Description

A kind of double drawing-off Siro-spinning devices and Yarn spinning method
Technical field
The present invention relates to ring spinning new technical field, particularly relate to a kind of double drawing-off Siro-spinning devices and Yarn spinning method.
Background technique
With the continuous advance in epoch, requirement of the people for garment material is continuously improved, and textile clothing industry is at present One follow the fashion, the epoch of diversification and high-quality.Therefore, the development of textile raw material, textile technology also proposed new It is required that.Among these, textile high-quality, high performance and its production and processing cleans the master for having become Modern Textile Industry Developing direction is wanted, and improves the effective way of product specification and added value.With the raising and work of modern life level The quickening of rhythm, the high conformality and easy care performance of textile have become the important attribute of high quality fabric and clothes and significantly mark Will.But there is also many problems, such as cotton fabric dress easily to play fold, washing in terms of conformality for difference Fiber Materials fabric at present Drying rear poor flatness needs ironing, and wool fabric is machine-washed, and easy felting, fabric rivel conformality are poor, and it is conformal that chemical & blended fabric wears easy arch camber Deng.Conformality is inadequate, conformal effect is unstable, existing conformal technique environmental protection index many realistic problems such as not up to standard difficult to control As the serious obstruction of textile high-quality, demand of the modern society people to high-quality dressing has not been adapted to.Research and development are high Conformal textile key technology of preparing simultaneously realizes that its industrial application is to promote China's textile quality and competitiveness in the international market Important channel and industry common recognition.Composite yarn is the yarn that a kind of mutually compound and production structure is carried out using different fibers Line can realize the control of yarn texture and performance in spinning by the control to fiber compound structure, thus needed for realizing The production of yarn.
In view of this, the present invention provides a kind of double drawing-off Siro-spinning devices and Yarn spinning method, drafting system uses three rollers Drawing-off structure, is provided with left roller set and right roller set on the roller shaft of each bottom roll, on the rubber roller of corresponding each upper glue roller It is provided with left rubber roller set and right rubber roller set, and phase is cooperated by the variation of the left roller of each bottom roll set and the diameter of right roller set The variation of the corresponding diameter of the left rubber roller set and right rubber roller set for each upper glue roller answered is realized to the left roller set by rear bottom roll It is led with different in the draft area under roller shaft synchronous drive of right roller the first rove for feeding respectively of set and the second rove Journey is extended through, to realize that the roller shaft in each bottom roll unifies double drafting process of each spindle position under synchronous drive, thus root According to the characteristic requirements of the Siro Yarn of the property and required spinning of the first rove and the second rove fed, specific spinner is realized The optimization design of skill then realizes the production of various different composite yarns.
Summary of the invention
The purpose of the present invention provides a kind of double drawing-off Siro-spinning devices and Yarn spinning method, passes through the roller in each bottom roll The left and right roller set of diameter change is set on axis, realizes and unifies each spindle position under synchronous drive in the roller shaft of each bottom roll Double drafting process, thus according to the characteristic of the property of the first rove and the second rove fed and the Siro Yarn of required spinning It is required that realizing the optimization design of specific spinning process, the production of various different composite yarns is then realized.
In order to achieve the above object, the present invention relates to a kind of double drawing-off Siro-spinning devices, including drafting system, drawing-off systems System include after drawing roller to, middle drawing rollers to, front traction roller pair, first break draft roller is to including rear bottom roll and rear gluing Roller, middle drawing rollers are to including middle

roll include roller shaft, and roller shaft is solid cylindrical structure, the preceding ride of a spinning frame The roller shaft integration of the rear bottom roll of all spindle positions in face is fixedly connected, the roller shaft of the middle bottom roller of all spindle positions is integrated Be fixedly connected, the roller shaft integration of the preceding bottom roll of all spindle positions is fixedly connected, the rear car table top of a spinning frame it is all The roller shaft integration of the rear bottom roll of spindle position, which is fixedly connected, the roller shaft integration of the middle bottom roller of all spindle positions is fixed connects Connect, the roller shaft integration of the preceding bottom roll of all spindle positions is fixedly connected, roller set is provided in the exterior circumference of roller shaft, Roller set is identical with the material of roller shaft and is irony or steel, rear bottom roll, middle bottom roller, preceding bottom roll roller set wrap Include left roller set, right roller set, left roller set, right roller set is integrated with roller shaft is fixedly connected, left roller set and right roller The length of set is identical, and the right end of the roller shaft of preceding bottom roll is driven by first motor to be rotated, the right side of the roller shaft of middle bottom roller It is sequentially connected between the right end of the roller shaft of end and preceding bottom roll by the first connection gear group, the right side of the roller shaft of rear bottom roll It holds and is sequentially connected between the right end the roller shaft of middle bottom roller by the second connection gear group, it is rear upper glue roller, middle upper glue roller, preceding Upper glue roller includes rubber roller, and rubber roller is irony material, and rubber roller is solid cylindrical structure, the rear ride of a spinning frame Face, the adjacent spindle position of one spindle position of front truck table top and right side constitute a spindle position group, in two spindle positions of a spindle position group Rear upper glue roller rubber roller integration connection, middle upper glue roller rubber roller integration connection, preceding upper glue roller rubber roller one Change connection, the rear upper glue roller of each spindle position, middle upper glue roller, preceding upper glue roller rubber roller exterior circumference on be cased with rubber roller set, Rubber roller set be rubber material, rear upper glue roller, middle upper glue roller, preceding upper glue roller rubber roller set include left rubber roller set, right rubber roller set, left glue Roller set, right rubber roller set are connect with rubber roller by respective intermediate bearing respectively, and left rubber roller set, right rubber roller set are respectively around rubber roller Independent rotation is covered, the length of the equal length that left rubber roller set and right rubber roller cover and respectively equal to left roller set and right roller set, The rear upper glue rollers of two spindle positions of one spindle position group, middle upper glue roller, preceding upper glue roller rubber roller set between rubber roller successively from rear In the rear insertion for being embedded in
