Abstract

The invention relates to a device on a spinning room preparation machine, for example a cleaner, a carding machine or the like, for opening and cleaning fibre material, especially cotton. The device comprises an opening roll arranged downstream of a feed device. The feed device comprises at least one intake roll, with which at least two separating blades or separating edges for impurities are associated. The separating blades or separating edges are directed against the direction of rotation and have associated separating openings. When seen in the direction of rotation of the opening roll, the first separating blade that is adjustable relative to the outer periphery of the roll is provided and a guide element is arranged upstream of the second separating blade. In order to improve the degree of separation of foreign bodies and reduce the proportion of good fibres in the waste, the first separating blade can be displaced substantially along a tangential direction with respect to the outer envelope of the opening roll, and the space from the edge of the first separating blade relative to the transfer point between the intake roll and the opening roll can be adjusted.

Description

Be positioned at the device for shredding and cleaning fibre material on spinning room draft machine

Technical field

The present invention relates to a kind of for shredding and clean especially cotton fibrous material, be positioned on spinning room draft machine such as cleaner, the device of carding machine etc., described device has opening roller, described opening roller is arranged in the downstream of feed arrangement, described feed arrangement comprises at least one input roller, at least two separating sheet or separation edge for impurity are associated with described opening roller, described separating sheet or separation edge portion are along the direction orientation contrary with direction of rotation and have the separated opening being associated, wherein, when the direction of rotation along opening roller is observed, be provided with the first separating sheet that can adjust with respect to the periphery of roller, and induction element is arranged in the upstream end of the second separating sheet.

Background technology

In carding machine and cleaner, use the separating sheet for waste material, refuse or dust.On cleaner, this separating sheet is combined with sawtooth roller.On carding machine, separating sheet is located use and be combined with discharge closure or delivery pipe at licker-in and at cylinder (drum), and the task of described discharge closure is that the separated refuse of separating, staple fibre and dust granule in air-flow are seen off.This separating sheet is arranged in fixed position, that is, the position of separating sheet, separating sheet end are invariable during machine run with respect to the position, angle of the tangent line of cylinder with respect to the interval of roller (cylinder) and the separated flank of separating sheet.Therefore it is conventionally very difficult and only have when machine is static and can carry out that disadvantage is to revise these setup parameters.Separating sheet edge (end) can be for example between 0.2mm and 0.6mm according to the fibrous material of processing with respect to the interval of the saw-tooth clothing on licker-in.When machine is static, use so-called spacing meter that interval can be manually set.Conventionally it is desirable to adjust separating sheet, thereby adapt to heterogeneity and the type of different materials, especially pollutant.

In known devices (EP0952244A), the requirement that the first separating sheet is arranged on holding element and processes according to combing is set it with respect to the interval of pin tip circle (circumference), and described separating sheet is arranged to respect to the tangent line of tip circle at angle.Disadvantage is along the direction setting interval towards opening roller.In the relatively large situation in interval, the ratio of the good fiber in waste material increases undesirablely.Another problem is that the first separating sheet is arranged in fixed position, and this also can increase the ratio of good fiber in waste material.

Summary of the invention

Therefore, the present invention is based on the problem of the device that Known Species is provided, this device has been avoided described shortcoming, wherein, especially, has improved the separation degree (clean-up performance) of segregating foreign objects.

Feature by claim 1 solves described problem.

Due to the measure of taking according to the present invention, in the situation that the fibrous material of processing changes, can be before operation and operating period in simple mode, realize optimal separation.In machine run, advantageously implement displacement, reason is by monitoring separation or by measuring separated flow, can realizing accurately and repeatably separation.

According to the present invention, advantageously can adjust separating sheet with respect to the interval of branchpoint (operating point).With respect to the tangential linearity adjustment of implementing the first separating sheet of opening roller.Can be adapted to different fibrous materials and pollutant.Especially, optimize shared ratio and the optimization clean-up performance of good fiber in dirt.

Claim 2 to 20 comprises favourable improvement of the present invention.

rotation.Input roller

3,4 and feed roller 5,6 form 4 roller input blocks.A pair of

input roller

3,4 forms the base portion of feed shaft 1 and to opening roller 7 feeding fibrous materials, described opening roller 7 along the direction of arrow 7a with High Rotation Speed.Two

input rollers

3 and 4 in a similar fashion by fibrous material aggegation to hopper, from feed shaft, part 2 is regained fibrous materials and is fed into opening roller 7.The pin or the needle-like piece 7b(that along direction of rotation 7a, tilt are shown in Fig. 1 b) in the surrounding of the periphery of opening roller 7, catch fibrous material and make described fibrous material see that with the clamping zone 8(of a pair of

input roller

3,4 Fig. 1 is a) separated.Between input roller 3 and opening roller 7, be provided with the first branchpoint 9 for fibrous material.Input roller 3 and opening roller 7 be arranged to be spaced from each other and its direction of

rotation

3a and 7a opposite each other.Between input roller 4 and opening roller 7, be provided with the second branchpoint 10 and its direction of rotation 4a and 7a mutually the same.

Direction of rotation along opening roller 7 is observed, and the first separating sheet 11 and the second separating sheet 12 are associated with opening roller 7.The first separating sheet 11 along be substantially tangential to opening roller card clothing 7b the arrow A of tip circle 7c, the direction of B can be shifted.Can adjust the first separating sheet 11Pian edge 11a and see Fig. 2 with respect to the interval a(of the branchpoint 9 between input roller 3 and opening roller 7).Interval a represents the size of the separated opening between the first separating sheet 11 and branchpoint 9 simultaneously.

Upstream end in the second separating sheet 12 is furnished with induction element 13, described induction element 13 by an end pivot be arranged in pivot bearings 21, to can adjust induction element 13 with respect to the tip circle 7c interval of opening roller 7.Between the free end of separating sheet 12 and induction element 13, be provided with separated opening 14.

The first separating sheet 11 and the second separating sheet 12 are arranged on respectively and keep on section bar 15 and 16, and described maintenance section bar 15 and 16 is for example made by extruded aluminum and extended on the working width of machine.Reference numeral 17 and 18 represents for discharging the discharge closure of isolated waste material.
