Drilling and lead inserting system for assembling firework

Abstract

The invention discloses a drilling and lead inserting system for assembling a firework. The system comprises a needle bar, a lead feeding device, a numerical control system and a driving and transmission system, wherein the needle bar can move upwards and downwards in a reciprocating way; the lower end of the needle bar is provided with an n-shaped drilling and lead inserting device which consists of two parallel drilling needles; a large movable tongue and a small movable tongue are arranged between the two drilling needles; the lead feeding device consists of at least one lead supply wheel and a lead guide groove; and the driving and transmission system comprises at least one driving motor and a plurality of transmission devices, is connected with an electromagnet of the numerical control system and is used for driving and controlling every component of the drilling and lead inserting system to run synchronously. The drilling and lead inserting system is arranged above a firecrackerbarrel conveying passageway, can be used for accurately finishing a series of works such as lead supply, lead cutting, lead inserting and the like, has high degree of automation, high working efficiency and working reliability; and drilling and lead inserting are finished synchronously, and the lead inserting quality of is effectively ensured.

Description

technical field [0001] The invention relates to a firework machine for assembling and molding a plurality of firework tubes, in particular to a mechanical device for punching holes in the firework tubes and inserting lead wires. Background technique [0002] In the process of making fireworks, when gluing multiple fireworks tubes into a whole, it is necessary to punch two holes on each firework tube as the lead-in hole and the connection hole, and insert them between two adjacent firework tubes. Overfire fuse, that is, insert a “∏” or inverted “U” shaped overfire fuse into the lead wire outlet hole of the previous firework tube and the lead wire outlet hole of the next firework tube to realize the fire transmission function. At present, this process is all done manually in actual production, which not only has low work efficiency and high labor intensity, but also cannot guarantee the quality requirements. [0003] CN2823970 discloses a fireworks assembling machine. A table...

Problems solved by technology

[0004] However, the technical maturity of this technical solution is not high, and it is difficult to be applied in actual production

The punching and insertion work are completed in two steps by the double-headed hole punching device and the "Π"-shaped lead wire insertion device, which not only increases the equipment and process, but also makes the insertion and insertion very difficult, and the success rate of insertion is low. At the same time, the above-mentioned documents only mentioned the concept of "∏-shaped lead wire insertion device" and lacked corresponding technical solutions. However, as a core problem of fireworks assembly, lead wire insertion involves supplying, cutting, Stop a series of problems such as lead supply, lead replacement, and lead insertion. Even the lead lead involves how to shape a soft straight lead into a "∏" shape and insert it into two adjacent lead holes.
