Description
Technical field
The utility model relates to a kind of yarn guiding device, belongs to technical field of textile machine.
Background technology
At present, known utilization convolution air stream is manufactured the method and apparatus of 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 of turning round, and forms a fiber feeding 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 to twist and turn round to mired on one side along the otch in the convolution direction of gyration airflow, on one side from the longitudinally shape of a side excision of one end, top major diameter.Exit region at fiber feeding passage is also provided with a concentric guid needle for resistance twist.Downstream position in this fiber feeding channel outlet district is provided with an annular minor air cell, has some spray-holes tangent with it on this minor air cell's perisporium, for to minor air cell's inject high pressure air, forms the air-swirl of convolution at a high speed in minor air cell.
In the spinning apparatus of above-mentioned employing, because the guiding face on fiber guiding part is made into the stubborn shape (being also the spiral of mired) of turning round 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, can not fully strengthen the fracture strength of yarn, in identical pressure and tangent spray-hole quantity situation, easily produces soft twist yarn
summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, a kind of yarn guiding device is provided, in identical pressure and tangent spray-hole quantity situation, it can improve the flow rotation speed of inside, minor air cell, improve eddy current cellulose is twisted to speed, effectively improve wandering fibre amount, finally reduce soft twist yarn mechanism of production, improved row yielding and the fracture strength of yarn.
The purpose of this utility model is achieved in that 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, to middle part, positive excision forms the second guiding face to described cylindrical guiding block matrix front end, described cylindrical guiding block matrix middle part to the positive excision of rear end locating piece forms the first guiding face, described the first guiding face gradient is greater than the second guiding face, described cylindrical guiding block matrix front end to the positive excision of conical boss front end forms the 3rd guiding face, between described the second guiding face and the 3rd guiding face, pass through arc surface transition.
On described outer casing back face, be provided with the locating slot matching with locating piece.
Described guiding block leading section boss and vortex tube inwall form vortex cavity.
Between described guiding block and shell, form lead-in cavity.
Compared with prior art, the utlity model has following beneficial effect:
A kind of yarn guiding device of the utility model, under same injection diameter, nozzle hole number and pressure, increase the eddy velocity of minor air cell's entrance, improve eddy current fiber has been twisted to speed, make fiber 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
Referring to Fig. 1, Fig. 2, a kind of yarn guiding device of the utility model, 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 ends, described columniform guiding block matrix 10 rear ends are provided with locating piece 11, to middle part, positive excision forms the second guiding face 12 to described cylindrical guiding block matrix 10 front ends, described cylindrical guiding block matrix 10 middle parts to the positive excision of rear end locating piece 11 forms the first guiding face 3, described the first guiding face 3 gradients are greater than the second guiding face 12, described cylindrical guiding block matrix 10 front ends to the positive excision of conical boss 7 front ends forms the 3rd guiding face 13, between described the second guiding face 12 and the 3rd guiding face 13, pass through arc surface transition.
On described shell 2 rear end faces, be provided with the locating slot matching with locating piece 11.
Cotton fiber forms lead-in cavity from guiding block and shell and enters the twisting of spinning spindle leading section and vortex cavity eddy current effect along guiding block surface under the effect of negative pressure, guiding block leading section boss vortex tube inwall forms vortex cavity, make in the time of same injection diameter and nozzle hole number, under same pressure, accelerate rotary speed, can not supply with chaotic because the disorder of gyration airflow causes fiber, increase more head end wandering fibre, do not make the twist toward front transfer, make yarn form non-complete open-end-spinning.
