Description
Technical field
The present invention relates to a kind of stretching-machine of annular weaving loom of the compressor reducer that has a fiber band as described in the preamble as claimed in claim 1.The present invention also relates to a kind of and is used for parts according to stretching-machine of the present invention.
Background technology
Natural fabric and artificial fibre are changed a series of minute process of resultant yarn requirement.A last process segment usually is called spinning.Obtain its final fineness and toughness at this yarn that is spun into.The described spinning sizable part that needs the whole spinning process cost of cost.Adopt as heir traditional hand spinning, occur by the known annular spinning of prior art with spinning wheel.Be wound at this spun yarn on the yarn axle of rotation.Weaving needs three kinds of machines in fact for annular.Also be called the not base yarn of twist ribbon with flier from the fiber band generation.Producing the yarn that has necessary toughness and spin at little bobbin from the base yarn with annular weaving loom is on the spool.Winder gathers the yarn from many spools become together and produces the yarn tube that can use of several approximately kilogram weights.
On annular spinning machine the base yarn being drawn into desired fineness and having obtained is that the needed fiber of spinning is stranded.The general bilateral of this machine ground constitutes, and to have a plurality of spindles on every side be yarning position.Each yarning position is respectively arranged a stretching-machine.Relate to so-called three cylindrical stretching-machine at this majority.This stretching-machine has a predraft district and a main drawing zone.The base yarn of feed becomes required fineness and is wide relatively fiber band when the right clamping line of outlet roller leaves stretching-machine in stretching-machine.
Described fiber band rotates stranded by means of spinning and accumulates the finished product yarn.On the right clamping line of the outlet roller of terminal stretching-machine, constitute so-called spinning triangle at this, wherein the fiber that provides by stretching-machine of amalgamation and integrate yarn formation structure.Be not that all fibers are all accommodated into spinning triangle.The yarn of rotation may be lost or can only partly be accumulated into to the edge fiber.Fiber on the edge of spinning triangle sending when rotation in fact consumingly tensioning become to be in the fiber at spinning triangle middle part.Therefore the fiber at periphery is subjected to prestressing force more than the fiber in the yarn core in the finished product yarn.When correspondingly higher yarn is loaded, at first ruptured by higher prestressed yarn.Therefore the yarn spooled of finished product does not have to become the toughness of the corresponding toughness of single thread.The fiber that gathers uncontrollably is away from the yarn of spooling, and causes increasing the fluffing of undesirable yarn.Increase fluffing property and be equal to compromised quality.
For big as far as possible degree avoid spinning triangle and disadvantageous consequence thereof, in the stretching-machine of annular spinning machine of modern times, expand drawing zone with the compressional zone, in described compressional zone, compile as far as possible densely by outlet roller to output wide fiber.The fiber band that only in this way is compressed or encrypted is just picked up commentaries on classics later on together to make yarn in the compressional zone.The compression set of known a kind of pneumatic work in the specification 1646e-BBAB-15 of Fa.Rieter, Winterthur for example.This known pneumatic compression device comprises the cylinder that is equipped with the hole, mainly contains low pressure in described cylinder.This low pressure produces air-flow by the cylinder that is equipped with the hole and compresses the fiber band of carrying by described cylinder thus on request.The compressor reducer of pneumatic work is expensive in purchasing and maintaining.Produce the needed low pressure of compression and need higher energy input.Be subjected to higher relatively wearing and tearing for the needed parts of conpressed fibers band more for this reason.Although the fine and close yarn that produces by pneumatic compression is better qualitatively, however more expensive than the annular spinning of routine significantly.
The also known stretching-machine that is equipped with the annular spinning machine of the compression set that how much-machinery works.Their costs that usually can suit are realized.Comprise the compression member of the brill piece sample in the transmission aspect that is arranged in fiber band at this each compression set.Be provided with the compression tank circuit of groove sample in its described compression member in side towards fiber band, the described compression tank circuit gradually constitutes in the input side infundibulate ground expansion of fiber band and along the throughput direction of fiber band carefully.Fiber is crowded together and is compressed into desirable diameter by the compression tank circuit that narrows down by compression member conveying fiber band the time.
