Automatic-rotating electrostatic spinning device assisted by high-pressure airflow and provided with nozzle

Abstract

The invention discloses an automatic-rotating electrostatic spinning device assisted by high-pressure airflow and provided with a nozzle and belongs to the field of electrostatic spinning. The automatic-rotating electrostatic spinning device mainly comprises a feeding device, an air compressor, the spinning nozzle, an electrode plate, a high-voltage electrostatic generator, a spread net belt, a hot roll and an air pumping system. The spinning nozzle is composed of a flow adjustment valve, a spinning nozzle body, a rotary body, a solution spinning rotating nozzle, a nozzle air cap and a feeding flow passage. With the high-pressure airflow principle of melt spinning and a centrifugal electrospinning device integrated, the automatic-rotating electrostatic spinning device solves the problem that a solution electrospinning single-spraying needle is low in efficiency and overcomes the defects that the diameter of fibers is too large and die head processing difficulty is large in the melt-blowing spinning method. The automatic-rotating electrostatic spinning device is designed in a detachable mode, can be maintained by replacing the nozzle, and is wide in application range and low in maintenance cost.

AI Technical Summary

Benefits of technology

This technology helps create an efficient way to produce fibers with excellent properties by combining different techniques such as melting blowing spun yarn or rotational spinning into one machine that works continuously without stopping down during repairs.

Problems solved by technology

This patented technical issue addressed in this patents relates to improving the performance of poly(micro)fibrils (PFF), specifically when they were made into products like medical devices. These PNF particles had unique properties compared to regular ones found naturally occurring because these molecules condense together without forming long chains along certain directions. They could be useful in making advanced applications where strength and durability cannot meet requirements. To overcome these issues, several methods involving combining multiple techniques including electrical charge transfer and mechanical twisting have been proposed over recent years.
