Description

Technical Field

[0001] This utility model relates to the field of quantitative loading technology for fireworks and firecrackers, and in particular to a quantitative loading device for fireworks and firecrackers. Background Technology

[0002] Fireworks and firecrackers refer to arts and crafts made from gunpowder, which are entertainment products that burn and explode through an ignition source, accompanied by sound, light, color, smoke, fog and other effects. The original purpose of firecrackers was to welcome gods and drive away ghosts. Fireworks are works of art with visual effects as the main focus. Later, with their strong festive color, they developed into a symbolic symbol of bidding farewell to the old year and welcoming the new.

[0003] Quantitative loading of fireworks and firecrackers refers to the precise control of the amount of pyrotechnic or explosive powder loaded in each product during the production process, in accordance with national safety standards and product design requirements. This process uses specialized measuring instruments and automated equipment to ensure that the amount of powder in each product is consistent, avoiding excessive explosive power due to too much powder or insufficient powder affecting the ignition effect. Quantitative loading is not only an important link in ensuring the stability of product performance, but also a key measure to prevent safety accidents during production and use.

[0004] In traditional friction-type feeding structures, drugs can easily get trapped between the feeding plate, the metering plate, and the slide due to the gaps in their fit. The friction and compression during mechanical sliding can cause the drugs to heat up, and may even lead to combustion and explosion accidents.

[0005] Therefore, it is necessary to provide a device for quantitatively loading fireworks and firecrackers to solve the above-mentioned technical problems. Utility Model Content

[0048] The working principle of the fireworks and firecrackers quantitative charging device provided by this utility model is as follows:

[0049] The feeding plate 15 is slidably connected to the slide groove 19 on the top of the mounting frame 6 via multiple silent pulleys 18. With the help of the telescopic component 5, the feeding plate 15 can move on the mounting frame 6, aligning with the metering frame 13. The telescopic component 14 extends and retracts, causing the metering frame 13 to move up and down, allowing the rubber frame 17 on the top of the feeding plate 15 to engage with the mating frame 22 at the bottom of the metering frame 13, increasing the connection seal. Combined with the discharge plate 8 and the charging tube 23, the gunpowder inside the hopper 9 can be loaded into the fireworks in the placement opening 30. In actual use, first select the corresponding model and number of holes for the discharge plate 8 and the metering plate 24 and install them respectively. Inside the feeding hopper 9 and the metering frame 13, the fireworks are placed inside the placement opening 30. The telescopic component 5 pushes the feeding plate 15 to move below the metering frame 13.

The gunpowder can then be introduced into the feeding hopper 9 and fall along the discharge plate 8 and the charging tube 23 onto the metering plate 24. The gunpowder then enters the fireworks through the holes on the metering plate 24. After the charging is completed, the telescopic component 14 drives the metering frame 13 to reset, and at the same time, the telescopic component 5 moves the feeding plate 15 out to remove the charged fireworks.

[0050] Compared with related technologies, the fireworks and firecrackers quantitative charging device provided by this utility model has the following beneficial effects:

[0051] To reduce safety hazards during the quantitative loading of fireworks and firecrackers, the feeding plate 15 is slidably connected to the slide groove 19 on the top of the mounting frame 6 via multiple silent pulleys 18. With the help of the telescopic component 5, the feeding plate 15 can move on the mounting frame 6, aligning with the quantitative frame 13. The telescopic component 14 extends and retracts, causing the quantitative frame 13 to move up and down, allowing the rubber frame 17 on the top of the feeding plate 15 to engage with the docking frame 22 at the bottom of the quantitative frame 13, increasing the connection seal. Combined with the discharge plate 8 and the loading tube 23, the gunpowder inside the discharge hopper 9 can be loaded into the fireworks and firecrackers in the placement opening 30. This design uses silent pulleys 18 to move the feeding plate 15, reducing friction and heat generation. The vertical alignment of the feeding plate 15 and the quantitative frame 13, along with the rubber frame 17 and docking frame 22, increases the seal and reduces gunpowder spillage, significantly reducing safety hazards during the quantitative loading of fireworks and firecrackers.
