[0039] The filling principle of this application is as follows:

[0040] Step 1: The rotary valve 516 is rotated to connect the feed port and the end of the filling injection piston 513, and the filling injection piston 513 is pulled rightward with a set stroke, so that the filling is sucked into the filling channel of the rotary valve 516 from the feed port;

[0041] Step 2: Rotate the rotary valve 516 90 degrees to connect one end of the filling piston 513 with the end of the filling inlet pipe 517;

[0042] Step 3: The filling piston 513 is pressed to the left by a set stroke, so that the fillings within a certain weight range enter the filling tube 510 along the filling feeding tube 517;

[0045] Step 6: The filling tube 510 returns to the set position;

[0046] Step 7: Push the stuffing tube 505 back to the set position;

[0047] Step 8: The rotary valve 516 returns to the set position;
