Description
Technical field
The utility model belongs to spinning equipment field, is related to a kind of Revolving cup spinning navel, more particularly to a kind of to have table
Face is provided with the Revolving cup spinning navel of narrow slit.
Background technology
Rotor spinning is also known as open-end spinning in China and turned, and is one kind of Advanced Spinning Technologies, belongs to open-end-spinning work
Skill category.Because rotor spinning has, production efficiency is high, resultant yarn strand is good, technological process is short, work situation good, automaticity
High the advantages of, be a kind of current most popular novel spinning form.More popularized in China's rotor spinning, 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, the strip produced by carding machine is had in more defect, such as strip in quality containing more short
Fiber, impurity and fault, the extended parallelization of fiber are also poor.Road processing, yarn quality and resultant yarn after these defects can influence
Fineness.Combing just refers to that the other end is combed when fiber must be held from one end, thus in combing to fine impurities and
The exclusion of chopped fiber, to stretch fiber be very effective.Cotton noils refers to that strip is combed down by combing process during cotton spinning
That comes contains the short fine and more raw material of impurity.
During high grade cotton yarn following using Revolving cup spinning cotton noils 14.7tex, because fibre length is shorter in cotton noils, spinning
It is strongly relatively low, breakage phenomena is easily produced during spinning, this is the main limiting factor for restricting Revolving cup spinning high-count yarn spun.Through dividing
Analysis, during rotor spinning, yam breakage phenomena typically occurs in yarn and peeled off with revolving cup collection surface to the path of navel, revolving cup
Spin the retaining element that navel is provided in revolving cup and is located at turn around position of center line.Fixed 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 yarn arm and twist increase at collection surface stripping,
The dynamic tenacity of sliver at the design twist or increase pick-up point of rotor spinning can be reduced, the reduced effect that breaks end is reached.False twisting
The false twisting degree of disk depend on the material (steel, ceramics etc.) of false twisting panel surface, shape (disk radius of curvature, external diameter, aperture etc.) and
Feature (quantity, position, form, surface treatment mode of groove etc.).Prior art is improves the false twist efficiency of navel, generally
The cambered surface of navel is handled in navel, groove can be typically carved with the cambered surface of navel (not through perforate false twisting
The upper bottom surface and bottom surface of disk) or it is raised, make the roughness increase of the cambered surface of navel, so as to increase yarn in false twisting dish cart
Frictional force on face, but rely solely on and change the form of navel cambered surface limited is improved to the false twist efficiency of navel, when spinning one
During a little special yarns, the false twisting effect played is general or limited.And in navel cambered surface during fluting, use time is long
Afterwards, inside grooves, which can accumulate, dust or impurity, so as to reduce the service life and false twist efficiency of navel.Therefore, how
The false twist efficiency of navel is improved, the broken end for effectively reducing rotor spinning is the technical issues that need to address.
Utility model content
Technical problem to be solved in the utility model is that there is provided a kind of Revolving cup spinning false twisting in view of the shortcomings of the prior art
Disk, particularly a kind of navel body cambered surface surface is provided with the Revolving cup spinning navel of narrow slit.
A kind of Revolving cup spinning navel, navel body cambered surface part is provided with narrow slit, and the narrow slit runs through the navel sheet
The upper and lower bottom surface of body cambered surface part, the area of section of the narrow slit is 0.11-2.5mm2.The narrow slit is connected with extraneous blower fan,
In rotor spinning, the portion gas in revolving cup can be flowed out by through hole, and producing extraneous negative pressure can adsorb yarn on narrow slit,
It can increase institute's yarn and the rubbing action of navel body cambered surface part, so as to strengthen the false twisting effect of navel, improve
The twist of yarn can keep relative stability state in the false twist efficiency of navel, spinning process, and the weak twist position in yarn can phase
To reducing, the strength of yarn can more be stablized, because the breakage phenomena of rotor spinning is mainly due to weak twist present in yarn
Yarn strength is irregular caused by position, therefore, improves the false twist efficiency of navel, can effectively solve the disconnected of rotor spinning
Head.Compared with not through the mode cracked, the navel of the present utility model for being provided with through hole, can be with due to the effect of negative-pressure air-flow
Yarn is set to contact closer with navel cambered surface, the false twist efficiency of navel is higher, the twist for spinning rotor yarn is more stable.
In spinning process, from the narrow slit that area is larger, it increase effectively pumping area, it is not easy to by impurity or ash
Dirt is blocked, and does not interfere with resistance twist effect, is more beneficial for the discharge of impurity or dust, the false twisting of navel is acted on more preferable.
It is used as preferred technical scheme：
A kind of Revolving cup spinning navel as described above, the width of the narrow slit is 0.05~0.5mm, and the length of narrow slit is
2.2~5mm.
A kind of Revolving cup spinning navel as described above, the narrow slit is distributed in yarn and drawn out of revolving cup and navel cambered surface
The cambered surface part that is connected with navel cambered surface between contact of initial contact point to doffing tube.
A kind of Revolving cup spinning navel as described above, narrow slit is opened up along navel body cambered surface part generatrix direction.Will be narrow
Seam arrangement is into strips, it is ensured that yarn is acted in the whole cambered surface contacted with navel by continual and steady air-flow,
So as to effectively improve resistance twist effect.
A kind of Revolving cup spinning navel as described above, the number of the narrow slit is 1-10 bars.
A kind of Revolving cup spinning navel as described above, the cross sectional shape of the narrow slit is square seam or waist type seam.
The cross sectional shape of narrow slit is phase in a kind of Revolving cup spinning navel as described above, the navel body cambered surface part
It is same or different.
A kind of Revolving cup spinning navel as described above, the material of the navel body cambered surface part is ceramics or steel.

Material it is also contemplated that.
The revolving cup spinning method of Revolving cup spinning navel as described above, the revolving cup spinning method includes yarn in navel
False twisting step, during false twisting, navel is placed in the revolving cup of spinning device, extraneous blower fan passes through in navel body cambered surface
Through hole extract gas in revolving cup, the size for making to produce negative pressure in negative pressure, the revolving cup in revolving cup is -300~-500Pa.It is false
During sth. made by twisting, external wind chance is evacuated by narrow slit, and the air-flow for turning interior is extracted out by narrow slit by extraneous blower fan, is made in revolving cup and navel
The upper surface of body cambered surface produces negative pressure, and then because suction function makes the yarn docile in the navel body cambered surface
On surface, the frictional force between the navel body cambered surface and yarn is increased, the false twist efficiency of the navel is improved.
Beneficial effect
