Device simulating firework spraying effect

Abstract

The invention discloses a device simulating the firework spraying effect. The device comprises a shell, a control cable and a controller, wherein the shell is provided with a firework spraying opening, a color generating metal bar, an electric grinding wheel and a drive motor of the electric grinding wheel are arranged in the shell, the color generating metal bar is arranged on a base arranged on a guide rail, the base or the color generating metal bar is connected with an air cylinder drive device, and the color generating metal bar is driven by the air cylinder drive device to do linear motion front and back in the direction from the guide rail to a friction plane of the electric grinding wheel. Requirements can be accurately and appropriately met by press fit force applied to the grinding wheel by the color generating metal bar without adjustment; a fixing and pushing mechanism of the color generating metal bar is greatly simplified, and work is more reliable; the press fit force can be conveniently and quickly adjusted by adjusting the air pressure of an air cylinder to achieve adjustments of different firework spraying heights.

Description

technical field [0001] The invention relates to the field of simulated fireworks, in particular to a device for imitating the effect of spraying fireworks. Background technique [0002] Present various stage performances mostly adopt the fireworks of spraying flowers to heighten the atmosphere and promote the climax of performances to occur. Good results have been achieved. Yet there are many insurmountable drawbacks in setting off fireworks on stage. Such as safety hazards, setting off smoke, spraying time, etc. CN1888809A discloses a friction-type multi-color spraying machine, which uses the friction between metal rods and electric grinding wheels to produce spraying effects, which solves the above problems, especially the safety guarantee performance is substantially improved compared with directly setting off fireworks. The color-making metal rod is driven by an electromagnetic propulsion device, which makes it press and rub against the electric grinding wheel to prod...

AI Technical Summary

Problems solved by technology

It is also driven by an electromagnetic propulsion device, and the feeding of the metal rod is mainly conveyed by clamping and feeding, and the pressing force, system coordination, controllability and stability of the metal rod and the electric grinding wheel in the equipment are improved: mainly due to the electromagnetic The advancement of the propeller is rigid, and the matching distance between the friction end of the color-making metal rod and the grinding wheel is fixed. With the consumption of the friction end of the color-making metal rod, the distance needs to be adjusted to meet the spraying requirements. Although the transportation method overcomes some defects, it also brings disadvantages such as complex system structure, heavy equipment, and high cost; at the same time, its controllability still needs to be further improved.
