Pre-drilling mechanism for combined firework pot combining machine

Abstract

The invention discloses a pre-drilling mechanism for a combined firework pot combining machine. The pre-drilling mechanism comprises two parallel hole drilling needles, wherein the tail parts of the two hole drilling needles are fixedly connected with the same linear reciprocating movement driving element, the needle points of the hole drilling needles face a firework tube to be processed, an included angle is formed between the axial line direction of the hole drilling needles and the vertical direction of the located reference plane of the firework tube to be processed, and the inclined angle is 10 to 30 degrees. The pre-drilling mechanism has the advantages that a hole drilling mechanism and a perforation hole inserting mechanism can be integrated on one station for completing the function action, the processing quality of pre-drilling and insertion guiding is effectively improved, the processing time is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a punching and inserting device for a combined fireworks pot machine. Background technique [0002] In the process of making combined fireworks, there is a process commonly known as "pot grouping". First, multiple fireworks tubes are combined into a row (called a tube row), and then two adjacent fireworks tubes are drilled to insert the overheating fuse ( This process is called continuous lead); then the multiple rows of fireworks tubes that have been connected are glued together to form a block, and holes are drilled on the adjacent two rows of fireworks tubes to insert the overfire fuse (this process is called encirclement) . [0003] The mechanized production of combined fireworks is an important issue in the upgrading of the fireworks industry. This type of equipment 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...

Problems solved by technology

[0005] The disadvantage of the existing perforating and inserting mechanism is that the perforating needle is provided with a guide groove, resulting in a U-shaped cross-section of the needle body (in this patent, for the sake of clarity, the perforating needle is defined as a U-shaped needle), A U-shaped tongue-shaped incision is cut on the fireworks tube, and the U-shaped tongue-shaped incision is generally pressed down to form a lead hole, but in some cases, the pressing stroke of the U-shaped tongue is not enough Or when there is rebound after pressing down, it will hinder the entry of the lead wire and reduce the success rate of insertion
