Abstract

The invention belongs to a drafting device for a ring spinning frame, and particularly relates to a back zone double apron drafting device for the ring spinning frame, which mainly solves the technical problems of easy generation of back roller torsional vibration, over-proof thick and thin joints, deteriorated evenness and small spinnable range existing in an existing drafting device. The technical scheme of the invention is that the back zone double apron drafting device for the ring spinning frame comprises a wedge groove type back roller sliding seat, a straight groove type back roller sliding seat, a wedge-shaped locating block, a fastening screw, a lower short apron, a small-gauge deformed section lower pin, a lower apron check block, a back claw pressurizer connecting block, a rolling tension bracket assembly, a tension bracket supporting shaft, a tension bracket supporting block, a lower long apron, a rocking bracket, a universal upper pin, an upper short apron, a back leather roller, a back roller, a back roller bearing, a horizontal moving slab, a roller stool and a thick yarn feed horn, wherein a wedge groove of the wedge groove type back roller sliding seat is internally provided with the small-gauge deformed section lower pin and the wedge-shaped locating block which are fixed by the fastening screw.

Description

technical field [0001] The invention belongs to drafting equipment for a ring spinning frame, in particular to a double apron drafting device in the rear area of ​​a ring spinning frame. Background technique [0002] At present, the rear area of ​​the ring spinning frame at home and abroad adopts the simple roller drafting form, and the rear area drafting undertakes a part of the spun yarn drafting and prepares for the front area drafting. The draft ratio in the rear area should not be too large, only less than 1.5 times. When the drafting ratio is large, the phenomenon of twist redistribution occurs, so that the friction circle in the middle of the sliver suddenly drops, which leads to the loose structure of the sliver, the speed change of the fiber in advance, and the deterioration of the evenness. Siro spinning and roving with a large twist coefficient, due to the large draft force directly acting on the surface of the back roller circle, will cause serious torsional vib...
