Description

The one-shot forming Combined fireworks and firecrackers cylindrical shell of built-in lead-in wire

Technical field

The utility model relates to a kind of combined barrel that loads firework medicine or firework effect power, is specially a kind of disposal molding Combined fireworks and firecrackers cylindrical shell of built-in lead-in wire.

Background technology

Combined firework is a kind of large-scale firework product that development in recent years is got up, when setting off because of it, possesses sound, light, the combination of multiple effect such as color and longer duration, the scene atmosphere, liven up very, it is a kind of firework product that fireworks party and celebrating Festival celebration Festival are extremely liked, producing this Combined fireworks and firecrackers is to adopt single paper web to tie up gluing combining, the periphery is again with yellow plate paper or brown paper parcel, the production process complexity of this cluster Combined fireworks and firecrackers, labour intensity is big especially and be used for the production of single paper web of Combined fireworks and firecrackers, the cost height, production efficiency is low, has many producers to adopt mechanical reel and machinery to suppress at the bottom of the mud at present, though this rotary machine and compacting clay bottom apparatus production efficiency height, but waste of material is big, and waste material is many, and cost is higher; The patent No. is 200420068147.6 Chinese utility model patent, though solved the traditional handicraft of producing the firework urceolus with paper preferably, its weak point is: can only produce firework external cylinder at the bottom of the single band, when making Combined fireworks and firecrackers, still need after manually with the gluing binding combination moulding of a plurality of band bill kept on file tubes, can load medicine, its assembling procedure complexity, labour intensity is big, and cost height, the requirement of incompatibility fireworks manufacturer modern production, the applicant has obtained " the Combined fireworks and firecrackers cylindrical shell of once-forming " that State Patent Office is authorized in first to file, overcome above-mentioned defective preferably, it is the significant innovation of Combined fireworks and firecrackers cylindrical shell, but in use still have weak point, mainly be that string fire lead-in wire installation serial connection is not convenient, therefore be necessary to be improved once more.

The utility model content

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides that a kind of production cost is low, in light weight, manufacture craft is simple, properties of product are stable, moisture resistance is good, the one-shot forming Combined fireworks and firecrackers cylindrical shell of the built-in lead-in wire of environmentally safe.

Technical solution of the present utility model is: a kind of one-shot forming Combined fireworks and firecrackers cylindrical shell of built-in lead-in wire, comprise a cavity, the tube chamber, the string fire hole, string fire lead-in wire, at the bottom of the tube cavity, uniformly in the described tube cavity be provided with several unlimited straight tubulars suitable for reading or be conical cylinder chamber down, be used to load firework propellant powder and effect power, tube chamber bottom centre is provided with the string fire hole, top at the bottom of the tube cavity and a tube chamber bottom centre go here and there fiery orifice end connecting portion and are built-in with a logical string fire lead-in wire, make string fire lead-in wire be communicated with serial connection along the center string fire hole of several bottoms, chambeies, this string fire lead-in wire spread geometry and order can be arranged according to the needs that Combined fireworks and firecrackers is seted off and be set to laterally or for vertically or be oblique; Being configured to plane or being the U-shaped shape of tube chamber bottom; The profile of tube cavity is square or for rectangle or for circular or for oval.

The utility model is because the disposable compression molding of employing built-in string fire lead-in wire is a composite entity structure, top at the bottom of the tube cavity is provided with a logical string fire lead-in wire with the fiery orifice end connecting portion of string and gangs up with the center string fire hole of each bottom, chamber and is connected, overcome repeatedly machine-shaping at the bottom of paper web in the existing public use technology and the mud, not water-fast protection against the tide, the easy loose defective that drops at the bottom of the mud, also simplified the Combined fireworks and firecrackers cylindrical shell and will make up gluing binding with a plurality of monotubulars, enclose paper, complicated procedures of forming such as serial connection lead-in wire, its advantage is: the Combined fireworks and firecrackers cylindrical shell is built-in with a logical string fire lead-in wire through the disposable integral compression molding in processing and fabricating, the multi-size standardization, medicine is loaded in suitable mechanization automatically, automatically encapsulation waits pipelining production, the production technology advantages of simple, excellent in cushion effect, water-fast moisture resistance is good, body is stable, mechanical performance and security performance meet the quality standard of country about the firework urceolus fully, production cost is low, alleviated labour intensity, its outer shape and specification size and tube chamber quantity can be arbitrary shape and size specification and needed tube chamber quantity according to the disposable compression molding of Combined fireworks and firecrackers needs, this cylindrical shell is to make with degradable mineral material in addition again, product is seted off and is used back chance water to degrade fully in two months, can satisfy the needs and the environmental requirement of firework manufacturer.
