Description
Technical field
Invention relates to a kind of air nozzle device that produces line, it has a minor air cell and an annular waste air duct of discharging minor air cell's spinning air, and the latter has one to be used for the connecting hole of low pressure source and to have an air admission hole that is linked in the annular waste air duct at least.
Background technology
This air nozzle device is to be the prior art of representative with DE10311826A1.Everybody is placed in after the drafting system with a pair of feeding roller by known this aerojet device, wherein inhale the cleaning passage in hole for feeding roller to having disposed a band, it plays feeding roller keeping clean and flyings being siphoned away circumferential surface from feeding roller.In order to obtain air nozzle device simple structure as much as possible, cleaning passage is linked into annular waste air duct.Cleaning passage and annular waste air duct are connected to a shared low pressure source.
Show that now set annular waste air duct deposition usually takes place easily and stops up, this exhaust passage is to arrange round having a spindle shape assembly that draws yarn channel with one heart, draws the yarn channel resultant yarn by this and is drawn.Annular waste air duct mainly is the spinning air of discharging the minor air cell.Air is with the very high-speed minor air cell that pours in although spin, and produces the air-jet eddy-current of the fiber strip of the importing spinning twist of rotation at a high speed at this place, and owing to the compressed-air atomizer diameter is very little, the leaked-in air amount is not big especially.This interior flowing velocity of annular waste air duct that the cross section expansion is arranged that just causes being connected to the minor air cell significantly descends.Since less air velocity, the ability drop of air transportation impurity and flyings.Thisly from the spinning air that the minor air cell discharges inevitably impurities therefore be deposited in the annular waste air duct, and can cause as time passes stopping up at this.This deposition can influence spinning process, and final the interruption spinned.Have only in the annular waste air duct zone very little air flow with and the sedimental zone of interior main generation all be called " dead band ".
Document DE10311826A1 discloses a kind of cleaning passage, its suction hole is configured in feeding roller to locating and this passage access annular waste air duct, what thereby additional flyings arrived at the circular passage is easy to the zone stopped up, thereby has strengthened failure-frequency more.Although this cleaning passage is used as an air admission hole simultaneously, extra air enters annular waste air duct and partly improves air velocity herein by this hole, does not obtain effect owing to contain impurity.In addition, air admission hole is being linked into annular waste air duct near the place, minor air cell.And all be to form sedimental dead band dorsad in these terminal areas of the annular waste air duct of minor air cell.
Not that this type of other document DE19501545A1 has described a kind of method that starts spinning process on an air nozzle device.When spinning process in the described beginning of this patent, a loose thread is in reverse to the spinning direction and enters in the air nozzle device, and the spinning process of interruption relies on this root loose thread to be continued.A compressed air supply hole is set, and this supply hole is linked into annular waste air duct and this hole and supplies with compressed air in spinning short time of process in the beginning.Compressed air stream is to be used for cleaning the air nozzle device that the beginning opened before spinning on the one hand, is on the other hand to be used for proofreading and correct and to stretch by in contrast to the loose thread that draws the input of yarn direction.So-called compressed air supply hole is no air admission hole in this invention, because clear and definite regulation does not have air to import the air nozzle device via the compressed air supply hole during regular spinning process.
Summary of the invention
Task of the present invention is, improves the job stability of the described this air nozzle device of beginning and at utmost reduces the production fault that causes owing to deposition in the exhaust passage.
The solution of task is, has at least an air admission hole to be linked into annular waste air duct in the zone of connecting hole dorsad.
Thus advantageously, largely prevent to exist the dead band in annular waste air duct, speed air flow produces deposit slowly and therefore in these dead bands.Air admission hole stands facing each other basically and settles in connecting hole, can reach good effect more.Therefore, the spindle shape assembly that is surrounded by annular waste air duct is as benchmark.Because air admission hole and connecting hole are not compulsory accurately radially being placed on the circular passage, for obtaining good effect, the position of the transitional region between air admission hole or connecting hole and annular waste air duct is conclusive.With the spindle shape assembly is benchmark, and the transitional region in preferably from air admission hole to annular waste air duct is arranged to relative with the transitional region from annular waste air duct to connecting hole.
