Definitions

  • the present invention relates generally to a granulator mill with easy positioning and adjusting of fixed blades arranged on a seat of the granulator mill.
  • Granulators are used for example within the plastics industry for recycling or reuse of plastic waste.
  • a granulator comprises a granulator mill for grinding plastic waste into granules of approximately the same mutual size.
  • One type of granulator may comprise a so-called cutter housing into which the granulator mill is positioned.
  • the granulator mill may comprise a rotor, onto which periphery knives are arranged and the knives cooperate with the static parts of the cutter housing such as cutter house walls or fixed blades/knives arranged at a frame or a seat or the like, of the cutter housing.
  • the periphery knives of the rotor may be arranged as low knives only protruding a small distance from the rotor.
  • EP3689571A1 discloses a strand pelletizer for pelletizing a strand of material and which has at least one cutting edge (rotor blade/knife) and an opposite cutting edge (fixed blade/knife).
  • the opposite cutting edge is arranged on a main part which can be moved relative to a support part (seat).
  • the main part can be independently linearly moved relative to the support part and can pivot about at least one pivot axis.
  • the strand pelletizer allows a simple and precise adjustment of the opposite cutting edge but at least has a drawback concerning that the adjustment takes place from the back side of the pelletizer and not from cutter housing side.
  • the wastepaper shredding component comprises a knife roller capable of rotating about its axis, a flying knife mounted on the knife roller and comprising a first blade means, a knife holder and a bottom knife, mounted on the knife holder.
  • the bottom knife comprises a second blade means engaging with the first blade means to cut wastepaper.
  • the second blade means extends in a direction along the axis of the knife roller.
  • the first blade means is inclined with respect to the second blade means, such that when the knife roller rotates, the first blade means can progressively engage with the second blade means from a first end thereof.
  • a granulator mill with improved accessibility for adjusting and/or replacing fixed blades of the granulator mill.
  • the granulator mill comprises a cutter housing with a granule chamber which extends in a first direction, and the cutter housing comprises a seat.
  • the granulator mill further comprises a rotatable rotor, arranged inside the granule chamber and arranged to rotate around a rotor axis that extends in the first direction.
  • the rotor comprises at least one first blade arranged at a periphery of the rotor, wherein the cutter housing at least partly surrounds the granule chamber.
  • the cutter housing comprises at least one fixed second blade arranged on the seat of the cutter housing, wherein the at least one second blade is arranged for cooperation with the at least one first blade of the rotor, for granulating waste material to granules.
  • the at least one second blade extends in the first direction and also in a second direction, which is transverse the first direction and thus extends in direction towards the rotor.
  • Each second blade comprises a front side which faces the rotor and an opposite back which faces away from the rotor in the mounted state on the seat.
  • the one or more fixed second blades arranged on the seat of the cutter housing of the granulator mill is/are easily accessed from the granule chamber/the rotor side, for adjusting or replacing the fixed second blade/blades.
  • the fixed second blade comprises at least one stop at the back side of each second blade, and which stop is arranged to position the second blade in the second direction by preventing the second blade from moving away from the rotor, a quick pre-setting function of the position of the second blade is achieved.
  • the second blade further comprises the tensioning screw which is connected to the seat and to the second blade via the recess, a further fine-tuning of the position of the second blade in the second direction (towards or away from the rotor/the first blade of the rotor) is possible with access from the granule chamber/the rotor side (front side).
  • the tensioning screw prevents the fixed second blade from moving towards the rotor, wherein the fixed blade, when perfectly positioned relative the first blade of the rotor, is prevented from moving in the second direction (towards or away relative the rotor) by the stop and by tensioning the tensioning screw.
  • the tensioning screw is connected to the second blade (via the recess) and to the back wall of the seat, wherein the tensioning "locks" the second blade in the correct position. If the preset distance does not totally correspond to a perfect position of the fixed second blade relative the first blade arranged on the rotor, the stop and the tensioning screw may be adjusted until a perfect position is reached, and then the position of the second blade is secured by the stop and the tensioning screw in the same way as described above.
  • the stops are preset and already attached to the back wall of the seat and the tensioning screw is normally attached to the back side of the second blade, wherein it is easy to fit the second blade on the seat by threading the T-shaped recesses over the tensioning screws, wherein the stop is very close to (or abuts) the back wall of the seat (or another stop part, see below), and lower the second blade such that it abuts the seat.
  • the second blade is adjusted on the seat to a perfect position relative the first blade of the rotor, and then is locked in this position at least by tensioning the tensioning screw. This provides a quicker setting and locking of the second blade compared to prior art solutions.
  • the tensioning screw comprises a neck portion arranged between the second end and the grip arrangement, which neck portion is dimensionally coordinated with the first part of the recess such that the neck portion fits into the first part of the recess of the second blade.
  • the at least one stop comprises a first pre-setting screw and a second pre-setting screw, wherein the first pre-setting screw is attached to the back side of the second blade in an adjustable manner such as a distance in the second direction, from the back side of the second blade to a distal end of the first pre-setting screw, is adjustable.
  • the second pre-setting screw is attached to a back wall of the seat of the cutter housing in an adjustable manner such as a distance in the second direction, from the back wall of the seat to a distal end of the second pre-setting screw is adjustable, wherein the position of the second pre-setting screw of the seat aligns with the position of the first pre-setting screw of the second blade.
  • the first pre-setting screw is in threaded connection with a threaded hole arranged at the back side of the second blade and the second pre-setting screw preferably is in threaded connection with a threaded through hole arranged at the back wall of the seat.
  • the through hole arranged at the back wall of the seat may of course be a hole without threads and in that case, the second pre-setting screw may be adjusted and locked in position relative the seat by means of a respective nut arranged on both sides of the back wall of the seat and in threaded connection with threads of the second pre-setting screw.
  • the first pre-setting screw and the second pre-setting screw aligns with each other and when mounting the second blade to the seat, the first pre-setting screw abuts the second pre-setting screw which already is mounted at the seat (preferably at the back wall of the seat by threaded connection and a stop nut).
