Description

Technical Field

[0001] The present invention relates to the technical field of material conveying, in particular to an automatic feeding and conveying device for a strip cutting machine. Background Art

[0002] Fireworks and firecrackers are made of pyrotechnic powder as the main raw material. After ignition, they burn or explode to produce light, sound, color, shape, smoke and other effects for viewing. Fireworks are products that can form colors, patterns, and sound effects when set off, and are mainly visual products. Firecrackers are products that explode when set off and can produce effects such as popping sounds and flashes, and are mainly auditory products. Short paper tubes are containers for gunpowder.
