Problems solved by technology

[0004] Different from the traditional hand-made process, this integral one-time molded combined fireworks is produced by mechanized equipment assembly line, but the following problems are prone to occur in this large-scale production process: when injecting multiple cylindrical cavities At the same time, when a circular piece of paper (commonly known as paper baba, whose function is to separate the pyrotechnics and effect parts built in the tubular cavity) is loaded, some circular pieces of paper are prone to rollover in the tubular cavity, etc. Need to manually check and correct one by one; resulting in a decrease in product production efficiency and an increase in production costs
At the same time, there are problems such as high technical difficulty and high equipment cost to eliminate the above problems by improving production equipment.
In particular, it should be noted that these problems may occur in any single barrel (one round or a tubular cavity), and the products produced by an assembly line per working day are often calculated in tens of thousands of rounds, so controlling production costs is also a must Consideration

Embodiment Construction

[0013] Referring to the accompanying drawings, which reflect a specific improved structure of the present invention, several tubular cavities 1 are evenly distributed in parallel on the combined firework body, the upper port 2 of the tubular cavity 1 is open, the lower port 3 is closed and a fire transmission hole 4 is provided, The tubular cavity 1 has a built-in launch pyrotechnic drug and effect parts. The upper port 2 of the tubular cavity 1 is a tapered port with a large upper part and a smaller lower part, with a height of 3-30mm. The diameter difference between the smaller bottom circles is between 0.2-6 mm, and in this example the smaller bottom circle coincides with the neck 5 . The tubular cavity connected to the lower bottom surface of the tapered port (that is, the neck 5 ) is a tapered cavity 6 with a large top and a small bottom. The cross-sectional diameter of the neck 5 is equal to the diameter of the circular paper sheet.

Abstract

The invention discloses an improvement structure for compression-molding combined fireworks. A combined firework body is and uniformly provided with a plurality of tubular cavities in parallel, the upper end opening of each tubular cavity is opened, the lower end of each tubular cavity is sealed and provided with a fire transferring hole, the interior of each tubular cavity is loaded with firework launching charge and an effect piece, and the upper end opening of each tubular cavity is a conical end opening which is provided with a large upper part and a small lower part. When a circular paper sheet enters each tubular cavity, the guide function is realized by the conical end opening with the large upper part and the small lower part, and then each circular paper sheet is naturally transited along the conical end opening in the downward moving process to reach the state that the circular paper sheet is concentric with each tubular cavity, so the circular paper sheet can maintain the horizontal state after being pressing and penetrated into each tubular cavity, and the problems of side tipping and the like are solved. The improvement structure has the advantages that the scheme is simple, the design is skillful, easy implementation is realized, and the cost is low.

Description

technical field [0001] The invention relates to an entertainment pyrotechnic product, especially a combined firework. Background technique [0002] According to the definitions of the national standards of the People's Republic of China GB10631-2004 "Fireworks and Firecrackers Safety and Quality" and GB19593-2004 "Fireworks and Firecrackers Combined Fireworks" and other normative documents, combined fireworks are fireworks products composed of multiple single tubes. A single barrel is called a shot. Traditional combination fireworks are assembled from multiple paper bobbins, which have disadvantages such as numerous processes, low production efficiency, and low standardization or standardization of products. [0003] In recent years, our company has developed a composite firework that is integrally molded at one time, and the slurry is molded into shape. The shape and structure of the molded body are similar to those of traditional combined fireworks, and the overall shape...
