X-axis synchronous belt 324 coordinate, so as to drive printhead 200 to be moved along X-direction.Reduce the drive of X-axis moving mechanism 300 to beat
Print first 200 along X-direction move when driving wheel 322, driven wheel 323 and X-axis synchronous belt 324 between gap, reduce X-axis movement
The transmission deviation of mechanism 300, improves the mobile precision of its control.Y-axis moving mechanism 400 passes through 420 band of the first transmission component
Move two square shafts 410 to rotate, two square shafts 410 rotate so that the second transmission component 430 drives X-axis moving mechanism 300 along Y-axis side
To movement；Moreover, the second synchronizing wheel 431 in the second transmission component 430 and 510 phase of the first screw in Z-axis transmission mechanism
Even, the 3rd synchronizing wheel 432 is connected with the second screw 520 of Z-axis transmission mechanism, so that Z-axis transmission motor drives the first screw 510
When being rotated synchronously with the second screw 520, the second synchronizing wheel 431 and the 3rd synchronizing wheel 432 is driven to be moved along Z-direction.The 3D is beaten
In print machine, Z axis moving mechanism 500 drive Y-axis moving mechanism 400 along Z-direction move when, without driving Y spindle motors 421 to move
It is dynamic, the load of Z axis moving mechanism 500 can be effectively reduced, the mobile precision of its control is improved, ensures that its moving process is steadily suitable
Freely so that printing is more stable.In the 3D printer, y-axis motor 421 and Z axis motor 551 are arranged at the lower section of bottom plate 100,
The top of bottom plate 100 sets screw and square shaft 410, is coordinated by synchronizing wheel and synchronous belt, it can be achieved that controlling printhead 200 along Y-axis
Direction and Z-direction movement so that the space availability ratio of 3D printer is high.
The utility model is illustrated by above-mentioned specific embodiment, it will be appreciated by those skilled in the art that, not
In the case of departing from the scope of the utility model, various conversion and equivalent substitute can also be carried out to the utility model.In addition, it is directed to
Particular condition or concrete condition, can do various modifications, without departing from the scope of the utility model to the utility model.Therefore,
The utility model is not limited to disclosed specific embodiment, and should include falling into the range of the utility model claims
Whole embodiments.
