Description
Technical field
The present invention relates to a kind of drafting system that is used for a staple fibre yarn of drawing-off, it has a following apron and the upper leather ring that the inboard and the outside are arranged structureless, that driven by bottom roll, here apron also obtained driving thus under upper leather ring can flexibly press, upper leather ring is by at least two guide guiding of settling successively by the fibre transportation direction, and a spring-loading pressing plate is placed between two guides here.
In addition, the present invention relates to be used for the upper leather ring guider of above-mentioned drafting system.
Background technology
The prior art of this class drafting system is to be representative with Deutsche Bundespatent 1112433 and Deutsche Bundespatent 1137362.This drafting system known to everybody, following apron and upper leather ring are the smooth aprons of no any structure.
Therefore upper leather ring always can not guarantee synchronously fully.Be that a kind of pure friction connects between upper leather ring and following apron, have slippage to a certain degree.Because slippage, the speed of upper leather ring is forced to be slower than down slightly the speed of apron.
Different apron speed influence the fiber grasping force, and the fiber control of fiber strip when drawing-off is degenerated.
The pressure distribution that produces on the wide compressive plane between upper leather ring and the following apron by pressing plate can only be improved the control of fiber a little, makes it speed and slows down because upper leather ring has further been braked in the subsidiary friction that produces of the pressure that the pressing plate extruding causes.Therefore the meeting difference is bigger for speed between the apron up and down, makes fibre guide ribbon random and drawing-off inhomogeneous.
In addition, upper leather ring and following apron that non-of a sort day disclosure text 2002-193416 learns, outer surface all has a kind of structure.It is the structure that upper leather ring has the profile of tooth protuberance.Following apron has corresponding recess, makes the tooth of upper leather ring be embedded into recess.Upper leather ring is to connect transmission by a kind of pure form fit like this.Shown in the shortcoming of structure be that upper and lower apron utilizes its tooth portion always must accurately coordinate mutually, so the manufacturing expense costliness.
Summary of the invention
Task of the present invention is to improve the synchronous of upper leather ring and simplify this known devices.
The solution of this task is, upper leather ring has a structurized surface at least on its outside, and its inboard is made up of in the material of the easy slip of guide and pressing plate a kind of the face-off.
The structure that is provided with on the upper leather ring outside encloses friction to hypodermis and connects the combination that is connected with form fit.Usually employed apron down is with a kind of elastic rubber material manufacturing, and it has a smooth and structureless surface.Elasticity by guide and pressing plate loads, and the upper leather ring structure is pressed onto down in the elastomeric material of apron.The protuberance point of upper leather ring structure forms the recess of following apron and reaches a kind of form fit connection of part.Friction connects the combination that is connected with form fit to be played good upper leather ring synchronous effect and significantly reduces slip, even also like this under the pressurization situation of higher pressing plate and guide.Therefore fiber can have a well-proportioned grasping force and obtain Optimal Control during in drawing-off under the very long length.The good synchronization of upper leather ring is to obtain the relative guide of its inboard and the material support that pressing plate easily slides.
The present invention also has this advantage, and promptly the upper leather ring guider can be applied on the known drafting system very simply.So far employed apron down can continue to use, and need not change.
If the structure on the outside extends the whole width of upper leather ring, the manufacturing of upper leather ring is just simple especially.If upper leather ring is a woven belt, then obtain a kind of good especially structure.Upper leather ring is made up of a kind of film with patterned structure, and is also good as woven belt.
If be not made up of a kind of rubber elastic material in the inboard, upper leather ring just can good especially sliding on guide and pressing plate.Here preferably a kind of material harder and that easily slide is such as polyamide.
Technical scheme of the present invention is that pressing plate contains at least one guide.By second guide of fibre transportation direction for example is that trailing edge by pressing plate constitutes.Can reduce the number of components of use like this and make designs simplification.By selecting a kind of material of easy slip, in addition usually as the top roller of rotation by first guide of fibre transportation direction as a fixed guide.The structure of upper leather ring guider if do not contain the top roller of rotation, just can be simplified greatly.Can be provided with like this, by first guide of fibre transportation direction and pressing plate is combined into one and be made of the leading edge of pressing plate.
Another technical scheme of the present invention is that the turning radius of second guide is less than the turning radius of the trailing edge of following apron.Second guide can the right skewer mouth line of more close delivery roller.Fibre guide during drawing-off can further improve by the upper leather ring guider of lengthening.
Other advantages of the present invention and feature can be learnt from two following embodiment.
Description of drawings
The zoomed-in view that Fig. 1 dissects for the part in the upper leather ring guider zone of drafting system; Fig. 2 is the view of upper leather ring guider of the another kind design of similar Fig. 1.
