Powder adding and conveying device for flux-cored wire

Abstract

The invention provides a powder adding and conveying device for a flux-cored wire, wherein the upper end of an enclosure is connected with a powder adding mechanism, the powder adding mechanism comprises a first material bin and a second material bin, the lower end of the first material bin is connected with the second material bin, a stirring shaft is arranged in the first material bin, a plurality of stirring blades are arranged on the stirring shaft, a powder quantity regulation hopper is arranged in the second material bin, a discharge port is formed in the bottom part of the second material bin to be communicated with the enclosure, a refining filtering port is formed in the lower end of the discharge port, a conveyor belt is arranged in the enclosure, a powder recovery box is arranged at the lowest part of the inclined surface of the enclosure, a quantitating plate is arranged on the top wall on the inner side of the enclosure, a powder loading plate is arranged right below on end of the conveyor belt, and the powder loading plate is fixed on the enclosure through a rockshaft. The powder adding and conveying device has the beneficial effects that the bottom part of the inclined surface of the enclosure is connected with the powder recovery box, the left powder is conveyed and recovered to the powder recovery box, the waste of the powder is avoided, the powder adding mechanism comprises the first material bin and the second material bin, the powder can be evenly stirred, the quantity of the added powder is also regulated, and the quantitative powder adding is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of welding material manufacturing and processing, and in particular relates to a powder feeding and conveying device for flux-cored welding wire. Background technique [0002] Flux-cored welding wire is a new type of welding material that has developed rapidly in recent years and has been widely used in industrially developed countries. Flux-cored wire has obvious advantages, mainly to change the intermittent welding process into a continuous production mode, thereby reducing the number of welding joints, improving the quality of welds, improving production efficiency and saving energy. Flux-cored welding wire is also called tubular welding wire. By adjusting the type and proportion of flux-cored additives, various welding materials for different purposes can be conveniently designed. Among them, its alloy composition can be adjusted flexibly, and it is widely used in various types of welding. in technology...

Problems solved by technology

However, the powder feeding device for flux-cored welding wire usually uses a conveyor belt to feed the semi-finished welding wire into the welding wire. During the process of conveying and dividing, some powder will remain in the conveying device and cannot be recovered in time. These powders contain metal components. The dust scattered into the air not only affects the health of the staff, but also the machine is likely to cause safety hazards when encountering high temperature or open flames, endangering personal safety; Uniformity, affecting the processing effect of flux cored wire
