3D printer is also known as three-dimensional printer, is a kind of cumulative manufacturing technology, i.e. a kind of machine of rapid shaping technique, it
It is, with adhesive materials such as special wax material, powdery metal or plastics, to pass through printing one based on a kind of mathematical model file
Jointing material layer by layer manufactures three-dimensional object.Liquid will be formed after material molten when 3D printing product finally to carry out heap and finish building
At printing, the material under each molten condition all becomes nematic liquid, due to the variation of nozzle and external temperature, these meltings
Silk thread carry out bonding eventually become one.
The mode of heating used in 3D printing equipment on current market is commonly resistance wire fever, by contacting conduction side
Formula passes to heat on trunnion wall, but only abuts against the heat on the inside of trunnion wall surface and just can preferably pass to heated object
On, the heat in outside is largely lost in air, and environment temperature is caused to rise, in addition Resistant heating there are one disadvantage just
It is that service life is short, timing is needed to replace heater.
In addition we often may require that the colored mold product of printing, different colors need different materials in producing
Printing, and general 3D printer can only print a kind of material, this is because printed material is the fluid of thick thawing, replace
When pigment cannot as common print machine nozzle quick response, and nozzle layering track on walk about be it is rapid, switch
Printed material cannot accurately be reloaded with a nozzle, even if being added to new material in nozzle, because of extruded material top
Mixed color phenomenon can also occur for unclean, and more conversion materials also centainly have delay, therefore just must to printing multiple color
The 3D printer of more nozzles must be used.
Utility model content
The purpose of this utility model is to provide a kind of more electromagnetic heating nozzle 3D printers, the sprays of 3D printer electromagnetic heating
Head greatly reduces scattering and disappearing for heater heat, improves the thermal efficiency, extend heating relative to traditional Resistant heating nozzle

Trunnion, be sleeved on trunnion and nozzle the shelf of junction, installation on the shelf and the electromagnetic heating coil that is socketed in outside trunnion；
Each trunnion is fixed on a sliding block.
As being further improved for said program, more electromagnetic heating nozzle 3D printers further include transmission shaft, are passed
One end of moving axis and servo drive motor axis connection, the other end of transmission shaft are fixedly mounted on motor housing.
As being further improved for said program, more electromagnetic heating nozzle 3D printers further include and multiple straight lines
The corresponding multiple stepper motors of slide unit, each stepper motor drive corresponding sliding block to be slided on corresponding straight line slide unit.
As being further improved for said program, the straight line slide unit uses synchronous banding pattern straight line slide unit.
As being further improved for said program, it is equipped between the electromagnetic heating coil and corresponding trunnion heat-insulated
Layer.
As being further improved for said program, the trunnion is metal tube.
As being further improved for said program, for the nozzle in cone, diameter is identical as throat pipe diameter.
A kind of more electromagnetic heating nozzle 3D printers of the utility model, make metal trunnion as quilt using electromagnetic heating technique
Calandria self-heating is considerably reduced scattering and disappearing for heat, improves the thermal efficiency, extend heater service life in this way,
In addition electromagnetic heating technique can also realize local heating, therefore can be omitted cooling device of the trunnion close to catheter end, simplify
Equipment composition.In addition the convenient switching when design of more nozzles is convenient for printing color model product between different materials nozzle,
Mixed color phenomenon is avoided, production efficiency is greatly improved.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with specific embodiment
The utility model is described in further detail, it should be understood that specific embodiment described herein is only used for explaining this
Utility model is not used to limit the utility model.
Refering to fig. 1, the utility model provides a kind of more electromagnetic heating nozzle 3D printers comprising servo drive motor
1, transmission shaft 2, motor housing 3, multiple stepper motors 4, multiple straight line slide units 5, multiple electromagnetic heating nozzles.
One end of transmission shaft 2 and 1 axis connection of servo drive motor, the other end of transmission shaft 2 are fixedly mounted on motor housing 3
On.It is rotated by 2 driving motor case 3 of transmission shaft by servo drive motor 1.Multiple straight line slide units 5 are centered on motor housing 3, edge
The direction of rotation of motor housing 3 is equipped with a sliding block 6 around layout on motor housing 3, and each on straight line slide unit 5.Straight line slide unit 5
Using synchronous banding pattern straight line slide unit.Multiple corresponding multiple stepper motors 4 of straight line slide unit 5, each stepper motor 4 drive accordingly
Sliding block 6 slides on corresponding straight line slide unit 5.
Multiple electromagnetic heating nozzles include nozzle 7, trunnion 8, shelf 9, electromagnetic heating coil 10.Nozzle 7 can be in cone,
Its diameter is identical as 8 diameter of trunnion.One end of trunnion 8 is connected with nozzle 7.Shelf 9 can be sleeved on the connection of trunnion 8 and nozzle 7
Place.Electromagnetic heating coil 10 can be mounted on shelf 9, and be socketed in outside trunnion 8.Trunnion 8 is made of metal.Electromagnetic heating line
Thermal insulation layer 11 is installed between circle 10 and trunnion 8, prevents 8 heat of trunnion to generate heat to external diffusion.Each trunnion 8 is fixed on one
