Raw cotton foreign fiber sorting device and use method

The invention belongs to the technical field of computers, and particularly relates to a raw cotton foreign fiber sorting device and a use method. The sorting device comprises a device upper half part and a device lower half part, wherein the device upper half part is a raw cotton adsorption and transfer mechanism which is composed of three raw cotton adsorption heads arranged in a triangular central symmetry mode, a main shaft and a stepping motor are arranged in the center of the raw cotton adsorption and transfer mechanism, and the three raw cotton adsorption heads can conduct 120-degree single-time stepping rotation around the central main shaft; each raw cotton adsorption head comprises a raw cotton adsorption panel, a filter screen, a motor, a fan, a shell, an air inlet, an air outlet and a lifting mechanism capable of controlling the vertical height of the adsorption head. The raw cotton foreign fiber sorting device achieves full-automatic foreign fiber cleaning work, is high in efficiency and cleaning
