A rotating device for spraying nanofibers

Abstract

The invention discloses a rotation type device for spraying nanometer fibers. An inner material bin in the device comprises an outer device shell, an inner shell cavity and two or more spinning nozzles, the inner shell cavity is formed in the outer device shell, a spinning filament source is arranged inside the inner shell cavity, the spinning nozzles communicated with the inner shell cavity are connected to the side wall of the outer device shell, an upper heating device and a lower heating device are arranged at the top and the bottom of the outer device shell respectively, a longitudinal sliding groove is formed in the middle of the upper heating device and is in vertical and sliding fit with a sliding tube located inside the longitudinal sliding groove, the bottom end of the sliding tube penetrates through a material-containing top opening and then extends into the inner shell cavity, the top end of the sliding tube extends upwards to the part over the upper heating device, a tubecavity in the sliding tube is communicated with the inner shell cavity, and the bottom of the lower heating device is connected with the top end of a driving main shaft. In the design, the rotation type device is high in production efficiency, good in heating effect and collecting effect, high in adjustability and stability and diversified in product form.

Description

technical field [0001] The invention relates to a manufacturing device for textile silk, in particular to a rotary spraying device for producing nanofibers, which is particularly suitable for improving the production efficiency of nanofibers. 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, filter media, nanosensors, composite materials and other fields. [0003] The preparation of nanofibers has attracted the attention of experts and scholars at home and abroad. So far, there are many methods for preparing nanofibers, such as stretching method, microphase separation, template synthesis, self-assembly, electrospinning, etc. Among them, the electrospinn...
