Description
Technical field
The utility model relates to the three-dimensional printer based on the fused deposition quick shaping process, particularly relates to a kind of three-dimensional printer extruder head of changeable feeding.
Background technology
Being to use diameter based on the three-dimensional printer of fused deposition quick shaping process is plastics silk material about 1～2mm, by computer-controlled printing extruder head with plastics silk material melt extruded become about 0.2～0.4mm filament and successively scanning and printing be piled into three-dimensional body.Usually, the fused deposition quick shaping process need add support when manufacturing has the object of cantilever design.If the three-dimensional printer extruder head has only single fusion runner project organization, the object of printing and support can only make up with commaterial.Although in print procedure, can make support section become comparatively loose to reach the purpose of being convenient to peel off by the method for operation of control extruder head, but owing to be to use commaterial, be difficult to identification after printing is finished on the border of object and support and cause and peel off difficulty, support and also cause the damage of object fine structure when peeling off easily.In addition, the extruder head of single channel can't use the material of different colours or different performance to carry out composite printing.At present, three-dimensional printer extruder head based on the fused deposition quick shaping process adopts the dual channel structure more, one of them runner is used for melt extruding object moulding materials such as ABS plastic, and physics is peeled off or the backing material of chemical stripping but another runner is used for melt extruding.CN200780020529.8 and CN200820206342.9 disclose the design of two kinds of three-dimensional printer dual channel extruder heads respectively.The former uses a drive motors, makes by a cover complicated mechanical mechanism to melt extrude head and passive material feeding pressing wheel and realize that in the mode of swing the extrusion channel of moulding material and two kinds of silk material of backing material and feeding drive switching controls; The latter uses two drive motors respectively to moulding material and the independent switching controls that drives and realize the runner nozzle in the mode that mechanical elevating moves of backing material.Obviously, the former mechanical switching mechanism weight complicated and that increased the extruder head assembly is unfavorable for the flying print campaign of extruder head, and the latter uses two motors not only to increase cost but also increased the weight of extruder head assembly.Because above-mentioned disclosed two kinds of designs are when carrying out the switching of extruder head runner, the mechanical location of nozzle all needs to move and reset, thereby moving process very easily produces the dimensional accuracy that mechanical position error influences printing objects.The problem that need to solve be can realize as a kind of easy method how that feeding is switched in the printing of three-dimensional printer extruder head again can be because switching the stamp with the size precision that feeding influence object.
The utility model content
The utility model is at the problem and shortage that above-mentioned prior art exists, and providing a kind of serves as that the three-dimensional printer extruder head of printing raw material is printed the method for reloading and the implement device that reloads thereof when working with two kinds of filamentary materials.
For realizing above purpose, the utility model has been taked following technical scheme: a kind of three-dimensional printer extruder head of changeable feeding, include pedestal, feeding changeover module, described feeding changeover module is rotationally connected by first rotating shaft and pedestal, and the passive material feeding pressing wheel of feeding changeover module is located at the initiatively both sides of drawing-inroller respectively; The front portion of pedestal is equipped with two and prints silk material heating and melting runner, one is used for melt extruding the printing shaping material, one is used for melt extruding the printing backing material, and heating and melting runner one end connects respectively prints the silk material, and the other end connects respectively prints silk material extrusion nozzle.Printing the silk material is pressed on respectively between passive material feeding pressing wheel and the active drawing-inroller; Include a silk material drive motors that is installed on the pedestal, with the direct-connected active drawing-inroller of silk material drive motors, also comprise the interlock wabbler mechanism with bistable characteristic, drive mode that passive material feeding pressing wheel engages with drawing-inroller initiatively and carry out feeding and switch, carry out two kinds of switchings printings of printing the silk material; In the process that two kinds of printed materials switchings are printed, it is motionless that described printing silk material heating and melting runner and a printing silk material extrusion nozzle remain fixed-site respectively.
The utility model is applicable to and uses a feeding drive motors and can realize that two kinds of silk material alternately switch the three-dimensional printer extruder head design of feeding, when carrying out the feeding switching, the device (mechanism) that reloads drives by connecting rod, corresponding passive pinch roller is pressed on the silk material by realizing printing feeding on the motor-driven active drawing-inroller with suitable pressure, and add hot flow path and nozzle print and the process of reloading in to remain at the fixed position motionless, avoided because extruder head or nozzle switch the mechanical position error of bringing after mobile.Print active drawing-inroller and the driving of passive material feeding pressing wheel of silk material by driven by motor and enter corresponding fusion runner and extruded by nozzle, print three-dimensionally shaped that extruder head successively prints under the driving of XY motion.
Described three-dimensional printer extruder head is realized the switching of feeding under the effect of the passive material feeding pressing wheel that two interlocks are waved, when needs printing shaping material, the passive material feeding pressing wheel of moulding silk material side is pressed in moulding silk material under driving initiatively on the drawing-inroller having bistable wabbler mechanism, and drive motors rotates and drives initiatively drawing-inroller and send moulding silk material to the fusion runner and extruded by nozzle; When needs are printed backing material, the passive material feeding pressing wheel of supporting wire material side is pressed in the supporting wire material under driving initiatively on the drawing-inroller having bistable wabbler mechanism, and drive motors rotates and drives initiatively drawing-inroller (the initiatively direction of rotation of drawing-inroller rotation direction and moulding feeding) and send the supporting wire material to the fusion runner and extruded by nozzle.
Described interlock wabbler mechanism comprises elastic force expansion bend, connecting rod, one end of elastic force expansion bend is installed rotating shaft by pedestal and is connected with pedestal, the other end is installed rotating shaft by connecting rod and is connected with connecting rod one end, the other end of connecting rod is connected with first rotating shaft, connecting rod install rotating shaft also be located at pedestal on driving lever be connected; Connecting rod drives the swing of passive pinch roller by first rotating shaft and will print the silk material and be pressed on the active drawing-inroller.
