Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Such as Figure 4-11 As shown, a 3D printing nozzle with material stirring and extrusion simultaneously and continuous spiral wire feeding, including: motor 100, cylinder 200, rotating drum 300, upper transmission shaft tube 400 and lower driving shaft arranged on the central axis of rotating drum 300 Shaft tube 500, uniform material device 600, spatula nozzle 700 and support frame 800;

[0039] The motor 100 is set on the support frame 800, the output shaft of the motor 100 is connected with the transmission gear set 401, and the transmission gear set 401 is fixedly connected with the upper transmission shaft tube 400, and the motor 100 drives the upper transmission shaft tube 400 counterclockwise through the transmission gear set 401 rotation; the upper transmission shaft tube 400 is fixedly connected with a planetary gear set 402, and the p...

Abstract

The invention discloses a 3D printing nozzle for continuous material stirring and extruding and continuous spiral wire feeding. The 3D printing nozzle comprises a motor, a cylinder, a rotating drum, an upper transmission shaft pipe, a lower transmission shaft pipe, a material equalizing device, a spatula nozzle and a supporting frame, wherein the upper transmission shaft pipe and the lower transmission shaft pipe are arranged on the central axis of the rotating drum. According to the 3D printing nozzle, dry powder enters a spray nozzle and is mixed with liquid to be extruded, so that the usageamount of retarder of traditional 3D concrete can be greatly reduced, and various performance indexes of the 3D concrete can be beneficially improved. Area requirements of a concrete 3D printing siteare reduced. Energy is saved, and the environment is protected. A liquid inlet port has strong flow and slow flow interfaces, and strong water flow can be used for flushing after use. Parts are modular components which are convenient to maintain and replace. An outlet spatula nozzle rotates clockwise to realize the function of smoothing the profile side wall and obtain a smooth lateral side. According to the 3D printing nozzle, a spirally wound steel wire (or long fiber wire) is internally arranged, so that the strength and toughness of 3D concrete materials is effectively enhanced, and the crack resistance of members is obviously improved.

Description

technical field [0001] The present invention relates to the field of 3D printing devices, and in particular provides a 3D printing nozzle for material stirring and extrusion at the same time and continuous spiral wire feeding, which is a kind of dry material entry, water mixing, stirring, extrusion, containing A device integrating continuous spiral steel wire (or continuous long fiber wire) and profile control. Background technique [0002] At present, the traditional concrete 3D printing uses the wet concrete material after mixing, which is pumped to the print head of the 3D printer through the pipeline through the pressure pump, and then is extruded through the extrusion device of the print head to realize the printing process. The form of adding steel wire in the concrete 3D printing process is a direct drag type, and the wire feeder uses the rigidity of the steel wire to input the steel wire in front of the printing process. For the traditional concrete 3D printing proc...
