The screw thread to match is formed in 2 external wall of upper portion of conveying pipeline, outside lower 3 lower inner diameter of conveying pipeline and 4 top of discharge head
Diameter is identical, in lower 3 lower inner wall of conveying pipeline and is formed with the screw thread to match in 4 external wall of upper portion of discharge head, described
Upper 2 lower inner diameter of conveying pipeline is identical as the lower 3 top outer diameter of conveying pipeline, and the upper 2 lower part outer wall of conveying pipeline is formed with sealing
Circle 23, rubber can be selected in material, is slidably connected between gone up conveying pipeline 2 and lower conveying pipeline 3 and keeps sealing, the upper conveying pipeline
2 bottoms are equipped with the first check valve 21；The motor 5 keeps opposing stationary with the upper conveying pipeline 2, the motor 5 can be pacified
On the upper conveying pipeline 2, the motor 5 and upper conveying pipeline 2 can also be mounted in the same rack of 3D printer with
Keep opposing stationary, the rack gear 7 is set to lower 3 outer wall of conveying pipeline, and 7 left and right ends of rack gear are formed with baffle and (do not mark
Show), the gear 6 is connected with 5 output end of motor, and the gear 6 is nibbled between the baffle and with 7 phase of rack gear
It closes.
In the present embodiment, 2 outer wall of upper conveying pipeline extends downwardly after extending horizontally outward, is formed and installs the motor
Mounting plate 22, the motor 5 is installed on the mounting plate 22.Second one-way valve 41 is equipped at the top of the discharge head 4, it can be with
