Abstract

The invention relates to the nanometer fiber manufacturing and weaving machinery field and especially relates to a blade printing type electrostatic spinning device and a using method thereof. The device comprises a liquid storage bottle and a liquid guide pipeline. The liquid guide pipeline is connected to a brush shaft arranged on a support frame. The brush shaft and a printing-type nozzle are connected through a bolt in a circular hole. A blade is arranged below the printing-type nozzle. The blade is arranged on a pedestal. The pedestal is provided with a track where a moving rack moves. The top end of the moving rack is fixed to the support frame and a bottom cross rod is connected to the output end of a motor II through a transmission mechanism. The anode of a high pressure generatoris connected to the blade through a bearing. The lower portion of the liquid guide pipeline is connected to a peristaltic pump. A metal roller is arranged above the support frame. A rotating shaft inthe metal roller is connected to a motor I through a shaft coupling. The other end of the metal roller is connected to a ground wire. The device can complete the automatic circulation supply of a spinning solution and the preparation of mass nanofibers, and the application of mass and industrialized nanofibers is realized.

Description

technical field [0001] The invention relates to the fields of nanofiber preparation and textile machinery, in particular to a blade-printed electrostatic spinning device and a use method thereof. Background technique [0002] Electrospinning is a simple and effective method to prepare nanofibers. The basic principle of electrospinning is that in the high-voltage electric field, the polymer solution droplets form a "Taylor cone" at the spinneret. In the electrostatic field, the polymer solution is subjected to electrostatic force in addition to the viscous stress. The polymer droplets The drawn jets form charged jets, and the drawn jets form randomly oriented nanofibers. Because of its simple principle and simple operation during the experiment, electrospinning nanofibers have been used in biomedicine, clothing, composite materials, filter materials and Sensors and other fields have become research hotspots. The application of nanofiber materials is very extensive, such as...
