Description
Technical field
The present invention relates to engineering goods---the compact spinning apparatus of ring throstle used in a kind of textile industry.
Background technology
Traditional ring throstle comes with some shortcomings on spinning mechanism, promptly through the fibre bundle of drawing-off with certain width and after leaving front roller under the free state, just be processed to yarn immediately, just formed spinning triangular zone in the formation zone of yarn this moment, because the spinning triangular zone loose fibres can not be controlled well, many fibers of fibre bundle periphery can be scattered in advance or can not be controlled fully, cause many fibers can not be twisted with the fingers in the yarn and stretch out yarn and form " filoplume " outward.Simultaneously since in twisting process the heterotonia of each fiber in the spinning triangular zone, cause resultant yarn when bearing pulling force, the brute force of yarn is lower than the summation of each root fiber bearing capacity on the yarn cross section.In sum, the yarn quality of traditional ring throstle all exists very big deficiency as indexs such as filoplume, brute force, bar evenness and fiber losses.For traditional ring spinning technology is significantly improved on yarn quality, just must improve the conveying form of fiber before the twisting, i.e. twisting reduces or eliminates twist triangle zone before being shaped, make fiber parallel, stretch and as far as possible closely arrange mutually.For this reason, the method that adopts is to install collector in drafting unit additional usually, resultant yarn filoplume is improved, but the resultant yarn bar evenness has been subjected to bad influence.
Summary of the invention
The objective of the invention is provides a kind of compact spinning apparatus that fiber can be strained, stretched and gathers in the course of conveying of fibre bundle before the twisting resultant yarn that makes for ring throstle, by changing the preceding form of fibre bundle in course of conveying of twisting shaping, indexs such as filoplume, brute force, bar evenness and fiber loss are had clear improvement, thereby make yarn quality obtain basic raising.
The compact spinning apparatus of the ring throstle that the present invention proposes, comprise that existing drawing rollers are right, roller stand, the reel cage pressue device, it is characterized in that being provided with two ends and be fixed on air intake duct on adjacent two roller stands with some inlet scoops and exhaust outlet, it is outer and have a cohesion cover of collection surface on the circumferencial direction corresponding to the position, inlet scoop to be enclosed within air intake duct, be stuck in the tensioning apparatus in the cohesion cover chute, be enclosed within the ventilative conveying circle on cohesion cover and the tensioning apparatus, and the ventilative transmission pressue device of carrying circle, described transmission pressue device is installed on the reel cage body fore paw, it comprises the pressurization roller of front roller, the ventilative pressurization roller of circle and the driving member between described two rollers carried, under the reel cage pressurized state, the ventilative pressurization roller of circle of carrying is pressed on the ventilative conveying circle surface that is held up by the cohesion cover.The ring throstle compact spinning apparatus of Gou Chenging can make the fibre bundle of front roller output under the effect of the negative pressure that exhausting system produced thus, be adsorbed on the above-mentioned ventilative conveying circle, and pressurization transmission device and ventilative the conveying under the acting in conjunction of enclosing, the state output draw zone of fibre bundle to be tightened up, to stretch and to gather mutually, realize reducing or eliminating spinning triangular zone before the twisting resultant yarn, obviously improve the purpose of yarn quality.
Compare with traditional spinning technique, on drafting unit, increase the tight spinning apparatus of a cover, the conveying form of fibre bundle before twisting is greatly improved, not only make resultant yarn have powerful high, filoplume is few, bar evenness good and yarn defect premium properties such as less, and can obtain considerable economic and obviously improve production environment.
