Automatic silk material replacing device for 3D printer and 3D printer with same

Abstract

The invention provides an automatic silk material replacing device for a 3D printer. The automatic silk material replacing device for the 3D printer comprises a printing box, an article carrying table and a printing device, the printing device comprises a lower box and an upper box which are fixedly connected with each other, a lower cavity is formed in the lower box, a belt gear is rotatably arranged in the lower cavity, compression boxes are symmetrically and fixedly arranged in the lower cavity, a feeding hole and a telescopic hole are formed in the inner cavity wall of each compression box, insertion holes corresponding to the telescopic holes are formed in the bottom wall of the lower box, heating blocks are fixedly arranged in the feeding holes, the heating blocks incompletely block the feeding holes, and feeding pipes are fixedly connected to the outsides of the feeding holes. According to the automatic silk material replacing device for the 3D printer, in the using process, silk materials can be automatically replaced by simply controlling the belt gear to rotate, it is guaranteed that the fused silk materials cannot drop on the article carrying table to cause pollution, the situation that the silk materials are replaced after being completely consumed can be known in time, the situation that a machine is damaged due to empty material running is avoided, the service life is prolonged, the time for replacing the silk materials by people is greatly saved, and the device is very worthy of popularization and use.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an automatic filament replacement device for a 3D printer and a 3D printer thereof. Background technique [0002] 3D printing, based on digital model files, uses powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. For color 3D printing, the current technology based on fused deposition modeling (FDM) 3D printing generally achieves color printing through manual refueling, and cannot automatically replace different colors of filaments, which leads to the need for personnel to keep an eye on refueling during the color printing process, resulting in low work efficiency. [0003] Publication number CN204997998U discloses a multi-head 3D printer that can automatically replace the print head. When working, the lifting mechanism drives the clamping seat to move, so that the clamping seat is sleeved on the lower end of the print head ...

[0004] However, during the use of the above-mentioned print head, there are still the following obvious defects: 1. The structure uses magnets to cooperate with the metal jacket to achieve adsorption, resulting in the need to overcome the magnetic attraction when separating, resulting in instability, resulting in structural compatibility of the print head Not good; 2. The print head is a single job, lacks colorful filaments, and cannot print in color; 3. When the filaments need to be replaced with other colors during the use of the filaments, the internal molten filaments will drop on the stage when the nozzles move Defects on printed objects
