[0048] The transfer and feeding mechanism 6 of the present invention has a simple structure and low cost. After the picking component 631 picks up the material, the self-rotation driving component 64 drives the swing arm 62 to swing and rotate the material from the discharge port 61 along the vertical plane to a certain angle to turn the vertically placed material into a horizontal state. At the same time, the self-rotation driving component 64 drives the self-rotation holding component 63 to rotate to rotate the material to a certain angle, thereby completing the swinging and rotating feeding actions.

The other end of the rocker 642 moves along the uneven surface of the cam 641, and one end of the rocker 642 drives the second gear 643 to rotate, and the second gear 643 drives the material picking component 631 to rotate through the first gear 632 to realize the material rotation.

[0050] Specifically, the transfer and feeding mechanism 6 of the present invention, the swing driving assembly includes a power source and a pulley assembly 66, and the power source drives one end of the swing arm 62 to rotate relative to the base 60 through the pulley assembly 66.
