Description

A kind of production hanged down the spinning machine of turning round yarn

Technical field

The invention belongs to fiber yarn spinning field, particularly a kind of spinning apparatus of low torsion loop ingot yarn makes this yarn keep stable low moment of torsion.

Background technology

Existing twisting is the important step of short staple spinning.Yarn will produce the abundant residues moment of torsion during the twisting, and then the quality of subsequent product is had very big influence.For example in knitted fabric, because the variation of yarn internal torsion stress, the coil of fabric will rotate and discharge inner torsional stress, and it perk is as a result also given prominence to fabric face, and other one then is trapped in fabric.This distortion of coil will increase the spirality of fabric, and produce the distortion of the similar rib effect that a kind of utmost point need avoid.

The method that reduces the yarn residual torque at present mainly contains two kinds: eternal law and physics method.Eternal law is mainly with the elastic torsion of yarn distortion changing into plastic deformation, thereby discharges residual torque.It relates generally to material hot treatment, chemical treatment and adds wet process etc., but for natural fiber, eternal law may cause the damage and the destruction of fiber.

Physical laws is a kind of pure mechanical technique, and it makes full use of the internal structure of yarn, makes the mutual balance of residual torque that different fibers produce still to keep elastically-deformable feature.

People attempted the concrete grammar and the device of many reduction residual torques for this reason, but did not also obtain comparatively desirable device always.

The spinning apparatus of existing ring spun yarn line is seen Fig. 1, it comprise delivery roller to 1, comprise the twisting and the coiler device of the yarn of twizzle 4, the twisting of yarn and coiler device generally comprise spool 6, rings 7, steel traveler 8.Twizzle 4 is provided with to reduce yarn tension for pressed yarn thread balloon 9 height, and the angle a of its original state is bigger.Along with spinning is constantly carried out, rings 7, steel traveler 8 and twizzle 4 all can rise and descend, thereby influence its angle a, see Fig. 2.

For obtaining the ring spun yarn line of low moment of torsion, need to improve existing ring spinning method and spinning apparatus, this has been appearred in many researchs, attempt to achieve the goal with the method for traditional reduction yarn residual torque, the process and apparatus that does not have torsion loop ingot yarn as the disclosed sub-thread of Chinese patent literature CN1453401A, it has proposed to obtain not having by the physical method of above-mentioned reduction yarn residual torque the yarn of moment of torsion on traditional ring spinning yarn machine, on the structure improvements mainly be the delivery roller of existing ring spinning apparatus to and twizzle between yarn sliver-splitting device 5 and false-twisting device 2 are set, see Fig. 3, Fig. 4 and Fig. 5, but yarn sliver-splitting device and false-twisting device structure that it provides are very complicated, and inconvenience is made and used; Especially the groove of yarn sliver-splitting device rotatablely moves and can carry out cutting movement repeatedly to the yarn trigonum, makes the brute force of yarn decline to a great extent; Set in addition false-twisting device also need with ring rail move up and down and servo-actuated, this not only makes whole spinning apparatus very complicated, and yarn also can not get stable false twisting effect, and spinning effect is relatively poor, the cost height, incompatible actual demand of transforming the ring spinner of existing suitability for industrialized production.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of suitability for industrialized production, false-twisting device of adapting to can keep stablize the spinning machine of the low torsion loop ingot yarn of production of false twisting effect to yarn at the deficiency of above-mentioned ring spun yarn wire processing device, and can be applied to easily have now in the transformation of ring spinning apparatus.

The present invention solves the problems of the technologies described above the technical scheme that is adopted:

A kind of production hanged down the spinning machine of turning round yarn, comprise a ring spinner and false-twisting device, the delivery roller that false-twisting device places ring-spinning machine to and twizzle between, delivery roller is to two rove of preceding feeding, it is characterized in that: two rove are a synthetic one thread before delivery roller is to laggard false-twisting device, false-twisting device place twizzle directly over and maintain static.

Above-mentioned false-twisting device can be fixed on the frame or be fixed on the roller pier of spinning machine, even also can be fixed on the other fixture of spinning machine, makes not moving up and down with ring rail or twizzle of false-twisting device.

Above-mentioned false-twisting device can be used existing false-twisting device, as pneumatic false-twisting device and mechanical false-twisting device, the ratio that keeps a reverse speed of determining between the yarn machine spindle of false-twisting device and ring spinner, false-twisting device makes the yarn that processes have controlled residual torque in order to the arrangement architecture and the stress distribution of control and adjusting yarn internal fiber bundle.

Prior art is also adopted in the driving of above-mentioned twizzle, twizzle is provided with to reduce yarn tension for pressed yarn thread balloon height, twizzle adopts the lifting of change journey, promptly begins to spin from cop, and the lifting traverse of twizzle and the level amount of liter increase to normal value gradually.

For guaranteeing best spinning quality, above-mentioned false-twisting device is arranged on the top near the limes superiors position of twizzle vertical motion.

For guaranteeing best spinning quality, passed the endoporus of twizzle by the central vertical of the yarn of false twisting through false-twisting device.

Compared with prior art, the invention has the advantages that:

1, by delivery roller to two rove of preceding feeding, two rove synthetic one thread before delivery roller is to laggard false-twisting device, yarn after false twisting can more effectively be eliminated the moment of torsion of yarn than existing spinning machine, can obtain the low yarn of yarn residual torque.

2, false-twisting device is arranged on twizzle directly over just can make full use of existing spinning apparatus and reach the effect of false twisting, therefore whole spinning apparatus is simple in structure, and can be convenient, rebuilding at low cost has ring spinner now.

3, by false-twisting device being arranged on top near the limes superiors position of twizzle vertical motion.Can play better false twisting effect, the yarn residual torque that obtains is low, and therefore the yarn qualities that makes is good.

The specific embodiment

Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.

As Fig. 6, Fig. 7, shown in Figure 8, a kind of spinning machine of producing low moment of torsion yarn, it comprises existing ring spinner (referring to Fig. 1 and Fig. 2) and false-twisting device 2, the delivery roller that false-twisting device 2 places ring-spinning machine to 1 and twizzle 4 between.

Two rove 31 enter delivery roller and enter false-twisting device 2 preceding synthetic one yarns 3 after 1.

Yarn 3 formed fixing angle b with false-twisting device 2 when yarn 3 entered false-twisting device 2.

Above-mentioned false-twisting device 2 must maintain static, and it both can be fixed on the frame 12 of ring spinner, or is fixed to other places of loom, also can be fixed on the correct position of spinning machine periphery.

The twisting of the yarn of above-mentioned ring spinner is identical with existing spinning machine with coiler device, comprises spool 6, rings 7, steel traveler 8 etc., no longer is described in detail at this.

In spinning process, along with the spinning process, twizzle 4 need move up and down, but angle b is constant all the time, sees Fig. 7 and Fig. 8, so false-twisting device really played the effect of false twisting, has reached the effect of false twisting, and the yarn that makes just can reduce residual torque.
