AI Technical Summary
Traditional manual sorting methods for foreign fibers in cashmere are time-consuming, labor-intensive, inefficient, and harmful to workers' health in a closed, dark environment, making it difficult to control quality.
An automated sorting device that combines fluorescence detection with positive pressure blowing and negative pressure extraction uses ultraviolet light beads to identify foreign fibers, blows them away through positive pressure nozzles and sucks them up through negative pressure ducts, achieving automated control and efficient sorting.
It has automated cashmere sorting, improved sorting efficiency and purity, protected worker health, and ensured sorting quality.

Abstract
Claims
1. A device for sorting of anisotropic fibers of cashmere, comprising a frame, inside which a conveyor belt is arranged, said conveyor belt is connected to a detection mechanism and a sorting mechanism, both of which are electrically connected to a PLC controller, characterized in that: The detection mechanism consists of multiple units arranged in a linear matrix, each unit including ultraviolet light beads and a camera; the sorting mechanism includes multiple positive pressure nozzles arranged in a linear matrix and a first strip shell with a volute cavity cross-section. The center of the first strip shell is a volute cavity opening and is connected to a negative pressure air duct. The outer side of the first strip shell is a volute cavity opening and is symmetrically arranged with the positive pressure nozzles about the normal of the conveyor belt.
2. The cashmere foreign fiber sorting device according to claim 1, characterized in that: The positive pressure nozzle is connected to a second strip shell via a branch pipe. The second strip shell has a spiral cavity with the same structure as the first strip shell. The central opening of the second strip shell is connected to the positive pressure air duct. A sealing plate is provided at the outer flared opening of the second strip shell. The branch pipe is connected to the sealing plate. The positive pressure air duct is connected to the first air pump. A high-speed air valve is provided on the branch pipe.
3. A cashmere fibre sorting device as claimed in claim 1, wherein: The conveyor belt is a breathable conveyor belt made of fiber woven belt, and a negative pressure box is set at the bottom of the conveyor belt. A hair-leveling rake or hair-guiding roller is set at the front end of the conveyor belt.
4. The cashmere foreign fiber sorting device according to claim 1, characterized in that: The negative pressure duct is connected to the first flow duct via a second air pump and is used to draw foreign fibers into the impurity bin; a negative pressure suction head is provided at the end of the conveyor belt and is connected to the second flow duct, which is used to draw the sorted cashmere into the clean bin, and a fan is provided at the upper inlet of the clean bin.
