With the development of electronic computer and automatic control technology, 3d printer has been used for the printing shaping of complex partses
Through being employed in a large number, the ultimate principle of 3d printer is that the raw material for shaped object is melted by feed mechanism feeding 3d printer
After the heated thawing in hot melt chamber in material body, the movement with printing nozzle is piled up after cooling once through printer nozzle extrusion
Formed exempt to process be formed object, be formed the mobile accuracy of the surface quality of object and dimensional accuracy and printing nozzle, former
Between the material printing nozzle raw material rate of outflow and discharge, there is strict corresponding relation, and the rate of outflow of raw material and discharge
Control relevant with its hot melting temperature, especially when extruded velocity adjusts, if temperature is too high when extrusion capacity reduces, due to
Cavity pressure is delayed, and hot melt can be led to continue to flow out, rather than timely minimizing, so may result in printed matter surface sediment and increases
Thickness, it is achieved that the fast temperature in the hot melt chamber in 3d printer melt body controls, is the surface matter improving in shaped object
Amount and the key of dimensional accuracy.Particularly temporarily only print or start moment, printing corner and the roundabout position printing, print procedure
Central Plains expects the rapidly minimizing of the rate of outflow, discharge it is desirable to hot melt chamber rapid cooling.The shower nozzle being rapidly heated and lowering the temperature can be big
Amplitude improves print speed and precision.
In prior art, the heating in 3d printer melt body is realized by electric heater, in 3d printer melt body
Radiating realized by the air-cooled such as or natural heat dissipation of setting outside 3d printer melt body, because air-cooled or natural cooling need
Realize the cooling in hot melt chamber after conduction, cause rate of cooling slow it is impossible to meet surface quality and the size essence of shaped object
The requirement of degree.
Content of the invention
It is to improve the surface quality of shaped object and the requirement of dimensional accuracy by adjusting melt extrusion temperature, the present invention is public
Open and a kind of the 3d printer melt extrusion mechanism of fast regulating temperature can realize the quick heating in 3d printer hot melt chamber and fast prompt drop
Temperature.
The present invention realize goal of the invention the technical scheme is that a kind of can fast regulating temperature 3d printer melt extruder
Structure, comprising: feed mechanism, melt body and printer nozzle, is provided with printing hot melt chamber and heater, beats in melt body
