Definitions

  • the invention relates to a roller mill for grinding grain and. the like to flour, Semolina, haze, etc. It is particularly directed to the overdrive in such roller mills with at least one pair of rollers with corrugated or smooth rollers.
  • Roller mills for grinding grain usually contain two or four pairs of rollers, like this B. is described in DE-C-2730166 or in EP-B-334919.
  • the rollers of a pair of rollers rotate in opposite directions and with different ones Speed to achieve crushing and grinding of cereal grains.
  • the nip can usually be varied.
  • a similar solution is described in DE-A-3304832 for a roller mill.
  • a double-sided Toothed belt runs around the pulleys of the rollers and continues to run around one Toothed belt pulley of the drive and a loose pulley.
  • GB-A-1460628 discloses a belt drive for variable speeds an adjustable deflection pulley for two belts on a sliding carriage in a swiveling arm. Inaccuracies in the alignment of the arm can can be corrected by eccentrics on the axes of rotation.
  • V-toothed belts Another toothed belt overdrive using V-toothed belts is also known according to ITPS 1198054 and EP-B-425626 or WO-A-90/14165.
  • the latter describes a roller mill with at least one pair of rollers, the Wave of slower running Roller carries a disc, the teeth with grooves parallel to the axis and the includes a drive device through a third traction sheave which is in position is adjustable, is kept under tension.
  • the adjustability of the whole Disc is realized using set screws or eccentrics.
  • Even the faster one Roller is provided with a disc that has teeth with grooves, these however, are arranged at right angles to the shaft axis.
  • the drive device itself is an outside and inside profiled belt that fits into the profiles of the above three Engages discs appropriately, d. H. with a tooth or wedge profile.
  • the disks are designed so wide that usually three straps are placed in parallel. These are after the aforementioned State of the art tensioned together and wear unevenly. An even one Tensioning is very complex and not completely possible. Also a previous one Reading and measuring cannot solve the problems.
  • the invention is therefore based on the object, the disadvantages of the prior art the technology as far as possible and a uniform tensioning of the individual Belt and thus to achieve even wear.
  • a 4-roll mill 1 with a housing 2, as z. B. described in DE-C-2730166 is, in addition to the, not explicitly shown feed and discharge devices for the regrind u. a.
  • two pairs of horizontally mounted rollers 3, 3 ', 4, 4', on their Ends are provided with a disc 5 and a second disc 6.
  • the nip of a pair of rollers 3, 4 or 3 ', 4' can be changed by motor or by means of manual adjustment 7 become.
  • Two commercial belts 9 profiled on both sides run around the Discs 5, 6 and the tensioning disc 18.
  • the belts 9 preferably have an inside with a multi-wedge profile in the longitudinal direction and a tooth profile on the outside transverse to the longitudinal direction.
  • the tensioning pulley 18 of the tensioning roller 8 has separately adjustable sections 14, 15, wherein the inner portion 14 by means of a screw 13 and the outer section 15 is adjusted by means of an eccentric 19.
  • the eccentric 19 is fixed via a nut 17.
  • a screw 16 fixes a shaft.
  • the sections 14, 15 are preferably held by roller bearings 20.
  • rollers of a pair 3, 4 or 3 ', 4' are in a so-called roller package, such as it is described in DE-C-2730166.
  • the rollers are in bearing bodies 10, 10 ', the bearing body 10' being connected to a frame support 11.
  • This roll package is in a manner not shown in detail on a base of the Housing 2 arranged.
  • the grinding gap setting device 12 is also a foreign body or overload protection trained.
  • roller mill 1 which is mainly used in the milling, run the rollers of a pair with different speeds and a specific roller gap against each other. Thus, not only pressure, but also friction and Shear effect on the regrind.
  • a main drive not shown on one side of the roller mill 1 one of the two rollers of the pair drives directly, generally the faster roller 4, 4 '.
  • the slower roller 3, 3 ' is during the grinding process pulled over the product by the faster roller 4, 4 '.
  • an overdrive (belt 9) with different Washer diameters used. Since the pair of reels rotate in opposite directions, the first pulley 5 must be arranged outside the belt 9. Because of the adjustable roller gap (and thus also the center distance of the rollers) a tension roller 8 must be provided.
  • the second disc 6 and the clamping disk 18, however, have a flat profile or a wedge-groove profile in Circumferential direction on or a tooth profile perpendicular to the axis of the roller 4 (4 ').
  • Pulley and belt profiles are matched to each other. Between the first disc 5 and belt 9 is positive and between belt 9 and pulley 6 or Spring washer 18 friction or frictional connection.
