Description

Technical Field

[0001] The invention relates to the technical field related to filament manufacturing, and in particular to an anti-entanglement spinning device and method for weaving aramid silk fibers. Background Art

[0002] Spinning is also called chemical fiber forming. It is a process of manufacturing chemical fibers. It is a process of making certain polymer compounds into colloidal solutions or melting them into melts and then extruding them through the fine holes of the spinneret to form chemical fibers.

[0003] The existing Chinese patent document with the announcement number CN210684019U discloses a head roller for a melt spinning machine to prevent roller shaft winding. The scheme mainly consists of a threading plate, an upper roller, a lower roller, an anti-winding device, a roller fixing plate, a combing device and other parts, and has a simple structure. The anti-winding device is installed 5CM above the root of the upper roller. The anti-winding device is a circular slide plate with a downward inclination of 45° and is 4cm longer than the upper roller. When the machine is turned on, high-strength polypropylene yarn falls from the top, is combed and pulled by the combing device, and the yarn is wound on the head roller.

[0004] However, the upper roller and the lower roller in the above scheme both use a circular slide plate with a downward inclination of 45° to prevent the silk thread from being entangled. However, the above scheme cannot effectively prevent the silk thread from being offset on the upper roller and the lower roller, and the external circular slide plate will occupy more space and may cause interference friction to the movement of the silk thread, thereby causing the silk thread to be damaged by friction, thereby affecting the overall strength of the silk thread, and the friction process will generate more static electricity, thereby causing adhesion between the silk threads, thereby further increasing the risk of silk thread entanglement. For this reason, the present invention proposes an anti-entanglement spinning device and method for aramid silk fiber weaving to solve the above problems. Summary of the invention
