5. The automatic counting and feeding method of metal materials according to claim 4, characterized in that: all the feeding magnets are distributed on the first circumference; the center of the first circle is positioned on the rotating shaft of the magnetic disk body of the feeding mechanism.
6. The automatic counting and feeding method of metal materials according to claim 3, characterized in that: the middle partition plate gradually inclines downwards when extending from one end far away from the conveying unit to one end close to the conveying unit.
7. The automatic counting and feeding method of the metal materials according to claim 3, characterized in that: and a coaming plate is arranged on the outer side of the feeding opening of the middle partition plate.
8. The automatic counting and feeding method of metal materials according to claim 3, characterized in that: the inside of the hopper is a wedge-shaped space with a wide upper part and a narrow lower part; the bottom of the wedge-shaped space is arc-shaped.
9. The automatic counting and feeding method of metal materials according to any one of claims 1 to 8, characterized in that: the counting module is arranged at the front end of the front-most conveying unit to automatically detect the feeding quantity of the metal materials; conveying the metal materials by each level of conveying units until the feeding quantity of the metal materials detected by the counting module is equal to the target feeding quantity; when the metal material feeding quantity is equal to the feeding target quantity, all levels of conveying units stop working, the metal material feeding quantity detected by the counting module is reset, and the setting of the next feeding target quantity is waited.
10. The automatic counting and feeding method of metal materials according to any one of claims 1 to 8, characterized in that: a storage chute for temporarily storing the metal materials is arranged between the hopper and the conveying channel; when the quantity of the metal materials in the material storage chute is less than the set material storage quantity, the feeding mechanism and the stirring mechanism are started to work; and when the quantity of the metal materials in the material storage chute is larger than or equal to the set material storage quantity, the feeding mechanism and the stirring mechanism stop working.
