An electrospinning nozzle and an electrospinning device

Abstract

The invention discloses an electrostatic spinning nozzle and an electrostatic spinning device. The electrostatic spinning nozzle comprises a charging barrel for holding a melt spinning material, a first nozzle arranged at the bottom of the charging barrel, an opening formed in the top of the charging barrel and a temperature controlling device which is arranged at the periphery of the charging barrel and is used for controlling the ambient temperature in an injecting area of the first nozzle when the first nozzle injects the melt spinning material. According to the technical scheme disclosed by the application, the temperature controlling device is arranged at the periphery of the charging barrel contained in the electrostatic spinning nozzle and is used for controlling the ambient temperature in the injecting area of the first nozzle when the first nozzle injecting the melt spinning material, so that the influence of the ambient temperature on the melt spinning material is reduced. Therefore, compared with a mode of controlling the temperature of the whole electrostatic spinning device putted in a closed space, the electrostatic spinning nozzle has the advantages that the occupiedvolume for controlling the ambient temperature around the spinning material can be reduced, and energy consumption for controlling the ambient temperature around the spinning material can be reduced.

Description

Technical field [0001] The invention relates to the technical field of electrostatic spinning, and more specifically, to an electrostatic spinning nozzle and an electrostatic spinning device. Background technique [0002] Electrospinning is a process that uses polymer solution or melt to form jet stream under the action of strong electric field for spinning processing. In recent years, electrospinning has attracted widespread attention as a new processing technology that can prepare superfine fibers. [0003] In the process of melt electrospinning, the melt-like spinning material with a relatively high melting point ejected by the electrospinning nozzle will quickly cool down due to the large difference in temperature from the surrounding environment. The cooled spinning material The fluidity will be greatly reduced, which will eventually lead to the failure to normally prepare the specific nanofiber structure of the spinning material. In addition, in coaxial spinning, if the mel...

Problems solved by technology

However, since the entire electrospinning device needs to be placed in a closed space, the volume of the whole device will be relatively large, and since a temperature control device is required to control and maintain the temperature in the whole closed space, therefore, will increase energy consumption
