Problems solved by technology

[0003] In the spinning device used above, since the guide surface on the fiber guide member is made into a slightly twisted shape (that is, a slight spiral ), so the processing of the guide parts is difficult, and the vortex chamber of this spinning device has a large space, the airflow inside the vortex chamber rotates at a slow speed, and the eddy current twists the fibers slowly, which cannot fully enhance the breaking strength of the yarn. It is easy to produce weakly twisted yarn under the same pressure and number of tangential jet holes

Abstract

The invention relates to a yarn guiding device, and belongs to the technical field of textile machinery. The yarn guiding device comprises a guiding block (1), a shell (2) and a vortex tube (6), wherein the guiding block (1) is arranged in the shell (2), the guiding block (1) comprises a cylindrical guiding block base body (10) and a conical boss (7), a positioning block (11) is arranged at the rear end of the cylindrical guiding block base body (10), the front side of the portion, from the front end to the middle, of the cylindrical guiding block base body (10) is cut off to form a second guiding face (12), the front side of the portion, from the middle to the positioning block (11) at the rear end, of the cylindrical guiding block base body (10) is cut off to form a first guiding face (3), and the front side of the portion from the front end of the cylindrical guiding block base body (10) to the front end of the conical boss (7) is cut off to form a third guiding face (13). According to the yarn guiding device, the rotational speed of air flow inside a swirl chamber can be increased, the twisting speed of yarn is high, the yield of the final yarn is increased, and the breaking strength of the final yarn is improved.

Description

technical field [0001] The invention relates to a yarn guiding device, which belongs to the technical field of textile machinery. Background technique [0002] Currently, methods and devices are known for producing these spun yarns using swirling air streams. Chinese patent CN1038438C discloses a spinning device, which includes a fiber guiding part, which includes a slightly twisted guiding surface, and forms a fiber feeding channel with the inlet wall of the spinning device. The fiber guiding member is made roughly in the shape of a truncated cone with a large diameter at the top end and a small diameter at the bottom end, and is twisted slightly along the slit in the swirling direction of the swirling airflow, and then moves along the longitudinal direction from the large diameter at the top end. A shape cut off on one side. A concentric guide needle for twist resistance is also installed in the exit area of ​​the fiber feed channel. An annular vortex chamber is install...
