Lifting mechanism of 3D printer

Abstract

The invention provides a lifting mechanism of a 3D printer, and aims at solving the problem of poor lifting effect of the lifting mechanism in the prior art. The lifting mechanism of the 3D printer is characterized in that the 3D printer comprises a base, wherein a plurality of mounting holes in which vertical columns are fixed are formed in the base; an ink-jet printing head for printing is arranged between every two vertical columns; the lifting mechanism capable of controlling the ink-jet printing head to lift up or lift down is arranged between each ink-jet printing head and the corresponding vertical column; each lifting mechanism comprises three lifting tracks which are fixed to three vertical columns; three lifting blocks are correspondingly matched with the three lifting tracks; four pulleys which are in match with the lifting track sleeve the lifting block; each lifting block is provided with two outward bulging parts, and each bulging part is provided with a hinging hole; the lifting blocks can be hinged with the upper ends of control arms through first hinging columns; the lower ends of the control arms are connected to the corresponding ink-jet printing heads; a telescoping rod which can be telescoped is arranged in the middle of each control arm. The lifting mechanism of the 3D printer has the advantage that the lifting effect is good.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a lifting mechanism of a 3D printer. Background technique [0002] 3D printer, a machine of rapid prototyping technology, is a technology based on a digital model file, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacturing of some products, which means that this technology is becoming popular. [0003] At present, most of the nozzle transmission mechanisms of 3D printers on the market use the transmission mechanism of the traditional three-axis linkage machine tool, that is, the axes along the X, Y, and Z directions respectively, and each axis is equipped with a drive unit. , when printing, it moves freely with the transmission mechanism on the three axes. The...

Problems solved by technology

However, the support structure of this 3D printer is complex, and all positioning needs to be adjusted by the print head to control the X-axis, Y-axis, and Z-axis. As a result, some printing dead angles cannot be printed, and unnecessary collisions will occur, which will affect the quality of printing.
