Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0014] refer to figure 1 , the manufacturing process of cylindrical small fireworks shell fireworks, comprising the following process steps:

[0015] 1) To pull the cylinder, use a reel machine to process high tile papers of different thicknesses into a cylinder body 1 according to the design specifications, and set an ignition lead wire installation hole on the bottom side of the cylinder body 1.

[0016] 2) Set an intermediate isolation mud layer, and use yellow mud to set an isolation mud layer 2 near the bottom of the cylinder. The lower part of the isolation mud layer 2 is the propellant chamber 3, and the size of the propellant chamber is determined according to the product charge. The upper part of the isolation mud layer is the effect medicine chamber 4, and the size of the effect medicine chamber 4 is determined according to the char...

Abstract

The invention provides a process for manufacturing cylindrical small display-shell fireworks. In order to solve the problem of combining the prior display shell with propellant, the process adopts a technical scheme that the process comprises the steps of pulling a cylinder, setting a middle isolation mud layer, installing an ignition lead and the like, and the ignition lead passes through the isolation mud layer and is in fire-spreading connection with drugs in a propellant chamber and an effect drug chamber. The process has the advantages of reducing material consumption of cylinder bodies and reducing cost, along with simplicity, applicability and high production efficiency.

Description

technical field [0001] The invention relates to the production of fireworks, in particular to a production process of cylindrical small fireworks shell fireworks. Background technique [0002] Small fireworks bombs are also called small artillery shells. The current small fireworks bombs place effect medicine and explosives in the spherical shell or cylindrical shell, and connect the explosives with a timing lead. When launching, after the timing fuse is ignited, the small fireworks bombs are detonated to produce sound and light. Effect. There are some technical problems in this kind of small fireworks shell. Usually, the propellant and ignition fuse are preset on the launching device, the small fireworks shell is put into the launch tube, and the ignition fuse is ignited for discharge. It is a technical problem to be solved at present to design a new product that does not need to be provided with a small display shell with propellant and ignition fuse on the launcher, and ...
