Description

Yarn tension adjusting device of polyester yarn spinning machine Technical Field The utility model relates to the technical field of tension adjusting devices, in particular to a yarn tension adjusting device of a polyester yarn spinning machine. Background Textile machines, also called textile machines, looms, cotton machines, etc., are ancient textile machines that rely on man power to drive. The spinning machine is a full scale of a tool for processing raw materials such as threads, silk, hemp and the like into silk threads and then weaving the silk threads into cloth, and when the spinning machine is used, the tension of yarns needs to be regulated to prevent the yarns from loosening. Through searching, the prior patent (publication number: CN 216972765U) discloses a tension adjusting device of a roving frame for spinning, which comprises a base plate, an adjusting mechanism and a waxing mechanism, wherein the top of the base plate is vertically and fixedly connected with a fixing frame, and the adjusting mechanism is arranged at the top of the base plate and is positioned below the fixing frame. This roving frame's for spinning tension adjusting device, the yarn is through the surface phase contact with auxiliary wheel and the surface of regulating wheel, the extension or the shrink of first electric telescopic handle change the position of regulating wheel, thereby change the tension size of yarn, the synchronous extension of second electric telescopic handle is according to the position of regulating wheel or shrink when changing, make wax rolling axle carry out laminating waxing to the yarn, guarantee its waxing effect, adjust tension to the yarn, can carry out waxing to the yarn when adjusting tension, protect the yarn, avoid follow-up wearing and tearing, the production effect is better.
