Definitions

  • the invention relates to a guide blade for a comminuting device, in particular a cutting device (eg for a knife ring chipper for cutting wood or the like) or for a stick mill, with at least one base plate and at least one interchangeable blow bar, which with a variable projection in one transverse to the beater bar longitudinal direction extending feed direction is fixed to the base plate beyond the base plate, wherein the beater bar is secured by a terminal strip to the base plate by the terminal block is clamped with one or more fasteners with the interposition of the blow bar against the base plate.
  • a cutting device eg for a knife ring chipper for cutting wood or the like
  • a stick mill with at least one base plate and at least one interchangeable blow bar, which with a variable projection in one transverse to the beater bar longitudinal direction extending feed direction is fixed to the base plate beyond the base plate, wherein the beater bar is secured by a terminal strip to the base plate by the terminal block is clamped with one or more fasteners with the interposition
  • Such a vane is z. B. for cutting devices, in particular used in Messerringzerspanern, where the raw wood in particular as bulk material, eg. B. is supplied in the form of wood chips.
  • a Messerringzerspaner usually has an (outer) rotating blade ring and a likewise rotatably driven within the blade ring racket wheel, which is also referred to as a rotor.
  • the invention also relates to machines in which the knife ring does not rotate. While the knives are fixed to the (outer) knife ring, guide vanes of the type described above are attached to the (inner) racket wheel, which spin the wood to be cut outwards on the knife ring.
  • the vanes or their base plates are equipped with blow bars, which are replaceable as wear parts.
  • the quality of the chips produced is largely dependent on a constant gap size between knives on the one hand and blow bars on the other hand. It is therefore not only necessary for a Messerringzerspaner nachzuschleifen the blades of the knife ring regularly and re-adjust, but also the blow bars of the racquet wheel must be regularly reworked and / or reset. It is particularly important that the supernatant of the blow bar can be easily and accurately adjusted beyond the base plate in a direction transverse to the blow bar longitudinal direction of feed.
  • both the mounting plate and the blow bar are provided with a profiling, which may be formed, for example, sawtooth. As soon as the usual amount of wear has been achieved, the fastening bolts can be loosened first, the blow bar removed and reground on a grinding machine.
  • blow bar can be inserted again in a position higher by a profile step position between the mounting plate and the guide vane, so that the racket wheel is ready for a new operating cycle after appropriate fixation.
  • a disadvantage of this solution is that the supernatant is adjustable only in relatively coarse steps, so that it lacks the possibility of a fine adjustment.
  • the groove is covered by a protective plate which is fastened by means of second clamping screws to the guide vane under the prestress of compression springs and which in this way fixes the impact plate in the axial direction by means of frictional engagement.
  • a protective plate which is fastened by means of second clamping screws to the guide vane under the prestress of compression springs and which in this way fixes the impact plate in the axial direction by means of frictional engagement.
  • In the form-fitting holder may be adjusting screws which are supported in operation with their end faces on the outer side wall of the groove provided in the guide vane and effect in this way the positive locking holder.
  • the invention not only relates to blades for knife ring chippers, but also to vanes for rackets in which the racket wheel is also provided with vanes, also referred to as strike plates. Interchangeable blow bars are also attached to these vanes or impact plates.
  • the racquet is usually from an annular grinding track, z. B. Prallmahlbahn concentrically surrounded with radial Mahlspaltabstand. Such a racket mill is generally used for fine comminution of (pre-shredded) substances. These may be substances of different materials, such. As wood or other renewable resources, but also from plastics or other materials.
  • Such racquets are for example from the DE 26 20 797 C2 , of the DE 33 17 144 C1 and the DE 41 01 352 C1 known.
  • the invention has for its object to provide a guide blade for a crushing device, in particular for a Messerringzerspaner or a racquet mill or for a racquet of such Messerringzerspaners or a club mill, which allows for a simple and stable structure optimum adjustment of the supernatant of the blow bar.
  • the invention teaches in a generic guide blade for a crushing device, in particular for a Messerringzerspaner for the cutting of wood or for a racquet mill that the clamping bar is displaceable by means of at least one adjusting element along the feed direction to change the supernatant of the blow bar wherein the terminal block is so positively connected to the blow bar that the blow bar is moved in the course of displacement of the terminal block with the terminal strip along the feed direction.
  • the adjusting element is preferably designed as a rotatable Exzenterstellelement.
