According to the invention, paper for the reel is cleaned and reinforced, one side of the paper is covered and bonded with the flexible net through the viscose, and the subsequent flexible net is curled to the inner side wall of the reel, so that the structural strength of the formed reel can be uniformly enhanced, and the auxiliary fixing effect on yellow mud and black powder in the reel is also realized, so that the firework structure is more stable and the safety is better.)

1. A method for manufacturing fireworks with high safety is characterized in that: the method comprises the following steps:

a. selecting paper with uniform and smooth texture, blowing air to clean two sides of the selected paper, coating an adhesive layer on one side of the paper, and covering and bonding a flexible net on the adhesive layer;

b. drying the surface of the paper, which is bonded with the flexible net, and curling the dried paper into a paper cylinder for later use;

c. b, opening the paper tube manufactured in the step b and feeding the paper tube into a firework tube rolling machine, feeding the paper rolled by the firework tube rolling machine and simultaneously gluing, and cutting the paper after the paper is rolled into a firework tube with a preset size; drying the cut firework reel for later use;

d. selecting dry yellow mud, grinding into powder and screening; loading the screened yellow mud into one end of a firework winding drum by using a press machine; the length of the yellow mud section pressed into the firework winding drum is 1.8-2.3 cm;

e. carrying out viscose splicing on the outer wall of the firework winding drum pressed with yellow mud, and then carrying out basin combination threading; adding black powder into the threaded firework reel; and (4) capping the loaded firework winding drum by using glue.

2. The method for manufacturing fireworks with high safety according to claim 1, characterized in that the thickness of the paper is 0.4-1.2 mm, the flexible net is formed by interlacing the absorbent cotton yarn in a net shape, the diameter of the absorbent cotton yarn is 0.4-1.5 mm, and the side length of the absorbent cotton yarn in a single grid of the flexible net is 1.5-2.5 cm.

Technical Field

The invention relates to the technical field of fireworks, in particular to a method for manufacturing a firework with high safety.

Background

Fireworks are traditional products in China, are invented earlier by workers in China, and are often used in exuberant ceremonies or performances. The firework has a long history and a deep cultural foundation in China, and is a very favorite entertainment event for people in festive festivals.

Fireworks and firecrackers have similar structures, the structures of the fireworks and the firecrackers comprise black powder and powder fuse, and in order to achieve good performance effect, a large amount of powder for launching and exploding is filled in fireworks and display shells. Black powder or propellant powder is the main dangerous raw material for producing fireworks and crackers, and has higher danger in the processes of production, storage and transportation, so that accidents are easy to happen.

The propellant or gunpowder of the fireworks and crackers produced by the traditional method generally adopts a mode of using one-sulfur-two-nitrate-three-charcoal, namely, more than 70 percent of potassium nitrate, 10 percent of sulfur and the balance of charcoal, and a large amount of black smoke is generated during combustion, thereby bringing great hidden trouble to safety production. The firework structure and the firework production and manufacturing mode are closely related to the safety of the final finished product of fireworks, and the effort for improving the structural stability and the safety of the fireworks is the direction of continuous efforts of firework production enterprises.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a method for manufacturing fireworks with high safety.

The invention is realized by the following modes:

a method for manufacturing fireworks with high safety comprises the following steps:

a. selecting paper with uniform and smooth texture, blowing air to clean two sides of the selected paper, coating an adhesive layer on one side of the paper, and covering and bonding a flexible net on the adhesive layer;

b. drying the surface of the paper, which is bonded with the flexible net, and curling the dried paper into a paper cylinder for later use;

c. b, opening the paper tube manufactured in the step b and feeding the paper tube into a firework tube rolling machine, feeding the paper rolled by the firework tube rolling machine and simultaneously gluing, and cutting the paper after the paper is rolled into a firework tube with a preset size; drying the cut firework reel for later use;

d. selecting dry yellow mud, grinding into powder and screening; loading the screened yellow mud into one end of a firework winding drum by using a press machine; the length of the yellow mud segment pressed into the firework winding drum is 1.8-2.3 cm;

e. carrying out viscose splicing on the outer wall of the firework winding drum pressed with yellow mud, and then carrying out basin combination threading; adding black powder into the threaded firework reel; and (4) capping the loaded firework winding drum by using glue.

Furthermore, the thickness of the paper is 0.4-1.2 mm, the flexible net is formed by interweaving the absorbent cotton yarns in a net shape, the diameter of the absorbent cotton yarns is 0.4-1.5 mm, and the side length of the absorbent cotton yarns in a single grid of the flexible net is 1.5-2.5 cm.

The invention has the beneficial effects that: through cleaning and reinforcing the reel paper, paper one side covers the bonding through the viscose and has flexible net, and follow-up flexible net curls to the reel inside wall, can strengthen the structural strength of shaping reel uniformly, also has supplementary fixed effect to yellow mud and black powder in the section of thick bamboo for fireworks structure is more stable, the security is better.
