Description

Technical Field

[0001] The utility model relates to the technical field of welding wire processing, in particular to automatic welding wire powdering equipment. Background Art

[0002] Automatic welding wire powdering is a device used for welding wire processing. During the welding wire processing, in order to improve the quality and performance of the welding wire, it is often necessary to apply welding powder on the surface of the welding wire. However, most of the existing powdering devices spray powder from top to bottom. Only the top of the welding wire is sprayed with powder, and the bottom surface of the welding wire is not sprayed with powder, which can easily cause uneven powdering. Therefore, we designed an automatic welding wire powdering device. Utility Model Content
