Abstract

The invention discloses a building 3D printer follow-up trowelling mechanism which comprises a follow-up rotating mechanism, an automatic scraper blade height lifting mechanism, an adjustable scraperblade and a follow-up scraper blade control system, wherein the follow-up rotating mechanism is connected to a printing extruding machine, the automatic scraper blade height lifting mechanism is connected with the follow-up rotating mechanism, the adjustable scraper blade is connected to the automatic scraper blade height lifting mechanism, and the follow-up scraper blade control system is connected with the follow-up rotating mechanism to control an angle of the adjustable scraper blade. The building 3D printer follow-up flattening mechanism disclosed by the invention can automatically followa motion curve of a printer spray head to further rotate the position of the scraper blade in real time, so that the horizontal line of a vertical scraper blade face of the scraper blade is always parallel to a motion straight line curve or parallel to the tangential direction of a curve track; thus, a function of automatically flattening printing lines in a printing process is achieved, surfacequality of building 3D printer printing members is effectively improved, a subsequent manual modifying technology is reduced, and the efficiency of the 3D printer is improved.

Description

technical field [0001] The invention relates to the field of building 3D printers, in particular to a follow-up smoothing mechanism of a building 3D printer. Background technique [0002] At present, due to the influence of printing materials, architectural 3D printers have the problems of obvious printing layer pattern and rough printing surface. In the prior art, cylinder-driven scrapers are often used to smooth the outer surface of straight line sections, but for complex curve sections, The scraper cannot adjust the angle in real time to ensure that the scraper surface is parallel to the printing track or tangential direction, and cannot automatically and effectively complete the automatic smoothing function of the entire printing process. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a follow-up smoothing mechanism for a construction 3D printer, which can automatically follow the trajectory of the printer n...
