AI Technical Summary

Technical Problem

Existing powder spreading devices are unable to meet the powder spreading requirements of different ceramic and metal materials, resulting in poor printing efficiency and quality.

Method used

A powder spreading device was designed, including a powder hopper body, a powder blocking component, and a powder feeding shaft. By cooperating with the annular powder trough, the size of the powder feeding port can be adjusted to achieve quantitative powder feeding and flatness control, adapting to the powder spreading requirements of different materials.

Benefits of technology

It improves the practicality of the powder spreading device and the quality of printed products, ensuring the flatness of the powder material and the efficiency of powder spreading, and adapting to the printing requirements of various materials.

Abstract

This application relates to a powder spreading device, including a powder hopper body, a powder blocking component, and a powder feeding shaft. The powder hopper body has a powder feeding port at its bottom. The powder feeding shaft is rotatably disposed at the powder feeding port and extends along its length. The powder blocking component is movably disposed at the powder feeding port. The powder feeding shaft has multiple annular powder grooves spaced apart along its length. The powder blocking component cooperates with the annular powder grooves, and multiple fixed powder ports extending along the length of the powder feeding port are formed between the powder blocking component and each of the annular powder grooves. The powder feeding shaft rotates to allow powder from the powder hopper body to be spread onto the powder spreading surface through the fixed powder ports. Rotating the powder blocking component adjusts the size of the fixed powder ports. This application also relates to a 3D printing device. This solution addresses the difficulty in meeting the powder spreading requirements of existing 3D printers under different printing materials or operating conditions.
