Definitions

  • the invention relates to a textile machine with so-called flight - in a particle or fiber-containing space - producing processing elements connected to at least one drive, in particular rollers in a room with a drafting device for fiber slivers.
  • the drive for the rollers or the like should Machining elements are arranged in a drive housing and the interior thereof is provided with excess pressure.
  • This interior should be provided with overpressure, advantageously air and dust-free air introduced into the overpressure.
  • a controlled air flow is thus generated in the area of the drafting system; clean air is supplied in the draft zone of the drafting system and the exhaust air loaded with fiber fly, dust and other contaminants the drafting room, which is limited in size.
  • the supply of contaminated ambient air at the sliver inlet is reduced to a minimum.
  • the motors - preferably with the drive trains connecting them to the rollers - are protected from flying fibers in the air space located outside the drive housing by the excess pressure.
  • the drive housing itself is not a completely sealed capsule; In the areas of the required housing openings, air cushions slowly migrate outwards thanks to the excess pressure inside the drive housing, which enables the interior to be sealed against those stray fibers and particles.
  • the rollers of the drafting system or the like have proven to be particularly favorable. to be provided in a vacuum flow. That's about it At the other end, the drafting system housing, which is open at the inlet, is connected at its other end to a suction device, so that air flows in the conveying direction and thus increases the pressure drop between the drive interior on the one hand and the roller area on the other hand.
  • a drive unit 10 of a textile machine for processing fiber tapes which are only indicated for the sake of clarity in the drawing, and which are fed from cans to an infeed table with a downstream drafting device, has a roller group 14 comprising rollers 15 and pressure rollers 16 for the pre-drawing of the fiber tapes in the conveying direction x follows a roller group 18 for the main draft with the main roller 19, 19 a and pressure rollers 20; two guide rollers 22 are connected to the main drafting group 18.
  • the shafts 13 of the rollers 15 and a shaft 17 of a main roller 19 are connected by a drive train 24 to a drive 26, the shaft 17 a of the other main roller 19 a and a shaft 21 of the guide rollers 22 are driven by further drive trains 28, 29 from one Motor 30 driven.
  • a suction device 36 for the Air flowing in in the direction of arrow a is added.
  • the suction 36 generates a negative pressure in the housing space 38.
  • the motor or interior 40 of the drive housing 34 is connected to a conditioning device 44 by a line 42. This ensures that specifically conditioned air reaches the interior 40 for permanent maintenance of the excess pressure and that used air escapes through cracks and gaps or is selectively discharged.
  • a micro-dust filter 46 is inserted into the line in front of the conditioning device 44 to keep the air or the separation of the micro-dust that occurs, which filter can be designed as an exchangeable or knocking filter or in another design.
  • Arrow z indicates that, for example, pure exhaust air from the area of machine electronics 48 is used to feed the drive housing 34.
  • a sliver mat 50 that is to say a plurality of slivers aligned next to one another and parallel to one another, is guided in the drafting chamber 52 open at the strip inlet 51 between rollers 15, 15 a and planetary rollers 54 to a draw-off roller group 56
  • Suction channel 58 is provided over the entire fleece width b, as a result of which the flight arising in the drafting room 52 can be transported away in the shortest possible way.
  • An engine compartment 40 accommodating the drives 25 is sealed off from the drafting system and provided with clean air under excess pressure. This prevents the ingress of particles from the drafting chamber 52 which is driven with negative pressure; there is also an air flow to the drafting chamber 52.
  • the arrows y in FIG. 4 illustrate the entry of ambient air into the drafting device space 52.
