There is uncontrollable mutual collision in center above circular cone district and in cylindrical zone.Thus may cause ribbon produces
Thickening position also forms Z-fold fiber.This situation can adversely affect for the following process process of ribbon.Be singly because of
For having rotationally symmetrical and narrow and small entrance cross-section, above-mentioned hopper is just not suitable for fleece is compacted into ribbon.With fiber
In bar, the fiber already at compacted state is different, and loosely the fiber in fleece may uncontrollably, tangle confusedly
Together.Processed ribbon twisted the most undesirable.
File DE 196 18 642 A1 discloses the fleece hopper that a type is similar.
Summary of the invention
The task of the present invention is: a kind of fleece hopper of design, can pass through fleece hopper to guide at a high speed fleece whereby,
So that the ribbon from the output of fleece hopper realizes high-quality.
Above-mentioned task completes by possessing fleece hopper used by the compacting fleece of feature described in independent claims 1.
Propose to design a kind of fleece hopper (being mostly installed at drawing frame, carding machine or combing machine) for being compacted fleece,
This hopper is with elongated entrance side and outlet side, and the fleece of stretching, extension enters fleece hopper at entrance side, at outlet side fiber
Net again leaves fleece hopper as ribbon.It is designed with delivery outlet at outlet side.Ribbon after compacting by delivery outlet from
Fleece hopper exports.
Additionally, fleece hopper is also devised with at least one fleece spigot surface between entrance side and outlet side, in order to edge
Delivery outlet direction leads into the fleece of fleece hopper.The fleece entering hopper arrives spigot surface and produces along delivery outlet direction
Raw deflection.Fleece is compressed into ribbon by spigot surface.
Fleece hopper also between spigot surface and delivery outlet with step.By this step, from spigot surface along delivery outlet direction
The fleece portion of motion will obtain torque, and its action direction is perpendicular to web motion direction.See from web motion direction
Examine, define the eddy current starting from step scope and extending in delivery outlet.Fleece can be directed to delivery outlet more in an orderly manner
Direction.This eddy current especially can reduce the acceleration acting on fleece.By this eddy current, fleece is put down with 90 ° of angle of bends
Import in delivery outlet suitablely.Above-mentioned design measure can reduce thickening point in the case of fleece high-speed motion or Z-fold is fine
The quantity of dimension.The quality being compacted ribbon is improved.
According to the present invention, fleece hopper between step and delivery outlet with at least one median surface.Fiber from entrance side
Net to arrive median surface along subvertical direction.Fleece produces this collision in this range, causes and the single fibre of not all
Dimension all keeps parastate, and intersecting occurs in the most a part of single fiber.Which improves and arrange in this way
The degree that is connected with each other of single fiber, thus improve the band tack of ribbon.It is compacted ribbon and leaves fleece material
Enough band tacks have been possessed after bucket delivery outlet.The quality being compacted ribbon is improved.
The eddy current formed by step also moves past at least one median surface.The region that median surface can extend as eddy current camber line equally.
In addition following design is favourable: fleece hopper is consisted of the matrix of essentially rectangular shape, and matrix has x side
Lateral extension on longitudinal extension upwards and the y direction of size perpendicular to the longitudinally-extending, the two size is the most vertical
Web motion direction in design.Matrix also has the height along the z direction in web motion direction and extends size.Wherein
Longitudinal extension on x direction is more than the lateral extension on y direction.Therefore fleece hopper have elongate structure and from
And adapt with the flat pattern of fleece.The especially big manyfold of its thickness of the width ratio of fleece.Fleece hopper horizontal
Extension size is similarly less than its longitudinal extension and can meet requirement.This design simplifies assembly manipulation and can ensure that fleece material
Bucket accessibility in plant equipment.
Following design is especially beneficial: median surface uses domes.The fiber of fleece arrives median surface after step, and leads to
Cross domes and be directed to delivery outlet direction with protected form.This measure is for guaranteeing that single fiber is at fleece or fiber
Bar is in desired location and has the most excellent effect.
If it addition, fleece hopper will be favourable with two spigot surfaces spaced in x direction and/or step.Typically
In the case of, flat fleece is mainly compressed by fleece hopper on its width.It is to say, the single fiber of fleece
It is directed to fleece center in the x direction.Web thickness change is significantly less than its change width, i.e. single fiber in y direction
On only produce a small amount of mobile.So, fleece hopper is with two spigot surfaces the most spaced and/or step
Meet requirement.
Another kind of expedients is: spigot surface broadens in the z-direction, in particular by tie rod linkage.So can save material and
Alleviate weight.Because the eddy current produced by step is extended in the y-direction, this eddy current also be may be guided by the spigot surface widened.
