The invention discloses a continuous liquid feeding electrostatic spinning device with a closeable liquid feed hole. The device comprises a power supply, a transmission system, multiple micro shafts, a motor, a motion platform, a liquid storage tank and a collection device, wherein multiple countersunk grooves are formed in positions, which correspond to the micro shafts, at the bottom of the liquid storage tank; a through hole is formed in each countersunk groove; each micro shaft penetrates through the through holes and penetrates out of the bottom of the liquid storage tank; gaps through which spinning solution flows are reserved between the micro shafts and the through holes; a plunger is arranged above the countersunk grooves on each micro shaft; when the micro shafts are lifted, the gaps can be opened or closed by matching of the plungers and the countersunk grooves, the power supply is respectively and conductively connected with each micro shaft and the collection device, and after the power supply is started, an electric field needed by jet flow can be formed between each micro shaft and the collection device. According to the device disclosed by the invention, the liquid storage tank is drilled and micro shafts are inserted into the liquid storage tank so as to form a coaxial structure, a Weissenberg effect principle is adopted, and the problems that the traditional hollow electrospinning nozzles are blocked, each nozzle liquid feed volume is difficult to control and the like are solved.
Description
technical field [0001] The invention is used in the technical field of electrospinning, and in particular relates to a continuous liquid supply electrospinning device with a liquid supply hole that can be closed. Background technique [0002] At present, nanofibers have been widely used in environmental protection, biomedicine and other fields, and the technology most used to produce nanofibers is electrospinning technology. This technology relies on the action of high-voltage electrostatic field to stretch and split the jet, and finally Methods of forming nanofibers. At present, the multi-nozzle electrospinning device used for mass production of nanofibers can produce fibers with uniform nanofiber diameter. Ultra-efficient air filtration membranes and other fields are widely accepted, but there are still many problems in the multi-nozzle electrospinning device of batch nanofibers, such as the inability to ensure the same liquid supply for each nozzle, the inability to cont...
