Improved lifting mechanism for 3D printer

Abstract

The invention provides an improved lifting mechanism for a 3D printer. The improved lifting mechanism solves the problem of the poor lifting effect of a lifting mechanism in the prior art. The improved lifting mechanism for the 3D printer comprises a base. Multiple mounting holes are formed in the base. An upright post is fixedly arranged in each mounting hole. A printing nozzle for printing is arranged between every two upright posts. Lifting mechanisms capable of controlling rising or falling of the printing nozzles are arranged between the printing nozzles and the upright posts. Each lifting mechanism comprises three lifting rails fixed on the three upright posts, three lifting blocks are arranged on the three lifting rails in a matched manner, each lifting block is sleeved with four pulleys, the pulleys are matched with the lifting rails, each lifting block is further provided with two outward protruding parts, a first hinged hole is formed in each protruding part, each lifting block is hinged to the upper end of a control arm through a first hinge column, the lower end of each control arm is connected to the corresponding printing nozzle, and a telescopic rod with a telescopicfunction is arranged in the middle part of each control arm. The improved lifting mechanism for the 3D printer has the beneficial effect of being good in lifting effect.

Description

technical field [0001] The invention belongs to the technical field of 3D printing and relates to an improved 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 a...

AI Technical Summary

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.
