The utility model discloses a set up first gear, second gear, third gear and fourth gear, driving motor effectual moment of torsion that has increased under the combined action of first gear, second gear, third gear and fourth gear has reduced the requirement to driving motor power like this, has realized the drive ratio of specific progression, has promoted the stability of 3D print head subassembly, has improved the printing precision, uses more portably.
Description
Technical field
The utility model relates to printing technique field, particularly relates to a kind of 3D and prints drives structure.
Background technology
3D printer is also known as three-dimensional printer, a kind of accumulation manufacturing technology, i.e. a kind of machine of RP technique, it is based on a kind of mathematical model file, use special wax material, powdery metal or plastics etc. can jointing material, manufacture three-dimensional object by the jointing material printed from level to level.Present stage, three-dimensional printer was used to manufacture a product.The mode successively printed carrys out the technology of constructed object.The principle of 3D printer is that data and raw material are put in 3D printer, and machine can be created product from level to level according to program.
The form of the stacking thin layer of 3D printer has varied.3D printer and the maximum difference of conventional printer are that " ink " that it uses is out and out raw material, and the form of stacking thin layer has varied, can be used for the medium wide variety printed, from various plastics to metal, pottery and rubber-like material.Some printer can also in conjunction with different medium, makes that one, the object printed is hard and other end is soft.
Also can print food by 3D printer, be the developing direction in 3D printer future.Drive in existing 3D printer that the motor size of nozzle component wire feeding gear is large, Heavy Weight, make nozzle component poor stability in moving process on the one hand, easy generation is shivered phenomena impair printing precision, large-sized motor occupies larger space on the other hand, has tied up the useful space that 3D prints.In order to improve this phenomenon, a lot of novel 3D printer starts to attempt using small size motor, but this results in another one problem, and the torsion being exactly small size motor is not enough, cannot meet needed for nozzle component driving.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of 3D and prints drives structure.
The utility model is achieved through the following technical solutions:
A kind of 3D prints drives structure, comprise drive motors, described drive motors side is connected with fixed cover, described fixed cover is circumferentially provided with several fixing holes, described drive motors output is connected with the first gear, described first gear is meshed with the second gear, described first gear diameter is less than the second gear diameter, described second gear is connected with the 3rd gear, described second gear diameter is greater than the 3rd gear diameter, described 3rd gear is meshed with the 4th gear, and described 4th gear is provided with power transmission shaft.
As optimal technical scheme of the present utility model, for key is connected between described drive motors with the first gear.
As optimal technical scheme of the present utility model, described first Gear axis and the second Gear axis are arranged in parallel.
As optimal technical scheme of the present utility model, described second Gear axis and the 3rd Gear axis conllinear.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model is by arranging the first gear, the second gear, the 3rd gear and the 4th gear, such drive motors effectively increases moment of torsion under the acting in conjunction of the first gear, the second gear, the 3rd gear and the 4th gear, reduce the requirement to drive motors power, achieve the gearratio of specific progression, improve the stability of 3D printer head assembly, improve printing precision, use easier.
