[0054] The first supporting member 346 and the second supporting member 356 are provided with L-shaped guide structures. The first supporting member 346 has the same function as the second supporting member 356. Taking the first supporting member as an example, there are four first supporting members 346 at one end of the large box 90, two on the left and two on the right. The two first supporting members on the left are installed on the first vertical clamping cylinder 345 on the left, and the two first supporting members on the right are installed on the first vertical clamping cylinder on the right. Under the pushing of the small box pushing cylinder 311, the small box 91 enters one end of the large box 90 along the four first supporting members 346, and the four first supporting members are located at the four corners of the small box, guiding the small box into the large box and ensuring the smooth entry of the small box into the large box.

Under the drive of the tray transfer vertical cylinder 132, the tray lifting frame 133 is lifted to lift the empty tray from the feeding track 11. Under the drive of the tray transfer horizontal cylinder 131, the tray lifting frame 133 and the empty tray thereon reach one end of the tray unloading track 12. Then, the tray lifting frame 133 is lowered, and the empty tray falls on the tray unloading track 12, which transports the empty tray to the tray recycling station.
