Description

Technical Field

[0001] This utility model relates to the field of firecracker production technology, specifically a firecracker solid igniter dust recovery device. Background Technology

[0002] Firework fuse binder is an auxiliary material used in firework manufacturing to secure the fuse. Its main function is to firmly fix the fuse to the firework's propellant or casing, preventing it from loosening or falling off during transportation, storage, or ignition. This ensures the firework can ignite and burn properly, and also enhances the structural stability of the firework to some extent. Fuse binders typically have a certain degree of viscosity and curing properties. Their composition may vary depending on the specific process and requirements, but commonly includes clay, resin, and certain adhesive powders. When mixed, these components form a stable adhesive effect, ensuring a reliable bond between the fuse and the firework body.

[0003] However, during the stringing process of firecrackers, each firecracker tube is sealed with a igniter and then strung together after the igniter has cured. This involves connecting a large number of individual firecracker tubes into a string of firecrackers. However, during the stringing process, some of the dried igniter will scatter and form dust, thus polluting the environment.

[0004] Based on this, a firecracker igniter dust recovery device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content
