Problems solved by technology
[0004] On the one hand, due to the accumulation of electrostatic charges, these substrates will be tightly adhered to the receiving plate, increasing the friction between the substrate and the receiving plate, and the moving pulling force applied to the substrate during the continuous production process will Deformation or tearing of the receiving substrate resulting in damage or rupture of the nanofibrous membrane on the surface;
[0005] On the other hand, due to the natural bending of the soft substrate under the action of gravity, it will be separated from the receiving plate, resulting in poor contact and affecting the uniformity of the fiber membrane.

Abstract
The invention discloses an electrostatic spinning nanofiber membrane separation roller type continuous receiving method and a device thereof. The receiving method and the device realize receiving of a membrane by mainly adopting a bracket, a plurality of conductive separation rollers which are mounted on the bracket, and a substrate which is arranged below the bracket and is in contact with the separation rollers. The contact surfaces between all the separation rollers and the substrate are used for receiving most nanofibers to form separation strip-type membrane structures; continuous motion of the separation rollers and the substrate converts separation membranes into continuous membranes. According to electrostatic spinning separation roller type nanofiber membrane continuous receiving method and the device thereof, deformation and tear due to extremely high tension on the substrate in the conventional preparation method are avoided, good electric contact between the receiving substrate and the separation rollers is further guaranteed, and the continuity and the uniformity of the membranes are guaranteed. The device is simple in structure, realizes continuous receiving of electrostatic spinning nanofiber membranes, guarantees the completeness of the fiber membranes, and prevents the membranes from damage or breakage.
Description
technical field [0001] The invention relates to an electrospinning receiving method and device, in particular to an electrospinning discrete roller nanofiber membrane continuous receiving method and device thereof, belonging to the technical field of electrospinning. Background technique [0002] 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] The receiving method of the existing electrospinning technology to prepare the fiber membrane is generally to deposit the electrospin on the surface of a metal plate or cylinder, and then peel it off after the accumulation reaches a certain thickness. This method ...
