The invention discloses a 3D printing spray head used in the construction field. Including upper shell, power drive mechanism, swash plate, swash plate spring, round table, rotary plate, plunger, sliding shoe, cylinder block, inner spring, rotary gasket, diverter plate, deflector plate, lower cylinder body, shaft and inclined Plate angle adjustment device; one end of the plunger is set in the channel of the cylinder body, and the other end is a circular joint matched with the sliding shoe; one end of the swash plate is an extension end, and the upper surface of the extension end is connected to the upper shell through a swash plate spring. The lower surface of the extended end of the swash plate is provided with an angle adjustment device; the inner spring bears against the cylinder body, thereby resisting the return plate through the round table, so that the sliding shoe placed on the return plate is close to the swash plate, and the cylinder body is controlled by the angle of the swash plate Pump the quick setting dose. The device can realize the functions of fully stirring the concrete slurry and the liquid quick-setting agent, mixing and uniformly extruding. And it can control the amount of liquid quick-setting agent and the control of the remaining material when printing stops.
Description
technical field [0001] The invention belongs to the field of 3D printing, in particular to a 3D printing nozzle used in the field of construction. Background technique [0002] 3D printing is a kind of rapid prototyping technology, which is a technology that constructs objects by layer-by-layer printing based on digital model files, using adhesive materials such as powdered metal or plastic. [0003] The working principle of 3D printing is basically the same as that of ordinary printers, but the printing materials are different. 3D printers are equipped with different "printing materials" such as metal, ceramics, plastics, sand, etc., which are real raw materials. After the printer is connected to the computer, it is controlled by the computer. The "printed materials" can be layered on top of each other, eventually turning the blueprints on the computer into real objects. A 3D printer is a device that "prints" real 3D objects. Many different technologies exist for 3D print...
