3D printer is a kind of printing device arising at the historic moment based on 3D printing technique, so-called 3D printer technology is a kind of rapid shaping technique of workpiece, to take the mathematical model file of workpiece to be basis, after using the thermoplastics such as metal or plastics, there is adhesive material, by the mode of successively printing, form the technology of workpiece.3D printer, in print procedure, requires print head above to move arbitrarily at space three axes (X-axis module, Y-axis, Z axis), to tackle the workpiece of different exterior contours.
At present, the Z axis of 3D printer adopts double lead-screw drive mechanism mostly, comprises two turn-screws, and two turn-screws are driven by two motors respectively.But, there is a fatal shortcoming in said structure: when mechanical overload or power-off, two motor rotations are asynchronous, thereby cause two asynchronous rotations of turn-screw, and then cause X-axis module high, phenomenon that another side is low on one side, cause X-axis module not parallel with the table top that print head is housed, finally make 3D printer cannot complete print job, affect printing effect and quality.
In addition, once there is the problem that above-mentioned X-axis module one side is high, another side is low, must user manually to X-axis module, carry out leveling, this is a very professional job, domestic consumer cannot complete, thereby cause the 3D printer of this structure by the librarian use that has certain mechanical major, greatly to retrain the application area of such 3D printer.
Model utility content
The shortcoming of prior art in view of the above, the technical problems to be solved in the utility model is to provide a kind of 3D printer Z axis synchronization transmission structure that can two turn-screw Synchronous Transmission of strict guarantee.
For achieving the above object, the utility model provides a kind of 3D printer Z axis synchronization transmission structure, comprise shell and establish Z axis module in the enclosure, described Z axis module comprises the first turn-screw and second turn-screw of vertical placement, also comprise a drive motor, the lower end of described the first turn-screw is provided with the first synchronizing wheel, the lower end of the second turn-screw is provided with the second synchronizing wheel, the output shaft of described drive motor is provided with the 3rd synchronizing wheel, described the first synchronizing wheel, the second synchronizing wheel, and the 3rd synchronizing wheel be positioned at same plane, and be connected by a Timing Belt.
Further, the two ends of described the first turn-screw and the second turn-screw are equipped with a bearing, and this bearing is fixedly connected with shell.
Preferably, described bearing is fixed on shell by fastening piece.
Preferably, described drive motor is a stepper motor.
The 3D printer Z axis synchronization transmission structure that the utility model relates to has following beneficial effect:
In this 3D printer, can two turn-screw Synchronous Transmission of strict guarantee, thus guarantee that in 3D printer, X-axis module is strictly parallel with table top, and then raising print quality and efficiency.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and coordinate accompanying drawing to be elaborated to this patent.

Embodiment
By particular specific embodiment, mode of execution of the present utility model is described below, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this specification.
Notice, appended graphic the illustrated structure of this specification, ratio, size etc., equal contents in order to coordinate specification to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the utility model, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under the effect that the utility model can produce and the object that can reach, all should still drop on the technology contents that the utility model discloses and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", the term of D score, " left side ", " right side ", " centre " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figure 1, the utility model provides a kind of 3D printer Z axis synchronization transmission structure, comprise shell and establish Z axis module in the enclosure, described Z axis module comprises the first turn-screw 1 and second turn-screw 2 of vertical placement, also comprise a drive motor 3, the lower end of described the first turn-screw 1 is provided with the first synchronizing wheel 4, the lower end of the second turn-screw 2 is provided with the second synchronizing wheel 5, the output shaft of described drive motor 3 is provided with the 3rd synchronizing wheel 6, described the first synchronizing wheel 4, the second synchronizing wheel 5, and the 3rd synchronizing wheel 6 be positioned at same plane, and be connected by a Timing Belt 7.In the present embodiment, described drive motor 3 is a stepper motor, with synchronous the first turn-screw 1 and second turn-screw 2 of driving of mode of stepping.