A known enforcement become the compression member that less relatively structure is arranged in the main drawing zone at stretching-machine in the example be arranged in the stretching belt that is located in the main drawing zone and outlet roller between.The stretching of fiber band and compression are carried out simultaneously in this arrangement of compression member.Disturbed the even stretching of fiber band at this.In order to create the position of compression member, the clamping line of outlet roller and the distance between the stretching belt have been strengthened.Also strengthened thereon the not distance of conveying fiber thus.Disturb stretch uniformly and must do not carry yarn sent back to the original place distance may cause inhomogeneities and diminish its quality.Compression member is interfered when handling stretching-machine and owing to its relatively little structure is easy to lose.
Also exist the compression member that how much-machinery is worked to be arranged in possibility in the compressional zone that is connected on the drawing zone back in theory.
In such arrangement, fiber must cross outlet roller pair and be located at the compressional zone outlet donor rollers between distance, and do not have the carrying device that supports.In many materials, for example under the situation of cotton, most fibers are shorter than the distance that will cross in the compressional zone.In the compressional zone that after this only just realizes compression member is arranged in when the outlet roller of stretching-machine has many fibers to the every cross-sectional unit of the fiber band that provides, connects.Only in this way could guarantee that fiber band be not subjected on the carrying device support distances in supporting voluntarily to a certain extent.For example also claim in the flier to be exactly this situation at pre-frame.In pre-frame, produce the ribbon of thick relatively not twist, the annular spinning machine of postposition, produce the finished product yarn at last from the ribbon of described not twist.Since in the spinning machine of this form usually the outlet roller of stretching-machine to after thick like this fiber band is not provided, in the compressional zone of the also inapplicable so far annular spinning machine in postposition of the arrangement of described compression member.
Summary of the invention
Task of the present invention is to avoid the shortcoming of prior art.Should improve stretching-machine as follows, make it and to produce the highest qualitatively yarn, promptly so-called solid yarn in cost efficient ground.At this pneumatic equipment that no longer cost of use is very high and expensive wearing terrain.Although improved stretching-machine, should keep the compact structure of the known stretching-machine of prior art.Also should pay special attention at this, can also be used for existing annular spinning machine, and need not carry out the repacking of high cost for this reason according to improvement of the present invention.
The finishing of this task be the to have the right stretching-machine of annular spinning machine of the compressor reducer that has fiber band of the described feature of characteristic of requirement 1.It is the subject matter of dependent claims that expansion of the present invention and/or favourable enforcement become example.
The present invention proposes, and connects in the compressional zone of drawing zone after the compression member with how much-mechanism of the compression tank circuit is arranged in, and is provided with the carrying device that supports fiber band in the compressional zone.
The solution of the present invention avoids above-mentioned wherein compression member to be arranged in the shortcoming of the stretching-machine in the main drawing zone.After be connected on the compressional zone of drawing zone problem walk around in this wise: fiber band is along supported by the carrying device compressional zone on its whole transmission highway section.No longer include stretching in the compressional zone.Yarn compresses very equably by compression member, and this advantageously works to the quality of yarn.By can not re-use the compression set of the pneumatic action that costs a lot of money according to the solution of the present invention.By the inhomogeneities of having avoided the yarn that in having the stretching-machine that is arranged in the compression piece in the drawing zone, may occur in the rearmounted compressional zone that is arranged in according to the present invention.The quality of the yarn that draws is good and have the power of striving unexpectedly aspect the obviously low cost especially.
At a very favorable carrying device of implementing to constitute by following cylinder in the change example fiber band in the compressional zone of the present invention, support output press roll thereon and provide pressure roller.Implement to become the peripheral part traveling of cylinder under the edge, compressional zone in the example at this.Following cylinder can have bigger diameter with respect to the stretching-machine of known routine, thereby output press roll and provide these two rollers of pressure roller and can easily successively find position and compression member can be arranged in simply between these two rollers, this is favourable in the annular spinning machine of staple fibre processing usefulness especially.Although it is feature with unusual compact structure also that its cylinder dilated diameter, this enforcement become example.The stretching-machine of Gou Chenging is only long slightly than conventional stretching-machine like this.Fiber band is along the surface support that is subjected to down cylinder on the whole fore-and-aft distance in compressional zone.
