Feeding device for cold pyrotechnic eruption equipment and cold pyrotechnic eruption equipment

Abstract

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.

Description

technical field [0001] The invention relates to the field of cold pyrotechnic spraying devices, in particular, to a feeding device for cold pyrotechnic spraying equipment. Furthermore, the present invention also relates to a cold pyrotechnic device comprising the above-mentioned feeding device for a cold pyrotechnic device. Background technique [0002] Now various stage performances mostly set off cold fireworks to heighten the atmosphere and promote the climax of performances. In terms of realizing the stage effect, it has achieved very good results. [0003] The cold pyrotechnics set off on the stage at present all use the cold pyrotechnic cylinder of disposable discharge, and the mixture of gunpowder and metal powder is packed in the cold pyrotechnic cylinder and put into ignition head device. When the cold fireworks are set off, the ignition head device is controlled by electrical connection to generate sparks to ignite the gunpowder. The high temperature generated b...

Problems solved by technology

[0005] The invention provides a feeding device for cold pyrotechnic eruption equipment and cold pyrotechnic eruption equipment to solve the problem that the existing cold pyrotechnic feeding equipment is difficult to control the feeding stability of metal powder, and the feeding is discontinuous, and cannot be continuously fed. Uniformity, causing the eruption effect of cold fireworks to be uncontrollable, thus losing its function of showing the visual effect of the stage
