Description
The present invention relates to the removable enhancing element on a kind of pressure roller matrix that can be set to spinning machine drafting component, described enhancing element comprises a thin enhancing sleeve pipe and a flexible roll covers, this roll covers has the operation surface that is used for fibrous material, and be connected the enhancing sleeve pipe securely, wherein, this enhancing element is cut into required working width from a long tubular body.
Use the spinning process of traction component to make spinning speed can reach per minute hundreds of rice now.Especially in so-called air-jet spinning technology.In such spinning assembly, very high requirement has been proposed also the drafting component that is installed in the upstream.7000 rpms of the commentaries on classics scooters of the outlet roller of high speed drafting component.
In this speed, the roll covers of pressure roller will wear and tear in the very short time.The roll covers of the pressure roller that outlet roller is right just has to polish again after having moved 3-5 days.But pressure roller at most can only be polished five times, because diameter of roll covers becomes too little after this.Therefore, now, the roll covers of this pressure roller is removable, wherein on the pressure roller matrix of spinning machine drafting component, be provided with a nestable enhancing element, this enhancing element comprises that one thin is normally made the enhancing sleeve pipe by aluminium alloy, flexible roll covers can for example pass through, and sulfidation is connected with the enhancing sleeve pipe securely.Roll covers comprises a real table that is used for fibrous raw material.Now, in the middle of the reality, the removable enhancing element of being made up of enhancing sleeve pipe and roll covers all is to manufacture a long tubular body, and then this tubular body is cut into the working width that needs by shearing device.Then, the enhancing element that cuts out through reprocessing a little after, be pressed on the corresponding pressure roller.
Strengthening the comprising of the above-mentioned type the removable enhancing element of sleeve pipe and the flexible roll covers that firmly is connected with it, is prior art, for example, and German 2061434 or US6237196.In such enhancing element, owing to be that a long tubular body is cut off, the width of roll covers is identical with the width that strengthens sleeve pipe.But like this owing to system's reason can produce several shortcomings, because the requirement of contradiction own should be satisfied simultaneously.On the one hand, strengthening element should be narrow as much as possible, so that the right roll covers of the outlet roller of drafting component can on fibrous raw material, apply must pressure, and on the other hand, strengthening element should be enough wide, strengthen the edge bearing region that sleeve pipe can cover the pressure roller matrix so that make, enter bearing region to stop fiber and yarn and thread head.
Deutsche Bundespatent 908459 discloses a kind of special prior art, and in this technology, roll covers is narrower than strengthening sleeve pipe.By this enhancing element, though can overcome above-mentioned shortcoming,, the time that the prior art produces is to strengthen element also not make and cut into required working width by a long tubular body.But an enhancing sleeve pipe at first is made into required width, and then, roll covers cures thereon.Roll covers is a condition with technology than strengthening the narrow situation of sleeve pipe in this manufacture.
The purpose of this invention is to provide a kind of removable enhancing element of the above-mentioned type that can make by a long tubular body, can satisfy above-mentioned conflicting requirement at this enhancing element.
According to the present invention, the object of the invention can be as the realization of getting off, and promptly roll covers is removed (abdrehen) two stub areas by car, makes that strengthening sleeve pipe extends laterally roll covers.
Basis of the present invention is as above-mentioned the tubular semifinished of required working width that be cut into of the prior art.Roll covers is made into to be narrower than the enhancing sleeve pipe subsequently.Therefore, two conflicting requirements can be satisfied, that is, can obtain high clamp pressure on the one hand, and on the other hand, can form a sufficiently long seal clearance to the bearing region of pressure roller matrix.In addition, also have a good advantage, that is, go, formed the metal surface that enlarges on the surface that strengthens sleeve pipe by the car that roll covers is distinguished endways, can be rapidly and distribute the heat that produces in the operation process effectively by this metal surface.
Roll covers side direction car is gone and needn't carry out after being cut into required work range, but if necessary can before cutting, just can carry out.Under a kind of situation in back, strengthen element and be provided, increase in the element at this, it is wide than roll covers to strengthen sleeve pipe.Only need carry out in short-term reprocessing then at each end face.
