The invention aims to provide an electrostatic spinning device for preparing micro / nano composite fiber, and in particular relates to a split type composite electrostatic spinning device, specifically a device suitable for all types of composite electrostatic spinning. The split type composite electrostatic spinning device comprises a sealing cover, a core, a shell, an outer spinning nozzle, an inner spinning needle head and a fixed sealing gasket, wherein the shell is cylindrical, the outer spinning nozzle is installed at one end of the shell, the other end of the shell is connected with the sealing cover, the core is installed in the shell, the fixed sealing gasket is lined between the core and one end of the shell where the outer spinning nozzle is installed, at least one inner spinning needle head installing hole is formed on the core, and the inner spinning needle head is installed in the inner spinning needle head installing hole of the core. The invention solves the problem that the prior art can not adapt to complex replacement of multiple varieties and multiple specifications of composite electrostatic spinning and devices, and overcomes the defect of difficulty in maintenance in the prior art.

Description

technical field [0001] The invention relates to an electrospinning device for preparing micro / nano composite fibers, in particular to a split-type composite electrospinning device, in particular to a device adaptable to various composite electrospinning. Background technique [0002] Common electrospinning is to inject the polymer solution into the capillary, and add high voltage to the polymer to form a high voltage electric field between it and the grounded receiving screen. When the magnitude of the electric field force is equal to the surface tension of the liquid or melt, the charged droplet is in equilibrium at the end of the capillary. With the increase of the electric field force, the droplet is elongated into a filament. Due to the instability of the interaction between the charges, the filament is in a conical motion state during the falling process, and is collected on the fiber receiving device in the form of non-woven fabric. . [0003] However, the ordinary e...
