The utility model relates to the technical field of staggered feeding, and discloses a bowl-shaped plug staggered feeding mechanism which comprises two containing plates, a stock bin and a bottom plate, two sliding grooves are formed in the side walls of the containing plates, a containing groove is formed in the top of each containing plate, a disc is arranged in each containing groove, two limiting grooves are formed in each disc, and the limiting grooves are arranged in the containing grooves. And sliding columns are slidably connected to the inner walls of the two limiting grooves correspondingly, connecting plates are fixedly connected to the top ends of the two sliding columns correspondingly, arc-shaped clamping plates are fixedly connected to the tops of the two connecting plates correspondingly, and a rotating rod is fixedly connected to the bottom of the disc. According to the bowl-shaped plug conveying device, the first motor is started, the sliding column drives the two connecting plates to move, opening and closing movement of the two arc-shaped clamping plates is achieved, when the arc-shaped clamping plates move in the opposite direction, the bowl-shaped plug is clamped and fixed, it is guaranteed that the bowl-shaped plug does not deviate in the conveying process, and when the arc-shaped clamping plates move in the back direction, the bowl-shaped plug can be easily loosened, and the feeding link is completed.
