AI Technical Summary

Technical Problem

Existing concrete 3D printing equipment fails to monitor the fluidity and setting properties of concrete slurry in real time during processing, resulting in poor quality of the molded products.

Method used

By monitoring the pressure values ​​at the front and rear ends of the pumping device, and based on the pump speed, real-time control of the fluidity and setting properties of the concrete slurry is achieved.

Benefits of technology

It enables real-time monitoring and adjustment of slurry fluidity and solidification during concrete 3D printing, ensuring the quality stability and consistency of the molded products.

Abstract

This application discloses a concrete printing device, its control method, and a readable storage medium. The application relates to the field of concrete 3D printing technology. The control method for the concrete printing device includes the following steps: generating a first start signal; controlling the pumping motor of the pumping device to operate at a first speed according to the first start signal, so as to pump concrete slurry through a pipeline to the print head; monitoring the front-end pressure value and the rear-end pressure value of the pumping device; obtaining the slurry flow rate value in the pipeline according to the front-end pressure value and the rear-end pressure value; adjusting the first speed according to the slurry flow rate value so that the slurry flow rate value is within a preset flow rate range. This application can improve the molding quality of concrete 3D printed products.
