Abstract

The invention discloses a yarn pretension regulating device, and belongs to the technical field of spinning. The yarn pretension regulating device comprises a contact wheel, periphery of which is wound with a yarn, and further comprises a movable frame, a telescopic pole, a base frame and a regulating mechanism, wherein the contact wheel can be rotatably mounted at one end of the movable frame; the telescopic pole is fixedly arranged at the other end of the movable frame; the telescopic pole is arranged on the base frame in a penetrating mode, and is controlled by the regulating mechanism for being axially regulated; the regulating mechanism comprises a regulating gear, a regulating handle, a supporting wheel and a regulating bolt; a guide rack, which is engaged with the regulating gear, and has a length direction consistent with the axial direction of the telescopic pole, is arranged on the telescopic pole; the regulating gear and the supporting wheel are separately arranged at two opposite sides of the telescopic pole; a threaded part of the regulating bolt is arranged on the base frame in the penetrating mode; and the end part of the regulating bolt abuts against the end part of the telescopic pole. The yarn pretension regulating device is convenient for precisely regulating tension degree of the yarn.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn pretension adjusting device. Background technique [0002] During the weaving process, the tension of the yarn needs to be pre-tightened so as not to loosen and cause the yarn to slip. The yarn pretension adjustment device includes a contact wheel whose outer circumference is entangled with the yarn, and also includes a movable frame, a telescopic rod, a basic frame, and an adjustment mechanism. The contact wheel is rotatably installed at one end of the movable frame, and the telescopic rod is fixed on the movable frame. At the other end, the telescopic rod is mounted on the base frame and controlled by the adjustment mechanism for axial adjustment. [0003] However, the adjustment mechanism of the yarn pretension adjustment device often cannot achieve accurate and stable adjustment, which makes it difficult to achieve an appropriate level of yarn tension.
