Detailed implementation manners

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below with reference to the accompanying drawings.

[0025] Please refer to Figures 1-7, a firecracker solid fuse sealing device. In the technical solution proposed by the present utility model, it includes a bottom plate 1. Two fixing frames 11 are fixedly arranged on the bottom plate 1. A storage box 21 is arranged between the two fixing frames 11. A clamping mechanism is arranged between the two fixing frames 11. A slider 13 is slidably arranged in each fixing frame 11. A first spring 14 is fixedly arranged between each slider 13 and the bottom plate 1. A lifting plate 17 is slidably arranged on each slider 13. Slide rods 18 are fixedly arranged on both sides of each lifting plate 17. Slide grooves 12 adapted to the slide rods 18 are opened on both sides of each fixing frame 11. A number of abutting protrusions 19 are fixedly arranged on one side of each lifting plate 17 close to the storage box 21. An abutting plate 25 is rotatably arranged on the storage box 21. A feeding mechanism is arranged at the bottom of the storage box 21; each slide rod 18 is slidably arranged in the corresponding slide groove 12 one by one. The storage box 21 is located in the middle position between the two fixing frames 11. The storage box 21 is used to put the solid fuse agent into the firecracker tube 4 on the bottom plate 1. In the initial state, the clamping mechanism is opened, the firecracker tube 4 to be sealed is placed in the middle of the clamping mechanism, the clamping mechanism is released, the clamping structure clamps the firecracker tube 4, the storage box 21 is moved downward, the abutting plate 25 on the storage box 21 moves downward accordingly. When the abutting plate 25 moves downward and abuts against the abutting protrusion 19, it will rotate, thus avoiding jamming. The upward-facing surface of the abutting protrusion 19 is set as an inclined surface. When the feeding mechanism below the storage box 21 is inserted into the firecracker tube 4, a part of the solid fuse agent in the storage box 21 is put into the firecracker tube 4. When the solid fuse agent is placed, the storage box 21 is moved upward. When the storage box 21 moves upward, it drives the abutting plate 25 to move upward. When the abutting plate 25 moves upward, it abuts against the lower side of the abutting protrusion 19, so that the abutting plate 25 drives the lifting plate 17 and the slider 13 to move upward. When the slider 13 moves upward, the clamping mechanism also moves upward accordingly, so that the firecracker tube 4 also moves upward. When the lifting plate 17 moves upward, the slide rod 18 also slides in the corresponding slide groove 12. At this time, the first spring 14 is stretched. As the lifting plate 17 moves upward, the lifting plate 17 moves away from the storage box 21 through the slide groove 12. When the abutting protrusion 19 on the lifting plate 17 is separated from the abutting plate 25, each slider 13 quickly moves downward through the first spring 14, so that the clamping mechanism drives the firecracker tube 4 to hit the bottom plate 1. As the abutting plate 25 abuts against each abutting protrusion 19, the firecracker tube 4 continuously hits the bottom plate 1, so that the solid fuse agent in the firecracker tube 4 is tightly squeezed against each other. When the storage box 21 rises to the initial position, the clamping mechanism is opened and the firecracker tube 4 is taken out and left standing. At this time, the firecracker tube 4 is completed with solid fuse sealing.

[0026] Specifically, each slide groove 12 includes a vertical portion 121 and an inclined portion 122 that are interconnected; the inclined portion 122 is above the vertical portion 121. When the abutting plate 25 drives the abutting protrusion 19 to move upward, the slide rod 18 also slides upward in the corresponding slide groove 12. When the slide rod 18 enters the inclined portion 122 from the vertical portion 121 of the corresponding slide groove 12, the abutting protrusion 19 gradually moves away from the abutting plate 25.