The spigot surface that this design is possible to prevent eddy current to pass through to widen skids off from fleece hopper.
The face of being directed to is designed as plane and has the advantage that equally.The processing of smooth spigot surface is simple.Therefore, (such as) of smooth spigot surface
Milling process is time-consuming, thus has saved cost.
Additionally, following design is favourable: delivery outlet is arranged in center and/or at least one step of at least one spigot surface
The heart.By delivery outlet is arranged in center, the every side on delivery outlet direction all have identical spigot surface distance and/or
Step distance.So fleece just can be with identical speed from every side entrance delivery outlet.Speed difference can cause relative delivery outlet side
There is fleece compression or elongation phenomenon in face.And this phenomenon can cause being compacted in ribbon and produces thickening point and thinning point.
Ribbon quality will be improved by delivery outlet being arranged into center.
If step design is linear and/or to be parallel to each other to be favourable.Linear structure can be by plain mode by (comparing
As) milling process processing.If step is parallel to each other, then fleece deflects towards equidirectional with same degree at step.
The eddy current formed from each step is identical.Fleece is improved even into delivery outlet, ribbon quality.
Hereinafter design advantageous particularly: between at least one spigot surface and delivery outlet, arrange multiple step, and two steps it
Between arrange at least one median surface other, in particular by domes.By multiple steps, spigot surface and delivery outlet it
Between formed fleece eddy current will be strengthened.Fleece will more uniformly enter delivery outlet and export from fleece hopper.Two
Between individual step other, use the median surface of domes can improve band tack.
Hereinafter design similarly advantageous: at least one spigot surface and x direction angulation are 20 ° to 70 °, and especially 30 ° extremely
50 °, preferably 39 °.Larger angle produces steeper spigot surface so that fleece clashes into spigot surface with low-force degree and is directed to
To delivery outlet direction.This design has advantage when fleece high-speed motion, because when spigot surface is steeper, fleece can
It is directed to delivery outlet direction with protected state.If fleece needs with fast speed (i.e. by less Z-direction distance)
Be directed to delivery outlet, then smaller angle has advantage.Use smaller angle also can reduce fleece hopper height and extend size,
Thus save the installing space in machinery equipment and reduce cost.
One favourable optimization design is: median surface and/or spigot surface in the x-direction and/or Y-direction be designed as concave structure and/or
Convex structure.The motion of fleece thus can be affected by median surface and/or spigot surface.Such as, when using in y-direction
Have the advantage that during concave structure and on fleece hopper y direction, fleece can also be guided.At this moment fleece exists
It is directed to bottom the spill spigot surface of y direction.
Additionally, following design is favourable: step altitude range in a z-direction is 2mm to 10mm, especially 3mm
To 7mm.Higher step can strengthen the eddy current formed at step such that it is able to improves ribbon quality.
It is favourable for using following design: from step, the transition region to corresponding median surface has transition arc.This transition arc
Radius can (such as) between 3mm to 12mm.During this radius value 6mm more reasonable.By above-mentioned design,
Fleece can slip over step equably.Ribbon quality is thus improved.
Additionally, following design has the advantage that two corresponding steps ultimate range in the x direction is equivalent to fleece hopper and enters
Mouthful side needs the 50% to 80% of the web width of boundling, and especially 60% to 75%.Such as, when two corresponding steps are at x
Ultimate range on direction be equivalent to fleece hopper entrance side need boundling web width 80% time, two edges of fleece
The edge fibers of 10% clashes into spigot surface and slips over step.So, the fleece in only outside each 10% obtains torque produce whirlpool
Stream.The width adjusting two corresponding steps according to fleece translational speed will ensure that ribbon remains equal in quality.
If median surface and/or spigot surface have smooth or patterned surface is similarly advantageous.Smooth surface is easy to clean.Can
By a kind of coating process, patterned surface is applied chromium coating with (such as).Chromium coating can work as fibre with conical protrusions
When dimension net slips over chromium coating, these projections will form mattress.Thus can reduce frictional resistance, make ribbon with protected
Form is directed to delivery outlet.Patterned surface can be formed by japanning or machining.
Additionally, following design have the advantage that fleece hopper in the y-direction at least side by cover plate enclosing.Permissible by cover plate
Fleece hopper especially fleece is prevented to be contaminated.Cover plate can also undertake guiding into fleece of task, makes fibre in the y-direction
Dimension net is maintained in fleece hopper.
Delivery outlet can have the circular cross section of a diameter of 10mm to 30mm, especially 15mm to 25mm.Circular
Cross section can pass through plain mode (such as boring) processing.Additionally, can control to be compacted the compression of ribbon by diameter
Degree.Delivery outlet can also be installed single parts (as fleece nozzle).
