The invention relates to the technical field of electrostatic
spinning and nanometer material systems, particularly relates to device for manufacturing nano-
fiber membranes on a large scale, and discloses a large-scale electrostatic
spinning machine which comprises a high-
voltage electrostatic source, a
spinning system with arrayed needles, a collecting
system and an
intelligent control system. The spinning system with the arrayed needles comprises a constant-flow pump module and a
yarn forming module, the
yarn forming module is connected with the constant-flow pump module, and an
anode of the high-
voltage electrostatic source is connected with the
yarn forming module; the collecting system comprises transmission modules, a membrane forming layer and a conducting layer, the membrane forming layer is connected with the transmission modules, the conducting layer is fixed to the lower side of the membrane forming layer, and a
cathode of the high-
voltage electrostatic source is connected with the conducting layer by a conducting wire; the
intelligent control system controls advancing and retreating actions of the constant-flow pump module, rotation and translation actions of the yarn forming module and
clockwise rotation and anticlockwise rotation actions of the transmission modules, so that the membrane forming layer can directionally move under the control of the
intelligent control system, fibers are collected, and membranes can be uniformly formed by the fibers. The large-scale electrostatic spinning
machine has the advantages that the large-scale electrostatic spinning
machine has low requirements on production conditions and the cost, is simple in operational process and high in production efficiency, and is intelligent and controllable, the texture of each membrane is uniform, and the like.
