Away from the direction of combing roller case, the reduced diameter of defeated fibre passage.
A kind of spinning device eliminating vortex as above, the rotating speed of the diameter of described combing roller is 5000～
9000rpm.
The principle of the present invention is：
When defeated fibre passage is connected for turning with the side of combing roller case, air-flow flows to defeated fibre from the carding cavity of combing roller
During passage, due to the mutation of flow boundary region shape, air-flow can produce larger vortex near defeated fibre feeder connection.By defeated fibre
Passage is connected with the turning of combing roller case and is changed to after arc-shaped transition connects, because the change of air current flow border is gentle, therefore, gas
Stream will not produce compared with maelstrom near defeated fibre feeder connection, thus improving flow regime in defeated fibre passage for the air-flow.Point
When comb roller carding cavity interior air-flow is to defeated fibre channel flow, the streamline of more smooth-going can be formed, eliminate at defeated fibre feeder connection
Maelstrom.Therefore, stripped from combing roller sawtooth the ultimate fibre getting off move to defeated fibre passage when, due to vortex interference make
With being eliminated, fiber will not produce bending, be wound around, or even plurality of fibers tangles and forms tuberosity in vortex, so that fine
The form of dimension is improved, and the parallel stretch degree of fiber is improved.In resultant yarn, fiber alignment is better, bending, winding
Fiber number reduce, thus improve the quality of resultant yarn.Additionally, being disappeared using the circular sliding slopes of combing roller case and defeated fibre passage
After the vortex in defeated fibre passage, the air flow rate flowing to defeated fibre channel exit within the unit interval is also increased
Greatly.Because defeated fibre channel outlet area is certain, the flow increasing defeated fibre channel outlet increases the air-flow of defeated fibre channel outlet
Speed, then in defeated fibre passage to revolving cup collection surface in shift the speed of fiber and also increased, now, improve revolving cup fast
Degree, is beneficial to improve resultant yarn yield.
The size of the vortex that defeated fibre feeder connection is formed about mainly is affected by negative pressure in revolving cup.In spinning device
Impurity discharging port serve not only as the outlet of despumation, also serve as the entrance to supplemental air flow in revolving cup.Due to impurity discharging port and the external world
Air is connected, and its air pressure is consistent with local atmospheric pressure, therefore, when revolving cup internal negative pressure increases, inside revolving cup and impurity discharging port
Pressure reduction also increase.Pressure reduction increases will be bigger for the speed making the air-flow of flowing in combing roller carding cavity is to revolving cup, and flowing is more
For rapid, then the intensity of the vortex being formed about in defeated fibre feeder connection and size are also bigger.Circular arc of different sizes to defeated fibre
Air flow state at feeder connection plays the role of different, and larger vortex can be made when circular arc is larger to be eliminated, therefore,
When in revolving cup, negative pressure increases, corresponding circular arc also will increase.Using the method for computer simulation, can be in the hope of in difference
The size of the circular arc being adopted under negative pressure in revolving cup cup, therefore can be in the hope of the relation of arc radius and negative pressure in revolving cup cup.
Beneficial effect：
A kind of spinning device of the present invention, combing roller case and defeated fibre passage are connected as that side that turning is connected and change
For circular sliding slopes, the vortex that combing roller stripping area is transitioned in this segment space region of defeated fibre passage can be eliminated, increasing should
The space of effective conveying fiber in area of space.When by defeated fibre passage, be not vortexed disturbs fiber, reduces fiber
Produce the probability of the bad forms such as bending, crotch, doubling, winding, improve the degree of orientation and the parallel stretch degree of fiber.Becoming knot
In structure, the form of fiber is more good, and the fiber number of the bad form such as bending, crotch and winding reduces so that the matter of resultant yarn
Amount is improved.Additionally, eliminating the vortex at combing roller stripping area and defeated fibre feeder connection, also can effectively increase defeated fibre passage
Outlet air flow rate, thus increase defeated fibre channel exit air velocity, then within the unit interval, from defeated fibre passage to
The speed of fiber is shifted faster in revolving cup collection surface.Again because increasing rotational speed of rotor can improve yield, increasing rotational speed of rotor will
Fibre deposition in revolving cup collection surface in the unit interval is asked to obtain faster, therefore this spinning device is also beneficial to improve resultant yarn yield.
