Abstract

The invention discloses a quadrangular frustum pyramid interval array sprayer with auxiliary electrodes for electrostatic spinning equipment. The sprayer comprises a body, the body is provided with bases in a quadrangular frustum pyramid shape, and a plurality of bases are arranged in an array mode at intervals; connecting holes are formed in the four vertex angles of the lower bottom face of the base and the four vertex angles of the upper bottom face of the base; the bases at the edges of the two sides of the body and each connecting hole are all provided with the auxiliary electrodes of the same size, and the connecting holes of the other bases are all provided with nozzles of the same size. The invention further discloses the electrostatic spinning equipment of the quadrangular frustum pyramid interval array sprayer with the auxiliary electrodes. According to the quadrangular frustum pyramid interval array sprayer with the auxiliary electrodes for the electrostatic spinning equipment, each nozzle has relatively small differences in electric field strength, the tip electric field is more uniform, and the sprayer has the prominent advantage that the number of needle heads per unit area is larger.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to an array spray head with regular quadrangular truss spacers and auxiliary electrodes used for electrospinning equipment. The invention also relates to an electrospinning device with the regular quadrangular truss interval array nozzle with auxiliary electrodes. Background technique [0002] As we all know, electrospinning is a special fiber manufacturing process in which a polymer solution or melt is jet-spun in a strong electric field. Under the action of the electric field, the droplet at the needle will change from a spherical shape to a conical shape (that is, "Taylor cone"), and extend from the tip of the cone to obtain a fiber filament. In this way, polymer filaments with nanoscale diameters can be produced. [0003] In the prior art, for the array multi-nozzle electrospinning equipment, it uses a plurality of nozzles arranged in a linear rectangular array on the ...
