Embodiment Construction

[0031] The invention discloses a bubble electrospinning device, which is used to solve the problems that the number of bubbles in the bubble generating device is small and the droplet is difficult to control in the spinning process. In this bubble electrospinning device, firstly, the bubble generating device is set as a mesh structure, which increases the number of polymer films, thereby increasing the number of bubbles and increasing the output; secondly, the blowing port at the front end of the blowing device is connected The corresponding mesh structure ensures that the polymer film on the mesh of the bubble generating device forms bubble protrusions; moreover, the airflow generated by the blowing device takes away the polymer droplets attached to the bubble generating device, making the receiving plate The fiber morphology is more uniform. The invention has the advantages of simple structure, convenient operation, simple control and short technological process.

Abstract

An air bubble electrostatic-spinning device comprises a liquid storage tank, a receiving plate, an air bubble generating device, a lifting line connected with the air bubble generating device, an air blowing device, a blowing device and a direct-current high-voltage power supply connected with a lifting line and the receiving plate. An air blowing port formed in the front end of the air blowing device of the air bubble generating device ensures that a high polymer film on meshes of the air bubble generating device form air bubble protrusions, and air flows produced by the blowing device carry away high polymer liquid drops attached to the air bubble generating device, so that fiber morphology on the receiving plate is more uniform. The air bubble electrostatic-spinning device is simple in structure, convenient to operate, simple in control and short in technological process.

Description

technical field [0001] The invention belongs to the field of spinning, in particular to a bubble electrostatic spinning device. Background technique [0002] Compared with traditional cotton, wool, silk, hemp and chemical fibers, nanofibers have a finer fiber diameter, thereby increasing the aspect ratio, surface area and porosity, and have extremely high surface activity. Therefore, nanofibers are used in textile engineering, Environmental engineering, tissue engineering, biomedicine and other fields have very broad applications. There are various methods and equipment for producing nanofibers, and electrospinning technology is the most direct and simple method for preparing nanofibers. Under the action of electrostatic force, nanofibers are obtained by stretching and thinning. [0003] However, the needle of the traditional electrospinning device is easy to block and difficult to clean, resulting in low output, which has become a major difficulty in mass production. At ...
