Spaced special-shaped combined firework and preparation method thereof

Abstract

The invention discloses a spaced special-shaped combined firework and a preparation method thereof. A plurality of upper positioning holes are distributed in a positioning upper paper board at intervals, a plurality of lower positioning holes are distributed in a positioning lower paper board at intervals, a glue guide groove is fixedly formed in the lower surface of the positioning lower paper board, and the upper positioning holes and the lower positioning holes are the same in number and corresponding in position; and each firework paper tube penetrates through one upper positioning hole and one corresponding lower positioning hole, the bottom end of each firework paper tube is inserted into the glue guide groove, a fuse hole of each firework paper tube and a fire transfer fuse of eachfirework paper tube are located in the glue guide groove, and the glue guide groove is filled with glue. According to the combined firework, on the basis that the production process is simplified, andthe labor intensity and the labor precision are reduced, the phenomenon that flames flee out can be effectively eradicated; the posture adjustment of the paper tubes and the spacing arrangement between the tubes are convenient and quick to carry out; good environmental protection is achieved, recovery is easy to carry out, adhesiveness is good, a sealed structure is easily to form so as to prevent the flames from fleeing out, the density is small, the structural strength is high, the cost is low and processing is easy to carry out; and a bottom plate does not need to be additionally arranged,and the process is further simplified.

Description

technical field [0001] The invention relates to a combined firework. Background technique [0002] According to the definition of GB 19593-2015, combined fireworks are products composed of two or more small fireworks, spray flowers, and spit beads of the same or different types of fireworks. In combined fireworks, a single row of cylinders connected by several fireworks paper tubes is called a tube row; several tube rows are then stacked and assembled to form a group basin. [0003] During normal setting off, each tube row and each firework paper tube in the tube row are all fired one by one row by row in sequence according to the lead wire connection sequence. However, in the prior art, combined fireworks are prone to cross-fire phenomenon: that is, the gunpowder and effect parts in each firework paper tube are not sequentially ignited and fired by the fuse according to the designed discharge procedure, but two firework in the same tube row or different tube rows appear. ...

AI Technical Summary

Problems solved by technology

Because it is manual work, there may be deviations in the position of each paper tube. After launching to high altitude, this deviation will be magnified and affect the discharge effect.

[0008] 2. Because the cylinder body is not well positioned, it is not possible to use the entire long lead wire to connect the lead holes of the entire cylinder row of paper tubes in series

[0012] The above-mentioned production process has high requirements for production employees, so in practice, only some qualified employees can be selected to do the job, but even so, limited by the characteristics of manual labor, it still cannot prevent the occurrence of cross-fire

[0013] Therefore, for this type of combined fireworks, the production efficiency of traditional structural products is low, the labor intensity is high, the production cost is high, and the production quality is difficult to guarantee
