Electro-spinning nano fibre nonwoven production apparatus

Abstract

The invention provides a production unit for mass producing electro-spinning nano fibre non-weaving cloth which includes: a meltdown pool 1, a metal roller 2, a receiving lace curtaining 3, a high voltage static generator 4, an initiative guide roll 51 and a passivity guide roll 52, a roller synchronous motor 62, a roller reductor 71, a roller belt pulley 72, a lace curtaining reductor 81, a lacecurtaining belt pulley 82, an earth metal plate 9. Four sides and bottom of the meltdown pool 1 is composed of a ceramic outside wall 13, a middle heating layer 12 and a ceramic inner wall 11, the sandwich design structure has better insulation effect and solves heating problem of polymer melt. Compared with prior electro-spinning mass production, the unit can satisfy melt electro-spinning need, and also can be used for solution electro-spinning for realizing multi-use of one machine.

Description

technical field [0001] The invention relates to an electrospinning device, in particular to a mass production device for melt and solution electrospinning nanofiber nonwoven fabrics. Background technique [0002] Nanofibers have fine structure, high porosity, excellent flexibility, adsorption, filterability, cohesion and thermal insulation. These excellent properties make nanofibers widely used in national defense, medicine, chemical industry and electronics, etc. Many fields. Electrospinning is currently one of the most effective technologies for preparing nanofibers. Its core is to make the charged spinning solution or melt flow and deform in an electric field, and then solidify through the evaporation of the solvent or the cooling of the melt to obtain a fibrous shape. Material. [0003] According to the preparation method of spinning solution, electrospinning can be divided into solution method and melting method. At present, nearly hundreds of polymers in the world h...

Problems solved by technology

However, the melt electrospinning technology has not made significant progress for more than 20 years, especially in its equipment, which basically uses a plunger type single nozzle spinning equipment, and the production rate is extremely low. So far, there is no suitable method at home and abroad. Electrospinning mass production equipment is mainly due to the need to add a melt heating device to the molten electrospinning liquid storage container, and its insulation control is difficult, especially the safety of mass production equipment has not found a better solution
