Abstract

The invention discloses an ink-jet device and a 3D printing device and relates to the technical field of 3D printing. A controller, a negative pressure box assembly, an ink storing box, a bottom plate and a plurality of spray head assemblies uniformly distributed on the bottom plate are included; each spray head assembly communicates with an ink supplying ink box assembly; each spray head assembly comprises a spray nozzle, an ink inlet and an ink returning port communicating with one another; the ink supplying ink box assembly comprises an ink supplying cavity and an in returning cavity; each ink inlet communicates with the ink supplying cavity, and each ink returning port communicates with the ink returning cavity; the negative pressure box assembly comprises a first cavity and a second cavity; the first cavity and the second cavity communicate with a negative pressure source so that the gas pressure in the first cavity can be larger than that in the second cavity; the first cavity communicates with the ink supplying cavity; the second cavity communicates with the ink returning cavity; and the ink supplying cavity and the ink returning cavity communicate with the ink storing box so that an ink circulating passageway of the ink storing box, the ink supplying cavity, the ink inlets, the ink returning ports and the ink returning cavity can be formed. The uniformity and the consistency of ink supplying can be improved, the ink jetting quality is improved, and then the printing effect is improved.

Description

Technical field [0001] The present invention relates to the field of 3D printing technology, in particular to an inkjet device and 3D printing equipment. Background technique [0002] Digital information and intelligence in the sand casting process are important directions for the development of sand casting technology. At present, the 3D printing forming technology of moldless sand mold has become a research hotspot of moldless sand mold manufacturing technology. The moldless sand 3D printer is suitable for product design, development and application, personalized customization, and multi-variety medium and small batch production, which can significantly shorten the product development cycle and reduce product mold development costs. [0003] At present, the inkjet device used in the sand 3D printing equipment has the phenomenon of frame loss or ink dripping during long-term use, which affects the actual printing effect. This phenomenon is particularly obvious for the nozzles arr...
