Description
Technical field
The present invention relates to fireworks, relate in particular to remote control and light and the Combined fireworks of reading.
Background technology
As everyone knows, the paper bobbin that tradition fireworks are connected by multiple lead-in wires assembles, it generally all will be through system cylinder, press mud at the bottom of, insert and draw, fill the operation such as nitre and bright pearl, sealing, assembling and encapsulation, not only have that operation is various, production efficiency is low, production cost is high, the normalization of product or standard is not high and poor working environment, labour intensity are large, be unfavorable for the drawbacks such as mechanical production line operation, and to consume a large amount of paper woods and earth, cause the waste of ecological resources, go back contaminated environment simultaneously, destroy ecological. For these problems, have people to make monoblock type fireworks tube with waste materials by mold pressing, the wire lead slot being all connected with nitre medicine is set in cylinder bottom, then 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, at the bottom of not wanting mud yet, can save paper stock and earth, can not produce environmental pollution, fireworks tube can reuse, but in use also there is following problem in it: the one, and need to prepare different moulds for the fireworks of different size and suppress different fireworks, mould structure is also more complicated, and die cost cost is high, and it is many that press is also wanted, otherwise to often exchange mould, reduce production efficiency; The 2nd, once there be a cylinder damaged on fireworks tube, will cause fireworks tube entirety to scrap, increase cost, reclaim, collect and storage also not quite convenient, then be lead-in wire also trouble in tandem, sometimes also can the fiery phenomenon of leaded string, the quality problems such as cause that fireworks can not be seted off, affect firework product quality; That firework display does not also have the function that identity is followed the tracks of, thereby can leave potential safety hazard, even leaves opportunity to offender along with there will be some artificially to carry out the phenomenon generation of unlawful activities with nitre medicine in fireworks production and application again.
Summary of the invention
For the existing problem of fireworks in above-mentioned prior art, the invention provides a kind of by combination of monomers, and can realize the Combined fireworks of remote control ignition and reading.
