A funnel-type air-jet spinning device

Abstract

Provided is a funnel-type jet spinning device. The funnel-type jet spinning device comprises an ejection unit and a receiving unit. The receiving unit is vertically arranged above the ejection unit. The ejection unit comprises a liquid storage pool, a material barrel, a high-voltage power supply device and an air pump; the material barrel is arranged in the liquid storage pool and the bottom of the material barrel is provided with a funnel-type nozzle; the periphery of the inner wall of the material barrel is attached to a material conductive cooper sheet which is connected with the high-voltage power supply device located outside of the liquid storage pool; the bottom of the nozzle stretches into a circular-ring air-guiding pipe connected with the air pump outside the liquid storage pool; the receiving unit comprises a receiving board and a power supply negative pole; and the receiving board is connected with the power supply negative pole. The funnel-type jet spinning device has following beneficial effects: by adding the funnel-type nozzle on a conventional bubble spinning device, a bubble generation condition is greatly improved so that the quantity of spinning liquid flowing back to the air-guiding pipe is effectively reduced; a conduction mode utilizing metal wires is changed by conducing electricity with the metal cooper sheet around solution; and continuous, stable and uniformly-cracked bubbles cannot be formed during a bubble spinning process.

Description

technical field [0001] The invention relates to the field of spinning machinery and equipment, in particular to a funnel-type air-jet spinning device. Background technique [0002] Micro-nano fiber materials have a series of advantages such as small size, large specific surface area, and good fiber continuity, so they have broad application prospects in the fields of environmental sanitation, information technology, energy security, biomedicine, and national defense and military affairs. At present, electrospinning technology is recognized as the most effective method to quickly obtain micro-nano fibers with different diameters, shapes and functions due to its simple device and low cost, and is widely used. [0003] However, for the traditional single-needle or multi-needle electrospinning technology, it is difficult to meet the mass production of micro-nano fibers due to the disadvantages of easy clogging of the needles, difficulty in cleaning, and low yield. In order to o...

Problems solved by technology

However, the traditional bubble spinning technology sometimes cannot produce uniform bubbles that are continuously broken, so that an effective Taylor cone jet cannot be formed.
