Definitions

  • the invention relates to a knife ring according to the preamble of patent claim 1 and to an apparatus for comminuting feed material with a knife ring enclosing a comminuting space with the features of patent claim 14.
  • Known crushing devices are known, for example, as Messerringzerspaner with an internal Schlagradsystem in which wood chips are crushed into fine chips and serve as a raw material for chipboard production.
  • Langholzzerspaner in which the fixed feed material is converted by a rotating and transverse knife ring into large-scale chips, which are used in the further for the production of OSB products.
  • the actual crushing work of such devices is done by the Zerspanmessern, which are assembled together with a knife-holding plate outside the crushing device within a gauge to a knife package.
  • the knife assemblies are held by knife carriers, which are arranged in a circle between two carrier rings about an axis of rotation and thus form the knife ring.
  • the knife carrier has an over the entire length of the knife carrier extending stop surface as a reference surface, which cooperates with the opposite side of the cutting blade of the preset blade package. This serving as a reference surface stop surface is also referred to as a zero position for the knife packages, since it is taken from the nominal dimension for the position of the cutting edge of the Zerspanmessers.
  • the top priority when assembling the knife packages is that all cutting edges of the cutting blades lie on a cutting circle.
  • the reference surface is formed by an adjusting and fixing screw, which can be screwed in or out of plane parallel to the knife package in the knife carrier.
  • the adjusting and fixing screw serves as a stop for a continuous counter-pressure bar, which is firmly bolted to the knife package.
  • EP 0 807 500 A2 a chipper for wood chips with a knife ring, which is essentially formed by a plurality of knife carriers with units of knives and clamping plates arranged thereon. These units are clamped by means of screws on the knife carrier, wherein in the region of the outer circumference of the knife ring between the knife carrier and the clamping plate a form-fitting generating molded body is arranged. The molded body can be inserted from the side into the gap between the knife carrier and clamping plate and has different cross sections.
  • the invention has the object of further developing generic knife rings to the effect that Zerspanmesser can be used with a larger than previously possible useful width.
  • the basic idea of the invention is to make the reference surface on the knife carrier, which cooperates with the knife package, substantially punctiform. Together with Zerspanmessern, which in the area of the reference surfaces each one of Having rear edge emanating recess, therefore, results in a constructive design of a knife carrier, wherein the reference surfaces come to rest within the recesses and thereby the rear edge of the Zerspanmesser can extend beyond the reference surface addition.
  • the reference surface can be formed by a fixed stop or even by a plane parallel to the knife package adjustable adjustment.
  • the operator of knife rings and comminution devices according to the invention has the advantage of using wider cutting blades than this was previously possible. These Zerspanmesser have a longer life due to their greater useful width, so that the economy of total crushing devices increases overall.
  • inventive design of a knife carrier allows the displacement of the reference surface towards the center of the knife carrier. This results in a squat design of the individual knife carrier, which opens the possibility to accommodate more knife carrier on a perimeter line than before. Such a modified blade ring is able to perform a higher crushing performance.
  • the reference surface consists of a stop on the knife carrier for the knife package.
  • Such an embodiment is characterized by the simplicity of construction, but acts only in the direction of the stop, i. H. A knife package must be held against the stop until it is screwed tight to the knife carrier.
  • a positive connection between the blade carrier and the blade package is generated with the reference surface, for example by forming a connector.
  • a preferred connector according to the invention has the tongue and groove principle.
  • the groove is arranged in the knife holder plate and the spring in the knife carrier. This allows a compact design of the knife carrier with a simple design. A longer relative to the spring groove facilitates threading the spring into the groove and allows minor position corrections in the groove direction in retrospect.
  • the invention allows adjustment of the reference surface and thus an adjustment of the zero position for the knife packages.
  • the reference surface cooperates with the adjusting device, which is arranged on the knife ring.
  • a simple, but very effective and reliable type of adjusting device consists of an adjusting screw, which can be screwed to the knife carrier with the interposition of spacer plates. It is possible that the head of the adjusting screw itself represents the reference surface for the knife package. Alternatively, it is possible with the adjusting screw, again with the interposition of shims, to secure a centering on the knife carrier, which cooperates with the knife-holding plate.
  • the arrangement of niches on the knife carrier is advantageous.
  • the adjusting device disappears in the cross section of the knife carrier.
  • the chip removal channel can be kept free of disturbing cross-sectional constrictions, which always represent a source of danger with regard to blockages.
  • inventive crushing devices are characterized by a higher reliability and reliability.
  • the support surface of the knife carrier on a pedestal on which rests the knife plate in the operating state is provided.
  • the arrangement of the reference surface or the adjusting device in the region of the base has the advantage that, in static terms, the base itself acts as a stabilizing element for the reference surface.
  • the knife ring is also marketed on the market as an independent part of a shredding device.
  • FIG. 1 an inventive Messerringzerspaner is shown in the form of a Langholzzerspaners.
  • a wood chip scraper with blade ring and internal Schlägerrad would be suitable, the knife ring can be both stationary and rotating.

While the rear wall of the housing 10 is closed and serves to support the drive shaft of the knife ring 11, the front side of the housing 10 has a circular opening, through which the crushing chamber 12 is freely accessible.
  • the crushing chamber 12 is bounded above by a circular arc segment 13, whose curved side extends at a small distance from the blade ring 11.
  • a stiffening base construction 14 delimits the comminution chamber 12 and, like the circular arc segment 13, is fixedly connected to the housing 10.
  • the left-hand boundary surface of the comminution chamber 12 in the plane of representation is formed by an axially projecting into the comminution chamber 12, in cross section convex counter-surface 15 which is stationary relative to the machine base 1 and thus does not follow the transverse movement of the machine base frame 3.
  • the opposite side of the crushing space 12 is finally formed by a portion of the inside of the knife ring 11 and at the same time represents the crushing path.
  • the feed material in the form of tree trunks 16 projects, like the counter-layer 15, axially into the crushing space 12 with the free part of its length.
