Description

Technical Field

[0001] This invention relates to the field of moisture-proof stacking technology, specifically a moisture-proof stacking device for molded fireworks bodies. Background Technology

[0002] Molded fireworks are a type of one-piece, one-time molded combination firework, formed by molding slurry. The molded body is obtained by heating and foaming the slurry within a mold cavity at high temperature and then drying it. The plant fibers, binders, fillers, excipients, and desiccants in its components have strong moisture absorption capabilities, requiring moisture-proof storage before packaging, especially in the humid and rainy seasons of southern regions. This is to prevent the quality of the pyrotechnic agents and fuses filled within the molded body from being affected, or the ignition effect. For example, Chinese invention patent document CN 110388854A discloses a "Moisture-proof Stacking Device for Molded Fireworks," which includes a base plate and a top plate supported by columns at four corners. Molded fireworks are stacked between the base plate and the top plate. A spool of moisture-proof material is located on one side of any column, parallel to the column. The spool is driven by a motor to unwind and rewind the moisture-proof material. The width of the moisture-proof material corresponds to the height of the base and top plates, and the free end of the moisture-proof material has a fixing strip with a handle. A hook is located on the outside of the spool.

[0003] The main drawbacks of the existing equipment are that the joints of the moisture-proof material are connected by hooks and handles, resulting in insufficient sealing. Although edge strips are installed to cover the connection between the sides of the moisture-proof material and the top and bottom plates, they cannot effectively prevent moisture from entering. This seriously affects the moisture-proof effect and restricts all-weather production in the main fireworks production areas in the south. At the same time, after the existing equipment surrounds the entire side of the stack with moisture-proof material, several edge strips need to be flipped. After use, workers need to flip and reset the edge strips one by one, which wastes a lot of time and affects work efficiency. With the improvement of equipment and processes in the production of molded fireworks, the scale of production lines is getting larger and larger, and the production efficiency is constantly improving. The workload of stacking and sealing the molded bodies is large, and higher requirements are placed on the convenience of stacking and sealing operations, which the existing equipment can hardly meet.

[0004] Based on this, a moisture-proof stacking device for molded fireworks is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0005] The purpose of this invention is to provide a moisture-proof stacking device for molded fireworks, which effectively improves the sealing and moisture-proof effect and the ease of operation.

[0010] In one alternative embodiment: the driving assembly includes a sliding rod that is slidably disposed within a perforation inside a fixed tube.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] Example 1

[0024] In one embodiment, such as Figures 1-6 As shown, a moisture-proof stacking device for molded fireworks includes a base plate 11. Several fixing pipes 13 are fixed to the upper end of the base plate 11, and a top plate 12 is fixed to the other end of each fixing pipe 13. A winding box 14 is fixed to one side of the base plate 11 and the top plate 12. A winding roller 15 is rotatably mounted inside the winding box 14. A moisture-proof curtain 16 is wound around the winding roller 15. A traction rod 17 is fixed to one end of the moisture-proof curtain 16. A rectangular perforation is provided on one side of the winding box 14 corresponding to one end of the moisture-proof curtain 16. Guide rails 19 are fitted at both ends of the traction rod 17, and two guide rails 19 are respectively fixed... The traction rod 17 is symmetrically provided with handles 18 on one side, and the rotating shaft of the winding roller 15 is fixedly connected to the output end of the motor 20. The motor 20 is fixedly installed inside the upper fixing frame of the winding box 14. The other side of the winding box 14 is provided with a locking mechanism to facilitate locking and fixing the traction rod 17. Both the bottom plate 11 and the top plate 12 are provided with sealing mechanisms to facilitate sealing both sides of the moisture-proof curtain 16. The locking mechanism facilitates quick fixing of the traction rod 17 and quick release of the traction rod 17. The sealing mechanism facilitates increasing the moisture-proof effect of the moisture-proof curtain 16 on the fireworks forming body.

[0025] The locking mechanism includes two limiting rods 21, which are fitted together on one side of the winding box 14 at positions corresponding to the handle 18. The limiting rods 21 are slidably disposed within rectangular sliding holes on a fixed box 22 on one side of the winding box 14. A fixed plate is fixedly installed inside the fixed box 22, and springs 23 are fixedly installed on both sides of the fixed plate. The other ends of the two springs 23 are respectively fixedly connected to one end of the two limiting rods 21. In use, when moisture protection is required for the firework-shaped body on the upper end of the base plate 11, the motor 20 is started, and the output end of the motor 20 drives the winding mechanism. As roller 15 rotates, the moisture-proof curtain 16 on the take-up roller 15 unfolds. The worker pulls the traction rod 17 along the guide groove on one side of the guide rail 19 using the handle 18. When the traction rod 17 moves to the other side of the take-up box 14, one edge of the handle 18 contacts one end of the limit rod 21 and pushes the limit rod 21 to slide into the fixed box 22. When one side of the traction rod 17 is in close contact with one side of the take-up box 14, the limit rod 21 returns to its initial position under the action of the spring 23, thereby fixing the traction rod 17 through the handle 18.

[0026] Each of the limiting rods 21 is fixed with a pull plate on one side, and the fixed box 22 is provided with a limiting groove on one side corresponding to the position of the pull plate. When it is necessary to release the fixation of the traction rod 17, the two pull plates are pulled at the same time, and the pull plates drive the two limiting rods 21 to move, thereby releasing the fixation of the traction rod 17.

