Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a fireworks gunpowder filling cartridge fixing device with a positioning structure, including a base frame 2, a filling mechanism 1 connected to the top of the base frame 2, and further including: The conveying mechanism 3 is installed inside the base frame 2, and the filling mechanism 1 is located above the conveying mechanism 3; The conveyor chain plate in the conveyor mechanism 3 is equipped with a clamping device 4. The clamping device 4 includes a pressing block 401 and multiple support blocks 405. A sliding groove 407 is formed in the support block 405, and a sliding rod 404 is slidably connected in the sliding groove 407. One end of the sliding rod 404 is connected to a support frame 402, and two transmission wheels 410 are rotatably connected to the inner wall of the support frame 402. A clamping block 408 is provided on the other side of the sliding rod 404. The sliding rod 404 is moved by the transmission of the conveyor mechanism 3. The cartridge case is clamped and fixed. The bottom of the support block 405 is connected to the surface of the conveyor chain plate in the conveying mechanism 3, and the bottom of the extrusion block 401 is connected to the top of the base frame 2. A spring 403 is sleeved on the outer wall of the sliding rod 404, and the two ends of the spring 403 are respectively connected to one side of the support block 405 and one side of the support frame 402. Two anti-deviation grooves 409 are opened on the inner wall of the sliding groove 407, and an anti-deviation strip 406 is slidably connected in the anti-deviation groove 409. One side of the anti-deviation strip 406 is connected to the outer wall of the sliding rod 404.

[0018] In a specific implementation, by setting up a clamping device 4, the cartridge is placed between two clamping blocks 408. Then, driven by the conveying mechanism 3, the conveying chain plate in the conveying mechanism 3 moves the cartridge, and the conveying chain plate moves the support block 405. The support block 405 moves the sliding rod 404, which in turn moves the transmission wheel 410 on one side. The transmission wheel 410 contacts the inclined surface of the extrusion block 401, causing the transmission wheel 410 to move inward. Through the support frame 402, the sliding rod 404 slides in the sliding groove 407. When the support frame 402 moves, it compresses the spring 403, causing the spring 403 to generate a rebound force, which in turn drives the sliding rod 404 to move... The movement of clamping blocks 408 allows the two clamping blocks 408 to clamp and fix the cartridge case, preventing it from shifting or tipping over during loading, thus avoiding the danger of gunpowder leakage. As the conveyor chain plate continues to move, the transmission wheel 410 separates from the other side of the extrusion block 401, and the rebound force of the spring 403 causes the two sliding rods 404 to separate, thereby removing the loaded cartridge case and improving the ease of use of the device. By setting an anti-deviation strip 406 to slide in the anti-deviation groove 409, the sliding rod 404 is prevented from rotating during movement, thus affecting the normal operation of the device. Furthermore, the filling mechanism 1 and the conveying mechanism 3 in this application are existing mature technologies and do not need to be described in detail.

[0019] The sliding rod 404 is equipped with an adjusting device 5, which includes a groove 503 and a connecting block 502. An adjusting rod 501 is connected to one side of the connecting block 502. The adjusting rod 501 has a through hole 505 with a thread, and a threaded rod 507 is threaded into the thread. The threaded rod 507 has a transmission hole 511, and two transmission grooves 510 are formed on the inner wall of the transmission hole 511. A transmission bar 509 is slidably connected in the transmission groove 510, and the two transmission bars 509 are connected to the same transmission rod 508. The end is connected to a connecting block 512, and a nut is connected to one side of the connecting block 512. A groove 503 is opened on one side of the clamping block 408, and one side of the through hole 505 extends to the groove 503 and is connected. The outer wall of the connecting block 512 is rotatably connected to the inner wall of the groove 503. The end of the threaded rod 507 away from the nut is rotatably connected to one side of the inner wall of the adjusting rod 501. One side of the connecting block 502 is connected to one side of the clamping block 408. Two sliding grooves 506 are opened on the inner wall of the sliding rod 404, and a sliding strip 504 is slidably connected in the sliding groove 506. One side of the sliding strip 504 is connected to the outer wall of the adjusting rod 501.

[0020] In a specific implementation, by setting an adjustment device 5, the screwdriver and nut cause the connecting block 512 to rotate, which in turn causes the transmission rod 508 to rotate. The transmission rod 508 then causes the transmission bar 509 to rotate. The transmission bar 509 slides within the transmission groove 510, causing the threaded rod 507 to rotate. This, in turn, causes the threaded rod 507 to rotate within the through hole 505. The thread within the through hole 505 causes the threaded rod 507 to move the adjustment rod 501, allowing the two adjustment rods 501 to adjust the distance between the two clamping blocks 408. This satisfies the need for fixing cartridges of different sizes. Furthermore, by setting a slide bar 504 to slide within the slide groove 506, the adjustment rod 501 is prevented from shifting during movement, thus avoiding jamming and affecting its use.

[0021] Working principle: In use, rotate the nut according to the size of the cartridge, and the nut will drive the connecting block 512 to rotate. The connecting block 512 will drive the transmission rod 508 to rotate. The transmission rod 508 will slide in the transmission groove 510 through the transmission bar 509, driving the threaded rod 507 to rotate. This will cause the threaded rod 507 to rotate in the thread within the through groove, which in turn will drive the adjusting rod 501 to move. The adjusting rod 501 will then drive the clamping block 408 to move through the connecting block 502, allowing the distance between the two clamping blocks 408 to be adjusted to fix cartridges of different sizes. Then, place the cartridge... The cartridge is positioned between the two clamping blocks 408, and then the conveying mechanism 3 drives the cartridge and support block 405 to move. This causes the support block 405 to drive the sliding rod 404 to move, which in turn drives the transmission wheel 410 to move via the support frame 402. One side of the transmission wheel 410 contacts the inclined surface of the extrusion block 401, causing the transmission wheel 410 to move inward. This, in turn, causes the transmission wheel 410 to drive the sliding rod 404 to move via the support frame 402. The sliding rod 404 then drives the clamping blocks 408 to move, so that the two clamping blocks 408 clamp and fix the cartridge, preventing the cartridge from tipping over and causing danger during filling.
