Abstract
The present invention relates to a kind of 3D printer new type nozzle, its good heat dissipation, due to the characteristic of the non-sticky material of polytetrafluoroethylene (PTFE), make the consumptive material of melting downwards during extrusion almost without what resistance be subject to, the consumptive material for the melting so extruded is very uniform, thereby ensure that the precision of printing so that the surface of the workpiece printed is especially fine and smooth；Scheme is, including the heating unit being set with nozzle and nozzle, upper end of nozzle is fixed with the stainless steel tube being connected with the spray chamber in nozzle, stainless steel tube upper end is communicated with raw material guide pipe, and the stainless steel pipe coat is equipped with aluminium alloy heat dissipation head, it is characterised in that, radiating fin is disposed with aluminium alloy heat dissipation head, polyfluortetraethylene pipe is equipped with stainless steel guide pipe, polyfluortetraethylene pipe upper end connection raw material guide pipe, polyfluortetraethylene pipe lower end is placed in the spray chamber upper end of nozzle.
Description
Technical field
The present invention relates to 3D printer, especially a kind of 3D printer new type nozzle.
Background technology
In the case where 3D printing becomes a kind of overall situation of new processing technology, requirement of the people for printing precision is increasingly
It is high.The 3D printer for being currently based on FDM technology is quantitatively most, but most print quality is very general now,
Its reason has at 2 points：The fluency of mechanical precision and nozzle extrusion molten plastic silk.Mechanical precision mainly by design rationality and
The precision of parts machining, and solved the problem of nozzle aspect mainly by the reasonability innovation of design, traditional 3D printer
Stainless steel tube internal diameter in nozzle is 2 millimeters, and outside diameter is 6 millimeters, does not install polyfluortetraethylene pipe additional, extruder is in downward feeding
During the material that melts be easy to get lodged in inside stainless steel pipe and radiate bad after pipe, the workpiece surface of printing is very thick
Rough, this is all due to that the melting consumptive material one extruded times, caused by wire vent is uneven.
The content of the invention
For the above situation, to overcome the defect of the prior art, it is new that the purpose of the present invention is just to provide a kind of 3D printer
Type nozzle, its good heat dissipation, due to the characteristic of the non-sticky material of polytetrafluoroethylene (PTFE), makes the consumptive material of melting almost not have during extruding downwards
Have and what resistance be subject to, the consumptive material for the melting so extruded is very uniform, thereby ensures that the precision of printing so that print
Workpiece surface it is especially fine and smooth.
The technical scheme is that including the heating unit that is set with nozzle and nozzle, upper end of nozzle be fixed with
The stainless steel tube that spray chamber in nozzle is connected, stainless steel tube upper end are communicated with raw material guide pipe, the stainless steel pipe coat dress
There is aluminium alloy heat dissipation head, it is characterised in that radiating fin is disposed with aluminium alloy heat dissipation head, is equipped with stainless steel guide pipe poly-
Tetrafluoroethene pipe, polyfluortetraethylene pipe upper end connection raw material guide pipe, polyfluortetraethylene pipe lower end is placed in the spray chamber upper end of nozzle.
Good heat dissipation of the present invention, polytetrafluoroethylene (PTFE) characteristic are non-sticky material, make melting consumptive material downwards extrusion during almost
Any resistance be not subject to, the consumptive material for the melting so extruded is very uniform, ensure that the precision of printing so that print
Workpiece surface is especially fine and smooth comfortable.
Brief description of the drawings
Fig. 1 is front view of the present invention.
Fig. 2 is sectional view along A-A in Fig. 1.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with attached drawing.
As depicted in figs. 1 and 2, the present invention includes the heating unit 2 being set with nozzle 1 and nozzle 1, and 1 upper end of nozzle is consolidated
Surely there is the stainless steel tube 3 being connected with the spray chamber in nozzle 1,3 upper end of stainless steel tube is communicated with raw material guide pipe 4, described stainless
Aluminium alloy heat dissipation head 5 is set with outside steel pipe 3, it is characterised in that 5 periphery of aluminium alloy heat dissipation head is disposed with radiating fin 501, stainless
Polyfluortetraethylene pipe 6,6 upper end of polyfluortetraethylene pipe connection raw material guide pipe 4,6 lower end of polyfluortetraethylene pipe are equipped with steel pipe 3
It is placed in the spray chamber upper end of nozzle 1.
The stainless steel tube 3 is 304 stainless steel tubes.
The internal diameter of the stainless steel tube 3 is 4 millimeters, and outside diameter is 6 centimetres, and 6 internal diameter of polyfluortetraethylene pipe is 2 millimeters,
Outside diameter is 4 millimeters, and such polyfluortetraethylene pipe 6 is just injected inside stainless steel tube 3, at the brass nozzle 1 that goes directly, 304 stainless steels
Material good heat dissipation, along with wall thickness is very thin, is conducive to radiate, and polytetrafluoroethylene (PTFE) characteristic is non-sticky material, makes the consumptive material of melting downward
Almost without what resistance be subject to during extrusion, the consumptive material for the melting so extruded is very uniform, thereby ensures that printing
Precision so that the workpiece surface printed is especially fine and smooth comfortable.
