Problems solved by technology

The disadvantages are that the process is complicated, the assembly is troublesome, and the production efficiency is low, so that the enterprise has a large production cost; at the same time, because each fireworks effect tube is processed and formed separately, the drug weight, density, and the paper tube and the nozzle are not enough. To avoid the existence of individual differences, it is difficult to achieve uniformity when the assembled subtitle pattern fireworks products are set off, which will affect the product effect

Embodiment 1

[0020] Embodiment 1; See attached figure 1 , 2 , 4, reflect a kind of preferred concrete structure of the present invention, be used for assembling the pyrotechnic drug bar 8 of subtitle pattern fireworks, elongate strip shape, comprise the flexible fire-proof outer cladding layer 2 that silk braiding forms, the flexible fire-proof flame-retardant layer 3 that aluminum foil paper forms , and the outermost flame-retardant paint coating layer 4, which wraps the pyrotechnic effect drug 1 inside. Along the longitudinal direction of the pyrotechnic drug strip 8, a number of fire spray holes 5 arranged in a line are evenly distributed, and the holes penetrate the outer cladding layer 2, the flame-retardant layer 3, and the coating layer 4; the quick fuse 9 and the pyrotechnic drug strip 8 are arranged side by side, and the pyrotechnic effect medicine 1 is connected to the fast lead wire 9 through each flame-spraying hole 5, that is, the butt joint of the small holes on the flame-sp...

Embodiment 2

[0022] Example 2: see Figure 4 The difference from the above-mentioned embodiment 1 is that the flexible fire-proof and flame-retardant layer 12 made of aluminum foil is arranged between the pyrotechnic effect drug 11 and the flexible fire-proof outer coating 13 . Its flame retardant performance is better. During processing, it is necessary to insert aluminum foil paper while weaving the flexible fireproof outer cladding 13 .

Embodiment 3

[0023] Embodiment 3: see Figure 5 , the difference from the above-mentioned embodiment 2 is that the rapid fuse 29 is placed in the pyrotechnic effect drug 21 . The pyrotechnic effect drug 21 is also wrapped with a fire-resistant flame-retardant layer 22, a flexible fire-resistant outer cladding layer 23 and a flame-retardant paint coating layer 24.

Abstract

The invention discloses a firework gunpowder strip for assembling a caption pattern firework, which comprises a flexible wrapping layer. Fireproofing treatment is carried out on the flexible wrapping layer, and gunpowder with the effect of the firework is wrapped in the flexible wrapping layer. A plurality of fire spraying holes which are arrayed in line are uniformly distributed on the wrapping layer along the longitudinal direction of the wrapping layer. The gunpowder with the effect of the firework is in multipoint connection with a quick lead wire. As the firework gunpowder strip is a product formed in one step and adopts unified standards in specifications and quality, time, colors and the like of firework pictures when in ignition are neat and uniform; as large quantities of working procedures are reduced in the assembling link, the production process is simple and the operation is convenient; moreover, the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the field of subtitle pattern fireworks, in particular to a component for assembling subtitle pattern fireworks. Background technique [0002] At present, there is a kind of subtitle pattern fireworks, which can present subtitles or patterns according to the user's needs when it is set off, and the discharge effect is rich and colorful. In the prior art, fireworks with subtitle patterns are mainly composed of fireworks effect tubes, which are also called "subtitle heads", "subtitle tubes", etc., and are filled with pyrotechnic effect medicines, and radially arranged on the side walls of the fireworks effect tubes. There are firework injection holes, and there are two connection positioning holes at the head and tail ends of the effect cylinder. The tail end of the effect cylinder and the head end of the other effect cylinder are connected to the positioning holes with a connecting line, so as to connect multiple effect cylinder...
