Firecracker pouring leading line technology method

Abstract

The invention discloses a firecracker pouring leading line technology method that a bottom-sealed firecracker cake (1) is vertically fixed on a mold plate (3); a pouring and leading device is arranged in the axis direction of the firecracker cake; pouring and leading needles (5) correspond with the paper cylinders on the firecracker cake in number and position; the pouring leading line needles (5) can extend into the paper cylinders (4); and when the leading line slurry (9) in the pouring leading line needles flows into the inner walls of the paper cylinders in line shape under the pressure, the pouring leading line needles move from inside to outside till the pouring leading line needles move out of the firecracker cake, and the solidified line-shaped leading line slurry can be fixed on the inner walls of the paper cylinders to serve as the leading lines (2). According to the firecracker pouring leading line technology method, the leading lines are safe to make, the material consumption and waste are reduced, the making cost of the leading lines is reduced; and as the leading lines are uniform in size and correct in position, leading line breaking and splitting are avoided, the fire joining performance is excellent, and all the paper cylinders of the firecracker cake can be simultaneously poured and led once for all, the inserting leading line procedure is reduced, the inserting leading line efficiency of the firecrackers is improved, the inserting leading line cost is reduced, and the economic benefits are improved.

Description

technical field

[0001] The invention relates to a process method in which the wire paste is injected into the inner wall of the paper tube of the firecracker cake in a line shape, and the wire paste is dried and solidified to become a wire. Background technique

[0002] In traditional festivals, weddings, school promotions, building completions, store openings, and various celebrations, funerals, temple fairs and other activities, people often like to set off firecrackers to add joy and commemorate. As we all know, the production of firecrackers generally has to go through processes such as tube making, back sealing, insertion, charging, sealing, whipping and packaging. Among them, insertion is an important process. It directly affects the use effect and economic benefits of setting off firecrackers. Firecracker insertion refers to inserting the lead wire into the paper tube. The insertion method has changed from the traditional manual insertion to the current mechanical in...
