Discharging device for cold firework eruption device and cold firework eruption device

Abstract

The invention discloses a discharging device for a cold firework eruption device and the cold firework eruption device. The discharging device for the cold firework eruption device comprises a charging hopper used for storing metal powder and a discharging hopper used for discharging the metal powder; a rotary feeding mechanism for continuously pushing the metal powder in the charging hopper into the discharging hopper through circumferential rotation is arranged between the lower portion of the charging hopper and the upper portion of the discharging hopper, the rotary feeding mechanism is installed on the charging hopper, and the output end of the rotary feeding mechanism faces the interior of the discharging hopper; and the output end of the discharging hopper is communicated to a conveying mechanism which is used for heating the metal powder and conveying the metal powder to a next working procedure. Through stable rotation and the constancy of the surface condition of a rotation body, the conveying amount of the metal powder in the conveying process keeps constant all the time, the metal powder conveyed to cold firework eruption keeps constant in quantity and speed all the time, the cold firework eruption effect can be better controlled, and the cold firework stage effect can be better shown.

Description

technical field [0001] The invention relates to the field of cold pyrotechnic injection devices, in particular, to a material unloading device for cold pyrotechnic injection equipment. In addition, the present invention also relates to a cold pyrotechnic device comprising the above-mentioned unloading device for the 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 temper...

Problems solved by technology

[0005] The invention provides a blanking device for cold pyrotechnic eruption equipment and cold pyrotechnic eruption equipment to solve the problem that the metal powder blanking mechanism used for cold pyrotechnic eruption equipment is difficult to control the stability of metal powder blanking in blanking, There is discontinuity in the blanking, it cannot be continuously blanked, and the blanking is uneven, resulting in an uncontrollable eruption effect of cold fireworks, thus losing its technical problem of showing the visual effect of the stage
