Definitions

  • the invention relates to a powder cup spray gun and a spray coater with a powder cup spray gun suitable for spraying coating powder.
  • the powder storage container of these powder cup spray guns is located directly on the spray gun.
  • the powder reservoir which is also referred to below as a powder cup or in short as a cup, has a relatively small capacity.
  • the gun-shaped sprayer has a powder container that can be screwed on top of the gun head.
  • the pistol head has to top a countersink with an Inngewinde.
  • the powder container includes a connection piece with an external thread that matches the internal thread.
  • JP 6 320101 A is a powder spray gun for shell casting known.
  • the powder consisting of plastic is injected into a depression of a heated mold.
  • the powder is in a powder container at the back of the spray gun.
  • FIG. 1 is taken from the operating instructions and shows the cup gun D in a three-dimensional view.
  • the cup gun D is a manually operable powder spray gun with a powder reservoir cup H, which is screwed in the rear of the top of the gun D.
  • the cup gun D has for this purpose a screw thread J on.

  • the compressed air supply to the cup gun can be adjusted.
  • these cup guns have the Disadvantage that the color change can not be done fast enough.
  • the user must first carefully unscrew the storage cup from the gun. To do this, he holds the pistol with one hand and with his other hand he grasps the cup and unscrews it. As a rule, he will grasp the cup several times in order to unscrew it completely.
  • the encompassing is tricky, especially if there is still powder in the reservoir, because then there is a risk that the powder is spilled or trickles out of the outlet opening of the powder cup.
  • the compressed air supplied to the gun via the supply port is divided into a conveying air, a Tribo poverty (at the Tribopistolen) and a Zerstäuber Kunststoff (at the Corona gun), a metering air and an air for fluidizing the powder.
