TECHNICAL FIELD

[0001] The utility model relates to the field of firecracker production, especially to a fuse cutting device. BACKGROUND

[0002] Fuse cutting is an important step in the production process of fireworks and firecrackers, used to ensure the uniformity of the length of the fuse, to improve the safety and the effect of the fireworks and firecrackers. The fuse is one of the key components in fireworks and firecrackers, used to ignite the gunpowder in fireworks and firecrackers, to control the ignition time of fireworks and firecrackers.

[0003] The role of cutting the fuse of finished fireworks into a uniform length is very important, which not only relates to the safety of fireworks, but also directly affects the visual effect and the experience of watching fireworks during the burning. The uniform length of the fuse can ensure that the ignition time of each firework is roughly the same, reducing the accidental early or delayed ignition caused by the length difference of the fuse, and reducing the safety hazard. The standardized length of the fuse helps to control the ignition sequence of fireworks, ensuring that fireworks are burned in turn according to the plan, avoiding chaos or out-of-control situations. Therefore, in actual use, the fuse of fireworks and firecrackers usually needs to be cut, but the fuse of existing fireworks and firecrackers is usually not cut to a uniform state, and needs to be adjusted during actual use. However, the adjustment during actual use is inconvenient, and the non-uniform fuse after production completion leads to poor aesthetics of the packaging of fireworks and firecrackers.
