Description

Technical Field

[0001] This utility model relates to the field of aquatic product processing equipment technology, and in particular to a swaying structure and a dormant fish line-turning device. Background Technology

[0002] Currently, as consumers demand higher quality seafood products, the demand for high-value fish such as large yellow croaker, tuna, and salmon has increased significantly. These fish are often expensive and have extremely stringent requirements for production, transportation, and storage. Therefore, more sophisticated and efficient production lines are needed to ensure the quality and production efficiency of seafood products.

[0003] In existing technologies, dormant fish must pass through multiple diversion channels before entering the freezing conveyor line from the dormant fish conveyor line. Only one dormant fish is allowed to pass through each diversion channel at a time, thus separating multiple dormant fish and preventing them from freezing and sticking together after entering the freezing conveyor line, which would be detrimental to storage, transportation, and sales. However, in existing production lines, the entrance size of the diversion channels that only allow one dormant fish to pass at a time is small. When there are many dormant fish or the angle of the fish is not ideal, the dormant fish can clog the entrance of the diversion channel, blocking the transport of dormant fish and resulting in low production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that when there are a large number of dormant fish or the angle of the fish body is not good, the dormant fish block the entrance of the diversion channel, blocking the transport of dormant fish, resulting in low production efficiency of the production line.

[0025] Preferably, the third platform is provided with multiple vertically arranged diversion plates, each diversion plate extending along the direction of transporting the dormant fish, and the multiple diversion plates are arranged at intervals along the direction perpendicular to the direction of transporting the dormant fish, with the interval between each diversion plate being a diversion channel.

[0026] Preferably, the diverter plate includes a first segment and a second segment connected sequentially along the direction of transporting the dormant fish. Both sides of the first segment are inclined outward along the direction of transporting the dormant fish, and the end faces of the first segment and the second segment that are connected to each other have the same dimensions.

The vision sensor is used to monitor whether the hibernating fish enters the working area of ​​the fish pushing structure. The controller is electrically connected to the vision sensor, the position sensor, the first drive unit, the second drive unit, and the third drive unit.

[0034] Compared with the prior art, the swaying structure and dormant fish line-switching device of this utility model have the following advantages:

[0035] In this embodiment of the swaying structure, a first platform is horizontally slidably mounted on a fixed frame. One end of a first transmission rod is hinged to the first platform, and the other end of the first transmission rod is hinged to one end of a second transmission rod. The other end of the second transmission rod is connected to a first driving member for anti-rotation. In use, the first driving member drives the second transmission rod to rotate in the horizontal plane, and the second transmission rod drives the first transmission rod to oscillate, causing the end of the first transmission rod connected to the first platform to move closer to / away from the first driving member. This, in turn, drives the first platform to perform horizontal reciprocating motion, thereby swaying the dormant fish on the first platform and adjusting the angle of the dormant fish's body to avoid blocking the conveyor channel on the production line.

[0036] The dormant fish transfer device of this utility model includes a second platform, a swaying structure, and a third platform arranged sequentially along the dormant fish conveying direction. The second platform is located at the front end of the dormant fish conveying direction, the outlet of the third platform is connected to the freezing conveyor line, and the swaying structure is located between the second and third platforms. To meet the conveying power requirements of the dormant fish on the first and third platforms, both the first and third platforms are inclined downwards along the dormant fish conveying direction, and the platform surfaces of the first and third platforms are coplanar, so that after the dormant fish enters the first platform from the second platform, it can reliably slide forward through the first and third platforms under gravity. In use, after the dormant fish is conveyed to the working area of ​​the pusher structure, the pusher structure conveys the dormant fish to the first platform of the swaying structure. The dormant fish slides along the first platform to the third platform and then enters the freezing conveyor line sequentially through the diversion channel. The freezing conveyor line continues to convey the dormant fish to the freezing tunnel for freezing treatment. To prevent the dormant fish from blocking the entrance of the diversion channel, the first driving component of the swaying structure drives the first platform to reciprocate along the direction perpendicular to the conveying direction of the dormant fish via the first transmission rod and the second transmission rod. This sways the dormant fish on the first platform, making it less likely for the dormant fish to stick to the first platform. This adjusts the angle of the dormant fish's body, allowing the dormant fish to pass through the diversion channel in sequence, thus avoiding blockage of the conveying channel on the production line.

