Printing head device applied to large industrial FDM3D printer

Abstract

The invention relates to a printing head device applied to a large industrial FDM3D printer. The printing head device comprises a printing head nozzle, cooling plates, a heating sleeve, a shield, a printing head body, a double-head long shaft, a screw and clamping plates. The screw is assembled inside the heating sleeve, and one end of the screw is connected with a motor through the double-head long shaft; the heating sleeve is fixedly clamped through the clamping plates, and the printing head body is fixedly arranged at one end, away from the double-head long shaft, of the heating sleeve; the printing head nozzle is formed in the printing head body; clamping plate tightening threaded holes are formed in the side faces of each clamping plate, and the clamping plates are perpendicularly and fixedly arranged in the cooling plates through the clamping plate tightening threaded holes; and the shield is arranged at the position between one ends, away from the double-head long shaft, of the cooling plates and one end, away from the printing head nozzle, of the printing head body. The printing head device has the beneficial effects that the application field of the FDM3D printer is expanded; and seal reliability is improved, rapidness of temperature transfer is reinforced, the printing nozzle is conveniently exchanged, and printing nozzles of different types can be selected allowably.

Description

technical field [0001] The invention relates to a print head device of a 3D printer, in particular to a print head device applied to a large-scale industrial-grade FDM 3D printer, which belongs to the field of mechanical automation printing. Background technique [0002] The print head is a very important device in FDM 3D printing equipment. Its quality determines the quality of printing a three-dimensional solid model. Now small printers are very popular in the market. Their printing principle is mainly to print raw materials through a feeder. It is sent to the forming vessel device, and the printing raw material is brought into a molten state by heating the forming vessel, and then the molten printing raw material is transported to the printing head device through the cooperation of the main and driven rollers, and finally extruded through the printing head and stacked on the FDM 3D printer. On the printing platform, the desired three-dimensional solid shape is formed. Ho...
