Abstract
A kind of 3D printer extruder, including frame, frame fixes driving wheel, it is feeding gap between driving wheel and friction pulley, wire feed hole is connected above feeding gap, wire-feeding pipe is connected below, wire-feeding pipe is provided with heater, the frame is provided with slideway, and sliding block is provided with slideway, and sliding block can be slided in the slideway.One end fixed friction wheel of sliding block, stage clip is provided between the other end and frame of sliding block.Relative to prior art, friction pulley is being designed as activity by the utility model, is adapted to the material silk of different-diameter, and will not malfunction the phenomenons such as skidding, and production efficiency is higher.In addition, it is also very convenient to install material silk.
Description
Technical field
The utility model is related to a kind of part of 3D printer.
Background technology
Present 3D printer will expect silk generally by the extruder on printhead（Printing raw material）Wire feed, heating become
It is soft, while printhead runs to correct position, the material silk solidification forming that printhead spues, as works.It is dynamic that material silk is extruded
Power is a driving wheel and a friction pulley, the gap between this two wheels of material silk card（Call feeding gap in the following text）In, in driving wheel
Moved under drive with the frictional force of its own.
Utility model content
The technical problems to be solved in the utility model is：Expect that the diameter of silk differs, and between driving wheel and friction pulley
Gap fix, if material silk diameter it is too small, driving wheel to its frictional force it is too small and occur skid, cannot move it；Such as
Fruit material silk diameter is too big, highly difficult by feeding gap by material silk is installed.
To solve the above problems, the purpose of this utility model is to provide a kind of adjustable 3D printer extrusion in feeding gap
Machine.
The technical solution of the utility model is specially：
A kind of 3D printer extruder, including frame, frame fix driving wheel, are feeding between driving wheel and friction pulley
Gap, connects wire feed hole above feeding gap, wire-feeding pipe is connected below, and wire-feeding pipe is provided with heater, and the frame is provided with
Slideway, is provided with sliding block in slideway, sliding block can be slided in the slideway.One end fixed friction wheel of sliding block, the other end of sliding block with
Stage clip is provided between frame.
The sliding block extends to the outside of frame.
The frame is provided with projection, and the end of stage clip is set in the outside of projection.
The driving wheel is fixed on driving shaft.
Relative to prior art, friction pulley is being designed as activity by the utility model, is adapted to the material of different-diameter
Silk, will not malfunction the phenomenons such as skidding, and production efficiency is higher.In addition, it is also very convenient to install material silk.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is the generalized section of extruder main driving wheel position.
Specific embodiment
Such as accompanying drawing 1, Fig. 2, a kind of 3D printer extruder, including frame 1, frame 1 fix driving wheel 41, driving wheel 41
It is feeding gap between friction pulley 42, wire feed hole is connected above feeding gap, wire-feeding pipe 2 is connected below, wire-feeding pipe 2 is provided with
Heater 3, frame 1 is provided with slideway, and sliding block 5 is provided with slideway, and sliding block 5 can be slided in the slideway.One end of sliding block 5 is fixed
Friction pulley 42, stage clip 51 is provided between the other end and frame 1 of sliding block 5.
Sliding block 5 is pressed for convenience, and sliding block 5 extends to the outside of frame 1.
Stage clip is fixed for convenience, and frame is provided with projection 52, and the end of stage clip 51 is set in the outside of projection 52.
Driving wheel 41 is fixed on driving shaft 4.
Its work was originally：
When more reloading thread, first with hand to material silk direction（Left side in Fig. 2）Pressing sliding block, drives friction pulley also same time shift
It is dynamic, feeding gap is become big, material silk conveniently can be passed through into feeding gap, then hand is unclamped, stage clip resets, band movable slider and
Friction pulley resets, and makes friction pulley, driving wheel larger with to expecting the pressure of silk, it is sufficient to make driving wheel drive material silk to move.
Above-described is only preferred embodiment of the present utility model, it is noted that for those skilled in the art
For, under the premise of the utility model general idea is not departed from, some changes and improvements can also be made, these should also be considered as
Protection domain of the present utility model.