[0037] The dormant fish transfer device of this utility model has a simple structure and is easy to install. The automatic shaking of the dormant fish at the entrance of the diversion channel is realized through the shaking structure, which avoids the blockage of the diversion channel and ensures that the dormant fish are automatically and smoothly transported to the freezing conveyor line. It solves the technical problem in the prior art that the dormant fish block the entrance of the diversion channel, blocking the transport of the dormant fish and causing low production efficiency of the production line.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] like Figures 1 to 3As shown, a preferred embodiment of the present invention provides a swaying structure, characterized by including a fixed frame 1, a first platform 2, a first transmission rod 3, a second transmission rod 4, and a first driving member 5; the first platform 2 is horizontally slidably mounted on the fixed frame 1, and the first platform 2 includes a platform plate 21, which is aligned with the conveying surface of the conveyor line; one end of the first transmission rod 3 is hinged to the first end of the first platform 2; one end of the second transmission rod 4 is hinged to the other end of the first transmission rod 3; the first driving member 5 is fixedly disposed at the first end of the fixed frame 1, and the other end of the first driving member 5 is anti-rotationally connected to the second transmission rod 4; the length of the second transmission rod 4 is less than the length of the first transmission rod 3, and the first driving member 5 drives the second transmission rod 4 to rotate, thereby causing the first transmission rod 3 to sway, so that the first transmission rod 3 drives the first platform 2 to slide horizontally.

[0048] The swaying structure of this utility model embodiment drives the second transmission rod 4 to rotate in the horizontal plane through the first driving member 5. The second transmission rod 4 drives the first transmission rod 3 to swing, so that the end of the first transmission rod 3 connected to the first platform 2 moves closer to / away from the first driving member 5, thereby driving the first platform 2 to perform horizontal reciprocating motion, so as to realize the swaying of the dormant fish on the first platform 2, thereby adjusting the angle of the dormant fish body and avoiding blocking the conveyor channel on the production line.

[0049] Furthermore, such as Figure 2 and Figure 3 As shown, the first platform 2 includes a platform plate 21 and an upper frame 22. The platform plate 21 is fixedly installed on the upper frame 22. A horizontally extending slide rail 6 is provided on the fixed frame 1. The slide rail 6 has a groove 7 that extends along the length of the slide rail 6. A plurality of rollers 8 are provided at the bottom of the upper frame 22. The rollers 8 are spaced apart along the length of the slide rail 6 and roll along the groove 7. The first transmission rod 3 is hinged to the first end of the upper frame 22. In this embodiment of the present invention, there are two slide rails 6, both of which extend along the left and right sides of the swaying structure. Two rows of rollers 8 are provided at the bottom of the upper frame 22, and the two rows of rollers 8 roll within the two slide rails 6 respectively.

[0050] Furthermore, such as Figure 2As shown in this embodiment of the invention, the first driving component 5 is a drive motor, which is located on the right side of the fixed frame 1. The drive shaft of the drive motor is vertically upward. The second transmission rod 4 and the first transmission rod 3 are arranged horizontally. The first transmission rod 3 is positioned above the second transmission rod 4. One end of the second transmission rod 4 is fixedly connected to the drive shaft of the drive motor, and the other end is hinged to one end of the first transmission rod 3 via a pivot 19. The other end of the first transmission rod 3 is hinged to the upper frame 22 via a pivot 19. In use, the drive motor is started, and the drive motor drives the second transmission rod 4 to rotate in the horizontal plane. The second transmission rod 4 drives the first transmission rod 3 to swing, causing the end of the first transmission rod 3 connected to the upper frame 22 to move closer to / away from the drive motor, thereby causing the upper frame 22 to reciprocate in the left-right direction, thus achieving the shaking of the first platform 2.

