Description
Technical field
The present invention relates to a kind of 3D printer short range shred feeding spray nozzle device and methods, belong to the field of 3D printing equipment.
Background technology
In recent years, with the gradual maturation of 3D printing technique, 3D printer especially desktop 3D printer becomes increasingly
It is universal.The wire feeder of FDM (Fused Deposition Modeling, fused glass pellet) desktop 3D printer mainly divides
For two kinds of long-range wire feeder and process wire feeder, wherein remotely wire feeder uses relatively broad, but in long-range wire feed
In mechanism, there is longer one section of consumptive material to rest between wire feeder and nozzle, can become in this way because of the plasticity of silk material (consumptive material)
Shape causes in wire feed and there is delay during move back silk, occurs wire drawing or virtual connection phenomenon when so as to cause printer model；Though
Right short range wire feeder more closely avoids the wire drawing caused by the plastic deformation of silk material (consumptive material) because of wire feeder and nozzle distance
Or virtual connection phenomenon, but this also requires to have between nozzle and wire feeder stronger heat-sinking capability, to be avoided silk material (consumption simultaneously
Material) softening in advance.
The short range wire feeder that most of desktop 3D printer uses currently on the market, since its structure design etc. is deposited
Defect, it is easy to cause wire feed difficult, radiating treatment is improper between nozzle and wire-feed motor causes silk material (consumptive material) to melt in advance
Change so as to cause nozzle plug, the problems such as dredging nozzle is difficult after plug.Such as Chinese patent CN205238588U discloses one
The wire rod extrusion mechanism of the entitled FDM formulas 3D printer of kind, nozzle is closer with extruder distance, by heat loss through convection, exists
The technological deficiency that consumptive material softens in advance.
In addition, in the wire rod extrusion mechanism of printer, usually elastic force is provided to hold-down mechanism so that compacting machine using spring
Silk material (consumptive material) is pressed on driving wheel by structure, but this mode can not adjust the compression journey between hold-down mechanism and driving wheel
Degree；In order to solve this problem, one end of above-mentioned spring can be also fixed to by rotary screw on fixed frame by the prior art, be led to
The rotation of rotary screw is crossed to the compression degree of adjustable hold-down mechanism and driving wheel；However after rotary screw adjusts every time,
The elastic force of above-mentioned spring will be maintained at the state after screw adjustment, if user wants the compression degree before recovery, it is necessary to weight
New adjustment rotary screw, for those needs frequently 3D printer of adjustment compression degree, aforesaid way is difficult accurately to return
Original compression degree is returned, and cumbersome, is also easy to that screw spinning is caused to lose original function, most important, above-mentioned adjustment
Mode is easy to cause wire feed difficulty/consumptive material and stacks, and causes to print failure/damage printer；In addition, significantly for certain needs
The occasion for adjusting the compressions degree of hold-down mechanism and driving wheel, if predetermined adjustment amplitude is not achieved, also result in wire feed difficulty/
Consumptive material stacks, so as to cause printing failure/damage printer；In addition, above-mentioned spring breaking down, also results in hold-down mechanism from wire rod
It falls off in extrusion mechanism, printing is caused to fail.
To sum up, most of desktop 3D printer wire-feed motor mechanism in the prior art cannot meet existing well
Stage is for the higher and higher demand for development of desktop 3D printer performance.