[0027] The sealing mechanism includes a first sealing plate 24 and a second sealing plate 25. The first sealing plate 24 and the second sealing plate 25 are symmetrically arranged on the bottom plate 11 and the top plate 12. Telescopic rods 26 are symmetrically arranged on one side of the first sealing plate 24 and the second sealing plate 25. Several telescopic rods 26 are respectively fixedly arranged at the bottom end of the bottom plate 11 and the top end of the top plate 12. Threaded rods 27 are symmetrically arranged on one side of the first sealing plate 24 and the second sealing plate 25. The threaded rods 27 are fitted into the threaded holes on one side of the friction wheel 28. Both ends of the friction wheel 28 are provided with annular limiting grooves. Limiting tubes 29 are rotatably arranged in the annular limiting grooves. Several limiting tubes 29 are respectively fixedly arranged at the bottom end of the bottom plate 11 and the top end of the top plate 12. The top end of the top plate 12 is provided with a drive assembly to facilitate the rotation of the friction wheel 28. In use, the drive assembly drives the friction wheel 28 to rotate. When the friction wheel 28 rotates, the threaded rods 27 move along the axis of the friction wheel 28 under the action of the threads, thereby driving the first sealing plate 24 and the second sealing plate 25 to move.

[0028] The driving assembly includes a sliding rod 30, which is slidably disposed within a through hole inside the fixed tube 13. Rectangular through holes are provided on one side of the base plate 11 and top plate 12 at positions corresponding to the rectangular through holes inside the fixed tube 13. One side of each sliding rod 30 is in close contact with several friction wheels 28 on the base plate 11 and top plate 12. A connecting plate is fixedly disposed between two sliding rods 30 along the length of the top plate 12, and a fixed support plate is fixedly disposed between the two connecting plates. The bottom end of the fixed support plate is fixedly connected to the output end of the electric push rod 31. The electric push rod 31 is fixedly disposed... At the top of the top plate 12, when it is necessary to seal both sides of the moisture-proof curtain 16, the electric push rod 31 is activated. The output end of the electric push rod 31 drives several sliding rods 30 to move simultaneously through the fixed support plate and the connecting plate. One side of the sliding rod 30 is in close contact with several friction wheels 28. When the sliding rod 30 moves, it drives several friction wheels 28 to rotate, thereby causing several first sealing plates 24 and second sealing plates 25 to push one side of the moisture-proof curtain 16 to be in close contact with one side of the bottom plate 11 and the top plate 12, thereby increasing the moisture-proof effect of the firework molded body between the bottom plate 11 and the top plate 12.

[0029] Both the friction wheel 28 and the sliding rod 30 are provided with anti-slip layers, which facilitates the increase of friction between the friction wheel 28 and one side of the sliding rod 30 during use, thereby preventing the friction wheel 28 from slipping during use.

[0030] The bottom ends of the second sealing plates 25 on both sides of the base plate 11 are symmetrically provided with rectangular through holes, which facilitates the handling of the firework mold by forklift during use.

[0031] Example 2

[0032] The difference from Embodiment 1 is that a first sealing strip is fixedly provided on one side of the traction rod 17, and a second sealing strip is fixedly provided on one side of the winding box 14 where the fixed box 22 is located, corresponding to the position of the first sealing strip. In use, when the moisture-proof curtain 16 seals the fireworks molding body, the first sealing strip and the second sealing strip are tightly attached, thereby increasing the sealing effect between the traction rod 17 and the winding box 14.

[0033] The above embodiment discloses a moisture-proof stacking device for molded fireworks. When moisture-proof storage of the fireworks is required, several fireworks are placed on a base plate 11. Then, a motor 20 is started, and its output drives a winding roller 15 to rotate. A moisture-proof curtain 16 on the winding roller 15 unfolds. An operator pulls a traction rod 17 via a handle 18, which slides along a guide groove on one side of a guide rail 19. When the traction rod 17 moves to the other side of the winding box 14, one edge of the handle 18 contacts one end of a limiting rod 21, pushing the limiting rod 21 into the fixed box 22. When one side of the traction rod 17 is pressed tightly against one side of the winding box 14, the limiting rod 21 returns to its initial position under the action of a spring 23, thus allowing the limiting rod 21 to slide through the handle 18. The traction rod 17 is fixed, and the first sealing strip and the second sealing strip are tightly attached to each other, thereby increasing the sealing effect between the traction rod 17 and the winding box 14. The electric push rod 31 is activated. The output end of the electric push rod 31 drives several sliding rods 30 to move through the fixed support plate and the connecting plate. One side of the sliding rod 30 is tightly attached to several friction wheels 28. When the sliding rod 30 moves, it drives several friction wheels 28 to rotate. When the friction wheels 28 rotate, under the action of the thread, the threaded rod 27 moves along the axis of the friction wheel 28, thereby driving the first sealing plate 24 and the second sealing plate 25 to move. This causes several first sealing plates 24 and second sealing plates 25 to push one side of the moisture-proof curtain 16 to be tightly attached to one side of the bottom plate 11 and the top plate 12, thereby increasing the moisture-proof effect of the firework molding between the bottom plate 11 and the top plate 12.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
