Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of one embodiment of 3D printer of the utility model；
Fig. 2 is the partial enlarged view in Fig. 1 at A.
Specific embodiment
A kind of embodiment of the 3D printer of the utility model, as shown in Figs. 1-2, including wire feeder 1 and spray head it is anti-blocking
Plug structure, spray head anti-blockage structure include spray head 2, and heating structure 3 is provided on spray head 2, and wire feed structure 1 and heating structure 3 are equal
Using existing wire feed structure and heating structure, and will not be described here in detail.Wedge surface is provided on the outer wall in the lower end exit of spray head 2
4, the top of wedge surface 4 is provided with protrusion 5 on the lateral wall of spray head, is connected with elastic batten 6 in protrusion 5.Elastic batten 6 has
The construction section 7 parallel with the axis of spray head, elastic batten further includes lower end abutting spray head lower end exit wedge surface and upper end is separate
The stretch section 8 of wedge surface.The quantity of protrusion 5 is three and is circumferentially spaced 90 degree of arrangements two-by-two, is provided in each protrusion above-mentioned
Elastic batten.
Guiding is equipped with guide plate 9 up and down in protrusion 5, and guide groove can be set between guide plate 9 and protrusion and realize guiding
Cooperation, the spray head anti-blockage structure further include the driving structure for driving guide plate to move up and down.Driving structure includes and leads
The screw rod 12 being threadedly coupled to the top of plate 9 and the driving motor 13 driven screw turns, wherein screw rod is rotatably dispose in wire feed
In mechanism, driving motor is also disposed in Song Ji mechanism.Guide plate have with protrusion up and down be oriented to cooperation guide section 10 and under
Portion is towards the wedge surface bending for squeezing stretch section in guide plate uplink so that the upper end of the stretch section is close to described
Wedge surface and lower end edge wedge surface protrude from the bending top splenium 11 of spray head.The lower end of the stretch section of elastic batten gradually becomes smaller for thickness
Tip 16, can preferably contact and pushing tow and the tamper for scraping tenesmus.Opening is provided on the wedge surface of spray head towards bullet
Property batten stretch section mounting hole 14, pressure spring 15 is installed, pressure spring has the protrusion for protruding from mounting hole in mounting hole
For stretch section press.The setting of pressure spring can be such that the stretch section of elastic strip plate resets, the elasticity without only relying on elastic batten
The elastic reset of Duan Benshen, reset is relatively reliable, also avoids using lower stretch section to deform for a long time so that only by elasticity
The elasticity of section can not reset completely, and the lower end of stretch section is made still to protrude from the lower port of spray head, lead to that lower section can be scraped
Printer model.
When the outlet of the lower end of spray head is blocked, melt drops and condenses, and drives guide plate edge by driving structure at this time
Raised guiding movement up and down, guide plate bending top splenium during uplink squeezes the stretch section of elastic batten, so that stretch section
Upper end is close to wedge surface and lower end edge wedge surface protrudes from spray head, the condensation top of tenesmus is scraped off, use is very convenient, saves
The step of manually cleaning, the problem of spray head easily scalds cleaning human hand and time saving and energy saving is avoided.Guide plate downlink
When by stretch section itself and the elastic force of pressure spring reset stretch section, the lower end of stretch section is retracted on wedge surface.It can be repeatedly anti-
Driving guide plate carries out the tamper of cleaning spray head lower end again, it is ensured that cleans out.
In the other embodiments of the utility model, raised quantity may be one, and protrusion can be ring flat-plate at this time
Or arc panel, three elastic battens are all set in the protrusion；Protrusion and elastic batten can also correspond, at this time protrusion and
The quantity of elastic batten can be adjusted according to actual needs, such as protrusion is one, and elastic batten is also one, and protrusion can also
Think two, the quantity of elastic batten may be two；Angle between three projection amount amounts can also be according to actual needs
It is adjusted.
