Abstract
The present invention relates to the field of fireworks technology. The ball plastic casing includes the top ball casing, down launching chemical tube and the balancing tail rod muff connected to the connecting tube. The ball casing has edge notches and has different shapes. The present invention is simple in structure and the one single blowing formation process has high production efficiency, low cost and high fireworks assembling quality.
Description
The invention belongs to the fireworks technical field, relate to a kind of blown plastic casing for ball fireworks rocket.
Spherical fireworks rocket is a kind of display shell, the fireworks carrier can be emitted to high-altitude more than 50 meters, and then the high altitude fireworks that explodes and bloom.The manufacturing more complicated of ball fireworks rocket, particularly the manufacturing of shell is numerous and diverse especially, introduced the conventional method of producing ball fireworks bullet shell in " firework safety production technique " book: fire works display projectile shell is made of strawboard or yellow plate paper, cut a sheet of paper earlier, strike out required form with forming press again, then according to the fire works display projectile shell desired thickness of different size, open with 3-5 and to coat paste, overlap mutually, put into the hydraulic press mould inner pressure and make type, owing in the mould electrothermal furnace is housed, can be in the die mould process with the spherical shell heat drying, cut after the pressure and accomplish hemisphere, two hemisphere are lumped together the formation spheroid, be cut into the papering that is fit to the peripheral stickup of spheroid with brown paper, in papering, be coated with one deck paste, closely paste around the spheroid periphery, successively by behind vertical spheroid stickup one deck, the staggered one deck of pasting of horizontal again spheroid.According to the difference of fireworks display effect and the difference of fireworks display kind, generally to thicken 2-5mm, every stickup layer 2-3 rolls spheroid on the plate face, papering is cemented, and shine, paste once more, after paste is good, that spherical shell is fully dry, after spherical shell is carried out, also spherical shell and propelling charge cartridge case to be bonded together with brown paper.From above introduction as can be known, make ball fireworks rocket envelope process process complexity in this way, time-consuming, efficient is low, the production cost height, and assembly quality is low.
The objective of the invention is to provide a kind of one-shot forming, can produce in enormous quantities fast, production efficiency height, cost is low, assembly quality is high, simple and efficient to handle blown plastic casing for ball fireworks rocket.
The objective of the invention is to realize with the following methods.This blown plastic casing for ball fireworks rocket, the propelling charge cartridge case tube connector that comprises top ball-type shell, bottom, balance foot piece cover on the propelling charge cartridge case tube connector, whole casing adopts plastics as a whole with the blow moulding moulding, the ball-type shell is made up of geometric figure, and the edge between the geometric figure is recessed limit groove.The utility model will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 front view of the present invention;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the partial enlarged drawing of Fig. 1;
Fig. 4 is user mode figure of the present invention.
Among the figure:
1-ball-type shell 2-propelling charge cartridge case tube connector 3-balance foot piece cover
4-geometric figure 5-limit groove 6-effect medicine and filling auxiliary material
The 7-emission is protected with black powder 8-safety lead-in wire 9-and is drawn cover
10-balance foot piece 11-propelling charge cartridge case
The technology that the present invention utilizes plastic product to produce uses blow molding process to make the ball fireworks rocket shell, makes appearance looks elegant, the whole casing one-shot forming, and manufacturing process is greatly simplified.Geometric figure (4) on the shell (1) is mixed by a kind of geometric figure or several geometric figure and forms, and geometric figure can be circle, ellipse, triangle, quadrangle, pentagon, hexagon.Because the edge between the geometric figure all is the thin-walled that falls in, form the stressed weak link of shell, geometric figure is evenly distributed on the shell, and then weak link also is evenly distributed on the shell with geometric edge.Can make ball fireworks rocket lift-off explosion time like this, spherical shell can be evenly to ftractureing (split in the place in weak link) all around, and firework display effect can be better.
Making ball fireworks rocket with the present invention can enhance productivity and assembly quality greatly.As shown in Figure 4, earlier with the effect medicine and fill auxiliary material (6) and pack in the ball-type shell (1), balance foot piece (10) is inserted in the balance foot piece cover (3), again emission is pressed in the propelling charge cartridge case (11) with black powder (7), and the safe lead-in wire (8) of packing into, propelling charge cartridge case (11) is injected in the tube connector (2) by force, emission is contacted with effect medicine and filling auxiliary material (6) with black powder (7).Such ball fireworks rocket just assembling has been finished, therefore the present invention is guaranteeing that the body lift-off blooms under the prerequisite of modeling effect, overcome traditional complicated technology manufacturing process by 2 half paper shell spheroid bodies, production efficiency is improved greatly, and help carrying out mechanization production, reduce the whole production cost.
