Background technology
3D printer is also known as three-dimensional printer (3DP), is a kind of a kind of machine of accumulation manufacturing technology, i.e. RP technique
Device, based on it is a kind of digital model file, with special wax material, powdery metal or plastics etc. can jointing material, pass through
Printing jointing material from level to level manufactures the object of three-dimensional.Three-dimensional printer is used to manufacture product at this stage.Successively print
Mode carry out the technology of constructed object.The principle of 3D printer is that data and raw material are put into 3D printer, and machine can be according to
Program from level to level manufactures product.
Raw material is melted into liquid by 3D printer using high-temperature heating, solidify afterwards is extruded by printing nozzle, finally vertical
Body spatially arrangement form three-dimensional real object.3D printer nozzle of the prior art is generally all useful for the heating of heating raw material
Chamber, is the guarantee that raw material is smoothly extruded to the temperature control at nozzle.Different printing raw materials, heating chamber need the temperature kept
Scope is also different, and the temperature of only heating chamber is maintained at temperature of the raw material just at molten condition, and raw material just can be uniform
Ejection.If temperature is excessive, nozzle discharge hole it is possible that the phenomenon of " wire drawing ", and part top layer it is also possible to because
Temperature is excessive and deforms upon；If temperature is too low, the material moment solidification of nozzle is just ejected, has caused spray nozzle clogging.
Utility model content
The purpose of this utility model is that for existing 3D printer nozzle above shortcomings, there is provided a kind of band temperature
The 3D printer nozzle of control, according to the molten condition temperature of raw material, adjusts the temperature of heating chamber, raw material is uniformly sprayed
Go out.
To achieve the above object, the technical solution of the utility model is：A kind of 3D printer nozzle with temperature control, including
Nozzle, the heating chamber on nozzle and the heating rod in heating chamber, further include temperature conditioning unit, and the temperature conditioning unit includes
Temperature sensor in heating chamber, the controller arranged on nozzle exterior, the cooling tube and ring for being surrounded on nozzle outer surface
The resistance wire being around in heating chamber, the cooling tube connect cooling water pump, and the cooling water pump connects refrigerator；The resistance
Silk, the temperature sensor and the refrigerator are connected with the controller.
Preferably, the cooling tube spiral surrounding is in the nozzle outer surface.
Preferably, the resistance wire is helically wound around on the heating chamber side wall.
Preferably, the refrigerator is magnetic refrigerator, including permanent magnet, the turntable that is arranged between permanent magnet the two poles of the earth, edge
Cold working medium of the circle distribution on turntable, and it is arranged on the motor at center of turntable.
The beneficial effects of the utility model are：
The utility model is rational in infrastructure, and the temperature adjustment precision in heating chamber is high, and raw material sprays uniform.The utility model leads to
Excess temperature sensor measures the temperature in heating chamber in real time, according to the melting temperature of different materials, is adjusted and added by temperature conditioning unit
The temperature of hot intracavitary, makes the temperature of heating chamber be maintained at temperature of the raw material just at molten condition, raw material is uniformly sprayed
Go out, be not in wire drawing phenomenon or cause spray nozzle clogging.If it is excessive to heat cavity temperature, refrigerator work is controlled by controller
Make, nozzle is cooled down by cooling tube, reduce the temperature in heating chamber, if temperature is too low, resistance is controlled by controller
Silk auxiliary heating, improves the temperature in heating chamber.

Embodiment
In the following, the present invention is specifically described by exemplary embodiment.It should be appreciated, however, that not into one
In the case of step narration, element, structure and features in an embodiment can also be advantageously incorporated into other embodiment
In.
, it is necessary to explanation, the orientation or position of the instruction such as term " interior ", " outer ", " side " in the description of the utility model
It is based on position relationship shown in the drawings to put relation, is for only for ease of the description present invention and simplifies description, rather than instruction or
Imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore it is not intended that
Limitation to the utility model.
A kind of 3D printer nozzle with temperature control as shown in Figure 1 is understood, should include nozzle 1, adding on nozzle 1
Hot chamber 2 and the heating rod 3 in heating chamber 2, further include temperature conditioning unit, and the temperature conditioning unit includes being arranged in heating chamber 2
Temperature sensor 4, the controller 5 outside nozzle 1, the cooling tube 6 for being surrounded on 1 outer surface of nozzle and it is surrounded on heating
Resistance wire 7 in chamber 2, the cooling tube 6 connect cooling water pump 8, and the cooling water pump 8 connects refrigerator 9；The temperature
Sensor 4, resistance wire 7 and the refrigerator 9 are connected with the controller 5.6 spiral surrounding of cooling tube is in the nozzle
Outer surface.The resistance wire 7 is helically wound around on 2 side wall of heating chamber.
