Definitions

  • the invention relates to a device for fastening working elements, in particular a fixed carding element, with respect to a rotating, fiber-dissolving roller (CH-A-358 722).
  • the object of the invention is now to achieve equally precise distances within a narrow tolerance range more easily than according to the devices described above.
  • FIG. 1 shows a fiber-dissolving roller 1 - here an anvil roller - with the needles, pins or Sawtooth set is not visible here.
  • the roller 1 is mounted with its shafts 2 in bearing bushes 4. The right part of the shaft 2 is shown cut off, since it is further connected to a drive, not shown.
  • the axis of the roller 1 is designated 3.
  • a roller bearing 5, which can be a roller bearing or a needle bearing, is shown purely schematically in the bushing 4.
  • On the sleeves 4, an attachment 6 is visible on which a working element 7, here a fixed carding element, is attached.
  • the fixed carding element 7 consists of a carrier 8 and one or more combing inserts 9.
  • the carrier 8 is screwed onto the attachment 6 with screws (not shown).
  • the attachment 6 is prismatic in the region of the carding element 7, that is to say the connecting surfaces with the carrier 8 are in line with the surfaces of an n-square prism.
  • the carrier 8 is made of a drawn aluminum profile and has cavities 10 so that the stability is ensured and at the same time the heat generated during operation can be dissipated sufficiently.
  • On the left side of the carrier 8 there is a knockout knife 11 which is fastened to the carrier 8 with two Allen screws 12. Slits are not visible in the discharge knife 11, with which the exact position of the knife tip with respect to the saw tooth set of the roller 1 can be adjusted. As can be seen in FIG.
  • the carrier 8 is also prismatic, at least in the area of the attachment 6, as a result of which the carrier 8 is automatically positioned precisely with respect to the attachment 6.
  • the attachment 6 is in one piece with the bearing bush 4, which is usually formed from cast iron.
  • the attachment 6 is a separate part that is screwed onto the bearing bush 4 is.
  • this solution has the disadvantage that a less precise spacing of the working elements with respect to the roller is possible because the screw connection brings with it further tolerances.
  • the accuracy required without adjustment can be achieved in the embodiment shown because the support of the combing inserts or combing elements 9 lies exactly in the same or in a plane parallel to it as the support of the carrier 8 on the bearing bushes 4.
  • the surfaces of the attachment 6 could be at least partially prismatic, but recesses could also be provided in the carrier 8. These recesses can be, for example, angular grooves, for which purpose congruent elements are provided on the attachment 6.
  • prismatic design is preferred because of the simplicity of the solution.
  • the attachment 6 could, however, also be provided on the carrier 8 and corresponding cuts on the bearing bush 4 in order to meet the aforementioned condition.
