Description
Technical field
The invention belongs to spinning machine technical field, relate to a kind of spinning organ, particularly relate to the spinning organ of a kind of rotor spinning machine, be exactly that two sets are fed for opening box juxtaposition and have the spinning organ of rotor spinning machine of two passages and only one of which revolving cup specifically.
Background technology
Along with the fast development of textile industry, improving constantly of automatization level, present various novel spinning mode.Wherein, spinning speed is high, package capacity is big, spin ability is preferable and double can spin excellent low raw material and the feature of lower-grade feedstock owing to it has for rotor spinning machine, it has also become the spinning form that in Advanced Spinning Technologies, technology is the most ripe, application surface is the widest, economy is higher.Large-scale industrial application is put into so far from 20 century 70s, through the development of more than 40 years, Revolving cup spinning product, from the coarse cloth at initial stage, vamp cloth, the tablecloth etc., develops into denim of today, slubbed fabric, poplin cloth and knitwear etc., and various non-cotton products are also in exploitation energetically.
Rotor spinning belongs to open-end-spinning technology field.As far back as 1872, in the U.S., just someone applied for patent in open-end-spinning, but due to a variety of causes, four or five afterwards during the decade, are at developing and experimental stage, hence without the requirement reaching industrialized production always.Along with first former Czechoslovakia produce First KS-200 type rotor spinning machine model machine in the world in the sixties in last century, several years afterwards are the most constantly improved, within 1967, manufacture out First performance more advanced, can be used for the BD-200 type rotor spinning machine of industrialized production.Japan, Germany study and improve subsequently, and the technology of rotor spinning obtains the progress advanced by leaps and bounds, and occurs in that from air draft and air suction type rotor spinning machine.And along with the raising of automatization level, rotor spinning also achieves automatization's joint, although result is repeatedly improved, the overall structure of the critical component spinning organ of Revolving cup spinning is all the time without large change.The basic structure of existing spinning organ includes housing, case, defeated fine passage between the rotating cup seat containing suction muffler being arranged on spinning machine main frame spinning machine girder, the revolving cup in rotating cup seat and combing roller, feed roller, doffing tube and combing roller and the revolving cup being arranged on housing.Due to tradition spinning organ list set point comb, make Revolving cup spinning have bigger application in terms of the pure textile product of cotton spinning, but be also adopted by having bigger restriction and problem when Revolving cup spinning produces the new type yarns such as mixed yarn, short and thick slub, fancy yarn simultaneously.Main reasons is that, owing to different model combing roller is different to the scope of application of raw material, same opening box is difficult to that different performance fiber is had good combing simultaneously, therefore, limits the multiformity of rotor spinning kind to a certain extent.Therefore expanding the range of application of Revolving cup spinning, the kind of abundant rotor yarn, it is necessary to improve the critical component spinning organ of Revolving cup spinning, particularly design are double is fed for carding agencies.
Summary of the invention
The invention provides a kind of spinning organ, particularly provide the spinning organ of a kind of rotor spinning machine, a kind of two sets to be fed for opening box and side by side and there is the spinning organ of rotor spinning machine of two passages.Instant invention overcomes tradition spinning device is fed for point comb and a conveying mechanism defect in structure and performance, it is provided that a kind of spinning device with stronger practicality and higher economic worth.
