Needleless electrostatic spinning device

The invention relates to a needless electrostatic spinning device. The needless electrostatic spinning device is composed of a spinning jet, a reception electrode, a high voltage power supply, a solution tank used for storing polymer solution, a waste fluid slot, base materials, a winding system of the base materials and the like, or the needless electrostatic spinning device is composed of the spinning jet, the reception electrode, the high voltage power supply, the solution tank used for storing polymer solution, the waste fluid slot, base materials, the winding system of the base materials, a heating device, an electric heating control device thereof and the like. The spinning jet adopts a slit-type spinning jet. The spinning jet is integrally constituted through the tight fitting of a left semi-spinning jet and a right semi-spinning jet, and the left semi-spinning jet and the right semi-spinning jet are fastened through a threaded connector, or the spinning jet is constituted by a left spinning jet component, a right spinning jet component and a flow-equalizing grid plate clamping piece arranged between the left spinning jet component and the right left spinning jet component. According to the needless electrostatic spinning device, the slit-type spinning jet is adopted, assembly, disassembly and cleaning are convenient, nano fibers can be produced continuously and effectively, and the spinning efficiency is improved greatly; the needless electrostatic spinning device can be applied both to the electrostatic spinning of the polymer solution and to the electrostatic spinning of the polymer molten mass.
