Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of integrated loading machines, and in particular to an integrated loading machine for inner cylinders used in the manufacture of fireworks and firecrackers. Background Technology
[0002] In the fireworks and firecrackers manufacturing industry, the inner cylinder filling is a key step in the production process. Its quality directly affects the combustion effect, safety, and overall quality of fireworks and firecrackers. The integrated inner cylinder filling machine, as the core equipment for realizing automated inner cylinder filling, integrates multiple functions such as inner cylinder conveying, powder metering, filling, and compaction. It aims to improve production efficiency, reduce the risks of manual operation, and ensure the stability of filling quality.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: Due to the lack of a correction mechanism, this positioning method is difficult to deal with the deviation that has already occurred in the inner cylinder during the conveying process. Even if the inner cylinder can be accurately positioned at the initial positioning, during the loading process, the injection of powder will generate a certain impact force on the inner cylinder. For some inner cylinders that are softer in texture or have an unstable structure, they may experience slight movement or shaking during the loading process, which will lead to deviation in the loading position.

[0022] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and accompanying drawings are only exemplary descriptions of the technical solution of this utility model, and should not be regarded as the whole of this utility model or as a limitation or restriction on the technical solution of this utility model.
[0023] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an integrated loading machine for fireworks and firecrackers, comprising a loading machine body 1; a conveying mechanism 2 is installed at the top of the loading machine body 1, and fixed blocks 3 are fixedly connected to both ends of the conveying mechanism 2; a support column 4 is fixedly connected to the top of the fixed block 3; an adjusting block 5 is fixedly connected to the top of the support column 4; an adjusting groove 6 is opened inside the adjusting block 5; an adjusting plate 7 is slidably connected inside the adjusting groove 6; a correction plate 8 is fixedly connected to the side of the adjusting plate 7 away from the adjusting block 5; and control grooves 9 are opened at both ends of the adjusting block 5, with control plates 1 slidably connected inside the control grooves 9. The bottom of the correction plate 8 has a through groove 11. The bottom of the control plate 10 is fixedly connected to a through block 12. The top of the adjustment plate 7 has an inner groove 13. Both sides of the inner groove 13 have several limiting grooves 14. The operator pulls the adjustment plate 7 to move the correction plate 8 and adjust it to the appropriate position. After adjustment, the operator aligns the through block 12 with the inside of the limiting groove 14 and pulls the control plate 10 to insert the through block 12 into the inside of the limiting groove 14, thus limiting the adjustment plate 7 and guiding the material.
[0024] Reference Figure 6 As shown in this embodiment: the size of the through block 12 is adapted to the size of the limiting groove 14, and the surface of the through block 12 is inserted into the interior of the limiting groove 14, so that the through block 12 can be stably inserted into the limiting groove 14 and is not easy to fall off, thereby ensuring the stability of the adjusting plate 7, and thus ensuring the accuracy of the material guidance of the correction plate 8.
[0025] Reference Figure 5As shown in this embodiment: a return spring 17 is fixedly connected to the side of the adjusting groove 6 away from the adjusting plate 7. The side of the return spring 17 away from the inside of the adjusting groove 6 is fixedly connected to the adjusting plate 7. When the operator pushes the adjusting plate 7 into the adjusting groove 6, the adjusting plate 7 pushes the return spring 17 to compress and store force. When the operator releases the limit of the adjusting plate 7, the return spring 17 quickly pushes the adjusting plate 7 to reset under the stored force, so as to realize the rapid guidance and positioning of the material.
[0026] Reference Figure 5 As shown in this embodiment: guide grooves 15 are provided on both sides of the inside of the adjusting groove 6, and guide blocks 16 are fixedly connected to both sides of the adjusting plate 7. The surface of the guide block 16 is slidably connected to the inside of the guide groove 15, which makes the adjusting plate 7 more stable when moving inside the adjusting groove 6 and less prone to deviation, further ensuring the stability of the adjusting plate 7 and the accuracy of the material guidance by the correction plate 8. At the same time, the cooperation of the guide groove 15 and the guide block 16 also plays a role in limiting the movement trajectory of the adjusting plate 7, so that the adjusting plate 7 can only move along the direction of the guide groove 15, avoiding the shaking or deviation of the adjusting plate 7 during movement, and further improving the guiding and positioning accuracy of the material.
