Description

Technical Field

[0001] The embodiments of the present application relate to the field of textile technology, and in particular to a fiber pulling device. Background Art

[0002] In the drafting device of the drawing frame, the pressure bar is widely used. Its function is to extend the friction force boundary of the drafting zone to the nip formed by the first roller and the first roller roller, so that the fiber is better controlled. The prior art is to install the pressure bar on the second roller bearing seat or the second roller roller bearing seat, so that the pressure bar forms a fixed position relationship with the second roller and the second roller roller in the main drafting zone. However, when processing fibers of different lengths, it is necessary to adjust the distance between the drafting rollers. In the design of the drafting device of the drawing frame, the first roller bearing seat is fixed, so adjusting the roller distance is to move the setting position of the second and third rollers. It is customary to call the distance between the first and second rollers the main drafting zone gauge, and the distance between the second and third rollers the back drafting zone gauge. Since in the prior art, the pressure bar is installed on the second roller bearing seat or the second roller roller bearing seat. Therefore, when adjusting the main drafting zone gauge, the relative position of the first roller and the pressure bar will also change with the movement of the second roller.

[0003] In recent years, due to the emphasis on environmental protection, the use of short fibers has increased in some yarn varieties. When processing raw materials with a high proportion of short fibers, controlling the movement of short fibers becomes the focus of the process during processing. In this way, the pressure bar needs to be closer to the gripping line formed by the first roller and the first roller leather roller. When using the existing technology, in order to obtain good control of this part of short fibers, it is necessary to adjust the distance between the first and second rollers to be very small, so as to achieve the purpose of making the pressure bar closer to the gripping line formed by the first roller and the first roller leather roller. However, there is still a large proportion of normal length fibers in the spinning raw materials. If the main drafting zone spacing is too small, the normal length fibers will not be effectively drafted, which will eventually affect the yarn quality. In order to solve the problem of effective drafting of normal length fibers, the solution using the existing technology is to increase the roller spacing in the main drafting zone. Since the pressure bar moves with the second roller bearing seat in the existing technology, when the roller spacing in the main drafting zone is increased, the pressure bar also moves away from the first roller. This will cause the pressure bar to lose its effective control over the short fibers. Utility Model Content
