[0018] Specifically, any supporting and positioning structure is respectively composed of a roller, and any of the rollers is arranged on the housing 1 by being arranged on a wheel axle, the wheel axle is parallel to the axial direction of the roller disc 2, and the roller is tangent to the roller disc 2.

The tail of the screw is placed in the conveying groove, and the head of the screw is located on the upper side of the conveying groove. The screw conveying guide rail can drive the screw to move.

[0021] The working principle of this embodiment:

[0022] During operation, the linear vibrator, the first drive mechanism, and the second drive mechanism operate simultaneously. The first motor 6 drives the roller disc 2 and the loading plate 4 to rotate through the first gear 7 and the second gear 8. The second motor 9 drives the swing plate 5 to swing above the screw conveying guide rail through the connecting rod 10, the swing rod 11, and the swing shaft 12. A number of screws are placed in the housing 1. Under the vibration of the linear vibrator, the screws move toward the inner cavity of the roller disc 2. When the loading plate 4 passes the bottom of the housing 1, it drives a number of screws to rise. When the loading plate 4 passes the top of the housing 1, it is in a vertical state. The screws slide down to the screw conveying guide rail by gravity. Some of the screws are inserted into the conveying groove of the screw conveying guide rail, and the material is successfully loaded. The screw conveying guide rail conveys this part of the screws to the subsequent production line. The other part of the screws are not successfully inserted into the conveying groove. The screws that are not successfully loaded are swept down to the bottom of the housing 1 by the repeatedly swinging swing plate 5, and then move to the concave cavity 3 through the linear vibrator, and the above-mentioned loading action is repeated.

[0023] The utility model provides a screw feeding mechanism with simple structure and convenient operation. It utilizes a linear vibrator and a roller plate 2 to drive the screw feeding and utilizes a swing plate 5 for screening, thereby replacing manual screw feeding, improving production efficiency, and being suitable for automated production lines.
