Definitions

  • the invention relates to a device for loading the filling space of a horizontal piston extruder with a mixture of small plant parts and binders for the production of hollow prismatic extruded profiles, in which the upwardly open side of a filling funnel facing the filling space penetrated by at least one mandrel through one and moveable closing slide can be covered.
  • Piston extrusion presses work in time. The one in the filling room . immersing piston compresses the mixture therein and presses it through a shaping recipient into a heated curing channel, where the binding of the binder takes place due to the action of heat as the strand progressively moves forward in cycles.
  • the filling space of such a piston extrusion press is usually in free fall from a loading funnel which is arranged above the filling space and whose outlet opening below is delimited by a closing slide.
  • a loading funnel which is arranged above the filling space and whose outlet opening below is delimited by a closing slide.
  • a passage opening in the closing slide there is a passage opening in the closing slide, the cross section of which corresponds approximately to the filling opening of the filling space. If the passage opening is congruent with the outlet opening of the loading funnel, the filling space can be filled with the mixture. This happens when the extrusion piston is retracted.
  • the problem is solved with the invention in / as yet unsolved problem, to produce hollow-prismatic extruded profiles in cross-section from a mixture of small plant parts and binding agents.
  • Such hollow prismatic cross sections require a corresponding cross section of a mandrel in the filling space.
  • An area of the filling space would then be present below the prismatic mandrel, which cannot be adequately filled due to the free fall of the mixture, which is often called non-flowable.
  • a vertical cold extrusion press would not have this problem.
  • Such cold extrusion presses are known per se for the production of chipboard, but for this purpose it is necessary to transfer the vertical action of the extrusion press into a horizontal feed movement of the set strand. Such a measure would be inconceivable in the production of hollow prismatic extruded profiles.
  • the invention is therefore based on the special object of enabling the production of hollow prismatic extruded profiles in a horizontal cold extrusion press.
  • the essence of the invention is that at least one further pair of stuffing slides, which can be moved from side to side and plunges into the filling area below the mandrel, is arranged.
  • This pair of stuffing slides arranged at a certain point in the filling space has the effect that when the mixture is poured in along the side surfaces of the mandrel, the accumulating mixture moves (stuffing) into the filling space area below the mandrel, in order in this way to be approximately the same around the mandrel To achieve filling densities.
  • the invention provides that the individual slide of the pair of stuffing slides has a stroke corresponding at least to the wall thickness of the extruded profile, in which case the wall thickness of the vertical web of the extruded profile is meant, provided that such a profile should have different wall thicknesses.
  • the pair of stuffing slides are assigned to each stroke of the extrusion piston. It is even conceivable that the movement of the pair of stuffing slides is different from the movement of the pair of sliders covering the filling space upwards. If the passage opening of the pair of slides is congruent with the outlet opening of the loading funnel, then the slides of the plug-and-slide pair should be in the retracted, ineffective position in which they form part of the wall of the filling space. However, if the normal closing slide is in its end positions and the filling space is covered upwards, then it is advisable to move the stuffing slides into the filling space, which can also be done in a quick, oscillating manner. This leads to the fact that the mixture introduced into the filling space during the first slide movement is preferably distributed into the filling area below the mandrel and that the next time the closing slide moves, the mixture brought into the filling space is properly built up from the bottom up.
  • the invention also offers, in the course of an embodiment variant, the possibility that when partition walls or inwardly projecting web approaches of the extruded profiles are arranged, they are directed horizontally in the piston extruder and in the plane of which additional stuffing-slide pairs reciprocate are mobile. If it is an extruded profile with a continuous partition, then this can be properly filled with the means of the invention both in the horizontal and in the vertical position. However, if there are web attachments, it is advisable to arrange them horizontally in the course of the latter feature of the invention and to provide associated additional pairs of stuffing slide valves in order to ensure proper filling of the filling space, particularly with these web attachments.
  • the extruded profile 1 according to FIG. 1 has a hollow prismatic cross section, which in this example is square, without the invention being restricted to this. It is only intended to indicate symbolically that rectangular, trapezoidal and polygonal cross-sections also belong to the consideration according to the invention; all cross-sections have in common that a prismatic cavity 4 is based, the cross-section of which may be proportional to the overall cross-section, but need not be.
  • an extruded profile 2 with a partition 6 is shown in cross section, which results in prismatic cavities 4 that are separate from one another.
  • the problem arises of producing both the partition wall and the bottom wall of the extruded profile 2 in the same condition as the other walls.
  • FIG. 3 shows an extruded profile 3 with web projections 7 projecting inwards, as a result of which an I-shaped prismatic cavity 4 is formed.
  • a filling chamber 8 of a horizontal piston extrusion press is shown in cross section.
  • This filling chamber 9 is penetrated by a mandrel 9, namely along the extrusion direction, so that, for example, an extrusion profile according to such an arrangement.
  • the filling space 8 is laterally delimited by side walls 10 which are connected to a floor 11.
  • Duderch has created a U-shaped basic profile, the upwardly open side of which is delimited by a closing slide 13 is, which separates the filling chamber 8 from a feed hopper 12 by a mixture of small plant parts and binders.
  • the small plant parts can be made from wood shavings, wood fibers, sawdust, or from agricultural waste products, e.g. B.
  • the closing slide 13 acc. Fig. 4 has a passage opening 14 which corresponds approximately to the exit cross section of the hopper 12, in which the mixed mass to be pressed is located.
  • the closing slide 13 has been adjusted so far with the aid of its symbolically illustrated lifting drive 15 that the passage opening 14 is congruent at least in a partial area with the outlet opening of the loading funnel 12, the mixture can be in the filling space delimited by the side walls 8 and the mandrel 9 8 get under the conditions of free fall.
  • stuffing slides 16, 17 with associated lifting drives 18, 19 are now provided, which can be moved back and forth in the plane of the filling space area located below the mandrel 9, as the arrows indicate.
  • This stuffing slide 16, 17 have the task of the mixture lying in front of them in the filling area to move laterally below the mandrel 9, that is to say to stuff in there.
  • the control of the stroke drives 18, 19 is selected such that when the stuffing slide 16, 17, 17 encounters considerable resistance, the stuffing slide 16, 17 is not enforced.
  • a control system is suitable such that when the passage opening 14 is passed along the filling space 8, the stuffing slides 16, 17 remain in their drawn starting position.
  • the stuffing slides 16, 17 should be moved back and forth at least once, preferably several times. It is thereby achieved that the area of the filling frame 8 located below the mandrel 9 is initially filled with the mixture that is accumulated on the side of the mandrel 9. If this is achieved, the closing slide movement 13, 15 can be continued without further movement of the stuffing slide 16, 17.
  • FIG. 5 shows an arrangement of the filling device for the production of extruded profiles according to. Fig. 2, it remains open whether the extruded profile to be manufactured a continuous partition 6 or web approaches 7 acc. 2 and 3.
  • stuffing slides 16, 17 with their drives 18, 19 are the same as in FIG. 4.
  • additional stuffing slides 20, 21 are also assigned in the horizontal plane of the partition walls 6 or the web extensions 7 (see FIGS. 2 and 3)
  • Lift drives 22, 23 are provided, which have the task of stuffing the mass located on the side of the mandrels 9 into the space between the mandrels 9.
