Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of lead protection, specifically relates to a lead protection device for firework production. BACKGROUND

[0002] In the production of fireworks, lead is an essential raw material for production. Many fireworks production equipment will involve the processing of lead, such as lead machines, lead insertion machines, inner tube mud bottom machines, and group pot machines. In large-scale mechanized production, the lead inventory in the production site is large, and the lead is used in rolls (lead rolls) for standby, and is pulled to the production equipment for use. The flammable and fire-spreading characteristics of the working lead itself will also lead to the spread of fire, causing fires, property losses, and even casualties;

[0003] For example, the publication number CN214149011U discloses a lead safety protection device for firework production, which includes a lead pipe, a partition one is installed on one end of the lead pipe, a partition two is installed on the other end of the lead pipe, a heating structure is installed inside the partition one corresponding to the position of the lead pipe, a cutting device is installed at the middle position of the lead pipe, and an auxiliary device is installed on the partition two. The fish line is burned off by the lead, causing the cutter to move downward, thereby cutting off the lead.

[0004] In the production of fireworks, the lead needs to be protected to prevent it from being ignited. Some existing protection devices burn off the fish line or other material ropes by burning the lead, and then control the cutter to cut off the lead to prevent the lead from burning all the time. The above-mentioned patent has the following deficiencies. First, the fish line enters the lead pipe through a narrow hole. It is difficult to insert the fish line into the lead pipe again after each fish line is burned off. Second, when the lead burns in the lead pipe, a lot of residue will adhere to the inner wall of the lead pipe and be difficult to clean. The subsequent insertion of the lead into the lead pipe will cause damage to the outer wall of the lead. Utility model content

Figure 6

[0024] Specifically, the lower plate 8 bottom rotatably sets up the pivot 9, through setting up the pivot 9 on the lower plate 8 bottom, the friction between lead and pivot 9 can be reduced when lead moves, to play certain protective effect to lead.

[0025] ​Specifically, the moving block 11 is provided with two driving grooves 12, and the two ends of the driving rod 10 are correspondingly and slidably arranged in the two driving grooves 12. The side of the moving block 11 close to the cutter 18 is provided with a slope 13. When the moving block 11 moves towards the cutter 18, the cutter 18 is lifted by the abutment of the slope 13 and the abutment rod 15. When the moving block 11 moves away from the cutter 18, the cutter 18 is lowered to cut the lead wire. When the lifting plate 6 is lowered, the moving block 11 moves away from the cutter 18 by the cooperation of the driving rod 10 and the driving groove 12, so that the cutter 18 is lowered. When the lifting plate 6 is raised, the moving block 11 moves towards the cutter 18 by the cooperation of the driving rod 10 and the driving groove 12, so that the cutter 18 is lifted.

[0026] Specifically, the protection shell 1 is slidably provided with a connecting plate 16, and the two ends of the connecting plate 16 are fixedly provided with second springs 17. The ends of the second springs 17 away from the connecting plate 16 are fixedly connected with the protection shell 1. The connecting plate 16 is fixedly provided with a horizontal plate 14, and the horizontal plate 14 is fixedly connected with the abutment rod 15. The cutter 18 is fixedly connected with the connecting plate 16. The bottom of the abutment rod 15 is provided with a round head. The abutment rod 15 is fixedly connected with the connecting plate 16 through the horizontal plate 14. When the moving block 11 lifts the abutment rod 15, the connecting plate 16 is lifted through the horizontal plate 14. When the connecting plate 16 is lifted, the second springs 17 are stretched, and the cutter 18 is lifted at the same time. The protection shell 1 is provided with a second through groove 19 for the cutter 18 to pass through. When the moving block 11 moves away, the second springs 17 recover, so that the connecting plate 16 and the cutter 18 move downward, and the lead wire is cut off.

[0027] Specifically, the moving block 11 is provided with a slot 27, and the protection shell 1 is slidably provided with a plug rod 26 matched with the slot 27. When the lead wire under the pressing plate 8 burns, the first spring 7 drives the lifting plate 6 and the driving rod 10 to move downward, so as to pull the moving block 11 away from the cutter 18. At this time, the cutter 18 falls down. When the lead wire needs to pass through the pressing plate 8 and the cutter 18 again, the moving block 11 is pushed to move towards the cutter 18, and the abutment rod 15 is lifted by the slope 13, so that the cutter 18 is lifted. When the moving block 11 moves, the pressing plate 8 is lifted by the cooperation of the driving groove 12 and the driving rod 10. When the slot 27 of the moving block 11 moves to the position of the plug rod 26, the plug rod 26 is inserted into the slot 27. At this time, the moving block 11 is clamped, the first spring 7 will not drive the lifting plate 6 to move downward. Then, the plug rod 26 is pulled out after the lead wire is inserted into the first lead wire groove 2 and the second lead wire groove 4. At this time, the abutment of the pressing plate 8 prevents the moving block 11 from moving, so that the cutter 18 also does not fall down.

[0028] Specifically, a retaining plate 25 is slidably mounted on the protective housing 1, a first retaining groove 23 and a second retaining groove 24 are provided on the limiting plate 22, and a feeding groove 101 is provided at the bottom of the protective housing 1, which is connected to the first lead wire groove 2; the second through groove 19 is T-shaped, such as... Figure 6 As shown, the cleaning plate 21 can slide left and right within the short arm end in the middle of the second through groove 19. The protective housing 1 has a sliding groove 20 for the limiting plate 22 to slide. In the initial state, the cleaning plate 21 is located on the side of the first lead wire groove 2. At this time, the cleaning plate 21 will not interfere with the movement of the lead wire, and the locking plate 25 is locked in the second locking groove 24. The cooperation between the locking plate 25 and the second locking groove 24 prevents the cleaning plate 21 from moving. After the lead wire is cut, the moving block 11 lifts the cutter 18, and at this time the locking plate 25 is lifted. The limiting plate 22 is pushed towards the first lead groove 2. When the cleaning plate 21 is completely moved into the first lead groove 2, the clamping plate 25 falls into the first clamping groove 23. At this time, the limiting plate 22 is pushed towards the fixing block 3. The cleaning plate 21 is attached to the inner wall of the first lead groove 2. The clamping plate 25 has a guiding function. When the cleaning plate 21 moves, the residue adhering to the inner wall of the first lead groove 2 is scraped off. When the cleaning plate 21 moves to the discharge trough 101, the residue is pushed into the discharge trough 101, thereby completing the cleaning of the residue.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
