Turn-off control device for electric spinning direct-writing jet printing

Abstract

The invention provides a turn-off control device for electric spinning direct-writing jet printing, relates to an inkjet printing auxiliary device, and provides the turn-off control device for electric spinning direct-writing jet printing, which is capable of realizing the quick and accurate turn-off of electric spinning direct-writing jet printing flow. The turn-off control device is provided with a sprayer, a conductive relay, a power-supply high-voltage relay, a direct-current high-voltage power supply, a grounded high-voltage relay, a grounded relay, a delay relay, a collecting platform, a heating wire, a mechanical turn-off valve block, a heating direct-current power supply, a mechanical turn-off valve block turntable, a temperature-control relay, a current-limiting resistor, a mechanical turn-off valve starting limiter, a mechanical turn-off valve stopping limiter, a bracket, a three-end direct-current power pack, a motor, a protecting resistor, an electronic control single-pole three-throw switch and a controller. The sprayer is externally connected with a liquid supply device through a liquid supply pipeline.

Description

technical field [0001] The invention relates to an auxiliary inkjet printing device, in particular to an electrospinning direct writing jet printing shutdown control device. Background technique [0002] Electrospinning direct writing technology, as a new type of inkjet printing method, realizes the orderly preparation of nanofibers or micron films with a line width of 50nm-10μm by using the linear and stable stage of the spinning jet, with a positioning accuracy of 6-8μm and the highest inkjet printing The speed can reach 4m / s, and various solutions such as polymers and metal particle solutions can be directly spray-printed onto rigid or flexible substrates under normal temperature and pressure; it has good compatibility with flexible electronic materials and can be used with roll-to-roll The combination of roll-to-roll fabrication processes enables large-area, batch-scale, and low-cost fabrication of flexible electronics and organic micro-nano devices. Electrospinning dir...

AI Technical Summary

Problems solved by technology

[0005] At present, the shutdown of the spinning jet still mainly depends on the natural shutdown of the jet, which has a long shutdown time and poor control effect; there is no literature report on the control of the rapid shutdown of the spinning jet.
