A kind of gunpowder block of graphic firework dot-matrix projectile and its manufacturing method

Abstract

The invention discloses a gunpowder block of a graphic firework dot matrix projectile and a method for making the same. A sealing layer is provided above the pyrotechnic display charge, and a sealing layer is provided below the pyrotechnic propellant charge, and the sealing layer and the sealing layer are connected to the casing; the method for making the propellant block includes: Step 1: Paste a layer of sealing layer on the bottom of the body; step 2: place the shell pasted with the sealing layer in a jig for positioning; step 3: pour an appropriate amount of fireworks propellant into the shell. The firework powder block with pictures and texts provided by the present invention can be produced by a special jig, which not only meets the needs of mechanized integrated production, but also has high production efficiency, low production cost, and simple manufacturing process, which is conducive to standardized design and reduces the cost of fireworks with pictures and texts. cost so that it can be used by the general public.

Description

technical field [0001] The invention relates to the field of fireworks, in particular to a gunpowder block of a graphic firework dot matrix emitter and a method for making the same. Background technique [0002] Fireworks are products that can form colors, patterns, and produce sound effects when they are set off, and are mainly visual effects. At first, fireworks were a pastime exclusively for the rich and the rich. In the Ming and Qing Dynasties, the technology of fireworks production had new developments, and gradually became festival gifts. Every Spring Festival, Lantern Festival and other major events, fireworks are set off to add to the fun. [0003] There are many types of fireworks in our country, and the designs and colors are quite mixed. Among them, the chrysanthemum type is the most popular flower type. After the fireworks are shot into the sky, first the colorful light agents burn, and then the parachutes that open and fall one by one. The fireworks overlap, ...

AI Technical Summary

Problems solved by technology

However, since the price of fireworks that can form pictures and texts in the sky is much higher than that of ordinary fireworks on the market, there were very few batches of pictures and texts for sale before this, and they were usually ordered by the government or enterprises

[0004] Nowadays, with the improvement of living standards, people's entertainment requirements and consumption vision are also constantly improving. Fireworks are an old-fashioned product that has lasted for thousands of years. There are many types of fireworks, and many classic products have been derived. However, with the development of science and technology, the original model has basically developed to the top. It is a new type of firework product that can be popularized and everyone can consume. In large-scale events, such as the Olympic Games, people use countless pictures of fireworks, and use a large number of people and many computers to control them simultaneously to generate footprints in the sky. However, this method It requires a lot of manpower and material resources, is expensive, and requires multiple coordination and training, so it is difficult for people to copy and bear this kind of consumption. At present, some companies and individuals have made some attempts and research on graphic fireworks. These individuals and companies have : Zhou Zhengjiang, Zhou Zhengkai, Liuyang Yushi Science and Technology Environmental Protection Fireworks Factory, Yu Peichu, Yu Benyou, Liuyang Dahu Fireworks Art Fireworks Display Group Co., Ltd., Liuyang Celebration Fireworks Culture Group Co., Ltd., etc., have also applied for dozens of patents, However, its research and development ideas and technical improvements have not yet broken away from the original development framework, and there have been no major breakthroughs. In practical applications, there are a large number of problems in manufacturing, packaging and transportation, discharge, simple graphics, etc., and the cost is high and the volume is large. , Inconvenient to use, difficult to apply, popularize and use. The key to making graphic fireworks is the graphic fireworks lattice structure and the powder block used to assemble in the lattice structure. The cost of its manufacture, the lattice contained in the unit area The number of dots, production efficiency and reliability of simultaneous launch, only by solving the problem of the lattice structure and its propellant block, can the graphic fireworks be simple and practical in structure, easy to manufacture, suitable for large-scale and efficient production, low in cost, suitable for Popular use, so that everyone can use it if they want to use it, and can afford it
