AI Technical Summary

Technical Problem

After printing of the existing wax 3D printer, the wax cavity in the nozzle and the waste wax remaining at the nozzle can easily clog the nozzle, resulting in poor printing. The existing cleaning method requires manual operation, which can easily lead to scalding and inconvenient.

Method used

A fully automatic 3D printer nozzle cleaning system is designed, including cleaning components and collection components. The cleaning assembly scrapes the wax at the bottom of the nozzle into the waste pool through a scraper, and the entire cleaning process is automatically controlled by the control system. The collection component realizes fully automatic collection of waste wax through electrical heating and automatic collection functions.

Benefits of technology

It realizes efficient cleaning of the nozzle, avoids safety hazards and inconveniences in manual operation, and improves cleaning efficiency and safety.

Abstract

The present invention discloses a 3D printer nozzle cleaning system, which is installed on a 3D printer and includes a cleaning component for cleaning the nozzle, wherein the cleaning component includes a scraper for cleaning the nozzle and a waste pool for receiving waste cleaned from the nozzle, and the scraper is installed in the waste pool. The cleaning method is as follows: the cleaning component is moved to the bottom of the printing platform under the drive of the printing platform or through an autonomous motion mechanism, the printing nozzle squeezes the waste wax in the wax cavity through air, the scraper scrapes the waste at the bottom of the printing nozzle, the cleaning component moves to the bottom of the printing platform, new wax enters the wax cavity for printing and spraying, and the new wax is sprayed into the waste pool. The entire cleaning process is controlled by a control system, no manual operation is required, and the cleaning efficiency is high.
