Description
Technical field
The present invention relates to a kind of spinning element, more particularly to a kind of rotor spinning Yarn guide device.
Background technology
Fibre bundle has been incorporated into spinning room by rotor spinning machine by a point comb unit, and single fiber will strike at a high speed
Single fiber can be thrown in rotor slot region by the inwall of the spinning rotor of rotation, then, caused centrifugal force.Finally, spin
The rotation of rotor can cause single fiber to twist, and these single fibers again can wind caused yarn end
Firmly, the torsion of single fiber can constantly produce yarn, finally, can be via the doffing tube for accordingly drawing yarn unit, by yarn from spinning
Yarn extracts in room.
But the intensity of false twisting that yarn is applied in spinning process can be restricted, if the false twisting applied is excessive,
Excessive mechanical load can be then produced to yarn, the damage of yarn can be caused, cause yam surface crude, filoplume increases, even
Broken yarn.
The content of the invention
It is therefore an object of the present invention to a kind of rotor spinning Yarn guide device is provided, can be during rotor spinning
Apply the twisting of sufficient intensity to yarn, and avoid yarn from bearing excessive mechanical load.
The present invention is achieved through the following technical solutions：
A kind of rotor spinning Yarn guide device, including extend into rotor spinning machine spinning it is indoor draw yarn mouth, and for will
The doffing tube that the yarn of generation extracts in spinning room, wherein, draw yarn direction in the yarn extracted from spinning room
On, doffing tube is installed in the downstream position for drawing yarn mouth, it is characterised in that and the doffing tube includes spiral extension,
Formed with some projections on the surface of the extension, by the structure, false twisting can be applied to the yarn drawn inside yarn mouth
On.
The spiral extension section is limited by the surface section of insert.
The insert is surrounded by inwall, also, the surface section of the insert towards inwall has helical form sunk structure,
Its adjacent part with inwall together form spiral extension section.
The insert and the yarn unit member that takes with inwall are single components.
Component with interior wall construction is made up of sleeve, and the installation site of the insert is in the sleeve
Inside, also, the installation of the sleeve is non-rotatable.
The insert and the sleeve are bonded together, and the sleeve draws described yarn mouth and connected with tube is drawn
Together, wherein, the insert is installed in draw yarn mouth and draw tube between, and surrounded by the sleeve (30).
Make smooth low friction, raised bump height formed with some raised surfaces on the surface of the extension
For 1-1.5mm, raised distribution density is 2-3/square centimeter.
Using above-mentioned technical proposal, have the advantages that：
By the guide device, in the spiral extension section of the doffing tube of Revolving cup spinning, yarn can be by moment of torsion control, and the torsion
Square can allow the yarn to be rotated around its longitudinal axis, in doffing tube region, by yarn and doffing tube spiral extension section
Contact between wall, it is possible to realize and rotated caused by the yarn, yarn passes through the guiding of helical orbit, avoids false twisting torsion
The excessive influence to yarn mechanical performance of square, the projection for extending spirally section surface serve and make that yarn main body is loose, filoplume is docile and obedient
Effect.

Embodiment
Shown in reference picture 1-3：
Rotor spinning Yarn guide device, have to extend into rotor spinning machine spinning room 22 and draw yarn mouth 21, and for inciting somebody to action
The doffing tube 23 that the yarn 5 of generation extracts in spinning room 22, wherein, in the yarn 5 extracted from spinning room (22)
Draw on yarn direction, the doffing tube 23 is installed in the downstream position for drawing yarn mouth 21, it is characterised in that the doffing tube 23
Including spiral extension 24, formed with some projections on the surface of the extension, by the structure, false twisting can be by
It is applied to and draws on the internal yarn 5 of yarn mouth (21).The spiral extension section 24 is limited by the surface section 26 of insert 25
It is fixed.The insert 25 is surrounded by inwall 27, also, towards inwall 27 insert 25 surface section 26 have helical form and
The preferably sunk structure 28 of slot-like design, its adjacent part 29 with inwall 27 together form spiral extension section 24.Insert
Enter part 25 and be single component with the yarn unit member that takes of inwall 27.Component with the structure of inwall 27 is by sleeve 30
Form, and the installation site of the insert 25 is inside the sleeve 30, and also, the installation of the sleeve 30 is not
Rotatably.The insert 25 is bonded together with the sleeve 30.The sleeve 30 draws the He of yarn mouth 21 by described
Draw tube 14 to be connected together, wherein, the insert 25 is installed in draw yarn mouth 21 and draw tube 14 between, and by institute
Sleeve 30 is stated to surround.Make smooth low friction formed with some raised surfaces on the surface of the extension, it is raised
Bump height is 1-1.5mm, and raised distribution density is 2-3/square centimeter.
The spiral extension section 24 according to the present invention is made up of an insert 25, and the insert 25 is arranged
Drawing inside the doffing tube 23 of yarn mouth 21, the yarn mouth 21 of drawing can also be substantially used in rotor spinning machine.It is inserted into
The insert 25 in doffing tube 23 has a columned exterior contour, and the exterior contour and the limitation of yarn mouth through hole
The in-profile of inwall 27 is corresponding.In addition, in the adjacent surface section 26 of above-mentioned inwall 27, insert 25 also has a spiral shell
Shape sunk structure 28 is revolved, according to the type of helix, the sunk structure 28 can be by the upper surface of the insert 25 around firmly.
And it is external, being preferably designed for the sunk structure 28 of channel-shaped will be limited by the sunk structure 28 of the adjacent part 29 of inwall 27.
Therefore, a doffing tube 23 including spiral extension section 24 can be obtained, is gone out from the spinning room 22
During that comes draws yarn, yarn 5 must pass through from described section 24.Wherein, if helical form rotation direction, with appearing in yarn
The rotation direction of yarn 5 in entrance 15 is consistent, then, in the region of insert 25, the rotation will be strengthened.Most
Eventually, corresponding false twisting may proceed to propagate the groove for reaching the spinning rotor 4 (dividing comb to open again after insert 25)
It is interior, there, it may ensure that the fibres bond of the end of yarn 5 is very firm, wherein, while false twisting is generated, by spiral shell
The rounding limiting surface of shape extension 24 is revolved, this process hardly produces any extra mechanical load to the yarn 5,
The projection for extending spirally section surface serves the effect for making that yarn main body is loose, filoplume is docile and obedient.
It should be noted last that above embodiment is merely illustrative of the technical solution of the present invention and unrestricted,
Although the present invention is described in detail with reference to preferred embodiment, it will be understood by those within the art that, can be right
Technical scheme is modified or equivalent substitution, and without departing from the spirit and scope of technical solution of the present invention, its is equal
It should cover among scope of the presently claimed invention.
