Definitions

  • the invention relates to a drain box for a doctor blade chamber of a rotary printing press.
  • a color chamber according to the prior art is for example from the DE 197 34 910 A1 known in which the doctor blade chamber of a flexographic printing machine is described.
  • the printing ink is applied to the printing cylinder by means of an anilox roller, which in turn is inked with the aid of a doctor blade chamber.
  • the surface of the anilox roller has a regular grid of flat cells, which are filled with printing ink when the relevant peripheral section of the anilox roller moves through the ink chamber of the doctor blade chamber filled with printing ink.
  • the ink chamber is part of the doctor blade chamber and is delimited in the longitudinal direction by two doctor blades and on the end faces by two sealing elements.
  • the doctor blades and the sealing elements of the sealing bodies can be adjusted to the ink application roller, so that the ink sealing roller, the doctor blades, the doctor chamber body and the sealing bodies seal the channel-like recess to the outside, so that an interior is created which is closed.
  • the doctor blade chamber body is provided with an ink supply which is often arranged in the center.
  • color sequences are generally also provided in order to maintain a color cycle can. These color sequences, via which the printing ink, which is inevitably enriched with air in the printing operation, can be removed, are arranged in the end regions of the interior or the channel-like recess.
  • the object of the present invention is therefore to reduce the cleaning costs of a doctor blade chamber of a rotary printing press.
  • Fig. 1 shows a perspective view of an end face of a doctor blade chamber 101 with the drain box cartridge 102 according to the invention.
  • the doctor blade chamber 101 has two doctor blades 103 and 104 in a known manner adjacent first partition (covered by the sealing element 106) and a second partition 108 is delimited.
  • the sealing element 106 is in turn held on the outside by a pivotable fixing plate 107.
  • Fig. 2 shows the process of inserting the drainbox cartridge according to the invention into the front of the doctor chamber Fig. 1 .
  • the reference symbols not shown correspond to the reference symbols Fig. 1 , so that in relation to the above description according to Fig. 1 is referred.
