The first motor 13 drives the rotating roller 11 to rotate, and the rotating roller 11 drives the adjacent rotating roller 11 to rotate through the third conveyor belt 12.

[0038] Refer to Figure 1 and Figure 2 , on the transport rack 2, there are transport rollers 21. There are two transport rollers 21 and they are arranged parallel to each other. A first conveyor belt 22 is sleeved on the transport rollers 21. The transport rollers 21 are connected to the rotating rollers 11 by a fourth conveyor belt 23. The rotating rollers 11 drive the transport rollers 21 to rotate through the fourth conveyor belt 23, and the transport rollers 21 drive the first conveyor belt 22 to rotate.

[0039] Refer to Figure 1 and Figure 2 , on the transfer rack 1, there is a receiving table 3 rotatably installed. On the receiving table 3, there is a receiving member 4. On the transport rack 2, there is a second driving member 5. When the flower rack on the dryer conveyor belt drives the tinplate to rotate and transport to the transfer rack 1, the second driving member 5 drives the receiving table 3 to rotate. At this time, the receiving table 3 is inclined and located above the transfer rack 1. The tinplate fits with the receiving member 4 on one side of the receiving table 3. The second driving member 5 drives the receiving table 3 to rotate in the reverse direction, driving the tinplate to move to the horizontal position. At this time, the rotating rollers 11 and the third conveyor belt 12 transport the tinplate away from the flower rack and are transported by the first conveyor belt 22. When the tinplate is discharged, it is buffered by the receiving member 4 and is not likely to have the problem of being damaged by vibration after directly contacting the rotating rollers 11.
