Description

A kind of twister of two-for-one twister and the two-for-one twister using the twister

Technical field

The utility model belongs to field of textile equipment, more particularly, to a kind of two-for-one twister (double-twist twisting Machine twister (twisting device)), and use the two-for-one twister of the twister.

Background technology

Textile industry is generally required for carrying out single-strand yarn twisting processing, twisting before being weaved using yarn (twisting) it is to be twisted together into strand in order to which the single-strand yarn of two or more than two is wound.Method, every to spin in a broad sense During yarn, sliver (yarn, yarn, line, silk) is reversed rubbing or axially winding around its axis, sliver is obtained " turn " Or looping referred to as " is twisted ".Twisting can make between fiber and fiber or will not after mutual obvolvent or entanglement between monofilament and monofilament Loose or slippage, and with certain physical-mechanical properties（Such as intensity, elongation, elasticity）And external appearance characteristic（As gloss, filoplume, Feel etc.）.Main twisting equipment is " two-for-one twister " at present, two-for-one twister title from included by it can to feeding and Row multi cord realizes spindle (spindle) device of " one turn of two sth. made by twisting ".Traditional two-for-one twister typically all there is the spindle to twist Device and to being twisted after multi cord actively draw and be wound into the coiler device of multiply spool.

As shown in figure 1, and refer to Fig. 3 and Fig. 2, traditional twisting process is divided into " doubling " and " twisting " two procedures, institute Call " doubling ", " shown in the part of process one ", that is, by the merger of single cord 2 from different sub-thread spools 1 for simultaneously of such as Fig. 1 Row multi cord 3 and it is allowed to be wound into parallel multiply spool 4.Its principle is very simple, only all single cords 2 need to be allowed to pass through together Then one common passage is directly wound into parallel multiply spool 4；The parallel conduct of multiply spool 4 of output after doubling In the raw material of lower " twisting " process together, such as Fig. 1 " shown in the part of process two ", generally will be parallel in parallel multiply spool 4 Multi cord 3 feeds so-called " spindle (spindle) " device and carries out generation twisting multi cord 5 after rotation twisting, then passes through winding The twisting multi cord 5 added after " turn " is wound into twisting multiply spool 6 and just completes twisting process by device.Fig. 3 displayings It is the principle how traditional " spindle " device to parallel multi cord 3 rotate twisting, as shown in figure 3, parallel multiply spool 4 Insert on the hollow spindle 7 of the inner cylinder of hollow ingot tank 701 of spindle device, the cylindrical hollow spindle 7 and institute The perforate for stating the bottom center of hollow ingot tank 701 is communicated, and the hollow ingot tank 701 is sleeved on by the perforate of its bottom center On one twisting plate 8 of the lower section of hollow ingot tank 701, the parallel multi cord 3 extracted out from parallel multiply spool 4 initially enters described The inside of hollow spindle 7, is then folded into an interconnection 802 inside the twisting plate 8, so-called here " horizontal Passage " refers to there is a folder between the interconnection 802 and the inner passage of the hollow spindle 7 as shown in Figure 3 Angle, the usual angle is 90 degree of right angles；The bottom part down of twisting plate 8 center has as shown in Figure 3 is fastened as a whole with it The power transmission shaft 803 of common axial line, the twisting plate 8 is installed on twisting disc carrier 11 and can be free around Pivot Point Center line Rotation, the power transmission shaft 803 and transmission belt 10（Namely " tengential belt " being commonly called as）Fit and in the frictional drive of the transmission belt 10 （It is exactly the direction of motion of tengential belt shown in bottom solid black straight arrow in Fig. 3）Rotated under driving and then drive twisting Disk 8 carries out lasting rotation（As shown in the solid