Definitions

  • Cutting device for a granulator for cutting granules of plastic strands emerging from nozzles with a knife rotor
  • the invention relates to a cutting device for a granulator for cutting granules emerging from nozzles plastic strands with a knife rotor, which is connected via a Ge ⁇ guide piece with drive part and the knife rotor supporting output part with a drive shaft.
  • a cutting device is described in DE 103 21 723 A1.
  • the invention has for its object to build a cutting device, in which also a gimbal-acting joint piece can be used, which is characterized by a particularly simple structure.
  • This is done in accordance with the invention in that the drive part is inserted into a ball head in a matching spherical cap in the stripping section and the ball head is penetrated by at least one direction axis about which the ball head in the spherical cap with axial offset of the drive part and driven part is rotatable, said from the ends of the directional axis emerging from the ball head are each mounted in a groove extending in the spherical cap, the transverse to the direction of rotation of the driven spherical cap substantially in the direction of the driven part, that shift in offset from drive part to output part, the ends move in the grooves in the driven part.
  • the cutting device is advantageously designed so that the ends of the direction axis rotatably protrude into a respective sliding block, which is displaceable in the groove adapted to it in the Kugelgelenkkalotte.
  • Figure 1 shows the cutting device in section
  • Figure 2 is a perspective view of the exploded parts of the shown
  • FIG. 3 shows a section similar to that of FIG. 1 with a detailed view of the ball head with a directional axis;
  • FIG. 4 shows the cutting device according to FIG. 1 assembled in a perspective view
  • Figure 5 is an axial view of the cutting device according to Figure 1;
  • FIG. 6 shows a ball head in section with the knife carrier with two mutually perpendicular direction axes.
  • Figure 7 shows the arrangement of Figure 6 in a perspective view with pulled apart
  • the cutting device shown in section in FIG. 1 has the drive shaft 1, which merges directly into the drive part 2.
  • the drive part 2 is inserted into the ball head 3 and fixed by means of the screw 4 to the drive shaft 1.
  • the ball head 3 is seated in the spherical cap 5, in which the ball head 3 can be arbitrarily adjusted with respect to its axial direction.
  • the spherical cap 5 as the output part forms with the knives attached to her 6 a knife carrier, which is rotated relative to the opening of a nozzle plate 7 nozzles 16 and thereby cuts in a known manner from the nozzle 16 exiting strands into granules.
  • the hinge assembly shown in Figure 1 is provided by an automatically acting during operation alignment between the drive shaft 1 and nozzle plate is possible.
  • the individual parts of the cutting device shown in Figure 1 are shown in a perspective view and exploded in Figure 2. It can be seen that the drive shaft 1 with its drive part 2 in the ball head 3, from which protrude perpendicular to its longitudinal axis, the two ends 8 and 9 of a direction axis, each in a sliding block 11 and 12 protrude and this in axis displacement of the ball head 3 take along accordingly.
  • the recessed into the spherical cap 5 grooves 13 and 14 are provided, in which the sliding blocks 11 and 12 are displaceable in the axial direction of the spherical cap 5.
  • the design of Figure 1 is shown in a different cutting position, wherein the section through the grooves 13 and 14 extends, each receiving an axle 8 and 9 and allow its displacement in the axial direction of the ball head 3.
  • FIG. 3 The design according to FIG. 3 is shown in a perspective view in FIG. 4, which shows how the drive shaft 1 acts on the spherical cap 5 via the sliding blocks 11 and 12.
  • Figure 5 shows the arrangement of Figure 4 in an axial view of the drive shaft 1, which, as shown above, acting on the sliding blocks 11 and 12 and thus the spherical cap 5 accordingly entrains, whereby the orientation of the drive shaft 1 and the spherical cap 5 automatically results with the knives attached to her 6.

Abstract

Dispositif de coupe pour un granulateur permettant d'obtenir des granulés par découpe de joncs de matière plastique sortant de filières (8) et doté d'un rotor à lames (6) qui est raccordé à un arbre d'entraînement (1) par l'intermédiaire d'un élément d'articulation présentant un élément d'entrée et d'un élément de sortie portant le rotor à lames. L'élément d'entrée (2) est introduit dans une tête sphérique (3), située dans une calotte sphérique (5) adaptée à cette dernière, dans l'élément de sortie (15), et la tête sphérique (3) est traversée par au moins un axe de direction autour duquel la tête sphérique (3) située dans la calotte sphérique (5) peut tourner en cas de décalage axial de l'élément d'entrée et de l'élément de sortie (15). Les extrémités (8, 9) de l'axe de direction, qui sortent de la tête sphérique (3), sont situées respectivement dans une rainure (13, 14) s'étendant dans la calotte sphérique (5), ladite rainure s'étendant transversalement au sens de rotation de la calotte sphérique (5) entraînée, sensiblement en direction de l'élément d'entrée, de sorte que les extrémités (8, 9) se déplacent dans les rainures (13, 14) dans l'élément de sortie (15) en cas de décalage de l'élément d'entrée (2) par rapport à ce dernier.