Hereinafter design similarly advantageous: delivery outlet is arranged in the base plate of matrix part, base plate thickness be 5mm extremely
12mm, especially 6mm to 10mm.This design can simplify production process thus time-consuming and expense.
Additionally, arrange after delivery outlet that along web motion direction fleece guide is also a favourable design.Fleece
Guide is that the ribbon leaving fleece hopper guides after delivery outlet.Fleece guide can be designed as fleece and guides
Pipe, so that fleece guide has the shape of pipe.Fleece guide can (such as) have circle, ellipse and/
Or band corner angle cross section.Fleece guide can also have the cross section that same delivery outlet is the same.But this cross section can be more
Little or bigger.The ribbon of output also has certain length to be guided by fleece guide after fleece hopper.Logical
Crossing fleece guide is especially possible to prevent ribbon to scatter after delivery outlet.Such as, can be by fleece guide by fibre
Dimension bar is delivered to follow-up ribbon processing unit (plant), the rotary feed table being especially delivered in spinning can for depositing ribbon.
The ribbon cross section after fleece hopper can also be controlled by above-mentioned design.Therefore ribbon quality is improved.
Below design be favourable: fleece hopper size in y-direction be 40mm to 70mm, especially 45mm extremely
60mm, size in the x direction is 120mm to 160mm, especially 130mm to 150mm, and/or in z side
Size upwards is 30mm to 80mm, especially 40mm to 70mm.Can be according to web width by this design
Fleece hopper is carried out adaptive adjustment.
If the median surface arc radius using domes is 100mm to 200mm, especially 125mm to 175mm
Similarly advantageous.Bigger arc radius makes the gradient of median surface milder.Fleece is along substantially vertical direction collision
Between face.This design causes single fiber to produce intersection when collision, each other will not be the most parallel.Between single fiber
Band tack is thus improved.In contrast, less arc radius makes fleece by more uniform in the range of median surface
Be directed to delivery outlet.
It addition, following design is favourable: use the median surface of domes to upwardly extend a size of 30 in fleece hopper x side
Mm to 100mm, especially 50mm to 80mm.As described above, there is impact for band tack in median surface.
If fleece is along substantially vertical direction collision median surface, then ribbon there is the single fiber of major part to produce and intersect, also
That is the mutual hook of these single fibers is even.This situation improves band tack.If using wider median surface, then fiber
Net there is more single fiber collide median surface, thus have the mutual hook of more single fiber even.Can be right by median surface width
Band tack is exerted one's influence.
Additionally, following design has the advantage that the median surface using domes has the identical circle that the center of circle is identical with spill spigot surface
Arc radius.The median surface of employing domes and spill spigot surface become two parts of a common circular arc, and they are by step
Disconnected.This design makes fleece be directed evenly median surface from spigot surface.

6b and median surface 7a.The each several part of fleece hopper 1 is made up of matrix 8.Additionally, fleece hopper 1 is also with entrance side 2
With outlet side 3, fleece enters at entrance side, is compacted ribbon and leaves hopper at outlet side.It is designed with defeated at outlet side 3
Outlet 4.It is compacted ribbon to be exported from fleece hopper 1 by delivery outlet 4.In this topology example, delivery outlet 4 sets
Meter is in base plate 17, and base plate is connected on matrix 8.Here, base plate 17 and matrix 8 constitute fleece hopper 1.Base
Body 8 has the longitudinal extension 12 on x direction.Additionally, matrix 8 also has the height on z direction extends size 14.?
In another topology example, base plate 17 and matrix 8 can be designed as one.
Two spigot surfaces 5a, 5b it are designed with between entrance side 2 and outlet side 3.From z direction, the fiber do not drawn in figure
The edge fibers of net collides on corresponding spigot surface 5a, 5b, and spigot surface guides along delivery outlet 4 direction.Favourable way
Be: fleece from center enter entrance side 2, and and then therefrom the heart enter delivery outlet 4.By this measure, fleece will be from leading
Uniformly guided to delivery outlet 4 direction to face 5a and spigot surface 5b.Spigot surface 5a, 5b are α relative to the angle in x direction.
This angle is identical for spigot surface 5a, 5b, so only one spigot surface 5b has indicated angle and label symbol.
The angle [alpha] of spigot surface 5a and spigot surface 5b can also be different.If (such as) fleece enters fleece material in an inclined manner
Bucket 1, can compensate by two different angle [alpha].
It is designed with step 6a, spigot surface 5b between spigot surface 5a and delivery outlet 4 and delivery outlet 4 is designed with step 6b.Fleece
