Printing head self-cleaning and control system for building 3D printing

Abstract

The invention provides a printing head self-cleaning and control system for building 3D printing. The printing head self-cleaning and control system comprises a printing head, a high-pressure water supply device, a compressed air supply device and a remote control platform, wherein the printing head comprises a stock bin and a printing head discharging port in the bottom end of the stock bin, anda space for containing a printing material is formed in the stock bin; the high-pressure water supply device is connected with a first coil pipe and a second coil pipe, the first coil pipe and the second coil pipe are both fixed in the stock bin, a plurality of first nozzles are annularly arranged on the first coil pipe, and a plurality of second nozzles facing the inner wall of the stock bin areannularly arranged on the second coil pipe; and the compressed air supply device is connected to a third coil, the third coil is annularly fixed in the stock bin, and a plurality of third nozzles facing the inner wall of the stock bin are annularly arranged on the third coil. The system is high in automation degree, the inner wall of the stock bin can be flushed and blown dry in time, and the safety of the cleaning process is ensured.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a printing head self-cleaning system for building 3D printing. Background technique [0002] 3D printing is a machine that utilizes cumulative manufacturing techniques, namely rapid prototyping. 3D printing technology is based on a digital model file, using adhesive materials as printing materials, and printing layers of adhesive materials to manufacture three-dimensional objects, that is, the technology of constructing objects by layer-by-layer printing. [0003] Architectural concrete 3D printing head device generally includes: power unit (motor, reducer, frequency converter, etc.), stirring shaft (screw conveying rod), material barrel, discharge pipe (variable diameter, variable cross section), concrete feeding pipe and other institutions. [0004] The printing materials used for architectural 3D printing have the characteristics of fast hardening and early str...
