Definitions

  • the invention relates to a method and an apparatus for extruding or extruding a mixture of small plant parts, in particular small wooden parts with binders, in which the mixture is compressed by the ram of an extruder in a filling chamber and solidified in a curing channel.
  • the batch should be transferred in a felting state by means of an extended stroke of 400 to 800 mm and a feed speed of the extrusion die of 0.04 to 1.5 m / s, which should result in increased strength of the strand.
  • the parts of the batch lie with one of their large areas parallel to the lower boundary wall of the filling chamber. During the compression process, they try to fold parallel to the end face of the extrusion die. However, a larger volume of the filling space would be necessary for this transfer.
  • the closing slide which closes the filling chamber during the compression process, does not make it possible to increase the volume by moving parts of the batch into the filling chamber.
  • the volume of the press ram becomes smaller and smaller until the final compression is achieved. As a result, the parts of the batch can only partially change their original position and become entangled when they are compressed. This happens regardless of the feed rate of the ram.
  • the mixture of small plant parts does not behave like a liquid when compacted, which distributes the pressure evenly on all sides, but rather the pressure acting on the parallel boundary walls that delimit the filling space, as well as the compression, the weights and the specific weight of the strand part produced with the compression stroke of the extrusion stamp on the end face of the extrusion stamp is greatest and takes to the front end of the pressed strand part, which adjoins the strand part generated in the previous compression stroke.
  • the lower compressed start of the next strand part follows the higher compressed end of a strand part produced with each press stroke.
  • the invention has for its object to provide a method for extruding a mixture of small plant parts with binders, the product obtained being as homogeneous as possible over the entire length and thus withstanding a higher load and thus load-bearing components such as beams can be produced and only as much batch is compressed as is necessary to achieve the necessary strength.
  • the invention is based on the knowledge that the greater the difference in compression of the strand parts at their ends or over their length, the smaller the breaking strength (bending strength) of a strand, and that the greater the difference in compression, the longer the compression stroke and thus the strand section generated.
  • the angle of the wedge-shaped extension is determined by the profile of the strand, the length of the filling space and the size of the compression.
  • part of the pressing force of the extrusion die is transferred to the boundary walls during compression.
  • the part of the pressing force acting on the boundary walls is greatest at the end of the extrusion die and at the other end it is the least. Since the structure of the parts of the batch is largely preserved during compression, only a certain part of the parts of the batch want to avoid crosswise to the pressing direction. The material therefore does not flow through the smallest slits, as in metal extrusion, for example, when compacting.
  • the filling space is designed to widen in a wedge shape, the parts of the batch at the end of the hardening channel cannot escape outwards, but the parts of the batch at the end on the extrusion side can yield by the amount of the wedge-shaped expansion.
  • the invention shows that when the final compression of the extruded part generated with the press stroke, the force acting on the boundary surfaces of the filling space at any point, on a line, in the length of the extruded portion is equal or at least approximately is the same size.
  • the compression, the weights and the specific weight are equally large.
  • Another advantage of the invention lies in the surface properties of the strand produced. Since the same compression prevails over the length of the strand section and thus over the entire strand, there is also the same surface structure, the same degree of roughness, the same appearance and is essential for finishing the strand with veneers, useful wood or other load-bearing materials same proportion of profile load (DIN 4762).
  • Another advantage of the invention results from the uniform compression over the length of the strand section produced with each press stroke.
  • the needle extraction value is correspondingly uniform.
  • Products with comparable strength can be produced with low compaction force and the use of materials, or correspondingly higher-quality or dimensionally smaller products that can be nailed without problems, since there are no or only very slight fluctuations in the nail extraction value.
  • the final product produced e.g. As a result, pallets can be manufactured at higher quality or at lower cost. This also results in a lower weight.
  • the invention can be combined with closing slides, curing channels and filling and pressing rooms.
  • the mixture of small plant parts reaches a filling chamber 1 into a filling chamber 2, the inlet opening of which is closed by a closing slide 3 during the compression process.
  • the passage opening 4 of the closing slide 3 which can be moved back and forth by the lifting device 5, is above the inlet opening of the filling chamber 2 and allows the batch to fall through from the filling shaft 1 into the filling chamber 2.
  • the cross section of the filling chamber 2 widens with the angle 6 from the size 7 of the extrusion-side end 8 to the size 9 of the hardening channel end 10.
  • the parts of the batch located on the extrusion die side end 8 can, however, deviate transversely to the direction by the amount of the wedge-shaped extension, that is to say the dimensional difference between the size 7 of the extrusion die side end 8 and the size 9 of the hardening channel end 10.
  • the parts of the batch located between the ends 8 and 10 can, however, move transversely to the pressing direction according to their position in the filling space 2.
  • the part of the compression pressure acting transversely to the extrusion direction through the extrusion die 11 on the batch at any point, on a line lying in the pressing direction of the strand section produced with the compression stroke is the same or approximately the same size, since the parts of the In accordance with their position in the filling chamber 2, the compression pressure can partially evade.
