Drawing frame

Abstract

The invention relates to a drawing frame. The drawing frame comprises a machine table, a merging device which is arranged on the machine table and used for merging a plurality of cotton slivers into one cotton sliver, a drafting device which is arranged on the machine table and used for stretching and thinning the merged cotton slivers, and a combining device which is arranged on the machine table and used for combining the drafted cotton slivers into one sliver, wherein the merging device comprises a roller plate arranged on the machine table, upper and lower pressing rollers which are arranged on one side of the roller plate, can rotate around the axes of themselves and have the circumferential outer walls close to each other, a roller distance adjusting mechanism which is arranged on the roller plate and controls the distance between the upper pressing roller and the lower pressing roller, a cotton separating box which is arranged on the machine table, located in front of the roller plate in the moving direction of the cotton slivers and used for the cotton slivers to enter, multiple cotton separating pieces arranged in the cotton separating box, and multiple sets of cotton separating needles which are densely arranged on the cotton separating pieces and stretch into the cotton slivers; and the sections, perpendicular to the moving direction of the cotton slivers, of the cotton separating needles are bent in a snake shape. The drawing frame has the effect of effectively pressing different cotton slivers.

Description

technical field [0001] The present application relates to the technical field of textile equipment, in particular to a draw frame. Background technique [0002] In the process of spinning cotton into cotton yarn, it is necessary to draw several slivers to obtain slivers that are evenly mixed and have good straightness. A draw frame is often used in the drawing step , the basic working sequence of the draw frame is merging, stacking several slivers and pressing them tightly; stretching, the sliver is elongated and thinned by two sets of rollers with different speeds, and finally the sliver is passed through the subsequent The coiler is placed in the sliver can. [0003] Existing draw frames often use rollers or pressure rollers to press different slivers together. [0004] With regard to the above-mentioned related technologies, the applicant believes that if different slivers are directly pressed together, it is difficult to combine the slivers into a whole, and there is a...
