Print head self-cleaning and control system for architectural 3D printing

Abstract

The present invention provides a printing head self-cleaning and control system for building 3D printing, comprising: a printing head, including a silo and a printing head outlet located at the bottom of the silo, and the inside of the silo forms a A space for accommodating printing materials; a high-pressure water supply device, the first coil and the second coil are connected to the high-pressure water supply device, and the first coil and the second coil are fixed on the In the silo, the first coil is arranged in a ring with a plurality of first nozzles, and the second coil is arranged in a ring with a plurality of second nozzles facing the inner wall of the silo; the compressed air supply device , the compressed air supply device is connected with a third coil, and the third coil is annularly fixed in the silo, and the third coil is annularly arranged with a plurality of coils facing the silo. a third nozzle on the inner wall; and a remote control platform. The invention has a high degree of automation, can flush and dry the inner wall of the feed bin in time, and ensures the safety of the cleaning process.

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...
