Needle plate reception device changes the field distribution of device for spinning by three-dimensional needle plate reception device, and fiber is easier to be gathered in potential
The three-dimensional fibre web of " tent-type " structure is formed at higher needle point to prepare fluffy nanofiber and improve its longitudinal compactness.
The technical solution adopted by the present invention to solve the technical problems is: providing one kind and is used to prepare fluffy electrostatic spinning and receives
The three-dimensional needle plate reception device of rice fibre web, including statitron and syringe, the syringe are connected with spinneret
Mouthful, the anode of the syringe needle connection statitron at the spinning nozzle, the spinning nozzle lower section is equipped with three-dimensional needle plate and connects
Receiving apparatus, the three-dimensional needle plate reception device are planted needle by metal plate, cystosepiment, masking foil and several metals and are composed,
The metal plate upper end is equipped with cystosepiment, and several metals plant needles penetrate cystosepiment vertically and are connected with metal plate, described
The outer surface of metal plate and cystosepiment covers one layer of masking foil, and the metal plants needle upper end and penetrates masking foil, the metal
Plate connects the cathode of statitron and ground connection.
As a supplement to the technical solution of the present invention, it is 13mm-19mm that the metal, which plants the height of needle,.
As a supplement to the technical solution of the present invention, it is 5mm-20mm that the metal, which plants needle gauge,.
As a supplement to the technical solution of the present invention, the spinning nozzle is to three-dimensional needle plate reception device bottom
The distance in portion is 140mm-200mm.
As a supplement to the technical solution of the present invention, every metal for penetrating masking foil and cystosepiment plants needle
Its height is all the same, and the potential that metal plants needle needle point is equal.
The utility model has the advantages that the present invention relates to a kind of three-dimensional needle plates for being used to prepare fluffy electrostatic spinning nano fibre web to receive dress
It sets, is planted due to metal and arrive distance of the distance between the spray head less than reception device bottom to spray head at needle needle point, so that at needle point
Potential it is higher, fiber can be easier to be gathered in first metal and plant position where needle needle point, when positively charged fiber connects
When contacting the negative electrical charge of needle point institute band, positive and negative charge is mutually neutralized, so that the fiber of jet stream head end is no longer by the effect of electric field force
Plant needle end is relied on, however fiber of the jet stream rear end with positive charge remains unchanged and is flown forward by the effect of electric field force, finally
Fall in the bottom of reception device.The three-dimensional fibre net structure of " tent " shape may finally be obtained, so as to improve the fluffy of fiber
Degree and porosity improve fibre web gas permeability, improve its longitudinal fine and close stacking.The present invention also has structure simple, easy to make,
The advantages that having a wide range of application.
