Example Embodiment

[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.

[0069] The rotating assembly 6 includes a first fixing frame 601 and a second fixing frame 602, and both ends of the first fixing frame 601 and the second fixing frame 602 are fixedly connected with the side edges of the workbench 1 and the return platform 101, respectively. A rotating shaft 603 is rotatably connected between the first fixing frame 601 and the second fixing frame 602, and the included angle formed between the rotating shaft 603 and the side edges of the workbench 1 is 45. Equal to the angle between the rotating shaft 603 and the side of the return table 101, the rotating shaft 603 is fixed with a first gear 606, the second gear is meshed with a second gear, the second gear is connected with a motor, and the motor is fixedly connected with the second fixed frame 602. A rotating frame 604 is fixed on the rotating shaft 603, one of the side bars of the rotating frame 604 is parallel to the side of the table 1, and a chute 605 is provided. The first clamping plate 501 is fixedly connected with the rotating frame 604, the ends of the second clamping plate 502 are slidably connected with the sliding chute 605, and sliding plates 506 are fixed on the second clamping plate 502 at positions corresponding to two sides of the side bar, and the side bar is slidably connected between the two sliding plates 506.
[0070] The first fixing frame 601 is vertical to the rotating shaft 603, the middle of the second fixing frame 602 is vertical to the rotating shaft 603, and the two outer sections are vertical to the side walls of the return table 101 and the workbench 1, respectively.
