[0039] The present invention provides a magnesium oxide powder feeding and packaging device. Compared with the prior art, after the magnesium oxide powder is produced, the magnesium oxide powder is fed into the feeding hopper 12 of the feeding platform 11. The magnesium oxide powder in the feeding hopper 12 enters the feeding cylinder 21 through the flexible tube 22 and finally falls into the ton bag. During the continuous feeding of magnesium oxide powder into the ton bag, dust is generated. By activating the dust removal equipment, the dust suction plate 3 can generate suction force to suck the generated dust into the dust removal equipment. Through the above settings, the amount of dust scattered into the air can be reduced during the feeding of powder into the ton bag, thereby reducing the occurrence of dust pollution in the environment.

[0040] It should be noted that before feeding, the ton bag is placed directly below the lifting frame 2, and then the four handles on the ton bag are hung on the four hooks 23 of the lifting frame 2 respectively, so that the feeding cylinder 21 can convey powder into the ton bag; since the feeding cylinder 21 is connected to the discharge port of the feeding hopper 12 through the flexible tube 22, the flexible tube 22 can deform during the up and down movement of the lifting frame 2.