A zone that is easy to generate deposition especially is to be in the terminal area of the annular waste air duct of minor air cell dorsad in annular waste air duct.It is favourable that the transitional region that air admission hole enters annular waste air duct is placed in this terminal area of annular waste air duct, and therefore has with the big as far as possible distance from the air flow of minor air cell.
In addition, advantageously, there is not other impurity to be input to annular waste air duct basically by air admission hole.This preferably reaches like this, is connected to unlimited, surrounding air than clean environment in the zone that enters of a locational air admission hole of air nozzle device.Especially the zone that enters of air admission hole can not be directly towards drafting system.Also advantageously, covering device or a pipe are set on air admission hole promptly, prevent to suck flyings.
Another particularly advantageous technical scheme of invention is to be provided with like this, and air admission hole inserts annular waste air duct in a plane that is substantially perpendicular to resultant yarn.This air admission hole can be easy to make the dead band in the zone that also can play the connecting hole dorsad that excludes annular waste air duct on the air nozzle device.
Air admission hole is basically perpendicular to the such advantage of being mounted with of resultant yarn, and promptly air admission hole stretches out from this position of air nozzle device, and inhaled air is impure hardly at this place.Here, the zone that enters of air admission hole is enough away from this main usually drafting system that produces flyings.The purpose of air admission hole is, carries extra clean air in annular waste air duct, transports and prevent deposition with what improve the spinning speed air flow of being discharged by the minor air cell at this place and improve impurity.
For this reason advantageously, air admission hole is that tangent line is linked into annular waste air duct substantially.The spinning air that flows out of circling round from the minor air cell like this is supported it circles round, avoids air-flow to circle round simultaneously and too fastly stops and avoiding impurity generation sedimentation entrained in the air-flow.If being placed in a connecting hole of the low pressure source on the annular waste air duct is that tangential direction is stretched out in annular waste air duct substantially, this effect is just further strengthened.Therefore, unlikely the swerving of impurity that air-flow and Qi Nei are contained, but can flow into low pressure source from its circumnutation by connecting hole more swimmingly.Particularly advantageous is that air admission hole stands facing each other basically and is placed on the annular waste air duct in the connecting hole of a low pressure source.
The advantage of a technical scheme of the present invention is that the unlimited cross section of air admission hole is adjustable.For this reason, can settle a throttling arrangement in the zone that enters of air admission hole, such as a gate or similarity piece.Also advantageously, throttling arrangement connects mutually with a self-checking device, and the latter is connected with a control device again and the cross section that air admission hole opens wide is regulated or controlled to this control device according to other parameters on the air nozzle device.
Other advantages and the feature of invention can be learnt from following several embodiment.
Description of drawings
The generalized section of the amplification of an air nozzle device of Fig. 1.
Fig. 2 a and 2b are according to view along the various inlet hole that the II-II tangent plane cuts among Fig. 1.
The specific embodiment
Device shown in Figure 1 is to produce resultant yarns 1. these devices with ribbon 2 to contain a drafting system 3 and an air nozzle device 4 as basic module.
A not shown winding device is drawn and be transported to the ribbon 2 that spins by feeding direction A input drafting system 3 and as resultant yarn 1 by drawing direction B.
Only the drafting system 3 shown in the part can be designed to three rollers or drafting device with four rollers, and it contains many to roller, and the every pair of roller has a driven bottom roll and one be designed to the to pressurize top roller of roller.Roller to 5,6 as we all know mode dispose the guiding belt 7 and 8, may also have a pair of in its front here or two pairs of unshowned rollers.A pair of feeding roller 9,10 is settled in the exit of drafting system 3.Driven bottom roll is figure grade 5 and 9 signs respectively, and affiliated pressurization roller indicates with 6 and 10.Ribbon 2 is drawing to the requirement fiber number by well-known mode in drafting system 3.The thin drawing-off still fiber strip 11 of no twist is connected with drafting system 3.Fiber strip 11 is transported to drafting system 3 and links in the air nozzle device of settling 4.Truly as shown in the figure whether fiber strip 11 produce and do not produce by a drafting system 3, and this is not main to the present invention.Also can design other possibilities and produce this fiber strip 11.
