Abstract
The utility model discloses a yarn constant tension device for adjusting the tension of yarn at the bobbin backing-off position on a yarn frame. The number of bobbins is multiple, and tension device bodies corresponding to the bobbins in a one-to-one mode are arranged. Each tension device body comprises at least one yarn guiding pipe, and further comprises a motor and a rectilinear movement mechanism which is driven by the motor via a worm and gear transmission mechanism. Each rectilinear movement mechanism comprises a lead screw and a lead screw nut, wherein the lead screw is driven by a worm wheel to rotate, the lead screw nut is driven by the lead screw to do rectilinear movement, and the lead screw nut is screwed on the body of the lead screw. The yarn guiding pipes are fixedly installed on the lead screw nuts respectively. Each tension device body is provided with three yarn guiding pipes, and the lead screws and the lead screw nuts are installed on the yarn frame and incline towards the center direction of the bobbins. The yarn guiding pipes are vertically and fixedly installed on the corresponding lead screw nuts in the longitudinal direction of the yarn frame. The yarn tension at the bobbin backing-off position can be kept stable, and yarn collapsing and yarn breaking accidents can be avoided.
Description
Technical field
The utility model relates to a kind of yarn tension-adjusting gear, particularly relates to the yarn constant tension device that is used for regulating yarn tension in warping machine or tricot machine.
Background technology
In existing warping machine or tricot machine, be used for regulating the tension-adjusting gear of yarn cylinder unwinding place yarn tension on creel, comprise three thread tubes that corresponding each yarn cylinder arranges, described three thread tube space certain distances, be fixedly mounted in parallel to each other on the cramp bar of creel, described cramp bar is fixedly connected with creel; In when work, yarn unwinding from yarn cylinder, the knitting mechanism that the warping mechanism of sending into warping machine after described thread tube adjustment of tonicity carries out warping or sends into tricot machine weaves.Although the structure of this tension-adjusting gear is simple, but also there is at work following shortcoming, along with the yarn on yarn cylinder constantly reduces, the diameter of yarn cylinder constantly diminishes, on yarn cylinder, yarn to the distance between thread tube constantly increases thereupon, thereby cause the pulling force that yarn is subject to change, cause yarn tension unstable, even cause the yarn that collapses, broken yarn accident.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of in the process of yarn unwinding from yarn cylinder, can make the tension force of yarn keep stable, thus the yarn constant tension device of avoid collapsing yarn and broken yarn accident.
For solving the problems of the technologies described above, the utility model adopts a kind of like this yarn constant tension device, this device is for regulating the tension force of the yarn cylinder unwinding place yarn on creel, described yarn cylinder has a plurality of, corresponding each yarn cylinder all arranges a tensioner, each tensioner includes at least one thread tube, described each tensioner all also comprises motor and the straight-line motion mechanism being driven by Worm and worm-wheel gearing by this motor, described straight-line motion mechanism comprises the screw mandrel being rotated by worm gear drive and the feed screw nut who is driven moving linearly by described screw mandrel, described feed screw nut is screwed on the shaft of described screw mandrel, described thread tube is fixedly mounted on described feed screw nut.
In the utility model, each tensioner is equipped with three thread tubes, described three thread tube space certain distances, is fixedly mounted on described feed screw nut in parallel to each other.
Adopt after said structure, because thread tube is fixedly mounted on feed screw nut, thereby when work, by motor, by Worm and worm-wheel gearing, drive screw mandrel to rotate, screw mandrel drives feed screw nut and thread tube moving linearly, like this along with yarn cylinder diameter constantly dwindles, thread tube also constantly dwindles with respect to the distance at Sha Tong center thereupon, thereby yarn to the distance between thread tube on yarn cylinder is remained unchanged, therefore guaranteed the tension stability of yarn, avoid collapsing yarn and broken yarn accident.And, of the present utility model simple in structure, be convenient to implement.
In the utility model, described screw mandrel and feed screw nut are arranged on creel and are in tilted layout towards the center position of yarn cylinder, and described thread tube is longitudinally vertically fixedly mounted on described feed screw nut along creel.Adopt after said structure, can guarantee better that the tension force of yarn keeps stable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a kind of structural representation of the utility model yarn constant tension device.
Fig. 2 is a kind of local structure schematic diagram of the utility model yarn constant tension device.
The specific embodiment
Referring to Fig. 1, the 2 a kind of yarn constant tension devices that show, this device is for regulating the tension force of the yarn cylinder 5 unwinding place yarn 5-1 on creel 6, described yarn cylinder 5 has a plurality of, corresponding each yarn cylinder 5 all arranges a tensioner, each tensioner includes at least one thread tube 4, described each tensioner all also comprises motor 1 and the straight-line motion mechanism being driven by Worm and worm-wheel gearing 7 by this motor 1, described straight-line motion mechanism comprises the screw mandrel 2 being rotated by worm gear 7-1 drive and the feed screw nut 3 who is driven moving linearlies by described screw mandrel 2, described feed screw nut 3 is screwed on the shaft of described screw mandrel 2, described thread tube 4 is fixedly mounted on described feed screw nut 3.Worm screw 7-2 in the utility model Worm and worm-wheel gearing 7 is driven and is rotated by motor 1, and screw mandrel 2 is fixedly connected with described worm gear 7-1.
In the utility model, as shown in Figure 1, 2, described screw mandrel 2 and feed screw nut 3 are arranged on creel 6 and are in tilted layout towards the center position of yarn cylinder 5, and described thread tube 4 is longitudinally vertically fixedly mounted on described feed screw nut 3 along creel 6.
In the utility model, each tensioner is preferably equipped with three thread tubes 4, described three thread tubes, 4 space certain distances, is fixedly mounted on described feed screw nut 3, as shown in Figure 1, 2 in parallel to each other.
Working process of the present utility model is as follows: as shown in Figure 1, yarn 5-1 unwinding from yarn cylinder 5, meanwhile, motor 1 drives screw mandrel 2 to rotate by Worm and worm-wheel gearing 7, feed screw nut 3 on screw mandrel 2 its shafts of drive and thread tube 4 are towards the center position moving linearly of yarn cylinder 5, like this along with yarn cylinder 5 diameters constantly dwindle, thread tube 4 also constantly dwindles with respect to the distance at yarn cylinder 5 centers thereupon, thereby make on yarn cylinder 5 yarn 5-1 remain unchanged to the distance between thread tube 4, therefore guaranteed the tension stability of yarn 5-1, avoid collapsing yarn and broken yarn accident.