[0051] Furthermore, such as Figure 1 and Figure 2 As shown, based on the swaying structure provided in the above embodiment, the dormant fish transfer device includes a swaying structure, a second platform 9, and a third platform 11. The sliding direction of the first platform 2 is perpendicular to the dormant fish conveying direction. The second platform is located in front of the dormant fish conveying direction. The second platform 9 is provided with a fish-pushing structure 10 for pushing the dormant fish on the second platform 9 to the first platform 2. The third platform 11 has multiple diversion channels 12, each diversion channel 12 extending along the dormant fish conveying direction. The outlet of the third platform 11 is connected to the freezing conveying line 18. The second platform 9 and the third platform 11 are respectively attached to the edge of the swaying structure. Along the dormant fish conveying direction, the first platform 2 and the third platform 11 are inclined downward in sequence, and the platform surface of the first platform 2 and the platform surface of the third platform 11 are coplanar.

[0052] In this embodiment of the dormant fish transfer device, to meet the power requirements for conveying dormant fish on the first platform 2 and the third platform 11, both the first platform 2 and the third platform 11 are inclined downwards along the conveying direction of the dormant fish, and the platform surface of the first platform 2 and the platform surface of the third platform 11 are coplanar, so that after the dormant fish enters the first platform 2 from the second platform 9, it can reliably slide forward through the first platform 2 and the third platform 11 under gravity. In use, after the dormant fish is conveyed to the working area of ​​the pusher structure 10, the pusher structure 10 conveys the dormant fish to the first platform 2 of the swaying structure. The dormant fish slides along the first platform 2 to the third platform 11, and then enters the freezing conveyor line 18 in sequence through the diversion channel 12. The freezing conveyor line 18 continues to convey the dormant fish to the freezing tunnel for freezing treatment. To prevent the hibernating fish from blocking the entrance of the diversion channel 12, the first driving component 5 of the swaying structure drives the first platform 2 to reciprocate along the direction perpendicular to the conveying direction of the hibernating fish through the first transmission rod 3 and the second transmission rod 4, so as to sway the hibernating fish on the first platform 2, thereby adjusting the angle of the hibernating fish body and allowing the hibernating fish to pass through the diversion channel 12 in sequence.

[0053] The dormant fish transfer device of this utility model embodiment has a simple structure and is easy to install. The dormant fish at the entrance of the diversion channel 12 is automatically shaken by the shaking structure, which avoids the blockage of the diversion channel 12 and ensures that the dormant fish is automatically and smoothly transported to the freezing conveyor line 18. This solves the technical problem in the prior art where the dormant fish block the entrance of the diversion channel, blocking the transport of the dormant fish and causing low production efficiency of the production line.

[0054] Furthermore, such as Figure 1 As shown, along the direction of transporting the dormant fish, the second platform 9, the swaying structure, and the third platform 11 are arranged sequentially. In this embodiment of the invention, the swaying direction of the swaying structure is perpendicular to the direction of transporting the dormant fish, that is, it sways along the left and right direction of the swaying structure. To meet the installation requirements of the swaying structure, the second platform 9 and the third platform 11 are respectively attached to the edge of the swaying structure, and the three are independent of each other to meet the working requirements of the swaying structure.

[0055] Furthermore, such as Figure 1 and Figure 2 As shown, the third platform 11 is provided with multiple vertically arranged diversion plates 13, each extending along the direction of transporting the dormant fish. These multiple diversion plates 13 are spaced apart along the direction perpendicular to the transport direction of the dormant fish, and the interval between each diversion plate 13 forms a diversion channel 12. Further, each diversion plate 13 includes a first segment 131 and a second segment 132 connected sequentially along the direction of transporting the dormant fish. Both sides of the first segment 131 are inclined outwards along the direction of transporting the dormant fish. The end faces of the first segment 131 and the second segment 132 that connect to each other have the same dimensions, making the diversion channel 12 form a funnel-shaped inlet, facilitating the entry of the dormant fish into the diversion channel 12. In this embodiment of the invention, the diversion plate 13 is made of steel plate, and the first segment 131 and the second segment 132 are welded together. Its surface is polished smooth to avoid damaging the exterior of the dormant fish. The interval between each diversion plate 13 is determined according to the size of the dormant fish, ensuring that only one dormant fish passes through at a time. Meanwhile, in order to prevent the sharp edges of the first segment 131 from damaging the fish, the end of the first segment 131 near the swaying structure is rounded and chamfered. This protects the fish from damage and facilitates the entry of the dormant fish into the diversion channel 12.

