Automatic lead inserting device of combined fireworks

Abstract

The invention discloses an automatic lead inserting device of combined fireworks. The device comprises a lead channel which is used for positioning and conveying leads, wherein the lead channel at least comprises components which are arranged at the two ends of the lead channel and restrain the leads. A lead conveying mechanism, a lead cutting mechanism and a lead inserting mechanism are sequentially distributed along the lead channel, a material disc which bears firework cylinder rows is correspondingly arranged below the lead inserting mechanism, and the device further comprises a mechanism which enables the lead inserting mechanism and the material disc to generate relative displacement. All the working mechanisms conduct coordination work according to the working procedure under the action of a control system. According to the device, automatic lead inserting machining of a brand-new lead structure with the reliable and accurate fire transferring and ignition can be achieved, the lead inserting fire connecting working between lead holes with any gap can be met, and the application range of automatic equipment on firework production is expanded. The machining precision is high, compared with existing equipment, the automatic lead inserting device greatly simplifies the number of the working mechanisms, meanwhile, the working stability is improved, the service life is prolonged, the manufacturing cost is reduced, and the use and maintenance are easy and convenient.

Description

technical field [0001] The invention relates to automatic processing equipment for combined fireworks, in particular to an automatic processing device for inserting a lead wire into a lead wire hole of a fireworks tube. Background technique [0002] Combined fireworks industry is also called ground fireworks or ground ceremony. Usually, several paper tubes are connected into a single row of paper tubes (referred to as tube row), and then lead holes are made on the paper tube, and the lead wires of each tube are installed in series, and several tube rows are assembled into shapes (such as rectangles, cylinders, Prism, fan-shaped body, etc.), and the lead wires of each cylinder row are installed in series, and the inner cavity of the paper tube is used to launch medicine and effect parts, which are ignited by the lead wires. [0003] The lead wire structure of the existing combined fireworks is to drill two lead wire holes in the side wall of each paper tube body, one is a fi...

AI Technical Summary

Problems solved by technology

The disadvantages of the existing lead wire structure are: first, the reliability of fire transmission and ignition is not strong, and the design of point-to-point relay fire transmission structure is difficult to completely prevent the occurrence of fire failure, especially the fire transmission in the inner cavity of the paper cylinder is more difficult. It is prone to failure; failure of any fire transfer point will lead to misfire phenomenon of the product, which not only leads to launch failure and affects the discharge effect, but also is very prone to safety accidents when ordinary consumers go to observe and deal with after misfiring

Second, in the traditional lead wire structure, it is necessary to cut the long continuous lead wire into multiple small segments for use, and the lead wire is made of gunpowder coated in the outer cladding, and the cutting destroys the gunpowder distribution in the inner cavity, which affects the fire transfer performance. It also caused an impact; at the same time, cutting the lead wire involves gunpowder, which is dangerous no matter manual or mechanical operation, and has a great safety hazard

Third, the traditional lead structure has complicated processing technology and low production efficiency

[0010] Due to the limitations of the above factors, the existing automatic assembly equipment for combined fireworks can only process products with the same lead hole spacing, and the adjustment of the spacing requires manual intervention or even replacement of the machine head; at the same time, due to the spacing, it cannot process products with an inner diameter smaller than 30mm paper tube

Considering only the application scope of the equipment, the technical maturity of these models also needs to be improved urgently
