Yarn tension control device for loom

Abstract

The invention discloses a yarn tension control device for a loom, which comprises a base and a tension adjustment frame fixed on the base. A movable plate is arranged above the tension adjustment frame. The inside of the tension adjustment frame is vertically A lifting shaft is installed for moving in the direction, and a yarn regulating wheel is installed in the rotation of the middle part of the lifting shaft. The left side and the right side of the yarn regulating wheel are respectively provided with a first yarn guiding wheel and a second yarn guiding wheel, and the first yarn guiding wheel and the second yarn guide wheel are installed and fixed on the two side frame openings of the tension adjusting frame respectively through the wheel shaft. Through the two-stage control of the cam drive structure and the screw drive structure, the present invention can carry out self-adaptive control of the tension of the yarn, avoiding the trouble of manual control in the past, which is beneficial to ensure the delivery of the yarn, and can prevent the tension of the yarn The thread is too tight during the conveying process and causes the problem of broken thread, which greatly meets the needs of people.

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...
