Specific embodiment

The first embodiment of carding equipment 1 according to the invention is shown in FIG. 1, which has for dissipating The inlet side 1a of fiber is used for the outlet side 1b of web 20 with one or more.In the upstream inlet side 1a of carding equipment 1 It is disposed with unshowned feeder, such as vibra shoot feeder (R ü ttelschachtspeiser), it will using the feeder Staple in bulk is placed on unshowned conveyer belt.Conveyer belt is for example equipped with radio or optical measuring device or belt Weighing balance, the measuring device or the measurement of belt weighing balance place fibrous layer on the conveyor belt and data are conveyed to control Device.The process velocity of weight data and carding equipment 1 is balanced each other inside control device, thus the speed with constant The carding equipment of degree generates uniform web 20.Other than vibra shoot feeder, the carding equipment 1 can also be equipped with Carding machine feeder with integrated adhesive-bonded fabric measurer for thickness passes through adhesive-bonded fabric thickness in the carding machine feeder Degree measuring device determines weight.

In carding equipment 1, staple in bulk is conveyed by means of the inlet side 1a of equipment and passes through draw roll 2, preparing roller 3 It guides with transmission unit 4 to cylinder 5, so that staple in bulk is by shredding to single fiber and is aligned.In the transmission process phase of staple in bulk Between, stripper roller and processing roller 6,7 are held the fibers on preparing roller 3 or cylinder 5, so that web 20 is formed, the fiber Net is conveyed by doffer 8 towards outlet side 1b in 5 downstream of cylinder.In the described embodiment, cylinder 5 along rotate clockwise and will produce Raw web 20 is transferred on top and lower part counter-rotational doffer 8.In order to can be by web 20 by 5 turns of cylinder It moves on on doffer 8, a fairly small gap is set between cylinder 5 and doffer 8.In addition, the surface of doffer 8 is designed in this way, So that can produce form locking between roller surface and the fiber to be shifted.One or more pressure roller 9,9' and circular defeated The discharge unit of band 10,11 forms is sent to be adjacent to doffer 8, which when necessary can be equipped with one or more transfer Roller 12.

Carding equipment 1 has the adjustment element of multiple high power for fiber alignment, these adjustment elements for example can be with As doffer 8, pressure roller 9,9''s and/or omnidirectional roller servo-driver or Linear actuator, the servo is utilized to drive Dynamic device or Linear actuator adjust the mutual spacing and its differential of the roller 8,9,9'.In addition, servo-driver or line Property driver may be used as adjustment element, utilize the size in card wire gap of the adjustment element adjustment on cylinder 5.

For example, by pressure roller 9 relative to the lesser peripheral speed conpressed fibers net 20 of doffer 8 and herein by fiber along horizontal To redirection.But conpressed fibers net 20 leads to the desired weight per unit area for then improving web 20, thus web 20 is closer and therefore generate smaller production length.This causes the speed of production of subsequent equipment also to decline.In order to compensate for The unfavorable effect can reduce the staple in bulk of input in 1 upstream of carding equipment by the adjustment element of weight per unit area Amount, the layer of thinner staple in bulk is transported on conveyer belt as a result, but guided more quickly to carding equipment 1, thus single The regulated variable of position area weight is again close to the reference variable of weight per unit area.

Reach identical effect in the following way, that is, reduces the gap between doffer 8 and pressure roller 9.This also leads to fibre Thus the redirection of the reinforcement of dimension transversely improves the weight per unit area of web 20 and therefore reduces production length.? In two kinds of situations, MD/CD ratio is bigger.Multistage ground conpressed fibers net 20 has the following advantages that, that is, can relatively accurately adjust MD/CD ratio, wherein the maximum influence on fiber alignment is generated by the differential between doffer 8 and the first pressure roller 9.? Differential between first and second pressure rollers 9,9' improves desired result.

According to present invention provide that, along conveying direction follow cylinder 5, it is so structured that band or roller doffer wherein it One that is, such as doffer 8 on or be disposed on one of pressure roller 9,9' jet beam 16, the jet beam has multiple sprays Hole, each water jet 17 are struck with high pressure onto web 20 by the spray orifice.The fiber of web 20 is in the embodiment In mutually reinforced on pressure roller, thus web 20 have in further conveying when fiber alignment almost keeps identical it is bigger Intensity.In order to export the water of jet beam 16, pressure roller is configured to the pressure roller 9' of drawing-in type, and the pressure roller is put by unshowned pump It sets under negative pressure and exports water.Because the main roller and cylinder 5 of carding equipment 1 are used for directional fiber equipped with multiple Teeth portion circular needle cloth, so must be designed in this way by roller that jet beam 16 sprays 8,9,9', so that one side water is led Out and not as web is transported further, the productivity of carding equipment is not on the other hand reduced.

According to the prior art, needle cloth 30 is as being similar to the continuously long band of saw blade so spirally and closely It is abreast tensioned on roller, so that being had the gap not retaining between needle cloth pedestal 31 side by side.It is advantageous to can be, It is disposed with multiple recess portions 32 in needle cloth pedestal 31, the longitudinal axis of these recess portions or the lateral tooth flank ground cloth for being oriented parallel to teeth portion 33 Set or the longitudinal axis of these recess portions needle cloth 30 wind when alignment roller 8,9,9' axis.30 benefit of needle cloth in the described embodiment The periphery of the pressure roller 9' of drawing-in type is wound up into needle cloth pedestal 31, so that teeth portion 33 is on the outside of pressure roller 9' or in pressure On the circumference of roller.It can be closely in another needle cloth pedestal side or needle cloth by spiral winding needle cloth pedestal 31 It arranges with being spaced from each other distance, wherein recess portion 32 works as perforation, is led to the water of jet beam 16 by the recess portion Cross pressure roller 9' export.This details is described in Fig. 7 into Fig. 9.

In this embodiment, the pressure roller 9' of drawing-in type circumferentially has open that is, permeable structure, which can To be covered partially by the needle cloth 30 of winding.The open structure of adsorption roller 9 can be by porous surface or by adding The pipeline of the recovery entered generates.In addition, the adsorption roller 9 of drawing-in type is equipped with suction section in the region of end side, which is produced Raw negative pressure and the water that jet beam is sucked out.

It is that the reinforcing of fiber is in the teeth portion 33 of needle cloth 30 with the further difference of the prior art in this embodiment It is carried out between or.In the prior art, the reinforcing of fiber is at the porous conveying bottom of such as conveyer belt or porous roller It is carried out on plate, which has structuring or smooth and at least partly flat surface.Here, fiber part Ground is washed into hole and mutual eddy deformation or winding there.Meanwhile the water of jet beam being sucked out by the hole.It presses According to the prior art, jet beam is run with pressure in the range of 60 bars to 400 bars.In the present invention, fiber is in needle cloth 30 In teeth portion 33 and between be extruded or be pressed into.The loose combination of fiber is more closer than mutual eddy deformation between each other, from And the alignment of fiber or orientation be kept substantially it is identical.Therefore, with very small pressure duty, these pressure are according to cellulosic Amount can amount to no more than 40 bars, because otherwise the teeth portion 33 of needle cloth 30 punches web 20.Therefore, in the embodiment In, with pressure and the water work that may be significantly smaller than the prior art.In addition, the roller 8 of drawing-in type, 9,9' has than in traditional liquid The much smaller diameter of roller is sucked out in the ruggedized equipment of pressure power, this means high challenge for the transporting of water.
