The present invention relates to a kind of spinning machine that is used for, the duo roth system of ring spinner or sir jet spinning machines particularly, it is right that this device has one pair of feeding roller, a coupled preliminary draft district, one pair of two apron roller that are located at this back, preliminary draft district is right, one pair to be located at this pair apron roller right to last apron, the apron band that it adjoins each other constitutes a two apron strip guiding device, this strip guiding device is from being formed between two apron rollers, it is right to be stretched over one pair of delivery roller in the jaw gap of the approaching side of two apron strip guiding devices, between two apron rollers pair and delivery roller, be provided with main drawing area, also have a condensers, this condensers is arranged on the front, jaw gap of the inherent two apron strip guiding devices in preliminary draft district and is bearing on the right roller of two apron rollers.
The strip of guiding by a duo roth system assembled from the side by a condensers before it enters the jaw gap of a pair of roller, and the fiber of strip is guided from the side, thereby having prevented that strip from floating scatters.This technology becomes known by EP 0 449 073A1, EP 0 417 614A1, DE 38 41 346A1.Knownly have the shortcoming that one or more condensers carry out the drafting system of work and be, drafting process is disturbed by the structural arrangements of condensers, thereby makes the advantageous effect obtained by condensers only because the existence of condensers itself and being cancelled at least in part.
The object of the present invention is to provide the duo roth system of another kind of the above-mentioned type.
Purpose of the present invention realizes by following technical scheme.Condensers has two condensers members, and these two members can around the common free swaying ground supporting of rotation of another right roller of two apron rollers, and is provided with a gap perpendicular to roller and the setting of strip throughput direction betwixt.
By structure of the present invention, just can make at the strip of preliminary draft district end and directly carry out polymerization from the side, and not disturb the preliminary draft process in the front in the jaw gap of two apron strip guiding devices.Particularly, make two apron rollers in the coarctate power in position, jaw gap, the condensers that in fact is not subjected to only to rest on down on the apron roller influences.Thereby make the condensers that is designed to two members that the fiber of strip can only be guided from the side.
For making drafting system, particularly its condensers can adapt to the various requirement of various spinning machine counter extensioin devices and the processing that adapts to various fiber species best best, the condensers member keeps together relatively movably mutually along the roller direction, and the width in gap therebetween can be regulated.
A simple especially structure of the present invention is, the condensers member keeps together mutually by an adjusting screw(rod), this adjusting screw(rod) has the thread segment of the opposite screw thread of two rotation directions, and each thread segment is respectively with the respective screw hole engagement on one of in two condensers members.
In order to make two mutual adjustings to a line of condensers member, a slide guiding device is set, and this device is best one of to be fixed in two condensers members pin in the corresponding through hole of going up and being slidably engaged on another condensers member, that stretch along the roller direction by one and to constitute.This has just guaranteed the accurately adjusting to a line mutually of two condensers members.
For the side direction polymerization that further improves strip and prevent strip side or downside are guided thereon, the condensers member in its opposed in opposite directions side, on the height in the jaw gap between the apron roller, have the breach of one and half bell mouth shapes, these breach enter the mouth towards bar subexit convergent from strip, and have a constant width in the gap between the condensers member on its outlet side total length perpendicular to the strip throughput direction at condensers.
Condensers is configured on the face of apron with apron is lip-deep at it at least and becomes complementary shape basically with its opposed part, and this just makes condensers can be arranged on especially front near the jaw gap of two apron strip guiding devices.
By being rested on the following apron and catch up with apron, two condensers members keep a small distance when working, make condensers can be close to the setting of jaw gap perfectly and don't condensers is pulled in the chock mode and enter in the feeding wedge mouth of two apron strip guiding devices front, do not hold thereby the apron roller can not squeezed.
Condensers is supporting movably along the roller axis direction, and helping making strip can follow this drafting system is general side direction reciprocating motion.
Condensers is bearing on the bearing part of upper leather ring roller by the overhanging shelf of width that at least one exceeds apron from the side.Shelf is L-shaped basically, it have one preferably be designed to fixed bar, be configured in the thigh portion on the condensers, another preferably be designed to connecting rod, be configured in the thigh portion on the bearing part.The thigh portion that is configured on the bearing part of each shelf can swingingly be provided with respect to condensers round an axis that is parallel to the setting of roller axis.The guide rod that each rotation of supporting the bearing part of a shelf to be designed to catch up with the apron roller is in line and aims at, shelf is provided on this guide rod movably along the direction of the rotation of upper leather ring roller.Shelf is configured in the bell-mouthed zone of a breach by half bell mouth shape feeding that constitute, condensers.These all are the particularly advantageous fixation of the condensers of drafting system of the present invention.
Since condensers can around upper leather ring roller swing and on shelf rotating structural arrangements-this shelf be preferably disposed in the bell-mouthed zone of feeding-just can realize that to act on the frictional force that acts between condensers and the following apron especially little and in fact the plus-pressure of apron do not exerted an influence.In practice, the thigh portion of the connecting rod form of shelf to be contained in un-rotatably on the condensers be desirable.
