The invention provides a high-precision intelligent
down feather separation method and
system based on
structural difference driving, and relates to the technical field of
down feather separation. Dynamic humidification treatment is conducted on
down feather raw materials, so that the
water content of the
surface layer of a material curtain is stabilized within a
target range, then down
feather in the material curtain is blown up through a high-speed
air knife with a
fixed angle, and the down
feather separation efficiency is improved. The down
feather flocculus moves upwards close to the upper wall and finally hovers in a channel above a
wind field, a main
wind flow in the center directly blows out feather stems, a hologram of a material curtain is shot through polarization
laser, high-structure heterogeneous particles with the calculated confidence coefficient larger than a preset threshold value serve as candidate stem classes, a three-dimensional space coordinate
point set of the candidate stem classes is output, and the high-structure heterogeneous particles with the confidence coefficient larger than the preset threshold value serve as the candidate stem classes. Quantitative high-
voltage pulses are loaded according to the three-dimensional space coordinate
point set, the candidate stems are made to deflect and taken away by
airflow of the high-speed
air knife,
quality data of the down flowers are summarized into a report in real time to be transmitted back to a front-end
control system, the atomized water amount, the
air knife air pressure and the electrostatic
voltage are fed back and adjusted, and closed-loop
quality control from feeding to finished products is achieved.
