A 3D printer automatic color changer

Abstract

The invention proposes an automatic color changing machine of a 3D printer. The color changing machine comprises a baseplate; a carrying device, a feeding mechanism and a servo module are arranged on the baseplate; the feeding mechanism is positioned between the carrying device and the servo module; the feeding mechanism includes multiple hobbing feeders linearly arranged; the carrying device includes multiple feeding discs corresponding to the hobbing feeders; the servo module is slidingly connected with a clamping block for conveying and cutting coloring materials; and the coloring materials on the feeding discs penetrate through the hobbing feeders and the clamping block in sequence. The color changing machine automatically changes colors in normal printing process, can enable single-color models to become more colorful, can satisfy specific functions of multi-color products, uses the slide rail type clamping devices to realize more stable conveying, uses the fixed feeding discs for achieving higher stability, automatically cuts off the coloring materials, prevents snapping of the coloring materials, and is excellent in use effect.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an automatic color changing machine for a 3D printer. Background technique [0002] At present, 3D printing technology is developing very rapidly. During the working process of 3D printers, the filament is heated to a molten state in the nozzle by electric heating. The nozzle discharges the filament according to a certain path, and the molten filament is bonded to the workbench. On top of that, every time a layer is processed, the workbench is lowered to the height of one layer, and the layer-by-layer deposition is repeated until a 3D model is printed. The main consumables for 3D printing are hot-melt materials. If you print models with multiple colors, you need to change the material many times. However, the existing 3D printers need to manually change the material, which is very troublesome. In addition, if the remaining material is not enough to support the entire model d...

Problems solved by technology

The main consumables for 3D printing are hot-melt materials. If you print a model with multiple colors, you need to change the material many times. However, the existing 3D printers need to manually change the material, which is very troublesome.

In addition, if the remaining material is not enough to support the entire model during the printing process, the printing will be interrupted in the middle, which will affect the continuity of the printing work. Usually, the operator needs to watch in real time and replace it in time when the remaining material is insufficient. The degree of automation is low and the increase reduce the workload of the operator;

[0003] The patent publication number is: CN 104228065 A invention patent discloses a 3D printer automatic refueling device, which uses a rotary feeding mechanism, so that the entire structure is not stable enough during feeding, and the color material will be broken when the rotation is unstable;

[0004] Another example is the invention patent with the patent announcement number: CN 103770334 B, which uses a color-changing mechanism, but it still uses a rotating method for refueling, and the structure of the gears is prone to jamming, and the use effect is poor