black curved arrow of the both sides of twisting plate 8 in Fig. 3）, the usual twisting plate 8 The axial line of shaft center line and the inner passage of hollow spindle 7 is in same rectilinear direction, and such as Fig. 3 upper right corner is put Among big region shown in vertical chain-dotted line；As shown in figure 3, the multiply exported from the interconnection 802 described in the inside of twisting plate 8 Line will draw upward motion by the coiler device above the spindle device（As shown in the single lined arrows of the top in Fig. 3）, In order to which the Fig. 3 that saves space is eliminated, textile industry is general to be commonly called as " roller "（Namely the transliteration of English " Roller "）And its it is supporting The yarn take-up device of rubber roller and the horizontal feed carrier for forming regular profile yarn bobbin；Due to the spindle device Traction of the coiler device of top to multi cord causes multi cord to there is axial pulling force, and because the twisting plate 8 everywhere The inner passage of interior interconnection 802 and the hollow spindle 7 is not in same rectilinear direction, such as putting for Fig. 3 upper right corner Big figure is shown and refers to Fig. 2, and multi cord will be sent out when entering the interconnection in the twisting plate 8 inside hollow spindle 7 Life bends and can be closely against at the bending 801 in twisting plate 8, because the axial direction of the multi cord of both sides at bending 801 is drawn Power（As shown in two single lined arrows in Fig. 2）Make a concerted effort the position of bending 801 will be pressed, thus twisting plate The position of bending 801 will produce corresponding reaction force to multi cord, and one can be produced to multi cord equivalent to the bending 801 Radial clamping force, as shown in the black arrows in Fig. 2.At that time because the twisting plate 8 is in the drive of lower section transmission belt 10 Under axial line and the axial line of twisting plate 8 ceaselessly around the inner passage of hollow spindle 7 rotated, thus such as figure The twisting plate 8 shown in 3 rotation can with cause the multi cord in the inner passage of hollow spindle 7 be twisted generation sth. made by twisting Return, actually this twisting process equivalent to pinched with finger the multi cord at bending 801 and be allowed to rotation so as to allow top Multi cord formation turn in hollow spindle 7；As shown in figure 3, enter after bypassing the position of bending 801 due to multi cord again The interconnection 802 of the twisting plate 8, thus with the rotation of twisting plate 8, it is many in the interconnection 802 of the twisting plate 8 Strand can be also twisted；Accompanying drawing mark has been used in order to distinguish in the multi cord being twisted before and after the position of bending 801, Fig. 3 Remember 501 to mark the multi cord being twisted in the position foregoing description hollow spindle 7 of bending 801, and in this manual will It is named as " preceding twisting multi cord ", while marking the transverse direction after the position of bending 801 to lead to using reference 502 The multi cord twisted again in road 802, is named as " twisting multi cord afterwards " among this specification；In this specification In, the multi cord at every multi cord rotation clamping position since the feeding position of feeding twister to twister all claims " preceding twisting multi cord " and to be marked with reference 501 in Figure of description, it is every from twister Multi cord rotation, which clamps position and exported to the multi cord of coiler device, is all referred to as " twisting multi cord afterwards " and with reference 502 It is marked in Figure of description.In summary, will be simultaneously many to the preceding twisting when twisting plate 8 rotates a circle Strand 501 and rear twisting multi cord 502 implement twisting operation, namely include hollow spindle 7, twisting plate 8 and hollow ingot to feeding The multi cord of spindle device including tank realizes " one turn two is twisted with the fingers (one turn, double twist) ", and this is two-for-one twister title The origin of central " double twisting (double twist) " two words.

