State Z axis motion fixed mount bottom and be provided with motor B, the Z axis motion fixed mount top is provided with screw mandrel and guide rod, the motor B's
Rotating shaft is fixedly connected by shaft coupling with screw mandrel, and screw rod bushing and leader casing, the screw mandrel are cased with respectively on the screw mandrel and guide rod
Set and leader casing form adapter sleeve after being integrally formed, and slide bar is connected between two adapter sleeves, are provided with the slide bar
Ejecting device, the ejecting device includes shower nozzle and shifter, and the shower nozzle is arranged on the bottom of shifter, the one of the casing
Side is provided with disk of material, and the silk material in the disk of material is through casing top and extends in shower nozzle.
Preferably, the print platform bottom is provided with that two parallel elongated cunnings are convex, and the casing internal bottom is provided with two
The chute that individual cooperation convex with elongated cunning is slided.
Preferably, the both ends that conveyer belt and conveyer belt are provided with the shifter are separately mounted to two adapter sleeves
It is interior.
Preferably, the front and back of the casing communicates with the external world.
Preferably, Z axis motion fixed mount is shaped as Contraband font.
In the utility model, print platform to be moved through chute spacing, solve print platform in moving process
Rock so that printing inaccurate problem;Print platform is only moved in Y direction, and at this moment shower nozzle is more easy to the distance of print platform
Control.
