Description

Technical Field:

[0001] This invention relates to firecracker production equipment, specifically a method for automatically filling firecrackers with gunpowder. Background technology:

[0002] Firework gunpowder is dry powder gunpowder, produced using a dry process. Prior to this invention, the filling method for dry powder gunpowder in firework production involved simulated batch filling. This method resulted in gunpowder mixing quantities reaching the kilogram level, low accuracy in gunpowder filling, and while a mechanized filling method, it required direct manual intervention, raising safety risks and environmental pollution concerns. To address these issues in firework production, this invention employs an automated gunpowder filling method for individual firework, reducing the gunpowder mixing quantity from the kilogram level to the gram level. This fundamentally solves the problems of firework safety and environmental pollution, achieving automated firework production. Summary of the Invention:

[0003] The purpose of this invention is to reduce the amount of gunpowder mixed in firecracker production. Gunpowder is a mixture of various raw materials, which is relatively safe before mixing, as each raw material individually poses no risk of deflagration. This invention utilizes this principle to mix a small amount of gunpowder for individual firecracker filling. The actual amount of gunpowder in a single firecracker is approximately 0.12 grams, which significantly improves the safety factor of firecracker production compared to the kilogram-level mixing amounts used previously. To achieve this goal, a volumetric metering device, a rotary mixing device, and a single firecracker gunpowder filling device have been invented. The key features are: the volumetric metering method is accurate and reliable; the rotary mixing method ensures uniform mixing; and the single firecracker gunpowder filling method uses a round-and-square gunpowder packaging module to fill equal portions into individual firecracker paper tubes. The metering, mixing, and filling processes are all automatically completed according to a program, achieving the goal of safe and automated firecracker production.

[0004] The key points of the invention are:

[0005] 1. The volume ratio of a volumetric metering device should be calculated based on the gunpowder ratio.

[0006] 2. The number of forward and reverse rotations of the rotary gunpowder mixing device must meet the requirement of uniform gunpowder mixing.

[0007] 3. The gunpowder filling of a single firecracker is done by a mold with a round base and a square top, and the machining accuracy of the mold directly affects the gunpowder filling accuracy.

[0008] The advantages of this invention are:

[0009] 1. The amount of gunpowder mixed is small, and the amount of gunpowder mixed at one time is calculated in grams, which greatly reduces the risk of deflagration.

[0010] 2. The gunpowder mixing and gunpowder filling are integrated into one design, eliminating the need for a separate process after gunpowder mixing, thus reducing the gunpowder explosion path. Attached image description:
