[0066] Example 2

[0067] The structure of this embodiment is basically the same as that of the first embodiment. The difference is that a transfer mechanism is arranged between the side of the workbench 1 near the drying assembly and the return platform 101, and the transfer mechanism includes a fixed assembly 5 and a rotating assembly 6. The fixed assembly 5 is located above the workbench 1 and outside the drying chamber 3, and the rotating assembly 6 is arranged between the workbench 1 and the return platform 101, and one end of the fixed assembly 5 is correspondingly connected with the rotating assembly 6.
