The specific embodiment
Just the drafter 1 shown in the part is made up of drivable bottom roll basically in Fig. 1 and 2, and they are furnished with the pressurization roller that can compress and they will be drawing to the fineness of hope by the fiber strip 2 that staple fibre constitutes along throughput direction A.Only show the roller that constitutes by bottom roll 3 and pressurization roller 4 to 3,4.Right at roller, what arrange before 4 is that an apron roller is right, and it only shows the apron that is made up of guiding apron 5 and 6 to 5,6.Guiding apron 5 and 6 is used in a manner known way to fiber strip 2 is led.Jaw line 7 places after the main drawing area of drafter 1 between bottom roll 3 and pressurization roller 4 finish the drawing-off to fiber strip 2.The fiber strip 2 of accomplishing drawing-off is then through compressional zone 8, and it is compressed in this compressional zone and is fine and close.By 9 restrictions of jaw line, this jaw line is formed by second a pressurization roller 10 with bottom roll 3 configurations at outlet side in compressional zone 8.Then after jaw line 9, can apply its twisting to fiber strip 6, thereby form finished product yarn 11.
Drafter 1 can be the part of a weaving loom, and yarn 11 is for example through air nozzle or encircle ingot it is twisted in this weaving loom.Under the situation of RING SPINNING loom, a plurality of drafters 1 are arranged each other side by side and bottom roll 3 is configured to the bottom roll that vertically passes through along machine.The pressurization roller 4 of two adjacent drafters and 10 can be configured to two pressurization rollers through a common axle 12 respectively in known manner.Pressurization roller 4 with all the other pressurization rollers that do not illustrate of drafter 1 be fixed on one can rotating pressurizing frame 13 on.Pressurizing frame 13 only schematically illustrates and can upwards swing around a swinging axle that does not illustrate, thereby pressurization roller 4,10 is removed from bottom roll 3.In order to eliminate the operation troubles in drafter 1, need remove pressurization roller 4,10 frequently.Pressurization roller 10 can be fixed on the pressurization roller 4 through a matrix with the mode that does not illustrate, thereby pressurization roller 4 and 10 forms a pressurization roller component.The roller 4 that perhaps pressurizes also can directly be fixed on and load on the support 13.
On pressurization roller 4, arrange compression unit 14, it has two mechanisms 15 and 16 that are used for the deflected fibers yarn.The mechanism 15 that is used for the deflected fibers yarn with 16 on throughput direction apart from one another by.First mechanism 15 that is used for deflection is arranged on jaw line 7 and is arranged on after the jaw line 7 with second mechanism 16 that is used for deflection before.Each be used for deflection mechanism 15 or 16 all dispose a recessed cylindrical so bearing- surface 17 or 18, compression unit 14 is bearing on the side face 19 of bottom roll 3 of drafter 1 thus.Compression unit 14 comprises the accommodation section 20 of the axle 12 of the roller 4 that is used to pressurize.Compression unit 14 comprises load maintainer 21 in addition, it act on basically cylindrical so bearing- surface 17,18 the middle part and compression unit 14 pressed to bottom roll 3.
The mechanism 15,16 that is used for deflected fibers yarn 2 constructs with the form of tunnel- shaped pressure channel 22,23, and this passage opens wide towards the bearing- surface 17,18 of cylindrical so.When pressurization roller 4 places bottom roll 3 last time fiber strip 2 to penetrate voluntarily in the pressure channel 22,23 through compression unit 14.The side face 19 of bottom roll 3 forms a conveying mechanism, and it is supported and conveying fiber yarn 2 in the zone of the mechanism that is used for deflection 15,16.Especially in compressional zone 8, wherein fiber strip 2 is very thin and responsive, and this conveying effect of the side face 19 of bottom roll 3 is extremely important, so that compressed fiber strip 2 reaches jaw line 9 injury-freely.Fiber strip 2 is being bearing on the side face 19 all the time and is not leaving bottom roll 3 between jaw line 7 and 9.Advantageously tunnel- shaped pressure channel 22 and 23 is constructed with the groove of U-shaped or V-arrangement basically, and it reduces its free cross section on throughput direction A.
When fiber strip left apron to 5,6 o'clock, be used for the main compressional zone guiding fiber strip 2 of the mechanism 15 of deflection at drafter 1.Be used for deflection mechanism 15 preferably include a spigot surface 24, it in view shown in Figure 1, promptly at a center line perpendicular to the bearing-surface 17 of cylindrical so through in the cross section of pressure channel 22, have a raised profile.Protruding spigot surface 24 with fiber strip 2 from apron to 5,6 and jaw line 7 between the shortest imaginary connecting line in deflection come out.Spigot surface 24 through convexity comes out fiber strip 2 deflection from the draw zone plane with the winding of the spigot surface 24 that forms thus the fiber strip of accomplishing drawing-off to be improved.
The load maintainer 21 that is used for compression unit 14 is configured to the compression spring of helical spring 25 forms.Helical spring 25 is furnished with the face 26 that is supported on the axle 12.Compression spring 25 produces a power of compression unit being pressed to bottom roll 3.Compression spring 25 is arranged in the frame part 27 of compression unit 14.Frame part 27 also comprises the accommodation section 20 of the axle of the roller 4 that is used to pressurize.Construct in this wise accommodation section 20, and promptly compression unit 14 remains on the pressurization roller 4 with a little gap.For compression unit 14 when promoting pressurization roller 4 can not split away off, the accommodation section can dispose one and keep folder 28, and it prevents not to be bearing in bottom roll 3 last time accommodation section 20 from axle 20 slippages when the bearing- surface 17,18 of cylindrical so.Frame part 27 is preferably used the plastics manufacturing, keeps folder 28 thereby can make up simply.A slotted recess 29 that is used for compression spring 25 is set in frame part 27.Compression unit 14 is constructed with the force direction of load maintainer 21 basically symmetrically, thereby the power of compression spring 25 is evenly distributed on the bearing- surface 17 and 18 of cylindrical so.
