Abstract

The invention relates to a printing head for a 3D printer. The printing head comprises a printing base, a conveying mechanism and a printing mechanism, wherein the conveying mechanism is arranged on the printing base and used for conveying materials, and the printing mechanism is arranged on the printing base and used for melting and printing the materials. The printing seat comprises a base, a mounting top frame arranged on one side of the base and a mounting seat arranged on the mounting top frame, the mounting top frame is provided with a feeding guide seat which is located above the conveying mechanism and allows materials to pass through, and the mounting seat is provided with a mounting cavity; the conveying mechanism comprises a driving roller rotationally connected to the mounting base, a driven roller rotationally connected to the mounting base and a driving assembly for driving the driving roller and the driven roller to rotate so as to convey materials, and the driving roller and the driven roller are each provided with a liquid flowing channel for cooling liquid to pass through; and the printing seat is provided with a liquid conveying assembly for conveying cooling liquid to the liquid channel. The printing head has the effect of improving the heat dissipation effect of the printing head.

Description

technical field [0001] The present application relates to the technical field of 3D printing, in particular to a printing head for a 3D printer. Background technique [0002] Currently commonly used FDM (Fused Deposition Modeling) 3D printers use fused deposition manufacturing technology, using thermoplastic materials such as ABS and nylon, and using strip-shaped thermoplastic materials for feeding. The print head is provided with a nozzle for heating and melting the material, and a pair of delivery rollers that are rotatably connected to the print head and located above the nozzle to deliver the material to the nozzle. There is a gap between the two delivery rollers for the material to pass through and abut against the material. The nozzle moves along the section profile of the part and the filling track, and at the same time extrudes the molten material. The material solidifies rapidly and coagulates with the surrounding materials to form the required structure. [0003] ...
