Description
Technical field
The present invention relates to a kind of nonwoven guiding device that is used on the textile machine that has drafting system, this device is used for fibroreticulate compressing, fiber web is swelling state when leaving described drafting system, described device has an import and an outlet subsequently, and the area of section of outlet is less than the entrance section area.Simultaneously, the invention still further relates to a kind of textile machine that has described nonwoven guiding device.
Background technology
Above-mentioned guider in carding machine, drawing frame and combing machine be for people known.For example, the RSB-D35 drawing frame of known Lv Te (Rieter) company has a rectangular head of the trumpet away from the inlet certain distance that extends on fibroreticulate width.This head of the trumpet has one and falls in, aduncate striking face, and the minimum point of head of the trumpet forms pipe, and the size of pipe narrows down to into the conduit of a minor diameter.This silver funnel often is made to netted head of the trumpet (web funnel).The fiber web guiding outlet that is designed to elongate can be tucked in the described rectangular head of the trumpet, and as this terminal, and fiber web passes outlet within it.At this place, the guiding outlet conveying non-textile fiber net of described non-textile fiber net arrives belt head of the trumpet subsequently.The belt head of the trumpet leaves the gap at its outlet end between the calender roll of paired tail tail continuous (end-placed), thus, nonwoven fiber band is compacted between them, is pulled out the belt head of the trumpet simultaneously.
A shortcoming of this known structure is: on the fiber web cross section, the more fiber that is positioned on the fiber web cross section can not be introduced directly into fiber web guiding outlet after leaving drafting system.More disadvantageously: these disposable fibre high-speeds of going out impinge upon on the striking face of rectangular head of the trumpet, are curled, and then, depart from described guider.This unexpected bump has at first been upset the fiber web of the accurate drawing-off of previous quilt, secondly, hindered the fiber of the described outside in the fiber web, making has a sizable gap in those more back that is positioned at inner fiber, is positioned at inner fiber and is delivered directly to described fiber web outlet.Use this device, in a kind of very unwelcome mode, the fiber in the fiber web runs foul of each other once more.The result is that the depth of parallelism of fiber is destroyed, especially in noil.
Summary of the invention
Therefore, the purpose of this invention is to provide a kind of nonwoven guiding device, the said apparatus in open channel can be protected from the fiber web of drafting system output and be sent to stretching device (for example, calender roll), and the band resistance does not take place in fiber web as much as possible.
The object of the invention can the sort ofly have at least the nonwoven guiding device of a guide pass to realize between the entrance point and the port of export by what begin to mention, and design can make the fiber that is positioned at inside, fiber web cross section can not be delivered directly to the port of export like that to being positioned at outside fiber like this.With the corresponding textile machine of the present invention, be characterised in that the function that has nonwoven guiding device by this way.
Nonwoven guiding device of the present invention also has outstanding feature, and the fiber of fiber web outside is directed to the port of export along a more direct passage, that is, the degree that deflects than the fiber that is positioned at inside is little.Thus, all fibres quilt in the fiber web especially is positioned at the fiber of fiber web inside by at least one guide pass exit end, although transmitted along the most direct path, also can suitably be led.Therefore, the fiber that is positioned at fiber web inside do not pass from the outlet roller of drafting system promptly one turn to the upper strata roller to the port of export and the beeline that enters outlet of fiber web guide or banded head of the trumpet.
Generally speaking, accordingly, the segment distance that those fibers that are positioned at fiber web inside pass through is manually extended, drafting system send and calender roll between fiber web in the degree of deflection of fiber can be held minimum, perhaps, even fully eliminate.Accordingly, meaningfully, be positioned at outside fiber in guiding on the passage of an intimate straight line or in an arc a little curve and arrive the port of export, and the center fiber that is positioned at zone line arrives the port of export along a delay, long arcuate channel.
By the present invention, at first, in the outlet of drafting system, fiber web has good stretching quality, and secondly, when they left described drafting system, being arranged in parallel of fiber remained intact.In general, the present invention can impel the formation of fiber band more even than prior art.