Carry out the weak point of the spindle device of analysis conventional referring next to Fig. 3 and Fig. 2, firstly, since feeding the sky The multi cord of heart spindle 7 generates bending after the twisting plate 8 is entered, and the preceding part of twisting multi cord 501 of multi cord can It is located at regarding as on the shaft center line direction of the twisting plate 8, and the rear part of twisting multi cord 502 of multi cord does not have position In will certainly just produce rotation on the shaft center line direction of the twisting plate 8, and once rotating will produce with windage Unnecessary energy resource consumption.As shown in figure 3, the rear twisting multi cord 502 exported from the interconnection 802 of twisting plate 8（In Fig. 3 Multi cord 502 is twisted after a part to eliminate helix pattern and schematically show with double dot dash line）The twisting will be surrounded The shaft center line of disk 8（Namely the axial line of hollow spindle 7）Rotated, produce hollow single line curved arrow institute in the middle part of Fig. 3 The interconnection 802 from the twisting plate 8 shown be exported to coiler device before collection wire loop 23 between one be commonly called as " gas The revolution of circle ", the air ring 9 centered on the shaft center line of the twisting plate 8 around whole multiply spool 4 parallel and Its container hollow ingot tank 701, it is bulky, add the speed of rotation again quickly, therefore by resistance larger between generation and air Power can consume the power of coiler device in vain, and the air ring 9 of exposure outside encounters barrier and can be easy to interrupt the rear twisting Multi cord 502.In addition, the multi cord into the spindle device is actually by multi cord bending part and closely against place The frictional force that produces prevents the radial direction of the single cord among multiply wire harness from overturning in conjunction with rotation under radial clamping force effect To realize twisting, therefore it is often outstanding inadequate to rely solely on the frictional force that right-angle bending is produced at one, easily produces bending part The radial direction upset influence twisting effect of position multi cord, serious is even unable to reach predetermined turn quantity, actually namely Because traditional spindle device is caused to the position that multi cord implements to rotate twisting operation to the radial clamping force deficiency of multi cord 's.

The content of the invention

The deficiency for the traditional spindle twisting device pointed out, one kind that the utility model is provided are saved for above-mentioned background technology one Twister can not only cause after feeding the multi cord of the twister and being twisted from many of twister output Strand is located at same rectilinear direction as far as possible, so that the generation of " air ring " is avoided to reduce power consumption, and can be more effective Ensure the twisting operation of " one turn two sth. made by twisting ", will not be because the radial clamping force to multi cord is not enough and make the twisting journey of multi cord Degree is given a discount.

The weak point that the rotation of following compares figure 2 and combination Fig. 3 to traditional spindle device is twisted further is divided Analysis.As shown in Fig. 2 and refer to Fig. 3, the multi cord of the traditional spindle device of feeding can all turn in one among a spindle device Roll over the inwall of 801 positions and the position closely against and produce bending, because the two-for-one twister using spindle device can all be equipped with receipts Collect the coiler device of the multi cord after twisting, therefore the multi cord of feeding spindle device can be led by a lasting axial direction all the time Gravitation, the axial thrust force can form the axial tension of two different directions on multi cord bending part both sides（Such as two in Fig. 2 Shown in single lined arrows）, making a concerted effort for this two pulling force will be to the spindle device of multi cord bending position（Such as oblique hatching in Fig. 2 Shown region）Formed and extruded, and the reaction force that spindle device is made a concerted effort to this（As shown in black arrows in Fig. 2）Will shape Into a radial load that radial compression is carried out to multi cord.Spindle device enters around the shaft center line shown in Fig. 2 chain lines After row rotation（As shown in the hollow curved arrow in Fig. 2）, because multi cord is actually formed in the radial load that bending part is subject to One clamping force to multi cord radial direction, is rotated equivalent to the bending part that multi cord has been pinched with finger, therefore just Twisting operation can be implemented to multi cord.As previously described and refer to Fig. 3, the rotary motion of spindle device is in fact rolled over to multi cord Turn of bilge position both sides part simultaneously implement twisting operation, form feeding end to bending part preceding twisting multi cord 501 and The rear twisting multi cord 502 that bending part sets out, thus achieves the double twisting effect of so-called " one turn of two sth. made by twisting ".As shown in Fig. 2 simultaneously With reference to Fig. 3, due to need using multi cord closely against bending part formed one make a concerted effort with produce a reaction force come Serve as radial clamping force, therefore the preceding part of twisting multi cord 501 and the rear twisting multi cord 502 of the traditional spindle device twisting of feeding There certainly will be an angle between part, namely can not twist multi cord 501 so preceding in same rectilinear direction and twist afterwards Multi cord 502 is impossible to be located in same rectilinear direction in traditional spindle device, is also impossible to be entirely located in spindle In the shaft center line of device, therefore some sections of multi cord are inherently rotated around the shaft center line, also The generation of " air ring " can not be avoided.With reference to Fig. 3, in traditional spindle device, because the flexibility of multi cord can be easily It is artificial that preceding twisting multi cord 501 is limited in the shaft center line of spindle device, but twisting multi cord 502 is impossible to afterwards It is also defined among traditional spindle device in the shaft center line, as shown in Figures 2 and 3, due to rear twisting multi cord 502 on shaft center line direction, therefore will inevitably form air ring 9 with the rotation of spindle device.It is double among Fig. 2 The different angle orientations that namely twisting multi cord 502 is located at during rotation forms air ring 9 afterwards of chain-dotted line signal.And And in order to be able to produce sufficiently large radial clamping force to ensure to twist effect, the degree of multi cord bending can not be too small, Ye Jiqian The angle twisted between multi cord 501 and rear twisting multi cord 502 is small as far as possible, so can then be formed than larger conjunction Power serves as radial clamping force to produce sufficiently large reaction force, and otherwise multi cord will just be easy to overturn shadow in bending part The effect of twisting is rung, therefore rear twisting multi cord 502 and the drift angle of the shaft center line are general all without too small, so being formed The scale of construction scale of air ring 9 be also impossible to very little.And with the increasing of multi cord bending degree, multi cord bending part and ingot Active force between sub-device is also increased therewith, the cunning of the axial slip suffered by bending part of the multi cord among Fig. 2 and Fig. 3 Kinetic frictional resistances can also increase therewith, so will certainly then cause follow-up coiler device traction to collect the meaningless of the power of multi cord Consumption.