Embodiment shown in the present invention in conjunction with the drawings is described in detail, in the accompanying drawings,
Fig. 1 is the diagrammatic side view of a duo roth system;
Fig. 2 is the schematic diagram that the drafting system of Fig. 1 is seen along the arrow II of Fig. 1.
In two accompanying drawings, identical member indicates with identical label.
Shown in Fig. 1, a rove twisting or that do not twist or strip 10 infeed a pair of feeding roller 11,12.Sliver 10 is by a preliminary draft district 13.At the end in described preliminary draft district, a condensers 17 is set along the front that the strip throughput direction abuts against the jaw gap 14 of a pair of pair of apron roller 15,16.Strip 10 is imported into by the jaw gap 14 between the apron band that adjoins each other 18,19 of apron 20,21.Along with, strip 10 is by main drawing area 22 and a pair of delivery roller 23,24.Leave this to delivery roller 23,24 through the strip 10 of drawing-off ' be sent to a unshowned spinning organ, be spun into yarn there.
The upper leather ring 21 of guiding for example turns to by a unshowned cradle on upper leather ring roller 16, and on following apron roller 15 the following apron 20 of guiding for example by a guiding elements 25, also may turn to by another unshowned take up member.
Shown in Fig. 1 and 2, on every side of condensers 17, be provided with a connecting rod 26, this connecting rod 26 installs on the condensers 17 swingably or un-rotatably by a fixed bar 27.The end in addition of the guide hole which is provided with perforation 28 of connecting rod 26 swingably also can be along axis of orientation shown in the double-head arrow 46 to being slidingly arranged on the bearing part that is made of guide rod 29.Guide rod 29 this moment, the rotation A with upper leather ring roller 16 was fixed on the upper leather ring roller coaxially, thus condensers 17 can realize being parallel to rotation A's that is transverse to the reciprocating motion of strip throughput direction.
Condensers is the columniform abutment face 30 of part being provided with one towards two apron rollers on to a side of 15,16, and condensers is rotated on the following apron 20 of guiding on the apron roller 15 down in 14 fronts, jaw gap by this abutment face.One is columniform 32 of part and couples together with abutment face 30 by a seamed edge 31.This face 32 is caught up with apron roller 16 and is provided with one heart.Have a small distance d between that catch up with apron 21 at face 32 and its opposite external side, so condensers 17 can not contact with upper leather ring 21.
As shown in Figure 2, condensers 17 includes one first condensers plate 33 and one the second condensers plate 34 as the condensers member, has a gap 35 between two plates.On these two condensers plates 33,34, be provided with mutual adjusting to a line setting and have the tapped through hole 36,37 of reverse thread.In tapped through hole 36,37, pack into one and have the adjusting screw(rod) of a control member 39 and two sections thread segments 40,41.The width B in gap 35 can be adjusted on the required numerical value by operation adjusting screw(rod) 38 simply.
For making the abutment face 30 on two condensers plates 33,34 be in adjusting to a line, can on the first condensers plate 33, establish a guide hole 42, in guide hole, there is a pin 43 that is fixed on the second condensers plate 34 to be sliding engaged to it.
Two condensers plates 33,34 have a breach 44,45 respectively on its opposite side, form a guiding horn mouth altogether, and it is in the position of seamed edge 31, the width B that the narrowest position between abutment face 30 and face 32 equals gap 35.
In the spinning operating process, condensers 17 rests on down on the apron 20 with its abutment face 30, and condensers was arranged on seamed edge 31 positions at place, the narrowest position of its feeding horn mouth 44,45 and was close to two apron rollers on the right feeding wedge oral area position of two apron rollers of 15,16 14 fronts, jaw gap this moment.Because such structural arrangements of condensers 17, almost be to be right after arriving 14 fronts, jaw gap just closely to flock together through the fiber of the strip 10 of preliminary draft, make the strip that enters jaw gap 14 have required width.This has just prevented that independent edge yarn from laterally deflecting away from from strip, thereby has prevented that drafting process is disturbed.
Follow-on another advantage of swinging of the structural arrangements of condensers of the present invention is, condensers 17 can not be pulled and further enter two apron rollers in 15,16 the feeding wedge mouth, this is because at the abutment face 30 of condensers 17 and the force component that friction produced between the following apron 20, because the configuration of the dual articulated structure of condensers 17 is worked, this condensers is only rested on down on the apron 20 with the power that has reduced with respect to its weight.Therefore cause having reduced in the abutment face 30 of condensers 17 and the friction engagement between the following apron 20, simultaneously, the supporting force of axle 29 condensers that born 17, the particularly power perpendicular to the strip throughput direction can keep little of such degree, make that the plus-pressure between upper leather ring roller 16 and following apron roller 15 keeps in fact unaffected.
In practice, preferably adopt not rotatable structural arrangements.
