Positioning device and positioning method for inserting lead in firework paper drum

Abstract

The invention provides a positioning device and a positioning method for inserting a lead in a firework paper drum. The positioning device comprises a paper drum bracket for placing the firework paper drum; at least two positioning rollers are fixed above the paper drum bracket, and are horizontally arranged and fixed on a roller seat; and the roller seat is connected on a first driving mechanism, and is driven to do up-down movement relative to the paper drum bracket by the first driving mechanism. The positioning method comprises the following steps that: (1) the firework paper drum rolls to the lower parts of the positioning rollers along the paper drum bracket; (2) the first driving mechanism drives the positioning rollers to move downwards, so that the firework paper drum is clamped between the positioning rollers; and (3) a second driving mechanism drives the positioning clamping groove to move downwards, so that the firework paper drum is clamped in the positioning clamping groove. The positioning device can realize automation, the direction offset problem of the firework paper drum is avoided by prepositioning of the positioning roller, accurate positioning can be carried out by the positioning clamping groove, and the positioning effect is good.

Description

technical field

[0001] The invention relates to a mechanized production method and equipment of fireworks, in particular to a positioning device and a positioning method for the threading wire of a fireworks paper tube. Background technique

[0002] In the manufacturing process of fireworks, inserting lead wires is one of the important processes, and the quality of inserting lead wires directly affects the quality and production efficiency of fireworks. At present, most of the fireworks threading is carried out by manual simple devices, which have the following defects: 1. The position deviation of the threading hole punched out is large, and the quality of the hole is unstable; 2. The lead wire may be reinserted or missed. The quality of the insertion is poor, the efficiency is low, and large-scale production cannot be formed, and the production cost of the enterprise is high; 3. In the process of insertion, it is easy to cause lead wire interference and string fire, which ...
