Definitions

  • the invention relates to a device for shredding plastic parts, in particular foamed plastic, such as Foam consisting of a rotating holder.
  • a device of the type mentioned is known from the prior art according to US-PS 27 39 647 under the name cutting mill.
  • the cutting mill described there consists of a rotor attached to a shaft, which has a plurality of blades which are arranged on the rotor at the same distance from one another.
  • Such cutting mills are extremely questionable from the point of view of environmental protection, since they are noisy and require a high energy requirement for operation; there is also a high level of dust formation, particularly when shredding foam. Such dust can not be processed, but must be treated as non-recyclable waste and thus pollutes the landfill.
  • the rotating holder essentially consists of a shaft rotatably mounted in a frame, which has two rotatable axes perpendicular to the shaft for receiving the knife band, at least one of these axes having a drive for the knife band. According to an advantageous embodiment, the distance between the two axes can be changed, which enables the knife band to be clamped or re-tensioned.
  • the axes each have a groove-provided wheel for guiding and receiving the knife band.
  • the knife band is ground on both sides, so that the foam is cut by the knife band at a rotation of 180 degrees from the other edge of the knife band. This increases the service life of the knife belt or increases the throughput of shredded plastic, in particular foam.
  • the invention also relates to the use of the device for comminuting plastic parts, in particular plastic, such as Foam, consisting of a rotating holder, which has a circumferential knife band, for attachment to a cutting device for producing strips of plastic, which has two mutually opposite shafts arranged opposite one another on a frame provided with a support surface, each rotating several vertically and have circular knives arranged parallel to one another (US Pat. No. 2,739,647).
  • plastic such as Foam
  • a conveyor belt Downstream of these circular knives is a conveyor belt to which the device according to the invention for comminuting plastic parts, in particular foam, is connected.
  • the conveyor belt can be integrated into the support surface, the device for comminuting plastic parts directly adjoining the support, so that the support surface forms the counter bearing for the rotating knife belt during cutting.
  • the drawing shows the entire device in a plan view.
  • the device itself consists of a frame, designated overall by 1, which has a bearing surface 1a and which has the cutting device 2, which consists of two mutually opposite rotating shafts 3, 4, each with several circular knives 5, 6 arranged parallel to one another are provided.
  • this cutting device for example, plastic plates inserted in the direction of the arrow X are cut into strips. These strips are picked up by the conveyor belt 7 arranged downstream of this cutting device 2 and integrated in the support surface 1a of the frame, and fed to the device according to the invention for comminuting plastic parts, in particular foamed plastic, such as foam.
  • This designated 8 device consists of a rotatably mounted in the frame 1 bracket 9, in the form of a shaft, for example, which has two spaced axes 10 and 11 perpendicular to the shaft, each having a wheel 12, 13 with grooves 12a, 13a for receiving the knife band 14.
  • the contact surface 1a extends up to the device and forms the counter bearing for the rotating knife band 14 of the rotating holder 9.
  • the axis 11, which is driven by the motor 15, is held in a longitudinally displaceable manner by the holder 9 in an elongated hole 16, so that the distance between the two axes 10 and 11 can be changed. As a result, the clamping of the knife band 14 is facilitated or its retensioning is made possible.
  • This clamping device consists of a screw 18 which is held by a nut 19 and which is rotatably connected to the axis 11. By adjusting the screw 18, the axis 11 can now be moved along the elongated hole 16.
  • the motor 20 is provided as the drive for the holder 9.