For the described element that respectively strengthens of above-mentioned prior art, described advantage can also realize in the following way, being about to subring is installed on the enhancing element at two end face ends that strengthen element, described subring contacts with the enhancing sleeve pipe, but be provided with roll covers, and the internal diameter of described subring is identical with the internal diameter that strengthens sleeve pipe.In this case, roll covers needn't be made into to be narrower than the enhancing sleeve pipe by reprocessing, but two subrings are rested on by side direction and strengthen on the sleeve pipe, and these two subrings have and strengthen the roughly the same diameter dimension of sleeve pipe.In this way, also can obtain having the roll covers of the relative narrower of high clamp pressure, simultaneously, the subring by covering the bearing district is distribute heat well also, because subring directly contacts with the enhancing sleeve pipe.
For this purpose, strengthen sleeve pipe and extending laterally the zone that exceeds roll covers, compare with the zone line that covers by roll covers, have less external diameter.Therefore, when roll covers is gone by car, produce a very little convex shoulder, be roughly the 0.1mm height.Take above-mentioned measure, can improve the rotation that strengthens sleeve pipe because the roll covers of polishing more not only, and strengthen sleeve pipe to stretch out the zone also all processed.
In constituting the present invention program, strengthen sleeve pipe or under the situation of using subring, the latter has big slightly internal diameter in its end face stub area.Internal diameter increases similar 0.5mm, and it is very narrow with one of the outer shroud formation of giving the bearing correspondence then, for example, the seal clearance between 0.2mm and the 0.3mm, the sealing gap accurately is fit to work as precondition.Big slightly internal diameter allows that also a little convex shoulder is arranged on the outer collar of outer race, this convex shoulder can prevent that loose fibres from entering seal clearance.
Following description to several embodiment will be showed other features and advantages of the present invention.

The embodiment that Fig. 6 is similar to Fig. 1, wherein, subring is rested on by side direction and strengthens on the element,
Fig. 7 amplifies the partial view in a lot of Fig. 2 mid point scribed circle VII zones.
Device shown in Figure 1 is used to make the spun yarn 1 of staple fibre yarn 2.The chief component that this device comprises is a spinning machine drafting component 3 and a jet assembly 4.The following description of this device only is used to the practical use of the present invention of illustrating that the back will be described.
Staple fibre yarn 2 on feeding direction A the feeding drafting component 3 to be spun according to Fig. 1 withdraws from as spun yarn 1 on transport direction B, and continued to guide to the coiler device (not shown).
Only be spun into the drafting component 3 shown in the part and be preferably designed to three drafting components, it is right always to have three rollers, and the every pair of roller has a driven bottom roll and elasticity to press pressure roller on it.Roller is sent roller to 5,6 and one and is installed in the downstream of a front roller to (not shown in figure 1) to 9,10, and described roller has guiding belt 7,8 to 5,6.What Reference numeral 5 and 9 indicated respectively is driven bottom roll, is corresponding pressure roller and Reference numeral 6 and 10 indicates.In this drafting component 3, staple fibre yarn 2 is drawing to needed fineness in a known manner.There is a fine fibre bundle 11 from the downstream of drafting component 3,, also do not have twisting though it is drafted.
According to the present invention, be installed in the very approaching downstream of drafting component 3 distance, can be make arbitrarily to the jet assembly 4 of yarn twisting, wherein, serve as preferred with the make that allows especially high rate of delivery.
Fibre bundle 11 is via the jet assembly 4 of admission passage 12 feedings.The downstream is a so-called minor air cell 13, and therein, fibre bundle 11 is formed spun yarn 1 by twisting, and spun yarn passes yarn extraction passage 14 then and withdraws from.
The compressed-air atomizer of fluid means by tangential remittance minor air cell 13 is blown into compressed air and produces eddy current in minor air cell 13.Be discharged from by a blast pipe 15 from the compressed air of fumarole ejection, wherein, this blast pipe has a ring section that is centered around the stationary element 16 of spindle shape, and this stationary element 16 comprises extracts passage 14 out.
In the zone of minor air cell 13, the seamed edge that the fiber guidance surface is set is as the twisting locking device, and this guidance surface is installed in yarn and extracts out in the entrance region of passage 14, and eccentric a little with respect to extracting passage out.
