Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0031] Please see Figures 1-7 The present invention provides the following technical solution:

[0032] A quick-change device for aquatic feed molding dies includes:

[0033] Feed feeder 1;

[0034] Mold slot 2 is located at the upper end of feed feeding cylinder 1;

[0035] Mold support 3, which is slidably connected to mold slot 2;

[0036] Feed forming ring 4, multiple feed forming rings 4 are provided, and multiple feed forming rings 4 are all located in the mold support 3;

[0037] The fixing mechanism consists of two sets. Each set includes a fixing slot 5, a spring groove 6, a fixing block 7, a fixing slot 8, a spring push plate 9, a fixing block 10, and a fixing spring 11. The fixing slot 5 is located at the lower end of the mold support 3. The spring groove 6 is located on one side of the inner wall of the fixing slot 5. The fixing block 7 is fixedly connected to the lower inner wall of the mold slot 2. The fixing slot 8 is located on one side of the fixing block 7. The spring push plate 9 is slidably connected to the spring groove 6. The fixing block 10 is fixedly connected to one side of the spring push plate 9 and slides within the fixing slot 8. The fixing spring 11 is fixedly connected to one side of the inner wall of the spring groove 6 and one side of the spring push plate 9.

[0038] In a specific embodiment of this utility model, the mold slot 2 is located at the outlet of the fish feed output machine. The mold support 3 can be quickly inserted and removed into the mold slot 2. The feed forming ring 4 is located in the mold support 3 and is used to shape the coarseness of the fish feed. When it is necessary to produce aquatic feed of different coarseness and size, the mold support 3 can be quickly replaced by a fixing component to replace the feed forming ring 4 with a different diameter through hole. During quick installation, the mold support 3 is aligned with the upper opening of the mold slot 2. At this time, the fixing block 7 also matches the lower opening of the fixing slot 5. After alignment, the mold support 3 is directly inserted into the mold slot 2. The fixing block 7 is also inserted into the fixing slot 5 at the same time and contacts the fixing clip 10. The contact surface between the fixing clip 10 and the fixing block 7 is an inclined surface, so that the fixing block 10... Block 7 presses the fixing block 10 and spring push plate 9 into the spring groove 6 and compresses the fixing spring 11 to retract until the mold support 3 is fully inserted into the mold slot 2. At this time, the fixing groove 8 opened on one side of the fixing block 7 slides to a position parallel to the fixing block 10. The previously compressed fixing spring 11 rebounds and pushes the fixing block 10 into the fixing groove 8 to complete the fixation of the fixing block 7. At this time, the fixing block 7 is restricted by the fixing block 10, and the mold support 3 can no longer be pulled out of the mold slot 2, thereby completing the quick replacement of the mold support 3. This device can quickly replace the feed forming ring 4 used for aquatic feed forming during aquatic feed production to make feed of different sizes and coarseness to meet the feeding requirements of different aquatic species.

[0039] Please refer to the details. Figures 1-7 The upper end of the mold support 3 is provided with a disassembly groove 12. The lower inner wall of the disassembly groove 12 and the side inner wall of the spring groove 6 are provided with a pull rope groove 13. A disassembly pull rope 15 is fixedly connected to one side end of the spring push plate 9. The disassembly pull rope 15 slides in the pull rope groove 13.

[0040] In this embodiment, a disassembly mechanism is provided at the upper end of the mold support 3. The disassembly mechanism can be quickly disassembled by a disassembly pull rope 15. One side of the disassembly pull rope 15 is located in the disassembly pull groove 12, and the other side is connected to the spring push plate 9 through the pull rope groove 13. When disassembling, the operator pulls the disassembly pull rope 15 upwards, and pulls the spring push plate 9 by the disassembly pull rope 15 to pull the fixing block 10 out of the fixing groove 8 and release the fixing restriction on the fixing insert 7. Then the operator can pull the mold support 3 out of the mold slot 2 for replacement.

[0041] Please refer to the details. Figures 1-7 A pull rope plate 14 is slidably connected inside the pull groove 12. The other side section of the pull rope groove 13 is fixedly connected to the lower end of the pull rope plate 14. A hand grip 16 is fixedly connected to the inner side wall of the pull groove 12.

[0042] In this embodiment: the pull rope grooves 13 of the disassembly mechanisms on both sides are fixed to the lower end of the pull rope plate 14. When the operator is disassembling, he holds the handle 16 with one hand, inserts his fingers into the lower end of the pull rope plate 14, and then squeezes his fingers to pull the pull rope plate 14 upward until it contacts the handle 16. At this time, the fixing block 10 and the fixing insert 7 have disengaged, and the operator can directly pull the mold bracket 3 out of the mold slot 2.

[0043] Please refer to the details. Figures 1-7 A fixed misalignment plate 17 is fixedly connected to the inner circumference of the feed feeding cylinder 1. A misalignment lifting groove 19 is provided on the inner circumference of the feed feeding cylinder 1. A movable misalignment plate 20 is slidably connected in the misalignment lifting groove 19. A misalignment sliding groove 18 is provided on the inner circumference of the feed feeding cylinder 1. A lifting push block 21 is fixedly connected to the lower end of the movable misalignment plate 20. The lifting push block 21 slides in the misalignment sliding groove 18. A misalignment spring 22 is fixedly connected to the lower end of the lifting push block 21 and the lower inner wall of the misalignment sliding groove 18.

