Description
Technical field
The present invention relates to a kind of yarn guiding device, belong to technical field of textile machine.
Background technology
At present, the known method and apparatus utilizing convolution air stream to manufacture these spinning.Chinese patent CN1038438C discloses a kind of spinning apparatus, and it comprises a fiber guiding part, and it contains a mired and twists the spigot surface turned round, and forms a fiber feed passage with spinning apparatus entrance wall.It is roughly that one end, top diameter is large, little round table-like of one end diameter below that this fiber guiding part is made, and is twist turn round along the otch mired on the convolution direction of gyration airflow, while from one end, top major diameter longitudinally side shape of excising.At the exit region of fiber feeding passage, a concentric guid needle for resistance twist is also installed.At the downstream position in this fiber feeding channel outlet district, an annular minor air cell is installed, this minor air cell's perisporium has some spray-holes tangent with it, for inject high pressure air in minor air cell, in minor air cell, form the air-swirl of convolution at a high speed.
In the spinning apparatus of above-mentioned employing, shape (being also the spiral of mired) is turned round because the guiding face on fiber guiding part is made into the stubborn of mired, therefore its guiding part difficulty of processing is large, and the space, minor air cell of this kind of spinning apparatus is large, the flow rotation speed of inside, minor air cell is slow, eddy current is slow to fiber twisting speed, fully can not strengthen the fracture strength of yarn, under identical pressure and tangent spray-hole quantity situation, easily produce soft twist yarn
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of yarn guiding device is provided, under identical pressure and tangent spray-hole quantity situation, it can improve the flow rotation speed of inside, minor air cell, improve eddy current and speed is twisted to cellulose, effective raising wandering fibre amount, final minimizing soft twist yarn mechanism of production, improves row yielding and the fracture strength of yarn.
The object of the present invention is achieved like this: a kind of yarn guiding device, it comprises guiding block, shell and vortex tube, described guiding block is arranged in shell, described guiding block comprises columniform guiding block matrix and conical boss, described conical boss is arranged at columniform guiding block matrix front end, described columniform guiding block matrix rear end is provided with locating piece, described cylindrical guiding block matrix front end to front, middle part excision formation second guiding face, to locating piece front, rear end excision formation first guiding face in the middle part of described cylindrical guiding block matrix, described first guiding face gradient is greater than the second guiding face, described cylindrical guiding block matrix front end is to conical boss front end elevational excision formation the 3rd guiding face, by arc surface transition between described second guiding face and the 3rd guiding face.
Described outer casing back face is provided with the locating slot matched with locating piece.
Described guiding block leading section boss and vortex tube inwall form vortex cavity.
Lead-in cavity is formed between described guiding block and shell.
Compared with prior art, the present invention has following beneficial effect:
A kind of yarn guiding device of the present invention, the eddy velocity of minor air cell's entrance is increased under same injection diameter, nozzle hole number and pressure, improve eddy current and speed is twisted to fiber, fiber is made to have adequately expanded space in minor air cell, increase tail end wandering fibre amount, and coordinate hollow spindle pilot hole and vortex tube sidewall spacers, fiber is effectively stretched, increase hollow spindle central negative pressure and reduce the impact of axial flow on fibre bundle, reduce soft twist yarn mechanism of production, improve row yielding and fracture strength etc. and obtain high-quality yarn.

Detailed description of the invention
See Fig. 1, Fig. 2, a kind of yarn guiding device of the present invention, it comprises guiding block 1, shell 2 and vortex tube 6, described guiding block 1 is arranged in shell 2, described guiding block 1 comprises columniform guiding block matrix 10 and conical boss 7, described conical boss 7 is arranged at columniform guiding block matrix 10 front end, described columniform guiding block matrix 10 rear end is provided with locating piece 11, described cylindrical guiding block matrix 10 front end to front, middle part excision formation second guiding face 12, to rear end locating piece 11 front excision formation first guiding face 3 in the middle part of described cylindrical guiding block matrix 10, described first guiding face 3 gradient is greater than the second guiding face 12, described cylindrical guiding block matrix 10 front end is to conical boss 7 front end elevational excision formation the 3rd guiding face 13, by arc surface transition between described second guiding face 12 and the 3rd guiding face 13.
Described shell 2 rear end face is provided with the locating slot matched with locating piece 11.
Cotton fiber is formed from guiding block and shell and carries out spinning lead-in cavity enters spindle leading section and vortex cavity eddy current effect along guiding block surface and twist under the effect of negative pressure, guiding block leading section boss vortex tube inwall forms vortex cavity, make when same injection diameter and nozzle hole number, rotary speed is accelerated under same pressure, fiber will be caused to supply confusion because of the disorder of gyration airflow, increase more head end wandering fibre, do not make the twist toward front transfer, make yarn form non-fully open-end-spinning.
