Yarn tension adjusting and controlling device of loom

Abstract

The invention discloses a yarn tension adjusting and controlling device of a loom. The yarn tension adjusting and controlling device comprises a base and a tension adjusting frame fixed to the base, amovable plate is arranged above the tension adjusting frame, a lifting shaft is movably installed in the tension adjusting frame in the vertical direction, and a yarn adjusting wheel is rotatably installed in the middle of the lifting shaft; and a first yarn guide wheel and a second yarn guide wheel are arranged at the left side and the right side of the yarn adjusting wheel correspondingly, andthe first yarn guide wheel and the second yarn guide wheel are installed and fixed to frame openings in the two sides of the tension adjusting frame through wheel shafts correspondingly. According tothe yarn tension adjusting and controlling device, through two-stage adjusting and controlling of a cam transmission structure and a lead screw transmission structure, the tension of yarns can be adjusted and controlled in a self-adaptive manner, the trouble that manual adjustment and control are needed in the prior art is avoided, it is guaranteed that the yarns are conveyed easily, the problem that the yarns are too tight in the conveying process, and consequently yarn breaking is caused can be solved, and the use requirements of people are greatly met.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn tension control device for a loom. Background technique [0002] In the weaving process of the textile industry, it is necessary to control the tension of the yarn. The yarn is drawn from the yarn wheel and arranged into warp threads. The textile process requires uniform tension of the warp threads, otherwise the cloth surface will be uneven and easy to wrap. In the weaving process, different yarns will be transported, and the yarn transport is more demanding than the fabric transport, and the tension of the yarn is not easy to be too loose or too tight, otherwise when the tension of the yarn is too loose, It cannot be effectively conveyed; and when the tension of the yarn is too tight, the friction between the yarn and the yarn guide wheel increases during the conveying process, which easily causes the problem of thread breakage; The yarn tension of the cloth machine i...
