Automatic punching slicer of firework barrel

Abstract

The invention provides an automatic punching slicer of a firework barrel. The automatic punching slicer is characterized by comprising a bracket and a rack, wherein the bracket is provided with a reeling shaft and a paper roll is arranged on the reeling shaft; the rack is provided with a firework barrel clamping and conveying mechanism, a punching slicing die switching mechanism, a paper sheet punching slicing mechanism and a paper sheet clamping and conveying mechanism. All actions of punching a small hole, punching a round paper sheet, pressing the round paper sheet into the firework barrel and automatically conveying the firework barrel are automatically finished by a machine, and a worker only needs to put the firework barrel on a conveyor belt, so that the labor intensity of the worker is low and the operation is convenient; two mechanisms for punching the small hole and punching the round paper sheet are combined together, and a small round hole is formed in the left side of a template and a large round hole is formed in the right side of the template; only if the template is driven by a template pushing oil cylinder to move leftward and rightward, small hole punching or round paper sheet punching can be switched; and the left-right movement of the template has high switching precision and errors are not generated, so that the punched small hole can be located in the central position of the round paper sheet all the time, and the quality of the product is guaranteed.

Description

technical field [0001] The invention relates to the processing arrangement of the fireworks tube, in particular to an automatic punching and slicing machine for the fireworks tube. Background technique [0002] The structure of the fireworks tube is generally divided into two types, one is a combination of multiple single tubes, and the other is to directly mold the entire fireworks tube with a mold. There are multiple launch holes in the firework tube, and each launch hole There are upper and lower layers of circular paper, the lower circular paper has small holes for fire transmission, the upper circular paper has no small holes, the upper and lower circular paper divides the firing holes into three layers, and the bottom layer is equipped with a small amount of gunpowder for fire transmission , and connected with the lead wire, used to launch the inner tube (that is, the tube with pyrotechnic effect), and the inner tube is set in the middle layer. The existing technology...

Problems solved by technology

The existing technology is to first punch out circular paper sheets through a punching machine, and punch small holes for fire transmission on the circular paper sheets, and then manually put the circular paper sheets into the firing holes one by one, so that not only the labor intensity of workers is high, but also the labor cost High, if the round paper is placed unevenly, workers have to take it out and place it again, and the work efficiency is very low

Therefore, someone applied for the Chinese invention patent ZL201310021358.8, the patent name is "a combined firework automatic paper pressing device", the patent divides the small hole for punching fire and the punching round paper into the left automatic punching mechanism and The circular paper on the right is used to make the press-in mechanism. In this structure, the automatic punching mechanism first punches small holes on the paper. After punching, the paper is pulled by the paper pulling assembly, so that the paper with the small holes is moved to the circular paper to make the press. In the position of the mechanism, the press-in mechanism made of a round paper punches out the round paper and presses the round paper into the fireworks tube. The disadvantage of this structure is that the automatic punching mechanism and the round paper are made into the press-in mechanism. Set separately, first punch small holes, and then pull the paper with small holes to move to the position of the circular paper making press-in mechanism. Due to the different tightness of the paper roll on the paper pulling component, it is easy to cause the paper pulling distance when pulling the paper Too much or too little error, the error will cause the small hole to deviate from the center of the round paper, even if the error is small, but the accumulation will make the small hole stamped in the later stage gradually deviate more and more, which will lead to ignition At this time, the ignition of the bottom layer gunpowder cannot be transmitted to the middle layer through the small hole, and the lead wire of the inner cylinder of the middle layer cannot be ignited, so that the inner cylinder becomes a squib after firing.
