Apparatus for non-contact cleaning a paint spray tip

摘要

An apparatus for non-contact cleaning a paint spray tip of a spray gun. The apparatus includes a housing with a top and an opening formed in the top to receive the spray tip. At least one drier nozzle is fluidly connected to a source of compressed air so that discharge from the nozzle impinges upon and dries the spray tip. Similarly, at least one solvent nozzle is also attached to the housing around the opening and discharges solvent on the spray tip when positioned in the housing opening. One or more down flow nozzles are also mounted to the housing to create a downdraft through the housing opening to facilitate cleaning and drying of the spray gun spray tip. A heated fluid also flows through the housing in close proximity to the fluid passageways for the drier nozzle and solvent nozzle in order to heat both the drier nozzle air flow and solvent flow to facilitate cleaning of the spray tip.

主权项

1. A non-contact apparatus for cleaning a paint spray tip of a spray gun comprising:
a housing having a top and an opening in said top dimensioned to receive the spray tip such that the spray tip does not contact said housing, at least one drier nozzle attached to said housing so that a discharge from said at least one drier nozzle impinges the spray tip, said at least one drier nozzle fluidly connected through an air supply passageway to a source of pressurized air, at least one solvent nozzle attached to said housing and oriented to discharge solvent on the spray tip when positioned in said housing opening, said solvent nozzle fluidly connected through a solvent passageway to a source of solvent, at least one down flow nozzle adapted for connection with a source of pressurized air, said at least one down flow nozzle positioned in said housing at a position spaced from said top of said housing and oriented to discharge air in a direction away from said housing opening, said housing having a heater fluid passageway in close proximity to said solvent passageway and said air supply passageway, said heater fluid passageway fluidly connected to a source of heated fluid.
