Abstract
The invention discloses a tension control method. Specific number values of warp tension are accurately acquired according to a heald frame, beating-up, dropper shake and weaving machine vibration in the running process of a weaving machine, calculated by means of a data processing algorithm to obtain a real warp tension value, a detection value in the running process of the weaving machine is not influenced by measurement errors caused by rear beam movement and heald frame opening and closing through a tension control device, constant tension is achieved, and even and consistent upper weft threads of a fabric are kept.
Description
Technical field
The present invention relates to textile technology and equipment technical field, particularly relate to method and the device thereof of the control of a kind of weaving-machine tension.
Background technology
The loom of electronic warp feeding is adopted to need to detect warp tension in process of textile production, constant tension will be kept in weaving process to be desirable situation, because weaving process, fabric etc. are changeful in actual production process, the diameter of the warp beam of supply warp thread reduces gradually with the supply of warp thread, warp thread distortion also cannot be estimated, so control to be technological difficulties to tension force, be generally adopt rough control, allow larger fluctuation range.And control roughly tension force and cause in loom weaving process, the last cycle and cycle tension error below large, show that the gap on cloth cover between each weft yarn is uneven, the lighter reduces cloth grade, and severe one fabric becomes waste product.
Summary of the invention
Object of the present invention: for solving the problems of the technologies described above, accurately controls the warp tension in loom weaving process, realizes constant tension, ensures that upper weft thread gap uniformity is consistent.
A kind of tension control method of the present invention, according to heald frame in loom running, beat up, menopause tablet shake, looms vibration motion artifacts in the concrete numerical value of precise acquisition warp tension, the numerical value of collection is calculated real warp tension value through data processing algorithm, rotating speed and the position of let-off motor is controlled according to true warp tension change, and accurately control warp tension by tenslator, make it keep constant.
Its structure of a kind of tenslator of the present invention is 3 beam composition three-legged structures of heald frame end, wherein, the beam mediated is for detecting beam, the beam being in two side positions is brace summer, the axial connecting line of 3 beams forms a triangle, with the axle center detecting beam for the angle of summit and supported on both sides beam is 60 ° ~ 150 °.
Preferably, the axle center of described detection beam is the angle of summit and supported on both sides beam is 120 °.
Preferably, described brace summer overlaps is 1 brace summer.
The invention has the advantages that, by tension control method and device thereof make in loom running detected value not by the back rest move with heald frame folding cause the impact of measure error, realize constant tension, maintain the even, consistent of fabrics cloth cover weft yarn gap.

Be labeled as shown in above accompanying drawing: 1 heald frame, 2 detects beam, 3 brace summers.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment and accompanying drawing, the present invention is described in further details.At this, exemplary embodiment of the present invention and illustrating for explaining the present invention, but not as a limitation of the invention.
A kind of tension control method of the present invention, according to heald frame in loom running, beat up, menopause tablet shake, looms vibration motion artifacts in the concrete numerical value of precise acquisition warp tension, the numerical value of collection is calculated real warp tension value through data processing algorithm, rotating speed and the position of let-off motor is controlled according to true warp tension change, and accurately control warp tension by tenslator, make it keep constant.
Its structure of a kind of tenslator of the present invention is 3 beam composition three-legged structures of heald frame end, wherein, the beam mediated is for detecting beam, the beam being in two side positions is brace summer, the axial connecting line of 3 beams forms a triangle, with the axle center detecting beam for the angle of summit and supported on both sides beam is 60 ° ~ 150 °.
As shown in Figure 1, the beam mediated is for detecting beam, and the beam being in two side positions is brace summer, and the axial connecting line of 3 beams forms a triangle, with the axle center detecting beam for the angle of summit and supported on both sides beam is 120 °
As shown in Figure 2, the beam mediated is for detecting beam, and the beam being in two side positions is brace summer, and it is 1 that the brace summer of both sides overlaps.
Above-described detailed description of the invention; further detailed description has been carried out to object of the present invention, technical scheme and beneficial effect; be understood that; the above is the specific embodiment of the present invention, the protection domain be not intended to limit the present invention, within the spirit and principles in the present invention all; any amendment of making; equivalent replacement, improves, is all included in protection scope of the present invention.
