AI Technical Summary

Technical Problem

The raw material hopper of existing clay 3D printers is prone to clogging due to the stickiness of clay, making material discharge difficult and causing high wear and tear on the auger, which affects the stable operation of the equipment.

Method used

Design an eccentric powder quantitative conveying device, including a mixing chamber and a spiral auger set between a first chamber and a second chamber. The mixing chamber is provided with an inlet and an outlet. The spiral auger is set at an inclination. The pitch and blade diameter of the spiral auger are larger at the end near the inlet and smaller at the end away from the inlet to prevent blockage and achieve quantitative conveying.

Benefits of technology

It effectively prevents clogging of ceramic clay, reduces the load on the auger, ensures stable operation of the equipment, and achieves quantitative conveying. It has a simple structure and strong practicality.