The mechanism 15 and 16 that is used for deflected fibers yarn 2 is arranged in a batten 30 and 31.Batten 30,31 is connected with the frame part 27 of compression unit 14.Batten 30,31 preferably with the ceramic material manufacturing with can be arranged in the compression unit 14 with moving.Each batten 30,31 comprises the bearing- surface 17,18 of a cylindrical so.Through can being arranged on with moving, batten 30,31 makes on the frame part 27 that the bearing- surface 17,18 of cylindrical so also can be with respect to compression unit 14 motions.This advantage that has is, when the bearing- surface 17,18 that compression unit 14 is placed bottom roll 3 last time cylindrical so accurately is adjacent on side face 19.Only need to pay close attention to the bearing-surface 17 of cylindrical so and 18 high precision during fabrication thus.Needn't accurately guarantee the location of the bearing-surface 17 of cylindrical so on compression unit 14, because the bearing-surface 17 of two cylindrical so and 18 is automatically directed being placed to 19 last times of side face with respect to the bearing-surface 18 of cylindrical so. Batten 30 and 31 preferably has bearing pin 32, and they can snap in the frame part 27 through this bearing pin.
The pressurization roller 4 with compression unit 14 on the direction of visual lines of throughput direction A has been shown in Fig. 2.On the axle 12 of pressurization roller 4, can support a valve jacket 33 rotationally.Fixing outer cover 34 of processing by elastomeric material on valve jacket 33.Axle 12 is fixedly mounted in and loads on the support 13 and can also comprise the valve jacket that another does not illustrate when pressurization roller 4 is configured to two the pressurization during roller.Axle 12 all protrudes in valve jacket 33 in both end sides.On every side of valve jacket 33, settle a frame part 27 of compression unit 14.Lath 30 and similarly the back lath 31 remain between two frame parts 27 by means of bearing pin 32.
An intermediate space 35 is set between frame part 27 and valve jacket 33, it make compression unit 14 can pressurization roller 4 axially on move.The mechanism 15 and 16 that is used for deflected fibers yarn 2 can follow a kind of traverse motion (Changierung) of fiber strip 2 thus on the direction of double-head arrow B.Traverse motion B in drafter 1 is favourable, because the life-span of the elastic outer cover 34 of pressurization roller 4 is improved thus.Fiber strip 2 is under the quite high tension in main compressional zone before jaw line 7, and this tension is produced by drafting force.Cling to from the side when it carries out traverse motion B at the fiber strip 2 that extends through pressure channel 22 under the stress effect on the guide wall 151 of the mechanism 15 that is used for deflection and tractive compression unit 14 simultaneously.Compression unit 14 need not be connected with a traverse motion drive unit.
In the modification shown in Fig. 2, accommodation section 20 is bearing on the axle 12 of pressurization roller 4, as the replacement scheme of this modification, in an embodiment who does not illustrate, also can stipulate, is provided with an accommodation section that is used for valve jacket 33.Valve jacket 33 can be selected a little more longways, thereby it protrudes in outer cover 34 with a bigger amount.Accommodation section 20 only need be complementary with the bigger diameter of valve jacket 33.All the other then compression unit 14 can remain unchanged basically.Advantage with compression unit 14 of the accommodation section that is used for valve jacket 33 is, and is outstanding the axle 12 of pressurization roller 4 is needn't be two of valve jacket 33 distolateral.Can use commercial common pressurization roller thus.
A kind of modification of the compression unit 14 with another load maintainer 21 has been shown in Fig. 3.Description to Fig. 1 and 2 did correspondingly is suitable for here, thereby can cancel the description of repetition.Represent with identical Reference numeral with member identical among Fig. 1 and 2.Load maintainer 21 among Fig. 3 is a kind of butterfly springs 36, and it is made up of a kind of metal wire.Butterfly spring 36 is same as compression spring.Butterfly spring 36 also is bearing in the frame part 27 of compression unit 14 and supports with respect to the axle 12 of pressurization roller 4.To be them at the axle of pressurization roller 4 look up the advantage of butterfly spring 36 needs less structure space, thereby frame part 27 can have a less thickness.Also can realize such compression unit 14 thus, it can be under narrow situation, uses under the situation of the drafter that especially is arranged side by side at very little interval.Can stipulate also that in the embodiment that does not illustrate accommodation section 20 surrounds valve jacket 33.In this structure, the advantage of butterfly spring 36 is, it can realize the thrust bigger than helical spring 25 when having the small construction height between valve jacket 33 and the bottom roll 3.
In Fig. 3, express the another kind of modification of load maintainer 21 by a dotted line, promptly magnet 37.Magnet 37 also is a kind ofly to be used for the suitable load maintainer 21 of compression unit 14 and can to substitute compression spring 25 or 36 use.
Additional modification as at the compression unit shown in Fig. 1 to 3 14 can advantageously change compression unit 14 in this wise according to different rim conditions in the embodiment that does not illustrate, promptly batten 30 and 31 and frame part 27 be configured to integrated member.Under unitarily formed structure situation, can stipulate that the bearing- surface 17 and 18 of cylindrical so no longer separates, but in the zone on outer cover 34 next doors, extends.Can have only the bearing-surface of an only cylindrical so to be present on the compression unit thus, it extends to the zone of the mechanism 16 that is used for deflection from the zone of the mechanism 15 that is used for deflection always and has the recess of the roller 4 that is used to pressurize.
