Roving collector

Abstract

The invention discloses a roving collector in an n shape. The top (1) and the back at the lower end (2) of the roving collector are in concave arc shapes matched with rollers and intersect to form a solid angle, and an opening at the lower end (2) is in a horn shape. During production, the roving collector does not shake and is provided with good leading-in performance, during drafting, strips cannot fall off, the widths of the strips are unchanged, blocking cannot be caused, flying can be reduced, quality of yarns can be improved, the exchange operation is convenient, and cotton yarns cannot be broken.

Description

technical field [0001] The invention relates to a roving collector. Background technique [0002] On the traditional spinning machine, the width of the fed roving increases continuously during the drafting process, and the width of the sliver must be enlarged once without passing through the drafting rollers once; , as the draft ratio increases, the strands at the jaws of the front rollers become a broad belt shape, which destroys the contact between the fibers, and the fibers lose contact with each other. The rotating top rollers and rollers are curled, causing a large number of flying flowers to fall out; at the same time, the too wide strands sent by the drafting device will increase the difficulty of twisting, resulting in uneven dryness and fluffy appearance of the yarn; in addition, the old collection If the collector is used for too long, it will cause the mouth of the collector to silt up, and the collector will deviate and fall off.

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that the roving is too wide, the hairiness increases, the yarn dryness deteriorates, the mouth of the collector is silted up, and the sliver falls off when the roving enters the roller.
