Definitions

  • the invention relates to a chamber doctor blade for use in an inking unit of a printing press, with an ink chamber which can be fastened to a support and can be connected to an ink supply, and two doctor elements which delimit the ink chamber at the top and bottom and can be adjusted to an anilox roller, and two side walls which delimit the ink chamber.
  • the invention has for its object to provide a chamber doctor blade which is simple to produce and exchangeable.
  • the chambered doctor blade according to the invention can be replaced as a whole when worn. As a result of very simple fasteners, handling is easy when changing. Another advantage is that there are no problems with the lateral sealing between the front area of the doctor elements and the side wall.
  • the chambered doctor blade according to FIGS. 1 and 2 has an ink chamber, generally designated 1, which comprises a rear wall 2, two side walls 3 and two doctor elements 4, 5. These parts delimit an interior space 6 which is open towards an anilox roller 7.
  • the ink chamber 1 is produced as a one-piece molded part. This can be done, for example, by casting, milling or non-cutting deformation.
  • the ink chamber 1 is suitably made of metal. However, it is also possible to manufacture them from a hard, wear-resistant plastic.
  • the chambered doctor blade also has a carrier 8, which is fastened to the printing press and can be adjusted with respect to the anilox roller 7, with one or more ink supply lines 9 and one or more ink return lines 10.
  • a hollow plug pin 11 is firmly inserted into the carrier 8, the front end of which projects beyond the carrier 8.
  • a hollow plug pin 12 is inserted into the extension of the color return line 10, which also protrudes beyond the carrier 8.
  • the carrier 8 is fastened in a manner known per se, not shown, between the side walls of the printing press in such a way that the two doctor elements 4, 5 can be set against the anilox roller 7 or can be set off from it.
  • the ink chamber 1 has 2 bores 13 in its rear wall, the position and size of which is dimensioned such that the ink chamber 1 can be pushed onto the pins 11, 12 by means of the bores 13 and is then held in a frictional manner on the carrier 8.
  • plug pins 11 which are connected to paint feed lines and are arranged in the central region of the paint chamber, while the plug pins 12 are advantageously arranged in the vicinity of the side walls 3 for the color return. If no forced passage of the color through the interior 6 is provided, the pins 12 can be omitted or can be designed as full pins. There is also the option of using pins instead of round corners.
