Technical Field

The invention relates to a combined firework.

Background

According to the definition of GB 19593-2015, the combined firework is a product formed by combining two or more small fireworks, spraying fireworks and spitting beads with the same type or different types of fireworks. In the combined fireworks, a single-row cylinder body formed by connecting a plurality of fireworks paper cylinders is called as a cylinder row; the tube rows are laminated and assembled to form the combined basin.

In normal setting off, each tube row and each firework paper tube in the tube row are set off one by one according to the lead connection sequence. However, in the prior art, the combination fireworks are easy to have the phenomenon of fire crossing: namely, the gunpowder and the effect pieces in each firework paper tube are not sequentially ignited and launched by a firing cable according to a designed firing program, but two or more firework paper tubes in the same tube row or different tube rows are launched almost simultaneously, so that the firing effect is completely destroyed. Moreover, the faster the firing frequency (rhythm) of each firework paper tube is, the smaller the radial size of the firework paper tube is, the higher the probability of occurrence of a fire cross is.

Meanwhile, a certain standard distance is kept between the front part, the rear part, the left part and the right part of the firework paper tube of the combined firework product, which is favorable for setting off safety, so that a plurality of combined firework products with the distance exist in the market, and the requirement of the distance is more a mandatory standard of the countries such as the United states.

Meanwhile, the combined fireworks can be divided into upright products and special-shaped products according to the distribution postures of the firework paper tubes, in the upright products, the axis of each firework paper tube is vertical to the horizontal plane, and each firework paper tube is in an upright posture; in the combined firework product with the special-shaped distribution, the axes of all or part of the firework paper cylinders are not perpendicular to the horizontal plane, the firework paper cylinders are not in an upright state but in a left-inclined state and/or a right-inclined state, and the combination of the firework paper cylinders in different inclined states can form products such as a fan shape, a W shape, a V shape and the like. The special-shaped products are difficult to process and slow to produce, a large number of orders can not be completed on time every year, and factories can only receive orders according to production capacity.

In actual production, when the interval special-shaped combined firework product needs to be processed, the manual production process is complex:

1. the method comprises the following steps that glue is manually brushed on a bottom paperboard, paper tubes are placed and adhered one by one according to a set interval and a set posture, the paper tubes can be moved for subsequent processing after the glue is solidified for 2-4 hours after being placed, and the lower end edge of the bottom paperboard is bent towards the side of the paper tubes to avoid fire crossing. Because of manual work, there may be a deviation in the position of the cylinder of each paper tube, and after being launched aloft, the deviation is amplified to affect the effect of firing.

2. Because the cylinder body is not well positioned, the whole long lead wire cannot be used for connecting the lead wire holes of the paper cylinders of the whole cylinder row in series. Two lead holes can be drilled out on the paper tube one by one and small sections of leads are planted for fire transfer connection, and the whole safety lead needs to be installed for standby use as fire transfer due to low fire transfer reliability, so that fire cutoff is prevented.

3. And (3) sealing treatment for preventing fire cross: sealing the lead hole area by using kraft gummed paper, wherein the kraft gummed paper can be effectively sealed only by flattening and pinching; and then adhering and covering the upper surface paper board, and winding and sealing the bottom paper board and the surface paper board by using tin foil paper. The manufacture of one cylinder row is completed.

4. The tube rows are separated by battens to form intervals among the rows, the tube rows are assembled and molded in a laminated mode, and then the ends of the leads among the tube rows are connected in a fire transmission mode (commonly called surrounding leading) to complete basin assembly. Wherein the surrounding and guiding part is also smoothed out and pinched by kraft paper to be effectively closed.

5. The paper tube is filled with pyrotechnic compositions, such as propellant powder, effect powder (piece), etc., and the fire cross hidden trouble caused by the spilled medicament is avoided when the medicament is filled. The fixed bottom plate is arranged to be used as a base body for bearing the recoil of launching, and then the side plate, the face paper and the like are arranged to complete packaging.

