the frame 1. A transmission gear 710 located on the rear side of the vertical section of the frame 1 is fixedly sleeved on the transmission shaft 71. The threaded rod 70 is connected to the transmission shaft 71 on the frame 1 through a sprocket chain transmission.

[0040] like Figure 1 and Figure 2 As shown, the driving unit 7 also includes a driving rack 72 , and the front end surface of the conveying chain plate 3 is equidistantly provided with driving racks 72 along its circumference, which are the same number as the block groups, and the driving racks 72 are meshed with the transmission gear 710 .

[0041] During operation, when the bagged chilled fresh fish is placed on the conveying chain plate 3 in a specified placement state and as the conveying chain plate 3 gradually moves to the right, the conveying chain plate 3 drives the driving rack 72 to move synchronously. It should be noted that when placing the bagged chilled fresh fish, it is necessary to place it in a position opposite to the front and rear of the corresponding driving rack 72.

[0042] As the bagged cold fresh fish continues to move, the two corresponding guide plates 511 in each plate group guide the direction of the bagged cold fresh fish, so that the bagged cold fresh fish are all placed horizontally, avoiding the problem of the bagged cold fresh fish being unable to be sealed due to a large deviation in direction during transportation. When the bagged cold fresh fish continues to move to be opposite to the front and back of the adjustment plate 1 50, the corresponding driving rack 72 and the transmission gear 710 on the frame 1 are meshed with each other, so that the transmission gear 710 drives the transmission shaft 71 to rotate synchronously, and the transmission of the sprocket chain causes the screw to rotate. The threaded rods 70 rotate synchronously, and through the threaded cooperation between all the adjustment plates 50 and the threaded rods 70, two adjustment plates 50 in the same plate group are brought close to each other, squeezing the bagged fresh fish therebetween, and adjusting the front and rear positions of the bagged fresh fish again, so that multiple bagged fresh fish in the same row are arranged equidistantly from front to back, thereby avoiding the sealing effect being affected by the bag openings of two adjacent bagged fresh fish being too close to each other, and avoiding the bag openings of two adjacent bagged fresh fish being in contact with each other, affecting the subsequent vacuuming operation, and resulting in poor sealing effect of the bagged fresh fish.

[0043] In the above process, the volute spring 700 is deformed. When the corresponding drive rack 72 continues to move right and is offset from the transmission gear 710, the elastic force generated by the deformation of the volute spring 700 causes the threaded rod 70 to reverse. The threaded cooperation between the threaded rod 70 and the adjustment plate 50 causes all the adjustment plates 50 to reset, making it easier for the subsequent drive rack 72 to cooperate with the transmission gear 710 and adjust the front and rear positions of another batch of bagged fresh fish.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown, the secondary unit 6 also includes a connecting rod 605, and the lower end surface of the lower moving plate 601 slides up and down and penetrates a connecting rod 605 with a vertical axis and corresponding to the adjustment plate 602. The adjustment plate 602 is fixedly arranged on the lower end surface of the connecting rod 605, and a spring 606 mounted on the connecting rod 605 is fixedly arranged between the adjustment plate 602 and the lower moving plate 601. The lower end surface of the adjustment plate 602 is provided with an arc groove 607 with a larger cross-section on the left and a smaller cross-section on the right.

[0045] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the secondary unit 6 also includes a penetration block 61, and the vertical section of the L-shaped frame 2 is slidably provided with a penetration block 61 up and down, and the penetration block 61 penetrates the L-shaped frame 2 front and back, and a spring 610 for resetting is fixedly provided between the penetration block 61 and the L-shaped frame 2, and the opposite surfaces of the two penetration blocks 61 are fixedly provided with a transverse plate 611, and a lower pressure plate 612 is slidably provided between the two transverse plates 611 left and right, and a fixed plate 613 cooperating with the lower pressure plate 612 is fixedly provided on the conveying chain plate 3, and the number of the fixed plates 613 is the same as the number of the driving racks 72, and a lower pressure strip 614 corresponding to the plate group is fixedly provided on the lower end surface of the lower pressure plate 612, and a bar group located directly below the lower pressure strip 614 is fixedly provided on the upper end surface of the fixed plate 613, and the bar group includes two fixed bars 615 distributed left and right, and the cross-sections of the lower pressure strip 614 and the fixed bar 615 are both semicircular and made of rubber material.

