[0002] The multi-rotation station screw feeding mechanism is a supporting device for sorting and conveying screws. When feeding screws, direct conveying can easily cause confusion, and the screws need to be sorted and then fed in sequence. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of the multi-rotation station screw feeding mechanism.

[0003] The existing screw feeding mechanism has certain drawbacks when in use. First of all, when in use, the existing screw feeding mechanism has a relatively simple structure, and the material is directly transported by a vibration plate. The screws after transportation are prone to confusion, which is not conducive to people's use. In addition, the degree of automation in the transportation process is low, which brings certain adverse effects to the actual use process. For this reason, we propose a free-fall multi-rotation station screw feeding mechanism. Utility Model Content
