Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The novel 3D printhead of a kind of fast assembling-disassembling as shown in figures 1 to 6, comprise heat block 2 and shower nozzle 1, shower nozzle 1 is installed on the lower end of heat block 2, heat block 2 is connected with trunnion 3, in trunnion 3, be provided with the silk material pipeline 31 be communicated with shower nozzle 1 in heat block 2, trunnion 3 is provided with asymmetric flank 4; Asymmetric flank 4 is installed on pedestal 5, and pedestal 5 is provided with the mounting groove 50 mated with asymmetric flank 4, and asymmetric flank is arranged in mounting groove.Asymmetrical flank can prevent reverse installation, and also without the need to debugging repeatedly, direct observable goes out correct installation direction.In silk material pipeline 31, arrange instlated tubular 30, when silk material 12 is sent into by wire feeder, instlated tubular 30 can avoid a material 12 heated bending too early.
Heat block 2 is one-body molded with trunnion 3, shower nozzle 1 preferably adopts the mode that is threaded and heat block 2 fixing, trunnion 3 and asymmetric flank 4 one-body molded, be decussate texture.The heat block of existing conventional printhead is two parts be separated with trunnion, when mounted, before this shower nozzle and trunnion had been arranged on heat block, and then trunnion is screwed into is fixed on pedestal, carry out spacing by a nut to it again, but this mode can exist following shortcoming: one is be and the assembling mode of instability with nut fixed choke, and in use nut easily loosens, thus affect the stable of trunnion and shower nozzle; Two is, when regulating shower nozzle to specified altitude assignment, may cause heat block malposition; Or time heat block position is positive, the height of trunnion but also exists individual difference; Above shortcoming can affect the final product quality printed, and also can be unfavorable for batch production.Therefore in this novel print head design, heat block and trunnion are formed in one, the mode that shower nozzle is threaded connection and heat block are connected and fixed, then its entirety are arranged on from the side on pedestal by flank, just solve simple installation and mounting spray head respectively to the problem of location.
Wire feeder comprises motor 9, wire feeding gear 10 and return idler 11, and pedestal 5 is installed on motor 9, and wire feeding gear 10 is installed in the rotating shaft of motor 9; Be formed with the space for carrying a material between return idler 11 and wire feeding gear 10, the output in space is corresponding with the input of silk material pipeline 31.Open motor 9, wire feeding gear 10 starts to rotate, when silk material 12 enters into the space between wire feeding gear 10 and return idler 11, wire feeding gear 10, roller compression with promote under enter in a material pipeline 31, be extruded by heat block 2 melting at shower nozzle 1 place.
The operation logic of wire feeding gear 10 and return idler 11: when silk material 12 is sandwiched between wire feeding gear 10 and return idler 11, because wire feeding gear 10 can rotate under the driving of motor 9, groove on wire feeding gear 10 and produce enough strong frictional force between silk material, by it toward conveying in silk material pipeline 31, and return idler 11 can followed by rotation.For the good position by silk material limits relatively, the circumferential edges along return idler 11 is formed with a holding tank 110, and holding tank 110 can avoid material sideslip in course of conveying.
Wire feeder also comprises compression swing arm 6, Compress Spring 7; The central part 60 of compression swing arm 6 is rotating to be installed on motor 9, compress between the transverse end 61 of swing arm 6 and pedestal 5 and be provided with Compress Spring 7, be equipped with adjusting screw(rod) 8 in Compress Spring 7, the top of adjusting screw(rod) 8 exposes to transverse end 61, and end and the pedestal 5 of adjusting screw(rod) 8 are connected and fixed; Return idler 11 is installed on the longitudinal direction end 62 compressing swing arm 6.
When the design of adjusting screw(rod) 8 makes independent dismounting heat block 2, wire feeder and pedestal 5 can not become loose, heat block 2 and wire feeder separate, simplify dismounting.Amount of spring compression can be adjusted thus the thrust of change return idler 11 by different adjusting screw(rod) 8 degree of depth, change the elasticity between wire feeding gear 10 and driven gear 11, pore size is between the two changed, to adapt to the delivery requirements of different silk material.
As tightened by adjusting screw(rod) 8, compress swing arm 6 with central part 60 for fulcrum rotates, transverse end 61 by Compress Spring 7 compression a little, and longitudinally holds 62 can outwards move, the void enlargement between wire feeding gear 10 and return idler 11; As unscrewed by adjusting screw(rod) 8, the transverse end 61 compressing swing arm 6 can upwards be pushed up by the reset strength of Compress Spring 7, and after compression swing arm 6 rotation, longitudinally end 62 can inwardly move, and the space between wire feeding gear 10 and return idler 11 reduces.When the apparatus is in the idle state; there is not a material between wire feeding gear and return idler, unnecessary collision friction occurring, by adjusting adjusting screw(rod) for avoiding both; the spacing that return idler and wire feeding gear can be made to keep stable, plays the effect of protection wire feeding gear groove.
Compression swing arm 6 arranges wire feed hole 63, and for being sent into by silk material, wire feed hole 63 is preferably arranged on position corresponding above space between wire feeding gear 10 and return idler 11.
Pedestal 5 is provided with three screw rods, first screw rod 51 is fixed on motor 9 through pedestal 5, and the second screw rod 52 is fixed on pedestal 5 through asymmetric flank 4, and the 3rd screw rod 53, successively through asymmetric flank 4, pedestal 5, is then fixed on motor 9.After removing the first, the 3rd screw rod 53, whole pedestal 5 departs from motor 9; After removing second, third screw rod 53, asymmetric flank 4 departs from pedestal 5, the convenient dismounting demand to different structure.
Wherein shower nozzle material is copper, and injection diameter is 0.2mm or 0.4mm, and instlated tubular is made up of Teflon (PTFE) material, and METAL HEATING PROCESS block is aluminium block, and its material pipeline section is circular.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit the scope of the utility model protection with this, change and the replacement of any unsubstantiality that those skilled in the art does on basis of the present utility model all belong to the utility model scope required for protection.
