Problems solved by technology

The existing process is cumbersome to operate and requires a lot of manpower. At the same time, the labor efficiency is low, and it is difficult to detect during the production process. Among them, the drilling, threading, and paper pressing must be performed in sequence, which greatly reduces the production cost. Labor efficiency; the safety performance of the fireworks prepared by the existing technology is not high. Since two holes are drilled in the position of the propellant on the wall of the outer cylinder, the force of the propellant is in the middle of the mud base and the paper, which greatly increases the quality requirements of the outer cylinder. There is a slight quality error in the outer cylinder or the mud bottom is loose, or the lead wire is drilled too large, and the hole is too high to easily break the fire. It often happens that the inside of the outer cylinder of the fireworks shell starts to explode, which brings safety to users who set off fireworks. Hidden danger
Because the lead wire is connected by two rounds, and it is a single short lead wire, if the insertion is not neat and in place, it will easily cause a fire break; if the paper is not compacted flat, it will easily lead to the leakage of the firing force and the explosion of the canister.
At the same time, since the propellant is under the paper, the force is diffused to the surroundings, and the pressure on the outer wall of the cylinder is relatively high, which can easily cause the cylinder to explode, and it is easy to cause the firing rhythm to be unstable due to string fire.

Abstract

The invention discloses safe firework based on axial internal cylinder inverted powder-charging technology. The firework comprises a base, a connecting lead wire and monomer firework cylinders, wherein the monomer firework cylinders are distributed on the base in an array mode; firework shells in all monomer firework cylinders are sequentially connected by the connecting lead wire; each monomer firework cylinder comprises an external cylinder, a firework shell, a propellant powder layer, a moistureproof layer and a power sealing layer; the firework shell, the propellant powder layer, the moistureproof layer and the power sealing layer are arranged inside the external cylinder; a propellant powder groove is formed in the upper part of the firework shell; the moistureproof layer is arranged on the upper part of the propellant powder layer; the power sealing layer is arranged on the upper part of the moistureproof layer; the firework shell comprises a firework powder layer, an over-fire mud bottom layer, the propellant powder groove, a wrapping layer and a firework shell lead wire; and the firework shell lead wire is connected with the connecting lead wire. The technology of the invention is simple, and by adopting the internal-external cylinder inverted powder-charging technology, the labor efficiency of preparation is improved, the materials are saved, the labor intensity is reduced, and the production of fireworks and the safety of setting off fireworks are increased.

Description

Technical field [0001] The invention belongs to a firework preparation process, in particular to a safety firework and a production process thereof based on the technology of inverted charging of the axial inner tube. Background technique [0002] In the existing firework preparation process, the outer cylinder is generally made first, and then the outer cylinder is filled with yellow mud from top to bottom to compact, arrange and assemble, drill holes, insert the lead wire connection equivalent to twice the outer diameter of the cylinder, and assemble the array. , Put on the propellant, cover with paper, load firework bomb, cover with paper, and finally pack. The existing process is cumbersome to operate, consumes a lot of manpower, is low in labor efficiency, and is difficult to detect during the production process. Among them, drilling, threading, and pressing must be performed in sequence, which greatly reduces Labor efficiency; the safety performance of the fireworks prepar...
