Abstract
The utility model discloses a compact spinning core yarn covering device capable of feeding three rough yarns by drafting of four rollers. The device comprises a rear drafting roller pair formed by a rear roller and a rear leather roller, a middle-rear drafting roller pair formed by a middle-rear roller and a middle-rear leather roller, a middle-front drafting roller pair formed by a middle-front roller and a middle-front leather roller, and a front drafting roller pair formed by a front-lower roller, a front leather roller and an anti-twisting leather roller, wherein the front-lower roller is a narrow-slot-type hollow steel roller with the diameter of 50mm; an air suction assembly is arranged in the front-lower roller; an airflow guiding plate device is additionally mounted above the front-lower roller. In order to improve the core covering effect, the three rough yarns are fed to the device from a three-horn-mouth feeding device and the rear drafting roller pair at the same time, the three rough yarns can be in the same color or different colors. Based on a three-rough-yarn-feeding mode, core threads at the front roller can be easily positioned in the middle of fiber distribution when being confluent with the fed rough yarns, so that the core covering effect is improved. The device has the effect of a compact spinning technology while realizing the super-high drafting effect. As a result, the yarn forming quality is improved effectively.
Description
Technical field
The utility model relates to the spinning new technical field, and specifically a kind of four roller drafts, three rove feed tight core-spun yarn device.
Background technology
Drafting system is the important component part of fine spining machine work, and its performance directly has influence on yarn quality.General fine spining machine all adopts three roller draft forms at present, comprising the two apron structures of three common rollers and three rollers, the four apron structures that can realize 80～100 times of high drafts.The two apron structures of three common rollers are divided into two draw zones: front draft zone and first break draft district, and the back zone is owing to only adopt simple roller draft, make the middle part friction field a little less than, drafting multiple is generally less than 1.4 times, this is unfavorable to the total drafting multiple that improves fine spining machine, thereby its total draft multiple is between 20～50.In order to solve the low problem of back area draft ability, at Chinese patent " device that involves that is used for high-count worsted machine " (number: 96107383) with " fine spining machine four tape drawing mechanisms " (number: 012439010) disclose a kind of three roller three-aprons and three rollers, four tape drawing mechanisms respectively, preferably resolve the weak problem of back area draft ability of three roller form drafters, make the total draft multiple can bring up to 100.But, because it adopts three roller forms, also namely have only two draw zones, thereby can not realize super draft.At this, at Chinese patent " fine spining machine four apron high draft devices " (number: disclose a kind of four apron high draft mechanisms for fine spining machine 200520073617.2), the total draft multiple is brought up to 150.
Closely spinning is a kind of novel spinning technology of spinning at improved ring throstle, and it is by increasing a fibre deposition district to improve yarn quality before the ring throstle draw-gear.But present tight spinning system can't be realized super draft.Cladded yarn be with powerful and elastic force all preferably synthetic fiber filament be the core silk, staple fibres such as outsourcing cotton, hair, viscose are twisted and the yarn that is spun into together, it has the premium properties of long filament heart yarn and outsourcing staple fibre concurrently.Adopt match network spinning technique coated yarn spinning to obtain a series of progress at present, but mainly be to realize the traditional fine spining machine that has three rollers transformation.At this, the utility model provides a kind of four roller drafts, three rove and feeds tight core-spun yarn device.This device adopts four row roller drafting mechanisms to realize super draft on the one hand, and gathering before the twisting of the hollow roller realization of a kind of major diameter narrow slot type negative pressure of cooperation employing simultaneously fiber improves yarn quality; Adopt the feeding of three rove on the other hand, effectively improve bag core effect.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of four roller drafts, three rove that can effectively improve bag core quality and feeds tight core-spun yarn device.
In order to address the above problem, the technical scheme that the utility model is taked is that ring throstle adopts four roller drafting mechanisms, comprise that the first break draft roller of being made up of rear roller and back roller is right, right by the middle first break draft roller that middle rear roller and middle back roller are formed, right by the middle front draft roller that middle front roller and middle front leather roller are formed, right by the front draft roller of preceding bottom roll and front leather roller, resistance twist roller.
In technique scheme, preceding bottom roll is that diameter is the hollow roller of steel narrow slot type of 50mm, the air draught assembly is contained in its inside, jaw before preceding bottom roll and front leather roller are formed, form the resistance twist jaw with the resistance twist roller, be the fiber aggregate district between preceding jaw and the resistance twist jaw, but the gas-flow deflector device of reinforcing fibre cohesion is housed between preceding jaw and the resistance twist jaw.
After adopting said structure, can be with two draw zones of original three laura structures: front draft zone and first break draft district, rise to three present draw zones: front draft zone, middle draw zone and first break draft district, thus effectively improving drafting multiple, the total draft multiple can be brought up to more than 250 times.
In technique scheme, be to improve bag core effect, adopt three rove by three horn mouth feeding units simultaneously from the rear roller drawing-off to feeding, three kinds of rove that rove can be same color wherein, the also rove of different colours.Adopt three rove feedings, the easier fiber distribution mid portion that is in when the core silk is converged with the feeding rove at the front roller place improves bag core effect.
Description of drawings
Fig. 1 is that the utility model four roller drafts three rove feed tight core-spun yarn device structural representation.