Output press roll and provide pressure roller and be installed in preferably by elastic force and be pressed in down on the support on the cylinder primely.For example be used to thus to load once or a center leaf spring of two pressure rollers abundant.Described leaf spring is fixed on the described support and rests on the parts of a fixed-site of stretching-machine.Loading spring can also be installed on the parts of fixed-site and be supported on the described support.For example the parts of described fixed-site be pressure arm, the especially lower roll of the pressure roller of the stretching-machine arranged on top descend in other words cylinder to the drawing zone of extruding.
The transfer path of fiber band from the output clamping line of output press roll and following cylinder extend to provide pressure roller and following cylinder provide the clamping line.Its length is less than 1/3rd length that are embedded in the fiber in the fiber band.Reach thus, fiber in the compressional zone transmits and controls by the fiber that is subjected to dual clamping, and the described fiber that is subjected to dual clamping is all length greater than the fiber of the transfer path by the compressional zone.For example avoided thus since compression member the interference of inhomogeneities of braking action fiber band that fiber is produced.
The compression member of described how much-mechanism has a compression tank circuit.The described compression tank circuit can be arranged in the downside of the compression member of the cylinder that faces down, and perhaps is arranged in towards the upside of the compression member of pressure roller.In each case, if compression member is placed on the cylinder down and is favourable thereon with defeating of can being scheduled to seamlessly pasting on its operating position.Thereby avoided fiber to arrive at down uncontrollably between the contact-making surface of cylinder and compression member.Compression member for example produces by its deadweight or by a pre-device of machinery or by magnetic force the pressure of following cylinder.The combination of described possibility can also be arranged.
Be connected with a pull stap in the compression member described in the enforcement change example of a simple especially stretching-machine, described pull stap holds down the above circumference of cylinder 180 degree.Be carried when the following cylinder rotation on the parts of the fixed-site that rests on stretching-machine from this pull stap and/or the outstanding convex shoulder of compression member together with the described pull stap of compression member fixed thereon, preferably resting on the axle that provides pressure roller.The clamping line that measure by this simplified structure provides between roller and the following cylinder is relatively accurately located described compression member.
For prevent lift provide roller and when down cylinder further rotates pull stap rotate along with cylinder down together with compression member, be provided with an outstanding backstop on pull stap, the parts that described backstop is in operation with the fixed-site of stretching-machine have very little distance.Provide roller and unclamped convex shoulder on pull stap and/or the compression member thus if lifted, the following cylinder that the pull stap that has compression member is merely able to follow rotation withstands on up to backstop on the parts of fixed-site of stretching-machine.For example the parts of described fixed-site are the prerotation vanes of the spreading belt in the stretching-machine.Again move and get back in the operating position if provide roller, take back its operating position again thereby pressure roller shaft is pressed on the described shoulder and compressor reducer.
For structural reason, if the compression member of arranging on the pull stap that two of each pull stap carryings are arranged in the centre, it is suitable that the fact shows.
Become pull stap and the compression member described in the example in very simple and enforcement cost efficient of the present invention constitutes integratedly.Preferably they use batch techniques, for example make with plastics with Shooting Technique.
Compression member rests in its operating position and provides on the pressure roller in another enforcement change example of the present invention.Output press roll not by compression parts touch.Compression member supporting surface radius to a large extent balanced support following cylinder and provide the radius of pressure roller.This is favourable especially in the supporting surface to following cylinder: do not have fiber can arrive between the supporting surface and following cylinder of compression member.