Be mounted with a seamed edge as a fibre guide face of resistance twist in minor air cell's 13 scopes, this seamed edge is eccentric in a little and draws yarn channel 14 and be placed in the air admission hole scope of drawing yarn channel.Should be noted that at this compressed-air atomizer in 3 zones, minor air cell can be different from schematic structure fully.The thing of invention essence is an annular waste air duct 16.
The fiber that will spin in device is included on the one hand in the fiber strip 11 and by sending into with feeding passage 12 basic no twist and draws in the yarn channel 14.On the other hand, fiber is at feeding passage 12 and draw in the zone between the yarn channel 14 and be subjected to the effect of eddy current air-flow, thus fiber or at least the feeding hole of being drawn yarn channel 14, its terminal area radially drain.Thus, the yarn 1 of Sheng Chaning shows substantially by the fiber or the zone of fiber yarn core of yarn longitudinal extension as stated above, and it does not have the tangible twist, and to show fiber or zone of fiber be perimeter round the yarn core rotation within it.
This fibre structure can be realized according to an example model explanation, the head end of fiber, especially this fiber, still sail against the current and remain on the interior fiber of feeding passage in the zone of its servo-actuated, actual directly arrival of its head end drawn yarn channel 14, but the zone of fiber of servo-actuated, particularly fiber are when entering of feeding passage 12 no longer is held in the zone, extracted from fiber strip 11 by eddy current, then round resultant yarn 1 rotation.Under any circumstance, fiber is to be connected at one time in the yarn 1 of formation and by drawing yarn channel 14 to draw, and is again to be in the eddy current, and this eddy current makes fiber quicken to drain from the feeding hole of drawing yarn channel 14 eccentrically and discharges in annular waste air duct 16.The zone of fiber of drawing from fiber strip 11 by eddy current has constituted one and has been linked into the fiber eddy current that draws yarn channel 14 feeding holes, and its longer portion of external is introduced in the feeding hole of drawing yarn channel 14 round the air-flow power that spindle shape assembly 17 rotates and heads in the annular waste air duct 16.
This device allows extra high spinning speed, and its quantity can reach 600m/min.Here also can occur loosening out from fiber strip 11 single fiber, fiber broken end or other impurity and they are inhaled in the annular waste air duct 16.13 cross sections towards the annular waste air duct 16 of connecting hole 18 expansion of low pressure source 19 produce the air draught speed of corresponding reduction from the minor air cell.Because reduce air velocity, the translocation of air weakens, make the fine fibre or the impurity deposition of in passage, transporting.Particularly connecting hole 18 back to zone 20 in, be easy to produce this deposition.Deposit is to enlarge along with time remaining, and full annular exhaust passage 16 or connecting hole 18 are closed up to certain the time, and follow-up spinning process no longer may.Above the feeding roller that is configured in drafting system 3 of described prior art on 9,10 and be linked into cleaning passage in the annular waste air duct 16, make the air nozzle device 4 that causes because of obstruction job failure since feeding roller 9,10 flyings that suck are aggravated.
Air flow in the annular waste air duct 16 mainly is 13 to enter connecting hole 18 and and then enter low pressure source 19. because the shape of the annular waste air duct 16 that design reasons is predesignated from the minor air cell, particularly dead band of formation in the terminal area 29 of the minor air cell dorsad 13 of annular waste air duct 16.In this dead band, air velocity is very slow, therefore is very easy to produce deposition.
Therefore an air admission hole 21 should be set at least in air nozzle device 4, it inserts terminal area 29 arrangements of annular waste air duct 16. air admission holes 21 as close as possible annular waste air duct 16 in the zone 20 of connecting hole 18 dorsad.Like this, the air flow that enters by air admission hole 21 is with the 13 spinning air that flow into connecting holes 18 have big as far as possible distance and reach big as far as possible effect thus and prevent dead band in the annular waste air duct 16 from the minor air cell.
