The working principle of the material packaging machine is as follows: step S1, before the system is started, manually rotating a first hand wheel to adjust the bag clamping width, manually rotating a second hand wheel to adjust the bag embracing width, when the system is positioned at an initial position, the bag pulling cylinder and the bag pulling limiting cylinder are in a contraction state, the bag clamping pneumatic finger is in an opening state, and the bag embracing cylinder piston rod is in a contraction state; the filling initial state is that the clamping pneumatic fingers are in an open state, the first clamping limiting cylinder is in an extending state, the second clamping limiting cylinder is in an extending state, the filling cylinder is closed, the lifting cylinder contracts to enable the filling opening mounting seat to be in a rising in-place state, and one side face of the clamping finger mounting plate is attached to one side face of a limiting plate of the second clamping limiting cylinder; step S2, when the material bag is bagged to the filling cylinder, the clamping pneumatic fingers on the two sides of the material bag clamp the bag opening, the filling cylinder opens the bag opening of the material bag to carry out charging, and meanwhile, the clamping finger mounting plates are driven by the material bag to approach the filling cylinder due to the opened material bag until the clamping finger mounting plates are contacted with a limiting plate of a first clamping limiting cylinder, the bag opening of the material bag is loosened, and the bag opening is prevented from being expanded and deformed by the filling cylinder; after filling, the lifting cylinder extends downwards, and the material bag filling and clamping mechanism descends to a certain position; step S3: the material bag moving clamp clamps the filled material bag, clamping pneumatic fingers are loosened, a filling barrel is closed, a lifting cylinder contracts to reset a filling part, the material bag moving clamp conveys the filled material bag away, a first clamping limiting cylinder contracts to enable one side surface of a clamping finger mounting plate to be attached to one side surface of a limiting plate of a second clamping limiting cylinder, the first clamping limiting cylinder extends out after the first clamping limiting cylinder is attached to the side surface of the limiting plate of the second clamping limiting cylinder, and then the system repeats the process;
