Abstract
The invention discloses a rotor spinning false twister. Through holes penetrating a cambered surface are formed in the cambered surface of a false twister body and connected with external fans, and air exhaust functions are achieved. When yarns are spun in a rotor spinning manner, the yarns can be adsorbed at the through holes by external negative pressure, friction action among the spun yarns and the cambered surface of the false twister body can be increased, so that false twisting action of the false twister is enhanced, and end breakage is decreased when the yarns are spun in the rotor spinning manner. The rotor spinning false twister can effectively solve the problem of end breakage in rotor spinning of combed noil yarns below 14.7tex, and can help enterprises to effectively upgrade industries and save production cost.
Description
Technical field
The invention belongs to spinning equipments field, relate to a kind of Revolving cup spinning navel, particularly relate to a kind of navel cambered surface
Part has the Revolving cup spinning navel of through hole.
Background technology
Rotor spinning is also called open-end spinning in China and turns, and is the one of Advanced Spinning Technologies, belongs to open-end-spinning work
Skill category.Owing to rotor spinning has, production efficiency is high, resultant yarn strand is good, technological process is short, work situation is good, automaticity
Advantages of higher, is current most popular a kind of novel spinning form.In China, rotor spinning is the most universal, the production of its cotton yarn
Total amount is only second to ring spinning.Thus, rotor spinning also has large effect in spinning industry, plays very important work
With.
During cotton spinning, carding machine the strip produced has more defect in quality, as in strip containing more short
Fiber, impurity and fault, the extended parallelization of fiber is the most poor.These defects can affect after road processing, yarn quality and resultant yarn
Fineness.Combing refers to when fiber must be held from one end, the other end by combing, therefore in combing to fine impurities and
The eliminating of chopped fiber, to stretch fiber be very effective.Cotton noils refers to during cotton spinning that strip is through combing process under combing
The raw material more containing short fibre and impurity come
When utilizing the Revolving cup spinning following high grade cotton yarn of cotton noils 14.7tex, owing in cotton noils, fibre length is shorter, spinning
The most relatively low, easily produce breakage phenomena during spinning, this is the main limiting factor of restriction Revolving cup spinning high-count yarn spun.Through dividing
Analysis, during rotor spinning, yam breakage phenomena typically occurs in yarn and peels off to the path of navel with revolving cup collection surface, revolving cup
Spin in navel is provided in revolving cup and be located at turn around the retaining element of position of center line.Fixing navel is to high speed in revolving cup
The yarn arm of revolution produces friction and causes false twisting, and the twist of final output yarn is constant, but at yarn arm and collection surface stripping, the twist increases,
The design twist of rotor spinning can be reduced or increase the dynamic tenacity of sliver at pick-up point, reaching the effect that broken end reduces.False twisting
The false twisting degree of dish depend on the material (steel, pottery etc.) on navel surface, shape (dish radius of curvature, external diameter, aperture etc.) and
Feature (quantity of groove, position, form, surface treatment mode etc.).Prior art is to improve the false twist efficiency of navel, generally
At navel, the cambered surface of navel is processed, typically can be carved with groove in the cambered surface of navel and (not run through perforate false twisting
The upper bottom surface of dish and bottom surface) or protruding, make the roughness of the cambered surface of navel increase, thus increase yarn at false twisting dish cart
Frictional force on face, but rely solely on the form changing navel cambered surface and the false twist efficiency of navel is improved limited, when spinning one
During a little special yarn, the false twist efficiency played is general or limited.And in navel cambered surface during fluting, use overlong time
After, inside grooves can be accumulated dust or impurity, thus reduces service life and the false twist efficiency of navel.Therefore, how
Improving the false twist efficiency of navel, the broken end effectively reducing rotor spinning is the technical issues that need to address.
Summary of the invention
The technical problem to be solved is for the deficiencies in the prior art, it is provided that a kind of Revolving cup spinning navel, special
It it not a kind of navel body cambered surface part Revolving cup spinning navel of having through hole.
A kind of Revolving cup spinning navel of the present invention, navel body cambered surface part has through hole, the cross section of described through hole
Amass is 0.05～0.1mm2,, described through hole runs through the upper and lower bottom surface of navel body cambered surface part.Described through hole and extraneous blower fan
Being connected, when rotor spinning, the portion gas in revolving cup can be flowed out by through hole, and producing extraneous negative pressure can be by yarn absorption logical
Kong Shang, can make institute's yarn strengthen with the rubbing action of navel body cambered surface part, thus strengthen the false twisting effect of navel,
Improving the false twist efficiency of navel, in spinning process, the twist of yarn can keep relative stability state, the weak twist position in yarn
Can relatively reduce, the strength of yarn can more be stablized, owing to the breakage phenomena of rotor spinning is mainly due to present in yarn
Weak twist position and the yarn strength that causes is irregular, therefore, improve the false twist efficiency of navel, can effectively solve rotor spinning
Broken end.Compared with the mode not running through perforate, the navel effect due to negative-pressure air-flow having through hole of the present invention, can make
Yarn contacts tightr with navel cambered surface, and the false twist efficiency of navel is higher, and the twist of spun rotor yarn is more stable.
