Abstract

The invention discloses a novel short-process melt electrostatic spinning instrument of an intelligent integrated 3D print platform. The novel short-process melt electrostatic spinning instrument of the intelligent integrated 3D print platform comprises a motor supporting frame, a motor, an insulated isolation plate, a second insulated isolation accessory, a gear, a FDM print wire rod reel and anelectrostatic field box. By the adoption of the 3D print adopting the fused deposition principle, a short-process hot fusing extrusion head system is simple in structure, easy to operate, low in cost,safe in operation and simple in aftertreatment, and by exerting high-voltage electricity, the obtained fiber has a micro-nano-scale feature; compared with existing electrostatic spinning, the novel short-process melt electrostatic spinning instrument of the intelligent integrated 3D print platform has the advantages that raw materials are universal 3D print consumables, by means of intelligent integrated combination of 3D print and the self-assembly electrostatic field, the formed fiber is controllable in morphology, an exhaust fan and an intake fan operate at the same time during air circulation, heat dissipation of the box body is achieved, after intake air is settled and dried, the intake air cannot influence material machining in the box body, and therefore the material quality can bebetter guaranteed.

[0002] Additive manufacturing technology, also known as 3D printing, is one of the main methods of material processing and molding. It is a fast and short process for realizing intelligence through computer-aided design, based on digital model files, and forming products according to the principle of layer-by-layer accumulation. Forming technology, but under the 3D printing technology, it is impossible to realize the micro-nano level control printing problem of the polymer melt. Therefore, by placing the melt of the 3D printing consumables under the condition of a high-voltage assembly electrostatic field, the short-process micro-nano level melt electrospinning can be realized. Silk, to avoid the disadvantages of polymer pellets due to different particle sizes, uneven feeding and long-term heating and aging of the spinning melt, resulting in differences in the diameter of the spinning fiber and mechanical properties. When printing, there is no air intake tube, only the gap To achieve air circulation, dust and moisture enter the box, and the heat dissipation effect is poor, which will affect the printing effect
