Combined firework inner barrel packaged with multiple layers of paper pulp

Abstract

The invention relates to combined firework inner barrels, in particular to a combined firework inner barrel packaged with multiple layers of paper pulp. The firework inner barrel comprises an inner barrel fuse, an inner barrel fuse end mud bottom, an inner barrel body, bright beads and at least one group of paper pulp. The inner barrel fuse end mud bottom is arranged at one end of the inner barrelbody. The inner barrel fuse is arranged on the inner barrel fuse end mud bottom. The inner barrel body is filled with the bright beads and unpacking chemicals. The bright beads and the unpacking chemicals are covered with a perlite powder layer. At least two layers of paper pulp are arranged at the other end of the inner barrel body in a press fit manner, wherein at least one layer of paper pulpis used to seal the inner diameter part of the inner barrel body and is provided with a guide hole, at least one layer of paper pulp for sealing the guide hole is arranged between the paper pulp withthe guide hole and the perlite powder layer, and the paper pulp for sealing the inner diameter part of the barrel body is arranged as the uppermost one of all the layers of paper pulp. According to the combined firework inner barrel packaged with the multiple layers of paper pulp, the multiple layers of paper pulp are adopted instead of a traditional mud bottom or a manner of using fuse fixing agents to seal a barrel, the step of barrel sealing is completed after the layers of paper pulp are pressed in, and the time waiting for drying is not needed.

Description

technical field [0001] The invention relates to a combined fireworks inner tube, in particular to a combined fireworks inner tube packaged with multi-layer paper. Background technique [0002] At present, the sealing of the inner cylinder of combined fireworks mainly relies on manual use of simple tools to make the mud bottom or fixation agent. The labor intensity of the workers is huge, and the staff are in harsh and dangerous production environments all the year round; mistakes in manual sealing are inevitable. Therefore, product quality is difficult to be guaranteed. Because the raw materials of the product are inherently dangerous, the gunpowder and bright beads in the unsealed inner cylinder are all exposed, which poses a great safety hazard and seriously threatens the personal and property safety of the people. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the existing combined fireworks inner tube mainly relying on ma...
