Problems solved by technology

There are the following technical defects in this preparation process: (1) The nanofibers produced by the electrospinning equipment naturally descend to the collection base by gravity, the collection base is in the shape of a flat disc, and the fibers are piled up on the collection base in a disorderly manner , it is very easy to cause the mixing of the fiber filaments, and the winding fluency of the nanofiber filaments is low
(2) The supporting drying equipment in the electrospinning equipment mostly adopts a single heat conduction form of heat convection or heat radiation to dry the fiber filaments, and the drying uniformity is poor; The internal volume of the drying device is not fully utilized, the drying efficiency is low, and it is not suitable for drying nanofiber tows with small diameters
(4) For electrospinning transportation, due to the small diameter of the nanofibers, the conventional rollers cannot fix the nanofibers, and the fibers and the rollers are prone to slipping during the transportation process, which affects the smoothness of the rollers.
(5) In order to protect the mechanical strength of nanofibers during transportation, and prevent the fibers from being pulled tightly or loosely due to factors such as friction during long-distance transportation, resulting in fiber breakage or mixing, now It is impossible to adjust the tension state of the fiber in some roller structures

Description

technical field [0001] The invention belongs to the field of nanofiber production equipment, in particular to nanofiber electrostatic spinning equipment. Background technique [0002] Nanomaterials refer to materials with at least one dimension in nanometer size (0.1-100 nm) or composed of them as basic units in three-dimensional space, which is approximately equivalent to the scale of 10-100 atoms closely arranged together. In nanomaterials, nanofibers refer to ultrafine fibers with a fiber diameter of less than 1000 nanometers. There are many methods for fabricating nanofibers, such as stretching method, template synthesis, self-assembly, microphase separation, electrospinning, etc. Among them, the electrospinning method is widely used due to its advantages of simple operation, wide application range and relatively high production efficiency. [0003] Electrospinning is a special fiber manufacturing process in which a polymer solution or melt is jet-spun in a strong elec...