[0044] In this embodiment: the device is equipped with an isolation mechanism so that when the mold support 3 is replaced, the raw materials used for feed production will not be squeezed out from the feed feeding cylinder 1. The fixed misalignment plate 17 and the movable misalignment plate 20 have the same shape and specifications, while the movable misalignment plate 20 moves up and down a certain distance within the misalignment lifting groove 19 opened on the inner wall of the feed feeding cylinder 1. The misalignment lifting groove 19 is opened on one side of the inner wall of the mold slot 2. The movable misalignment plate 20 slides between the mold support 3 and the movable misalignment plate 20. When the mold support 3 is inserted into the mold slot 2, the lower end of the mold support 3 presses the lifting push block 21, pushing the lifting push block 21 completely into the misalignment sliding groove 18. At this time, the misalignment spring 22 is also compressed. When the retracted and movable misaligned plate 20 is fully fitted with the fixed misaligned plate 17, the aquatic feed can be squeezed into the feed forming ring 4 from the discharge hole 23 for forming. When the mold support 3 is pulled out of the mold slot 2, the previously compressed misaligned spring 22 rebounds and pushes the lifting push block 21 to push the movable misaligned plate 20 against the upper inner wall of the misaligned lifting groove 19. At this time, the discharge hole 23 between the fixed misaligned plate 17 and the movable misaligned plate 20 is misaligned with each other, and the aquatic feed cannot pass through the movable misaligned plate 20 and the fixed misaligned plate 17 until the mold support 3 is reinserted. The isolation mechanism allows the device to be installed seamlessly without stopping the equipment when changing the mold, which improves the efficiency of mold changing.

[0045] Please refer to the details. Figures 1-7 Both the fixed misalignment plate 17 and the movable misalignment plate 20 have discharge holes 23 on their sides, and the discharge holes 23 are matched with the feed forming ring 4.

[0046] In this embodiment: each discharge hole 23 is connected to a feed forming ring 4. When the mold support 3 is inserted into the mold slot 2, the discharge holes 23 on the fixed misalignment plate 17 and the movable misalignment plate 20 overlap and fit with the feed forming ring 4 to extrude the aquatic feed from the feed forming ring 4 for forming.

[0047] Please refer to the details. Figures 1-7 The feed feeding cylinder 1 has an inlet 24 at its upper end.

[0048] In this embodiment: the feed inlet 24 is opened on the upper side of the feed feeding cylinder 1 for feeding. The device is equipped with a feeding auger. One end of the auger is connected to a drive motor. The drive motor drives the auger to rotate to continuously feed one end of the feed forming ring 4.

[0049] The working principle and usage process of this utility model: The mold slot 2 is located at the outlet of the fish feed output machine. The mold support 3 can be quickly inserted and removed into the mold slot 2. The feed forming ring 4 is located in the mold support 3 to shape the fish feed. When it is necessary to produce aquatic feed of different sizes and thicknesses, the mold support 3 can be quickly replaced with feed forming rings 4 with different diameter through holes through the fixing components. During quick installation, align the mold support 3 with the upper opening of the mold slot 2. At this time, the fixing block 7 also matches the lower opening of the fixing slot 5. After alignment, directly insert the mold support 3 into the mold slot 2. At the same time, the fixing block 7 is also inserted into the fixing slot 5 and contacts the fixing clip 10. The contact surface between the fixing clip 10 and the fixing block 7 is inclined, so that the fixing block 7 squeezes the fixing clip 10 and the spring push plate 9 into the spring groove 6 and squeezes the fixing spring 11 to retract until the mold support 3 is fully inserted into the mold slot 2. At this time, the fixing groove 8 on one side of the fixing block 7 slides parallel to the fixing clip 10. The previously compressed fixing spring 11 rebounds, pushing the fixing block 10 into the fixing slot 8 to secure the fixing block 7. At this point, the fixing block 10 restricts the fixing block 7, preventing the mold support 3 from being pulled out of the mold slot 2. This allows for quick replacement of the mold support 3, enabling the device to rapidly replace the feed forming ring 4 used for aquatic feed production to create feed of different sizes and textures, meeting the feeding requirements of different aquatic species. The upper end of the mold support 3 is provided with a disassembly mechanism. The disassembly mechanism can be quickly disassembled by a disassembly pull rope 15. One side of the disassembly pull rope 15 is located in the disassembly pull groove 12, and the other side is connected to the spring push plate 9 through the pull rope groove 13. When disassembling, the operator pulls the disassembly pull rope 15 upwards, and pulls the spring push plate 9 by the disassembly pull rope 15 to pull the fixing block 10 out of the fixing groove 8 and release the fixing restriction on the fixing block 7. Then the operator can pull the mold support 3 out of the mold slot 2 for replacement.

[0050] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
