Document Type and Number:
WIPO Patent Application WO/2022/160380
Kind Code:
A1
Abstract:
A multi-stage speed reduction extruder and a 3D printing device, related to the technical field of 3D printing. The multi-stage speed reduction extruder comprises a base, a driving motor, a speed reduction mechanism, and an extrusion mechanism. The speed reduction mechanism comprises a duplex gear and extrusion gears. The duplex gear is linkedly connected to a motor gear of the driving motor for performing first speed reduction. The extrusion gears comprise an active extrusion gear and a passive extrusion gear linkedly connected to the active extrusion gear. The active extrusion gear is linkedly connected to the duplex gear to perform a second speed reduction. The extrusion mechanism comprises extrusion rollers provided coaxially with the extrusion gears. A material feeding channel used for conveying a printing material is formed between the extrusion rollers. When the driving motor is working, the driving motor drives the reduction mechanism and the extrusion mechanism to rotate for conveying the printing material.
