Abstract

The invention relates to an ultra-high drafting system for a spinning frame. The ultra-high drafting system is used for drafting by the aid of four rollers and two short aprons and mainly comprises three drafting zones including a front zone, a middle zone and a rear zone, the traditional linear drafting mode is replaced by a curved drafting mode in the rear zone to achieve an ultra-high drafting purpose, an additional friction force zone is generated, and the diameter of a rear upper roller is larger than that of a rear lower roller, so that fibers are straightened, and drafting can be carried out advantageously. The front drafting zone performs drafting by the aid of the double short aprons, and the double short aprons are adaptable to high-ratio drafting as compared with a combination of a short apron and a long apron. Pressure fluctuation can be reduced owing to an elastic upper pin, so that the yarn quality can be guaranteed. Compared with other technologies, the ultra-high drafting system has the advantages of good yarn quality and high draft ratio.

Description

A kind of super draft device for fine spining machine
Technical field
The present invention relates to a kind of super draft device of fine spining machine, belong to technical field of textile processing.
Background technology
According to traditional drafting theory, drawing-off is the key factor that causes Yarn Unevenness, drafting multiple is larger, the irregularity of yarn is also larger, this is because in drafting process, the motion of floating fiber can not get control, fiber can not have been caused in the same point speed change move apart from deviation, moves apart from deviation to be directly proportional with drafting multiple.So generally adopting in the additional friction force bound pair draw zone floating fiber is controlled.
The approach that improves drafting system total draft multiple has two kinds, and the one, increase draw zone; The 2nd, improve the drawing-off ability of each draw zone.Increase draw zone and can strengthen technology difficulty, therefore the general drawing-off ability of selecting to improve each draw zone.The drafting back zone of traditional drafting system is the drawing-off area in preparation, and its drafting multiple is generally less than 1.4 times, and the drafting multiple that therefore improves the back zone is that super draft is a break-through point.
Summary of the invention
The object of the invention is to overcome existing technical deficiency, provides a kind of spinning quality high, the fine spining machine super draft device that drafting multiple is large.
Purpose of the present invention can realize by following technical measures: this super draft device is four roller double-short leather-ring drawing-offs, tradition four roller draft back zones are the straight line drawing-off, so that back zone drafting multiple is restricted, the present invention changes back zone straight line drawing-off into curve drawing, can produce additional friction force circle, reinforcement does not make again long fiber be obstructed to the control of floating fiber, thereby strengthens the multiple that protracts.On the basis that guarantees its spinning quality, its drafting multiple is also improved accordingly, drafting multiple can reach more than 100 times, has simultaneously good varietal adaptation.
Purpose of the present invention can also realize by following technical measures: the draw zone of this four rollers double short belt drafting device is divided into proparea, middle district and back zone, and wherein proparea, middle district are main draw zone.4 bottom rolls all are driving rollers, and 4 top rollers on it are by frictional drive.In before the drawing-off of bottom roll and middle front upper roller employing double-short leather-ring, to adapt to high drafting.The in-built flexible upper pin of upper leather ring, lower apron is in-built downside pin, and pin adopts K 2Pin presses down pin, and the downside pin updip has been improved the concave phenomenon of cushion rubber.Between middle front roller and middle rear roller, collector is installed, is shunk the width of sliver, reduce scattering and disappearing of flyings and limit fiber.
The present invention is four roller double short belt drafting devices, is four roller double-short leather-ring drawing-offs, comprises roller 1, roller 2, roller 3, roller 4, roller 5, spring top pin 6, downside pin 7, double-short leather-ring 8,9 and collector 10.Spring top pin 6 is contained in the upper leather ring 8, and downside pin is contained in the lower apron 9, and collector 10 is installed between roller 2 and the roller 3.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
By shown in Figure 1, rove enters the first break draft district by the rear feeding rear roller 4,5 that gets off of unwinding on the bobbin cradle, because 4 top roller diameters are greater than four bottom rolls, and is curve drawing, and multiple can reach 6 times of drawing-offs therefore protract in the back zone.Then sliver enters middle draw zone through drawing rollers 3, shrinks the sliver width by collector 10 again.Then sliver enters the front draft zone by roller 2, again realizes high drafting under double-short leather-ring 8,9 drawing-off effect, at last from roller 1 output.

Claims (5)

1. a super draft device that is used for fine spining machine is characterized in that this drafting system is four roller double-short leather-ring drawing-offs, has improved drafting multiple when guaranteeing yarn quality.
2. a kind of super draft device for fine spining machine according to claim 1 is characterized in that drafting back zone adopts curve drawing, so that produce additional friction force circle, improves the control to floating fiber, improves the protract effect of multiple of back zone thereby reach.
3. a kind of super draft device for fine spining machine according to claim 1 is characterized in that using collector 10 between roller 2 and roller 3, shrinks the sliver width, reduces scattering and disappearing of flyings and edge fiber.
4. a kind of super draft device for fine spining machine according to claim 1 is characterized in that its proparea drawing-off is the double-short leather-ring drawing-off, can adapt to powerful drawing-off.
5. a kind of super draft device for fine spining machine according to claim 1 is characterized in that using spring top pin 6, has reduced the fluctuation of nipper pressure, thereby has guaranteed yarn quality.
