Abstract
The utility model discloses a large festive firework shell made of bioplastic, which comprises an upper half spherical shell and a lower half spherical shell, wherein a circle of concave-convex grooves having buckling function and a plurality of glue injection holes are molded at the edge connecting part of the upper half spherical shell; a circle of concave-convex grooves buckling with the upper half spherical shell correspondingly are molded at the edge connecting part of the lower half spherical shell; a timing wire conduit is molded at the bottom center of the shell. In the utility model, after two half spherical shells are filled with fireworks and gunpowder materials and tightly buckled by virtue of the concave-convex grooves, adhesives are filled through the glue injection holes so as to solidify upper and lower half spheres to form a firm sphere; and the upper spherical shell and the lower spherical shell are respectively formed by integrated injection molding. The large festive fireworks shell made of bioplastic has the advantages of simplifying production processes, improving fireworks output and quality, realizing program-controlled automatic unmanned operation, and ensuring safe production.
Description
Technical field
The utility model relates to a kind of cartridge case of firework body device, more particularly, is about the cartridge case of firework body device with the biodegradation material plastotype.
Background technology
At present, the display shell housing of selling on the market is in two hemispherical solid fiberboard shells after the powder charge, and outer sticky several layers of paper parcel forms, and sticky paper does not wait for sticky 5 layers-20 layers according to the display shell size.Process: solid fiberboard is cut out, stamp, gluing hot-forming, boring, install blasting fuse pipe, cotton yarn twine, varnish fixing, the base ring gummed paper is fixed, primer, papering, bake procedure surplus (stick with paste which floor promptly bake do once) etc. ten.Substantially by manual operations, to take a lot of work, time-consuming, production efficiency is low, and potential safety hazard is many, and especially papery cartridge case of firework humidity resistance is poor, and overcast and rainy production is influenced, long-term storage moisture-sensitive and losing efficacy.Papery case fragmentation cacophonize, decibel exceeds standard.
Utility model patent---plastic housing display shell in addition, the patent No. 85202712.Propose petroleum base chemical synthesis plastics-production display shell housings such as a kind of ABS of using engineering plastics, Merlon, polystyrene, polypropylene,, strengthen explosive force, could use owing to need specially join different bursting charges.And its material belongs to the non-degradable speciality, and the fractionlet soil that is scattered in fried back can't reclaim contaminated environment.After being subjected to thermal explosion, the plastics pernicious gases such as producing dioxin that is heated, contaminated air.Extensively used, do not meet the use standard by fireworks and firecrackers industry, tissue, enterprise's refusal.Its type shape is to adopt upper and lower hemispheres to insert to connect, and gluing again after the powder charge can cause glue contact with medicinal powder like this, is difficult to operation, and glue consumption big, glue not firm.Simultaneously, glue also can make gunpowder make moist, and influences quality.
Summary of the invention
The purpose of this utility model is that design a kind ofly can overcome above-mentioned shortcoming, but provides a kind of and utilize natural degradation, the structure uniqueness, the assembly process of biological plastics injection mo(u)lding to simplify, the display shell housing of safety in production.
The purpose of this utility model is to be achieved by following technical proposals.
Biological plastics display shell housing of the present utility model comprises upper hemispherical shell and lower hemisphere shell two parts composition, tongue and groove and several hole for injecting glue of a circle fastening effect moulded in junction, described upper hemispherical shell edge, a circle and the corresponding tongue and groove that fastens of upper hemispherical shell are moulded in junction, described lower hemisphere shell edge, regularly conduit has been moulded by bottom centre, the two halves spherical shell is packed into behind the fireworks powder material, after utilizing tongue and groove to fasten closely, inject adhesive by hole for injecting glue, reinforce the synthetic firm spheroid of upper and lower hemispheres, the integral molded plastic moulding respectively of described spherical shell up and down.
The integral molded plastic moulding respectively of described upper and lower hemispherical Shell body and function biodegradation material, the tongue and groove that described upper and lower hemisphere connects, closing up after the powder charge is the self-locking fastening.Described hole for injecting glue is located at junction, two hemispheres edge, is used to inject glue, glue flow to along the gap of tongue and groove around the bead gluing firmly, making the upper and lower hemispheres secure bond is one.
The utility model advantage compared with prior art is:
Plastotype arbitrarily: according to various fireworks ball quality and assembling needs, can be with base, ball holder, regularly injection mo(u)lding in the lump on spheroid such as conduit, standard is unified, and directly powder charge need not layer by layer hand process such as adhesive tape twines, bake.Simplify production process, improve output and quality;
2, the fireworks and firecrackers quality is good: the spherical shell quality is even, and firecracker is gentle in voice, flower type circle, attractive in appearance, crushed material natural degradation, environmental protection;
3, simplify assembly process, raising output: adopt one-body molded spheroid, can realize machine assembling, automated procedures control, and stop artificial assembling, guarantee safety.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model
Fig. 2 is a structure installation diagram of the present utility model
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
In the drawings, the display shell housing is made up of two parts: episphere housing and lower semisphere housing.The tongue and groove 3 of a circle fastening effect is moulded in episphere housing 4 bead junctions, and branches such as circumference are provided with several hole for injecting glue 2, and regularly conduit 1 has been moulded in lower semisphere housing 6 bottoms, moulds the tongue and groove 5 that a circle and episphere tongue and groove are interlocked in the bead junction.Hole for injecting glue quantity is pressed spherical shell girth difference, determines the quantity of hole for injecting glue.3 cun spherical shells with diameter 68mm are example, and hole for injecting glue 5-6, hole for injecting glue is 2 * 3mm.Pack in two hemispheres housing up and down behind the fireworks powder material, tongue and groove 3,5 fastens and closely becomes a spheroid up and down.Inject adhesive by each hole for injecting glue, as 101 glue.Adhesive flows to bead along the tongue and groove gap gluing all around firmly.
Claims (4)
