The materials between the feeding baffles 18 will fall into the vacuum melting furnace through the unloading mechanism, and the materials are continuously supplied. When the materials in the feeding bin 1 are used up, the feeding mechanism will start, and the materials in the storage bin 3 will be slid into the feeding bin 1 to ensure the continuous addition of materials.

When the material is added, the first motor 5 reverses, thereby causing the inclined sealing plate 9 to descend, and then seals the feeding bin 1, so that when adding material to the storage bin 3, the sealing environment of the feeding bin 1 will not be affected, and when material needs to be added to the storage bin 3, the sealing device can be opened to add material, and after the addition is completed, the sealing device can be closed to seal the storage bin 3, while ensuring the sealing environment of the storage bin 3, thereby improving work efficiency, being simple and practical.