The production process has high requirements on production staff, so that only part of specific staff which can be qualified is often selected to carry out the work in practice, but even if the specific staff is limited by the characteristics of manual labor, the phenomenon of fire cross cannot be avoided.

Therefore, for the combined fireworks, the production work efficiency of products with traditional structures is low, the labor intensity is high, the production cost is high, and the production quality is difficult to guarantee.

Preferably, the glue guide paper board is fixed below the lower positioning paper board in an adhesive manner, a plurality of strip-shaped glue guide grooves are formed in the glue guide paper board, the number of the glue guide grooves corresponds to the number of rows of the lower positioning holes, and the bottom end openings of the lower positioning holes in each row are located in the same glue guide groove. Preferably, the upper positioning hole for positioning the upper paperboard and/or the lower positioning hole for positioning the lower paperboard and/or the glue guiding groove for guiding the glue paperboard are punch-formed structures. Preferably, the firework paper tube is in interference fit with the upper positioning hole and/or the lower positioning hole through which the firework paper tube passes. The combined firework is integrally of a paper structure, is good in environmental protection property and easy to recycle, is good in adhesiveness, is easy to form a closed structure to prevent fire crossing, is small in density, high in structural strength, low in cost and easy to process.

Preferably, the fire wire of each row of firework paper cylinders is a complete long wire.

Preferably, the preparation method of the spaced special-shaped combined firework comprises the following steps:

preparing a material A: manufacturing an upper positioning hole on the positioning upper paperboard, manufacturing a lower positioning hole on the positioning lower paperboard, and manufacturing a glue guiding groove on the glue guiding paperboard; a lead hole penetrating through the tube body is formed at the lower end of the firework paper tube; the manufacturing mode is preferably a stamping mode.

B, arranging a glue guide groove: pasting the glue guiding paper board below the positioning lower paper board, wherein the bottom end opening of each row of lower positioning holes is positioned in the same glue guiding groove;

c, serially connecting the firework paper tube: inserting a complete long lead into the lead holes of the firework paper tubes; the plurality of firework paper tubes can be firework paper tubes forming one tube row or a plurality of tube rows.

D, installing a firework paper tube: after the serial connection, the upper end of the firework paper tube is inserted into the upper positioning hole of the upper positioning paper plate, and the lower end of the firework paper tube is inserted into the lower positioning hole corresponding to the lower positioning paper plate;

The order of the above steps is not limited to the above order, for example, the step B may be interchanged with the step C and/or the step D; the material preparation can also be adjusted according to the requirement; the effect is not affected.

In the method, if the whole combined firework is connected in series by using the long lead wire, the step of surrounding the lead wire is not needed, but the firework paper tube is too large in quantity and is inconvenient to be connected in series by using the long lead wire. Furthermore, a surrounding glue guiding groove is arranged on the glue guiding paper board corresponding to the connecting part and communicated with the glue guiding groove. Facilitating a better sealing of the connection. Preferably, when the firework paper tubes are connected in series, a complete long lead is inserted into the transition tube, then the transition tube is inserted into the lead holes of the plurality of firework paper tubes, the position of the long lead is located again, and the transition tube is drawn out, so that the long lead is inserted into the lead holes of the plurality of firework paper tubes.

According to our summary, the occurrence of cross-fire is based on several reasons: 1. sparking between the barrel rows or within the barrel rows; 2. after the pyrotechnic composition is ignited, flame is ejected from a gap between the lead hole and the lead to cause fire crossing; 3. powder leakage to the fuse area during powder filling results in fire spread. In the method, the lead hole of each firework paper tube and the fire transmission lead thereof are positioned in the glue guide groove with a certain depth and are sealed by glue; meanwhile, the upper positioning plate blocks the falling of pyrotechnic compositions, and even if pyrotechnic compositions are scattered in filling, the pyrotechnic compositions cannot fall to the lead connecting part below to cause fire crossing hidden troubles. Therefore, the phenomenon of fire cross can be effectively avoided.
