Description

Technical Field

[0001] The utility model relates to the technical field of drying, in particular to a microwave drying device for 3D printing materials of plastic materials. Background Art

[0002] After the printing filament is fused, it is conveyed to the print head, and a predetermined shape is printed through the print head. The printing filament is formed by drawing the 3D printing material of plastic materials. When there is moisture on the surface or inside of the 3D printing material of plastic materials, bubbles will appear in the made printing filament. After bubbles appear in the printing filament, defects will appear in the printed product. Therefore, it is necessary to ensure that there are no bubbles in the printing filament; the 3D printing material of plastic materials is in a granular or powdery structure. Therefore, it is necessary to dry the 3D printing material of plastic materials. The existing drying method is to dry the 3D printing material of plastic materials through hot air. Since the granular or powdery 3D printing material of plastic materials is piled up together, the drying effect of the granular materials inside and at the bottom is not good, or it takes a long time to dry, and the drying efficiency is low.

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0022] As Figures 1 to 4 shown, an embodiment of this application provides a microwave drying device for a plastic 3D printing material, including a stirring motor 10, a stirring barrel 20, a microwave magnetron 30, and a conductive ring 40; the main shaft 11 of the stirring motor 10 is fixedly connected to the stirring barrel 20, the microwave magnetron 30 is fixedly connected to the stirring barrel 20, the conductive ring 40 is sleeved outside the main shaft 11 of the stirring motor 10, and the conductive ring 40 is electrically connected to the microwave magnetron 30.

[0023] As Figures 1 to 4 shown, plastic 3D printing material particles are placed in the stirring barrel 20. The stirring motor 10 drives the stirring barrel 20 and the microwave magnetron 30 to rotate. One end of the conductive ring 40 is connected to an external power source, and the external power source supplies power to the microwave magnetron 30. The microwave emitted by the microwave magnetron 30 heats the plastic 3D printing material particles. During the rotation of the stirring barrel 20, the plastic 3D printing material particles can be heated evenly, preventing the accumulation of plastic 3D printing material particles, enabling the evaporation of moisture on the surface of the plastic 3D printing material particles, drying the plastic 3D printing material particles. When the plastic 3D printing material particles are dry, the plastic 3D printing material particles are fused and drawn into filaments, reducing the bubbles on the surface of the filamentous material.

[0024] As Figures 1 to 4As shown in the figure, the microwave drying equipment for the plastic 3D printing material further includes a fixing frame 50. The fixing frame 50 includes a fixing disk 51 and a number of fixing columns 52. The main shaft 11 of the stirring motor 10 is fixedly connected to the fixing disk 51. One end of the fixing column 52 is fixedly connected to the fixing disk 51, and the other end is fixedly connected to the stirring barrel 20. The fixing frame 50 plays a fixing role. The main shaft 11 of the stirring motor 10 drives the stirring barrel 20 to rotate through the fixing frame 50, and the microwave magnetron 30 rotates together with the stirring barrel 20.

[0025] As Figures 1 to 4 shown in the figure, the microwave magnetron 30 is arranged between a number of fixing columns 52, and the microwave antenna 31 of the microwave magnetron 30 extends into the stirring barrel 20. The microwave generated by the microwave antenna 31 can heat the plastic 3D printing material particles.

[0026] As Figures 1 to 4 shown in the figure, a microwave antenna cover 32 is provided outside the microwave antenna 31 of the microwave magnetron 30. The microwave antenna cover 32 prevents microwave leakage outside the stirring barrel 20.

[0027] As Figures 1 to 4 shown in the figure, the stirring barrel 20 includes a barrel body 21 and a barrel cover 22. The barrel cover 22 and the barrel body 21 are covered with each other. The barrel cover 22 is provided with a microwave leakage viewing window 23. The microwave leakage viewing window 23 can prevent microwave leakage outside the stirring barrel 20.

[0028] As Figures 1 to 4 shown in the figure, the barrel cover 22 is provided with an air outlet hole 24. The water vapor generated by heating can be discharged from the air outlet hole 24 to the outside of the stirring barrel 20.

[0029] As Figures 1 to 4 shown in the figure, the barrel body 21 is a polygonal structure. The barrel body 21 being a polygonal structure can more fully stir the plastic 3D printing material particles evenly.
