Colored 3D printer nozzle avoiding color mixing

Abstract

The invention discloses a colored 3D printer nozzle avoiding color mixing. The colored 3D printer nozzle avoiding color mixing mainly comprises a supporting main body, a multi-nozzle component which is arranged on the supporting main body and can rotate around axis self and a power supply part; the multi-nozzle component also comprises diversion holes which have the amount being identical to an amount of nozzles and communicate with inner cavities of the nozzles in a one-to-one correspondence manner; a plane located by a connection line of the center of each diversion hole and the rotation center of the multi-nozzle component is a datum plane a; an angle of the multi-nozzle component each rotation is a multiple of an included angel between adjacent datum planes a; the discharge port of a molten flow channel is kept to be always communicated with the feeding port of one diversion hole; the supporting main body is also provided with an air duct; the air inlet port of the air duct is connected with a high-pressure air source; the exhaust port of the air duct can be sequentially communicated with the diversion holes in the switching process; and the power supply part comprises a powerreceiving element which is connected with the multi-nozzle component and is used for driving the multi-nozzle component to rotate and a power output element used for receiving a rotation force and transferring the force to the power receiving element.

Description

[0001] This invention is a divisional application of an invention patent with the application date of July 25, 2017, the application number: 201710609114X, and the invention title of "dragging type 3D printer nozzle for color mixing or color printing". technical field [0002] The invention relates to a 3D printer, in particular to a structure capable of clearing consumables accumulated in the inner chamber of a 3D printing nozzle, and is especially suitable for 3D color mixing / color printing. Background technique [0003] In recent years, 3D printing technology has developed rapidly. By combining with CNC machining, casting, metal cold spraying, silicone mold and other manufacturing methods, this technology has become an effective means of manufacturing modern models, molds and parts. Home appliances, biomedicine, cultural creativity and other fields have been applied to a certain extent, and it also occupies a unique position in application fields such as engineering and te...

Problems solved by technology

[0004] In the existing color mixing / color printing process, the printing method is still the traditional single-head structure, and the raw materials are fused with each other during the refueling process, resulting in a large color deviation of the printed object; in addition, when the 3D printer is in the shutdown state , the consumables accumulated in the nozzle gradually solidify as the temperature drops, and when the printing consumables are pulled out by mistake by external force, it is easy to cause damage to the parts in the nozzle