[0027] Reference Figure 4 As shown in this embodiment: a thrust spring 18 is fixedly connected to the side of the control slot 9 away from the control plate 10. The side of the thrust spring 18 away from the control slot 9 is fixedly connected to the control plate 10. When the operator pushes the control plate 10 into the control slot 9, the control plate 10 compresses the thrust spring 18 to store force, and drives the through block 12 to release the limit between it and the limiting slot 14. When the operator releases the control plate 10, the thrust spring 18 quickly pushes the control plate 10 back to its original position under the stored force. At the same time, the through block 12 re-engages with the limiting slot 14 under the action of the reset spring. This design makes the control plate 10 more stable during the pushing and resetting process, and avoids the control plate 10 from shifting during the movement, which would affect the loading effect of the fireworks inner tube.
[0028] Reference Figure 4 As shown in this embodiment: both ends of the control groove 9 are provided with sliding grooves 19, and both ends of the control plate 10 are fixedly connected with sliders 20. The surface of the sliders 20 is slidably connected to the inside of the sliding grooves 19. When the operator pushes the control plate 10, the sliders 20 slide inside the sliding grooves 19, limiting the movement trajectory of the control plate 10, making the control plate 10 more stable during movement, avoiding the control plate 10 from shaking during movement, affecting the insertion and limiting effect between the through block 12 and the limiting groove 14, and further improving the stability of the inner cylinder drug filling machine during use.
[0029] Reference Figure 3As shown in this embodiment: the inside of the correction plate 8 is provided with several guide rollers 21. The surface of the guide rollers 21 rotates with the inner wall of the correction plate 8. When the inner tube of the fireworks and firecrackers deviates during the conveying process, the side wall of the inner tube contacts the surface of the guide rollers 21. Under the guidance of the guide rollers 21, the inner tube of the fireworks and firecrackers is corrected, so that the inner tube of the fireworks and firecrackers always maintains the correct position during the conveying process, and avoids the inner tube of the fireworks and firecrackers from deviating during the conveying process, which would affect the subsequent loading effect.
[0030] Working principle: By pulling the adjusting plate 7, the operator moves the correction plate 8 to the appropriate position. After adjustment, the operator aligns the through block 12 with the inside of the limiting groove 14 and pulls the control plate 10, causing the control plate 10 to insert the through block 12 into the limiting groove 14. This completes the limiting of the adjusting plate 7 and simultaneously guides the material, ensuring that the through block 12 is stably inserted into the limiting groove 14 and is not prone to falling out. This guarantees the stability of the adjusting plate 7 and, consequently, the accuracy of the correction plate 8 in guiding the material. When the operator pushes the adjusting plate 7 into the adjusting groove 6, the adjusting plate 7 moves... The return spring 17 is compressed and stores energy. When the operator releases the limit of the adjusting plate 7, the return spring 17, under the stored energy, quickly pushes the adjusting plate 7 back to its original position, achieving rapid guidance and positioning of the material. This makes the adjusting plate 7 more stable when moving inside the adjusting groove 6, less prone to deviation, further ensuring the stability of the adjusting plate 7 and the accuracy of the material guidance by the correction plate 8. At the same time, the cooperation of the guide groove 15 and the guide block 16 also limits the movement trajectory of the adjusting plate 7, ensuring that the adjusting plate 7 can only move along the direction of the guide groove 15, avoiding shaking or deviation of the adjusting plate 7 during movement, further improving the guidance and positioning accuracy of the material. When the operator pushes the control plate 10 into the control slot 9, the control plate 10 compresses the thrust spring 18 to store energy, causing the through block 12 to release its limit from the limiting slot 14. When the operator releases the control plate 10, the thrust spring 18, under the stored energy, quickly pushes the control plate 10 back to its original position. Simultaneously, the through block 12, under the action of the reset spring, re-engages with the limiting slot 14 for its limit position. This design makes the control plate 10 more stable during pushing and resetting, preventing the control plate 10 from shifting during movement and affecting the loading effect of the fireworks' inner tube. When the operator pushes the control plate 10, the slider 20 slides inside the slide groove 19, affecting the control plate 10. The movement trajectory of 0 is limited, making the control plate 10 more stable during movement and preventing it from shaking, which would affect the insertion and limiting effect between the through block 12 and the limiting groove 14. This further improves the stability of the inner cylinder loading machine during use. The surface of the guide roller 21 rotates with the inner wall of the correction plate 8. When the inner cylinder of the fireworks deviates during the conveying process, the side wall of the inner cylinder contacts the surface of the guide roller 21. Under the guidance of the guide roller 21, the inner cylinder of the fireworks is corrected, so that the inner cylinder of the fireworks always maintains the correct position during the conveying process, preventing the inner cylinder of the fireworks from deviating during the conveying process and affecting the subsequent loading effect.
[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