Advantageously, the unlimited cross section of air admission hole 21 is to regulate.For example can give air admission hole 21 configurations a throttling arrangement 23, can change the leaked-in air amount by this device.Throttling arrangement 23 can be designed as a gate that moves by the direction of arrow among the figure, is arranged to entering in the zone 22 of air admission hole 21.In addition, can also make such layout, promptly throttling arrangement 23 can be gone up unshowned mode by figure, adjusts or controls by a control device of air nozzle spinning device.
If the surrounding air severe contamination, entering of air admission hole 21 preferably adds division board or the similar device of settling one to indicate with figure grade 25 again in the zone 22.Under the situation of this high pollution, also can preferred another kind of method, promptly a pipe that dots 26 is connected to air admission hole, and the air of this pipe suction is from free of contamination zone at a distance.Another preferred example is, settle by central authorities, among the figure not a filter of expression the air inlet of cleaning is provided and is transported to air nozzle device 4 by pipe 26.In order to improve air inflow, another different schemes is that a pipeline 26 is set again, and in spinning process, the air inlet of band minimal overpressure flow into annular waste air duct 16 by pipe 26 and air admission hole 21.
Below will be according to the favourable flexible program of describing two various inlet holes 21 and connecting hole 18 from the air nozzle device shown in Fig. 1 along Fig. 2 a shown in the section II-II and 2b.
In Fig. 2 a, air admission hole 21 is point-blank to be placed in respectively to be positioned at the both sides that annular waste air duct 16 other main shaft shape parts 17 stand facing each other mutually with the connecting hole 18 that is used for low pressure source 19.Be mounted with its advantage like this, by air admission hole 21 leaked-in airs equably with symmetrically round main shaft shape parts circulation, thereby prevention trifle in the world in full force and effect or flyings are deposited in the annular waste air duct 16.
Different schemes shown in Fig. 2 b and Fig. 2 a contrast, air admission hole 21 and connecting hole 18 are that the axis round resultant yarn 1 reverses layout.Air admission hole 21 is tangentially to enter in the annular waste air duct 16 basically.The connecting hole 18 of low pressure source 19 is that tangent line picks out from annular waste air duct 16 substantially.The effect that two holes 18 and such arrangement of 21 are played is, forms the air flow of rotation or exist rotary air minor air cell 13 in to flow still to remain in the exhaust passage 16 in annular waste air duct 16.This same feasible be only a hole in two holes 18 and 21 is settled by tangential, and another hole to be provided with shown in Fig. 2 a.If the rotary air stream that is present in the minor air cell also keeps revolution in annular waste air duct 16, then can prevent very effectively the influential deposition formation of air nozzle device spinning work.Particularly with connecting hole basically by tangentially picking out from annular waste air duct, can make air flow that violent direction does not take place 19 the distance from minor air cell 13 to low pressure source and change, thereby impurities and staple fibre no problem ground arrival low pressure source 19 in the air-flow.
In addition advantageously, connecting hole 18 relative main shaft shape parts 17 are oppositely arranged with air admission hole 21 basically, wherein especially among the embodiment according to Fig. 2 b, the transitional region 27 of the air admission hole 21 in the annular waste air duct 16 and the transitional region 28 of connecting hole 18 obviously are conclusive for this reason.
Can do such setting in a unshowned technical scheme, air admission hole 21 is not in a plane perpendicular to resultant yarn 1 yet, and tiltedly is linked into annular waste air duct 16 in this inclination from the drafting system dorsad 3 of air nozzle device 4.What can enlarge air admission hole 21 like this enters zone 22 distances to drafting system 3, thereby makes the air of suction contain still less impurity.The transitional region 27 of the air admission hole in the annular waste air duct 16 even can extend into the boundary face on the plane of annular waste air duct 16, i.e. the figure grade place of terminal area 29 among Fig. 1.In order to realize entering zone 22 and the big as far as possible distance of drafting system 3, under extreme case even can do this preferred, be that air admission hole 21 is parallel to and draws yarn channel 14 setting, thereby make actual being in reverse to of additional air draw yarn direction B, standing facing each other in this side inflow annular waste air duct 16 of connecting hole 18.
Another is favourable, unshowned technical scheme is that two or more air admission holes 21 are arranged on the circumference of annular waste air duct 16 on the figure.Can improve the air capacity of input like this and further improve flow behavior.
