Subtitle pattern firework effect piece

Abstract

The invention discloses a subtitle pattern firework effect piece. The effect piece comprises a long column body formed by connecting a plurality of firework gunpowder short columns end to end and wrapped with a flame-retardant layer, the tail end of the long column body is connected with flame-retardant short columns to form effect single bodies, the effect single bodies are connected end to end and wrapped with an inner paper layer to form a long strip body, ignition fuses of the effect single bodies are connected with a quick fuse, and the long strip body and the quick fuse are wrapped withan outer paper layer. When the effect piece is set off, smoke gathering is not formed, light (flame) color pollution is not caused, and combustion flue gas of combustible substances other than firework gunpowder is greatly reduced; the firework gunpowder and other combustible substances are synchronously combusted, so that unordered bright spots cannot be formed; the firework gunpowder short columns can be made very thin, so that the resolution of a set-off image is greatly improved; and the effect piece is convenient to install and manufacture and low in cost.

Description

technical field [0001] The invention relates to a subtitle pattern fireworks. Background technique [0002] In the prior art, fireworks with subtitle patterns are mainly composed of fireworks effect tubes, which are also called "subtitle heads", "subtitle tubes", etc., and are filled with pyrotechnic effect medicines, and radially arranged on the side walls of the fireworks effect tubes. There are firework injection holes, and there are two connection positioning holes at the head and tail ends of the effect cylinder. The tail end of the effect cylinder and the head end of the other effect cylinder are connected to the positioning holes with a connecting line, so as to connect multiple effect cylinders. To form a whole, insert lead wires into the firework injection holes, connect the lead wires of each pyrotechnic effect tube in series with quick lead wires, then place the fireworks effect tubes connected with quick lead wires on the metal net in sequence according to the sh...

AI Technical Summary

Problems solved by technology

Its disadvantages are: first, the pyrotechnic powder burns in the airtight cylinder, which easily ignites the cylinder wall of the paper effect cylinder, and the paper burning smoke produced by the combustion of the cylinder wall is all discharged from the pyrotechnic injection port, so that the effect of the pyrotechnic powder is light and colorful. (flame color) is confused by burning paper smoke, and the purity of light color is reduced, making the red, blue, and green flame colors tend to be yellow, especially in the second half of the discharge, the light color pollution is more serious, which makes the color effect design of the discharge larger. Discount; second, after the pyrotechnic powder in the fireworks effect tube has been burned, some of the pyrotechnic effect tubes are still burning, and the disordered bright spots produced by the burning of the tube body seriously damage the display screen design

Third, the existing technology is complex, cumbersome to assemble, and the production efficiency is low, which causes the enterprise to generate relatively large production costs.