  • the invention is initially based on the recognition that the adjustment of the supernatant by means of a suitable control element, for. B. Exzenterstellieris is expedient to realize a continuous adjustment.
  • This actuator, z. B. eccentric actuator engages within the scope of the invention, however, not directly on the blow bar itself, but on a separate terminal block, wherein the blow bar itself is clamped between terminal block and base plate. This can be dispensed with holes, slots or the like in the field of blow bar, so that in particular notch effects are avoided by drilling in the blow bar. Also, threads or the like need not be introduced into the blow bar, since the fixation is done using the still existing terminal block. Nevertheless, on the actuator, z. B.
  • Exzenterstellelement a stepless adjustment of the supernatant, said eccentric now no longer engages in the blow bar itself, but in the terminal block.
  • the terminal block is not fixed as in the known solutions in the prior art always in the same position on the base plate or the vane, but that the terminal block in the course of adjustment via the actuator or Exzenterstellelement itself is moved along the feed direction.
  • Positive-locking connection the terminal block with the blow bar means in this context a positive connection at least in the feed direction or along the feed direction.
  • Such a positive connection between the terminal block on the one hand and the blow bar on the other hand (along the feed direction) can be realized for example by the fact that the terminal strip on the blow bar facing back has at least one projection or a nose-like projection, which with respect to the feed direction positively in at least a corresponding recess (eg groove) in which the terminal strip facing front of the beater strip engages.
  • the blow bar on its front side have at least one projection
  • the terminal block has a corresponding recess on its back.
  • the recess and / or the projection may extend over the entire length of the beater bar or over substantially the entire length of the beater bar.
  • the length or longitudinal direction of the blow bar extends across the width of the racquet wheel and thus parallel to the axis of the racquet wheel.
  • the projections and depressions may be matched in their dimensions to one another that the projection can penetrate different depths into the recess. This can be useful if the terminal strip is moved slightly transverse to the feed direction in the course of adjustment. Because the eccentric is optionally not only rotated in the course of rotation, but also moved transversely to the feed direction and consequently along the axis of the bolt.
  • the terminal block on its back and the blow bar on their front each have at least one recess
  • at least a separate form-locking connection element is arranged, which relative to the feed direction both in the recess of the blow bar and engages positively in the recess of the terminal block.
  • This embodiment has the advantage that neither the blow bar nor the terminal strip must have a protruding over the back or front projection, but that only depressions are provided. This facilitates the production, since overall work is done with less material removal. Because it is not necessary to ablate almost the entire back of the terminal strip to produce a projection. In this case, however, then a separate positive locking element is required, which produces the positive connection (relative to the feed direction) between the terminal block and blow bar.
  • the eccentric actuating element preferably has an end-side eccentric, which (for example in one piece) to a first end of a bolt, for. B. a cylindrical or pin-like bolt is connected.
  • the eccentric which can also be referred to as eccentric head, then engages in a rear recess of the terminal block, so that in the course of the rotation of the eccentric, z. B. by rotation of the bolt, the terminal strip is moved along the feed direction.
  • the z. B. cylindrical or pin-like bolts, at the first end of the eccentric itself is connected, preferably passes through an opening in the base plate.
  • the blow bar itself is completely fixed separately, ie there are no openings for the Exzenterstellelement in the blow bar itself required.
  • the eccentric adjusting element at the second end of the bolt which projects from the rear side of the opening of the base plate, has an actuating connection to which a tool can be connected.
  • This actuating connection can be used, for example, as a polygonal connection, for. B. square connection be formed.
  • the eccentric can z. B. with a locking means, preferably a nut or lock nut, z. B. a self-locking nut, be locked. In this case, however, this lock is usually only the locking of the adjustment itself.
  • a locking means preferably a nut or lock nut, z. B. a self-locking nut, be locked. In this case, however, this lock is usually only the locking of the adjustment itself.
  • separate fasteners, z As fastening screws provided, however, also penetrate the base plate on the one hand and the terminal block on the other hand, without the need for drilling holes in the blow bar are required. It can z. B. two Exzenterstellmaschine per terminal block and z. B. two or three (or more) fixing screws per terminal block may be provided.
  • the bolt, at one end of the eccentric is connected, at least partially formed as a steep taper.
  • the opening in the base plate is then adapted in shape to this steep cone. It is advantageous in this embodiment, that in the course of adjusting the eccentric no self-locking occurs, so that the Exzenterstellelement is always easily solvable.
