Embodiment
A kind of spinning jet nozzle of sir jet spinning machines, including drafting system 25 are present embodiments provided, which includes
Multiple corresponding drafting system rollers 24, fibre bundle 2, the tow transport for example in the form of bifilar drafting machine sliver to the drawing-off
System roller 24.In principle, sir jet spinning machines shown in further include the formation yarn unit 33 being spaced apart with drafting system 25 and
The formation yarn members 8 of hollow spindle form shown in Figure 2, the formation yarn unit have following shown in the accompanying drawings
Built-in spinning jet nozzle 3, wherein spinning jet nozzle 3 at least partially define minor air cell 6.In minor air cell 6, fibre bundle 2 or fiber
At least part fiber of beam 2 is provided with protection and twists.
Sir jet spinning machines can also include (the drawing of drawing unit 27 with preferably two pulling rollers 26 for rove 1
Unit 27 is not indispensable).There is typically further be arranged in drawing unit 27 or form the winding dress in 33 downstream of yarn unit
31 are set, which should include at least one pipe driver 30 again and connect respectively with pipe driver 30 and in principle
The pipe holder for knowing (but being not shown), by the pipe holder, pipe 29 can be fixed and be placed in rotation by pipe driver 30
During transhipment is dynamic, so as to be wound up on pipe 29 by rove 1, preferably by the support of traversing unit 28.
Sir jet spinning machines is according to special air-jet spinning technique come work.In order to form rove 1, fibre bundle 2 is along conveying side
It is directed in the minor air cell 6 for the spinning jet nozzle 3 to form yarn unit via following attached entrance opening 4 not shown in the figure to T.
Fibre bundle obtains protection and twists there, that is to say, that at least part fiber of fibre bundle 2 is by the spinning by suitably arranging
The air stream that air duct 9 generates is caught.Therefore, a part of fiber pulls out at least a small amount of distance and is twined from fibre bundle 2
It is wound on the tip for the formation yarn members 8 being projected into minor air cell 6.
Finally, the fiber of fibre bundle 2 to be formed via the entrance opening 35 (participate in Fig. 2) for forming yarn members 8 and being arranged in
The drawing channel 34 of inside yarn members 8 and adjacent entrance opening 35 is drawn out from minor air cell 6.Here, last free
Fiber end also pulls in the direction of helical trajectory upper edge entrance opening 35 and is wrapped in center traveling as winding fiber
Around core fibre, the rove 1 that there is desired protection to twist is obtained.
Due to the twisting of the only part of fiber, rove 1 has a drawability, the drawability for downstream spinning machine,
Such as in ring spinner be further processed rove 1 for be essential.On on the other hand, traditional air-jet spinning dress
It sets and significant twirl is applied to fibre bundle 2 so that necessary drawing-off cannot be carried out again after yarn production.In this case,
This is also desirable, because conventional sir jet spinning machines is designed to that production finished yarn, the finished yarn are generally intended to height
Intensity is characterized.

There is the outside 12 for limiting spinning jet nozzle 3 outward and limits the inside 13 of minor air cell 6 (wherein in general, vortex chamber wall 5 can also be by more
A component is formed).Finally, setting spinning air duct 9 can will be spinned by the spinning air duct during producing yarn
Air is introduced into minor air cell 6, wherein spinning air duct 9 has spinning air entry apertures 10 and is passed through in minor air cell 6
Spinning air outlet slit opening 11.
Spinning jet nozzle 3 includes spinning air duct 9 and multiple connector air ducts 14, in above-mentioned bond process, pressure
Contracting air can be introduced by these connector air ducts in minor air cell 6, so as to inside minor air cell 6 particularly directed to
Bond process generates the vortex-like air stream of optimization.Connector air duct 14 from connector air entry apertures 15 at least partly with it is defeated
It send direction T-phase instead to extend, the connector air entry apertures 15 of connector air duct 14 is placed on accordingly along conveying direction T
The downstream of connector air outlet slit opening 16, connector air duct 14 are passed through in minor air cell 6 by connector air outlet slit opening, are connect
Head air duct 14 preferably includes at least one first passage section 17 and at least one second channel section 18, wherein first is logical
Road section 17 is transitioned into from connector air entry apertures 15 in second channel section 18, and the second channel section is eventually by connector
Air outlet slit opening 16 is passed through in minor air cell 6.
Here, two channel sections 17,18 surrounded by angle α, the range which preferably mentions in general describe
It is interior.Furthermore it is advantageous that the central axis 32 that first passage section 17 is parallel to spinning jet nozzle 3 extends.
The sequencing of above example is only for ease of description, can not represent the quality of embodiment.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