Consistent with the advantage of embodiment, at least one guide pass is designed to be up to the port of export from the outlet of drafting system, and the single distance that all fibers pass through is basic identical, so that fiber can not upset after leaving drafting system.In order to satisfy this condition, need set up Mathematical Modeling.The result shows that suitable shape is that guide pass has a curved shape inner similar to shell, to satisfy the requirement that waits the stroke spacing.Advantageously, with during the outlet roller of drafting system is connected, receive guide pass and extend to consistent with fibroreticulate width.Consistent with the rotating part that guide pass may have, enter into the direction of calender roll in order to guide fiber web from the outlet of drafting system, the side of guide pass must be accurately towards the port of export.In contrast, the corresponding surface portion that is used for the fiber of fiber web inside is designed to bending more, and a bigger incurvature is promptly arranged, wherein, the fiber in the middle of inner most outline line is preserved for, that is, those are positioned at the fiber in the middle of the fiber web cross section.
Advantageously, nonwoven guiding device by or can directly be placed in the back of final drafting system roller, promptly final drafting system roller is right.In this way, after leaving drafting system, can implement directly guiding control to fiber.
If at least one guide pass is designed to continuous substantially, that is, between the entrance point and the port of export, form continuous surface, just might set up the continuous guiding of fiber.
In entrance area, be directed into intimate tangential guide pass as fruit fiber, consistent with it then with respect to fibroreticulate width layout, be sent to the port of export, can find that shielded fiber guide can be enhanced.Therefore, can avoid the accurate fiber web generation of the good drawing-off of order disturbance.
In known drafting system, the difference between two embodiment can be distinguished.In first embodiment, when leaving drafting system, the axle oblique arrangement of the belt loading head of the relative back of fiber web device.For example, if drafting system is arranged to level or inclination, banded head of the trumpet just is designed to vertically.In the drafting system of this form, guide pass among at least one the present invention is preferentially designed in such a way: can obtain corresponding passage curvature, can avoid the fiber on the web width unordered to small part, or, in particularly preferred embodiment, can avoid fully.
The possibility of second kind of embodiment is, drafting system itself is by arranged vertical, and in the drafting system of this traditional type, fiber web can not depart from fiber web plane (with respect to the direct export of drafting system) substantially, and operation downwards enters banded head of the trumpet.In this arrangement, the guide pass among at least one the present invention also can be used to the suitable task of partly avoiding the fiber disturbance that increased basically.
With a kind of preferred mode, fiber can move between at least two guide pass, and these two guide pass can be settled in opposition to each otherly or be placed in successively on the direction of fiber web operation.In an embodiment who combines with these examples of implementation, a fibroreticulate at least part subsequently can be along another guide pass operation on a guide pass.For example, in the drafting system of the vertical design of above-mentioned appointment, especially the fiber of fiber web inside is guided the profile through a guide pass, departs from the passage that to lead to banded head of the trumpet, up to just being guided once more along their original passages by the guide pass that is positioned at the downstream.
A kind of with traditional opposite arrangement of vertical drafting system, it tilts promptly a kind of horizontal drafting system with respect to the axle of vertical banded head of the trumpet, design and installation guide pass easily, wherein, under transfer rate faster, inner most at least fiber is guided along the spill guide pass substantially; Under slower transfer rate, be guided along the convex guide rail face substantially.Under the described situation of transfer rate faster, for example, greater than 300m/min, internal fiber is guided along concave surface when leaving drafting system then.Than jogging speed the time, for example, 300m/min, internal fiber can not departed from these spill guide pass, but are moved toward the fiber web outlet in a more direct path.For this reason, advantageously, when described slower transfer rate, can not make fiber deflection opposite side.For this situation, internal fiber is by the guide pass guiding along projection, and is consistent with the present invention, arrives the port of export in this way.
Consistent with more excellent embodiment, the port of export, arrival end be the same with at least one guide pass to be configured to complete parts.If not only guide pass is arranged, also can be designed to a plurality of parts.In this case, the single parts of nonwoven guiding device, for example, and can be separate, make that for example, the insertion process again of the terminal fiber of fiber web becomes easier.
