Abstract

The invention relates to a centrifugal spinning nozzle system for generating multiple fibers. The system comprises a material injection pipe, a spinning head, a driving pipe, an air containing hollowshell and at least two silk spraying pipes, wherein a material containing cavity is formed in the spinning head, silk spraying cavities are formed in the silk spraying pipes, the inner ends of the silk spraying pipes are connected with the side part of the spinning head, and silk spraying openings are formed in the outer ends of the silk spraying pipes and communicated with the material containingcavity through the silk spraying cavities; the air containing hollow shell comprises a left hollow shell part, a right hollow shell part and multiple empty shell fingers; a left air containing cavity, a right air containing cavity and air containing finger cavities are formed in the left hollow shell part, the right hollow shell part and the empty shell fingers respectively; a finger clamping cavity is formed between every two adjacent empty shell fingers, the corresponding silk spraying pipe is clamped in each finger clamping cavity, and air outlets communicated with the air containing finger cavities are formed in the outer side faces of the empty shell fingers. According to the design, not only is the manufacturing efficiency high, blockage is unlikely to happen, but also the guiding property is excellent, and the liquid state of a liquid material can be ensured.

Description

technical field [0001] The invention relates to a production device for superfine fibers, which belongs to the field of nanofiber manufacturing, and in particular to a centrifugal spinning nozzle system for generating multi-fibers, which is particularly suitable for improving manufacturing efficiency and is not prone to blockage. Background technique [0002] Nanofibers refer to ultrafine fibers with a diameter of tens to hundreds of nanometers, which have unique advantages that other fibers cannot possess, such as very large specific surface area, ultrafine porosity, and good mechanical properties. In recent years, nanofibers have been widely used in textile materials, tissue engineering scaffolds, drug delivery, filter media, artificial blood vessels, biochips, nanosensors, optics, composite materials and other fields. [0003] So far, there are many methods for preparing nanofibers, such as stretching, microphase separation, template synthesis, self-assembly, electrospinn...
