Full-automatic drawing frame

Abstract

The invention provides a full-automatic drawing frame, and belongs to the technical field of textile machinery. The drawing frame comprises a drawing frame rack, a feeding device, a drafting device, a slivering device, a sliver pulling device, a doffing guide device and a bobbin replacing device; the sliver pulling device comprises a sliver pulling mechanism and a sliver pulling guide mechanism; the sliver pulling mechanism comprises a fixed sliver pulling assembly and a movable sliver pulling assembly; a fixed sliver pulling curtain and a movable sliver pulling curtain are both provided with gathering protruding strips which are inclined inwards; the bobbin replacing device comprises a U-shaped bobbin replacing table, a bobbin feeding roller, a bobbin rotating mechanism and a bobbin replacing mechanism; and the bobbin replacing mechanism comprises a bobbin replacing rotating disc, a bobbin replacing rotating disc supporting shaft, a bobbin replacing arc-shaped arm, a bobbin replacing pressing wheel assembly, a bobbin replacing motor, a first bobbin replacing bevel gear and a second bobbin replacing bevel gear. In the drawing process, slivers can be effectively prevented from deviating, the drawing effect is guaranteed, and automatic bobbin replacing after drawing can be achieved; and the structure is ingenious, the automation degree is high, and the drawing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a fully automatic drawing frame. Background technique [0002] Textile machinery is all kinds of mechanical equipment needed to process natural fibers or chemical fibers into textiles. The processes required to process different fibers such as cotton, hemp, silk, wool, etc. into textiles are not the same, and some are completely different, so the machines required are also various and varied. Textile machinery is usually classified according to the production process, including: spinning equipment, weaving equipment, printing and dyeing equipment, finishing equipment, chemical fiber spinning equipment, reeling equipment and non-woven fabric equipment. Spinning equipment is divided into two categories: processing short fibers and processing long fibers. [0003] Common textile equipment are: carding machine, combing machine, drawing frame, roving frame, spinning frame,...

AI Technical Summary

Problems solved by technology

[0004] At present, the common drawing frame structure is relatively complex, and in the drawing process, the sliver is easy to shift, which seriously affects the drawing effect, and even causes the drawing failure

Moreover, the drawn sliver needs to be installed in the bobbin, and the bobbin needs to be replaced manually after being filled, which is time-consuming and laborious
