Definitions

  • the invention has for its object to provide a doctor blade ink unit of this type, which has wear-free lateral boundaries, in which consequently no abrasion parts can be stored in the cups of the anilox roller, and which is simple.
  • a chamber doctor blade In the exemplary embodiment shown, which is intended for use in an offset printing press, a chamber doctor blade, generally designated 1, is provided.
  • the chambered doctor blade 1 comprises a U-shaped base body 2, two side walls 3 and two doctor blades 4, 5.
  • the two doctor blades 4, 5 can each be fixed by means of a clamping bar 6, 7 and only schematically indicated screws 8.
  • An ink tray 9 is provided below the chambered doctor blade 1. The means for fixing these parts on the printing press and for ink supply are not shown, they result from the applications mentioned at the beginning.
  • the chamber doctor blade 1 can be adjusted with the two doctor blades 4, 5 against an anilox roller 10.
  • the doctor blade 4 scrapes off the excess ink supplied in the direction of rotation of the anilox roller 10 indicated by the arrow a, while the doctor blade 5 closes the chamber doctor blade 1 at the bottom.
  • the inside 14 of the area 11 directly adjoins the inside 15 of the side wall 3, but, as shown in FIG. 4, is bevelled by an acute angle ⁇ with respect to the latter.
  • the outer side 16 of the area 11 abuts an oblique end face 17 of the wall 3 approximately at right angles, so that the outer side 16 is set back inwards with respect to the outer side 18 of the wall 3.
  • the area 11 is further provided on its upper side with a bevel 19 which forms an acute angle with the upper side 20 of the side wall 3.
  • a wedge-shaped gap 21 thus results between the doctor blade 4 and the bevel 19.
  • the greatest height of this wedge-shaped gap in the region of the outer end of the doctor blade 4 is at least 0.1 mm. This bevel ensures that the doctor blade 4 can bend slightly resiliently when it is applied to the anilox roller 10.
  • drain plate 22 On each outside 18 and thus also on the lateral outside of the doctor blade 4 there is a drain plate 22.
  • the drain plate 22 extends at one end at least up to the end faces of the doctor blade 4 and at the other end to just above the ink tray 9.
  • the drain plate 22 is connected to the associated side wall 3 by screws 23.
  • the lower end 24 of the drain plate 22 facing the paint tray 9 is expediently angled inward so that paint dripping along the drain plate will certainly get into the paint tray 9.
  • Bypass bores 25 can also be provided in the regions 11. As a result, an undesirably high hydrodynamic pressure on the doctor blade 4 can be avoided during operation, which can deform the blade knife 4 in particular in the case of a knife positioned positively on the anilox roller 10 and thus leads to an uneven adjustment to the anilox roller 10.
  • the surface of the anilox roller 10 takes the ink within the chamber doctor blade 1 in the circumferential direction of the anilox roller 10.
  • the color which does not enter the wells of the anilox roller 10 is carried along in the direction of the arrows b to d.
  • the speed is directly adjacent to the anilox roller 10, cf. Arrow b, largest.
  • the speed drops inwards, cf. Arrows c and d, ab.
  • the ink flow parallel to the axis of the anilox roller 10 is reduced. Even at medium speeds, this means that no more ink emerges through the gap 13.
