The application relates to a free liquid
surface type electrostatic
spinning device which comprises a high-
voltage generator, two supporting frames, a
liquid drop platform, a plurality of groups of
jet flow generating devices, a collecting plate and a liquid supply device; the two supporting frames are symmetrically fixed on the high-
voltage generator; the
liquid drop platform is slidingly installed between the two supporting frames, and the top surface of the
liquid drop platform is provided with a plurality of grooves; the plurality of groups of
jet flow generating devices are arranged between the two supporting frames and correspond to the plurality of grooves; the collecting plate is arranged directly above the plurality of groups of
jet flow generating devices; and the liquid supply device is connected with a liquid inlet pipeline. After the
spinning liquid drops from the liquid outlet pipeline, the
spinning liquid falls on the
metal wires to form free
liquid surfaces; under the action of the
electric field between the
metal wires and the collecting plate, a
large range of nanometer and
micrometer fibers are deposited on the collecting plate, the amount of spun
yarn is large, the production efficiency is high, a relatively long distance can be ensured between the
metal wires to avoid the interference of the
electric field, and the stability of
fiber forming and spinning is ensured.