[0056] Furthermore, such as Figure 1 and Figure 4As shown, the second platform 9 is provided with two guide rails 14 extending along the direction of transporting dormant fish. The two guide rails 14 are arranged at intervals along the direction perpendicular to the direction of transporting dormant fish, that is, at intervals along the left and right directions of the second platform 9. The fish pushing structure 10 includes a moving rod 101, which is slidably mounted on the two guide rails 14 along the direction of transporting dormant fish. The moving rod 101 is provided with a push plate 102 that can move up and down. In this embodiment of the present invention, the moving rod 101 is placed on the guide rail 14. The top of the moving rod 101 is provided with a groove 17 extending along the length direction of the moving rod 101, and the groove 17 extends downward through the moving rod 101. The push plate 102 is vertically slidably mounted in the groove 17.

[0057] A second driving member 103 is provided on the guide rail 14. The second driving member 103 is connected to the moving rod 101. The second driving member 103 is used to drive the moving rod 101 to move closer to / away from the first platform 2. In this embodiment of the utility model, the second driving member 103 is a push cylinder. There are two second driving members 103, which are respectively fixedly installed on the sides of the two guide rails 14. The moving cylinder is arranged horizontally, and its output direction is the front and back direction of the guide rail 14. The output end of the push cylinder is fixedly connected to the moving rod 101 through a connecting plate.

[0058] A third driving member 104 is provided on the moving rod 101. The third driving member 104 is connected to the push plate 102 and is used to drive the push plate 102 to move up and down. In this embodiment of the present invention, the third driving member 104 is also a push cylinder. There are two third driving members 104, which are respectively fixedly installed on the top surfaces of both ends of the moving rod 101. The push cylinder is arranged vertically, and its output direction is vertical. The output end of the push cylinder is fixedly connected to the push plate 102.

[0059] When the dormant fish enters the working area of ​​the fish-pushing structure 10, the second drive component 103 is activated to push the moving rod 101 towards the swaying structure, which in turn drives the push plate 102 to push the dormant fish forward onto the first platform 2. At the same time, the second batch of dormant fish has arrived at the working area of ​​the fish-pushing structure 10. Then, the third drive component 104 is activated to lift the push plate 102, so that a gap is formed between the bottom of the push plate 102 and the surface of the second platform 9 for the dormant fish to pass through. The second drive component 103 pulls the moving rod 101 away from the swaying structure. When the moving rod 101 moves back to the appropriate position, the third drive component 104 is activated to make the push plate 102 move down to reduce the gap. Then, the second drive component 103 pushes the moving rod 101 towards the swaying structure. By repeating this process, the dormant fish can be transported. It should be noted that when the push plate 102 moves down, its bottom can directly contact the surface of the second platform 9, but it should not create resistance to the push plate 102. Of course, it is also acceptable to keep the bottom of the push plate 102 at a distance from the surface of the second platform 9, but this distance should not be allowed to pass through the hibernating fish.

[0060] Furthermore, in order to prevent damage to the fish body when the push plate 102 moves vertically, an anti-abrasion rubber strip 15 is provided at the bottom of the push plate 102. In this embodiment of the utility model, the anti-abrasion rubber strip 15 is a rubber strip, which is attached to the bottom edge of the push plate 102.

[0061] Furthermore, two position sensors 16 are provided on the guide rail 14, and the end of the moving rod 101 is located between the two position sensors 16. In this embodiment of the present invention, the position sensors 16 are proximity switches, and two proximity switches are provided on the guide rail 14 on the left side of the second platform 9, respectively, in the forward and backward directions of the push plate 102.

[0062] The dormant fish transfer device also includes a vision sensor and a controller. The controller is electrically connected to the vision sensor, position sensor 16, first drive unit 5, second drive unit 103, and third drive unit 104. In this embodiment of the invention, the vision sensor is an industrial camera, which is installed at the entrance of the freezing tunnel on the freezing conveyor line 18 to monitor whether the dormant fish enters the working area of ​​the fish-pushing structure 10.

