Silk thread tensity sensing device of automatic raw silk denier

The utility model discloses a silk yarn tensity sensing device of an automatic raw silk denier. The silk yarn tensity sensing device comprises a fixing frame, a tension meter, a silk guide ring and a support. The tension meter is fixedly installed on the fixing frame, and godet wheels at the front end of the tension meter are vertically arranged. The two wire guide rings are arranged above and below a wire guide wheel of the tension meter through a bracket; the support is fixedly installed on the fixing frame. The sensing device designed by the utility model is mainly arranged on the raw silk automatic denier machine and is used for sensing the tension degree condition of silk threads in the raw silk denier weighing process, so that weighing errors caused by the fact that the silk threads tension and weigh the mass of a bobbin (silk spindle) are avoided; when the silk thread is in a tensioning state, weighing is stopped through program control program setting, and weighing is started after the silk thread is
