Definitions

  • the invention relates to a device for crimping synthetic yarn sheets, bundles or tapes with a pair of press rolls and a stuffer box downstream thereof, which consist of two plates aligned parallel to the axes of the rolls, one of which may be at least partially against the other can be pivoted to reduce the chamber space, and there are two side walls delimiting the chamber space up to the press roll nip, in each of which, at the level of the press roll nip, one of the edge areas of the roll end faces assigned by an adjusting unit z. B. is applied with a pressure against the roller end faces, generally cylindrical cut thrust washer.
  • a device of this type is e.g. B. known from DE 21 17 393 A1.
  • the edge area between the press roll nip of the feed roller pair and the thrust washers intended for wear is one of the most difficult to control of the entire stuffer box crimping device.
  • the construction must ensure that the fibers conveyed into the stuffer box by the pair of feed rollers at high pressure are not squeezed out of the side of the device.
  • the wear which must necessarily occur between the rotating roller end faces and the stationary pressure plate, should be reduced to a minimum, but in particular be uniform on the surface of the pressure plate.
  • the disc Depending on the pressure set against the back of the pressure disc, the disc must still be replaced frequently, for example after 4 - 6 hours of operation. The disc is then to be replaced by a new one and the used one in a z. B. To free the grinding shop from the operating marks. This exchange and sleep process is possible several times, but the disc is used up after about 10 renewing grinding processes and must then be thrown away with its rear drive bores and the threaded holes required for replacement on the peripheral surface of the pressure disc. Except from the fact that this is a high loss of material, the investment of the grinding device and the work necessary for renewal and the like must also be taken into account.
  • the invention has for its object to develop a thrust washer on which the effort of regrinding and thus the acquisition of the grinding machine with the necessary operation can be eliminated.
  • the thrust washer is composed of a carrier disk and a wear element fastened to it.
  • the carrier disc can be made of any material and used over and over again.
  • the precision work on the carrier disc with the individual bores and threads is only necessary once.
  • the wear area of the thrust washer is determined by a separate wear element which can be replaced at any time and which has to be produced solely from the softer and more expensive non-ferrous metal.
  • the carrier disc can now be made of a porous material such.
  • B. are made of a sintered material which - as provided in DE 33 26 589 A1 - can be cooled from the back with a fluid.
  • a porous material for the thrust washer could not previously be used because the pores of the wear surface were repeatedly sealed with the grinding dust during the previously required grinding.
  • the device for crimping synthetic thread sheets consists essentially of the rollers 1 and 2 serving as the feed and press roller pair and the downstream stuffer box 3, which by the two axially aligned to the rollers 1, 2 plates 4, 5 - of which the plate 5 against the plate 4 is pivotally mounted to reduce the chamber space 3 - And is limited by the two to the press roll nip 8 extending side windows 6, 7.
  • the side windows 6, 7 are rigidly attached to the lower plate 4.
  • pressure disks 9, 10 are freely rotatably mounted at the level of the press nip and pressurized in the direction of the arrow.
  • the drive for rotating the thrust washers about their horizontal axis is not shown for simplicity. In general, this is done via bores in the back of the pressure disks 9, 10 with spikes of the drive engaging in the bores.
  • the thrust washers 9, 10 do not consist of a single body, but instead of the carrier disc 11 and the wear element 12.
  • the wear element 12 slips onto the wear side of the carrier disc in the form of a cover Non-ferrous metal used. It is stamped from such a sheet in a simple manner and then bent up with a collar 13 to form a cover.
  • This cover fits positively on the carrier disk 11 provided with a corresponding groove 14 on the circumference and should be connected in a rotationally fixed manner to the carrier disk 11 via this collar 13.
  • Other mounting options are possible.
  • the carrier plate material can be made particularly cheaply or else from sintered material that is porous and therefore better suited for cooling the pressure plate with a liquid.
