Description
The present invention relates to a kind of jet textile apparatus, this device is used for from through the intrafascicular production of the staple fibre of minor air cell spinning, at least one compressed air channel with the outlet of nozzle shape feeds in the described minor air cell, described compressed air channel be designed to be arranged in the nozzle body, be arranged in the nozzle slot that becomes a plane radially with the traffic direction of staple fibre bundle, described nozzle slot is finished described compressed air channel by the end face of a lid.
Such jet textile apparatus is the prior art of Deutsche Bundespatent 37 32 708 A1.Position about compressed air channel in the document discloses two kinds of flexible programs.In described a kind of flexible program, in becoming radially plane, the traffic direction with the staple fibre bundle has a plurality of compressed air channels, and in the preamble of present patent application, be starting point wherein with described scheme.So the compressed air that arrives on the staple fibre bundle must turn to suddenly, wherein more or less let nature take its course, no matter air-flow flows on traffic direction or in the opposite direction.In described another program, be positioned at the cone surface and, compressed air channel tilted at the traffic direction of staple fibre bundle by the described nozzle slot of cone surface coverage of being attached troops to a unit by nozzle slot.In this case, there is the danger of sealing deficiency, because there is tolerance in the cone surface of attaching troops to a unit mutually always.
Usually under the situation that is not similar jet textile apparatus, compressed air channel is holed.Compare with this embodiment, above-mentioned jet textile apparatus has the advantage of the manufacturing of being very easy to, because can be in a nozzle body in very easy mode, make high-precision nozzle slot by milling, next described nozzle slot is covered by equipment surface, and finishes whole compressed air channel thus.Because this compressed air channel exposes before assembling, thus can be in simple mode, detect with regard to its precision, and carry out back processing where necessary.When carrying out described detection, also can choose the segmentation that contains error, still, the manufacturing of this nozzle slot is not limited to milling, also can for example be undertaken by a punching course.
Task of the present invention is, is that jet textile apparatus is made the desired compression air duct on the basis of prior art as previously mentioned, and considers that simultaneously when having excellent sealing, the component of an air-flow is also wanted the traffic direction of aligned fibers bundle.
Solve this task by following manner, promptly lid has an inclination air deflection surface that tilts at the traffic direction of staple fibre bundle being right after described exit.
Because the nozzle slot that extends from a sagittal plane with respect to the traffic direction of staple fibre bundle, the surface of the nozzle body of the end face of lid and this end face of attaching troops to a unit can be respectively a plane, makes not have sealing problem.In addition, assurance deflects on the traffic direction of staple fibre bundle the compressed air in the junction of the outlet of described at least one compressed air channel, makes clear and definite flowing relation takes place.
Compressed air channel is preferably used for jet textile apparatus designed according to this invention, and described device for example designs according to EP 12 17 109 A2.
The air deflection surface advantageously is designed to the conical anchor ring around the staple fibre bundle.In this manner, can especially easily make the air deflection surface.To this, a plurality of outlets and described anchor ring are tangent to be favourable.This has not only obtained the good twist configuration of company of spinning, but also has the advantage that prolongs deflection path for compressed air, because this compressed air is at first aimed at the air deflection surface by the component in the tangential direction of anchor ring.
Anchor ring itself can be put down and be narrow very much.Therefore can see that if the tapering of anchor ring is between 10 ° to 20 ° with respect to the sagittal plane, this is enough so.Can see also that in addition the length on air deflection surface can be in the order of magnitude of the width of nozzle slot.
Other advantages of the present invention and feature draw from the following description of embodiment.
Fig. 1 illustrates axial cross section according to jet textile apparatus of the present invention with about ten times enlarged drawing.
Fig. 2 is with little with respect to Fig. 1, and the view big with respect to original size illustrates along the cross section of the nozzle body of cross section II-II among Fig. 1.
Fig. 3 is to illustrate according to the view of lid of the present invention on the direction of the arrow III of Fig. 1 with the corresponding dimension scale of Fig. 2.
Fig. 4 illustrates along the cross section of the lid of the cross section IV-IV of Fig. 3.
