Definitions

  • the subject invention relates to a device for releasably securing a holder for a scraper blade, which is assigned in a plant for paper production of a support and guide roller, on a support, wherein the holder on the support at least approximately in the direction of the support or Further, the holder is formed by holding fingers extending transversely to the pivot axis, which are each formed with a first bearing part, which interacts with a second bearing part located on the carrier and at least between the holder and the carrier an actuator is located, through which the retaining fingers are independently pivotable.
  • the carrier and guide rollers each associated with a scraper blade, which is brought to the relevant support and guide roller to the plant, which are scraped off by the roller on this pollution.
  • the holder for the doctor blade is formed with a device for adjusting the angular position of the doctor blade relative to the respective roller. Further, since the holder for the doctor blade must often be replaced in order to clean this and the doctor blade, there is also the need to attach the holder for the doctor blade on the support for the holder in such a way that it can be solved in the simplest possible way ,
  • the holder for the scraper blade and the carrier for the holder are formed with tabs projecting towards each other, which are formed with associated bores into which a bearing pin extending over the width of the screen belt is inserted.
  • the bearing pin is pulled out laterally.
  • the holder for the doctor blade from the carrier can be removed so transversely to the longitudinal direction of the bearing pin from the carrier.
  • there is often the difficulty that due to the structural design of the system for a movement of the holder transversely to the carrier required space is not available.
  • the subject invention is therefore the object of the attachment of the holder for the doctor blade on the support for the holder in such a way that the holder for the doctor blade against the carrier in the longitudinal direction of the bearing pin is displaceable, without being moved by the carrier transversely to the sliding direction so it needs to be lifted from this.
  • This object is achieved in that one of the two bearing parts is formed by a bearing shell, which is formed with a extending in the direction of the pivot axis recess, in particular with a slot, and the other bearing part is formed by a bearing pin, of a Recess of the bearing shell passing through web or the like. is supported, whereby the holder relative to the carrier in the direction of the pivot axis over the entire length of the doctor blade is displaceable.
  • each retaining finger is formed with a separate bearing part, whereas the bearing part located on the carrier extends integrally over the entire length of the doctor blade or is formed by individual mutually spaced apart portions of the bearing part.
  • each retaining finger is associated with a bearing pin, which by means of a web or the like. is attached to the retaining finger and is provided on the carrier over the length of the doctor blade extending strip-like bearing shell or more sections of the strip-like bearing shell are provided, wherein the at least one bearing shell on its holding fingers associated side with recesses, in particular with slots formed.
  • a covering plate extending over all holding fingers is furthermore provided, which is fastened to the holding fingers and which rests against the edge of the scraper blade assigned to the holder.
  • the retaining fingers may be formed on their end associated with the doctor blade with a profiling which serves to fasten the doctor blade.
  • the retaining fingers are formed at their end associated with the scraper blade each with a recess into which a protruding from the doctor blade strip can be used.
  • the retaining fingers are designed as two-armed lever, which are mounted in its central region on the carrier and the carrier for the retaining fingers is formed with a holding finger cross-flexible cover.
  • FIG. 1 a support and guide roller 1 is shown, which is located in a plant for paper production below the screen belt, the felt belt or the paper tape.
  • the roller 1 is associated with a doctor blade 2, which can be brought to the surface of the roller 1 for conditioning, being directed opposite to the direction of rotation of the roller 1.
  • the doctor blade 2 are on the surface of the roller 1 located contaminants, which are caused by the dewatering of the screen belt located Textilbreies or by the drying of the paper tape removed.
  • the doctor blade 2 is attached to a holder 3, which is formed by a plurality of juxtaposed holding fingers 31 and a covering plate 32 located above it.
  • the scraper blade 2 is formed on its edge facing the holder 3 with a bar 21 which protrudes into recesses 33 provided at the ends of the holding fingers 31. Furthermore, by means of the cover plate 32, which is screwed to the retaining fingers 31, all holding fingers 31 are connected together to form a single unit.
  • the holder 3 for the doctor blade 2 is pivotable by means of a bearing 4 on a support 5 for the holder 3 with respect to this.
  • a bearing 4 on a support 5 for the holder 3 with respect to this.
  • a flexible covering element 51 is provided on the ends of the holder 3 or of the carrier 5 facing away from the doctor blade 2.
  • the carrier 5 is located on a pivot arm 7, which is fixed to a shaft 8, which extends in the axial direction of the roller 1 and which is adjustable by means of a turnbuckle 9 in a pivot position and lockable in this.
  • FIG.2 are the doctor blade 2, the holder 3 for the doctor blade 2 with one of the retaining fingers 31 and the cover plate 32, the bearing 4 for the holder 2 on the carrier 5, the adjusting elements 6 and the cover 51 can be seen.
  • each retaining finger 31 is formed with a bearing pin 41.
  • the bearing pins 41 are mounted in mounted on the carrier 5 bearings 42.
  • each bearing pin 41 can be assigned a separate bearing shell 42 or a plurality of bearing pins 41 can be assigned a common bearing shell 42.
  • the recesses 33 located in the retaining fingers 31 can be seen.
  • the bearing pins 41 located on the retaining fingers 31 are fastened to the retaining fingers 31 in each case by means of a web 41a. Furthermore, the bearing pins 41 are attached to the support 5 mounted bearing shells 42, which are formed on its holding finger 31 side facing a slot 42a. The inside width of the slot 42a is slightly larger than the thickness of the webs 41 a. Due to this design of the bearing 4, the retaining fingers 31 relative to the carrier 5 in the axial direction of the bearing pin 41 are freely displaceable.
  • the holder 3 with the retaining fingers 31 and the cover plate 32 at the same time be solved with the doctor blade 2 from the carrier 5, that it is moved axially relative to this, without being removed from this transversely to the axis of the bearing pin 41 so lifted from this , As a result, it is met the requirement to be able to remove the holder 3 for the doctor blade 2 from the carrier 5 for the holder 3 even if there is no space available to lift the holder 3 from the carrier 5.
