Description

technical field [0001] The invention belongs to the technical field of large-scale three-dimensional physical model preparation, and in particular relates to a large-scale complex geological physical model 3D forming system. Background technique [0002] Simulating the excavation process of natural rock mass engineering through physical model tests is an important method for predicting and forecasting large-scale rock mass engineering geological disasters. [0003] At present, large-scale physical models are usually made by pouring method, tamping method and small block masonry method, but the structure of the physical model made by these traditional methods is relatively simple, and it is impossible to make structures containing faults, folds and bedding inside. The physical model of the surface. 3D printing technology is a method of slicing complex objects layer by layer and then stacking them to form a complete object. Therefore, 3D printing technology provides a new way...

Problems solved by technology

[0010] Aiming at the problems existing in the prior art, the present invention provides a 3D molding system for a large complex geological physical model, which includes a newly designed 3D molding machine, a mixer, a feeding controller and a printing head; the 3D molding machine is suitable for cement, gypsum, Sand, iron powder, barite and other rock mass-like materials can be adjusted in the process of making physical models to meet the requirements of printing more than two kinds of materials at the same time; the mixer adopts the overall sealing design and adds dust removal function, It effectively avoids the floating dust generated by similar materials in the rock mass during the mixing process, and ensures the cleanness of the laboratory environment. The feeding and mixing of similar materials in the rock mass are fully automated without manual intervention, which effectively reduces the labor intensity of the operator. The filter function is added during the mixing process of similar rock mass materials, which effectively removes particles with larger particle sizes from similar rock mass materials, eliminates the problem of print head clogging, and ensures the continuity of printing work; the feeding controller can be used for Instead of the traditional screw conveyor and plunger conveyor, it can accurately control the output volume, and the output volume is adjustable. When the pumping work is over, the feeding controller can be disassembled, which is more convenient for cleaning ;The print head can quickly adjust the printing accuracy according to the actual printing needs. At the same time, it has the anti-clogging function of the print head. During the suspension of printing, the anti-clogging function of similar material circulation or the anti-clogging function of similar materials can be activated according to the length of the pause time. blocking function