Consistent with a more excellent embodiment, at least one guide pass can in position be changed.In this way, when low transmission speed, can make the guide pass of fiber web by described projection, when fair speed occurring, the guide pass of projection just can be removed along axis.This measure can help avoid the formation of air turbulence, perhaps the fibrous material tamponade device.If the described position change by at least one guide pass can temporarily enlarge the cross section that is used for inserting again, so also can make the insertion again of fiber ends become easier.
Advantageously, a kind of like this position changes and can realize by slew gear.In addition, provide a kind of control device with a kind of favourable mode, this control device is controlled by transfer rate, and instruction is sent in the specific position control of guide pass.
Selectable or addible is that the pivot form also can be selected or be designed in addition to nonwoven guiding device.Swaying can be all or only to be that part is left.This also can occur in the situation of band resistance and/or in place that one of outlet roller is located to twine.Described swaying also helps to strengthen accessibility to the downstream components that is arranged in a straight line with nonwoven guiding device, for example, and fiber web outlet device or banded head of the trumpet, or the purpose that in maintenance breaks manipulate control procedure, is used for inserting again.
In addition, can have the opening that is used to discharge or import air.For example, these openings can be very little, and link to each other with air exhauster, to guarantee embedding even along the fiber of guide pass.In addition, also can make fiber on the direction of the port of export, have a motion combination by opening.Also can be a given part, the passage that opening is entered as air perhaps is used for deaeration at other part construction opening again.In nonwoven guiding device, opening can also be as the formation that hinders air turbulence.
Advantageously, nonwoven guiding device holds fiber, holds area (area-wise) at least greater than 180 degree, in a further advantageous embodiment, can be full encirclement.Especially in the port of export fiber web outlet device or the transmission district of next-door neighbour's banded head of the trumpet finally, advantageously, nonwoven guiding device is placed around the fiber web that strikes up partnership substantially.
Nonwoven guiding device of the present invention is more excellent as to be designed to tubaeformly, promptly builds around a flaring object.Guiding in flared structure and the open channel is described consistent, and has such purpose, and when fiber web left drafting system, fiber web was compacted, and is identical with reality, and is drawn towards the fiber web outlet device and/or the banded head of the trumpet of back.Being used for this suitable delivery channel of drawing function can link together with the banded head of the trumpet of back and become an one part.This connection, identical with another preferred embodiment, can be combined in the nonwoven guiding device of the present invention.
Advantageously, at least one guide pass does not have fiber to wear, and evenly noiseless in order to ensure what operate promptly in order to avoid departing from the accumulation of fiber, at least one guide pass is designed to does not have friction as much as possible yet.For this reason, the preferred construction material has low frictional properties matter, for example, and the guide pass that has enamel coating or make by the stainless steel of polishing.Suitable structural material does not preferably have friction and does not have chip.
In addition, the present invention includes the textile machine that has drafting system, it comprises a nonwoven guiding device as hereinbefore.Based on the guiding of the fiber on the basis of the present invention, can save one and turn to the upper strata roller, although all comprise these rollers in most of common drawing-off machinery.Fibroreticulate rotation for example, changes direction, according to the present invention, can be born by at least one guide pass fully.
The favourable improvement of the present invention embodies in the dependent claims.

