Description
Technical field
The present invention relates to open-end spinning device according to the preamble of claim 1.
Background technology
This open-end spinning device just has been disclosed relatively with the gas flow spinning cup spinning machine very early and clearer and more definite description has for example been arranged in DE4227885C2 or DE102006033971A1 in many patent applications.
Such open-end spinning device especially has with high rotating speed rotating spinning rotary cup and fiber skein shredding mechanism in can accepting the revolving cup housing of negative pressure, and the opening roller that in the opening roller housing, rotates of fiber skein shredding mechanism will feed that shredding becomes filament to fiber skein.The opening roller housing has two openings this moment in the zone of the circumferential wall of at least partly surrounding opening roller; Feed and be admitted to the opening roller housing through said opening, passed on into the fiber guiding channel from feed the filament that dirt particles is removed and institute's shredding goes out that to being scattered the fiber skein from the opening roller housing to fiber skein.That is, in the zone of the first big relatively opening, be provided with the fiber skein feed roller, it is used for and can feeds the opening roller of giving rotation and become filament by the opening roller shredding feeding to fiber skein for groove with corresponding feeding relatively.In the shredding process, except that filament, also discharge dirt particles etc., its filament that goes out with shredding is pulled away through the opening roller or the swirl flow of rotating with opening roller.
Be arranged on to feed and be used at this moment first opening of opening roller housing is divided into fiber skein entrance area and the roughly spaced so-called dirt exit region that joins with the fiber skein entrance area to the fibre bundle bearing on the groove.If filament and the dirt particles taken away by opening roller arrive the dirt exit region; Then heavier dirt particles is thrown out of by centrifugal force decision ground, and filament is able to settle out and stays in the swirl flow zone perhaps on opening roller through the suction air component that flows into.
In several angular ranges behind the dirt exit region, the circumferential wall of opening roller housing has another obviously less opening, and it constitutes the entrance area of tapered fiber guiding channel.In addition; Be arranged on fiber guiding channel in second open area of opening roller housing circumferential wall is connected to the negative pressure accepted of open-end spinning device at outlet side revolving cup housing, this causes in the fiber guiding channel, occurring pointing to from the opening roller housing conveying air flow of revolving cup housing.Fiber guiding channel preferred so formation this moment and setting, that is, fiber guiding channel wall abuts against on the opening roller housing circumferential wall of surrounding opening roller as tangent line.
In the spinning operation; Because being present in the spinning negative pressure in the revolving cup housing negative pressure is arranged also in the entrance area of fiber guiding channel, this negative pressure with act on by opening roller accelerate to centrifugal force on the filament of approaching velocity of rotation be used to make filament to break away from opening roller or vortex flow and through the fiber guiding channel by the yarn revolving cup of pneumatic conveying to high speed rotary in the revolving cup housing.
Filament by the feeding spinning rotary cup is spun into yarn in spinning rotary cup, yarn is drawn out of and is wound into cross winding bobbin through unwinding yarn mechanism subsequently.
Though above-mentioned open-end spinning device and corresponding fiber skein shredding mechanism thereof are repeatedly proved useful in practice, in technological circle consistent think in fiber guiding channel zone, especially see and optimize potential in addition from the fluid technique angle.That is, not only in the fiber guiding channel the filamentary air of pneumatic conveying that is used for of onset flow and to look and can also improve that the flow condition in fiber guiding channel entrance area also can also improve.
Past has proposed various mechanisms, should improve the flow condition in fiber guiding channel and/or fiber guiding channel entrance area whereby.
DE-OS1925999 has for example described a kind of fiber skein shredding mechanism, and it is compared with above-mentioned fiber skein shredding mechanism and makes following improvement, that is, it has special compressed air and is blown into mechanism in fiber guiding channel zone.Compressed air is blown into and so constitutes mechanism at this moment and arrange that promptly, the filament of in the fiber guiding channel, carrying bears external air-flow effect, thereby prevents that filament from getting in the boundary layer that in the conduit wall zone, occurs and possibly slowed down there.
In addition, for example DE-OS2131270 discloses a kind of fiber skein shredding mechanism, and wherein, the part that is positioned at before the fiber guiding channel of surrounding the opening roller housing circumferential wall of opening roller has special tectonic, and is equipped with special pneumatic mechanism respectively.

Stipulate that in second embodiment additional being equipped with in widening portion zone of fiber transmission channel dwindled structure, and before dwindling structure, offers the steam vent that links to each other with negative pressure source.
But the described fiber skein shredding of DE-OS2131270 mechanism is proved to be not too favourable in corresponding research, and is not dropped into practical application.
DE3916238A1 and/or DE19857160A1 disclose other fiber skein shredding mechanism, and research here is the flow condition of favourable influence in fiber guiding channel zone how.Fiber skein shredding mechanism has been described in the above-mentioned patent application that requires to protect; Wherein, So improve acting in the fiber guiding channel, depend on the suction air flow of spinning negative pressure of machine self of outlet cross section and the current existence of fiber guiding channel as everyone knows; That is, the fiber guiding channel is equipped with additional by-pass prot and effective suction cross section of increased fiber guiding channel thus.
In the disclosed fiber skein shredding of DE3916238A1 mechanism, by-pass prot is opened in after the fiber guiding channel turns round a little, in the inner ring district of fiberless fiber guiding channel that generally tries one's best.But show that in corresponding research through such by-pass prot perpendicular to the setting of fibre transportation direction, what in the fiber guiding channel, carry is not that inconsiderable a part of filament is seen off, is siphoned away in other words.
DE19857160A1 relates to the improvement of the disclosed fiber skein shredding of DE3916238A1 mechanism.In this fiber skein shredding mechanism, by-pass prot is the part of channel plate joint and so is arranged in the channel plate joint holder zone that promptly, by-pass prot is located in by the fibre stream and in face of the fibre transportation direction.
Though capable of usingly facilitate the additive air amount in the fiber guiding channel and needn't improve the negative pressure in the spinning machine as the disclosed fiber skein shredding of DE19857160A1 mechanism, fiber skein shredding mechanism especially can also improve about its flow condition in the zone, ingate of fiber guiding channel.