Provide between pressure roller and the following cylinder in order to prevent that compression member is clipped in, constitute the supporting surface of compression member aptly in this wise: make to draw some locating surface on the pressure roller providing perpendicular to the traveling of stretching-machine plane.Seamlessly lean against on the following cylinder in this compression member.For the disadvantageous expansion of the fiber that can after compression member, no longer occur compressing, the output of compression member is shifted near as much as possible the clamping line that provides pressure roller and following cylinder.Yet, providing between pressure roller and the following cylinder in order to prevent that compression member is clamped in, compression member not exclusively extends to described clamping line and does not touch herein and provides pressure roller.
Become in the example in a favourable enforcement of the present invention, compression member can be lifted from following cylinder with providing pressure roller, and in the time of for example should lifting the clamping line that provides pressure roller in short time, thereby yarn is rotated further in the compressional zone.
In order to realize the liftable property of compression member simply, enlarge the compression member of formation output press roll in this wise: make it and to lift with two pressure rollers with the top, zone that provides the minimum range between the pressure roller.When lifting described roller, just lift compression member simply together.
Become the compression member described in the example in another favourable enforcement of the present invention and be provided with one or more permanent magnet.Described permanent magnet cooperates with the carrying device of fiber band, especially cooperates with following cylinder.When mechanical oscillation, also can seamlessly be pressed in down on the cylinder and do not promoted a little even guarantee compression member thus, and not have fiber can arrive between the cover of compression member and following cylinder.
For the uniformity of yarn, pressure roller shaft is upwards immovably fixing also to suit if compression member is to providing.This is for example undertaken by convex shoulder on the compression member or projection, and described convex shoulder or projection overlap joint provide the side of pressure roller or output press roll.Described convex shoulder or projection for example are the plastic plug that is permanently connected with compression member.Coloured material on described convex shoulder or projection can play the indicator of the compression tank circuit.The user can directly read the scope which type of yarn corresponding compressor reducer is suitable for thus.
The pull stap that is attached thereto under compression member and the certain situation can be used plastics, ceramic material, perhaps can also use metal, and for example steel or mixture constitute.
In order to prevent that fiber from arriving at down between the compression member of cylinder and how much-mechanically effect uncontrollably, if cylinder has not by interruption, disconnection or analog ground and the periphery that constitutes smoothly to a great extent and suits down.By described level and smooth surface, compression member closely contacts with described periphery and fiber is merely able to arrive in the compression tank circuit.Adopt level and smooth following cylinder for the drawing of fiber band is immaculate equably, because the fiber that twice ground clamping successively come out from drawing zone.To the output of drawing zone, also do not obtain down the fiber on output clamping line of whole peripheral speeds of cylinder, obtain this peripheral speed at the output that provides on the clamping line, in the compressional zone laterly.Act on its length thus and longitudinally support the work of compression member greater than the little tension force on those fibers of the length in the transmission highway section by the compressional zone in an advantageous manner.
Under constituting smoothly during the periphery of cylinder, the fact show if down the periphery of cylinder to have the higher coefficient of friction of fiber in the traveling zone of fiber band at least be favourable.This for example can coating reaches by chemically or electrolytically handling in other words in the traveling zone at fiber band at least in the periphery of cylinder.For example the periphery at following cylinder is provided with nickel-diamond coating in the traveling zone at fiber band at least.
In one of stretching-machine of the present invention favourable expansion,, before output press roll, arrange a mechanically fiber band guiding piece of effect at the output of drawing zone.In this wise the guiding piece of fiber band is aimed at stretching-machine at this: make the guiding tank circuit of its fiber band roughly in of the compression tank circuit traveling of middle heart to compression member.The fiber of part is carried in the past on the compression tank circuit from the side in the fiber band that the fiber band guiding piece of the output machinery of drawing zone prevents to be carried by oblique compression member ingate.Because the inhomogeneities in the fiber band that is stretched, wear and tear output press roll and/or cylinder down unevenly, fiber band also is subjected to the lateral displacement to its assigned position in its transport process.Described lateral displacement may cause the peripheral region of fiber band to be directed in the past to providing pressure roller in the compression groove roadside.This causes the quality of yarn to descend.The fiber band guiding piece counterproductive with it of machinery, wherein be transmitted in that the inlet of the compression tank circuit is other in its guiding by the side direction of machinery territory, lateral areas of preventing fiber band.If this fiber band guiding piece have less than the compression groove degree of having a lot of social connections of compression member porch effectively pass through width, the fact shows it is favourable.The width that effectively passes through at this fiber band generally is the width of the guiding tank circuit at the neighbour place of its outlet or outlet.The described guiding tank circuit can be equipped the side directed wall of two almost parallel ground travelings.But it also can export from entering the mouth to with attenuating a little on its width before output press roll and be configured.
