The automatic feeding apparatus as claimed in claim 2, wherein the bag breaking member further comprises a second blade, a second saw tooth abuttable to the packaging bag, and a second support supporting the second blade, the second saw tooth being formed above the second blade, and the driving member further comprises a second driving portion fixedly connected to one end of the second blade to drive the second blade to reciprocate between the start position and the end position.

4. The automatic charging apparatus of claim 3, wherein the first toothed segment is disposed in an alternating manner with respect to the second toothed segment, and wherein at the alternating position, a first notch and a first link opposite thereto are disposed on the first toothed segment, and a second notch and a second link opposite thereto are disposed on the second toothed segment, and wherein the first link passes through the second notch and the second link passes through the first notch.

5. The automatic charging apparatus of claim 4, wherein the bag breaking member further comprises a protective frame, the protective frame comprising a first bottom cross member and a first top cross member extending along a length direction of the first blade, a second bottom cross member and a second top cross member extending along a length direction of the second blade, a first vertical beam connecting the first bottom cross member and the first top cross member, and a second vertical beam connecting the second bottom cross member and the second top cross member, the first bottom cross member and the second bottom cross member being respectively located below the first blade and the second blade, and the first top cross member and the second top cross member being respectively located below an uppermost end of the first saw tooth and the second saw tooth.

6. The automatic charging apparatus of claim 5, wherein the first notch and the second notch are respectively located at the middle position of the first tooth plate and the second tooth plate.

7. The automatic charging apparatus of claim 3, wherein the first and second racks are disposed parallel to one another.

8. The automatic charging apparatus according to any one of claims 1 to 7, further comprising a bag removing device for removing the broken packaging bag.

9. The automatic feeding apparatus according to claim 8, wherein the bag removing device comprises a fixing bracket, a driving member fixed on the fixing bracket, and an adsorption plate fixed on the fixing bracket for adsorbing the packaging bag, the driving member can drive the adsorption plate to reciprocate between an adsorption position for adsorbing the packaging bag and a release position for releasing the adsorption of the packaging bag.

10. A feeding method of an automatic feeding apparatus for delivering materials into a predetermined container, the automatic feeding apparatus being the automatic feeding apparatus according to any one of claims 1 to 9,

firstly, starting the automatic feeding equipment, wherein the conveying part is positioned at an initial position;

then a first detection unit detects whether a material packaging bag is arranged on the conveying part or not; if not, the conveying part does not act, and if so, the next step is carried out;

the conveying part moves from an initial position to an adsorption position above the conveying part and adsorbs the material packaging bag;

the conveying part conveys the material packaging bag from the adsorption position to a feeding position of the feeding device;

then a second detection unit detects whether the material packaging bag exists at the feeding position, if not, the conveying part returns to the adsorption position from the feeding position, after the material packaging bag is adsorbed again at the adsorption position, the conveying part moves to the feeding position from the adsorption position, and if so, the next step is carried out;

the driving piece drives the bag breaking piece to reciprocate for a preset number of times between the initial position and the final position, and the material packaging bag is broken;

the third detection unit detects whether the delivery of the materials in the material packaging bags is finished, if not, the driving piece drives the bag breaking piece to reciprocate for a preset number of times again to break the material packaging bags, and if so, the next step is carried out;

the carrying section moves to the initial position.
