A 3D printer nozzle anti-blocking structure

Abstract

The invention discloses an anti-blocking structure for a nozzle of a 3D printer in the technical field of 3D printers. The connection block is fixedly connected with the feed pipe, and a filter plate is arranged between the feed pipe and the nozzle. The filter plate is provided with a number of filter holes distributed in a circular array, and the filter plate is slidably connected to the feed pipe. The bottom of the feed pipe, the side wall of the filter plate is fixedly connected with a gas spring for its reset, the top of the feed pipe is rotatably connected with a first rotating shaft, and the first rotating shaft is slidably connected in the up and down direction with a The sliding sleeve inside the feeding pipe, the side wall of the sliding sleeve is rotatably connected with a rolling roller; it can greatly reduce the possibility of nozzle blockage, and can greatly increase the service life of the nozzle.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an anti-blocking structure of a 3D printer nozzle. Background technique [0002] 3D printers print by melting and extruding the printing silk. The wire material enters the head through the feeding throat and is heated and melted by the heating device. The feed throat is usually made of stainless steel with slow thermal conductivity, while the nozzle is made of brass with fast thermal conductivity, so the melting process of the solid wire material is carried out in the nozzle. [0003] During the melting process of the solid silk material in the prior art, some larger granular silk materials cannot be melted in time, and will be blocked in the nozzle to prevent the melted silk material from being ejected. Once the nozzle is blocked, 3D printing cannot continue. The staff needs to clean the nozzle before printing can continue, which will greatly increase the printing time. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-blocking structure for the nozzles of 3D printers, to solve the problem that some larger granular silk materials cannot be melted in time during the melting process of the prior art solid silk materials proposed in the background technology, and will be blocked in the The jetting of the melted filament is hindered in the nozzle. Once the nozzle is blocked, 3D printing cannot continue. The staff needs to clean the nozzle before continuing to print, which will greatly increase the printing time.
