Abstract

The invention discloses a hemispherical shell punching device for small spherical fireworks shells, which comprises a reel for unrolling self-adhesive paper rolls, a lower winding mechanism for winding self-adhesive surface paper, and an upper winding mechanism for winding self-adhesive bottom paper Rolling mechanism; between the reel and the lower winding mechanism: the self-adhesive surface paper is placed on the worktable with the adhesive side up, and the hemispheres are arranged in sequence above the horizontally stretched self-adhesive surface paper The shell blanking mechanism and the hemispherical shell punching mechanism can automatically complete the drilling process of the small fireworks shell hemispherical shell, which is reliable in work, high in processing efficiency and guaranteed in punching quality.

Description

technical field [0001] The invention relates to a production equipment for small spherical fireworks shells. Background technique [0002] Small fireworks bombs refer to the products that can burst out various light colors, flower patterns or other effects after the projectile body is launched from the launch tube (single tube, including special launch tube) to high altitude or water area when it is set off. According to the shape and structure of the projectile, small fireworks shells are divided into two types: spherical and cylindrical, and their manufacturing techniques are different. What the present invention relates to is the processing of spherical small fireworks shells. The structure and effect of small spherical shells are similar to those of large shells, but the specifications are much smaller. According to the current national standard, the inner diameter of the launching tube of small shells should not be greater than 76mm. The production process of small fir...
