Description

Technical Field

[0001] The utility model relates to fireworks, namely fireworks devices for entertainment, display, lighting or signaling, and particularly relates to a gunpowder loading device for producing combined fireworks. Background Art

[0002] When combined fireworks are set off, they have good coherence and are very beautiful. When producing combined fireworks, gunpowder powder needs to be loaded into the combined firework pots so that after being set off, a reverse thrust can be generated in the firework tubes to push the ignited firework balls into the air and explode. Most of the existing gunpowder loading devices for producing combined fireworks load gunpowder into several single tubes in the combined fireworks manually, and then need to manually move to adjust the gunpowder loading positions of the several single tubes. The operation is troublesome and inconvenient to use, thus consuming a large amount of physical strength and time of workers, and then reducing the gunpowder loading efficiency of the combined fireworks. At the same time, when loading gunpowder into combined fireworks, most of them are directly placed on the workbench for gunpowder loading operations. However, during the gunpowder loading process, the combined fireworks may shake or tip over, which is likely to affect the normal progress of the gunpowder loading operation. Therefore, a gunpowder loading device for producing combined fireworks is needed to solve the above problems. Content of the Utility Model
