Embodiment 1

[0041] A production process of fireworks and firecrackers, comprising the following steps:

[0042] A1. Material selection:

[0043] Choose paper that is even and smooth;

[0044] A2, glued reel:

[0045] The selected paper is conveyed into the reel machine through the conveyor belt. The speed of the reel machine is 1400 rpm, and the paper is glued while reeling, and the paper is cut after the glue is applied;

[0046] A3. Drying:

[0047] Expose the cut paper to sunlight or dry it for later use;

[0048] A4. Soil selection:

[0049] Select yellow mud with high viscosity, dry it, grind it into powder, and sieve it;

[0050] A5. Canister:

[0051] Use a press to pack the sieved yellow mud into the reel cut off in step A2, and the distance between the yellow mud and the bottom of the reel is 1cm;

[0052] A6, Viscose threading:

[0053] Combine the outer wall of the pressed mud drum with glue, and then thread the pots. The size of the pots is a square of 10×10;

[0054]...

Embodiment 2

[0064] On the basis of Example 1, in step A3, the sunlight exposure time is 7 days, if the required dryness is not achieved, the reel will be deformed, have poor hardness, or even be damaged.

Embodiment 3

[0066] On the basis of Example 1, in step A3, when drying, the temperature of the drying chamber is 60 degrees, and the drying time is 8 hours. If the drying degree that meets the requirements is not reached, the reel will be deformed and the hardness will be poor. Even broken.

Abstract

The invention relates to the technical field of preparation of fireworks and crackers, in particular to a production process of the fireworks and crackers. The production process of the fireworks andcrackers comprises the following steps that A1, materials are selected, specifically, smooth paper with uniform texture is selected; A2, gluing and coiling are performed, specifically, the selected paper is conveyed into a coiling machine through a conveying belt, the rotation speed of the coiling machine is 1400 turns each minute, the paper is coated with glue while being coiled, and the paper iscut off after being coated with the glue; A3, drying is performed, specifically, the cut-off paper is irradiated in sun or dried for standby; A4, mud selection is performed, specifically, yellow mudwith high viscidity is selected, ground into powder after being dried, and then screened; A5, charging into coils is performed, specifically, the screened yellow mud is charged into the coils cut in the step A2 through a pressure machine; A6, gluing and threading are performed; A7, the coils are irradiated in sun to be dried, specifically, the fireworks and crackers subjected to pot threading in the step A6 are aired in a sunlight greenhouse, and the moisture content of the dried yellow mud is 10%; A8, black powder is added; and A9, the fireworks and crackers are boxed and delivered. The fireworks and crackers produced according to the method are not prone to deformation and small in pollution to the environment.

Description

technical field [0001] The invention relates to the technical field of fireworks and firecrackers preparation, in particular to a production process of fireworks and firecrackers. Background technique [0002] Black powder or propellant is the main dangerous raw material for the production of fireworks and firecrackers. It is more dangerous in the process of production, storage and transportation, and is extremely prone to accidents. However, the propellant or propellant of traditionally produced fireworks and firecrackers generally uses one Sulfur, dinitrate, and charcoal, by the way. That is, potassium nitrate is more than 70%, sulfur is 10%, and the rest is charcoal, which will produce a large amount of black smoke when burned, and bring great hidden dangers to safe production. [0003] In the fireworks industry, pyrotechnic powder generally refers to the reducing agent or the mixture of oxidizing agent and reducing agent used in fireworks and firecrackers. Such as the ...
