Abstract
The invention relates to an isolated siro spinning device which is arranged on a ring spinning frame, belonging to the textile industry, wherein, a drafting mechanism comprises three pairs (front, middle and back) of rubber rolls and rollers; the front rubber rolls comprise a drafting rubber roll, an isolation rubber roll and a pressure stand which is arranged on the mandrels of the two rubber rolls; two grooves are arranged on the isolation rubber rolls for fibre band to pass through; when the cradle of the ring spinning frame pressures, a gripper of a spring pressure device holds a minor axis of the pressure stand and exerts pressure on the pressure stand to stick the drafting rubber rolls and isolation rubber rolls to the surface of the front roller. The invention has the advantages of small space between the two rovings which are fed into the device to avoid the defects of spinning tension difference of the two rovings and frequent broken ends, automatic piecing, obedient stick to filoplume when the fibre band rotates in the groove, obvious resultant plied yarn effect and better quality.
Description
Technical field
A kind of isolated siro spinning device that the present invention relates to install additional on ring throstle in the caused by spinning industrial production is in order to spin the single thread of similar strand style.
Background technology
Match network spinning technique is a kind of spinning method of Australian wool industrial research institute and International Wool Secretariat common research and development on the drafter basis of common ring spindle yarn, its spinning principle is in the drafter that the common ring spindle spinning frame is made up of back cot rear roller, middle rubber roll middle roller and three pairs of elements of preceding rubber roll front roller, feed simultaneously two parallel and keep the rove of a determining deviation, two strands of rove yarns converge at the jaw place that preceding rubber roll front roller is formed after drawing-off, and twist on twist becomes doubled yarn, spun yarn, doubling, three operations of twisting thread once merged finish.
The match network spins in the spinning process, and two sub-thread slivers have had a spot of twist before converging plying, and the filoplume on the sub-thread sliver of plying back significantly reduces, and sliver is laterally pushed again in the strand simultaneously, has stoped filoplume slippage in the yarn body.
The match network spins in order to obtain the yarn texture of strand effect, must possess following condition: the single thread before the plying must be by a certain amount of number of twists, i.e. self winding number.Therefore, between two rove of feeding bigger spacing should be arranged, so just strengthen the width of twist triangle zone.Under identical spinning tension condition, the suffered spinning tension of single sliver increases with the increase of twist triangle zone, and the probability of broken end improves.
Summary of the invention
For overcoming between two rove that above-mentioned match network spins feeding bigger spacing is arranged, the big thereby high shortcoming of broken end probability of big, the single sliver spinning tension of twist triangle zone width the invention provides a kind of isolated siro spinning device.
The technical measures that the present invention takes are as follows: described isolated siro spinning device comprises the drafter that traditional ring throstle is made up of back cot rear roller, middle rubber roll middle roller, three pairs of elements of preceding rubber roll front roller, is characterized in: before described the rubber roll element by drafting rubber roller, isolate rubber roll and be installed in described drafting rubber roller and the pressure foot of isolating on the mandrel of rubber roll is formed; The cushion rubber of described isolation rubber roll is provided with two grooves that two coring bars pass through, the centre-to-centre spacing 1.5～2mm between recess width 0.8～1.2mm, two grooves; Described pressure foot is a metallic article, and its underpart is provided with the deep-slotted chip breaker that matches with the circular arc of drafting rubber roller and insulation rubber roller core shaft; The pressure foot middle part is provided with a minor axis, and during the pressurization of ring throstle reel cage, described minor axis is gripped by the pawl of holding of cradle spring pressing mechanism, and pressure foot is exerted pressure, and makes the traction rubber roll simultaneously and isolate rubber roll to be fitted in the front roller surface.
Beneficial effect of the present invention is:
The spacing of two strands of rove yarns of feeding is minimum, the spinning tension difference of two strands of single thread bars and the shortcoming that easily breaks end have been avoided, filoplume can be attached on the sliver when sliver turned round in isolating the rubber roll groove, the strand effect of institute's yarn is more obvious, yarn quality is higher, in case single thread broken end, but automatic joint.

The specific embodiment
The present invention improves on the basis of existing ring throstle siro spinning device, only substitutes former front leather roller with this isolated siro spinning device, and does not change other original parts of ring throstle.
It is to form like this that two grooves that two coring bars pass through are set on the described isolation rubber roll cushion rubber: be inserted in earlier a quoit on the cartridge housing of rubber roll, be inserted in two cushion rubbers respectively in the both sides of quoit, and make the inner side edge of cushion rubber and quoit side separate a spacing, to form groove; The height of quoit is consistent with two cushion rubber height that are inserted in.
In the spinning process, two parallel feeding drafters of rove that spacing is very little enter respectively in the groove of isolating on the rubber roll, and the sub-thread sliver turns round in groove, and filoplume laterally is squeezed in the yarn body.Because the spacing of two rove is very little, spinning tension is basic identical, is difficult for the single thread broken end, even the single thread broken end also can automatic joint, the strand effect is obvious, and the common match network of mass ratio spun yarn is better.
