Description

Can repeatedly load environment protection firework launcher

Technical field

This utility model relates to fireworks technical field, particularly with regard to a kind of launcher that can repeatedly load environment protection firework.

Background technology

It is known that, tradition fireworks are assembled by the paper bobbin of multiple lead-in wire series connection, it generally will pass through at the bottom of cylinder processed, pressure mud, insert and draw, fill the operation such as nitre and bright pearl, sealing, assembling and encapsulation, do not only exist that operation is various, production efficiency is low, production cost is high, the standardization of product or standard is not high and poor working environment, labor intensity is big, be unfavorable for the drawbacks such as mechanical production line operation, and to consume substantial amounts of paper wood and earth, cause the waste of ecological resources, go back contaminated environment simultaneously, destroy ecology. For these problems, having people to make monoblock type fireworks tube with waste materials by mold pressing, then arrange the wire lead slot being all connected with nitre medicine bottom cylinder, by lead placement in wire lead slot, after filling nitre medicine and bright pearl, encapsulation forms monoblock type fireworks again. Although the fireworks of this structure are without paper web, do not want at the bottom of mud, can save paper stock and earth yet. But it in use there is problems: one is that fireworks tube is not easy to recycling, the fireworks tube abandoned is to environment, two is that the fireworks for different size need to prepare different moulds to suppress different fireworks, mould structure is also more complicated, die cost cost is high, press also wants many, otherwise often to exchange mould, can reduce production efficiency; Two is once there be a cylinder damaged on fireworks tube, will result in fireworks tube entirety and scraps, and increases cost, reclaim, collect and storage also not quite convenient, then be lead-in wire in tandem also cumbersome, sometimes also can leaded string fire phenomenon, the quality problems such as cause that fireworks can not be seted off, affect firework product quality. In order to solve the problems referred to above, the applicant has applied for that (application number is 2014207992126) one does not need paper stock and earth, environmental pollution will not be produced, repeatable utilization, and a large amount of mould and lead-in wire can be saved, production cost can be reduced, improve the Combined fireworks unitarily formed by mold pressing of production efficiency. This Combined fireworks it be that the steam produced by firework display enters heating heating wire or direct thermal current in adjacent fireworks tube by air flue and lights this fireworks, so circulation carries out, but some problems in use also deposited by the launcher of filling Combined fireworks: one is after using a period of time, the upper and lower die holder of launcher owing to loading fireworks can deform, cause that the hot gas path formed by upper and lower die holder can leak gas, thus reducing thermal current pressure, and reduce steam amount, affect setting off of fireworks; Two is that steam road directly communicates with the launching tube inner chamber of bullet lower end, and such steam flow direction disperses, and mass rate of emission is slow; Three is it some times happens that thermal current is collaborated between adjacent transmission cylinder, causes and sets off and can not carry out according to the order of sequence, reduces firework display effect, even causes fireworks not set off.

Owing to fireworks launch tube is together in series one by one, high temperature gas flow is carried to realize igniting by air flue, set off one by one, if centre has one to leak gas due to air flue, will be affected itself, even affect remaining fireworks tube and can not set off, this is not allow existence during fireworks use, it is therefore necessary to launching tube (launcher) is solved, to guarantee that fireworks realize setting off continuously.

Utility model content

For the problem organized in above-mentioned prior art existing for fireworks launcher, this utility model provides one and has air flue sealant, it can be ensured that fireworks can be seted off continuously, can repeatedly load the launcher of fireworks.

The technical problems to be solved in the utility model is adopted the technical scheme that: the described environment protection firework launcher that can repeatedly load includes die shoe and upper bolster, described die shoe is arranged at intervals with supporting station, described supporting station is single, double or multiple rows of setting, described upper bolster is provided with the heavy stand hole matched with supporting station, being provided with between described upper bolster and die shoe can by the airway of supporting station concatenation connection, described airway is made up of air intake duct and exhaust duct, first supporting station side is provided with and can load igniting of igniter head, described airway periphery is correspondingly arranged on the sealing device that can be sealed by airway, seal groove that described sealing device includes being positioned on die shoe and be positioned on upper bolster and the sealing strip of seal groove can be embedded into.

This utility model is solve steam better to flow to dispersion, the problem that mass rate of emission is slow, the heavy stand hole of upper bolster is provided with backing plate, airway and launching tube lower end inner chamber are separated by described backing plate, and described backing plate is provided with air inlet and steam vent that airway two ends can be made to communicate with launching tube lower end inner chamber respectively.

It may happen that deform after the upper and lower die holder of described launcher uses certain time, described sealing device sealing can decline, cause collaborating to prevent thermal current from leaking, supporting station periphery on die shoe is provided with external seal groove, and the heavy stand hole periphery on upper bolster is provided with the external seal strip can being embedded in external seal groove.

This utility model can be provided with metal heating wire on supporting station, and described metal heating wire reaches more than 300 DEG C, and it can make the gun propellant combustion in inner core, and described metal heating wire is 0.1��0.2 millimeter, and described metal heating wire is with containing Ta₂O5 and Nb₂The tantalum niobium silk of O5 is made. Described igniter head red phosphorus or white phosphorus are made, and metal heating wire, near sub warhead lower end, utilizes thermal current to add thermometal heating wire to light sub warhead (inner core), and sub warhead is built with gunpowder and bright pearl etc. Also sub warhead can be lighted by direct thermal current.

Sub warhead in this utility model sets off rear repeatable loading head, and the present invention can form 25 (5 �� 5), 36 (6 �� 6), 64 (8 �� 8), 100 (10 �� 10) fireworks etc.; Or be the fireworks such as 20 (4 �� 5), 24 (4 �� 6), 48 (6 �� 8) of cuboid, 60 (6 �� 10), 80 (8 �� 10).

This utility model is owing to being provided with sealing device at thermal current airway periphery, not only the controlled air-flow that heats does not leak out and has enough thermal currents to carry out igniting and set off, and thermal current can be made to flow in an orderly manner, guarantee that fireworks are normally seted off, launcher compact conformation of the present invention, easily manufactured, lightweight and ruggedness are strong.

Advantage of the present utility model:

1, the repeatable utilization of described launcher, can save substantial amounts of paper wood and earth, be conducive to ecological resource protection,

2, firework display will not produce pollutant, is conducive to environmental conservation,

3, papery need not be used to go between, do the repeatable utilization of lead-in wire with metal heating wire, reduce lead-in wire cost, papery lead-in wire can be effectively prevented from and surprisingly burn the security incident brought,

4, can avoid papery lead-in wire that the problem that string fire brings occurs, improve firework product quality.