In this device, fiber to be spun is held in the fibre bundle 11 on the one hand, then from admission passage 12, almost need not twisting, and the feeding yarn is extracted passage 14 out.On the other hand, fiber is subjected to the influence of eddy current in admission passage 12 and yarn are extracted zone between the passage 14 out, eddy current cause they or at least the import of being extracted out passage 14 from yarn of their stub area expel diametrically.By the yarn 1 of above-mentioned explained hereafter have roughly along the yarn longitudinal extension without any basic twist heart yarn or heart yarn district, and outer zone, in this zone, fiber or pars fibrosa are twisted around heart yarn.
According to typical an explanation, this yarn texture forms in the following way, it is the front portion operation end of yarn, especially also hold in the front portion operation that admission passage 12 grips when those rear portions, directly arrive yarn basically and extract passage 14 out in the upstream, yet, pars fibrosa following closely, especially when they no longer are held in the inlet region of admission passage 12,, twisted around the yarn 1 that forms then because the formation of swirling eddy is dragged from staple fibre yarn 11.In either case, fiber both had been incorporated in the yarn 1 of formation at synchronization, and they are drafted by yarn path 14 like this, are subjected to the effect of eddy current simultaneously again, eddy current promptly quickens yarn eccentrically away from the inlet port of yarn extraction passage 14, and yarn is drawn in exhaust passage 15.Since the effect of eddy current by drag from fibre bundle 11 from pars fibrosa form one and import yarn and extract fiber eddy current the inlet of passage 14 out, it is so-called sun shape (sonne), the part that the fiber eddy current is grown shape in the shape of a spiral is centered around the outside, inlet region that yarn is extracted the spindle shape of passage 14 out, and in this spiral in the opposing blast pipe 15 active force of air-flow pulled, near the inlet of yarn extraction passage 14.
Such device is allowed extra high spinning speed, and this speed can reach 600m/min.Clearly, the requirement of counter extensioin assembly 3 is very high, because, because the needs of high drawing-off performance are sent roller and are had to turn round very soon to 9,10.This speed that must cause the roll covers 20 of pressure roller 10 to wear and tear is very fast, has to change.
As mentioned above, roll covers 20 must be polished once more, but can only be had at most five times altogether after operation several days.Afterwards, the external diameter of roll covers 20 becomes too little.
As shown in Figure 1, send roller 9,10 pressure roller 10 is comprised a pressure roller matrix 17 and a removable enhancing element 18.Strengthen the roll covers 20 that element 18 comprises an enhancing sleeve pipe 19 and has the running surface 21 that is used for fibrous raw material.In the replacing process, strengthen suitable more changing device of element 18 usefulness and leave behind from matrix 17, to replace with a new enhancing element 18 then, this enhancing element is compressed against on the old matrix 17.
Shown in Fig. 2 is to send the axial cutaway view of roller to 9,10 pressure roller 10.Can see matrix 17, by strengthening enhancing element 18 and the operation surperficial 21 that sleeve pipe 19 and roll covers 20 are formed.
Axle 22 lateral-supportings of pressure roller 10 are in rolling bearing 23 and 24, and the lid 25,26 that these two rolling bearings are comprised outer race simultaneously covers respectively.Between enhancing sleeve pipe 19 and two corresponding lids 25,26, can see that a seal clearance 27 is arranged, will in conjunction with Fig. 7 sealing gap 27 be described in further detail below.
Just as can be seen, roll covers 20 is gone by car in two end region 28 and 29, makes that strengthening sleeve pipe 19 extends laterally roll covers 20.Therefore, self-contradictory demand own can be satisfied, just, on the one hand, because because sending the narrow roll covers 20 of roller on, to obtain high clamp pressure, on the other hand to 9,10, an enough wide enhancing sleeve pipe 19 also will be arranged, and this strengthens the effective seal clearance 27 of cover and hides side direction lid 25,26.In addition, will produce the zone that is not covered at the end that strengthens sleeve pipe 19 like this by roll covers 20, thereby in these zones,, therefore avoid these heats to be delivered on rolling bearing 23 and 24 in undesirable mode because the heat that produces that runs up can promptly distribute.
