the feeding mechanism 1 comprises a feeding support 11, a belt conveyor 12, a magnetic plate 13 and a hopper 14, wherein the belt conveyor 12 is fixedly arranged on the feeding support 11, and the magnetic plate 13 is arranged in the belt conveyor 2 and used for supporting a conveying belt of the belt conveyor 12; the magnetic force plate 13 provides magnetic attraction force for adsorbing screws on the conveying belt and conveying the screws through the belt conveying mechanism 12. Specifically, the magnetic plate 13 includes a first support plate 131 obliquely disposed, a second support plate 132 and a third support plate 133 horizontally disposed, and an electromagnet, the first support plate 131 is connected to the second support plate 132, the electromagnet is installed on the back of the first support plate 131 and the back of the second support plate 132, and the third support plate 133 is disposed at the extending position of the second support plate 132; a hopper 14 is provided on the loading ledge 11 and is located at the infeed end of the belt conveyor 12. The hopper 14 is used for storing screws fed by the feeding mechanism 2. In this embodiment, the specific conveying process includes that the screw in the hopper 14 is attracted by the magnetic attraction force of the first supporting plate 131, moves upward along the first supporting plate 131 through the conveying belt, then enters the second supporting plate 132 part, changes the obliquely moving screw into horizontal movement, and finally moves to the third supporting plate 133 part, and the third supporting plate 133 part has no magnetic force, and directly falls down when the screw is conveyed to the end part, and is separated from the belt conveyor 12.
