Vertical shaft a4 is fixed on the fine voile machine, tension pulley a2 and a1 up and down, and tension piece a3 goes here and there together on vertical shaft a4 by middle circular hole.Long filament a5 is from passing through between tension pulley a2 and the a1 up and down, and tension piece a3 pressurizes to yarn a5 by last tension pulley a2, and the size of pressure is by the quantity decision of tension piece a3.Because the structural reason of device own, in case yarn a5 enters up and down between the tension pulley a2 and a1, last tension pulley a2 can take place crooked together with tension piece a3.Such situation can produce following at least three defectives:
1, long filament can vacillated between the tension pulley up and down, because be tiltedly to put, there is motionless pressure different positions, and the tension force on the long filament will often change.
2, produce vibration inevitably during machine run, tension piece a3 has slight upper and lower displacement in the vibration, and this just means that the pressure on the long filament a5 can't stablize.
3, in addition, between tension pulley a2 and the a1, tangle when these flyings accumulation about the flyings that produce during the fine spining machine spinning can enter, the diameter that tangles along with these flyings slowly becomes greatly, and the pressure of long filament a5 just reduces gradually, is zero until long filament a5 upward pressure.Sometimes flyings twine and are clipped on the long filament, and when seriously hindering long filament and advancing, thread-tension can infinitely increase so that fracture occurs.
Perhaps, above-mentioned this ready-made tenslator is fit to for the thicker yarn of diameter, its tension fluctuation can not relate to the quality of yarn winder, but in long filament short fiber composite spinning is produced, the technological requirement thread-tension must be relatively stable reliable, and the mechanism of above-mentioned tension piece (perhaps spring) pressurization is obviously not competent.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of thread-tension control device special-purpose in long filament short fiber composite spinning is produced.
The present invention solves the problems of the technologies described above and has taked following technical measures, has promptly adopted a pedestal that straddles on the fine spining machine reel cage, and the pedestal top is provided with fixing hole, and pedestal and reel cage is fixed by fixing hole by fixed screw; Length direction along pedestal is provided with upper tension roller, active tension roller and location jockey pulley, described three jockey pulleys combine by the screw and nut and the pedestal of afterbody respectively, the active tension roller is located in the saturating groove of bent type on the pedestal, the position of adjusting active tension roller in the saturating groove of bent type can change the relative position between active tension roller and upper tension roller and the location jockey pulley, changes the cornerite of long filament to described three jockey pulleys thus; The locating slot that long filament location usefulness is arranged on the jockey pulley of described location.
Compare with traditional gravity type tenslator, the present invention has following advantage:
1, tension stability, after the cornerite between a denier filament and each jockey pulley was determined, tension force must be obeyed the Euler law (see figure 3), and the tension force in exit must be certain multiple of porch tension force.The vibration no matter machine run causes, or the influence of flyings in the workshop all can't influence the tension stability of long filament and the stability of the compound looping of staple fibre.
2, tension adjustment is convenient and reliable.The present invention is simple in structure, presses the position that the mentioned strain method of adjustment is adjusted the active tension roller, can regulate the tension force of long filament easily.
3, the long filament location is simple and reliable.The effect of the existing increase thread-tension of location jockey pulley, the positioning action that has long filament to import again, whole device is easy to use, and the location is reliable, the filament short-fiber composite yarn Stability Analysis of Structures of being produced, performance unanimity.

The specific embodiment
Fig. 4 is seen in the concrete enforcement of this device.
Long filament dedicated control device of the present invention is formed (see figure 2) by three little axle groups and pedestal.Upper tension roller 3, active tension roller 4 and location jockey pulley 5 combine with pedestal 1 by the screw 8 and the nut 9 of self afterbody respectively.Active tension roller 4 can be by saturating groove 7 adjusting positions of bent type on the pedestal 1.Be distributed with the long filament locating slot on the jockey pulley 5 of location.
Described pedestal 1 rides on the fine spining machine reel cage 14 and by hole 2 usefulness screws 15 and is fixed on the fine spining machine reel cage 14.During spinning, long filament 13 withdraws from from long filament bobbin 12, enters through upper tension roller 3, active tension roller 4 and location jockey pulley 5 in the jaw of fine spining machine front leather roller 10 and roller 11 compositions.Because long filament 13 is through three jockey pulleys, the long filament at jaw place has had certain force of strain before the feeding, and its size is decided by the cornerite between long filament 13 and three jockey pulleys.
