Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] refer to figure 1 and figure 2 The simplified schematic diagram of the process and structure shown in the present invention includes a double-nozzle concrete printing process, which includes the transmission of concrete slurry, foamed resin or (and) other necessary admixtures, the distribution of the printing process, and the concrete slurry. The transportation and addition of required additives, the printing and modification of building structural parts, the timely cleaning of the nozzles in the printing gap during the printing process, and the cleaning of the pipelines and nozzles after printing. Among them, the transmission of concrete slurry is realized by using the mixer 1 and the spraying equipment 3. After the cement, fine sand and water are fully stirred in the mixer 1, the opening and closing valve 2 is opened and the materials are dropped i...

Abstract

The invention belongs to the field of 3D printing, and in particular relates to a double-nozzle concrete printing device and a printing method. The device includes a three-axis motion platform, a nozzle device A, a nozzle device B, and blade stirring and blanking equipment located above the three-axis motion platform; the nozzle device A is used for spraying concrete slurry, and the nozzle device B is used for spraying foamed resin or Wet admixture, blade agitation and blanking equipment is used to add dry admixture to the workpiece to be printed; transmission of concrete slurry, foamed resin or (and) other necessary admixtures, distribution of printing process, concrete Transportation and addition of additives required in the slurry, printing and modification of architectural structural parts, cleaning in the nozzle between printing gaps, and cleaning after printing. The invention can realize high-efficiency rapid prototyping of large-scale building structural parts reinforced with different materials, fully consider printing accuracy and mechanical properties of building structural parts, and provide new technological ideas for the application of building materials in the field of additive manufacturing.

Description

technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a double-nozzle concrete printing device and a printing method. Background technique [0002] When 3D printing is applied to the construction field, there is no mature application-oriented process or equipment at present, and they are all in the laboratory stage. There are still a series of problems to be solved around materials, processes and equipment. In order to further improve the high-performance application of 3D printing in the construction field, the present invention proposes a dual-nozzle printing process, through which the high-speed and efficient multi-material complex structure molding of ordinary cement powder materials can be realized. Contents of the invention [0003] The object of the present invention is to provide a dual-nozzle concrete printing device and a printing method. [0004] The technical solution to achieve the purpose of the present invent...
