Description
Technical Field
The invention relates to a tension detection device, in particular to a silk thread tension detection device.
Background
In the textile process, the tension in the yarn during beaming (i.e., warping) has a significant effect on the quality of the yarn. Currently, there are two main tension detection methods for the yarns during warping: the first method is that a tension measuring instrument is used for randomly detecting one and two silk threads at irregular time, and whether the tension of the silk threads subjected to random detection has deviation is checked; the second is that the old skilled worker with special experience touches some silk threads running at high speed (about 2-5 m/s) by hands at variable time, judges the tension of the silk threads by feeling, and further determines whether the tension of the silk threads has deviation.
As the yarns are in gram units, the standard tension value of partial yarns is smaller, for example, the tension value of 10-30D yarns is generally between 4-8 g, and 1800 yarns can be simultaneously passed by the whole warp beam at most, so that the whole warp beam and even the whole cloth can become defective products by missing detection of one or two defective yarns. The first mode is machine selective examination, which inevitably has missed examination, and the second mode is manual selective examination, which not only has missed examination, but also has misjudgment.