In summary, based on rational analysis above, it can learn that a practical twister has to possess to many Strand implements the ability persistently rotated after radial clamping.Compared to traditional spindle device, one kind that the utility model is provided adds The twist device creative revolving part using sustainable rotation serves as the clamping device of multi cord, comes in conjunction with the rotation of itself Twisting is efficiently realized, but also can largely ensure the effect of twisting.Come using the revolving part of sustainable autobiography The largest benefit for serving as the clamping device of multi cord is as multi cord continues under the coiler device traction drive of two-for-one twister Advance, clamping the revolving part of multi cord can avoid producing sliding friction with the multi cord in advancing by transferring certainly.In addition, this A kind of twister that utility model is provided may also be ensured that feeding and the multi cord exported as far as possible in same rectilinear direction, And press close to or even be completely superposed as far as possible with the shaft center line of the rotation twisting operation of twister, avoided with this by " air ring " The power consumption that the caused unhelpful friction with air is produced.

As shown in Figure 10, and Fig. 2 is referred to, the utility model mainly ensures to apply multi cord using two technical measures The sufficiently large radial clamping force, one is increase multi cord on revolving part with revolving part directly or indirectly closely against The quantity at position is wound, accumulates to form sufficiently large radial clamping force with this, " first ", " second ", " third " among such as Figure 10, Technical measures shown in " fourth " and " penta " subgraph；The second is using revolving part and multi cord closely against directly being applied to multi cord Plus radial pressure serves as the radial clamping force needed for rotation twisting operation, " oneself ", " heptan ", " pungent " and " nonyl " among such as Figure 10 Subgraph.Notice that reference is all inside revolving part, revolving part for 24,1607,1608,22 and 2202 part among Figure 10 Single line curved arrow all indicates the rotation for the corresponding reduction sliding friction that revolving part occurs with the traveling of multi cord, heavy black line Represent the multi cord of feeding twister, vertical chain-dotted line and hollow curved arrow signal shaft center line（Each width subgraph is worked as In all revolving parts all can synchronize rotation around the shaft center line together）, the thick filled arrows reference pair of black The radial clamping force that multi cord is produced.

