The circular material frame 32 is uniformly and spacedly arranged on the rotating disc 34, and the plurality of circular material frames 32 are fixedly connected with the rotating disc 34 to realize synchronous rotation. In the preferred embodiment, the circular material frame 32 is provided with four, when one of the circular material frames 32 is located at the discharging end of the conveyor 4, one of the circular material frames 32 is located at the side close to the conveying mechanism 5, and two of the circular material frames 32 are located on the same diameter line of the rotating disc 34. Further, one of the circular material frames 32 receives the disc on the conveyor 4 on one side; the pushing assembly 11 pushes the discs in the circular material frame 32 close to the conveying mechanism 5 out one by one to make the discs conveyed to the concave forming mechanism 2 through the conveying mechanism 5.

[0025] Wherein, the circular material frame 32 is formed by a plurality of vertical columns spaced circumferentially, and a plurality of vertical columns are externally sleeved and welded with an iron ring, thereby improving the stability of the circular material frame 32. The top of each vertical column is outwardly bent and extended, so that the opening at the top of the circular material frame 32 is larger, facilitating the disc to fall into the circular material frame 32. The space between the two adjacent vertical columns is a visual window, so that the stacking condition of the discs in the circular material frame 32 can be directly observed through the visual window.

[0026] Referring to Figure 1 With Figure 2 , the base 1 is provided with a detection camera 6 facing the visual window, and the detection camera 6 is suitable for detecting whether the two adjacent discs are flatly stacked.
