Patent ID: 8312833

Claim:
A pneumatic nozzle for roller coating, comprising: a machine; a rotating power source disposed on one side of the machine; a workpiece to be coated arranged and fixed on the rotating power source; a horizontal guide rail having a first end and a second end, the first end fixedly coupled to the machine; a horizontal sliding seat displaceably coupled between the first and second ends of the horizontal guide rail; a vertical guide rail having an end extending transversely from the horizontal sliding seat, the end of the vertical guide rail fixedly coupled to the horizontal sliding seat; a vertical sliding seat is displaceably coupled to the vertical guide rail; a high-pressure pneumatic nozzle disposed on the vertical sliding seat to proximally correspond to the workpiece fixed on the rotating power source for ejecting high pressure gas onto the workpiece providing a substantially smoothened coating of coating material on the workpiece; and a material supply nozzle corresponding to the workpiece fixed on the rotating power source and disposed on the machine; wherein displacing the horizontal sliding seat along the horizontal guide rail concertly displaces the vertical guide rail, the vertical sliding seat and the high-pressure pneumatic nozzle.