The specific embodiment
Shown in Figure 1 is the generalized section that has the right horizontal drafting system of interconnected roller.The inlet roller is made up of an inlet lower roll 2 and an inlet top roll 5, and and then Zhong Jian roller is to lower roll 3 in the middle of comprising and a middle top roll 6.These two rollers are to forming so-called preliminary draft district, and what connect later is main drawing area, main drawing area comprises be described intermediate calender rolls to right with outlet roller, outlet roller is to comprising that sending lower roll 4 and one for one sends top roll 7.Main drawing area is placed the tube connector 8 of a hollow, does not have the airborne fiber of being suspended in of combination in the main drawing area with removing.Fiber drafted in drafting system 1 is represented with alphabetical V.Introduce letter b in the drafting system 1 and represent one or more fibre bundle.Drafting system can be the part of carding machine, drawing frame or combing machine.Whether the present invention and drafting system 1 be by control is irrelevant automatically.In the back of drafting system 1 is nonwoven guiding device 20 of the present invention, and corresponding to first embodiment, shown in Figure 2 is its perspective view.This nonwoven guiding device 20 is made of two parts, and first is a head of the trumpet 21, and second portion is a spherical bent bodies 31, and described spherical bent bodies is similar in the centre extends in head of the trumpet 21.Head of the trumpet 21, it is more accurate to describe ground in Fig. 3-5, is designed to towards drafting system 1 opening, and has rising edge 27a in both sides, is connected with the marginal portion 27b on top, and 27b is straight line substantially.On lower side, head of the trumpet 21 has a groove 27c, and passing this groove is an arc bracing frame 35 that is used for described bent bodies 31.In general, make head of the trumpet 21 seem very compact, head of the trumpet 21 has a wide entrance point 22, is used to receive the fiber web V that is discharged by drafting system 1.Another end of head of the trumpet 21 is the port of export 24, in an embodiment shown in, sealing around this port of export is designed to, and cross section with a circle.Also can select other cross sectional shape, for example, ellipse.
Specifically shown in the profile of Fig. 5, from the left side of figure, the rear wall of head of the trumpet 21 is designed to towards the port of export 24 indents.
Rear wall also can be vertical or inwardly outstanding (projection), at the port of export 24, may reduce turbulent flow, in addition, also can cause winding in fiber web.
If fiber web is discharged from drafting system 1 with higher relatively speed, for this reason, fiber web is sent to guide pass 23, and the aforementioned operation method is suitable for too.In this case, fiber web at first passes head of the trumpet 21, and substantially parallel with the guide pass in entrance point 22 zones, is inducted into the port of export 24 reposefully then.When transfer rate was slow, the speed motive force that is endowed fiber web V was not enough to promote fiber web V to guide pass 23 operations.In this case, fiber web arrives the port of export 24 along guide pass 33 (seeing the dotted line among Fig. 1) slippage of the projection of the bent bodies 31 that is oppositely arranged more.
The foot that is used for the bracing frame 35 of spherical bent bodies 31 has a slit 36 to be used for the construction bolt (not shown), and by this slit, bent bodies 31 can be regulated with respect to the position of loudspeaker 21 and (be seen the double-head arrow f among Fig. 1
1).When fiber web V was no longer supported by guide pass 33, in loudspeaker 21, adjustable depth of engagement of bent bodies 31 limited at once.
In addition, as shown in Figure 2, below the port of export 24, loudspeaker 21 are supported by a pin of widening 25, and the supported underneath of pin is on a dish 9.Do not provide the fastening bolt that is used for this connection among the figure.Side flange 10 is equipped with, the bottom of side flange 10 fluted 11 in both sides at dish 9.These grooves 11 can be respectively be connected with fixedly wheel shaft on the lower support frame, make dish 9 to pivot, and this takes place to be with when hindering very important nonwoven guiding device 20 in.The direction that pivots is by the double-head arrow f among Fig. 1 and 2
2Expression.
Below the pin 25 of head of the trumpet 21 is four exhaust passages 26.These passages 26 are positioned on four horizontal directions, lead to the outside, help the release of air in the fiber web compression process.Arrow f is used in described exhaust passage in Fig. 1-3
3Expression.On the direction of its operation, fiber web continues to be under the pressure of increase, and the air from fiber web comes out also can discharge by the perforate 26a (Fig. 1) between groove 27c and bracing frame 35.(also can be referring to the arrow f among Fig. 1,2
4) below dish 9, be a fiber web outlet 12 that is connected with the port of export 24, the fiber web V that its guiding combines arrives banded head of the trumpet (not shown).