A kind of principle of technical solutions of the utility model as shown in " first ", " second " subgraph among Figure 10, feeds this reality It can be wound with the multi cord of the twister of new offer on a revolving part 24 of twister defeated after at least one circle Go out, while the revolving part 24 is persistently rotated around the direction shown in figure chain lines and hollow curved arrow, due to defeated Coiler device that the multi cord gone out typically can be all equipped with by two-for-one twister is drawn, so multi cord all can be closely against in rotation Realize and closely wind on part 24, it is the same equivalent to being bundled on revolving part 24, so as to reliably be realized very much footpath To clamping, then just can be while to the preceding twisting multi cord 501 and rear twisting multi cord of multi cord along with the rotation of revolving part 24 Twisting operation is implemented in 502 parts simultaneously, and the double twisting effect of " one turn of two sth. made by twisting " of traditional spindle device so can be then realized completely. Next analysis multi cord winds the origin of the radial clamping force produced during at least one circle on revolving part 24, uses as previously described The two-for-one twister of twister typically can all be equipped with the coiler device for collecting multi cord after twisting, therefore Figure 10 " first ", " second " son Rear twisting multi cord 502 among the figure of figure two is by persistently by the axial tension from coiler device, this axial tension can also be passed All multi cord parts including preceding twisting multi cord 501 are directed at, with the folding inside traditional spindle device for analyzing above The principle that radial clamping force is produced at curved 801 is the same, and the part that multi cord wrapped around revolving part 24 will be everywhere by such as Figure 10 " first ", " second " two subgraph among one it is whole circle black arrows array shown in continuous radial clamping force because very aobvious Right each position of multi cord on revolving part 24 equivalent to have one closely against bending, bending as previously described The axial tension of both sides make a concerted effort can be formed one put on revolving part 24 make a concerted effort, should make a concerted effort reaction force act as To the radial clamping force of multi cord.Compared to traditional spindle device as described above, multi cord is allowed on a revolving part 24 The technical scheme exported again after the circle of winding at least one considerably increases the region for producing and carrying out radial clamping force, because Figure 10 360 degree of whole circle bending region length shown in " first ", " second " two subgraph are several times as much as no more than 90 degree shown in Fig. 2 and Fig. 3 The length of bending region, not to mention multi cord winds the situation of multi-turn on revolving part 24, so then causes composition multi cord Single cord winding position radial direction upset be almost unlikely to occur, be effectively ensured twister rotation twisting it is reliable Property.And because multi cord is wound on the outer surface of revolving part 24, its axial tension can not possibly be by the rotary shaft of revolving part 24 The heart, thus revolving part 24 is also very easy to the traveling generation rotation with multi cord, will not cause too big to the traveling of multi cord Obstruction.Revolving part 24 is allowed to be equipped with high-efficiency rotating measures for reducing wear as such as ball bearing if taking, it is possible to very big The sliding friction produced among traditional spindle device is avoided in degree.Notice that " first ", " second " two subgraph among Figure 10 is drilled respectively The shaft center line and preceding twisting multi cord 501 and the rear different journeys for twisting multi cord 502 of the revolving part 24 of twister are shown The registration of degree, the shaft center line represented with chain-dotted line and hollow curved arrow shown in " second " subgraph of true figure 10 above is complete It can be overlaped entirely with the projection of preceding twisting multi cord 501 and rear twisting 502.Compared to traditional spindle as described above Twister, even if the situation that the multi cord as shown in Figure 10 " first " subgraph is less overlapped with shaft center line, due to rotation The diameter of part 24 can not possibly be very big（Because the basic nothing of the scale of construction of revolving part 24 requires more than aforementioned hollow ingot tank 701）, therefore institute's shape Into air ring the scale of construction can be described as it is very little, do not result in as traditional spindle device more than kinetic equation loss.In fact Because the multi cord as shown in " first ", " second " two subgraph has wound at least one whole circle on revolving part 24, the feelings of a whole circle are being wound It can be allowed completely as shown in " second " subgraph under condition and feed the preceding twisting multi cord 501 of twister and the rear twisting multi cord of output Shaft center line as far as possible with revolving part 24 is overlapped, it is possible thereby to which largely reducing multi cord surrounds shaft center line Produce unnecessary rotation and form air ring.If in order to ensure the effect of twisting, multi cord can be also allowed completely in revolving part A more than circle is wound on 24, so then by radial clamping force of the generation at double to multi cord, it is ensured that " one turn two of twister The target of sth. made by twisting ".It is compared to the spindle twisting device of aforementioned conventional, the technical scheme of Figure 10 " first ", " second " two subgraph displaying It may be said that both several times increase the radial clamping force needed for twisting multi cord, and multi cord can be easily allowed to be applied in rotation Overlapped as far as possible with shaft center line so as to effectively avoid the generation of this highly energy-consuming phenomenon of air ring when turning twisting operation, and And the rolling of revolving part 24 also considerably reduces the resistance of multi cord traveling, it may be said that be killing three birds with one stone！Figure 10 " third " son Figure shows that twister of the present utility model includes two revolving parts and multi cord the winding part on two revolving parts A kind of principle of technical scheme of region rather than a whole circle.Two revolving parts shown in figure can surround chain-dotted line and sky simultaneously Shaft center line shown in heart curved arrow is rotated, similar with foregoing " first ", " second " two subgraph, the displaying of " third " subgraph A kind of technical scheme principle of the present utility model has also been provided simultaneously with clamping can apply rotation with rotating the two to multi cord The key element of twisting operation, so can also effectively realize rotation twisting.Enclosed very compared to winding one is whole on a revolving part Or more circle, the radial clamping force to multi cord that technical scheme shown in " third " subgraph is produced can be smaller, because multi cord Wrapping range with rotary portion region closely against formation will lack relative to whole circle, and preceding twisting multi cord 501 With rear twisting multi cord 502 can not well with " third " subgraph chain lines and shown in hollow curved arrow shaft center line phase Overlap, but coiler device can with relatively easy traction multi cord thus consume slightly few power, and multi cord and rotation The degree that axial line deviates is actually also much smaller than traditional spindle device, because the profile of revolving part 24 will not be very as previously described Greatly.Multi cord can be allowed winding one is whole on a revolving part wherein completely by noting the twister of Figure 10 " third " subgraph displaying Circle even multi-turn and then wound another revolving part again, or even all wound on two revolving parts an at least circle, so then before Twisting multi cord 501 and rear twisting multi cord can be very good to coincide with shaft center line.In addition, any one revolving part is all The size of non-whole circle wrapping range can be adjusted by adjusting the means of its installation site in twister, so as to The adjustment of opposite fine for example allows the revolving part 24 of the central lower section of " third " subgraph remote to the right the radial clamping force of multi cord Direction movement from shaft center line can just increase multi cord in wrapping range thereon, so as to increase the radial direction to multi cord Clamping force, it is on the contrary then can accordingly reduce radial clamping force.

