Embodiment Construction

[0014] Such as figure 1 In the structure of the four-roller ultra-large draft compact spinning device shown, the rear roller 16 and the rear top roller 15 form the rear drafting roller pair; The drafting roller pair, the narrow groove type negative pressure front bottom roller 5 is a steel hollow roller with a large diameter. The surface of the roller has narrow grooves arranged according to certain rules, and it automatically rotates at the speed specified by the drafting multiple, which looks like a small dust. The cage is equipped with a suction component 6 inside, and has concave-convex grooves on the surface, which can effectively improve the holding effect on the fibers and prevent the adhesion of the fibers. The hole sucks the airflow, so that the fibers in the gathering area are gathered, and the gathered strands are twisted after exiting the twist-resistance nip, and the drafting and twisting process is completed. In order to achieve the effect of "complete accumulat...

Abstract

The invention discloses a four-roller oversized drafting compact spinning device which comprises a back drafting roller pair, a front drafting roller pair, a middle/back/front drafting roller pair and a middle drafting roller pair, wherein the back drafting roller pair consists of a back roller and a back leather roller, the front drafting roller pair consists of a narrow groove type negative pressure front/lower roller, a front leather roller and a twisting-resistant leather roller, the middle/back/front drafting roller pair consists of a middle/back roller and a middle/back leather roller, the middle drafting roller pair consists of a middle roller and a middle leather roller, and the middle/back roller in a four-roller drafting mechanism is the narrow groove type negative pressure roller. The conventional ring spinning is transformed form the structure of the device, so that the drafting times can be effectively improved, and the gross drafting times can be improved by more than 250 times, and the middle/back roller is replaced by the narrow groove type negative pressure roller, so that the drafting effect and the fiber collecting effect can be effectively improved. Furthermore, due to a cotton-collecting three-air way technology on a ring spinning frame, a collecting negative pressure fan which needs adding in the process of transforming can be eliminated, the energy consumption of a system can be reduced, the material consumption in the process of transforming can be reduced, and the transforming cost can be reduced; and compared with the other prior arts, the device is simple and convenient to install, and high in cost performance.

Description

technical field [0001] The invention relates to the new technology field of spinning, in particular to a novel four-roller type super-large draft compact spinning device. Background technique [0002] The drafting system is an important part of the spinning frame, and its performance directly affects the yarn quality. At present, the common spinning frame adopts the three-roller drafting form, including the common three-roller double-apron structure and the three-roller four-apron structure that can achieve 80-100 times larger draft. The ordinary three-roller double-apron structure is divided into two drafting areas: the front drafting area and the rear drafting area, and the rear area only uses simple rollers for drafting, so the friction force circle in the middle is relatively weak, and the draft ratio is generally less than 1.4 times, which is unfavorable to increase the total draft ratio of the spinning frame, so the total draft ratio is between 20 and 50. In order to...
