Block distributed type multi-printing-head 3D printing device with parallel-connection transverse beams and printing method

Abstract

The invention discloses a block distributed type multi-printing-head 3D printing device with parallel-connection transverse beams and a printing method and relates to the technical field of building construction. The problems of low working efficiency and accuracy of a single printing head of an existing 3D printing device are solved. The block distributed type multi-printing-head 3D printing device with the parallel-connection transverse beams comprises climbing members capable of vertically and gradually moving relative to an already printed building and a printing device body connected with the climbing members. The printing device body comprises a track framework and the printing head transverse beams. The two ends of the multiple printing head transverse beams in each lattice unit can slide along the latticed track framework, printing heads move along the printing head transverse beams and spray out building materials, the printing head transverse beams move along the track framework by a set distance each time printing of one line is finished, and in this way, the printing construction of current cross section layers is finished line by line. Climbing guide ways are lengthened to reach a preset height, the printing device body is jacked to the height where an upper to-be-printed cross section layer of the building is located by controlling the climbing members, and accordingly, all cross section layers are printed layer by layer from bottom to top till the printing construction of the whole building is finished.

Description

Technical field [0001] The invention relates to the technical field of building construction, in particular to a block-distributed multi-print head beam parallel type 3D printing device and a printing method. Background technique [0002] 3D printing buildings have the advantages of high degree of automation, one-time molding, and low construction materials and process losses. However, the existing 3D printing device uses a single print head, which is only suitable for the construction of small buildings such as residential buildings and small venues. For the construction of huge buildings, it is not only inapplicable, but also inefficient. Therefore, how to provide a block-distributed multi-print head beam parallel 3D printing device and printing method that has high printing efficiency, high printing accuracy, and can adapt to the construction of large-scale buildings is a technology that those skilled in the art urgently need to solve problem. Summary of the invention [0003...

Problems solved by technology

[0003] Aiming at the problem that the single print head of the existing 3D printing device has low working efficiency and cannot meet the construction needs of large-scale buildings, the purpose of the present invention is to provide a block-distributed multi-print head beam parallel-connected 3D printing device and printing method , the 3D printing device divides the track frame composed of track beams and connecting beams into several blocks with equal areas, and at least two print head beams are arranged in each block, and all print head beams in the same block are parallel It is arranged at intervals, and its two ends are respectively connected by a pair of parallel connecting plates, so that all the print head beams in the same block move synchronously along the track beams. By dividing the track frame into blocks, each block Multiple print head beams are set in one block, which not only improves the printing accuracy by shortening the printing range of a single print head, but also increases the number of print heads by increasing the print head beam, which improves the printing work efficiency
