Detailed description of the invention
For the ease of understanding the present invention, below with reference to relevant drawings, the present invention is described more fully.Preferred embodiment of the present invention is given in accompanying drawing.But the present invention can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present invention more comprehensively thorough.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present invention understand usually.The object of term used in the description of the invention herein just in order to describe specific embodiment, is not intended to limit the present invention.Term as used herein "and/or" comprises arbitrary and all combinations of one or more relevant Listed Items.
Fig. 1 is the extrusion mechanism schematic diagram of an embodiment 3D printer, and Fig. 2 is the schematic diagram of the end cap of motor housing side embodiment illustrated in fig. 1, and Fig. 3 is the schematic diagram that extrusion mechanism embodiment illustrated in fig. 1 transmits printed material.
Incorporated by reference to Fig. 1, Fig. 2 and Fig. 3, a kind of 3D printer, comprises extrusion mechanism, and described extrusion mechanism comprises driving wheel 30, driven pulley 20 and motor 10.Extension motor shaft 40 on the end cap 12 of motor 10 side; The end cap 12 of motor 10 offers installing hole 14.Driving wheel 30 is arranged on the extension of motor shaft 40, and driven pulley 20 is arranged on the end cap 12 of motor 10 by installing hole 14, and driving wheel 30 and driven pulley 20 cooperatively interact to rotate and transmit printed material 60 to extrude.Printed material 60 can be strip, and can be also lengthy motion picture shape, material comprises plastic cement, metal etc.
In the present embodiment, driving wheel 30 is gear.Driving wheel 30 and motor shaft 40 removably connect, and make it possible to change the different driving wheel 30 of size.Driven pulley 20 also can be removably connected by the end cap 12 of installing hole 14 and motor 10, makes it possible to change the different driven pulley 20 of size.Change the printed material 60 that the driving wheel 30 of different size or driven pulley 20 can adapt to different-thickness or diameter.Installing hole 14 is screwed holes, and driven pulley 20 is arranged on the end cap 12 of motor 10 by installing hole 14 and driven pulley fixed screw 50 cooperation.Installing hole 14 also can be circular hole, and driven pulley 20 is riveted by installing hole 14 or alternate manner is directly fixed on end cap.The fixed form of design driven pulley 20 like this, structure is simple, it is very convenient to install.
Motor shaft 40 being installed driving wheel 30, by setting modulus, the number of teeth parameter of driving wheel 30, the extruded velocity of printed material 60 can be controlled.Driven pulley 20 is fixed on the end cap 12 of motor 10, coordinate with driving wheel 30, between driving wheel 30 and driven pulley 20, insert printed material 60, printed material 60 inserts rear main wheel 30 and coordinates together with driven pulley 20 and can keep certain pressure to the printed material 60 inserted.Clearance D between the wheel rim of driving wheel 30 and the wheel rim of driven pulley 20, by thickness or the diameter decision of printed material 60.Generally, if printed material 60 is elongate configuration, then the clearance D 0.2-0.7mm less of the path length of printed material 60 between the wheel rim of driving wheel 30 and the wheel rim of driven pulley 20; If printed material 60 is lengthy motion picture structure, then the gap 0.2-0.7mm less of the thickness of printed material 60 between the wheel rim of driving wheel 30 and the wheel rim of driven pulley 20.According to the difference of printed material 60, clearance D also can be other numerical value.Drive driving wheel 30 rotary motion when motor rotation, drive printed material 60 travel forward and drive driven pulley 20 counter-rotation, driving wheel 30 matches with driven pulley 20 printed material 60 to extrude and is sent in fusion pool 70.Driving wheel 30 and driven pulley 20 are fixed on motor component simultaneously, do not have other part extra collocation, and both fit structure is simple, precision is high, easily install.
As shown in Figure 4, the further technical scheme of the present invention is: on the wheel rim of driving wheel 30 and/or the wheel rim of driven pulley 20, in rotational direction offer bathtub construction 32, when printed material 60 inserts the clearance D between the wheel rim of driving wheel 30 and the wheel rim of driven pulley 20, can be stuck in bathtub construction 32.When driving wheel 30 and/or driven pulley offer bathtub construction 32, the clearance D between driving wheel 30 and driven pulley 20 can suitably reduce.Printed material 60 is constrained in bathtub construction 32, and the process being transported to fusion pool 70 can not laterally offset or swing, further increases the precision of printing.
Above-mentioned 3D printer, improve at extrusion mechanism, driven pulley is directly fixed on the end cap of motor housing by installing hole, driving wheel is arranged on motor shaft, all directly be fixed on motor component by driving wheel and driven pulley, whole extrusion mechanism is only made up of 3 parts, improves the quality of fit of driving wheel and driven pulley with the many part fits of tradition compared with the extrusion mechanism formed.The end cap of motor housing offers installing hole, and simplify the installation fixation procedure of driven pulley, structure is simple, installation and debugging are convenient, production efficiency is high.
On the wheel rim of the wheel rim of driving wheel and/or driven pulley, in rotational direction can also be provided with bathtub construction, printed material is stuck in bathtub construction, control printed material, in motion process, laterally offset or swing can not occur, further increase printing precision.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
