Scraper structure of DLP ceramic printer

Abstract

The invention discloses a scraper structure of a DLP ceramic printer. The scraper structure comprises a working surface, wherein the working surface is provided with a rotatable resin groove, and thebottom of the rotatable resin groove is connected with a driving motor; the rear side of the rotatable resin groove is provided with an extension arm through a lifting device, and a forming substrateis arranged at the bottom of the extension arm; a scraper adjusting seat is arranged on the front side of the rotatable resin groove, a scraper leveling rod is arranged on the scraper adjusting seat,and the scraper leveling rod is provided with a scraper through extending downwards; the scraper adjusting seat comprises an L-shaped plate, wherein the bottom of the L-shaped plate is provided with an annular through groove, and the annular through groove is internally connected with a connecting piece; and a working surface is provided with a first fixing hole, the center of the annular throughgroove is provided with a rotating shaft through extending downwards, and the working surface is provided with a rotating hole. According to the scraper structure, the structure design is reasonable,through guiding action of the scraper, resin around the resin groove is filled into a vacant position after molding, the resin content for the next molding is guaranteed, and meanwhile, the leveling effect of the scraper is improved through rotating in a horizontal plane.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a scraper structure of a DLP ceramic printer. Background technique [0002] Digital Light Processing (Digital Light Processing, abbreviation: DLP) technology is a kind of 3D printing technology, which mainly uses ultraviolet light projected by a projector to solidify photosensitive polymer liquid layer by layer, thereby creating 3D printed objects. [0003] The DLP equipment includes a liquid tank, which is used to contain the photosensitive resin that can be cured after being irradiated by ultraviolet light of a specific wavelength; the imaging system is placed under the liquid tank, and its imaging surface is just at the bottom of the liquid tank. It can cure a thin layer of resin with a certain thickness and shape (the two-dimensional shape of this layer of resin after curing is exactly the same as the two-dimensional cross-sectional shape obtained by the previous cutting)...
