Description
Technical field
It the utility model is related to 3D printer technical field, specially a kind of extrusion structure applied to 3D printer.
Background technology
Existing 3D printer extrusion structure is generally made up of feed device, trunnion, heated nozzle.Wherein feed device is by step
Stepper motor drives, and material is delivered into heated nozzle by conduit and is operated.This extrusion structure is easily met in real work
The problems such as to plug, therefore, we release a kind of extrusion structure applied to 3D printer.
Utility model content
The purpose of this utility model is to provide a kind of extrusion structure applied to 3D printer, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the utility model provides following technical scheme：A kind of extrusion knot applied to 3D printer
Structure, including feed device, the front end of the feed device are provided with the first cooling fan, and the bottom of the feed device, which is fixed, to be connected
Installing plate is connected to, the upper end of the installing plate is provided with the second cooling fan, and the lower end of the installing plate is provided with ventilation duct, institute
State it is placed in the middle on front side of the lower end of feed device be connected with peek pipes, the lower ends of the peek pipes is provided with nozzle, the nozzle it is outer
Side surface is provided with heat block.
Preferably, the exit of the ventilation duct and the lower end of nozzle are located at the same horizontal position.
Preferably, the connected mode of the peek pipes and nozzle is to be spirally connected.
Preferably, it is mounted on plastic protection guard on the outside of first cooling fan and the second cooling fan.
Compared with prior art, the beneficial effects of the utility model are：The utility model is simple in construction, uses peek pipe generations
For trunnion, reduce material thawing of being heated at peek pipes and cause putty, when printer at work, the work of the second cooling fan,
Cooling wind can be blowed to the material of nozzle extrusion via ventilation duct, prevent heat from up spreading；The utility model can effectively improve
The problem of putty.

The exit of the ventilation duct 5 is located at the same horizontal position with the lower end of nozzle 8；
The connected mode of the peek pipes 6 and nozzle 8 is to be spirally connected；
The outside of the cooling fan 3 of first cooling fan 2 and second is mounted on plastic protection guard.
Specifically, in use, replacing trunnion using peek pipes 6, the heated thawing at peek pipes 6 of reduction material causes to block up
Material, when printer at work, material is delivered to nozzle 8, by adding by feed device 1 by driving stepper motor by peek pipes 6
Hot block 7 heats material, meanwhile, the second cooling fan 3 works, and can will cool down wind and blow to the material that nozzle 8 extrudes via ventilation duct 5
Material, heat is prevented up to spread.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
