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.
  • the object of the invention is now to achieve equally precise distances within a narrow tolerance range more easily than according to the methods described above.
  • a precisely fitting fastening of the working element on the bearing bush of the rotating roller has the advantage, in addition to the fact that fewer components are now required, and the enormous advantage, among other things, that with significantly less work - i.e. with much less adjustment work - a textile machine can be manufactured.
  • FIG. 1 shows a fiber-dissolving roller 1 - here a beater roller - with the needles, pins or sawtooth set not being visible here.
  • the roller 1 is mounted with its shafts 2 in bearing bushes 4.
  • the right part I of the shaft 2 is shown in section, since it is further connected to a drive, not shown.
  • the axis of the roller 1 is designated 3.
  • a roller bearing 5 that can be a roller bearing or a needle bearing is shown purely schematically in the bushing 4.
  • On the sockets 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 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 likewise prismatic, at least in the region 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.
  • 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 it is not absolutely necessary for the surfaces of the attachment 6 to be at least partially prismatic, but it could also be Recesses can 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. However, 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.
