Pre-drilling device for leading wire enclosure for cylinder combination of combined firework

Abstract

The invention discloses a pre-drilling device for leading wire enclosure for cylinder combination of a combined firework. The pre-drilling device comprises a first machine head and a second machine head which are arranged on the two sides of the integrated blocky firework, wherein the first machine head and the second machine head are of the same structure and are arranged in a bilaterally symmetrical mode. Each machine head comprises round hole inserting needles which are arranged in parallel with one above another, and needle heads of the round hole inserting needles face the integrated blocky firework; needle holders of the round hole inserting needles are arranged on a left guide rod and a right guide rod, the left guide rod and the right guide rod are arranged on an upper movable base plate and a lower movable base plate, round needle driving cylinders are arranged on the upper movable base plate and the lower movable base plate, and the needle holders of the round hole inserting needles are driven by the round needle driving cylinder in a reciprocating mode in the left-right direction; the upper movable base plate and the lower movable base plate are arranged on an upper guide rod and a lower guide rod, and the upper movable base plate and the lower movable base plate are driven by a base plate driving cylinder reciprocating mode in the vertical direction. According to the pre-drilling device, the success rate of wire insertion during leading wire enclosure is effectively increased; meanwhile, the device meets the requirements for the working target and the working environment during leading wire enclosure, processing efficiency is high, equipment is small in size and compact, and adjustment is convenient.

Description

technical field [0001] The invention relates to a punching device used in the enclosing process of combined fireworks group pots. Background technique [0002] In the production process of combined fireworks, there is a process commonly known as "pot grouping". The process is called continuous lead; then the multiple rows of fireworks tubes that have been connected are glued together to form a block, and the two adjacent rows of fireworks tubes are drilled to insert the overfire fuse. This process is called encirclement. [0003] The mechanized production equipment of combined fireworks is usually called "pot assembly machine" or "firework assembly machine" in the industry. The punching and insertion device is an important key process part of this type of equipment. Hole insertion work, the completed work is: in the above-mentioned fireworks production process, after a plurality of fireworks tubes are combined into a row, two holes are punched on each firework tube as the l...

AI Technical Summary

Problems solved by technology

The disadvantage of the existing punching and inserting mechanism is that the punching needle is provided with a guide groove, and the cross section of the needle body is a U-shaped structure, and a U-shaped tongue-shaped incision will be cut on the paper fireworks tube. In general, the notch will be pressed down to form a lead hole, but in some cases, if the U-shaped tongue is not pressed enough or rebounds after being pressed down, it will hinder the entry of the lead wire and reduce the insertion success rate
