Description

Technical Field

[0001] The utility model belongs to the field of welding wire production, in particular to a welding wire raw material feeding device. Background Art

[0002] In the production of welding wire drawing, the wire rod coil formed by winding the raw material for welding wire drawing, i.e. the wire rod, must first be placed on the unwinding rack, and then the wire rod is pulled out from the top of the unwinding rack to carry out the welding wire drawing production.

[0003] At present, the unloading rack for placing the wire rod coil is composed of a bottom plate and several columns arranged in the circumferential direction. The several columns enclose a cylindrical space for housing the wire rod coil. During production, the wire rod coil is placed on the bottom plate, and several columns are passed through the wire rod coil. At this time, the wire rod coil is supported by the bottom plate, and is limited by several columns in the circumferential direction to prevent the wire rod from being disordered when it is discharged.

[0004] However, since the diameter of the space enclosed by several columns is smaller than the inner diameter of the wire rod coil, that is, there is a gap between the inner diameter of the wire rod coil and the columns, the wire rod guiding property is poor. When the wire rod is pulled out, it often shakes and even becomes tangled, resulting in the wire rod being unable to be smoothly output, affecting the subsequent welding wire drawing production.
