After the feeding is completed, the rotary platform 44 can be rotated again to return to its original position while the raw material tank 1 is turned back to the state of opening upward again. At the same time, the first moving platform 42 can move forward along the rail 41, the second moving platform 45 also moves forward along with the first moving platform 42, so that the material box 1 which is completely charged is taken out of the smelting furnace 7 by the lifting and charging assembly 43, and then the second moving platform 45 can move leftward along the slide rail 421 to be directly above the charged position 212.

Then, the swing frame 4341 is contracted by the hydraulic cylinder mechanism, so that the swing frame 4341 swings downwards in a vertical plane vertical to the ground, the downward swing of the swing frame 4341 is converted into the downward translation of the feeding rod turnover mechanism 432, and therefore, the feeding rod 4321 can drive the raw material box 1 to translate downwards and place the raw material box 1 which is fed to the fed position 212. Then the lifting mechanism 22 drives the placing platform 21 to move from the second position to the first position, in the process, the rotating mechanism 23 drives the placing platform 21 to rotate 90 degrees in the horizontal plane, so that the removing device 2121 on the placing platform 21 and the transferring device 3 are arranged side by side and opposite to each other, and the receiving frame 2111 and the output end of the input device 5 are arranged side by side and opposite to each other, at this time, the removing device 2121 and the transferring device 3 can convey the raw material box 1 to the output device 6, and the input device 5 can convey the raw material box 1 filled with raw material to the receiving frame 2111. Thus, the automatic feeding system 100 completes one complete charging, feeding and return of the raw material tank 1.

Further, the automatic feeding system 100 may automatically repeat the above process. In the two adjacent charging processes, in the process that the feeding rod 4321 at the next time is connected with the raw material tank 1 and is operated by the swinging mechanism 434 and the feeding rod overturning mechanism 432 together to feed the raw material tank 1 into the smelting furnace 7 for charging, the raw material tank 1 which has been charged at the previous time and the placing platform 21 move from the second position to the first position along with the lifting mechanism 22 to prepare for the next charging, charging and other operations.
