Definitions

  • the invention relates to a cleaning machine for textile fibers transported in a conveying air flow, with a horizontal opening roller, equipped with impact elements, under the underside of which there are arranged approximately parallel grate bars which are adjustable in their angle of attack.
  • Such a cleaning machine is known, for example from GB-A-2 053 995, and is available on the market, and it is also known that the grate bars, usually profiled bars, can be pivoted in order to change their angle of attack about axes parallel to their longitudinal axes make to allow adaptation to different textile fiber material.
  • This known setting option allows however, only an adjustment that is the same for all grate bars, ie in a relatively limited range.
  • the object of the invention is to design the cleaning machine specified at the outset so that better adaptation to different textile fiber materials is possible in a further range of properties thereof.
  • the grate bars at one end of the group can be adjustable differently, with respect to the roll, and possibly also pivotable differently than the grate bars at the other end of the group.
  • the cleaning machine shown has an opening roller 2, which is usually equipped with striking pins 1 and which is rotatably mounted in a housing 3 about a horizontal axis.
  • the opening roller 2 is rotated in operation by a drive motor, not shown, in the direction of the arrow according to FIG. 1.
  • the housing 3 Above the top of the opening roller 2, the housing 3 has an inlet 4 and an outlet 5 for a conveying air flow that transports textile fibers in flake form.
  • the inlet 4 is arranged at one end of the roller 2, while the outlet 5 is arranged at the other end of the roller 2.
  • baffles 6, 7 and 8 Arranged between the inlet 4 and the outlet 5 above the top of the opening roller 2 are three baffles 6, 7 and 8 which are inclined to the axis of the roller and which delimit two transfer chambers between the top of the roller 2 and the upper wall of the housing 3.
  • a template designed and movable like the template 12 is assigned to each end of each of the groups of grate bars 9, 10, 11.
  • the grate bars of each group 9, 10, 11, etc. each have a crank arm 40 at one end, which is articulated on a common angle control element.
  • the crank arms 40 of the group of Grate bars 9 are articulated on an angle control template 41
  • the crank arms 40 of the group of grate bars 11 are articulated on an angle control template 42.
  • the template 41 and a further angle control template 43 which is assigned to the group of grate bars 10 (FIG. 1), are also shown in FIG. 3, in which the crank arms are identified by 40.1.
  • the crank arms 40 are also shown on one end 9.1 resp. 10.1 of the outermost grate bar of the group of grate bars 9 resp.
