Granulation device for fireworks and gunpowder

Abstract

The invention discloses a granulation device for fireworks and gunpowder. The granulation device comprises a feeding inlet (1) and a mold box (2) arranged below the feeding inlet (1), wherein a mold groove and a first compressing head (10) for pressing the gunpowder, a second compressing head (11) and a film pressing head (12) which are arranged in sequence are formed in the bottom surface of theinner side of the mold box (2); and a mold groove corresponding to the bottom surface of the mold box (2) is formed in the lower surface of the film pressing head (12). The granulation device can realize automatic production, so that the personal safety of workers is guaranteed, the structure is compact, the space is saved, simultaneously the production efficiency is high, the granulation is uniform, subsequent manpower screening is not needed, and the production of different shapes of gunpowder particles can be realized by changing a mold pressing head, so that the granulation device is preferably applicable to the requirement of modern customization of fireworks.

Description

technical field [0001] The invention relates to a fireworks machine, in particular to a granulation device for fireworks powder. Background technique [0002] The fireworks industry with a long history has encountered a great crisis in recent years. First, the production safety situation is severe. Since the production of fireworks is mainly traditional manual and semi-mechanized production, accidental mistakes of workers will cause major safety accidents that cause casualties; Manual production, product specifications and quality are difficult to be guaranteed, resulting in safety accidents in product storage, transportation and discharge; third, the labor force is becoming more and more tense, labor costs are getting higher and higher, and the shortage of labor resources has restricted the development of the fireworks industry; Fourth, for safety reasons, the traditional fireworks production mode requires a scattered layout of workshops, occupying a large amount of land re...

Problems solved by technology

However, the above-mentioned granulation process through granulation discs has long granulation time and low efficiency, and at the same time, the size of the powder particles produced is difficult to control, resulting in the need for manual screening in the follow-up process, which further increases the working hours and increases the cost.

Moreover, the above method can only produce round gunpowder grains, and cannot produce gunpowder grains of other shapes, and cannot adapt to the customized development direction of modern fireworks.