Figure 10 " fourth ", " penta " two subgraph shows that twister of the present utility model uses three or even more than three Revolving part technical scheme principle, three shown in each subgraph or even four revolving parts can all surround dot-dash simultaneously Shaft center line shown in line and hollow camber line arrow rotates together.As shown in " fourth ", " penta " two subgraph, three or even three are used The individual part that rotates above is advantageous in that can relatively easily adjust preceding twisting multi cord 501 and rear twisting multi cord 502 exists respectively Feeding orientation and output orientation on the revolving part and last revolving part wound of first winding, so that twisting is more before making Strand 501 and rear twisting multi cord 502 are fully located at same rectilinear direction as far as possible, when this rectilinear direction and rotation twisting behaviour The shaft center line of work can almost can just avoid producing because multi cord deviates shaft center line direction completely when highly overlapping Raw " air ring " phenomenon.In addition, it is similar with the principle for the technical scheme that earlier figures 10 " the third " subgraph is shown, using three or even three The individual technical scheme for rotating above part can also convert multi cord winding area conveniently by the installation site of adjustment revolving part The size in domain and then fine adjustment for example allow rotation among " fourth " subgraph in the middle part of the rightmost side to the radial clamping force of multi cord Turn part and move its installation site to the shaft center line direction on the left of it can just to reduce multi cord in wrapping range thereon, from And reduce to the radial clamping force of multi cord, reversely adjust its position and then increase radial clamping force to multi cord.It is noted that Although being that " fourth ", " penta " two subgraph show only the situation of three and four revolving parts, as long as the actually tension of multi cord Intensity sets more synchronous enough, then between the revolving part of first winding of multi cord and the revolving part of last winding The winding of revolving part formation multi cord " hundred turns thousand times " also without can not, and winding of the multi cord on revolving part completely can also It is a whole circle even multi-turn, it is numerous.

