MATERIAL-FEEDING APPARATUS USED FOR COLD-FIREWORK ERUPTION DEVICE, AND COLD-FIREWORK ERUPTION DEVICE

摘要

Provided are a material-feeding apparatus used for a cold-firework eruption device, and a cold-firework eruption device. The material-feeding apparatus of the cold-firework eruption device comprises a material-feeding channel (4) used for receiving metal powder (2) continuously falling from a continuous material discharge apparatus (1) and delivering said metal powder (2) to an ignition area (3) for ignition; the material-feeding channel (4) is provided with a material feed opening (401) arranged corresponding to a material discharge opening (101) of the continuous material discharge apparatus (1); the material-feeding channel (4) is internally provided with a rotating material-feeding roller (5) disposed along the axial direction of the material-feeding channel (4) and used for continuously pushing the metal powder (2) falling out of the continuous material discharge apparatus (1); the outer surface of the rotating material-feeding roller (5) is provided with a continuous helical raised structure (501) and/or a continuous helical recessed structure (502). Accordingly, the continuity and uniformity of feeding of the metal powder (2) are ensured. By means of controlling the rotational speed of the rotating material-feeding roller (5), the effect of the cold firework eruption can be easily controlled, and the visual effects of the cold firework on the stage can be displayed very well.
