Colour printer used for multicolor raw material differential velocity feeding

Abstract

The invention discloses a colour printer used for multicolor raw material differential velocity feeding. The colour printer used for multicolor raw material differential velocity feeding comprises a passive feeding mechanism; the passive feeding mechanism comprises a feeding power mechanism; the lower end part of the feeding power mechanism is connected with an extrusion mechanism; the cross colortype colour 3D printer extrusion mechanism comprises a support main body, and a rotary pedestal main body which is arranged on the lower bottom surface of the support main body, and is capable of rotating around the self axis; the support main body is provided with a plurality of molten channels capable of receiving molten state raw materials or generating molten state raw materials; material inlet ends of the molten channels are distributed on the upper top surface of the support main body; material outlet ends of the molten channels are distributed on the lower bottom surface of the supportmain body; the number of the molten channels is designed to be N, and the number of extrusion heads is designed to be N+1; N of the N+1 extrusion heads are communicated with the material outlet endsof the molten channels in vertical states in a corresponding manner; and one of the N+1 extrusion head is communicated with the material outlet ends of the molten channels in a vertical state, and color mixing is realized in the extrusion head.

Description

[0001] This invention is a divisional application for an invention patent with the application date of August 28, 2017, the application number: 2017107470637, and the invention title of "Passive Differential Feeding System for Cross-color Color 3D Printer". technical field [0002] The invention relates to a 3D printer, in particular to a 3D printer capable of actively cross-coloring. Background technique [0003] 3D printing has brought about a global manufacturing revolution. In the past, component design was completely dependent on whether the production process could be realized. The emergence of 3D printers will subvert this production idea, which makes enterprises no longer consider production when producing components. Process issues, the design of any complex shape can be realized by 3D printer; 3D printing can directly generate objects of any shape from computer graphics data without machining or molds, thus greatly shortening the production cycle of products and imp...

AI Technical Summary

Problems solved by technology

[0004] Existing 3D printers mostly use monochrome for printing, and color printers mostly use mixed-color raw materials for printing, that is, mixed-color materials produced by mixing raw materials of various colors; currently, 3D printers on the market do not use cross-color raw materials for printing , the cross-color raw material is made of multiple sections of different-color raw materials connected in series. Since different printing objects require different cross-color lengths and color distribution schemes, it is impossible to make cross-color raw materials before printing. Therefore, constraints The realization of cross-color printing
