System for automatically cleaning tail yarns of roving bobbins

Abstract

The invention relates to a system for automatically cleaning tail yarns of roving bobbins. The system comprises a feeding device, a conveying device, an unwinding device, an opening device, a recovering device and a control system, wherein the feeding device is used for storing a plurality of roving bobbins of which large ends and small ends are respectively positioned in the same direction and which are wound with tail yarns and automatically conveying the roving bobbins to the unwinding device one by one; the unwinding device comprises a turnaround sliver cleaning mechanism, an unwinding mechanism, a successfully unwound roving bobbin collecting mechanism and an unsuccessfully unwound roving bobbin collecting mechanism; and the opening device is used for finding the ends of the tail yarns of the roving bobbins on the turnaround sliver cleaning mechanism and the unwinding mechanism and unwinding and opening the tail yarns. By matching the unwinding device, the opening device and the control system, the tail yarns of the roving bobbins are unwound and opened, the unwound roving bobbins are collected, or the roving bobbins which are not unwound or not completely unwound are collected, and the tail yarns are automatically cleaned in the whole process, so that a large amount of manpower is saved, and efficiency is improved.

Description

technical field [0001] The invention relates to a tail yarn cleaning device for roving bobbins. Background technique [0002] In the spinning process, the roving wound on the roving bobbin is drafted by the spinning machine to become a spun yarn that can be woven. However, due to the spinning process or spinning quality requirements, the last one or two layers of tail yarn wound on the roving bobbin cannot be fully used. At present, some cotton spinning mills adopt the method of cleaning tail yarns: cut the tail yarns of the roving bobbin with a manual hook knife to make them fall off, and use an opening machine to open the fallen tail yarns into usable cotton fibers. The processing method is labor-intensive and labor-intensive, and the short-lint rate of the cotton fibers that come out at the end will be significantly improved, reducing its utilization value. Contents of the invention [0003] The present invention solves the above-mentioned technical problems, and prov...

However, due to the spinning process or spinning quality requirements, the last one or two layers of tail yarn wound on the roving bobbin cannot be fully used

At present, some cotton spinning mills adopt the method of cleaning tail yarns: cut the tail yarns of the roving bobbin with a manual hook knife to make them fall off, and use an opening machine to open the fallen tail yarns into usable cotton fibers. The processing method is troublesome and labor-intensive, and the short-lint rate of the final cotton fiber will be significantly increased, reducing its use value
