Abstract
The utility model discloses a yarn tension adjusting 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 adjusting device bodies corresponding to the bobbins in a one-to-one mode are arranged. Each tension adjusting device body comprises at least one yarn guiding pipe. Each tension adjusting device body further comprises a motor and a rectilinear movement mechanism driven by the motor. Each rectilinear movement mechanism comprises a gear and a rack, wherein the gear is driven by the motor to rotate, the rack is driven by the gear to do rectilinear movement, and the rack is meshed with the gear in a matched mode. The yarn guiding pipes are fixedly installed on the corresponding racks. The racks are preferably in sliding fit with a rectilinear guide rail fixed on the yarn frame, the racks incline towards the center direction of the bobbins, and the yarn guiding pipes are vertically and fixedly installed on the corresponding racks in the longitudinal direction of the yarn frame. The tension of the yarn 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 device that is used for regulating yarn tension in warping machines or warp knitting machine.
Background technology
In existing warping machines or warp knitting machine, be used for regulating the device of yarn cylinder unwinding place yarn tension on creel, comprise three yarn-guide tubes that corresponding each yarn cylinder arranges, described three yarn-guide 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 machines after described yarn-guide tube adjustment of tonicity carries out warping or sends into warp knitting machine weaves.Although the structure of this yarn 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 yarn-guide 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 tension-adjusting gear 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 tension-adjusting gear, 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 tension-adjusting gear, each tension-adjusting gear includes at least one yarn-guide tube, described each tension-adjusting gear all also comprises motor and by this motor-driven straight-line motion mechanism, described straight-line motion mechanism comprises the gear that drive to be rotated by motor and by the tooth bar of described gear driven moving linearly, described tooth bar and described gear engagement fit, described yarn-guide tube is fixedly mounted on described tooth bar.
In the utility model, each tension-adjusting gear is equipped with three yarn-guide tubes, described three yarn-guide tube space certain distances, is fixedly mounted on described tooth bar in parallel to each other.
Adopt after said structure, because yarn-guide tube is fixedly mounted on tooth bar, thereby when work, by motor-driven gear, rotated, gear driven tooth bar and yarn-guide tube moving linearly, like this along with yarn cylinder diameter constantly dwindles, yarn-guide tube also constantly dwindles with respect to the distance at Sha Tong center thereupon, thereby yarn to the distance between corresponding yarn-guide tube on each 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 tooth bar and the line slideway being fixed on creel are slidably matched, and described tooth bar is in tilted layout towards the center position of yarn cylinder, and described yarn-guide tube is longitudinally vertically fixedly mounted on described tooth bar 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 tension-adjusting gear.
Fig. 2 is a kind of partial structurtes enlarged diagram of the utility model yarn tension-adjusting gear.
The specific embodiment
Referring to Fig. 1, a kind of yarn tension-adjusting gear shown in 2, 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 tension-adjusting gear, each tension-adjusting gear includes at least one yarn-guide tube 4, described each tension-adjusting gear all also comprises motor 1 and the straight-line motion mechanism being driven by this motor 1, described straight-line motion mechanism comprises the gear 2 being rotated by motor 1 driving and the tooth bar 3 that is driven moving linearlies by described gear 2, described tooth bar 3 and described gear 2 engagement fit, described yarn-guide tube 4 is fixedly mounted on described tooth bar 3.
In the utility model, as shown in Figure 2, described tooth bar 3 is preferably slidably matched with the line slideway 7 being fixed on creel 6, and described tooth bar 3 is in tilted layout towards the center position of yarn cylinder 5, and described yarn-guide tube 4 is longitudinally vertically fixedly mounted on described tooth bar 3 along creel 6.
In the utility model, each tension-adjusting gear is preferably equipped with three yarn-guide tubes 4, described three yarn-guide tubes, 4 space certain distances, is fixedly mounted on described tooth bar 3 in parallel to each other.
The course of work of the present utility model is as follows: referring to Fig. 2, yarn 5-1 unwinding from yarn cylinder 5, meanwhile, motor 1 driven wheel 2 rotates, gear 2 is the center position moving linearly towards yarn cylinder 5 with carry-over bar 3 and yarn-guide tube 4, like this along with yarn cylinder 5 diameters constantly dwindle, yarn-guide 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 yarn-guide tube 4, therefore the tension stability of yarn 5-1, avoid collapsing yarn and broken yarn accident have been guaranteed.
