A CLEANING MACHINE 3D FORM SURFACE OF FOOTWEAR SOLE

摘要

The present invention relates to a three dimensional (3D) surface cleaning machine of a footwear sole. Particularly, the present invention relates to a 3D surface cleaning machine of a footwear sole capable of reducing front-end processes of brush in footwear manufacturing processes and improving the quality of footwear by applying plasma cleaning to whole surfaces of the footwear sole designed 3D according to the shape of feet. The present invention comprises a transfer unit (10) for transferring a footwear sole (1); a plasma gun (21) having a spray nozzle (22) toward the surface of the footwear sole (1); a support (40) for placing the plasma gun (21) at a predetermined height to arrange the spray nozzle (22) apart from the surface of the footwear sole (1); a plasma cleaning unit (20) radiating plasma provided from a plasma generator (24) toward the surface of the footwear sole (1) through the spray nozzle (22); and a control unit (30) for controlling the operation of the transfer unit (10) and the plasma cleaning unit (20). The plasma cleaning unit (20) forms a spray path (221) formed at the end of the internal of the spray nozzle (22) of the plasma gun (21) to be inclined toward the axis direction of the spray nozzle (22). The present invention has a rotating unit (23) for rotating the spray nozzle (22), so that the 3D surface of the footwear sole can be cleaned by the plasma of which the spray direction is continuously converted according to the rotation of the spray nozzle (22).
