A disc type yarn tension device

A disc type yarn tension device comprises a shaft rod, and a fixed disc and a movable disc are inserted on the shaft rod in a sleeved mode. A first shaft sleeve and a second shaft sleeve are fixed to the fixed disc and the movable disc respectively. A first shaft of the fixed disc is fixed to the shaft rod through a set screw, a compression spring is pressed on the second shaft sleeve of the movable disc in an abutting-against mode, and the other end of the compression spring is pressed on an adjusting sleeve in an abutting-against mode. The adjusting sleeve is in threaded connection with the shaft rod, and a waist-shaped groove hole is formed in the front end face of the shaft rod and used for cutting the two side walls of the shaft rod. A T-shaped pull rod is inserted into the waist-shaped groove hole of the shaft rod in a sleeved mode, and the head of the pull rod is fixed on the second shaft sleeve of the movable disc and located between the compression spring and the second shaft sleeve. A handle is fixed to the pull rod through a bolt. The movable disc is pulled open through the pull rod, so that yarns conveniently and rapidly enter the space between the two discs, staff do not need to pull the yarns by the hands into the tension device, and then the occurrence of hand hurt and a yarn tensile failure is avoided.
