Abstract

The invention discloses an electrostatic spinning injection device with a liquid preparation function. The electrostatic spinning injection device comprises an injection cylinder (3), an injection push rod (1), a needle (13), a liquid preparation cylinder (9) and a vacuum pump, the needle (13) is arranged at the end of the injection cylinder (3), the injection push rod (1) is arranged in the injection cylinder (3), and a pipe plug (11) is arranged at the end of the injection push rod (1), one end of the liquid preparation cylinder (9) is connected with the vacuum pump, the other end of the liquid preparation cylinder (9) is communicated with a cavity of the injection cylinder (3) through a liquid guide pipe (10), and a ball valve (2) is arranged at the outlet end of the liquid preparationcylinder (9). By means of the electrostatic spinning injection device, a liquid preparation device and an injection device are combined into a whole, the manpower process is saved, and the quality ofspinning products is improved.

Description

Technical field [0001] The invention relates to an electrostatic spinning injection device, in particular to an electrostatic spinning injection device with a liquid dispensing function. Background technique [0002] Electrospinning technology has become the main way to prepare fiber materials due to its advantages of simple manufacturing equipment, easy-to-control process, low cost, and many kinds of spinnable materials. So far, fiber materials prepared by electrospinning technology have been widely used in the fields of filters, protective materials, biomedicine, catalysts, optoelectronic devices, sensors, and food engineering. At present, the configuration of the spinning solution and the electrospinning injection device are carried out separately, which requires many procedures and long processes, and wastes manpower. The design of the upper jet injection device with the integration of liquid preparation and injection can improve the efficiency of electrospinning. Summary of...
