Abstract

The invention relates to the field of cold firework devices, in particular to a combustible metal powder supplementary device. The combustible metal powder supplementary device comprises a containingspace, a spiral transportation part in the containing space and a driving piece for driving the spiral transportation part to rotate, wherein the outer side of the spiral transportation part is attached to the inner side of a spiral feeding section. On the one hand, when the spiral transportation part rotates in the spiral feeding section, powder can be uniformly pushed downwards in the rotary motion direction of a spiral groove of the spiral transportation part under the dual actions of the gravity of the powder and the rotary push force of the spiral transportation part, and the aim of uniformly and stably supplementing powder is achieved; on the other hand, when the driving piece strops driving, because the spiral angle is small, and the linear distance is long, a discharging channel can be closed by the spiral transportation part, the powder is stopped from falling off, feeding is precise, and the powder is not stacked or stuck.

Description

technical field [0001] The invention relates to the field of cold pyrotechnic equipment, in particular to a combustible metal powder feeding device. Background technique [0002] With the development of society, entertainment and celebration activities are increasing, and people's requirements for the atmosphere of various activities are also increasing. In order to achieve a good on-site atmosphere, fireworks shows have become an indispensable part of various large-scale activities. Large-scale outdoors include the World Cup, Olympic Games, international large-scale conferences, concerts, etc., and indoor entertainment studios, Cold fireworks can be seen in private parties, wedding celebrations, corporate events, etc. [0003] Cold pyrotechnics is a new type of non-powder fireworks technology. It mainly uses a cold pyrotechnic device to heat combustible metal powder and then blows the powder out through a fan to form dazzling light to improve the atmosphere of the scene. ...