Among Fig. 6, opposite be that it is downward-sloping to carry fibroreticulate drafting system 1 with horizontally disposed.Aspect further feature, this layout is all similar to the drafting system of Fig. 1.A situation of this structure be nonwoven guiding device 120 have with Fig. 1-5 in different geometries.The perspective view of Fig. 7 has been described the head of the trumpet 121 as an assembly of nonwoven guiding device 120 more exactly.Head of the trumpet 21 among these loudspeaker 121 image pattern 1-5 is projection equally, but size dwindle, and its structure is duplicate substantially.Arrival end 122 extends beyond fibroreticulate width, and the both sides approximately linear is tapered towards the port of export 124 downwards.And, downward from the middle part, the contour increase of the concavity of guide pass 123.In Fig. 6, also have the plug-in unit 131 of a flat warp architecture, thrust head of the trumpet 121, be used for guiding (for example, less than 300m/min) with the fiber of slow transfer rate motion.When described plug-in unit 131 did not exist, head of the trumpet 121 was unique executive components of nonwoven guiding device 120.
What be positioned at nonwoven guiding device 120 rear portions is fiber web conduit 12, is connected to banded head of the trumpet 14.In addition, at side, downward-sloping towards the centre of banded head of the trumpet is perforate 13, and by perforate 13, air can overflow from fiber web V in the process of fiber web compression.Also there is the possibility of other release gas to exist, for example, the inlet of described conduit 12 and be located immediately at the inlet of the upstream of nonwoven guiding device 120.These all indicate with arrow.In banded head of the trumpet 14, (also can before this) also can provide other perforate (not providing) in a kind of known mode herein, is used to supply with compressed air and gives fiber web the motive force on downstream direction.This measure Muller's fibers net end reenters operation in reentering process.Among Fig. 6, the rear portion of banded head of the trumpet 14 is connected to a pair of calender roll 15,16, this calender roll carries out drawing-off in a kind of known mode to the fiber web V that passes nonwoven guiding device 120, also is used for the lasting transmission of finished product band to trough of belt, and is ultimately delivered to the bar tube that is used to adorn spinning material.
The head of the trumpet 121 of sealing around Fig. 7 has provided in detail, on guide pass 123, the direction that flows along fiber web marks dotted line 128.These lines 128 are equal in length basically, and this shows that on fibroreticulate whole width, the length of passage is equal substantially, and irrelevant with the dotted line position.
Head of the trumpet 121 as shown in Figure 8 (the 3rd embodiment), embodiment also can be easy to change, and what Fig. 8 provided is the head of the trumpet that does not have sealing all around, and perforate 129 is arranged on guide pass 123.Moreover, identical with the air relief passageway 26 of first embodiment, be used for discharging air by coming out from the fiber web compression.Alternatively, according to the needs of using, compressed air also can be injected into by these described perforates, helps the insertion process again of fiber web end.
Fig. 9 and 10 is the 4th embodiment of nonwoven guiding device of the present invention.Under the situation that drafting system stands vertically, good especially operation, Fig. 9 has mainly provided outlet roller to 4,7.Nonwoven guiding device 220 here clearly, is directly followed at described roller 4,7 back, and in this case, described device 220 is designed to have only a member, and on the fiber web travel direction, has the conical in shape of the slight convergent of elongation.What match is an entrance point that is broadened 222 to 4,7 for nonwoven guiding device 220 and roller, so that fiber web V can be accepted on the overall width of entrance point.At another end is the cross section of round exit end 224, similar to the design of Fig. 6, and fiber web outlet connecting pipe 12 is followed in the back, banded head of the trumpet 14 and calender roll 15,16.
From the perspective view of Fig. 9 and Figure 10 vertically and center section plan as can be seen, nonwoven guiding device is a guide pass 233 on vertical wall, this guide pass is crooked in fluid, can make the fiber of fiber web inside leave (seeing the dotted line Figure 10) from its vertical channel, along this guide pass, the fiber that is positioned at fiber web V inside does not have the operation of disturbance ground.Wai Bu fiber, the degree that departs from from the fiber web plane is more little.Do not have direction to rotate on the outside fiber wall over there, be directed to the port of export 224 (seeing the dotted line among Figure 10) linearly but be close to.Can be in the inside of nonwoven guiding device 220 near fibroreticulate zone, represent (with identical in Figure 11 and 12) at Fig. 9 with dotted line in 10.