[0063] When the dormant fish arrives at the working area of ​​the pusher structure 10, the industrial camera detects the presence of the dormant fish in the working area of ​​the pusher structure 10 and transmits the signal to the controller. The controller controls the second drive component 103 to start and push the dormant fish forward. At the same time, the controller controls the first drive component 5 to start, causing the first platform 2 to start shaking. After the dormant fish is pushed into the first platform 2, it enters the diversion channel 12 under the shaking of the shaking structure, and then enters the freezing conveyor line 18 in sequence through the diversion channel. The freezing conveyor line 18 then transports the dormant fish to the freezing tunnel for processing. When the moving rod 101 approaches the proximity switch in front, the dormant fish has been pushed into the first platform 2. The proximity switch transmits a signal to the controller, which controls the second drive component 103 to stop pushing forward and controls the third drive component 104 to lift the push plate 102. Subsequently, the controller controls the second drive component 103 to pull the moving rod 101 away from the swaying structure. When the moving rod 101 moves back and approaches the proximity switch behind, the proximity switch transmits a signal to the controller. The controller controls the third drive component 104 to lower the push plate 102 and activates the second drive component 103 to push the moving rod 101 towards the swaying structure. This process is repeated to transport the dormant fish. When the industrial camera detects that there is no dormant fish on the second platform 9, the industrial camera transmits a signal to the controller, which controls the first drive component 5, the second drive component 103, and the third drive component 104 to stop working.

[0064] In summary, the swaying structure provided by this utility model embodiment drives the second transmission rod 4 to rotate in the horizontal plane via a drive motor. The second transmission rod 4 drives the first transmission rod 3 to swing, causing one end of the first transmission rod 3 connected to the first platform 2 to move closer to / away from the first driving member 5, thereby driving the first platform 2 to perform horizontal reciprocating motion, so as to realize the swaying of the dormant fish on the first platform 2, thereby adjusting the angle of the dormant fish body and avoiding blockage of the conveyor channel on the production line.

[0065] In this embodiment of the dormant fish transfer device, to meet the power requirements for conveying dormant fish on the first platform 2 and the third platform 11, both the first platform 2 and the third platform 11 are inclined downwards along the conveying direction of the dormant fish, and the platform surface of the first platform 2 is coplanar with the platform surface of the third platform 11, so that after the dormant fish enters the first platform 2 from the second platform 9, it can reliably slide forward through the first platform 2 and the third platform 11 under gravity. In use, the dormant fish is conveyed to the working area of ​​the pusher structure 10, which conveys the dormant fish to the first platform 2 of the swaying structure. The dormant fish slides along the first platform 2 to the third platform 11, and then enters the freezing conveyor line in sequence through the diversion channel 12. The freezing conveyor line continues to convey the dormant fish into the freezing tunnel for freezing treatment. To avoid the dormant fish causing blockage at the entrance of the diversion channel, the drive motor of the swaying structure drives the first platform 2 to reciprocate along the direction perpendicular to the conveying direction of the dormant fish through the first transmission rod 3 and the second transmission rod 4, so as to realize the swaying of the dormant fish on the first platform, thereby adjusting the angle of the dormant fish body, so that the dormant fish pass through the diversion channel in sequence.

[0066] The controller is electrically connected to the vision sensor, position sensor 16, first drive unit 5, second drive unit 103 and third drive unit 104, realizing the automated operation of the dormant fish line-changing device, reducing worker involvement and improving production efficiency.

[0067] The dormant fish transfer device of this utility model has a simple structure and is easy to install. The automatic shaking of the dormant fish at the entrance of the diversion channel is realized through the shaking structure, which avoids the blockage of the diversion channel and ensures that the dormant fish are automatically and smoothly transported to the freezing conveyor line. It solves the technical problem in the prior art that the dormant fish block the entrance of the diversion channel, blocking the transport of the dormant fish and causing low production efficiency of the production line.

[0068] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
