Plasma torch for coating production

Abstract

The utility model relates to plasma torch technical field, and disclose a kind of plasma torch for coating preparation, including gun rod and fixedly installed in the gun rod side gun mouth, when using the device for spraying, coating can be heated to high temperature and quickly sprayed outwards by gun nozzle, when gun nozzle is sprayed, nitrogen filled in the air storehouse arranged in its inside will be heated expansion and push movable tube due to high temperature when spraying, movable tube slides to be wrapped in the inside of movable tube, movable tube is dark light-transmitting material, harmful light generated by spraying can be blocked by movable tube at this time, the plasma torch for coating preparation can be heated and expanded by nitrogen in air storehouse by high temperature generated when spraying in actual use, gas expansion pushes movable tube outwards and shields gun nozzle, harmful light generated by gun nozzle spraying can be effectively shielded, greatly reduce the harm to staff.
