This invention relates to an adjustable tension three-dimensional knitting
yarn carrier, comprising a mounting frame, a
yarn guide, and a rotating shaft. The mounting frame has a rotational damping mechanism and a damping adjustment mechanism on its left and right sides, respectively. The rotational damping mechanism includes a
yarn bobbin, a
coil spring, and a
coil spring sleeve. A
coil spring, a coil spring sleeve, and a yarn
bobbin are sequentially fitted onto the outer side of one end of the rotating shaft. The two legs of the coil spring are fixed to the rotating shaft and the coil spring sleeve, respectively. The coil spring sleeve and the yarn
bobbin are fixedly connected. The damping adjustment mechanism includes a pressure rod, a pressure plate, a counter-rotating wave spring, a pressure plate, and a connecting screw. The other end of the rotating shaft is inserted into the pressure rod, which can rotate with the rotating shaft. The pressure rod is fixed to one side of the pressure plate. The counter-rotating wave spring is installed between the mounting frame and the pressure plate. The pressure plate is fixed to the mounting frame by the connecting screw, and the pressure plate presses tightly against the pressure plate. The counter-rotating wave spring is sleeved on the pressure rod. This invention can achieve uniform and adjustable
yarn tension while greatly increasing the yarn feed rate, thereby improving the knitting quality of three-dimensional knitted fabrics.
