[0023] Working principle and process:

[0024] When the material pushing action is to be executed, the servo motor 1 receives the signal and rotates, driving the screw rod 3 to rotate through the synchronous wheel 2, and the connecting plate 4 drives the pushing rod 5 to move downward, thereby drawing the filling material into the material cylinder 6; then the piston rod of the cylinder 7 extends out, rotating the valve core of the rotary valve, cutting off the passage between the hopper and the material cylinder, and opening the passage between the filling device and the material cylinder;

[0025] The servo motor 1 reverses and drives the push rod 5 to move upward, pushing the material in the cylinder 6 into the filling device; the piston rod of the cylinder 7 is reset, cutting off the passage between the filling device and the cylinder, and opening the passage between the hopper and the cylinder; the cycle works.

[0026] A pusher device, a rotary valve comprises a valve body 25, a valve core 26, a bearing seat 27, a bearing 28, a bearing cover 29, a bearing ring 30, and a Y-shaped sealing ring 31.
