Display shell with three-dimensional shape firework pattern and manufacturing method thereof

Abstract

The invention relates to a display shell with a three-dimensional shape firework pattern and a manufacturing method thereof. The display shell comprises a guide ribbon, a paper shell of the display shell and a display shell body which is arranged in the paper shell of the display shell. The display shell is characterized in that: the display shell body is divided into concentric spherical ring layers from a sphere center to outside; the three-dimensional shape is pre-arranged in the spherical ring layers; a sphere center body, with the shortest semidiameter from the internal three-dimensional shape contour to the sphere center, is filled with black explosive of cottonseeds or rice hulls; all the spherical ring layers from the sphere center body to the paper shell of the display shell are divided into an external small display shell layer, a middle black explosive layer and an internal kraft paper layer; a small luminous colored display shell or a small smoke bomb is intersected with the external three-dimensional shape contour, while a blank cartridge or a small non-luminous colored display shell is not intersected with the external three-dimensional shape contour; and the fuse of the small luminous colored display shell or the small smoke bomb is buried in the middle black explosive layer. When the display shells are exploded in the sky, the expectant three-dimensional shape firework patterns appear so as to bring the perfect visual enjoyment to people.

Description

technical field [0001] The invention relates to a firework bomb with a three-dimensional modeling fireworks pattern and a manufacturing method thereof. Background technique [0002] At present, the traditional spherical fireworks bombs are carefully arranged with cottonseed or rice husk black explosives and bright beads or other fireworks parts such as small fireworks bombs, smoke agents, etc., so that the overall arrangement maintains its chemical and physical properties when the fireworks bombs are detonated in the air. spherical symmetry, so that the pre-installed bright beads or other fireworks components are projected in an ideal spherical or approximate spherical shape, forming chrysanthemum-shaped, peony-shaped, coconut-shaped and other fireworks patterns at high altitudes, as well as simple shapes such as rings, smiling faces, and stars. Plane firework pattern, can't make any preset three-dimensional three-dimensional modeling firework pattern. Contents of the inve...