[0046] like Figure 2 As shown, the fixed block 603 is fixedly provided with a horizontal rod 616 with an axis extending from left to right on the end face away from the corresponding support plate 604, and a U-shaped push block 617 is slidably sleeved on the horizontal rod 616, and the U-shaped opening of the U-shaped push block 617 faces the corresponding support plate 604, and a spring 618 sleeved on the horizontal rod 616 is fixedly provided between the U-shaped push block 617 and the fixed block 603.

[0047] like Figure 1 , Figure 4 and Figure 6As shown, the secondary unit 6 also includes a guide column 62, and two guide columns 62 with front-to-back symmetry and vertical axes are fixedly arranged on the upper end surface of the fixed plate 613. A truncated cone groove 620 corresponding to the guide column 62 and smaller at the top and larger at the bottom is penetrated and opened on the lower pressure plate 612. A limiting cylinder 621 located directly above the truncated cone groove 620 and cooperating with the guide column 62 is fixedly arranged on the upper end surface of the lower pressure plate 612.

[0048] It should be noted that the number of columns of the fixed blocks 603, the number of the driving racks 72 and the fixed bars 615 are the same, and the three work together to adjust the bagged cold fresh fish in the same column. In the process of placing the bagged cold fresh fish, the bagged cold fresh fish is placed on the conveyor chain plate 3 while the open end of the bagged cold fresh fish is placed above the fixed bar 615.

[0049] During operation, the bagged cold fresh fish moves out of the primary unit 5 and gradually enters the secondary unit 6. At this time, a row of bagged cold fresh fish is arranged equidistantly from front to back and the fish are placed in a left-right direction. The conveying chain plate 3 drives the driving rack 72 corresponding to the row of bagged cold fresh fish to move synchronously. The two penetration blocks 61 move downward through the cooperation of the driving rack 72 and the driving wheel group. The spring 1 610 is compressed, and the two penetration blocks 61 drive the transverse plate 611 and the lower pressure plate 612 to move downward synchronously. During the downward movement of the lower pressure plate 612, the driving unit 7 is used to drive the lower plate 601 to drive all the The adjustment plate 602 moves downward synchronously, and as it continues to move, the corresponding fixed plate 613 moves to just below the lower pressing plate 612. As the lower pressing plate 612 continues to move downward, the arc-shaped surface of the frustum groove 620 on the lower pressing plate 612 guides the guide column 62 to penetrate the lower pressing plate 612, and finally the guide column 62 penetrates into the corresponding limiting cylinder 621. At the same time, the lower plate 601 drives all the adjustment plates 602 to move downward synchronously to contact the right upper end of the corresponding bagged fresh fish, so that the right end part of the bagged fresh fish is located in the arc-shaped groove 607 on the adjustment plate 602.

[0050] As the driving rack 72 continues to move, the lower pressing plate 612 drives the lower pressing strip 614 thereon to press the bag opening of the bagged fresh fish down onto the fixing strip 615, and causes the lower pressing strip 614 and the fixing strip 615 to deform. The deformation of the two strengthens the compression and limiting effect on the bag opening of the bagged fresh fish, ensuring that the bag opening of the bagged fresh fish will not fall off during the subsequent movement. Afterwards, the conveying chain plate 3 drives the fixing plate 613, the lower pressing plate 612 and the bagged fresh fish to move right synchronously, but because the adjustment plate 2 602 remains stationary, Therefore, during the rightward movement of the bagged fresh fish, the inner wall of the arc groove 607 of the adjusting plate 2 602 limits the movement of the fresh fish in the packaging bag, and the packaging bag moves right synchronously with the lower pressing plate 612 and the fixing plate 613, thereby indirectly causing the fresh fish to move leftward relative to the packaging bag to an area close to the tail of the bag, thereby avoiding the problem of affecting the sealing operation due to the position of the fresh fish being too close to the seal in the subsequent sealing process. Secondly, in this process, the spring 2 606 is compressed and deformed, so that the adjusting plate 2 602 exerts an elastic limiting effect on the fish.

[0051] As the driving rack 72 continues to move, the driving unit 7 stops driving the lower pressure plate 612 in the secondary unit 6 to move downward, and the elastic force generated by the deformation reset of the spring 1 610 causes the lower pressure plate 612 to move up a certain distance, so the lower moving plate 601 also moves up a certain distance, and the spring 2 606 remains in a compressed state (but the degree of deformation is reduced, and thus the pressure acting on the adjustment plate 2 602 is reduced). At this time, the lower pressure plate 612 still maintains a certain contact with the packaging bag under the action of the spring 4 742, so at this time, the lower pressure plate 612 and the fixed plate 613 press the packaging bag tightly. The effect is weakened to prevent the packaging bag from being subjected to excessive tension, causing the chilled fish in the packaging bag to directly pass over the adjustment plate 2 602; as the conveyor chain plate 3 continues to move, the packaging bag continues to move right, but at this time the adjustment plate 2 602 hinders the right movement of the chilled fish, so only the packaging bag moves to the right, and the chilled fish moves to the left relative to the packaging bag. The positions of the chilled fish in the same row are adjusted by multiple adjustment plates 2 602, so that the left ends of the bagged chilled fish in the same row are aligned with the two support plates 604 on the corresponding fixed block 603 as the reference, which is convenient for subsequent vacuuming and sealing operations.

