A splicing device and method for increasing the strength of a spun yarn

Abstract

The application relates to the technical field of spinning thread twisting, and discloses a twisting device and method for improving the strength of spinning thread, which comprises the following components: symmetrically-arranged spinning thread end fixing parts, which are used for fixing the spinning thread ends and ensuring the uniform length of the spinning thread ends; a sliding fixing part, wherein the symmetrically-arranged spinning thread end fixing parts are symmetrically connected to the sliding fixing part in a sliding mode and move towards each other; an open-weaving twisting part, which is fixed on the sliding fixing part and comprises a twisting part and an open-weaving part which is connected to the twisting part in a sliding mode; and the spinning thread end fixing parts, the sliding fixing part and the open-weaving twisting part are respectively provided with a placing cavity, an open-weaving cavity and a twisting cavity with the same center; the spinning thread enters the open-weaving cavity first to realize open-weaving of the joint, and then enters the twisting cavity to complete twisting of the joint; and the device solves the problem that the strength of the joint position of traditional siro spinning twisting is prone to sudden reduction.
