The beneficial effects of the utility model are that the inside of thermostatic chamber sets up agitating unit, and with the consumptive material stirring, the heat preservation that sets up on the inner wall reduces calorific loss, and the closing control consumptive material of control solenoid door is extruded by the nozzle ration, and the inner wall of the inside nozzle bushing pipe that sets up of nozzle is smooth, reduces the condition that the shower nozzle blockked up, and the heating ring twines on the guide passageway for the heating degree is even, avoids appearing the superheating or does not heat complete phenomenon.
Description
Technical field
This utility model belongs to 3D printing device technical field, especially relates to the spray of a kind of 3D printer
Head unit.
Background technology
3D printer carries out print job after printing silk material is melted extrusion.Silk material is by feeding trunnion
Enter shower nozzle heated device heating and melting.Feeding trunnion generally selects the stainless steel that thermal conductivity is slower
Expecting, shower nozzle then selects the pyrite that heat conduction rate is fast, and therefore the melting process of solid-state silk material is in the showerhead
Carry out.The structure design of printing head can directly affect the print quality of 3D printer.Due to heating
There is heat conduction in position, easily causes silk material and start tube expansion in rustless steel through hole compunction, and due to stainless
The through hole cavity of steel matter, deformation coefficient is little, and inner wall roughness is big, easily causes silk material to lead at rustless steel
Blocking in the cavity in hole.The design of this shower nozzle can not use the consumptive material of the materials such as PLA, and the materials such as PLA
Matter is printed material the most conventional in 3D prints, and seriously limits the material selection range that 3D prints,
Affect the use that 3D prints.
In print procedure can occurrence temperature wave phenomenon, some are to the strict printed material of temperature requirement, its
Temperature fluctuation exceeds its melting range, it may appear that print fault or discharging are uneven, affect model surface
The various problems such as flatness, affect being normally carried out of 3D printing.
Utility model content
The purpose of this utility model be to provide a kind of simple in construction, simple to operate, be not easily blocked, there is perseverance
The ejecting device of the 3D printer that temp effect, production efficiency are high.
The technical solution of the utility model is: the ejecting device of a kind of 3D printer, including head body,
Guide passage, heater, be provided with guide passage inside described head body, described heater is arranged on leads
The outside of the passage of heat, described heater includes heating ring, heat-conducting layer, and described heating ring is looped around guide and leads to
On road, the inside of described head body is provided with thermostatic chamber, and the inwall of described thermostatic chamber is provided with heat-insulation layer, institute
The center stating thermostatic chamber is provided with agitating device, and described thermostatic chamber connects with nozzle, and described nozzle is with permanent
Greenhouse contact position is provided with electromagnetic valve, and the inside of described nozzle is provided with nozzle bushing pipe.
Further, the internal diameter of described nozzle bushing pipe is less than the internal diameter of nozzle.
Further, described nozzle bushing pipe uses exotic material.
This utility model has the advantage that with good effect: owing to using technique scheme, thermostatic chamber
Inside agitating device is set, consumptive material is stirred, on inwall arrange heat-insulation layer reduce thermal loss,
The Guan Bi controlling electromagnetic valve controls consumptive material by nozzle squeezing out quantitative, the nozzle bushing pipe that the inside of nozzle is arranged
Inner wall smooth, reduce shower nozzle blocking situation, heating ring be wrapped on guide passage so that heating journey
Degree is uniformly, it is to avoid superheated occurs or does not heats phenomenon completely, more convenient to use；Have
Simple in construction, good constant-temperature effect, processing cost is low, production efficiency advantages of higher.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is elaborated.
As it is shown in figure 1, the ejecting device of this utility model a kind of 3D printer, including head body 1,
Guide passage 2, heater 3, described head body 1 is internal is provided with guide passage 2, described heater 3
Be arranged on the outside of passage of heat 2, described heater 3 include heat ring 4, heat-conducting layer 5, described in add
Hot ring 4 is looped around on guide passage 2, and the inside of described head body 1 is provided with thermostatic chamber 6, described perseverance
The inwall in greenhouse 6 is provided with heat-insulation layer 7, and the center of described thermostatic chamber 6 is provided with agitating device 8, institute
Stating thermostatic chamber 6 to connect with nozzle 9, described nozzle 9 is provided with electromagnetic valve 10 with thermostatic chamber 6 contact position,
The inside of described nozzle 9 is provided with nozzle bushing pipe 11.
The internal diameter of described nozzle bushing pipe 11 is less than the internal diameter of nozzle 9.
Described nozzle bushing pipe 11 uses exotic material.
The work process of this example: the inside of thermostatic chamber 6 arranges agitating device 8, is stirred by consumptive material,
The heat-insulation layer 7 arranged on the inwall of thermostatic chamber 6 reduces thermal loss, controls the Guan Bi of electromagnetic valve 10
Control consumptive material by nozzle 9 squeezing out quantitative, the inner wall smooth of the nozzle bushing pipe 11 that the inside of nozzle 9 is arranged,
Reducing the situation of shower nozzle 9 blocking, heating ring 4 is wrapped on guide passage 2 so that degree of heat is uniform,
Avoid the occurrence of superheated or do not heat phenomenon completely；Outer 2 outer layers of conduction copper include that heat-conducting layer 5 plays
Certain thermolysis, it is to avoid cause the material of passage of heat 2 to occur expanding due to too high temperature,
Cause the blocking within head body 1, affect the normal use of 3D printer.
Above an embodiment of the present utility model is described in detail, but described content has been only this reality
