Description

technical field [0001] The invention relates to a spinning device, in particular to an electrostatic spinning device for producing nanofibers. Background technique [0002] At present, the electrospinning methods commonly used by research institutions and production companies in various countries in the world are mainly single-nozzle syringe type or multi-nozzle syringe type top-down spinning devices, such as Chinese patent application numbers ZL 200420107832.5, ZL200420020596.3 、ZL 200320122276.4、ZL 200410025622.6等;美国专利US6616435,US6713011,US6753454,US6656394;世界专利WO06043968,WO 2005073441,WO 2005073442,WO 2006018838,WO 2006007287,WO 2005026398,WO 2005123995,WO 2004016839,WO04074559,WO 0209288 A1,WO 2005099308, WO 2006049664, etc. [0003] The main disadvantages of this top-down spinning method are: 1. The diameter of the spinneret hole is too small, generally between 0.1-2mm, and is limited by the flow rate, so the production efficiency is very low; In the case of fast spee...
