As preferably, described motor is stepper motor.
As preferably, the gear ratio of described first gear and the second gear is 2: 1.
Further, described rotating disk comprises upper shell, the lower house be connected with this upper shell, and is arranged in upper shell, for feed pipe being limited to the fixture in upper shell.
Again further, the retaining washer for being limited to by tube connector in this discharging opening is also provided with in described discharging opening.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model reasonable in design, the lifting of its Z axis have employed umbrella pinion and drives the positive drive mode of screw mandrel to drive printing mechanism to move, have and move the advantage steady, transmission is effective, sync rates is high, and the utility model can also adjust the rate of climb of screw mandrel by the gear ratio designing the first gear and the second gear, thus not only ensure that the stationarity of lifting platform well, and optimize the effect of printing.
(2) the utility model is by arranging rotating disk and multiple shower nozzle not of uniform size, when needing to carry out squeezing spray to different positions, only rotating disk need be rotated, select the shower nozzle of corresponding size, crowded spray work can be carried out, and then not only save material well, and effectively improve the shaping precision of finished product.
