AI Technical Summary

Technical Problem

The installation errors of existing 3D printers and automatic feeding devices make it difficult to form an absolute level for the blade and the forming table, causing the model parts to be damaged and the yield is reduced.

Method used

A blade module is designed. The blade main body is assembled on the assembly base through elastic movement to form elastic movement, make up for installation errors, and the elastic movement of the blade main body is realized through the blade adapter platform and the elastic connection area.

Benefits of technology

Through the elastic assembly of the blade module, the installation error can be effectively compensated, ensuring the level of the blade and the forming table is consistent, avoiding the model parts being damaged, and improving the printing yield.

Abstract

The invention provides a scraper knife module, an automatic discharging device and a 3D printing system, and relates to the technical field of 3D printing, a scraper knife assembly comprises an assembly seat body and a scraper knife main body, the assembly seat body is movably assembled on a module platform along a scraper knife movement track, and the scraper knife movement track is configured to be a linear track; the component seat body is configured to reciprocate relative to the module platform along the scraper knife movement track, and the scraper knife main body is elastically and movably assembled on the component seat body. On the basis of the elastic assembly state of the scraper knife body, the forming surface of the forming table can be tightly attached to the scraper knife body at the moment, and in the state, when the scraper knife body continues to move towards the forming table in the X-axis direction, the scraper knife body can be tightly attached to the forming surface of the forming table to shovel down the model part from the forming surface of the forming table; and the separation of the model parts is realized. In the process, the scraper knife body can only be attached to the top of the model piece to shovel the model piece down from the forming surface, and therefore the model piece cannot be damaged.