In Fig. 3, removable enhancing element 18 is shown separately, what the present invention referred to is exactly this enhancing element.This strengthens element 18 under the situation of roll covers 20 wearing and tearing, in case this roll covers can not be polished once more, is just changed fully together with reinforced pipe 19.Remove roll covers 20 by zone 28 and 29 cars endways, can reach the state that reinforced pipe 19 becomes wideer than roll covers 20, so just produced above-mentioned advantage.Can further see, after enhancing element 18 intactly is provided, on roll covers 20, be provided with side direction hypotenuse 30, and be provided with inclined-plane 31 at the end region that strengthens sleeve pipe 19.
Shown in Figure 4 is semi-finished product 32, strengthens element 18 and produces thus after being provided.These semi-finished product 32 are cut into a work range c, comprise that also one does not also have processed enhancing sleeve pipe 33 and one at first not have processed roll covers 34.
Shown in Figure 5 is the conduct half-finished long tube body 35 littler than actual size, will make each by this long tube body and strengthen element 18.The long sleeve pipe 36 that enough is used for a plurality of pressure rollers 10 has isometric cover layer 37, and this cover layer firmly is connected with sleeve pipe 36, for example, and by sulfuration.This tubular body 35 then is cut into required working width c, just, and in those position cuttings that marks with chain-dotted line.The result just becomes the semi-finished product 32 shown in Fig. 4.
Different with said process, cover layer 37 certainly also can tubular body 25 should cut position by in advance roughly car go.Thus, have only sleeve pipe 36 to be cut into required working width c, and cover layer 37 with Fig. 2 in required the same narrow.
Shown in Figure 6 is a distortion, and it also is to obtain from shown in Figure 5 one long tubular body 35, strengthens element 18 ' but be provided with therein, and the width of the roll covers 20 ' of this enhancing element is identical with enhancing sleeve pipe 19 '.Generally speaking, the working width e of enhancing element 18 ' is narrower than existing.
According to Fig. 6, not only strengthen element 18 ' and be compressed against on the matrix 17, and subring 38 and 39 also side direction is adjacent is pressed against on the matrix, the inner diameter d of subring is corresponding with the internal diameter that strengthens sleeve pipe 19 '.Subring 38 and 39 and strengthen the end face of sleeve pipe 19 ', thus the heat that strengthens on the sleeve pipe 19 ' can be delivered on subring 38 and 39 well, is dispersed in the atmosphere more therefrom then.Utilize this design, pressure roller 10 can realize that also enough narrow for obtaining high clamp pressure roll covers 20 in this pressure roller, simultaneously for obtaining enough seal clearances 27 and good thermal diffusivity, the wiping bearing that rolls is covered.
Fig. 7 is that amplify the part of Fig. 1 mid point scribed circle.
Can partly see matrix 17 once more and strengthen element 18 that this enhancing element has an enhancing sleeve pipe 19 and the narrower roll covers 20 through reprocessing.Roll covers 20 also has a hypotenuse.The above-mentioned lid 26 that comprises outer race covers rolling bearing 24.
Because the car of roll covers goes, on enhancing sleeve pipe 19, form the zone that extends laterally 40 that does not have roll covers.The external diameter in this zone 40 is slightly smaller than the external diameter of reinforced pipe 19 zone lines that covered by roll covers 20.Consequent little convex shoulder 41 nearly 0.1mm height.
The distolateral stub area 42 that strengthens sleeve pipe 19 is reprocessed in one way, and promptly strengthening sleeve pipe 19 has a ratio big slightly internal diameter before there.The internal diameter of distolateral stub area 42 is approximately than the big 0.5mm of internal diameter of the central region that strengthens sleeve pipe 19.Because these measures, on a position on the above-mentioned lid 26, be provided with a little convex shoulder that 0.2-0.3mm is high, the corresponding distolateral stub area 42 that strengthens element 19 in this position forms a seal clearance 27 that very accurately limits like this, and its gap is approximately between 0.2-0.3mm.Convex shoulder 43 importantly stops the loose fibres raw material to arrive seal clearance 27 from the beginning.
Distolateral stub area 42 long enoughs, the heat of allowing generation in service is passed to the air from strengthening sleeve pipe 19, does not distribute and roll covers 20 can trap heat.