From it is foregoing to allow multi cord bending winding on revolving part to produce radial clamping force different, " oneself " among Figure 10, " heptan " two subgraph shows the utility model using revolving part to directly applying radially closely against multi cord thereon A kind of principle of the technical scheme of clamping force, shown in " oneself ", " heptan " two subgraph such as Figure 10, what feeding the utility model was provided adds The multi cord of twist device can be constantly in straight trip direction without occurring any bending, two from feeding to output（A pair）Or it is many Multi cord is clamped to revolving part from the both sides of multi cord direct of travel to apply it such as solid black arrow in " oneself ", " heptan " two subgraph Radial clamping force shown in head, " oneself ", all revolving parts among " heptan " two subgraph all can synchronously surround shaft center line simultaneously Rotated to twist twisting multi cord 501 and rear twisting multi cord 502 before multi cord is formed.Because the flexibility of multi cord is complete Multi cord straight trip can be allowed by two revolving parts closely against place, the interior public affairs that need to only allow multi cord to be located at two revolving parts are cut Line direction, or perhaps order clamps the plane of the shaft center line composition of two revolving parts of multi cord perpendicular to multi cord traveling Direction can make multi cord be always positioned at same linear direction of travel without produce bending, when institute in " oneself ", " heptan " two subgraph The synchronous rotary axial line for having revolving part can just avoid the generation of air ring phenomenon completely when being overlapped with multi cord, and due to rotation All with the traveling of multi cord corresponding rotation can occur for part（As shown in single line curved arrow in " oneself ", " heptan " two subgraph）So as to big Sliding friction is reduced greatly, so " oneself ", the principle of the technical solutions of the utility model of " heptan " two subgraph displaying are compared to foregoing " first ", " second ", " third ", " fourth ", the technical principle of " penta " each subgraph displaying can preferably reduce the resistance of multi cord traveling, reduce The power consumption of coiler device.As long as in addition, each pair revolving part is sufficiently large to the clamping force of multi cord can just to prevent group completely Radial direction upset into the single cord of multi cord is so that it is guaranteed that the effect of twisting, this, which says, also easily accomplishes, and for example reduction is revolved Turn the gap between part or the revolving part using elastic material and revolving part is mutually extruded clamping multi cord, then or with The elastic force of elastomer, the magnetic force of magnetisable material force two revolving parts of clamping multi cord to keep persistently being close to state etc., phase Than the radial clamping force generated indirectly in the axial tension using multi cord and its bending, revolving part is allowed directly to be carried out to multi cord The direct radial clamping force that radially pressure is produced is more much bigger than the foregoing radial clamping force generated indirectly, so as to more have Effect ground ensures the effect of rotation twisting.Figure 10 " heptan " subgraph compared to " oneself " subgraph be more a pair of clamping multi cord rotation It is sufficiently large to the radial clamping force of multi cord to ensure to turn part.Note so far Figure 10 " first ", " second ", " third ", " fourth ", Clamping mode shown in " penta ", " oneself ", " heptan " subgraph or even above based on the description of above-mentioned subgraph can also be carried out arbitrarily completely Independent assortment, for example first allows multi cord to wind a circle on a revolving part again by clamping of a pair of revolving parts etc., no One and foot, come under the utility model offer technical scheme principle category in.

