Abstract

The invention relates to the technical field of printer nozzle heat dissipation, and particularly relates to a 3D printer nozzle heat dissipation device. The technical problem that an existing heat dissipation device mainly conducts heat dissipation through metal conduction and fan blowing heat dissipation pieces, and the overall heat dissipation effect is not good enough is solved. In order to solve the technical problem, the 3D printer nozzle heat dissipation device is composed of an annular airflow dispersion mechanism and a locking device. Airflow makes contact with the surface of a conveying pipe, direct heat dissipation is conducted through rapid surging of the airflow, and heat is prevented from being accumulated on the conveying pipe. The active heat dissipation airflow is sprayed out through jet holes, secondary heat dissipation is conducted on heat conduction ring pieces again through the airflow, and the heat dissipation effect of the heat conduction ring pieces is improved. When the jet holes annularly formed in the surfaces of the heat conduction ring pieces at equal intervals spray the airflow, reverse thrust can be formed relative to a nozzle through the airflow in all the radial directions, accordingly, vibration of the nozzle in the using process is balanced, and the printing precision of a printer is effectively improved.

Description

technical field [0001] The invention relates to the technical field of heat dissipation for a nozzle of a printer, in particular to a heat dissipation device for a nozzle of a 3D printer. Background technique [0002] Fused filament deposition modeling is currently the fastest-growing and most promising 3D printing rapid prototyping technology. The working principle of fused deposition modeling is that the hot-melt material, such as ABS, is first melted by the heater and drawn into a filament, and then the FDM molding equipment sends the filament-shaped printing material into the hot-melt nozzle through the wire feeding mechanism, and is drawn in the nozzle. Heating and melting, the nozzle moves along the section profile and filling trajectory of the part, extrudes the semi-fluid material according to the path controlled by the CAD layered data of the processed product, deposits it at the designated position, solidifies and forms, and bonds with the surrounding materials, la...