From the profile of Figure 10 as can be seen, offside in the fiber of fiber web inside, below the discharge port of roller 4,7, expand immediately, by guiding rail face at first.In connection subsequently, these fibers are shifted to the wall on opposite immediately, and this wall is designed to guide pass once more, so that fiber can arrive the port of export 224.Even in this embodiment, more excellent is, the path of measuring fiber 224 processes from entrance point 222 to the port of export in the fiber web V of various cross sectional shapes all equates.
In order to carry out inserting simply again of fiber web end, flaring nonwoven guiding device 220 can vertically be cut open an otch downwards on certain position.Must guarantee that fiber web does not enter this otch in running.Another selection that helps to insert again is that the wall part of dimension net guider 220 can be movable opening or can be removed.
Figure 11 and 12 is the 5th embodiment of fiber web device 320.Described device 320 is designed to two parts.Outwards protruding and turning to the guide pass 333 of median fiber is the part of object 331, and this guide pass bending in head of the trumpet 321 and extended, and advantageously, its position can be regulated.Advantageously, this moment, object 321 can (be seen double-head arrow f around axle 339 pivots
5).For the fiber web end of resetting, object 321 at first is diverted the outside, and described fiber web end is inserted in the head of the trumpet 321 deeply, the machine slow start.Insert under the case of successful, object 331 is rotated back into the running position from servo position again.
Head of the trumpet 321 has a guide pass 323 equally, and after fiber had departed from guide pass 333 from entrance point 322 to the port of export on 324 the direct path, guide pass 323 guiding median fibers in the end arrived the port of export 324 on the passage.Figure 12 shows nonwoven guiding device 320 with a kind of upset view that can better understand its feature.
Identical with the 6th embodiment of the present invention, in the embodiment shown in Figure 13 and 14, the design of nonwoven guiding device 420 is similar to Fig. 1-5.Difference is: the top 427b of head of the trumpet 421 is in alignment, and head of the trumpet 421 is discrete components of nonwoven guiding device 420.The direction that the port of export 422 imports guide pass 423 towards fiber web is wound into the semi-cylindrical shaped of minor radius, and guide pass 423 has little protruding contour.In order to reach effect of the present invention, described protuberance at fibroreticulate middle body than protruding more obviously at its edge.The port of export 424 basic one-tenth semi-circular cross-section, for this reason, the port of export forms an opening, simultaneously also easily near adjacent element.Side 427a is linear substantially to the port of export 424 from the entrance point 422 of bending.
Respectively there is a flange 428 in two outsides in the port of export 424 zones, and a pivot pin 429 is housed on this flange.Two pivot pin elements 428 are installed in rotation on the blocks 409, and can rotate around axle 411.This pivot can make head of the trumpet 421, and (Figure 13) forwards maintenance position (Figure 14) to from the running position, carries out the free-ended insertion of fiber web (seeing around the arrow of axle 411).Or even take place at outlet roller under the situation of band resistance or winding, head of the trumpet 421 is pivoted into described maintenance position from the running position, can easier enter to remove to disturb.
Can also further find out from Figure 13 and 14, the lower side 427c of head of the trumpet 421 is positioned on the blocks 409, and part is inserted this opening (not shown) around 430, one head of the trumpet of cratering opening, on the direction that fiber web is advanced, finally connect a banded head of the trumpet.
And the embodiment shown in Fig. 1-5 compares, and the ability of pivot is had any different, and mainly is that head of the trumpet 421 can be pivoted but the element of back can not pivot (for example, fiber web outlet device or banded head of the trumpet).
The common ground of all embodiment that provide among the figure is: the fiber among the fiber web V respectively with a kind of shielded mode be directed to they separately the port of export and can not swerve.In the entrance point of nonwoven guiding device in all embodiments, fiber all can clash into guide pass.In this case, the intimate tangential direction bump of fiber, for example, relative very little angle of guide pass.