" pungent " subgraph in Figure 10 shows the technology original with reference to the foregoing two kinds of generations radial clamping force of the utility model A kind of principle of technical scheme of generation is managed, as shown in Figure 10 " pungent " subgraph, two pairs of revolving parts held tight multiply at a slant Line, the so-called planar tilt being made up of its rotation axial line for referring to each pair revolving part that tilts is in the rotation of rotation twisting here Axial line, namely " pungent " subgraph chain lines and the shaft center line indicated by hollow curved arrow；Simultaneously because feeding is more Strand and the multi cord of output are all located on shaft center line direction as far as possible, therefore multi cord can all occur tightly on revolving part The closely connected bending leaned on.Clamping multi cord not only can be produced directly as tilted the solid heart of black in figure to multi cord pressure at a slant To the direct radial clamping force of multi cord shown in arrow, it can also be generated such as indirectly using winding of the multi cord on revolving part Radial clamping force shown in solid black block arrow slightly smaller in all horizontal directions among " pungent " subgraph.It is compared to foregoing The technical principle of " oneself ", " heptan " two subgraph displaying, " pungent " subgraph is shown with foregoing " first ", " second ", " third ", " fourth ", " penta " subgraph Allow multi cord to occur winding is similar, the traveling to multi cord that can also suitably produces some and damped, so that it is guaranteed that to multiply The twisting effect of the preceding twisting multi cord 501 of line, the traveling damping for actually adding some multi cords also ensures that multi cord The rear part of twisting multi cord 502 twisting effect, if because multi cord relative to rotation twisting clamping position too slide It is possible compared to the number of twists applied to multi cord of the rotation quantity of revolving part to give a discount if slipping, influence " one turn two The efficiency of sth. made by twisting ".One weak point of the technical scheme principle that " oneself " therefore among Figure 10, " heptan " two subgraph are shown just exists In the traveling damping produced to multi cord it is slightly smaller compared to other technologies scheme some.Naturally in conjunction with directly applying to multi cord Radial clamping force and the technical scheme for allowing multi cord bending to produce radial clamping force both technical principles are not limited to Figure 10 As " pungent " subgraph is described, and Figure 10 " first ", " second ", " third ", " fourth ", " penta ", " oneself ", " heptan " and " pungent " subgraph institute The clamping mode for showing or even being described above based on above-mentioned subgraph can also carry out arbitrary independent assortment completely, come under this practicality The principle category of new technical scheme.

Figure 10 " nonyl " subgraph shows that the utility model makes revolving part apply indirectly to multi cord and directly radially pressed from both sides A kind of principle of technical scheme of clamp force, as shown in Figure 10 " nonyl " subgraph, is closely wound outside two revolving parts in left side One circle belt 2203, this two revolving part is again all through the 3rd rotation in the belt 2203 described with heavy black line in scheming and right side Turn part closely against, feed the multi cord of twister of the present utility model by held tight in the belt 2203 and figure it is right Between 3rd revolving part of side, in Fig. 10 under this situation of " nonyl " subgraph, except revolving part passes through the conveyer belt 2203 Directly multi cord is radially pressed and produced indirectly as tilted in figure outside the radial clamping force shown in solid black block arrow, also may be used To be generated using multi cord closely against the bending of revolving part and its axial tension produced under the traction of coiler device everywhere Radial clamping force as shown in black level filled arrows slightly smaller in figure, actually transmission belt in itself also can be to multi cords Apply radial clamping force, along with conveyer belt can cause some to be beneficial to the damping of rotation twisting to the traveling of multi cord, therefore A preferably balance can be realized between the beneficial traveling damping of increase radial clamping force and addition.Note due to multi cord Flexible " pungent ", " nonyl " two subgraph using Figure 10 technical scheme carry out rotation twisting preceding twisting multi cord 501 and it is rear plus Twist with the fingers multi cord 502 can also easily adjust same straight line keep straight on direction on and can as far as possible with all revolving parts rotation Turn axial line to overlap as far as possible, compared to traditional rotary spindle twister, can be completely eliminated and wear down in vain in air The generation of " air ring " phenomenon among resistance.Note what is described among Figure 10 shown in all subgraphs or even above based on above-mentioned subgraph The principle of technical scheme can also carry out arbitrary independent assortment completely, come under the principle model of the technical solution of the utility model Farmland.