Fig. 1 illustrates a jet textile apparatus, utilizes described device to make the loose staple fibre bundle of carrying by input channel 12 carry out twist configuration in minor air cell 3, makes to produce spinning 4 that described spinning is discharged by yarn output channel 5.This staple fibre bundle 2 can be from other draft apparatus of a drafting system or.Hydraulic mechanism produces eddy current by compressed air tangentially being blown over the compressed air channel 6 that feeds in this minor air cell 3 in described minor air cell 3.Discharge by outlet passageway 8 from the compressed air that the outlet 7 of compressed air channel 6 is overflowed, wherein said outlet passageway has a ring section of arranging around yarn output channel 5 around spindle shape, static member 9.
The limit 11 that is furnished with fiber guide surface 12 after the outlet 10 of input channel 1 is as twisted retaining mechanism (Drallsperre), described limit 11 and yarn output channel 5 in the scope of its input port 13, arrange decentraction.
In described jet textile apparatus, need the fiber of spinning to be present in the staple fibre bundle 2 on the one hand, and be not incorporated into the yarn output channel 5 with having twist configuration basically from the outlet 10 of input channel 1.And on the other hand in the scope between input channel 1 and yarn output channel 5, fiber is subjected to the effect of eddy current, by this effect make fiber or at least the bottom part of fiber radially break away from the input port 13 of yarn output channel 5.So the yarn 4 that utilizes described method to make also illustrates basically the fiber that distributes along the yarn length direction or do not have a heart yarn of twisted pars fibrosa and the part of an outside substantially, and is twisted around described heart yarn at fiber described in this part or pars fibrosa.
According to a kind of desirable explanation, this yarn formation method realizes like this: promptly the front end of fiber, especially its rear end part still keep the mobile fiber front end of forward direction in input channel 1, basically directly arrive yarn output channel 5, if but especially the rear end pars fibrosa no longer remains in the inlet scope of input channel 1, they form by eddy current and are drawn out of from staple fibre bundle 2 so, and carry out twisted around the yarn 4 that produces then.
In any case, fiber not only inweaves the yarn 4 of generation at synchronization, and fiber is discharged by yarn output channel 5 thus, and is subjected to eddy current effect, the centrifugal fiber that makes of described eddy current quickens (promptly departing from the input port 13 of yarn output channel 5), and fiber is discharged in the outlet passageway 8.The pars fibrosa of extracting out from staple fibre bundle 2 by eddy current forms a fiber eddy current that feeds the input port 13 of yarn output channel 5, be wrapped in to the longer part spirality of this fiber eddy current the outside of the member 9 of spindle shape, and in this conveyor screw, pull to the input port 13 of yarn output channel 5 on the contrary with the power of the air-flow of outlet passageway 8.
By means of replenishing Fig. 2,3,4 that Fig. 1 quotes again, below compressed air channel 6 is further described.
According to the embodiment shown in the described figure, each jet textile apparatus has four compressed air channels 6, and described compressed air channel is equipped with outlet 7 respectively, and as being clearly shown that among Fig. 2, tangentially guides in the minor air cell 3.According to Fig. 1 and 2, these compressed air channels 6 are processed into nozzle slot 15 in nozzle body 14, and finish compressed air channel 6 according to Fig. 1,3 and 4 by the end face 16 of lid 17.Nozzle slot 15 is distributed among the sagittal plane E of traffic direction A of staple fibre bundle 2, to this referring to Fig. 1.
Radially the annular space 18 around this nozzle body 14 is connected with compressed air source in the mode that does not illustrate.By axial groove 19 that process, nozzle body 14 in the profile externally, so compressed air arrives single compressed air channel 6 from annular space 18.Annular space 18 outwards is closed by the wall of shell 20.
According to the present invention, lid 17 has the inclination air deflection surface 21 that the traffic direction A of a relative staple fibre bundle 2 tilts being right after outlet 7 places.Even nozzle slot 15 also is arranged in sagittal plane E by it and can be implemented easily, yet is directed on the traffic direction A of fibre bundle 2 by air deflection surface 21 from exporting 7 compressed air that come out.As can be seen, constitute conical anchor ring 22 on this air deflection surface 21, described anchor ring is around described staple fibre bundle 2, and tangent with a plurality of outlet 7.
