A leadless festive cannon and its manufacturing process

Abstract

The invention discloses a leadless festival firecracker and a manufacturing technology thereof. The leadless festival firecracker is characterized by comprising a one-piece frame, single bodies provided with tail pipes, and connecting bars, and the multiple single bodies provided with the tail pipes are connected and combined freely into an integral plate through the connecting bars and the one-piece frame; each single body provided with the tail pipe comprises an upper pipe body provided with a bottom, and the burning charge tail pipe used for replacing a lead, wherein the upper pipe body provided with the bottom and the burning charge tail pipe are integrated, a blasting hole which is integrally communicated with an open inner cavity of the upper pipe body provided with the bottom in a penetrating mode is formed in the center of the burning charge tail pipe, an ignition port is formed in the lower end of the burning charge tail pipe, the blasting hole of the burning charge tail pipe is filled / poured with ignition charges, and the open inner cavity of the upper pipe body provided with the bottom is filled with firework effect charges. The manufacturing technology comprises the steps of design and manufacturing of a special die, compression molding, ignition charge pouring, effect charge filling, charge drying, and finished product packaging. The leadless festival firecracker has the advantages that the structure is simple, no lead is needed, the manufacturing technology is simple, variable combined set-off modes are available, and the set-off effects are novel.

Description

technical field [0001] The invention belongs to the field of fireworks processing and production, and in particular relates to a leadless festive firecracker with a leadless structure and lead installation process and a manufacturing process thereof. Background technique [0002] In the prior art, there are many toy fireworks products, but they are all inseparable from the ignition lead wire and lead wire installation process. In terms of product molding and production, they are all single-piece processing and molding and single-piece installation of the ignition lead wire. Wrapping paper is single-wrapped and packaged. This traditional production process has many processes, long production hours, low work efficiency, high cost, difficult to control product quality, and great safety hazards. Moreover, the discharge method is also a single ignition discharge. It takes a long time and is fun. monotonous. At present, there are many products in the market, such as ice cannon fi...
