Definitions

  • the subject invention relates to a device for cleaning a roller in a plant for paper production with a surface of the roller associated scraper blade, which is pivotally mounted relative to the roller by means of two aligned parallel to the axis of the roller bearing journal, wherein at least one of the two journals an adjusting lever is fastened, by which the doctor blade is pivotable.
  • Known devices of this kind are used to remove impurities, particularly in the form of fibers, located on the surfaces of rolls in papermaking plants, in order to ensure a function of the rolls corresponding to the requirements.
  • the scraper blade is at one extending over the length of the roller Scraper attached.
  • the scraper is at its two ends with trunnions formed, by means of which it is rotatable in bearings. Furthermore, they are Bearing transversely to the axis of rotation of the roller adjustable.
  • the subject invention thus has the object, in such Establish the connection of the actuating lever with the associated bearing pin Although form-fitting form, whereby an undesirable adjustment excluded However, it should nevertheless be possible to have the Rotary position of the journal relative to the lever to the technical requirements to adjust accordingly.
  • a roll 1 is shown in a plant for paper production, which a doctor blade 2 is assigned.
  • the scraper blade 2 is located on a Scraper bar 3, which is parallel to the axis of the roller 1 over the entire Length extends.
  • At the bearing pin 4 are Adjusting lever 6 attached, which about actuators 7 about the axis of the bearing pin. 4 are pivotable, whereby thereby a rotation of the bearing pin 4 and a Pivoting of the scraper bar 3 and the scraper blade 2 with respect to the surface the roller 1 takes place.
  • the bearings 5 are adjustable transversely to the roller 1, This is also the angle of attack of the doctor blade 2 relative to the roller. 1 adjustable.
  • the bearing 5 is adjustable in the direction of the double arrow C relative to the roller 1.
  • the adjusting device 7 is formed by a set screw or by an actuating cylinder. By actuating the adjusting device 7, the adjusting lever 6 is pivoted or the bearing pin 4 is rotated. As a result, the doctor blade 3 is pivoted with the doctor blade 2 relative to the roller 1. By adjusting the bearing 5, the doctor blade 2 can be brought to the roller 1 to the plant. Reference is also made to the illustration of Figure 3, in which different angles of the doctor blade 2 are indicated.
  • the adjusting lever 6 is formed with a clamping sleeve 8, which consists of two parts 81 and 82 which are connected to each other by means of two screws 84.
  • the clamping sleeve 8 serves to positively connect the adjusting lever 6 with the associated bearing pin 4, thereby ensuring a rigid connection of the actuating lever 6 with the shear bar 3.
  • This connection consists in that the part 82 is formed on its inner side with a toothing 83 formed parallel to the axis of rotation of the bearing journal 4, which toothing 43 is assigned a counter toothing 43 on the bearing journal 4. In this case, the teeth 43 opposite the teeth 83 extends approximately twice the angle.
  • the toothing 43 of the pin 4 is characterized manufactured, that the pin 4 is formed with a flattening 40, which a support member 42 is associated, which is formed with the toothing 43.
  • These Training is particularly advantageous insofar as a flattening on the journal 4 can be produced in a very simple manner. This flattening only needs the formed in cross section as a circular section support member 42 applied to which is formed on its outer surface with the teeth 43.
  • the doctor blade 3 is pivoted.
  • the two sleeve parts 81 and 82 from each other dissolved, whereby the toothing 83 can be released from the teeth 43.
  • the bearing pin 4 are rotated, whereby the angular position of the doctor blade 2 is changed relative to the roller 1.
  • the two sleeve parts 81 and 82 screwed together by means of screws 84, whereby the Serrations 83 and 43 are locked together and a positive connection is achieved.
