The utility model discloses by realizing extruding, stop and the velocity of flow of accurate control material with extruding the first step motor who is connected, let the material be in accurate controllable state, the utility model discloses place alone because of the storage tank, can not increase the load of 3D printer because of increaseing the storage tank capacity, can design the storage tank capacity great, can print more large -scale object by 3D. The utility model discloses a feeding system can extensively be used in and print on all 3D printers that glue thick form, paste material.
Description
Technical field
The utility model relates to 3D and prints field, particularly relates to a kind of feeding system of 3D printer.
Background technology
3D printing technique is also known as rapid prototype manufacturing (RapidPrototypingManufacturing) technology, be born in the later stage eighties 20th century, it is the high-new manufacturing technology of one based on material stacking method, be considered to the great achievement manufacturing field over nearly 20 years, and be called as the third time industrial revolution.It integrates mechanical engineering, CAD, reverse Engineering Technology, Layered Manufacturing Technology, Numeric Control Technology, material science, laser technology, automatically can change the prototype or direct finished parts with certain function, directly, quickly and accurately by design philosophy into, thus be the realization rate that the aspects such as the verification of part prototype, newly design philosophy provide a kind of high efficiency, low cost.In fact 3D printing technique is exactly the data utilizing three-dimensional CAD, by 3D printer, material stacking is from level to level become physical prototypes.
Present 3D printing technique has no longer been confined to the application of industrial circle, start to combine with other industry, develop polytype 3D printer, a class is wherein had to be with thick, half thick or pasty masses is printed material, as 3D prints chocolate, 3D prints batter, 3D prints pottery mud, 3D prints various paste colloid substances etc., the feeding system of this kind of 3D printer is most and syringe is similar, printed material is contained in syringe, with driven by motor piston, printed material is extruded, or material is extruded by direct air pressure, such feeding system advantage is that structure is simple, cost is low, shortcoming is that capacity is little, material often has certain elasticity of compression and uncontrollable " acting freely ", material and printhead are structure as a whole, add printhead weight, reduce print speed.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of Large Copacity for 3D printer, accurately can controls extrusion capacity, strengthen storage tank capacity and can not increase the feeding system of printhead weight.
The technical scheme that the utility model technical solution problem adopts is: the feeding system of 3D printer, be connected with pressure source, constant-voltage equipment, pressure-release assembly, storage tank, feed pipe, extruder head and nozzle in turn, described extruder head is provided with stepper motor, and described stepper motor controls by extruding control system.
Further, described pressure source is air compressor machine or hydraulic press.
Further, described pressure source is the forcing press that electric screw pushes.
Further, described extruder head inside is provided with the rotating shaft of helicitic texture, and drives rotating shaft to rotate by stepper motor.
The beneficial effects of the utility model are: the utility model is only responsible for printed material to push to extruder head inside through the pressure that constant-voltage equipment regulates, and in addition realized accurately controlling the extruding of material by the stepper motor be connected with extruder head, stopped and flow velocity, allow material be in controllable precise state; The utility model is placed separately because of storage tank, can not increase the load of 3D printer because strengthening storage tank capacity, can must be larger by storage tank Capacity design, can print larger object by 3D.Feeding system of the present utility model can be widely used in print all thick, creamy material 3D printer on.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, feeding system for 3D printer of the present utility model is connected with pressure source, constant-voltage equipment, pressure-release assembly, storage tank, feed pipe, extruder head and nozzle in turn, extruder head is provided with stepper motor, and stepper motor controls by extruding control system.
Above-mentioned pressure source can be air compressor machine, hydraulic press; Also can be the forcing press etc. that electric screw pushes, the no matter pressure source of which kind of form, all and can stop producing pressure oscillation because of the startup of motor; The constant-voltage equipment be connected with pressure source plays the effect exporting constant pressure, also has the effect regulating pressure size simultaneously, ensures the material in storage tank to be delivered to equably in extruder head by feed pipe; Pressure-release assembly has the function turning on and off the pressure exported by constant-voltage equipment, also have when turning off pressure simultaneously and discharge the effect remaining in storage tank, feed pipe internal pressure, to ensure that extruder head accurately can control material and to extrude from nozzle and to stop under the effect of stepper motor, and there will not be because allow material continue the situation of trickling under the effect of residual pressure; Storage tank is used for storage material, and one end is from pressure-release assembly cut-in pressure, and material is delivered to extruder head inside by feed pipe by the other end; Stepper motor is arranged on extruder head, is extruded by material under the effect of extruding control system by nozzle, and can control extruded velocity and start and stop easily; Extruder head inside is provided with the rotating shaft of helicitic texture, and drive rotating shaft to rotate by stepper motor, by printed material extrusion nozzle, the parameters such as the direction rotated by control step motor, speed, what accurately can control printed material extrudes state.
Current feed mode is generally pressure source-constant-voltage equipment-storage tank-nozzle, pressure is utilized directly to extrude printed material in storage tank, change output pressure size by regulating constant pressure device and change the speed that material extrudes, effectively can not control extruding and stopping of material in continuous high frequency rate ground in print procedure, this just makes the model pattern limitation printed.
The utility model is different from traditional direct feed mode, the pressure regulated through constant-voltage equipment is only responsible for printed material to push to extruder head inside, and in addition realized accurately controlling the extruding of material by the stepper motor be connected with extruder head, stopped and flow velocity, allow material be in controllable precise state.
