Description
Technical Field
The invention relates to the field of new spinning technology, in particular to a fiber bundle gathering device in a compact spinning process and a using method thereof.
Background
In the normal spinning process of the ring spinning frame, a special problem exists in that the fiber bundle output from the front roller of the drafting zone is twisted and wound by the twisting and winding mechanism through the yarn guide hook, in the process, the twist generated by the twisting mechanism is transmitted upwards along the fiber strand, passes through the yarn guide hook, reaches the outlet of the front roller and forms a twisting triangular zone. Because the twist transmission path is too long, the control of the fibers in the fiber strand in the twisting triangular area is unstable, so that the yarn has more hairiness and uneven yarn strength, and the breakage is easy to occur in the production process.
The compact spinning device mainly gathers the fiber bundles under the action of airflow, reduces a twisting triangular space and greatly reduces yarn hairiness indexes. In the four-roller compact spinning, the fiber bundle output by the front roller is gathered under negative pressure before entering the output roller for twisting, and the fiber bundle is changed from a flat scattered shape into a linear shape which is gathered closely together, so that a twisting triangular area disappears at the output roller. For example, chinese patent CN103225144A discloses a method for applying a certain twist to drafted fiber strands by a pneumatic twisting mechanism to make the fiber strands gathered before entering an output roller, thereby reducing a twisting triangle, but in the implementation process, there still exist the problems of fiber strands being blown apart and blown disorderly, poor yarn formation, easy breakage, etc. Chinese patent CN1566425A discloses a negative pressure aggregation method of fiber strands by a grid ring, which is mainly characterized in that an air suction groove is formed on an air suction pipeline, a moving grid ring is sleeved on the surface of the air suction groove, and fiber bundles after drafting move to the air suction groove in the grid ring and are aggregated into bundles by negative pressure, so that the twisting triangular space is reduced in the twisting process, and the amount of harmful hairiness is reduced.
