Abstract
The present invention provides 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 melting consumptive material downwards extrusion during almost not by what resistance, 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 heater 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 a kind of 3D printer new type nozzle.
Background technology
In the case where 3D printing turns into a kind of overall situation of new process 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 shower nozzle extrusion molten plastic silk.Mechanical precision mainly by design rationality and
The precision of parts machining, and reasonability the problem of shower nozzle aspect mainly by design is innovated to solve, traditional 3D printer
Stainless steel tube internal diameter in shower nozzle is 2 millimeters, and external 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 prior art, it is new that the purpose of the present invention is just to provide a kind of 3D printer
Type shower nozzle, its good heat dissipation, due to the characteristic of the non-sticky material of polytetrafluoroethylene (PTFE), the consumptive material of melting is set almost not have during extruding downwards
There is the consumptive material for the melting by what resistance, so extruded very uniform, thereby ensure that the precision of printing so that print
Workpiece surface it is especially fine and smooth.
The technical scheme is that including the heater 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
Not by what resistance, 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 be in Fig. 1 A-A to sectional view.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the present invention includes the heater 2 being set with nozzle 1 and nozzle 1, and the upper end of nozzle 1 is consolidated
Surely there is the stainless steel tube 3 being connected with the spray chamber in nozzle 1, the upper end of stainless steel tube 3 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 the periphery of aluminium alloy heat dissipation head 5 is disposed with radiating fin 501, stainless
Polyfluortetraethylene pipe 6, the upper end of polyfluortetraethylene pipe 6 connection raw material guide pipe 4, the lower end of polyfluortetraethylene pipe 6 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 external diameter is 6 centimetres, and the internal diameter of polyfluortetraethylene pipe 6 is 2 millimeters,
External 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, be advantageous to radiate, polytetrafluoroethylene (PTFE) characteristic is non-sticky material, makes the consumptive material of melting downward
Almost not by what resistance 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.
