Abstract
The invention relates to a dual feed carding mechanism, in particular to a dual feed carding mechanism of a rotor spinning machine. The dual feed carding mechanism comprises two independent feeding devices, two independent carding devices and two channels. The left and right feeding devices are arrayed symmetrically; the left and right carding devices are arrayed symmetrically, and left and right carding rollers, as the main components, are respectively arranged in left and right carding cavities; the left and right channels are respectively communicated with the left and right carding devices. According to the dual feed carding mechanism, features of a feeding carding mechanism of a traditional rotor spinning machine are changed, original single fiber feeding and carding is replaced with dual fiber feeding and carding during rotor spinning, the single fibers entering the rotor are provided with two independent channels, defects of the rotor spinning for blended yarn spinning and novel yarn production are overcome accordingly, using field of the rotor spinning is expanded effectively, and varieties of rotor yarns are enriched.
Description
Technical field
The invention belongs to spinning machine technical field, relate to a kind of two feeding to carding agencies, particularly relate to the two of a kind of spinning device and feed to carding agencies, specifically a kind of two covers are fed to opening box side by side and have the feeding to carding agencies of spinning device of two passages.
Background technology
Along with the fast development of textile industry, improving constantly of automatization level, presents various novel spinning modes.Wherein, spinning speed is high, package capacity large, spinning suiting is better and can doublely spin excellent low raw material and rudimentary raw material because it has for rotor spinning machine, has become the spinning form that in Advanced Spinning Technologies, technology is the most ripe, application surface is the widest, economy is higher.Apply so far from the 20 century 70s technical scale that has high input, 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, afterwards four or five during the decade, be all in development and experimental stage always, thereby do not reach the requirement of suitability for industrialized production.Along with first former Czechoslovakia produce First KS-200 type rotor spinning machine model machine in the world in the sixties in last century, in afterwards several years, constantly improve again, within 1967, manufacture out First performance more advanced, can be used for the BD-200 type rotor spinning machine of suitability for industrialized production.Japan, Germany study and improve subsequently, and the progress that the technology of rotor spinning obtains advancing by leaps and bounds, has occurred from air draft and air suction type rotor spinning machine.And along with the raising of automatization level, rotor spinning has also been realized automation joint, although result is repeatedly improved, the overall structure of the critical component of Revolving cup spinning---spinning organ is all the time without larger variation.The basic structure of existing spinning organ comprises that housing, case, one are arranged on revolving cup in rotating cup seat of the rotating cup seat containing suction muffler on spinning machine main frame spinning machine girder, and are arranged on the defeated fine passage between combing roller, feed roller, doffing tube and combing roller and the revolving cup on housing.Due to traditional spinning organ list cover point comb, make Revolving cup spinning have larger application aspect the pure textile product of cotton spinning, but have larger restriction and problem while also adopting Revolving cup spinning to produce the new type yarns such as blended yarn, short and thick slub yarn, Fancy Yarns simultaneously.Chief reason is because different model combing roller is different to the scope of application of raw material, and same opening box is difficult to that different performance fiber is had to good combing simultaneously, therefore, has limited to a certain extent the diversity of rotor spinning kind.Therefore expand the range of application of Revolving cup spinning, enrich the kind of rotor yarn, must be to the critical component of Revolving cup spinning---spinning organ improves, particularly design is two feeds to carding agencies.
Summary of the invention