The specific embodiment
Upper leather ring guider 1 illustrated in figures 1 and 2 is, such as the part of the drafting system of only partly representing 2 that is used for ring throstle.2 of this drafting systems mainly showed the apron formed by down apron 3 and upper leather ring 4 to 3,4 and subsequently delivery roller to 5,6.Staple fibre yarn 7 of answering drawing-off enters apron to 3,4 and leave delivery roller to 5,6 according to direction of arrow B by fibre transportation direction A.For purposes of the invention, whether apron 3,4 the place aheads are provided with other drafting system 2 roller to or at delivery roller 5,6 the place aheads are provided with more roller to all inessential.Owing to press known mode own around a bottom roll 8 and by a following apron cradle 9 with the following apron 3 that a kind of smooth leather or elastomeric material are formed.For making down apron 3 tensionings, a tension rail 10 can be set, such as an elasticity loaded roll form.Roller 5 and 8 be along machine vertically by the bottom roll of transmission, and roller 6 is pressure rollers, each spinning spindle position all has a this pressure roller.Following apron cradle 9 has a trailing edge 11 at itself and roller to 5,6 these sides that stand facing each other, and removes apron 3 with this place and guides downwards from the drawing-off plane by a turning radius.Pressure roller 6 constitutes output jaw line 12 with bottom roll 5.
According to Fig. 1, with the drafting system 2 of a upper leather ring guider 1 two guides 13 and 14 and pressing plates 15 are arranged, the latter by upper leather ring 4 around.First guide 13 by fibre transportation direction A is top rollers 16 of rotation, and it is bearing on the fixing axle 17.Second guide 14 by fibre transportation direction A is to be connected with axle 17 by a matrix 18.Axle 17 and matrix 18 are to press downward apron by mode shown in the power arrow F by known devices.Pressing plate 15 is placed between guide 13 and 14, can be subjected to being supported on the load of the spring 19 on the matrix 18.
Preferably by this sample loading mode design, the upper leather ring that promptly is between leading edge 22 and the trailing edge 23 passes through a plane domain 24 to pressing plate 15, and the pressure of spring 19 large tracts of land in this zone is distributed on the upper leather ring 4.Plane domain 24 is selected greatly as far as possible, and the fiber that enters into like this between upper leather ring and the following apron obtains Optimal Control owing to being subjected to uniform pressure.Plane domain 24 must not be flat, and this zone also can be matched with down the bending of apron cradle 9.
Fig. 2 represents the modification according to upper leather ring guider 1 of the present invention.Identical parts all use identical Reference numeral, therefore do not need to illustrate once more.Here second guide 14 ' by fibre transportation direction A is not a separate part, but is combined into an integral body with pressing plate 151.Guide 14 ' is to be made of trailing edge 23 '.The plane domain 24 ' of pressing plate 15 ' is much bigger in the case.This point further improves fiber control.The elastic deflection load by force arrows F1 of pressing plate 15 ' represents.
In addition, the turning radius on the trailing edge 11 of turning radius apron cradle 9 under being significantly less than on the trailing edge 23 ' that constitutes guide 14 '.Trailing edge 23 ' can obviously more close output jaw line 12 like this, and fiber does not experience the distance that upper leather ring and following apron lead and shortens to Min..Especially a guide 14 ' that outwards protrudes very approaching output jaw line 12 can use a very thin upper leather ring 4 to reach, such as a kind of woven belt.Upper leather ring 4 is thinner, and then the turning radius on the guide 14 ' is just little, thereby guide 14 ' is more closely near output top roller 6.
Be held (not illustrating) again according to first guide 13 ' by the fibre transportation direction among Fig. 2, and shown in power arrow F2, compress.Guide 13 ' also can be made of a upper leather ring by similar Fig. 1 under illustrated case like that.It is preferred to use particularly that yes under the situation of woven belt as upper leather ring 4, even guide 14 ' is set to fixed part 25.So just can dispense the top roller that complicated tape spool holds.
If pressing plate 15 ' prolongs against fibre transportation direction A, then can further reduce number of components, and the leading edge 22 ' of pressing plate 15 ' is born the function of guide 13 '.Have only the inside that is positioned at upper leather ring 4 as the pressing plate 15 ' of single whole bonded block, guide 13 ' is the leading edge 22 ' formation by pressing plate 15 ' here, and guide 14 ' is the trailing edge 23 ' formation by pressing plate 15 '.Because the length that reaches its maximum possible between leading edge 22 ' and the plane domain between the trailing edge 23 ' 24 ' of pressing plate 15 ', thereby can carry out best fiber and control.
