Embodiment 1

[0040] The processing equipment for 3D printing wire includes a barrel and an extruder located directly below the barrel. A main feeding device 30A and a plurality of auxiliary material feeding devices are arranged at the mouth of the barrel. The main feeding device 30A The small screw and the screw of the extruder maintain a certain speed ratio and continue to run; there are five auxiliary material feeding devices above the extruder, which are the first auxiliary material feeding device C01, the second auxiliary material feeding device C02, The third auxiliary material feeding device C03, the fourth auxiliary material feeding device C04 and the fifth auxiliary material feeding device C05. Specifically, add additives to polylactic acid raw materials and mix them into barrel B, use 10 grams of toners in five colors of red, green, yellow, blue, and orange, and mix them with 800 grams of polylactic acid raw materials evenly, and the diluted The toner is respectively put into the ...

Embodiment 2

[0042] control image 3 : Mix the dried polylactic acid raw materials and additives into the barrel, use 10 grams of red, green and yellow toners, mix and dilute the toners with 800 grams of dried polylactic acid raw materials, and then put in auxiliary materials in turn In the barrel of the feeding device, adjust the frequency converters of the extruder and the main feeding device to 23 and 2.3HZ respectively, the machine rotates, and the diluted toner is added as red-yellow-green-yellow-red, which is defined as C1-C3-C2-C3-C1, each adjacent two starts to rotate and feed at intervals of 10 seconds, and the next one rotates to feed when the previous one stops, and the red-yellow-green three colors can be extruded from the single-screw extruder Block gradient 3D printing filament. Among them, C1 in the figure represents the auxiliary material feeding device with red toner added, and so on for C2 and C3.

Abstract

The invention discloses a processing technology and processing equipment of a 3D printing wire. An underfeeding way is adopted to feed materials, wherein the underfeeding way is achieved by regulating the screw speed of granules falling into an extruder before feeding materials by virtue of a small-screw feeding device, and the feeding speed of the small-screw feeding device and the rotating speed of the screw of the extruder are kept at a certain speed ratio so as to achieve continuous running; raw materials are added from the blanking hole of a main extruder by regulating the ratio of the inflow velocity of main materials to the adding speed of different auxiliary materials, and discontinuous multi-color extrusion is achieved according to the ratio of the adding time ato the rotating speed of the different auxiliary materials. The processing equipment comprises a charging barrel and an extruder below the charging barrel. By virtue of the technology, a problem that the screw of the extruder is locked during extruding can be avoided, and a colorful 3D printer wire can be produced.

Description

technical field [0001] The invention relates to the technical field of three-dimensional printing, in particular to a processing technology suitable for 3D printer consumables made of polylactic acid materials. [0002] Another aspect of the present invention relates to processing equipment for preparing 3D printer wires from polylactic acid materials. Background technique [0003] A 3D printer, also known as a three-dimensional printer, is a machine that uses rapid prototyping technology. Based on digital model files, it uses molding materials to construct three-dimensional entities by layer-by-layer printing. Before printing, it is necessary to use computer modeling software to model, and then "partition" the built 3D model into layer-by-layer sections, that is, slices, so as to guide the 3D printer to print layer by layer. 3D printers have been widely used in the product manufacturing industry. The working principle of 3D printers is basically the same as that of traditi...
