Description

Technical Field

[0001] This utility model relates to the field of fireworks production technology, and more specifically, to a fireworks agent filling device. Background Technology

[0002] Fireworks, also known as sparklers, fireworks, or firecrackers, are often used in grand ceremonies or performances. During the production process, prepared chemicals are filled into the cannon tubes.

[0003] A search revealed Chinese patent application CN202420897369.6, which discloses a fireworks powder filling device, comprising: a housing; a fixed block rotatably disposed within the housing; fixed blades arranged in a circular array on the side wall of the fixed block; and rotating blades arranged in a circular array on the side wall of the fixed block and rotatably engaged, with the gap between the rotating blades and the fixed blades forming a cavity. This utility model provides a fireworks powder filling device where, during continuous rotation, the powder collected in the cavity is filled into the cannon barrel. Furthermore, the cavity formed between the rotating blades and the fixed blades is of uniform size, ensuring a consistent amount of powder in each firework. When the amount of powder in the firework needs to be increased, the rotating blades are driven to rotate clockwise along the fixed block, causing the rotating blades and fixed blades to merge, thereby merging the two cavities and increasing the amount of powder collected. This rapidly increases the amount of fireworks powder filled, avoiding the need for lengthy adjustments to the filling device and reducing production efficiency.

[0004] Although the aforementioned patent can achieve the function of quantitative filling, it still has the following shortcomings in use: it is inconvenient to continuously fill the agent into different barrels in the existing technology. After filling one barrel, it is necessary to manually take the other barrel over for filling, which results in low efficiency of agent filling. At the same time, the agent filling in the existing technology is done manually, and it is necessary to frequently add material to the box, resulting in low automation.

[0005] Therefore, there is an urgent need for a fireworks powder filling device to solve the above problems. Utility Model Content

The transmission wheel 604 drives the intermittent wheel 602 to rotate, thereby causing the turntable 4 to rotate intermittently, thus conveying the cannon barrel to directly below the output pipe 809. At this time, the metering cylinder 804 on the rear side is located below the powder storage cylinder 801, and the powder is filled into the metering cylinder. 804. Controller 9 controls the second servo motor 807 to work. The second servo motor 807 drives the receiving plate 803 to rotate 180 degrees, so that the metering cylinder 804 filled with the agent moves above the output pipe 809. The agent falls into the barrel through the output pipe 809. The empty metering cylinder 804 at the front enters below the output end of the storage cylinder 801 to receive the agent for the next filling. At this time, controller 9 triggers the second servo motor 807 to stop working. After the next barrel is conveyed to the filling position, it is filled again. After the filling is completed, the barrel is conveyed to the conveying mechanism 7 on the right side by the intermittent rotation of the turntable 4 and sent out.