Implement to become in the example and can draft at of the present invention another, can arrange described fiber band guiding piece in lateral displacement ground.The fiber band guiding piece can laterally be moved with the direction of transfer that compression member is approximately perpendicular to fiber band when needed.Also can keep when being aligned in lateral displacement by mutual relative of these two parts of lateral displacement assurance of binding fiber band guiding piece and compression member.
Annular spinning machine according to the present invention is advantageously equipped the change example according to stretching-machine of the present invention.Such form spinning machine can provide the yarn of the densification of cost efficient, and its quality can be compared with the quality of the relatively costly fine and close yarn that produces in the machine of prior art.
The stretching-machine that constitutes according to the present invention for example is the new-type structure parts of the annular spinning machine of structure in other words.Also enable to reequip the stretching-machine of existing annular spinning machine according to formation of the present invention.Can become in the example a favourable enforcement for this reason and draft a kind of compression roller unit, described compression roller unit is settled a stretching-machine on the position of existing output press roll.Described compression roller unit comprises an output press roll and one and provides pressure roller, and they are installed on the public support.From outstanding leaf spring of described support or analog, this leaf spring under installment state, rest on the parts of fixed-site of stretching-machine and pressure roller to being pressed in down on the cylinder.Can on meaning of the present invention, replenish rearmounted compressional zone to the existing stretching-machine of prior art with the relatively simple compression roller unit of structure.
At this, if corresponding two supporting pressure rollers to the left side of the support that is installed in the center and arranges and right, the fact suits with showing.Described supporting pressure roller is on the fixing parts of correspondingly being arranged in pairs and be installed in stretching-machine by support.Advantageously, described fixed part is pressure roller, the especially drawing zone of stretching-machine that top is correspondingly arranged, is pressed in the pressure arm on lower roll or the following cylinder.
Preferably described compression roller unit is equipped with compression member, described compression member for good and all be fixed on a supporting pressure roller between the gap in.Compression member described herein advantageously has the substantial prismatic body that has the general triangular cross section.The radius of its supporting surface is balance stretching-machine following cylinder that supports and the radius that provides roller to a great extent.In described body, arrange magnetic to be used for compression member is fixed on cylinder down.Because than less wear, accurate machinability and DIMENSIONAL STABILITY, described compression member preferably is made of ceramic material or plastics ceramic mixture.Yet it can also constitute with plastics or metal.
The fiber band guiding piece that also has a machinery at the compression roller unit described in the favourable expansion.Described fiber band guiding piece for example for good and all is arranged on the output press roll.Under the state of installing, the fiber band guiding piece is arranged in the drawing zone of stretching-machine.The fiber band guiding piece has the guiding tank circuit of fiber band, and the guiding tank circuit approximate centre of described fiber band ground is to the compression tank circuit arrangement of compression member and have A/F less than the width of the porch of the compression tank circuit in compression member.The enforcement of this compression roller unit becomes example and keeps all necessary and superior to cost efficient ground workmanship necessary parts of yarn of formation stretching-machine of the present invention.
As further improvement, in compression roller unit, can also draft, but lateral displacement ground arranged fiber band guiding piece and compression member, and lateral displacement together when needed.The combination of the being displaced sideways property of fiber band guiding piece and compression member makes when needed, can stably utilize fiber band by the compressional zone for example around output press roll with provide pressure roller and/or the lateral displacement that target is arranged of the transfer path of cylinder down.
