Problems solved by technology

[0003] However, the existing integral molding composite fireworks materials are mixed with various fillers such as kaolin, and the pulp only plays the role of reinforcing ribs, and its structural strength is not high. When it exceeds, the finished product may crack; and it will cause the product to be too heavy, which will bring inconvenience to the product transportation and limit the finished product specification; at the same time, it is difficult to fully recycle the existing products, increasing the pressure on environmental protection

Embodiment Construction

[0023] Taking the production of 99 rounds of combined fireworks as an example, the method for making the integrally formed combined fireworks includes the following steps:

[0024] 1. Shredded paper: the waste paper is dry crushed by a shredder and passed through a 5-8mm sieve;

[0025] 2. Ingredients: First put 11kg of tapioca starch and 44kg of boiled water into the container according to the ratio and mix them thoroughly, then add crushed

[0026] 16kg of paper and 3kg of talcum powder, stir well with a mixer;

[0027] 3. Divide the material into the mold: According to the product specification, separate 18.5kg of the reconciled material and put it into the mold to heat and foam. Use high-temperature heat conduction oil to heat at a heating temperature of 270°C. At the same time, the hydraulic press applies 5Mpa to the mold cover to keep The time is 15 minutes, the product is dried and shaped, and the mold is demoulded. At this time, the weight of the finished product is a...

Abstract

The invention discloses an integrally formed composite firework and a production method thereof. It mainly uses shredded paper, tapioca starch and water as raw materials, and is foamed and molded. The components and weight / number ratio of the raw materials are: shredded paper 14-18 9-12 parts of tapioca starch, 42-46 parts of water, and 1-5 parts of talcum powder. The beneficial effects are: single component, uniform internal structure, high structural strength of the finished product, strong pressure resistance, good formability, and unlimited specifications of the finished product; the surface finish of the inner wall of the finished product launching cavity is high, the launch resistance is small, and the launch height of the same dose is larger , saving gunpowder, good economy and safety; the inner diameter of the firing chamber is standard, the height is uniform, and the follow-up operations such as charging are convenient, suitable for standardized and mechanized production; it can be fully recycled at low cost and has good environmental protection performance; the production process is simplified and simplified. Improve production efficiency and save labor.

Description

technical field [0001] The invention relates to a combined firework and a manufacturing method thereof, in particular to a combined firework whose launch tube is integrally formed at one time and a manufacturing method thereof. Background technique [0002] According to the traditional manual process, the production of combined fireworks requires dozens of processes from paper cutting to finished product, such as paper cutting, gluing, rollers, edge trimming, drying, bottoming, arranging into strips, drilling, arranging, assembling basin etc. Production efficiency is low, and product specifications are difficult to standardize. Under the social background of increasing labor costs, in the prior art, the combined fireworks formed by the launch tube as a whole has partially replaced the traditional craft. The multiple launch tubes (also known as outer tubes) of the combined fireworks are molded as a whole, which greatly improves the production efficiency. [0003] However, ...
