Abstract

The invention discloses a feeding device for a cold firework eruption device and the cold firework eruption device. The feeding device for the cold firework eruption device comprises a feeding channel used for receiving continuously-falling metal powder from a continuous discharging device and conveying the metal powder to an ignition area to be ignited; the feeding channel is provided with a feeding opening corresponding to a discharging opening of the continuous discharging device, a rotary feeding roller which is arranged in the axial direction of the feeding channel and used for continuously pushing the metal powder falling from the continuous discharging device through circumferential rotation to the ignition area to be ignited is arranged in the feeding channel; and the outer surface of the rotary feeding roller is provided with continuous spiral protrusion structures and/or continuous spiral sunken structures. The continuity and the homogeneity of feeding of the metal powder are guaranteed. By controlling the rotating speed of the rotary feeding roller, the cold firework eruption effect can be easily controlled, and the visual effect of the cold firework stage effect can be better shown.

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...
