The overall structure is light, the moving parts are streamlined, the rotation process is smooth and continuous, and there is almost no impact on the overall mechanism, thereby improving the blanking accuracy and the service life of components.

[0040] The specific working process of the rotating device is that the rotating device cooperates with the receiving and unloading work of the transfer part 43, combined with Figure 4 and Figure 5 When the mechanism changes from the loading state to the transfer state, the rotating device drives the transfer part 43 to rotate; combined Figure 7 As shown, the first driving member 62 drives the second gear 63 to rotate, the second gear 63 meshes with the second rack 66, so that the second rack 66 and the moving plate 64 move along the first direction, the first rack 65 is fixed to the moving plate 64, so that the first rack 65 moves synchronously along the first direction, the first rack 65 meshes with the first gear 61, the first gear 61 and the transfer part 43 are coaxially fixed, so that the first gear 61 and the transfer part 43 rotate along the axis, the transfer chamber 44 changes from opening downward to opening upward, the first driving member 62 stops, the transfer part 43 stops rotating, the mechanism completes the conversion from the loading state to the transfer state, and the material 10 falls from the metering chamber 5 into the transfer chamber 44; combined with Figure 5 and Figure 6 When the mechanism changes from the transfer state to the unloading state, the working process of the rotating device is similar to the above process and will not be repeated here.
