Problems solved by technology

However, the surface of the grooved roller is prone to fluff, and the mechanical grooved roller is easy to cause fiber damage, which affects the yarn quality
The technical starting point of dislocation spinning is to change the shape and size of the twisting triangle through the dislocation of the drafting unit and the twisting winding unit, thereby changing the movement of the fibers during the twisting process, and improving the yarn quality through the change of the yarn structure; However, at present, dislocation spinning is the dislocation of at least one spindle gauge, resulting in unstable yarn quality and many yarn breakages, which cannot be popularized in batches.

Embodiment Construction

[0009] In traditional ring spinning, the yarn rotates through the spindle, which drives the traveler (12) to rotate along the raceway of the steel ring (13), thereby transferring the twist to the joint between the front roller (4) and the front rubber roller (3). The twisted triangle (5) is formed at the whisker bar, and under normal spinning conditions, the shape of the twisted triangle (5) is usually an approximate symmetrical triangle. Depend on figure 1 and figure 2 As shown, a device for changing the shape of the twisting triangle in ring spinning is mainly composed of a bracket (1) and a pair of guide wheels (6) and (7) that can be positioned, and is installed on the front roller (4) and the car table. Between (2), adopt screw (14) to be fixed on the car platform (2). The main working mode of the device is as follows: After the fiber strands are output from the holding position of the front roller (4) and the front rubber roller (3), they first pass through the yarn g...

Abstract

The invention discloses a device for changing the form of a ring spinning twisting triangular space, which is arranged downstream final pairwise output rollers of a drafting part in a spinning frame. The device mainly comprises a bracket and a pair of yarn guide wheels which can be positioned. The device can be applied to the technical improvement of the spinning frame, changes the form of the twisting triangular space by the pair of positioned yarn guide wheels arranged on the vehicle top bracket so as to be favorable for reducing spinning hairiness and improving the evenness of yarns, and compared with the prior art, is simple and convenient to arrange and high in cost performance.

Description

technical field [0001] The invention relates to the field of spinning new technology, in particular to a device installed downstream of a drafting device of a ring spinning frame to change the shape of a twisting triangle by changing the original spinning path. Background technique [0002] Ring spinning technology is currently the most widely used spinning technology at home and abroad, but this technology increases the amount of hairiness due to the existence of twisting triangles. In recent years, many methods have been adopted to change the shape of the twisting triangle, such as compact spinning, cable spinning, dislocation spinning and other technologies, so as to reduce hairiness. [0003] The compact spinning technology mainly adds a fiber control area in front of the traditional drafting device, and uses the airflow to laterally condense the fiber bundles passing through the control area, so that the width of the fiber bundles is greatly reduced, which is almost clo...
