Anti-deformation 3D printer nozzle

Abstract

The invention relates to the technical field of 3D printing, and discloses an anti-deformation 3D printer nozzle. The anti-deformation 3D printer nozzle comprises a positioning table; a displacement mechanism is installed on the positioning table; the positioning table is fixedly connected with the displacement mechanism; a pair of symmetrical wire supply wheels is installed in an inner cavity ofthe positioning table; a wire penetrates through the center of the positioning table; a limiting nozzle is fixedly connected to the center of the bottom end of the positioning table; and the top of the limiting nozzle is movably sleeved with a stabilizing frame. According to the anti-deformation 3D printer nozzle, by designing a water cooling pipeline and a compression ring, when the cooling efficiency of the water cooling pipeline becomes slow due to overheating of a heating block, gas in the compression ring is heated to expand to drive the water cooling pipeline to stretch synchronously, sothat the pipe diameter of the water cooling pipeline becomes large; the flow volume of the water cooling pipeline becomes large; the flow speed of the water cooling pipeline is reduced, thereby accelerating the cooling efficiency; the problem that energy consumption is increased due to the fact that the power of the water pump is increased is avoided; and meanwhile, vibration brought by a water pump is kept minimum, so that vibration borne by the 3D printing nozzle is minimum, and the problem that the printing precision of the 3D printing nozzle is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to an anti-deformation 3D printer nozzle. Background technique [0002] 3D printing technology refers to the technology of generating three-dimensional entities through continuous physical layer superposition and adding materials layer by layer. Generally, hot melt nozzles are used to squeeze and accumulate materials in a semi-fluid state according to the path controlled by CAD layered data. Solidify into a prototype at a designated position, extrude and accumulate layer by layer, and form the entire prototype or part after solidification. [0003] One of the important working components is the heating nozzle. Its working principle is to continuously send the silk material to the nozzle through the feeding wheel, and after being heated by the heating zone above the nozzle to form a molten state, the subsequent silk material acts as a piston to extrude it from the nozzle. , beca...
