It has a wide range of applications and can effectively reduce the workload of staff and improve processing production efficiency.

[0027] Preferably, the rotary drive assembly 3012 includes a rotary drive motor 4, a rotating shaft 5 and a slewing bearing 6. The turntable 3011 is arranged on the slewing bearing 6 and is circumferentially fixedly connected to the rotating shaft 5. The rotary drive motor 4 drives the rotating shaft 5 to rotate and drives the turntable 3011 to rotate.

[0028] Preferably, a hollow support rod 7 is provided at the axis of the rotating shaft 5 and the rotating disk 3011, the lower end of the hollow support rod 7 is fixedly connected to the rotating drive motor 4, and the upper end of the hollow support rod 7 is provided with a material sensing switch 8 for detecting the arrival of materials. In this embodiment, the hollow support rod 7 passes through the axis of the rotating shaft 5 and the turntable 3011, and the hollow support rod 7 and the material sensing switch 8 thereon do not rotate on the frame 1.
