Description
Technical field
3D printing technique field is the utility model is related to, especially a kind of 3D printing extrusion mechanism of no spring.
Background technology
FDM (" Fused Deposition Modeling " shorthand, as fused glass pellet) 3D printers
3D models are printed using the forming principle of fused deposition.Traditional FDM 3D printer extrusion mechanisms, will be solid by spring force
Consumptive material between fixed wheel and guide wheel clamps so that frictional force between extruder gear and consumptive material, extruder motor drive consumptive material to
Extrude shower nozzle discharging and complete printing extrusion consumptive material process.
The extrusion mechanism is complicated, cumbersome, it is necessary to artificially spring press is gone down, and then plugs consumptive material again, and because
To there is spring, the hole slot of feeding is discontinuous, easy off normal when plugging consumptive material, bad operation.And soft consumptive material TPU can not be printed
(TPUE) and TPE (thermoplastic elastomer (TPE)).
Utility model content
The utility model provides a kind of 3D printing extrusion mechanism of no spring, simple in construction, charging reload it is convenient and swift, directly
Consumptive material plug can be completed to operate by connecing.
The utility model specifically adopts the following technical scheme that realization：
A kind of 3D printing extrusion mechanism of no spring, including extruder motor, material folding block, charging guide bearing, charging are synchronously
Wheel, supporting plate, trunnion and shower nozzle, the material folding block are fixed on the extruder motor, the output shaft of the extruder motor and institute
Charging synchronizing wheel connection is stated, the charging guide bearing is fixed on inside the material folding block, and the extruder motor is arranged on described
In supporting plate, the both ends of the trunnion connect the material folding block and shower nozzle respectively.
Preferably, the material folding block, from top to bottom through there is charging hole, the charging hole both sides offer bearing respectively
Mounting hole and synchronizing wheel mounting hole, the material folding block are arranged on the extruder motor by two screwed holes of upside.
Preferably, also including fixed block, described fixed block one end is arranged in the supporting plate, and the other end holds institute
State material folding block.
Preferably, the shower nozzle is arranged in heat block, the temperature of the heat block is 200 DEG C~250 DEG C.
A kind of 3D printing extrusion mechanism of no spring provided by the utility model, its advantage are：
1st, extrusion part can be simplified, spring and guide wheel clamp mechanism is omitted completely, reduces structure complexity, Yong Hudan
Hand is operable；
2nd, compared to the extruder structure of conventional springs fixture, softer elastic TPU even TPE elasticity consumptive materials can be printed；
3rd, hole wall rigidity inside charging hole ensures the feedstock direction of consumptive material, will not bend.

Embodiment
To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model discloses
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the 3D printing extrusion mechanism for a kind of no spring that this implementation provides, including extruder motor 1, material folding
Block 2, charging guide bearing 3, charging synchronizing wheel 4, supporting plate 5, fixed block 6, trunnion 7, shower nozzle 8 and heat block 9.Material folding block 2 is logical
Two screwed holes 21 for crossing upside are arranged on extruder motor 1, and the output shaft of extruder motor 1 is connected with charging synchronizing wheel 4, and is entered
Expect that synchronizing wheel 4 is arranged in the synchronizing wheel mounting hole 22 of material folding block 2, charging guide bearing 3 is arranged on the bearing inside material folding block 2
It is charging hole 24 in mounting hole 23, between synchronizing wheel mounting hole 22 and bearing mounting hole 23, charging hole 24 is from top to bottom through whole
Individual material folding block 2, extruder motor 1 are arranged in supporting plate 5, are padded again between material folding block 2 and supporting plate 5 and set fixed block 6, trunnion 7
One end be connected with the charging hole 24 of material folding block 2, the other end is connected with shower nozzle 8, and heat block 9 heats to shower nozzle 8, and temperature can
Up to 200 DEG C~250 DEG C.
The operation principle of the application is as follows：The generally circular in cross section strip consumptive material of printed material used in 3D printing, diameter
About 1.75mm, charging hole insertion of the printed material above material folding block, reaches charging synchronizing wheel and feeds the position of guide bearing
When, charging guide bearing and charging synchronizing wheel can clamp consumptive material, now with the rotation of extruder motor, charging synchronizing wheel also one
With rotation, and then consumptive material feeding downwards is driven, under the drive of synchronizing wheel, consumptive material is by trunnion, arrival nozzle position, shower nozzle
In the presence of heat block, temperature is increased to 220 DEG C, and consumptive material reaches the fusing point of itself, can be melted into stream shape, and from shower nozzle
Discharging opening is extruded, and passes through the regular movement of extrusion mechanism, the consumptive material coagulation forming of extrusion, layer upon layer, it is possible to print
Threedimensional model.
