Description
The present invention is a kind of novel five reciprocal moulding groove drums, the reciprocal winding molding mechanism that it is applicable to that production of chemical fibre adopts.
As everyone knows, back and forth the moulding groove drum is one of major part in the various winding mechanisms, and it is a cylinder bodily form grooved cam normally.All adopt the single head groove drum in the spinning winding mechanism at present, the traverse that filar guide is done straight reciprocating motion by its groove is a definite value, exists the residence time at the two ends of traverse, again because there is a segment distance in ceiling structure system between seal wire point and the winding point.Two ends lamination protuberance appears in the silk tube of therefore being reeled inevitably, and rolling density is big, the hardness height, and promptly so-called chimb, or claim phenomenon in one's ear, thus cause irregularity to rise, influence fiber quality.
In order to eliminate this phenomenon in one's ear, extremely the method that is adopted so far has four kinds.The one, the bull method promptly increases groove drum thread guide traverse number, has made it the long weak point that has, to reduce silk tube end laying height; The 2nd, carry roller method, even strand is set up roller device by one before coiling, roller speed to reach minimizing tension force, improves purpose in one's ear a little more than silk tube coiling speed; The 3rd, double flute tube method promptly increases a grooved roller, makes the winding tension of silk even, improves in one's ear; The 4th, shorten the distance between winding point and the seal wire point, reduce the delay time of commutating, improve purpose in one's ear to reach.
Obviously, the two the 3 two kinds of methods certainly will increase facility load, special at chemical fiber high speed spinning such as coiling speed under the condition more than 3000 meters/minute, not only make technology and complicated operationization, and the actuating device frequency conversion of groove drum proposed higher requirement, common converter plant then can't adapt to.The 4th kind of method shortened the distance that reaches capacity at present.Therefore, first kind of bull method of development become the important channel with the phenomenon in one's ear of improving the silk tube.
Till the present invention, the bull groove drum that is adopted has double end (or four lines), three (or six lines) and four-head (or the eight lines) groove drum that back and forth is shaped.In an oscillation cycle, the commutation number of times is respectively secondary, three times and four times, and the reciprocating traverse number average of filar guide has only two.Described three groove drums of the special clear 53-61735 of Japanese Patent JP, in an oscillation cycle, filar guide side-to-side movement commutation number of times is three times, has two kinds of traverse numbers and six and turns to arc.But only once change the turning point axial location, therefore on the degree of improving in one's ear, be restricted, the desirable requirement of out of reach.
Purpose of the present invention is intended to solve above-mentioned three and four-head groove drum deficiency, and further raising silk tube two ends distributing homogeneity and elimination are in one's ear.
The invention process main points.It is cylindrical five cephalic groove grooved cams, the filar guide that embeds groove back and forth traverses with the groove drum revolution, curve transition is sentenced in two ends commutations, it is characterized in that the closed curves that groove is made up of five left-hands and five right hand belixs and each five commutations of the right and left arc.Filar guide has three traverses different in size and changes the turning point axial location twice when helix line is done reciprocal uniform rectilinear motion.
One of main points of the present invention are the selections of groove drum line number and filar guide traverse.Now the experiment parameter with three kinds of different groove drums reduces table 1.
* the groove drum diameter is 100mm.The η value is a groove drum revolution in the filar guide one stroke.
Three kinds of groove drums are 3500 meters/minute at spinning speed in the table 1, and when winding angle was 7 °, the silk tube was shaped best with the 6 7th kind five ten wire casing tubes, and three six wire casing tubes take second place.A silk tube diameter is 300mm, and the silk tube is wide when be 248mm, and silk tube two ends vertex and intermediate altitude difference are about 1.0mm, and end face is concordant, is shaped well.
The undrawn yarn tube end face silk layer lay distribution with three kinds of bull groove drums in the table 1 now gives comparison.
If α is a silk tube end face density and the ratio of intermediate density, γ be a silk layer intermediate density.According to calculating as can be known, the density contrast of coiling end seldom is middle two times, so take α=2, γ=1.Monolateral silk layer lay zone may be partitioned into △
1, △
2, △
3, △
4, then each calculation of parameter result is concluded as table 2.
Three kinds of silk tubes of table 2 end silk layer lay parameter
Therefore the density contrast of five groove drums is minimum also to have four deposit region, so a silk tube end face lay is evenly distributed, other three, four-head are worsened successively.
In sum, three of filar guide traverses are relevant with silk tube width with the winding mechanism form.When adopting the friction-type up-coiler, when silk tube width was 100～250 millimeters, its length was respectively H
1=94～244 millimeters, H
2=96.5～246.5 millimeters, H
3=102～252 millimeters; When adopting the spindle driving type up-coiler, when silk tube width was 160～220 millimeters, its length was respectively H
1=152～212 millimeters, H
2=160～220 millimeters, H
3=168～228 millimeters.
Two of main points of the present invention are that the reciprocating progressive error of filar guide is the selection of amount of contraction △ C.Amount of contraction H as shown in the drawing

2=3～4 millimeters, be preferably 3.5 millimeters; When adopting the spindle driving type winding mechanism, △ C
1=14～18 millimeters, be preferably 16 millimeters, △ C
2=7～9 millimeters, be preferably 8 millimeters.Indenture can appear as the excessive then silk of △ C value tube end, on the contrary too small then inoperative in one's ear as △ C value to improving.
The characteristic data such as the table 3 of five groove drums of the present invention and peculiar three kinds of different strokes thereof are listed.
Five groove drum parameters of two kinds of winding mechanisms of table 3
* f-groove drum revolution/filar guide umber of reciprocation; M-groove curve point of crossing;
L-silk tube shaping width; β-groove drum groove curve angle of obliquity aviation value;
The axial coordinate value at S-steering curve and helix line point of contact; D-groove drum diameter.
Three of main points of the present invention are the axial coordinate value S at steering curve and helix line point of contact.Because the groove drum rotation promotes the filar guide linear reciprocating motion, motion absolute velocitye was zero by dropping at a high speed in the short time at the utmost point when filar guide turned to, and rise to rapidly at a high speed by zero again, so filar guide not only impacts the groove drum groove, and itself also bears identical counterforce.Experiment shows, filar guide turns to the arc impulsive force that moves more even along parabola, and it is good steering curve that parabola turns to arc, suitably strengthens the impulsive force that turns to that S value that parabola turns to arc can reduce filar guide.When silk tube width was 220～260 millimeters, S was 8～12 millimeters, was preferably 10 millimeters; When silk tube width was 180～220 millimeters, S was 6～10 millimeters, was preferably 8 millimeters; When silk tube width was 100～140 millimeters, S was 3～6 millimeters, was preferably 4.5 millimeters.
Because five groove drums of the present invention have three kinds of thread guide traverses different in size, end, silk tube two ends high density area can be moved to the centre with twice different designs numerical value, reach silk tube end and intermediate density effect of uniform.Bull groove drum before the present invention can be eliminated phenomenon in one's ear to greatest extent.It improves 10% than the shop silk homogeneity of three groove drums, and has best anti-stacked performance; Can save anti-patterning device than present external widely used single head groove drum.Again because five groove drums rotating speed under identical seal wire number of times is low, so require low to the rotating converter plant of control groove drum.Each groove and filar guide abrasion number of times are few, and it is low therefore to heat up, long service life.
Simultaneously, the comformability of five groove drums of the present invention is extensive, can be used for various low speed, middling speed and the high-revolving various fiber winding mechanism from 1 meter/minute～4000 meters/minute, and it both had been applicable to the friction-type winding mechanism, also was applicable to spindle driving type fiber winding mechanism.
