Abstract

The invention discloses an electrostatic spinning multi-strand wire spray head, and belongs to the electrostatic spinning field. The spray head comprises a jointing piece, a guide piece and a heat control device, wherein the jointing piece is connected with the guide piece through screw thread; the heat control device is fixed on the outer surface of the jointing piece; the matched columnar surface of the guide piece is in tight fit joint with the corresponding surface of the jointing piece; a plurality of shunting holes are uniformly distributed at the lower end vertical to the columnar surface of the guide piece; a buffer groove is formed at the outlet of the shunting holes; a plurality of shunting grooves are annularly and uniformly distributed on the shunting conical surface of the lower end of the guide piece, and the shunting conical surface is parallel to the corresponding conical surface on the jointing piece; and the lower end of the guide piece is provided with an inner hexagonal hole and a shallow concave surface. The spray head used for electro-spinning of melt or solution can realize uniform preparation of multi-strand wires, and the combination of multiple spray heads with the structures can be introduced into a large-batch electrostatic spinning device; and the spray head greatly improves the production efficiency of electrostatic spinning, and reduces the processing cost of multiple spray heads.

Description

technical field

[0001] The invention relates to an electrostatic spinning device, which belongs to the field of electrostatic spinning. Background technique

[0002] The electrospinning process is to apply a high-voltage electrostatic field between the nozzle and the receiving device, so that the polarized fluid overcomes the surface tension under the action of the electric field force, forms a jet, and obtains ultra-fine fibers on the receiving plate.

[0003] With the heating up of nanotechnology, the preparation of nanofibers by electrospinning has become one of the current research hotspots. At present, fibers with a minimum diameter of tens of nanometers can be obtained. Therefore, considering how to increase production, it is inevitable to put electrospun nanofiber related products on the market. However, existing technologies are all in the laboratory stage, and mass-produced spinning machines have not yet come out. Most of the existing spinning equipment uses a si...
