Description of drawings
Fig. 1 is the side view of analysing and observe with part of an amplification of a drafter with compression unit,
Fig. 2 is the view along the compression unit of arrow II direction among Fig. 1,
Fig. 3 is the view that is similar to Fig. 1 of a modification of compression unit.
The specific embodiment
Just the drafter 1 shown in the part is made 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 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 finishing drawing-off is then by 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.
Construct with the form of tunnel- shaped pressure channel 22,23 accommodation section 20,16 that is used for the mechanism of deflected fibers yarn 2, and this passage opens wide towards the bearing- surface 17,18 of cylindrical so.Fiber strip 2 can penetrate in the pressure channel 22,23 voluntarily when pressurization roller 4 places on the bottom roll 3 by 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 accommodation section 20,16 of the mechanism that is used for deflection.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, the accommodation section 20 of mechanism that is used for deflection is at the main compressional zone guiding fiber strip 2 of drafter 1.The accommodation section 20 that is used for the mechanism of deflection preferably includes a spigot surface 24, and it promptly passes through to have a raised profile in the cross section of pressure channel 22 at a center line perpendicular to the bearing-surface 17 of cylindrical so in view shown in Figure 1.The projection 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 by projection 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 finishing 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 a retaining clip 28, and it prevents that accommodation section 20 is from axle 20 slippages when the bearing- surface 17,18 of cylindrical so is not bearing on the bottom roll 3.Frame part 27 is preferably used the plastics manufacturing, thereby can make up retaining clip 28 simply.A slotted recess 29 that is used for compression spring 25 is set in frame part 27.Compression unit 14 is constructed symmetrically with the force direction of load maintainer 21 basically, 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 ceramic material manufacturing and can being arranged in the compression unit 14 with moving.Each batten 30,31 comprises the bearing- surface 17,18 of a cylindrical so.By 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 that the bearing- surface 17,18 of cylindrical so accurately is adjacent on side face 19 when placing compression unit 14 on the bottom roll 3.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 on being placed to side face 19 time 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 by this bearing pin.
Figure 2 illustrates the pressurization roller 4 on the direction of visual lines of throughput direction A with compression unit 14.On the axle 12 of pressurization roller 4, can support a valve jacket 33 rotationally.On valve jacket 33, fix an outer cover 34 of making by elastomeric material.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 lath 31 in the back 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.Before the jaw line 7 in main compressional zone fiber strip 2 be under the quite high tension, this tension is produced by drafting force.When it carries out traverse motion B, cling on the guide wall 151 of the mechanism 15 that is used for deflection from the side at the fiber strip 2 that extends by pressure channel 22 under the stress effect and tractive compression unit 14 simultaneously.Compression unit 14 does not need to 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, also can stipulate in an embodiment who does not illustrate, and 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 needs to 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.
Figure 3 illustrates a kind of modification of compression unit 14 with another load maintainer 21.Correspondingly be suitable for herein at the description that Fig. 1 and 2 did, 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 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, especially uses under the situation of the drafter that 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.
Express the another kind of modification of load maintainer 21 in Fig. 3 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 extends in the zone on outer cover 34 next doors.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.
