3D printer nozzle heat sink

Abstract

The invention discloses a 3D printer nozzle heat sink. The heat sink comprises a fixed table (1), a supporting plate (2), a buffer block (3) and a cooling fan (5); a nozzle (6) of a 3D printer is vertically fixed to the lower surface of the fixed table (1), the supporting plate (2) is arranged on the lower surface of the fixed table (1), and can slide in the direction close to and away from the nozzle (6), one end of the buffer block (3) is fixed to the surface, facing the nozzle (6), of the fixed plate (2), the other end of the buffer block (3) is detachably connected to the cooling fan (5), and an air outlet of the cooling fan (5) faces the nozzle (6). The 3D printer nozzle heat sink overcomes the defect that in the prior art, a cooling fan is fixed to the position beside a nozzle for carrying out heat dissipation on the nozzle, however, in the printing process, vibration generated during running of the cooling fan seriously affects the molding quality of a 3D printer.

Description

technical field [0001] The present invention relates to the field of 3D printers, in particular to a cooling device for nozzles of 3D printers. Background technique [0002] As one of the core components of the 3D printer, the nozzle of the 3D printer largely determines the quality of the molding. The smoothness of the filament flowing out of the extrusion nozzle and the temperature of the filament directly affect the accuracy of 3D printing. However, if the temperature of the nozzle is too high, other components will be dissolved and burned, so a heat dissipation device is required to control the temperature of the nozzle within a certain range. At present, a cooling fan is usually installed at the nozzle to dissipate heat from the nozzle, but in the prior art, a cooling fan is directly fixed next to the nozzle, but during the printing process, the vibration generated by the operation of the cooling fan will seriously affect 3D printer molding quality. [0003] Therefore...

Problems solved by technology

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problem in the prior art that a heat dissipation fan is directly fixed next to the nozzle to dissipate heat from the nozzle, but during the printing process, the vibration generated by the operation of the heat dissipation fan will seriously affect the 3D printing. The problem of the molding quality of the printer, so as to provide a 3D printer that can effectively dissipate heat from the printing nozzle during use, so that the temperature of the nozzle can be controlled within a certain range, protect the printer components, and will not affect the molding quality of the 3D printer.
