Abstract

The invention discloses a wool cleaning equipment based on machine vision, and relates to the field of textile technology. The technical problem to be solved is that in the production process of multi-axial acrylic fiber, the phenomenon that the yarn is not cut but wound on the drum often occurs. This causes uneven distribution of chopped strands and affects product quality. A central axis is arranged horizontally in the middle of the upper box. One end of the central axis is sealed and penetrates the upper box, and the other end is connected to the oxidation box through a bearing assembly. Several reels are arranged on the central axis. The reels can rotate on the central axis and their positions are limited by limiting blocks. The limiting blocks are arranged on both sides of the reel and are fixed on the central axis. The yarn in the tight state is always in a taut state, and the surface of the yarn is evenly oxidized. When the yarn is relaxed, it is easy to clean up the breakage caused by the oxidation process or when the yarn is wound on the drum. When the yarn is relaxed, There will be a gap between the yarns, and impurities such as broken threads will be cleaned away through the upper and lower rows.
