Problems solved by technology

Existing FDM printing equipment generally adopts fan cooling, which has high noise and unstable cooling, which affects the printing effect
For example, the application number is 201420334367.2, and the name is "Integrated split flow heat dissipation print head for 3D printer". The print head is cooled by cooling fans, heat sinks, and flow guide grooves, but it is undeniable that the air cooling is unstable and noisy. However, FDM printing has extremely high requirements on temperature stability, and poor stability can easily cause nozzle clogging, wire drawing, adhesion, etc., and affect the effect of printed products.

Abstract

The invention provides a cooling device for a printing head of a 3D printing apparatus. The printing head comprises an extrusion screw machine barrel and a heater arranged on the extrusion screw machine barrel. The cooling device comprises cooling plates arranged around the heater, wherein cooling water channels for cooling water to pass by are formed inside each cooling plate. According to the cooling device for a printing head of a 3D printing apparatus, the cooling stability of the printing head is high, and the cooling noise of the printing head is low.

Description

technical field [0001] The invention relates to an auxiliary device for FDM printing equipment, which is mainly used in the technical field of cooling the printing head of the 3D printing equipment, in particular, relates to a cooling device for the printing head of the 3D printing equipment. Background technique [0002] Existing FDM 3D printing is in the form of melt extrusion. Due to the heating of the screw and the heat generated by the extrusion itself, it is necessary to cool the extrusion mechanism and avoid heat transfer to the transmission parts of the equipment. Existing FDM printing equipment is generally cooled by a fan, which is noisy and unstable in cooling, which affects the printing effect. For example, the application number is 201420334367.2, and the name is "Integrated split flow heat dissipation print head for 3D printer". The print head is cooled by cooling fans, heat sinks, and flow guide grooves, but it is undeniable that the air cooling is unstable an...
