Working principle of the gunpowder filling machine

Here is the working principle of the gunpowder filling machine according to the patent details:

• The gunpowder is fed into the feeding hopper from the powder box by a vibrating feeder. This controls the amount of gunpowder dosed.

• When the feeding hopper is lowered, a preset amount of gunpowder falls into the filling cylinder through the dosing port.

• Inside the filling cylinder, the ram compacts the gunpowder to densify it.

• The filling cylinder then ejects the compacted gunpowder cartridge.

• Between each filling cycle, the filling cylinder and ram are cleaned with high-pressure air to prepare for the next dosing.

• The rotating gunpowder tank positions each tube for filling in sequence. This ensures each tube gets filled uniformly.

• Clamping devices hold the gunpowder tubes firmly during the filling process.

• After filling the four types of gunpowder – black powder, metal salts, glycogen and antimony sulfide – the filled tube is further compacted and removed.

The key innovations are:

• The rotating gunpowder tank that positions each tube for filling uniformly
• The accurate dosing and compaction system that fills a preset amount of gunpowder each time
• The high-speed automatic filling process that can improve efficiency, consistency and safety compared to manual filling.

This gunpowder filling machine can meet the requirements for mechanical processing of fireworks while avoiding “dud fireworks” caused by human errors, ensuring the safety and quality of the fireworks.
