Mechanical arm type cement product 3D printing machine

Abstract

The invention provides a mechanical arm type cement product 3D printing machine. The mechanical arm type cement product 3D printing machine comprises a printing spray head, and further comprises a supporting base with a traveling mechanism, a six-degree-of-freedom mechanical arm fixedly mounted on the supporting base, a cement storage tank mounted on the supporting base and a cement conveying mechanism used for conveying cement in the cement storage tank into the printing spray head. The printing spray head is fixed to the tail end of the six-degree-of-freedom mechanical arm and located on oneside of the supporting base and can move in the vertical plane perpendicular to the traveling direction of the traveling mechanism. The printing spray head comprises a cement delivery tube and a spray nozzle. A second conveying screw rod is rotatably mounted in the cement delivery tube. The usage convenience and the printing efficiency of the mechanical arm type cement product 3D printing machineare both improved.

Description

Technical field [0001] The invention relates to the field of cement product printing, in particular to a mechanical arm type cement product 3D printer, which is used for printing cement products, and is mainly used for printing cement sculptures. Background technique [0002] Three-dimensional printing (ie, three-dimensional printing) is a technology that builds objects based on digital model files and uses bondable materials such as powdered metal or plastic to print layer by layer. In the past, it was often used to make models in the fields of mold manufacturing, industrial design and so on. Now it is used in the direct manufacturing of cement products, such as the manufacture of cement sculpture products. [0003] A cement product 3D printer is a printer that uses three-dimensional printing technology to print cement sculpture products in the prior art. [0004] Most of the existing cement product 3D printers use a constructed frame for printing, that is, most of the existing cem...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing 3D printers for cement products use a constructed frame for printing, that is, most of the existing 3D printers for cement products need to pre-build the corresponding frame for the cement sculpture products to be printed, and the printing nozzles are based on the constructed frame. The frame is 3D printed, which is inconvenient to use

[0005] In addition, in view of the adhesiveness of cement materials, the nozzles of the printing nozzles of the existing 3D printers for cement products are easy to block, which restricts the printing efficiency of 3D printers for cement products to a certain extent.

[0006] In addition, for the existing 3D printers for cement products, when there are unsatisfactory prints during the cement printing process, it is necessary to find an additional trowel to correct the unsatisfactory printing, which restricts the 3D printers for cement products to a certain extent. printing efficiency
