Definitions

  • Fiber cutting devices are already known in which fibers are cut with rotationally drivable cutting units (cutting unit systems or roll systems).
  • the fibers are supplied to the rotating cutting units with compressed air, wherein the fibers are conveyed during cutting work as a roll system by a pressure roller and cut and / or broken between cutting of cutting units and counter-pressure units.
  • the invention is based on a fiber cutting device with at least one cutting unit and at least one counterpressure unit, wherein at least one of the units is mounted on the other unit for cutting at least one fiber, in particular fiber bundles.
  • the counter-pressure unit and / or particularly advantageously the cutting unit is displaceably mounted in at least one direction and driven in at least one operating mode.
  • rolling on the other unit is understood to mean that at least one unit performs a rotational movement in contact with the other unit in one cutting operation, rolls on the other unit, and travels a distance on the other unit as a result of the rotational movement.
  • a “cutting unit” is to be understood in particular as a unit which has at least one cutting element which is intended to cut and / or break the fiber.
  • a cutting operation can advantageously be influenced, in particular if the counterpressure unit and / or preferably the cutting unit are at least essentially, i. with an angular deviation of less than 10 ° and preferably less than 5 °, is mounted reciprocatingly movable parallel to its axis of rotation and driven in at least one operating mode, whereby a so-called pulling cut can be achieved.
  • Only one of the units can be rotatably mounted, while the other unit provides a movably mounted or even stationary rolling surface.
  • both the cutting unit and the counter-pressure unit are rotatably mounted, it is particularly advantageous to achieve a space-saving device which can be advantageously designed for a continuous process.
  • roller-shaped should be understood to mean, in particular, a body shape which along an axis of symmetry, which preferably coincides with a rotation axis, has an extension at least twice as large as perpendicular to this axis of symmetry, in particular like a diameter of the cutting unit and / or the counterpressure unit.
  • both the cutting unit and the counter-pressure unit is formed by a roller and at least one fiber, preferably a plurality of fibers and more preferably a plurality of fiber strands are cut between the at least two rollers rolling on each other.
  • roller-shaped cutting unit has at least one helical cutting edge
  • the cutting process can also be improved.
  • "thread-shaped” is to be understood in particular as meaning that the cutting edge has, in addition to an alignment component, an alignment component in the circumferential direction parallel to a longitudinal or rotational axis of the cutting unit.
  • the fiber cutting device at least one Printing unit, which is intended to press at least one fiber against the counter-pressure unit, whereby a particularly advantageous fiber supply can be achieved, in particular when the printing unit is cylindrical.
  • the counter-pressure unit has a coating, preferably a plastic coating.
  • a coating is to be understood as meaning, in particular, a material layer which differs from a base material located below the coating.
  • the counter-pressure unit can be particularly advantageous adapted to their function.
  • This surface of the counter-pressure unit, in particular the plastic coating preferably has a Shore A hardness of between 50 and 95 Shore.
  • FIG. 1 shows a schematically illustrated fiber cutting device with a separating unit 10 and a counter-pressure unit 12, wherein for the continuous cutting of fiber strands 14, the units 10, 12 are mounted on each other umicalzbar.
  • the cutting unit 10 and the counter-pressure unit 12 are formed roller-shaped and are rotatably mounted about their mutually parallel axes of rotation 36, 38.
  • the roller-shaped cutting unit 10 is rotatably drivable by means of a motor 26 and has a plurality of successively arranged, helical cutting edges 20 in the circumferential direction.
  • the blades 20 are formed by band steel blades which are secured in grooves of the cutting unit 10.
  • the cutting edges 20 extend over an entire width of the cutting unit 10.
  • the cutting unit 10 is slidably mounted in directions 16, 18 parallel to its axis of rotation 36 and is moved during a cutting operation, i. in particular during a rotational movement of the cutting unit 10 and the counter-pressure unit 12, reciprocated by means of an actuator 30 on a base body 32, so that relative movements between the counter-pressure unit 12 and the cutting unit 10 in the directions 16, 18 arise.
  • the counterpressure unit 12 is pressed against the cutting unit 10 by means of a contact force in the radial direction of the cutting unit 10.
  • the contact pressure is generated by a pressing unit 28, which acts on the counter-pressure unit 12 and presses the same against the cutting unit 10.
  • the counterpressure unit 12 has a plastic coating 40 which in particular has a greater resistance to cutting than a base material 44 of the counterpressure unit 12.
  • the fiber cutting device has in the direction of a longitudinal axis of the cutting unit 10 or in the direction of the axis of rotation 36 of the cutting unit 10 successively arranged fiber feed units 34.
  • the fiber supply units 34 have tubular supply means within which the fiber strands 14 are guided.
  • the tubular supply means are bent, whereby a space-saving feed is achieved.
  • the fiber cutting device has a roller-shaped, rotatably mounted pressure unit 22, which is provided to press the fiber strands 14 against the counter-pressure unit 12.
  • a storage, via which the printing unit 22 is rotatably mounted, is not shown in detail.
  • the printing unit 22 has an axis of rotation 42 running parallel to the axis of rotation 38 of the counterpressure unit 12 and is pressed against the counterpressure unit 12 by means of a contact force in the radial direction of the counterpressure unit 12.
  • the contact pressure is generated by pressure cylinders 24, which act on the pressure unit 22 and press the same against the counter-pressure unit 12.
  • the fiber strands 14 are fed between the counter-pressure unit 12 and the printing unit 22 and are then passed between the counter-pressure unit 12 and the cutting unit 10, between which the fiber strands 14 are cut.
