Dismountable easy-to-clean pipeline system for conveying building 3D printing material

Abstract

The invention discloses a dismountable easy-to-clean pipeline system for conveying a building 3D printing material. The system comprises two first guide rail mechanisms, two second guide rail mechanisms, a third guide rail mechanism, a fourth guide rail mechanism, a first connection mechanism, a second connection mechanism and a plurality of feeding pipes, wherein the two first guide rail mechanisms are arranged parallel to a first horizontal direction; the two second guide rail mechanisms are arranged along a vertical direction and are respectively connected with the two first guide rail mechanisms in a sliding manner along the first horizontal direction; the third guide rail mechanism is arranged along a second horizontal direction vertical to the first horizontal direction, is erected between the two second guide rail mechanisms and is connected with the two second guide rail mechanisms in a sliding manner along the vertical direction; the fourth guide rail mechanism is arranged along the second horizontal direction, is arranged at the upper part of the third guide rail mechanism and is fixedly connected between the two second guide rail mechanisms; the first connection mechanism is connected with a printer head and is connected with the third guide rail mechanism in a sliding manner along the second horizontal direction; the second connection mechanism is connected with the fourth guide rail mechanism; the feeding pipes are connected with each other via a bent pipe bearing, are communicated with the printer head and are used for conveying the printing material to the printer head; the feeding pipes are connected with each other via the bent pipe bearing, so that the feeding pipes are capable of freely rotating and are low in possibility of damage.

Description

technical field [0001] The invention relates to the technical field of 3D printer manufacturing, in particular to a detachable and easy-to-clean pipeline system that can be used to transport building 3D printing materials. Background technique [0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses cumulative manufacturing technology, that is, rapid prototyping technology. 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. At this stage, 3D printers are mostly used to manufacture products. [0003] The 3D printer mainly includes a printing structure (print head), a forming printing table (on which the product is formed), and a printing head displacement adjustment mechanism (which can change the position of the printing head in spa...

Problems solved by technology

However, since the printing material is based on cement mortar and mixed with various admixtures at the same time, it is a quick-setting material with the characteristics of high viscosity and short initial setting time, and it is prone to pipe blockage during transportation. There are certain requirements for the bending radius of the delivery pipeline and the pumping pressure of the mortar pump

In the existing technology, hoses are usually used as the delivery pipeline, but once the printing material is blocked, the entire pipeline will be scrapped
