Definitions

  • the invention relates to a device for coating objects with paints according to the preamble of claim 1.
  • an object for. B. a board with a conveyor to a paint application section, in which three or more spray nozzles are arranged at an angle of 90 ° - 120 ° to each other. These create a color veil that wets the surface of the object with color liquid. It is disadvantageous that after leaving the paint application section during the aftertreatment with distributor brushes, only a rough distribution of the sprayed-on paints takes place. A further intensive distribution with known distributor rollers does not prevent the paint from remaining unevenly distributed.
  • this device requires frequent replacement of the rollers, the bristles or surfaces of which quickly become hard as a result of the ink, which means a great deal of additional effort.
  • the invention has for its object to provide a coating device which no longer has the disadvantages mentioned above for coating and post-treatment of objects, with which the coating of objects is simplified and with which a previously unattainable high quality of the surface can be ensured.
  • the device should continue to be simple.
  • the device according to the invention consists of a housing 6, in front of which and after which or in which transport and support rollers for the objects to be coated, according to the figures, boards are arranged.
  • the coating material is therefore applied on the top by spraying and on the underside by contact application.
  • spraying with spray nozzles remains possible.
  • the smoothing or sizing area is separated from the paint application area by dividing walls 7 and 8 which extend from above and below to the surface but do not abut. These partitions can be flexible plastic curtains.
  • air nozzles 5 are arranged, which via slots formed by walls 11, a uniform air flow to the surface of the z. B. direct boards 1.
  • the air flow entering one of the air nozzles 5 is divided into an upper and a lower part, the upper being deflected at the end of the nozzle and thus a uniform air flow can also flow out at the end of the nozzle.
  • the interior 10 of the air nozzles 5 is thus divided by a partition 16 which is not continuous in its entire length.
  • the nozzles 5 have non-stick plates 12 on their outer sides, which are chamfered at their ends in such a way that an opening nozzle is created. There is advantageously no paint remaining on its outer tips, so that it is avoided that the nozzle slots slowly become clogged. At the narrowest point, even between the diaphragm walls 11, the exiting air flow blows any paint residues safely away.
  • the slot-side ends of the plates 12 have tips 13 which form an angle of approximately 30 ° -60 °, preferably approximately 45 °.
  • the inside of the housing like the individual components of the overall device which come into contact with the paint, has a non-stick coating, so that after the device has been switched off it is easy to clean.
  • the paint itself which is blown off as superfluous from the surfaces of the objects to be treated, is collected in a sump 17 and used again for application via a pump 18. So it is certainly prevented that color is consumed unnecessarily.