Implement to become in the example and can draft at of the present invention another, compression roller unit is provided with following cylinder completely.Cylinder advantageously is equipped with level and smooth periphery under this, and described level and smooth periphery has high coefficient of friction to fiber at least in the traveling zone of fiber band.This for example by in the traveling zone of fiber band, chemically or electrolytically handle at least or coating under the periphery of cylinder reach.For example in the traveling zone of fiber band, use the periphery of cylinder under nickel-diamond coating at least.Correspondingly the following cylinder of Gou Chenging can also be provided as spare part separately.
Described compression member is the parts based on the of the present invention thought identical with the compression roller unit of stretching-machine according to the present invention or stretching-machine, and is protected independently.Compression member described herein preferably has the body of the prismatic in fact of triangular-section roughly.The formation of the prismatic of described general triangular is considered output press roll and is provided the shape in the gap between the pressure roller.The radius of the supporting surface of compression member is the following cylinder of balanced support and the radius that provides roller of stretching-machine to a great extent.Magnet under arrangement handlebar compression member is fixed in the body of compression member on the cylinder.Magnet described herein can be directly outstanding from the supporting surface towards following cylinder, and constitute its part.Yet described magnet but can also be placed near the holding in the bore hole of supporting surface.For the reason of wearing and tearing, and because its favourable machinability and DIMENSIONAL STABILITY, described compression member is made of ceramic material or plastics-ceramic mixture.

The specific embodiment
Stretching-machine by the known annular spinning machine of prior art schematically is shown in Fig. 1, and described stretching-machine indicates with label 101 generally.Stretching-machine 101 is fully known from prior art, constitutes so-called three cylindrical stretching-machine.It comprises one, and to draw in roller right, and the described roller of drawing in is to there being drawing in pressure roller 102 and drawing in lower roll 103 of feed-in fiber band F.The intermediate calender rolls of pressure roller 104 and middle lower roll 105 is right in the middle of being connected with along the direction of transfer of fiber band F, by this roller to guiding two belts 106.Draw in roller to 102,103 and intermediate calender rolls define the predraft district 107 of fiber band F between to 104,105.Output arrangement at the three cylindrical stretching-machine has the outlet roller of output press roll 108 and output lower roll 109 right.Intermediate calender rolls to 104,105 and the highway section of outlet roller between to 108,109 constitute main drawing zone 110, fiber band F is stretched becomes desired fineness therein.
The fiber band F that has stretched withdraws from stretching-machine 101 at outlet roller to 108,109 clamping line A.This fiber band F twists with the fingers by means of spinning rotation R becomes the finished product yarn, with on the outlet roller of stretching-machine 101 interface, constitute so-called spinning triangle to 108,109 clamping line A, the yarn that is provided by stretching-machine in described spinning triangle draws in together and integrates becomes the knot structure.In order to take in all fibers in the yarn as much as possible and to make all fibers be subjected to the pretension of identical as far as possible size when twisted, people keep the spinning triangle as much as possible for a short time hardy.The fiber band F that stretches and widened is drawn in again together and encrypts before the twisted resultant yarn for this reason.Before outlet roller is to 108,109, arrange compression member 111, by this compression member 111 guiding fiber band F for this reason.The conpressed fibers band F of construction geometry by compression member 111-mechanically thus.
Fig. 2 illustrates the example of a compression member 111, and described compression member has the shape of anvil piece sample in fact.Described compression member 111 is provided with the compression tank circuit 112 on the side of fiber band in its use location, the described compression tank circuit 112 is passed in fiber band F guiding.The compression tank circuit 112 is that some funnel-like expansion ground constitutes at it on the face amount 114 of the fiber band that arrives, and the outlet on opposite side is tapered into desirable diameter.The exit width of the tank circuit has determined which type of yarn scope is compression member 111 be applicable to.
