Definitions

  • the invention relates to a device for spreading spreading material on a continuously moving base according to the preamble of patent claim 1.
  • rotating disk rollers or spiked rollers which have rows arranged on the circumference spike, which engage between the spiked rows of the opposite roller.
  • Fiber bale opening rollers are known, which are driven in opposite directions rotating.
  • the rollers are designed as disc shafts with attached toothed disks. These toothed disks have so-called Auflösezähne, which are set counter to the direction of rotation sawtooth-like, wherein the opening teeth of the rollers mesh and form a meandering gap.
  • a device for spreading matte grit on a moving surface in which an arrangement of disk rolls is provided. These disk rollers are all driven in the same direction rotating and form scattering chambers for grit of different grain size. In addition to the classification of the components of the grit, foreign bodies such as glue lumps, splinters and so forth are discharged behind the disk roller and collected in a gutter.
  • a cover layer spreading device which has a screening device below a blow register, which comprises a vibration drive.
  • a screening device below a blow register, which comprises a vibration drive.
  • Object of the present invention is therefore to develop a device for spreading of grit in such a way that a high quality wood-based material board can be produced and damage to device parts of the production plant for the production of wood-based panels are avoided.
  • the rollers are arranged such that one through the center axes of the rollers extending plane to a horizontal plane has an angle of 30 ° to 90 °, preferably 45 ° to 75 °.
  • the particles of the stream are pulsed during the passage between the rollers and charged depending on their specific weights with different kinetic energy. Depending on the kinetic energy of the particles of the material flow, the particles of the material flow move in a different pitch parabola from the opening roller assembly, so that unwanted foreign bodies can be separated from the rest of the material flow.
  • FIG. 1 schematically is a forming station with at least one dosing bunker 1, which has a Austragswalzenan kann 2, an opening roller assembly 3, a scattering head assembly 4 and a forming belt 5 shown.
  • the opening roller assembly 3 consists of two below the Austragswalzenan für 2 superimposed rollers 6,6 'wherein the rollers 6, 6' are arranged axially parallel and wherein a through the central axes of the rollers 6, 6 'extending plane 7 to a horizontal plane 8 an angle ⁇ 9 from 30 ° to 90 °, preferably from 45 ° to 75 °.
  • rollers 6, 6 ' as disclosed by the prior art described above, may be formed as toothed disc or spiked rollers.
  • the forming station is preferably provided for the production of sheets of lignocellulosic and / or cellulose-containing particles of different sizes, such as fibers, chips and the like.
  • glued fibers are discharged continuously as a material flow over the discharge roller arrangement 2 over a predetermined width and are fed onto the opening roller arrangement 3.
  • the rollers 6, 6 ' as shown by the arrows 10, are driven in opposite directions in rotation, wherein the rollers 6, 6' for dissolving fiber aggregates have elements which interact in an interlocking manner during rotation.
  • the flow of material emanating from the Austragswalanzanorndung 2 trickles down by gravity and meets at low speed on the rollers 6, 6 '.
  • These rotate at very high speeds of 600 to 3000 revolutions per minute, preferably 800 to 1200 revolutions per minute, thus accelerating the impinging particles of the material flow to the peripheral speed.
  • the fabric particles of the stream are conveyed as toothed disk rolls or spiked rolls which rotate in opposite directions to one another, through the gap remaining between the rolls 6, 6' and are thus catapulted out of the opening roll arrangement 3 at this speed.
  • an air stream is also drawn through the opening roller assembly 3.
  • This air stream expands immediately behind the opening roller assembly 3, causing a rapid deceleration of the air speed.
  • the light particles are delayed by their low kinetic energy along with the air flow.
  • Foreign bodies with a higher specific gravity on the other hand, have a considerably higher kinetic energy and slow down their speed very slowly.
  • the particles of the material flow move in a different pitch parabola from the opening roller assembly, so that unwanted foreign bodies can be separated from the rest of the material flow.
  • the material flow emerges from the opening roller arrangement 3 essentially in the horizontal direction.
  • gravitational forces of the flow moves in a parabola of the opening roller assembly 3.
  • the unwanted foreign bodies that leave the opening roller assembly 3 at high speed in a flat parabola are in a separated separate shaft 11, and thus separated from the rest of the flow.
  • the material stream strikes the scattering head arrangement 4 arranged below the opening roller arrangement 3 and is subsequently scattered onto the forming belt 5 to form a fleece 12.
  • Fig. 2 1 schematically shows a further embodiment of a forming station with dosing bunker 1, an opening roller arrangement 3, a spreading head arrangement 4 and a forming belt 5 onto which the material web 12 is sprinkled from glued fibers.
  • the material stream of glued fibers is temporarily stored and distributed to an intended discharge width and discharged downwards over the entire width of the dosing hopper 1.
  • the material flow is then applied to the opening roller assembly 3, which consists of two oppositely rotating driven rollers 6, 6 '.
  • the rollers 6, 6 ' are, as it already is FIG.
  • opening cylinder assembly 3 As opening cylinder assembly 3, all known by the prior art opening rollers can be used, which are suitable to dissolve Streugutverdichtungen of streams and glue knots.
  • opening roller assembly 4 As opening cylinder assembly 3, all known by the prior art opening rollers can be used, which are suitable to dissolve Streugutverdichtungen of streams and glue knots.
  • an additional conveying device 13 is provided below the opening roller assembly 3, which supplies the material flow of a spreading head assembly 4.
  • the additional conveyor 13 is designed as a feeder belt, which continuously promotes a controllable flow rate in the spreading head assembly 4, so that depending on the plate thickness and width of the scattering head assembly a predetermined amount is strewn on the forming belt 5.
  • the conveying direction of the forming belt 5 is shown here by the arrow 14.
  • the fiber opening roller arrangement 3 could also be arranged between the conveying device 13 and the spreading head arrangement 4.
