Firework paper tube, sealing mold and sealing method for firework paper tube, and effect tube of firework paper tube

Abstract

The present invention discloses a firework paper tube, comprising a tube body, one end of the tube body is open, and the other end of the tube body is provided with a bottom seal that is formed by extruding the tube body itself. The invention also discloses a sealing mold, comprising a male part and a female part, the male part includes a cylinder accessible into the tube body, one end of the cylinder is a forming end for the bottom seal, the female part has a forming socket mating with the forming end of the male part, and the female part can sleeve one end of the tube body to rotationally pressurize the tube body so that the end of the tube body forms the bottom seal. The forming socket includes a cylindrical segment and an arc segment, the inner wall of the arc segment is provided with a plurality of sector grooves, an apex of each sector groove is positioned at an apex of the arc segment, and the depth of every sector groove peripherally decreases from one end to the other end so that an arc ridge naturally forms between the adjacent sector grooves. The step of pressing fire clay is omitted, production efficiency is improved, water and soil loss due to yellow clay production is avoided, environment protection is benefited, pollution by firing wastes is reduced, and injury by droppings is avoided.

Description

technical field [0001] The invention relates to a firework paper tube sealing tool, a sealing method and a firework effect tube made of the paper tube, in particular to a firework paper tube, a sealing mold, a sealing method and the effect tube of the firework paper tube. Background technique [0002] At present, both ends of the fireworks paper tubes on the market are open, and the production of fireworks effect tubes by using the fireworks paper tubes with both ends open mainly includes the following steps: [0003] 1. Insert the lead wire on the center hole of the mold; [0004] 2. Put the paper tube with open ends on the mold; [0005] 3. Filled with yellow soil and pressurized fire mud as the bottom seal of the firework paper tube, also known as bottom mud. [0006] 4. Fill the inner tube with bright beads, [0007] 5. Fill the inner cylinder with explosives, [0008] 6. Fill the inner cylinder with fixation agent, [0009] 7. Do some tail medicine on the lead end....

AI Technical Summary

Problems solved by technology

[0010] Among them, inserting and pressing the yellow mud to the bottom of the firework paper tube as the bottom seal not only requires the pressing machinery for pressing the yellow mud to the inner tube and the inserting machinery, which increases the production cost; More time, affecting production efficiency and increasing labor costs

[0011] In addition, in the production process of today's potted fireworks, a large amount of yellow mud, stone powder, and soil powder need to be used, which not only causes water and soil erosion, destroys the ecological balance, but also has hard soil clods and solid particles after the fireworks are set off. Agent crystal blocks fall from a high altitude, destroying the environment and posing safety hazards