The shortcoming of this known arrangement has illustrated and has illustrated clear again with reference to Fig. 1 in this paper beginning place.In the arrangement in compression member 111 is located at the main drawing zone 110 of stretching-machine 101, between the stretching belt 106 that is located at main drawing zone 110 and outlet roller are to 108,109, side by side carry out stretching and the compression of fiber band F basically.Disturbed drawing of fiber band F equably thus.In order to create the position of compression member 111, strengthened outlet roller to 108,109 clamping line A and distance between the stretching belt 106.But also strengthened the distance that does not guide fiber band F betwixt thus.The increasing of the distance that is interfered and returns with must not guiding fiber band F of evenly stretching can cause the inhomogeneities of yarn, and this has influenced its quality.Compression member 111 is noisy when operation stretching-machine 101, and loses easily owing to its little structure.
Fig. 3 schematically illustrates a stretching-machine that constitutes according to the present invention, and it indicates with label 1 generally.Stretching-machine 1 relates to the three cylindrical stretching-machine, yet has revised in conclusive scope.Predraft district 7 is still right to the roller that has pressure roller 4 and middle lower roll 5 from the entrance extension that has input pressure roller 2 and input lower roll 3.By the two belts 6 of intermediate calender rolls to the main drawing zone 10 of 4,5 guiding.Main drawing zone 10 extends to output press roll 8 from intermediate calender rolls to 4,5, and described output press roll 8 rests on down on the cylinder 9.Output press roll 8 defines output clamping line A with the contact area of following cylinder 9.
With the stretching-machine of known three cylindrical differently, following cylinder 9 has the diameter bigger than common output lower roll.Make it possibility thus, arrange one and provide pressure roller 15 in the connector of output press roll 8, the described pressure roller that provides similarly rests on down on the cylinder 9.Providing contact area between pressure roller 15 and the following cylinder 9 has defined and has provided clamping line B.At output press roll 8 with provide zone between the pressure roller 15, specifically be meant in output clamping line A and the zone of giving between the outlet B formation compressional zone 16.In compressional zone 16, arrange one to have the compression member 11 that the relative prior art parts that compress the tank circuit 12 have been revised.Described compression member 11 because its structure and how much-mechanically act on and pass the fiber band F that the compression tank circuit 12 guiding ground have been widened.Compression member 11 preferably seamlessly rests on down on the cylinder 9 and against providing pressure roller 15.Propping up by face of 11 pairs of following cylinders 9 of compression member is configured in this wise at this: its radius equates with the radius of the following cylinder 9 that supports basically.Prevent that thus fiber from arriving at propping up by between face and the following cylinder 9 of compression member 11.The size of the longitudinal extension of the supporting surface of the following cylinder 9 of Que Dinging like this makes it to stop providing clamping line B precontract 3mm to 8mm.Preventing thus that compression member 11 is stuck in provides between pressure roller 15 and the following cylinder 9.The supporting surface that 11 pairs of compression member provide pressure roller 15 also to a large extent balance provide the periphery of pressure roller 15.Especially in this wise constitute described supporting surface: make described support carry out perpendicular to stretching-machine in fact.Compressor reducer does not contact and provides pressure roller 15 in the zone of leading to the clamping line.Arrange compression member 11 in this wise: make it not contact with output press roll 8 normal in service.Compression member 11 is at output press roll 8 and provide the formation that the cross section on the top, minimum range zone between the pressure roller 15 enlarges.Reach thus, compression member 11 for example can be lifted from following cylinder 9 in short time with providing pressure roller 15 when needed, enables to proceed in compressional zone 16 R that reverses of yarn.
In constricted zone shown in Figure 4 16, compression member 21 is at output press roll 8 and provide the cross section 23 of extending on the top, minimum range zone between the pressure roller 15 and be provided with convex shoulder 25 projection in other words, described convex shoulder 25 projection overlap joint in other words provides the face amount of pressure roller 15, and thus compression member 21 is provided pressure roller 15 relatively and axially only fix with very little gap.Compressional zone 16 still extends to from output clamping line A and provides clamping line B, and described clamping line is by corresponding roller 8 and 15 definite with the contact area of following cylinder 9.Fiber band is supported by the compressional zone 16 of cylinder 9 along whole road.The compression tank circuit of compression member 21 indicates with label 22.In the drawings as can be seen, the described compression tank circuit 22 is gradually thin along the direction that provides pressure roller 15 from the side towards output press roll 8.
