Description
Technical field
The utility model belongs to printing equipment technical field, more particularly, to a kind of 3D printer printhead cooling mechanism.
Background technology
The 3D printer difference maximum with conventional printer is that " ink " that it is used is raw material true.This
Melted after a little raw material are heated, be cooled to solid-state after being sprayed from the printhead shower nozzle of 3D printer, the process entirely printed
It is exactly that shower nozzle constantly sprays the raw material of liquid according to program and successfully cooled down on model, finally gives generally only using for 3D
Fan structure carries out the solid material object that cools.But the effect of heat insulation between existing 3D printer fire end and radiating end is poor, this
Sample just causes two problems：1st, the heat of fire end is delivered in radiating end rapidly, causes fire end heat to scatter and disappear larger, energy consumption
It is higher；2nd, the temperature in radiating end is higher, and consumptive material softens too early in radiating end, causes that the wire vent efficiency of shower nozzle is low, shower nozzle
Easily block, consumptive material extrusion difficulty.
The content of the invention
Problem to be solved in the utility model is to provide a kind of 3D printer printhead cooling mechanism.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of 3D printer printhead radiating
