Electrospinning equipment and its continuous nozzle with positive quadrangular platform and nine nozzles with auxiliary electrodes

Abstract

The invention discloses a spraying head for electrostatic spinning equipment. The spraying head comprises a body, wherein the body is provided with regular quadrangular frustum pyramid-shaped bases; the multiple bases are distributed along the axial direction; the lower bottom surfaces of any two adjacent bases are fitted in the axial direction; connection holes are respectively formed in two sides of the two fitted lower bottom surfaces; edge holes are formed in the vertex angles of edges of two sides of the lower bottom surfaces of the bases located at edges on two sides of the body; side edge holes are respectively formed in four side edges of each base; the heights of all the side edge holes are consistent; top end holes are formed in the central positions of the tops of the bases; the auxiliary electrodes with identical sizes are arranged in the edge holes, the side edge holes and the top end holes of the bases located at the edges on two sides of the body; nozzles with identical sizes are arranged in the connection holes and the side edge holes and the top end holes of other bases. The invention further discloses the electrostatic spinning equipment comprising the spraying head. According to the spraying head, a difference of the electric field intensity of each nozzle is relatively small, and a tip electric field is more uniform; furthermore, the spraying head has the outstanding advantage that the quantity of needle heads arranged within a unit area is larger.

Description

technical field [0001] The invention relates to the technical field of electrospinning, in particular to an electrospinning device with an auxiliary electrode positive quadrangular platform nine continuous nozzle nozzles. The present invention also relates to an electrospinning device having the continuous spray head with positive quadrangular platform and nine nozzles 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 ...
