Environment-friendly firework launching rack capable of being filled repeatedly

Abstract

The invention discloses an environment-friendly firework launching rack capable of being filled repeatedly. The environment-friendly firework launching rack comprises a lower die holder (1) and an upper die holder (3); supporting platforms (15) are arranged on the lower die holder at intervals; platform sinking holes matched with the supporting platforms are formed in the upper die holder; an air duct capable of connecting and communicating with the supporting platforms in series is formed between the upper die holder and the lower die holder; the side edge of the first supporting platform is provided with a fire-leading channel (17) capable of being filled with a detonating fuse head; the periphery of the air duct is correspondingly provided with a sealing device capable of sealing the air duct; and the sealing device comprises sealing grooves (14) located in the lower die holder and sealing stripes (16) which are located on the upper die holder and can be embedded into the sealing grooves. According to the environment-friendly firework launching rack capable of being filled repeatedly, as the periphery of the hot airflow air duct is provided with the sealing device, thus, hot airflow can be controlled to be not leaked outwards, so that the hot airflow is enough to be subjected to ignition discharging, moreover, the hot airflow can flow orderly, and normal discharging of fireworks is ensured. The launching rack is compact in structure, convenient to manufacture, lightweight and high in durability.

Description

technical field [0001] The invention relates to the technical field of fireworks, in particular to a launching stand capable of repeatedly filling environment-friendly fireworks. Background technique [0002] As we all know, traditional fireworks are assembled from paper bobbins connected in series by multiple lead wires. It generally has to go through processes such as tube making, mud bottom pressing, insertion, nitrate and bright beads, sealing, assembly and packaging. Various, low production efficiency, high production cost, low standardization or standardization of products, poor working environment, high labor intensity, not conducive to mechanized production line operations, etc., and consume a lot of paper and soil, resulting in the loss of ecological resources waste, while also polluting the environment and destroying ecology. In response to these problems, some people use waste materials to make integral fireworks tubes by molding, and then set lead slots connecte...

Problems solved by technology

But it also has the following problems in use: the first is that the fireworks tube is not easy to reuse, and the discarded fireworks tube will pollute the environment; It is more complicated, the cost of the mold is high, and there are many presses, otherwise the mold must be replaced frequently, which will reduce the production efficiency; second, once a tube on the fireworks tube is damaged, it will cause the entire fireworks tube to be scrapped, increasing costs, recycling, It is not very convenient to collect and store, and it is also more troublesome to install the lead wires in series. Sometimes there will be lead wires strung together, causing quality problems such as fireworks cannot be set off, and affecting the quality of fireworks products.

This kind of combined fireworks is carried out in such a cycle that the hot gas generated by a fireworks discharge enters the adjacent fireworks tube through the air channel to heat the electric heating wire or directly ignites the fireworks with the hot air flow, but the launcher for loading the combined fireworks is in use There are still some problems: first, after using for a period of time, the upper and lower mold bases of the launcher loaded with fireworks will deform, causing the hot air channel formed by the upper and lower mold bases to leak, thereby reducing the pressure of the hot air flow and reducing the amount of heat. It affects the discharge of fireworks; the second is that the hot air channel is directly connected to the inner cavity of the launch tube at the lower end of the bullet, so that the flow direction of the hot air is scattered and the discharge speed is slow; the third is that the hot air flow sometimes occurs between adjacent launch tubes, causing the discharge It cannot be carried out in sequence, which will reduce the effect of the fireworks, and even cause the fireworks to fail to set off.