Fig. 5 illustrate compression member 21 in the use location view towards the recessed bent volume side 24 of the fiber band of sending.The compression tank circuit 22 has obvious cross section greater than opposed outlet side on volume side 24.The cross section, top of compression member 21 still indicates with label 23.Convex shoulder on the longitudinal side of compression member 21 projection in other words indicates with 25.At the convex shoulder 25 coloured mark on the projection in other words, can play the indicator in the cross section of the compression tank circuit 22.The user can directly read the yarn what scope compressor reducer 21 is applicable to thus.Compression member 21 can use plastics in fact, with ceramic material or metal, for example make with steel or its mixture.Be illustrated in the permanent magnet that in service and following cylinder cooperates with label 26.Guarantee that thus compression member 21 also can seamlessly abut on the following cylinder and not mention a little, and guarantees that fiber can not arrive between the cover of compression member 21 and following cylinder 9 when machinery is swung.Two permanent magnets 26 shown in Figure 5.Obviously, can also in compression member, only pack into a permanent magnet or a plurality of permanent magnet.
Fig. 6 illustrates the compressional zone 16 of the curved conveying path that has a fiber band, described transfer path from the output clamping line A of output press roll 8 and following cylinder 9 extend to provide pressure roller 15 and following cylinder 9 provide clamping line B.Preposition drawing zone is delineated out by two belts 6.In the length 1 of this transfer path AB about 1/3rd length less than the fiber that is incorporated into fiber band.Can draft, the length 1 of transfer path AB changes by the position that adjusting provides pressure roller 15.Delineate out compression member 31 between two two pressure rollers 8,15 that rest on the following cylinder 9, its compression tank circuit 32 constitutes towards following cylinder 9 openly.Can see clearly in this diagram, the inlet of the compression tank circuit 32 is having near compress the tank circuit 32 pressure roller 15 than providing the big cross section of meet near the output press roll 8.Compression member 31 seamlessly is pressed in down on the periphery of cylinder 9.Or this is by the deadweight of compression member 31, by the prestressing force of machinery, for example by loading spring or analog, perhaps reaches by the polarity between compression member 31 and following cylinder 9.Also can draft the combination of these measures of employing.
In order to prevent that fiber from arriving at down cylinder 9 uncontrollably and play between the compression member 31 of how much-mechanically effect, if down the periphery of cylinder 9 is not by interruption, disconnection or analog ground and be level and smooth suiting to a great extent.Utilize described level and smooth circumferential surface, compression member 31 closely contacts with described periphery and fiber is merely able to arrive in the compression tank circuit 32.Adopt level and smooth following cylinder 9 for drawing of fiber band F is immaculate equably, because the fiber that twice ground clamping successively come out from drawing zone.On the output of drawing zone, also do not reach whole peripheral speeds of cylinder 9 down, fiber that is to say providing B on the clamping line that promptly 16 output obtains this peripheral speed in the compressional zone laterly on clamping line A.Act on its length thus greater than the little tension force on those fibers of the transmission highway section AB length L of passing through compressional zone 16, play longitudinally to support compression member 31 in an advantageous manner.
Under constituting smoothly during the periphery 91 of cylinder 9, the fact shows, if down the periphery 91 of cylinder 9 to have the higher coefficient of friction of fiber in the traveling zone of fiber band F at least be favourable.This for example can be on the periphery of cylinder at least in the traveling zone at fiber band, and coating reaches by chemically or electrolytically handling in other words.For example the periphery at following cylinder is provided with nickel-diamond coating in the traveling zone at fiber band at least.The arrow that indicates with R is still represented to spin twisted, and the handle of using stretches and the fiber band F that compressed again is spun into the finished product yarn.
