Definitions

  • the invention relates to a cleaning machine for textile fibers transported in a conveying air flow, with a horizontal opening roller, which has a roller body and impact elements protruding from the peripheral surface of the roller body, with bar grids arranged under the underside of the opening roller and with an inlet and an outlet for the conveying air stream which are arranged at a first or at a second end of the opening roller.
  • At least one such cleaning machine is known and available on the market. It serves to dissolve the fiber flakes supplied in the conveying air flow and to remove impurities from them. The fiber material is dragged over the slatted frames, with contamination from the slatted frames step through and then be vacuumed.
  • bale removal machines for example of the type sold by the applicant worldwide with the designation "UNIFLOC"
  • transfer a relatively uniform flock flow to the subsequent conveying air flow but that smaller clumps of fiber flocks can arise again in the course of pneumatic conveying , which have to be dissolved again by the cleaning machine according to the invention before the actual function of this machine, namely the further dissolving of the flakes released by the bale removal machine, can be carried out.
  • the object of the invention is therefore to design the cleaning machine specified at the outset in such a way that there is an improved dissolving effect from the first to the second end of the dissolving roller, as a result of which better separation of impurities is achieved in comparison with the known machine.
  • the object is achieved according to the invention in that the diameter of the roller body increases from the first to the second end of the opening roller.
  • the fiber flakes transported in the conveying air flow are increasingly dissolved by the action of the cleaning machine. Because the length of the striking elements can be changed in length from the first to the second end of the opening roller, the length of the striking elements is better adapted to the increasing degree of dissolution of the fiber flakes, which depends on the material to be processed. which results in the desired improved effect.
  • the cleaning machine shown in FIGS. 1-3 has an opening roller 13 with a roller body 1, which is rotatably mounted in a housing 2 about a horizontal axis.
  • the roller body 1 carries striker pins 3 which protrude from the peripheral surface 4 of the roller body 1.
  • the opening roller 13 is rotated in operation by a drive motor, not shown, in the direction of the arrow according to FIG. 1.
  • a drive motor not shown
  • two bar grids 5 and 6, only shown in FIG. 1 are arranged.
  • the housing 2 Above the top of the opening roller 13, the housing 2 has at a first end of the roller, on the right in FIGS. 1 and 3 or at the bottom in FIG. 2, an air inlet 7 and at a second end of the roller, on the left in FIGS.
  • FIG. 2 the positions of the inlet 7 and the outlet 8 and in Figures 3 and 4, the positions of the outlet 8, which are not visible here, each indicated with a broken line.
  • baffles 9, 10 and 11 Arranged between the inlet 7 and the outlet 8 above the top of the opening roller 13 are three baffles 9, 10 and 11 which are inclined to the axis of the roller and which delimit two transfer chambers between the top of the roller 13 and the upper wall of the housing 2.
  • the textile machine flakes to be cleaned and dissolved are fed in a conveying air flow through the inlet 7.
  • the conveying air with the fiber flakes essentially flows first around the underside of the rotating opening roller 13, then through the transfer chamber between the guide plates 9 and 10, which moves the air in the direction of the axis of the opening roller 13, then again around the underside of the roller, then through the transfer chamber between the guide plates 10 and 11 and again around the underside of the roller in order to finally leave the machine through the outlet 8.
  • the diameter of the roller body 1 increases from the inlet 7 to the outlet 8.
  • the radial length of the striker pins 3 at the outlet 8 can still be 25-75%, preferably about 50%, of the radial length of the striker pins 3 at the inlet. It cannot be ruled out that, for example, some of the striker pins 3 have a reduced length at the inlet.
  • the free ends of the striking pins 3 can lie at least approximately in a circular cylindrical surface coaxial with the roller body 1. This means that the free ends of the striker pins 3 are all substantially the same distance from the axis of the roller body 1 (although it cannot be ruled out that some of the striker pins 3 could be shorter, so that their free ends are a smaller distance from the axis of the roller body 1 to have).
  • the roller body 1 shown in FIGS. 1 to 3 is conical, so that its diameter gradually increases from the inlet 7 to the outlet 8.
  • the radial length of the striker pins 3 gradually decreases from the inlet 7 to the outlet 8.
  • the length of the striker pins 3 could also gradually decrease in such a way that one group of the striker pins each has the same length, a next group of the striker pins has a somewhat smaller length, etc.
  • FIG. 4 shows an embodiment with a roller body composed of two cylindrical sections 1a and 1b.
  • the section 1a located at the inlet 7, or on the right in FIG. 4 has a smaller diameter than the section 1b on the left in FIG. 4, and the striking pins 3 arranged on section 1b have a smaller radial length than the striking pins arranged on section 1a 3, again in such a way that the free ends of essentially all striking pins 3 lie at least approximately in a circular cylindrical surface coaxial with the roller body 1a, 1b.
  • the sections 1a and / or 1b could additionally be slightly conical.
  • the roller body could also be composed of more than two sections with diameters increasing from the inlet to the outlet.
  • the fiber flakes supplied with the conveying air flow through the inlet 7 are, as mentioned, increasingly dissolved on the way to the outlet 8 in the cleaning machines described.
  • the striking pins 3 are adapted to the increasing degree of resolution by their length, which decreases from inlet 7 to outlet 8.
  • the density of the striking pins can advantageously be increased with the increasing degree of disintegration of the fiber flakes, i.e. the axial distances between adjacent striking pins 3 can, as shown, be smaller at outlet 8 than at inlet 7, for example in a ratio of 2: 3.
  • the thickness of the measured in the direction of the axis of the roller body 1 or 1a, 1b Remove the impact pins 3 from the inlet 7 to the outlet 8, so that the impact pins 3 at the outlet 8 are thinner than at the inlet 7, for example also in a ratio of about 2: 3.
  • this thickness is equal to the diameter of the same; but the striking pins 3 can also have other cross-sectional shapes, for example square, rectangular, etc.
  • other striking elements can also be used, for example plate-like elements made of sheet metal.
  • the opening roller 13 can have the following dimensions: Length of the roller body 1 about 1.6 m, diameter of the roller body 1 at the inlet 7 about 65 cm, at the outlet 8 about 70 cm, radial length of the striking pins 3 at the inlet 7 about 5 cm, at the outlet 8 about 2.5 cm, diameter the striker pins 3 about 1 cm (possibly from the inlet 7 to the outlet 8 decreasing from 1.2 to 0.8 cm) axial distance between adjacent striker pins about 2.5 cm (possibly from the inlet 7 to the outlet 8 decreasing from 3 to 2 cm).
  • the variants shown with FIGS. 5 and 6 relate to the length of the striking pins 3, in that in these two variants the striking pins have the same length over the entire length of the roller body 1, for example 3.5 cm.
  • the dissolving effect on the above-mentioned agglomerations of fiber flakes is somewhat reduced at the beginning of the processing process, ie it becomes somewhat less aggressive than in the embodiments according to FIGS. 2-4.
  • This is essentially desirable when cotton with rather longer fibers is processed in order to avoid the danger as possible when the agglomerations mentioned are dissolved avoid forming nits, where nits are small knots of fibers.
  • FIGS. 7 and 8 show an even more consequent reduction in the aggressiveness of the striking pins 3 at the beginning of the process, in that the length of the striking pins 3 increases from the beginning of the processing process to the end.
  • This increase can be, for example, 25% - 100%.
  • the striking pins can be 2.5 cm at the beginning of the processing process and 5 cm at the end of the process.
