[0024] Preferably, a guide assembly for improving the movement stability of the drying concave plate 3 is also installed between the first positioning ring 7 and the second positioning ring 8, and the guide assembly includes a plurality of guide rods 10 fixedly installed at the bottom of the first positioning ring 7, and the spring 9 is sleeved on the surface of the guide rod 10. The surface of the second positioning ring 8 is provided with a guide hole 11 corresponding to the guide rod 10, and the surface of the guide rod 10 is slidably connected to the inner wall of the guide hole 11.

[0025] By setting the guide assembly, the stability of the movement of the drying concave plate 3 can be improved. When it vibrates, it will drive the guide rod 10 to slide in the inner cavity of the guide hole 11. In addition, by setting the guide rod 10, it can also play an auxiliary supporting role for the spring 9 to prevent the side bending problem when it is compressed and deformed.