[0027] Specifically, the clamping mechanism includes clamping rods 16 slidably arranged on each slider 13. A clamping plate 161 is fixedly arranged at one end of each clamping rod 16 close to the storage box 21. A second spring 15 is fixedly arranged between each clamping rod 16 and each slider 13 in a one-to-one correspondence; a second spring 15 is arranged between the end of the clamping rod far from the clamping plate 161 and the corresponding slider 13. When it is necessary to fix and seal the firecracker tube 4, the two clamping rods 16 are pulled outwards to open the space between the two clamping plates 161, the firecracker tube 4 is placed between the two clamping plates 161, and the clamping plates 161 are released. At this time, the firecracker tube 4 is clamped in the middle of the two clamping plates 161. Both clamping plates 161 are V-shaped, and when the firecracker tube 4 is placed between the two clamping plates 161, it can automatically align with the axis of the storage box 21.

[0028] Specifically, a fixed ring 22 is fixedly arranged on the outer peripheral surface of the storage box 21. Two mounting brackets 24 are fixedly arranged on the fixed ring 22. Each abutting plate 25 is rotatably arranged in each mounting bracket 24. A torsion spring 26 is fixedly arranged between each abutting plate 25 and the corresponding mounting bracket 24. A limiting block 27 is fixedly arranged at the bottom of each mounting bracket 24; when the storage box 21 moves downward, it can drive the mounting bracket 24 and the abutting plate 25 to move downward. When the abutting plate 25 moves downward and abuts against the abutting convex block 19, the abutting plate 25 rotates upward. When the abutting plate 25 moves upward and abuts against the abutting convex block 19, the limiting block 27 makes the abutting plate 25 unable to rotate downward, so that when the storage box 21 moves upward, it can drive the two lifting plates 17 to move upward.

[0029] Specifically, the feeding mechanism includes a blanking tube 23 fixedly arranged at the bottom of the storage box 21. A first blocking plate 31 is fixedly arranged in the blanking tube 23. A second blocking plate 33 is rotatably arranged at the bottom of the first blocking plate 31. A plurality of material leakage holes 32 are formed on both the first blocking plate 31 and the second blocking plate 33. A horizontal groove 231 and an inclined groove 232 are formed on the outer peripheral surface of the blanking tube 23. A connecting rod 34 is fixedly arranged on the outer peripheral surface of the second blocking plate 33. The connecting rod 34 slides in the horizontal groove 231. A moving rod 35 slides in the inclined groove 232. A push rod 36 is fixedly arranged on the moving rod 35. The push rod 36 is slidably connected with the connecting rod 34; the material leakage holes 32 on the second blocking plate 33 are slightly smaller than the material leakage holes 32 on the first blocking plate 31. In the initial state, the second blocking plate 33 blocks the material leakage holes 32 on the first blocking plate 31, as Figure 6As shown, when the blanking cylinder 23 moves downward and extends into the firecracker cylinder 4 by a certain distance, the top wall of the firecracker cylinder 4 abuts against the moving rod 35. Through the inclined groove 232 and the cooperation, the moving rod 35 moves obliquely upward. While the moving rod 35 moves, it drives the connecting rod 34 to move through the push rod 36, so that the second sealing plate 33 rotates. At this time, the material leakage holes 32 on the first sealing plate 31 and the second sealing plate 33 are communicated, so as to put the solid primer in the storage box 21 into the firecracker cylinder 4.

[0030] Specifically, a third spring 37 is fixedly arranged in the horizontal groove 231, and the third spring 37 is fixedly connected with the connecting rod 34; one end of the third spring 37 is fixedly connected with the end of the horizontal groove 231, and the other end is fixedly connected with the connecting rod 34. When the storage box 21 moves downward, the second sealing plate 33 is driven to rotate through the moving rod 35 and the connecting rod 34. When the storage box 21 moves upward, the connecting rod 34 returns to the initial position through the third spring 37, so that the second sealing plate 33 seals the material leakage holes 32 on the first sealing plate 31 again, thus completing the automatic feeding of the solid primer.

[0031] Specifically, two support frames 2 are fixedly arranged on the bottom plate 1, and a cylinder 3 is fixedly arranged between the two support frames 2; the cylinder 3 is fixedly connected with the storage box 21; the up and down movement of the storage box 21 is controlled by the cylinder 3, so as to complete the automatic feeding of the solid primer and make the solid primer in the firecracker cylinder 4 abut tightly.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
