Definitions

  • the invention relates to a document shredder according to the preamble of patent claim 1.
  • the object of the present invention is therefore also to carry out a structural design on such document shredders, which ensures that the clippings are always transferred from and to the conveyor belt without any problems, both in the case of roll forward and roll return.
  • the document shredder according to FIGS. 1 and 2 has a feed table 5 arranged in front of the pair of cutting rollers 1, 2 together with the associated wipers 3 and their holding rods 4 passing through the cutouts 3a for receiving the material to be shredded or shredded.
  • a motor-driven conveyor belt 6 is mounted in this feed table, which extends into the area of the Feed gap "E" for the material to be cut.
  • the guide device 8, 9 consists of a cross member 8 which extends over the entire width of the cutting unit and is fastened in the side bearing plates 11 of the cutting unit and has a material guide member detachably mounted thereon 9 to 9c there is that the conveyor belt 6 has longitudinal ribs 6a arranged on its surface at a mutual distance "B" from one another and the actual material guide member 9 of the guide device 8, 9 has comb-like recesses 9a in the area of these longitudinal ribs, the same being the ones located between the longitudinal ribs 6a, projecting sections 9b with their tips 9c like peeling edges tangential to the upper conveyor belt area "X" on the belt surface.
  • the comb-like material guide member 9 to 9c is detachably connected to the cross member 8 and the latter is fastened in the lateral bearing plates 11 of the cutting unit and that the region 3b of the stripper plates 3 adjacent to the conveyor belt 6 is one has the cross section of the cross member 8 adapted recess 3a.
  • FIGS. 1 and 2 an alternative embodiment to FIGS. 1 and 2 is shown in FIG , in which the surfaces 3b 'of the back parts 3b of the stripper plates 3 are higher by a certain dimension "y" than the surface 9' 'of the material guide member 9' fastened on the cross member 8 'there;
  • the peeling point 3c advantageously lies in the area near the outer contour of the associated cutting disk 2.
  • the surfaces 3b 'of the back parts 3b of the wiper plates 3 are higher by a certain dimension "y" than the surface 9' 'which is flat in this case. of the material guide member 9 'fastened on the cross member 8', and that the cross member 8 or 8 'made of steel and the material guide member 9 to 9c or 9', 9 '' consist of wear-resistant plastic.
