An electrospinning solution fiber printing wire diameter control system and printer

Abstract

The invention discloses an electrospinning solution fiber printing filament diameter control system. An opening is arranged at the bottom of the working material cylinder, and the storage material cylinder is inserted into the inner cavity of the working material cylinder, and is driven to rotate by a rotating device; the side wall of the material storage cylinder is provided with a The liquid outlet hole, before starting to work, the space below the liquid outlet hole in the storage cylinder is used to hold the material solution; the rotation speed of the storage cylinder is controlled by the rotating device. The higher the rotation speed, the higher the material solution rises on the cylinder wall. When the material solution rises to the liquid outlet hole, it is subjected to centrifugal force, detached from the storage barrel, reaches the working barrel, and flows out from the opening at the bottom of the working barrel to form spinning. By adjusting the rotation speed of the storage cylinder to change the amount of liquid supplied to the working cylinder, the control of the spinning diameter is realized; the material solution enters the working cylinder only when it is in use, so as to avoid long-term spinning utilization and untimely use at the printing nozzle and work The accumulation and adhesion of the barrel wall will cause waste of materials and corrosion of the working barrel.

Description

technical field [0001] The invention relates to the technical field of electronic manufacturing, and further relates to an electrospinning solution fiber printing wire diameter control system. In addition, the present invention also relates to a printer. Background technique [0002] Electrospinning technology is an inkjet printing method in which fibers are sprayed from a polymer solution and deposited on a substrate under the action of an electrostatic field. The sub-nanometer ultrafine fibers produced by electrospinning have a high Porosity and large specific surface area, as well as excellent electrical, mechanical, optical and other properties, are widely used in biology, chemistry, medicine and other fields. [0003] The spinning diameter formed by electrospinning is very small, and only a small amount of solution is needed to complete the printing. Therefore, the solution is usually put into the liquid nozzle at one time before printing. The time of electrospinning i...

AI Technical Summary

Problems solved by technology

[0003] The spinning diameter formed by electrospinning is very small, and only a small amount of solution is needed to complete the printing. Therefore, the solution is usually put into the liquid nozzle at one time before printing. The time of electrospinning is very long, usually up to more than ten For more than an hour, the solution is in contact with the outside air in the nozzle for a long time, and it is easy to oxidize and deteriorate on the inner wall of the nozzle, resulting in material waste and even printing failure

[0004] For those skilled in the art, how to avoid the problem of oxidative deterioration caused by long-term accumulation of solutions is a technical problem that needs to be solved at present.
