Sharp tooth cage-shaped electrode electrostatic spinning device

The invention discloses a sharp tooth cage-shaped electrode electrostatic spinning device. The sharp tooth cage-shaped electrode electrostatic spinning device includes a sharp tooth cage-shaped electrode, a power supply, and a collecting device; the sharp tooth cage-shaped electrode includes two end plates and one or a plurality of sharp tooth linear type electrodes, the two end plates are provided with a rotation shaft, and the sharp tooth linear type electrodes are provided with a plurality of sharp teeth which are at a side edge away from the rotation shaft, have the identical distance relative to an axis of the rotation shaft, and are evenly distributed; and the power supply is electrically connected to the sharp tooth cage-shaped electrode and the collecting device, and an electric field required by jet flows is formed between all the sharp teeth and the collecting device after the power supply is on. The sharp tooth linear type electrodes can combined into the sharp tooth cage-shaped electrode, the structure is simple, the processing is convenient, and all the electrodes can be easily arranged on the same circle, so that the uniformity of the electric field can be ensured; and when the plurality of sharp tooth linear type electrodes are arranged between the two end plates, and uniform distribution operation of a solution on other sharp tooth linear type electrodes can be completed through rotation of the rotation shaft during spinning of one sharp tooth linear type electrode, so that spinning work can be continuously performed, and the efficiency of the spinning can be improved.
