Abstract

The invention discloses a reducing spray head for building 3D printing. The reducing spray head comprises a rotary shifting disc, a bottom plate, four linear guide rails, four sliding blocks and four right-angle moving sheets; when relative rotation occurs between the rotary shifting disc and the bottom plate, the rotary shifting disc drives four driving parts to rotate synchronously through four driving grooves, and then drives the four sliding blocks to synchronously slide along the four linear guide rails, and the four sliding blocks drive the four right-angle moving sheets to synchronously make relative movement, thereby changing the size of a square nozzle by changing relative positions of the four right-angle moving sheets in a printing process. A large-area region is printed, the size of the square nozzle can be enlarged and a discharge speed is raised, so that no repeated printing is required, the dwell time of the reducing spray head at such place is not required to be prolonged, and the printing efficiency is improved accordingly.

Description

technical field [0001] The present invention relates to the field of architectural 3D printing, and more specifically, relates to a variable-diameter nozzle and extrusion device for architectural 3D printing, which are used for extruding and curing cement mortar masonry 3D printing. Background technique [0002] 3D printing technology is an additive manufacturing technology that directly manufactures three-dimensional structures from digital models. It originated in the 1980s and integrates cutting-edge technologies in many disciplines such as information technology, electromechanical control technology, and material science and technology. It has been successfully used In aerospace, automotive, biomedical and other industries. 3D printing technology has brought a new idea to the development and transformation of the construction industry, and has strong application potential in solving the problems of environmental pollution, resource waste, and shortage of human resources ...
