Definitions

  • JP 2010- 284 892 A, JP 2010- 143 060 A, JP 2010- 201 874 A and US 2016/ 0271 950 A1 disclose a suction device for ink mist in an inkjet printing system, the suction device being located downstream of a bottleneck after the printing unit in the transport direction .
  • the disadvantage here is that there is a possibility of contamination for the recording medium and the printing system between the printing unit and the suction device.
  • a method for sucking off ink mist in an inkjet printing device having a printing unit for printing on a front side of a recording medium moved through the printing unit along a transport direction.
  • the method comprises guiding the record carrier along the transport direction through a mechanical constriction arranged over the front side of the record carrier.
  • the method also includes causing a gas flow that runs in the constriction against the direction of transport over the printed front side of the recording medium.
  • the method also includes sucking off ink mist from the printed front side of the recording medium in a suction area which is arranged in front of the constriction in relation to the transport direction. Due to the fact that the constriction has an extension of less than 25 mm in the direction of transport, the gas stream or the flushing air can effectively prevent ink mist from penetrating into the area of the constriction.
  • the amount of ink mist 170 that is transported into the drying unit 150 can be reduced by the constriction 202 and by the flushing air 204 .
  • the ink mist 170 is sucked off by a suction unit 205, which is arranged in front of the constriction 202.
  • the suction unit 205 can be arranged in a flexible manner in spatial proximity or also relatively far away from the constriction 202 . A particularly efficient and comprehensive suction in front of the constriction 202 can thus be made possible.

Abstract

L'invention concerne un dispositif d'aspiration (200) pour un dispositif d'impression à jet d'encre (100). Ledit dispositif d'aspiration est conçu pour guider un support d'enregistrement imprimé (120) le long d'une direction de transport (1) par un étranglement (202) avec un flux de gaz contrarotatif (204) afin de pouvoir aspirer de manière efficace et complète le brouillard d'encre (170) dans la direction de transport (1) en amont de l'étranglement (202).
