Abstract
A kind of FDM type 3D printing extruders for preventing wire rod caking from blocking, are related to 3D printing rapid shaping and 3D printer industrial design field.The extruder includes wire squeeze gear, godet roller, sliding block, and spring;Godet roller is fixed on a sliding block, this sliding block only slides up and down a freedom of motion in an extruder;This sliding block is combined by two or more spring with extrusion motor spindle;Wire squeeze gear and the arrangement of godet roller vertical direction, and make the line in two centers of circle perpendicular to wire rod moving direction;Wire squeeze gear is fixed on stepper motor.During taking out wire rod after printhead caking, since pimple can extrude godet roller, godet roller can be moved downward with movable slider, and godet roller moves downward at this time, so that being exited with scabbed wire rod from extruding strings device, it is no longer necessary to dismantle extruder.And normally into when wire vent, spring is subject to power to be insufficient to allow its compression.
Description
Technical field
It the utility model is related to 3D printing rapid shaping and 3D printer industrial design field.
Background technology
Fused glass pellet technology (Fused Deposition Molding, FDM) is by Scott Crup Scotts
Ke Lunpu invented successful rapid shaping technique in 1989.Stratasys companies have been founded in he or she in 1992, have been sold
First FDM type 3D printers, open the commercialized gate of FDM type 3D printers.FDM technology is to use plastics silk material, such as ABS
Or PLA, as printing raw material, printing wire rod is squeezed to printing and met and discussed by the printing head of printer, there is one on printing head
Silk material is melted into viscoid by a heating module, by printing head by printing consumables be coated on model section profile traces and
Fill on track.
But in actual application, the user of FDM type 3D printers is frequently encountered the situation of printing head blocking,
At this time, the wire rod melted before in nozzle heating module will form a pimple (following such a phenomenon is referred to as wire rod
Caking phenomenon).The pimple produced to take out caking needs to take out wire rod from at silk mouth at this time, but during this usually
The pimple that the situation of appearance generates when being and blocking can be blocked in the gear parts of extruder.At this time, extruder can only be dismantled by silk
Material takes out.It is a troublesome job for desktop level user although the not so difficult completion of process.
Utility model content
, can not after special solution printer caking the utility model proposes a kind of new FDM type 3D printing extruders
Move back the phenomenon of silk.
A kind of FDM type 3D printing extruders for preventing wire rod caking from blocking, it is characterised in that:The extruder includes wire squeeze tooth
Wheel, godet roller, sliding block, and spring;
Godet roller is fixed on a sliding block, this sliding block only slides up and down a freedom of motion in an extruder;
This sliding block is combined by two or more spring with extrusion motor spindle;
Wire squeeze gear and the arrangement of godet roller vertical direction, and make the line in two centers of circle perpendicular to wire rod moving direction;Wire squeeze
Gear is fixed on stepper motor, it is controlled into silk or wire vent by motor.
For the utility model compared to conventional extruder, difference lies in be that guide roller is fixed on one and may only move up and down
Sliding block on, sliding block by compress spring with extrusion motor spindle be connected.Such design is advantageous in that, is taken out after printhead caking
During wire rod, since pimple can extrude godet roller, godet roller can be moved downward with movable slider, and godet roller is transported downwards at this time
It is dynamic, so that being exited with scabbed wire rod from extruding strings device, it is no longer necessary to dismantle extruder.And normally into wire vent when
Wait, spring is subject to power to be insufficient to allow its compression.Other parts and conventional extruder construction are identical.
Brief description of the drawings
Fig. 1 is the FDM type 3D printing extruder structure figures designed in the utility model
1-wire squeeze gear 2-godet roller, 3-sliding block, 4-spring, 5-wire rod
Embodiment
A kind of FDM type 3D printing extruders for preventing wire rod caking from blocking, it is characterised in that:The extruder includes wire squeeze tooth
