Abstract

The invention discloses an adjustable nozzle for a 3D printer, comprising a moving block; a horizontal guide rail is slidably nested in the moving block through a slider; each of the front and rear ofthe horizontal guide rail is provided with a slide groove matching with the slider; a first rack is fixedly connected to the upper surface of the horizontal guide rail; a second rack is fixedly connected to the lower surface of the horizontal guide rail; each of the upper and lower surfaces of the horizontal guide rail is provided with a rectangular through hole; a melting mechanism is fixedly connected to the front of the moving block and includes a first barrel, a heating element is fixed to the inner wall of the first barrel, a circular plate is fixedly connected to the upper surface of the first barrel, and the upper surface of the circular plate is provided with two through holes. The adjustable nozzle is convenient to operate, and can be adaptively adjusted according to the shape orsize of a target model, so that printing efficiency is improved, printing time is shortened, the quality of 3D printed products is improved, product yield is increased, and long-term development of enterprises is benefited.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to an adjustable nozzle for a 3D printer. Background technique [0002] Fused filament deposition modeling is currently the most rapidly developing and most promising 3D printing rapid prototyping technology. The wire mechanism feeds the filamentary printing material into the hot melt nozzle, where it is heated and melted, and the nozzle moves along the cross-sectional contour of the part and the filling trajectory, extruding and depositing the semi-fluid material according to the path controlled by the CAD layered data of the processed product It is solidified and formed at the designated position, and bonded with the surrounding materials, forming layers of layers. [0003] Existing 3D printers use a single nozzle to print the target model. The shape and size of various target models are different. Because the cross-sectional shape of the single nozzle is fixed, it cannot be ...
