Vibrating electrostatic spinning device for nano fiber

Abstract

The vibrating electrostatic spinning set for nanometer fiber includes one container for holding spinning solution or melt, one high voltage electrostatic generator, one ultrasonic generator, and one piezoelectric sensor. The container is one cubic liquid storage tank with upper opening; and the piezoelectric sensor is set in the bottom of the tank and connected with the ultrasonic generator outside the tank. Over the liquid storage tank, there are one nanometer fiber conveyer and one nanometer fiber receiver, the conveyer includes guide roll, earthed electrode and conducting plate connected to the earthed electrode to form the negative pole; one electrostatic field is formed between the negative pole and the solution or melt inside the tank connected through electric plate to the high voltage electrostatic generator; and the receiver is one receiving screen. The present invention is used for producing nanometer fiber and has high production efficiency.

Description

technical field [0001] The invention belongs to the fields of textiles and materials, and relates to an electrospinning device for nanofibers, in particular to a vibrating electrospinning device for producing nanofibers in large quantities. Background technique [0002] At present, the textile industry in various countries in the world still generally uses single-nozzle or multi-nozzle syringe spinning devices for electrospinning of nanofibers, such as Chinese patent application numbers ZL 200420107832.5, ZL200420020596.3, ZL 200320122276.4, ZL 200410025622.6, etc.; 美国专利US 6616435,US 6713011,US 6753454,US 6656394;世界专利WO 06043968,WO2005073441,WO 2005073442,WO 2006018838,WO 2006007287,WO 2005026398,WO 2005123995,WO 2004016839,WO 04074559,WO 0209288 A1,WO 2005099308,WO 2006049664 et al. [0003] Two kinds of electrospinning devices of prior art nanofibers as shown in Fig. 1, 2, wherein, Fig. 1 is a kind of single nozzle syringe type electrospinning dev...

Problems solved by technology

[0004] Its shortcoming is, because the aperture of the microporous needle 3' as the spinneret hole is small, it is very easy to be blocked, and needs frequent replacement and cleaning of the spinneret hole, and meanwhile, the microporous needle 3' is also difficult to clean, thus causing the The production efficiency of silk is low, and it is impossible to carry out large-scale production at all, let alone meet the requirements of product applications
