Due to the screw structure of the lowering screw (the lowering roller shaft 302), the metal powder 5 in the charging hopper 1 can be adjusted by adjusting the gap between the lowering screw (the lowering roller shaft 302) and the bottom of the charging hopper 1. The complete blanking is carried out into the feeding device (conveying mechanism 4), thereby solving the problem of the remaining amount when the metal powder 5 is discharged.

Solved the problem of unstable and discontinuous flame when the cold fireworks eruption equipment erupted. Due to the structural characteristics of the unloading device, the metal powder 5 can be uniformly, smoothly and continuously slipped from the lowering funnel 2 to the feeding screw 401, and the uniform rotation speed of the feeding drive motor further ensures the feeding screw 401. The uniformity, smoothness and continuity of the upper metal powder 5 realize the uniformity, stability and continuity of the flame during the eruption of the cold flame fire erupting device.

Solved the problem of large noise when cold fireworks are cut. The feeding device adopts a gear motor and a screw rod structure to replace the electromagnet and the push rod structure to cut off the material, which can eliminate the noise generated when the electromagnet sucks the push rod, and effectively avoid the jam of the cutting material, thereby solving the problem of the cold flame fire erupting equipment cutting. Problems such as large noise, discontinuity, and poor stability.
