Fiber collecting device for ring spinning frame

Abstract

The invention discloses a fiber nesting device for ring spinning frame, which comprises a front roller, a front leather roller, a nesting leather roller, and an indraft tube arranged under the nesting leather roller. An indraft groove is arranged on the top of said indraft tube, which slideably muffcouples a conveying belt, said conveying belt is driven by the front roller via belt driving unit or directly muffcoupled on the front roller. The fiber nesting device not only effectively avoids the spinning triangular space, but also ensures matching of the nipper jaws output speed with the conveying belt linear speed, so the resultant yarn quality is further improved.

Description

Technical field [0001] The invention relates to a ring spinning frame, in particular to a fiber strand gathering and compacting device in the drafting system of the ring spinning frame. Background technique [0002] In the traditional spinning system, when the fiber strands pass through the drafting system of the ring spinning machine in the rear area and the front area of ​​the drafting system and reach the nip of the front roller, the fiber strands are output to the twisting point where they are twisted into spun yarns. There is a spinning triangular area without twisting in between, because the fibers are basically out of control in this triangular area, especially the fibers at the edge of the triangular area cannot be gathered and twisted into the fiber bundle, and it is easy to leave and protrude from this area and become flying flowers And hairiness, together with the fact that the tension of the fibers in each part of the triangular area is not consistent, which ulti...

AI Technical Summary

Problems solved by technology

On the one hand, there are two stages of friction transmission in this device, and the power transmission is unreliable; on the other hand, because the accumulation top roller cannot provide enough pressing force, otherwise it will not only complicate the structure, but also may form a new Spinning triangular area, so it cannot provide enough frictional power to the conveyor belt, coupled with the influence of factors such as equipment vibration, it is difficult to keep the surface line speed of the conveyor belt stable and match the output speed of the front roller nip, so it is easy to form a pair of fibers Irregular and accidental drafting of strands will directly affect the yarn quality index