[0052] It should be noted that after placing the bagged chilled fresh fish, the bagged chilled fresh fish is pressed against the corresponding two opening plates 604. Through the cooperation of spring three 618 and U-shaped push block 617, the corresponding two opening plates 604 in this state always maintain a V-shaped state with the opening facing the right side. The V-shaped area jointly formed by the corresponding two opening plates 604 is convenient for controlling the position of the bagged chilled fresh fish during the subsequent movement to avoid its tilting. At the same time, the V-shaped area also serves as the left reference for the secondary adjustment operation in the secondary unit 6.

[0053] like Figure 1 and Figure 4As shown, the driving unit 7 also includes an extension plate 73, and the left end face of the vertical section of the front L-shaped frame 2 is fixedly provided with the extension plate 73, and the driving wheel group corresponding to the L-shaped frame 2 is arranged on the extension plate 73, and the front end face of the vertical section of the L-shaped frame 2 is rotatably provided with a driving gear 730 located on the front side of the L-shaped frame 2 through a rotating shaft, and a tooth plate 731 located on the right side of the driving gear 730 and meshing with the driving gear 730 is fixedly provided on the through block 61, and the transmission shaft 71 is connected to the rotating shaft through a sprocket chain transmission.

[0054] like Figure 1 , Figure 4 and Figure 6 As shown, the driving unit 7 also includes a square block 74, and two square blocks 74 distributed front and back are fixedly provided at the right end of the lower plate 601, a connecting column 740 is fixedly provided on the square block 74, a sliding block 741 is slidably sleeved up and down on the connecting column 740, a spring four 742 sleeved on the connecting column 740 is fixedly provided between the sliding block 741 and the square block 74, a mounting column 743 with an axis extending from left to right is fixedly provided on the right end face of the sliding block 741, a side plate 744 fixedly connected to the lower pressure plate 612 is slidably sleeved on the mounting column 743, and a spring five 745 sleeved on the mounting column 743 is fixedly provided between the mounting column 743 and the side plate 744 via a mounting circular plate.

[0055] During operation, the conveying chain plate 3 drives the driving rack 72 to continue to move right after passing the primary unit 5, and the driving rack 72 contacts the transmission gear 710 on the extension plate 73 and starts to mesh, so that the transmission gear 710 and the transmission shaft 71 rotate synchronously, and the transmission shaft 71 drives the rotating shaft and the driving gear 730 to rotate synchronously through the sprocket chain transmission, and the meshing between the driving gear 730 and the tooth plate 731 makes the tooth plate 731 drive the through block 61 and the transverse plate 611 to move downward synchronously, and the transverse plate 611 drives the lower pressure plate 612 to move downward synchronously, and the lower pressure plate 612 drives the sliding block 741 to move downward synchronously through the two side plates 744, and the sliding block 741 drives the lower plate 601 and all the adjustment plates 602 to move downward synchronously through the spring four 742.

[0056] It should be noted that, in the initial state, the lower end surface of the adjustment plate 602 is lower than the lower end surface of the lower pressure plate 612. The adjustment plate 602 continues to move downward and stops moving after contacting the bagged fresh fish. At this time, the bag mouth of the bagged fresh fish is located between the lower pressure plate 612 and the fixed plate 613. Then, as the driving rack 72 and the driving gear 730 continue to mesh, the lower pressure plate 612 continues to move downward to press the bag mouth onto the fixed plate 613. Then, as the conveying chain plate 3 continues to move, the fixed plate 613 drives the lower pressure plate 612 to move right synchronously through the cooperation between the guide column 62 and the limiting cylinder 621, and the side plate 744 moves synchronously, and the spring five 745 is compressed. After completing the secondary adjustment operation, when the lower pressure plate 612 disengages from the corresponding fixed plate 613, the elastic force generated by the deformation of the spring five 745 causes the lower pressure plate 612 to move left and reset.
