A kind of three-dimensional printer of synchronous wire feed
Technical field
the present invention relates to the three-dimensional printer in three-dimensional printer field, particularly a kind of synchronous wire feed.
Background technology
the three-dimensional printer of application fuse fusion stacking forming technique mainly adopts and adds hot melt material heating and melting, under the control of computer, the material of thawing is sprayed from shower nozzle, profile according to cross section, by material selectivity be coated on workbench, cooling vent forms a layer cross section fast, after one formable layer completes, workbench descends or improves a height, one deck under reshaping, until form whole solid modelling, because may there be the problem of thickness inequality in the thermo-fuse print adopted, easily occur that in the time of three printer work blocking silk takes turns the moving problem of skidding, thereby caused from the thermo-fuse diameter of shower nozzle ejection inhomogeneous, affect printing precision and quality.
Summary of the invention
the purpose of this invention is to provide a kind of three-dimensional printer that the silk wheel is difficult for skidding that blocks.
for achieving the above object, the technical solution used in the present invention is: a kind of three-dimensional printer of synchronous wire feed, it comprises frame, be arranged on the printing mechanism on frame, described printing mechanism comprises the mount pad be arranged on described frame, be arranged on the servomotor on mount pad, card silk wheels by described driven by servomotor, be arranged on the passage of the importing thermo-fuse of described card silk wheels below, described card silk wheels comprise the first card silk wheel and the second card silk wheel, described passage bottom is provided with orifice of spinneret, the arrival end of described passage be arranged on that described the first card silk wheel and the second card silk take turns under, described passage bottom is provided with heater, described card silk wheels also comprise the synchronous transmission device of described driven by servomotor, synchronous described the first card silk wheel and the second card silk wheel of driving of described synchronous transmission device.
preferably, described synchronous transmission device comprises the follower that takes motor-driven driving wheel, drives by described driving wheel transmission by described private, described driving wheel and described the first card silk coaxial connection of wheel, described follower and described the second card silk coaxial connection of wheel.
further preferably, on described frame, also be provided with along the slide block with the crossing linear slide of vertical, described the second card silk wheel rotates and is arranged on described slide block, is provided with on described slide block and promotes the elastic component of described slide block to the direction motion of described the first card silk wheel.
further preferably, be provided with the gathering sill that horizontal direction is extended on described mount pad, described slide block is arranged in the gathering sill on described mount pad.
further preferably, described driving wheel and described follower are the ladder type gear that pressure angle is 14 degree-15 degree.
because technique scheme is used, the present invention compared with prior art has following advantages:
because the present invention has adopted synchronous driving wheel, can make the card silk wheel synchronous rolling of the right and left, increased wire feed thrust, the assurance wire feed is reliable, adopt elastic component that thermo-fuse is compressed simultaneously, further reduced the possibility that thermo-fuse skids, improved three-dimensional printer and printed reliability.

The specific embodiment
below in conjunction with embodiment shown in the drawings, the invention will be further described:
embodiment mono-: referring to the three-dimensional printer of a kind of synchronous wire feed shown in accompanying drawing 1-4, it comprises the frame (not shown), be arranged on the printing mechanism on frame, printing mechanism comprises the mount pad (1) be arranged on frame, be arranged on the servomotor 2 on mount pad 1, the card silk wheels that drive by servomotor 2, be arranged on the passage 3 of the importing thermo-fuse of card silk wheels below, passage 3 bottoms are provided with orifice of spinneret 4, the arrival end of passage 3 be arranged on card silk wheels under, passage 3 bottoms are provided with heater 5, card silk wheels comprise first card silk wheel the 7 and second card silk wheel 8, card silk wheels also comprise the synchronous transmission device 6 of driven by servomotor, synchronous first card silk wheel the 7 and second card silk wheel 8 that drives of synchronous transmission device 6, by synchronous driving first card silk wheel the 7 and second card silk wheel 8, can effectively improve the possibility of wire feed.
synchronous transmission device 6 comprises the driving wheel 61 by driven by servomotor, the follower 62 driven by driving wheel 61 transmissions, driving wheel 61 coaxially is connected with the first card silk wheel 7, follower 62 coaxially is connected with the second card silk wheel 8, on frame, also be provided with along the slide block 10 with the crossing linear slide of vertical, the second card silk wheel 8 rotates and is arranged on slide block 10, be provided with on slide block 10 and promote the elastic component 11 of slide block 10 to the direction motion of the first card silk wheel 7, be provided with the gathering sill that horizontal direction is extended on mount pad, slide block 10 is arranged in the gathering sill on mount pad 1, compress first card silk wheel the 7 and second card silk wheel 8 and middle thermo-fuse thereof by elastic component 11, can meet the demand of different-diameter thermo-fuse, can prevent that again thermo-fuse from skidding in first card silk wheel the 7 and second card silk wheel 8.
driving wheel 61 is the ladder type tooth with the flute profile of follower 62, because the axle of the first card silk wheel 7 and follower 62 is arranged on slide block 10, can produce along with slide block 10 minute movement, driving wheel 61 adopts the ladder type tooth with follower 62, can effectively reduce the impact that between driving wheel 61 and follower 62, variable in distance is brought.
embodiment bis-: its content and embodiment mono-are basic identical, and difference is that synchronous transmission device 6 comprises the follower 62 that the combination of the driving wheel 61 by driven by servomotor, the gear train driven by driving wheel 61 or gear and belt wheel, the above-mentioned combination transmission by gear train or gear and belt wheel drive.
above-described embodiment is only explanation technical conceive of the present invention and characteristics, and its purpose is to allow the person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
