Description
Technical field
The present invention relates to spinninging technical field, more particularly to a kind of spinning for strengthening the control of draw zone fiber
Device and Yarn spinning method.
Background technology
RING SPINNING technology is a kind of widest spinning technique of current domestic and international application, but the technology is due to twisting three
The presence of angular region and increased the yield of filoplume.Therefore, for the improvement one of ring spinning technology especially its twisting process
Directly the spinning more popular problem of research, and achieve in terms of engineering practice with theoretical research a series of plentiful and substantial researchs into
Really, such as compact spinning, solo spun, dislocation spinning etc..Especially compact spinning technology, it before ring throstle draw-gear by increasing
Plus a fiber aggregate area so that fiber realizes twisting in the state of parallel, tight, is the important of ring spinning technical field
Reform.Because fiber is more uniformly stressed during resultant yarn, obvolvent is tight, thus yarn texture and quality have the mutation of matter,
Use scale at home also gradually expands, especially nearly 5 years, from 2008 less than 1,000,000 ingots, more than 500 ten thousand ingots in 2010,
To increase at faster speed more than 25,000,000 ingots, and future by 2014.Mainly there are five kinds of different knots in the world at present
The compact spinning system of structure, wherein four producers gather for negative-pressure air-flow.Therefore, it is current Advance of Compact Spinning Technology that suction type gathers
In be most widely used gather form, it makes the fiber strip cross-direction shrinkage after drawing-off using negative-pressure air-flow, gather and closely,
And then the fiber at yarn edge is effectively gathered to Sha Gan centers, twist triangle zone is reduced to greatest extent, so as to significantly
Yarn filoplume is reduced, fiber utilization coefficient and yarn strength is improved.But negative pressure collecting needs to increase extra energy consumption, so as to increase
Plus production cost.
For the problems referred to above, the present invention provides a kind of spinning apparatus and Yarn spinning method for strengthening the control of draw zone fiber,

Set is close to front rubber roll set, and the 3rd set, the 4th set, the 5th set, the 6th set of the second Final finishing component is close to back cot set, electricity
Machine directly drives front roller axle to rotate, and drives front roller set to rotate then, drive then the 7th set of tight face contact therewith,
8th set and front rubber roll set rotate, the 7th set, the 8th set of rotation drive the 3rd jackshaft of connection fixed thereto to rotate then, it is front
Rubber roll set rotates the first set and second set of rotation for driving left front clearing up assembly and right prefinishing component then, and first is driven then
Jackshaft is rotated, and front roller axle is rotated and drives middle roller axle to rotate by first gear then, drives middle roller set to rotate then,
Then drive mid-rubber roll intimate contact therewith to cover to rotate, middle roller axle is rotated and drives rear roller axle to turn by second gear then
It is dynamic, drive rear roller set to rotate then, drive back cot intimate contact therewith to cover then and rotate, back cot set rotates band then
The 3rd set, the 4th set, the 5th set, the 6th set of dynamic second Final finishing component is rotated, and the of the first Final finishing component is driven then
Three sets, the 4th set, the 5th set, the 6th set of rotation, drive respectively the of the first Final finishing component and the second Final finishing component then
Two jackshafts are rotated；During spinning, rove covers the pressing feeding and rear roller set between by back cot, and the is entered after being exported by rear jaw
In the middle of the second jackshaft or between the 5th set and the 6th set second between the 3rd set of two Final finishing components and the 4th set
Axle, now the CONTACT WITH FRICTION in the second jackshaft and rove between fiber provide the first additional friction field of force for fiber, the 3rd set
And the 4th set or the 5th set and the 6th set more obvolvent caused between fiber, then into the 3rd set of the first Final finishing component
And the second jackshaft between the second jackshaft between the 4th set or the 5th set and the 6th set, now the second jackshaft with it is thick
CONTACT WITH FRICTION in yarn between fiber provides the second additional friction field of force, the 3rd set and the 4th set or the 5th set and the 6th for fiber
Set causes the more obvolvent between fiber, pressing output between the upper leather ring for then being covered by mid-rubber roll and middle roller set, after being subject to
The drawing-off effect in the first break draft area of drawing rollers pair and middle drawing rollers to constituting, enters left front arrangement group after being exported by middle jaw
The first jackshaft between the first set of part or right prefinishing component and second set, now the first jackshaft and fiber in rove it
Between CONTACT WITH FRICTION provide the 3rd additional friction field of force for fiber, first set and second set of more obvolvent caused between fiber,
It is last that the pressing output and front roller set between is covered by front rubber roll, by middle drawing rollers pair and front traction roller to leading before composition
Stretch the drawing-off effect in area, obtain the yarn after drawing-off, yarn by after the output of front jaw by the 3rd between the 7th set, the 8th set
The top of countershaft passes through, and is on the one hand gathered effect by the mechanical of front Nesting Zone, on the other hand turning by the 3rd jackshaft
It is dynamic to drive output, so as to reduce resistance twist effect.
