Abstract
A kind of silk material extrusion device of 3D printer, comprise drive motors, support, pinion unit unify silk material hold down gag, described gear train assembly comprises driving gear, two driven gears and wire feeding axis, described driving gear connects drive motors, and drive the equidirectional rotation of driven gear simultaneously, described driven gear connects wire feeding axis, compresses silk material between described wire feeding axis and described silk material hold down gag.The utility model is a kind of silk material extrusion device having the 3D printer enough transmitting power and frictional force.
Description
Technical field
The utility model relates to 3D printer field, particularly relates to the extrusion device field of 3D printer.
Background technology
Hot melt lamination rapid shaping technique is the desktop level 3D printing technique of current main flow, which utilizes thermoplastic characteristic, and mainly using acrylonitrile-butadiene-styrene (ABS) (ABS) to be main engineering plastics is consumptive material.What the hot melt basic unit technology of existing main flow adopted is Wei Deshi gear extruder structure, fixed block locks, simultaneously the problem caused enough onward impulses can not be provided to cause, into the problem of silk skidding, wire drawing, have impact on again the precision manufacturing finished product and any surface finish performance to charging.
The wire feeder ubiquity frictional force not foot phenomenon of common wire feed rolls and bearing fit, is difficult to when skidding appears in silk material automatically adjust reparation.
Summary of the invention:
The technical problem that the utility model solves is to provide a kind of silk material extrusion device having the 3D printer enough transmitting power and frictional force.
A kind of silk material extrusion device of 3D printer, comprise drive motors, support, pinion unit unify silk material hold down gag, described gear train assembly comprises driving gear, more than one driven gear and wire feeding axis, described driving gear connects drive motors, and drive driven gear, described driven gear connects wire feeding axis, compresses silk material between described wire feeding axis and described silk material hold down gag.
As preferably, described driven gear is two, and described driving gear drives two driven gears simultaneously, and driven gear rotation direction is identical, and described wire feeding axis is fixed on driven gear axle center.
As preferably, described silk material hold down gag, comprise protrude downwards on both sides lower lock block, press down bolt and holder, the described bolt that presses down is through lower lock block, and lower end connection fixing base, protruding parts, described lower lock block both sides contacts connection two elasticity respectively and presses down parts, and described elasticity presses down parts and wire feeding axis clamps silk material.
As preferably, described elasticity presses down parts and comprises moving runner, and connect the lever in runner axle center, described lever end thereof contacts connects described lower lock block, other end contact connection fixing base.
As preferably, be provided with into a passage below described silk material hold down gag, wire feeding axis is horizontally through into a passage.
The beneficial effects of the utility model are:
1, this silk material extrusion device drives two driven gears to move by driving gear simultaneously, the wire feeding axis connected with two driven gears adds transmission power compared with driving with ordinary gear, due to the synchronous axial system of two driven gears, when skidding appears in a wire feeding axis and silk material, another wire feeding axis can regulate wire feed rate within the shortest time.
2, this expects that two turning cylinders of the silk material hold down gag that the silk material hold down gag of extrusion device coordinates with wire feeding axis compress silk material simultaneously, adds the frictional force of silk material.
Accompanying drawing explanation
Fig. 1 is the front view of the silk material extrusion device of 3D printer;
Fig. 2 is the A-A face sectional view of the silk material extrusion device of 3D printer;
Fig. 3 is the silk material hold down gag structure chart of the silk material extrusion device of 3D printer.
Detailed description of the invention
Fig. 1, Fig. 2 and Fig. 3 are the specific embodiment of the silk material extrusion device of 3D printer, comprise drive motors 2, support 1, pinion unit unify silk material hold down gag 5, gear train assembly comprises driving gear more than 3, one driven gear 4 and wire feeding axis 6, driving gear 3 connects drive motors 2, and drive driven gear 4, driven gear 4 connects wire feeding axis 6, compresses silk material between wire feeding axis 6 and silk material hold down gag 5.
Driven gear 4 is two, and driving gear 3 drives two driven gears 4 simultaneously, and driven gear 4 rotation direction is identical, and wire feeding axis 6 is fixed on driven gear axle center.Stagger before and after two driven gears 4, make two wire feeding axis 6 be in optimum distance.In the present embodiment, wire feeding axis 6 adopts worm screw, the material of wire feeding axis 6 and selecting based on increasing friction force of structure.Can also adopt toothed axle, appearance wears protruding stock, rubber axis etc.
Silk material hold down gag 5 is fixed on support 1, comprise protrude downwards on both sides lower lock block 52, press down bolt 51 and holder 53, press down bolt 51 through lower lock block 52, and lower end connection fixing base 53, protruding parts, lower lock block 52 both sides contacts connection two elasticity respectively and presses down parts, and elasticity presses down parts and wire feeding axis 6 clamps silk material.Elasticity presses down parts and comprises moving runner 56, and connection of rotating takes turns the lever 55 in 56 axle center, and lever 55 end thereof contacts connects described lower lock block 52, other end contact connection fixing base 53.The arm of force distance that wherein lever 55 is connected with holder 53 is less than the arm of force distance be connected with lower lock block projection with lever 55.When lower lock block 52 presses down, drive moving runner 56 to press down by lever 55, this flexible structure is adjustable, and moving runner 56 can rotate along with the rotation of wire feeding axis 6.
Be provided with into a passage 7 below silk material hold down gag 5, wire feeding axis 6 is horizontally through into a passage 7.The moving runner 56 another side contact wire feeding axis 6 of silk material one side contact filament material hold down gag 5.
Above-mentioned explanation is illustrative rather than restrictive.Can recognize that many kinds of the present invention change and distortion by above-mentioned explanation those skilled in the art, it also will drop within the spirit and scope of the invention.
