SPRAY COATING DEVICE FOR SPRAYING COATING MATERIAL IMPROVING EFFICIENCY RELATING TO SPRAY FLOW, COATING QUALITY AND COATING AMOUNT

摘要

PURPOSE: A spray coating device for spraying a coating powder is provided to improve an efficiency relating to a spray flow, a coating quality and a coating amount with a small forming air amount during a unit time. CONSTITUTION: The spray coating device for spraying a coating material(6) comprises a nozzle(4) for injecting the coating material; a forming air outlet(10) with a plurality of holes(14) which form a spray flow; and a spray beam(8); and/or a surrounding air perforating hole(50) for perforating and inspiring the surrounding air from a radial direction between the outlet(4) and holes(14) by an inspiration effect of a forming air flow(11).
