[0039] The rotating assembly includes a rotating frame 624 and a receiving slot 625. The rotating frame 624 is rotatably mounted on the mounting frame 2. A plurality of receiving slots 625 are provided on the rotating frame 624. The plurality of receiving slots 625 are evenly distributed at equal intervals on the rotating frame 624. The lengths of the rotating frames 624 on both sides of the receiving slots 625 are different.

[0040] The transmission assembly includes a transmission disk 621, a protrusion 622 and an arc-shaped groove 623. One side of the receiving groove 625 is fixedly connected to the middle of the transmission disk 621, and the rotation center axis of the receiving groove 625 coincides with the center line of the transmission disk 621; a plurality of protrusions 622 are fixedly mounted on the transmission disk 621, and the plurality of protrusions 622 are evenly distributed on the transmission disk 621 at equal intervals; the protrusion 622 abuts against the block 613, and the protrusion 622 is fitted and slidably connected with the groove 614; an arc-shaped groove 623 is provided on the outer side of the protrusion 622, and the arc-shaped groove 623 is fitted and slidably connected with the rotating disk 612;

The rotating frame 624 on the lower side of the receiving groove 625 at the feeding end is a supporting block, and the rotating frame 624 on the upper side is a limiting block. Similarly, the rotating frame 624 on the lower side of the receiving groove 625 at the discharging end is a supporting block, and the rotating frame 624 on the upper side is a limiting block. The length of the supporting block at the feeding end is greater than the length of the limiting block, and the length of the supporting block at the discharging end is less than the length of the limiting block. This makes feeding and discharging more convenient.
