When the plate is classified into A type, the baffle of the first baffle turnover mechanism is turned upwards, the plate falls into a A type collecting box on the front lower side of the first baffle turnover mechanism, and the baffle is reset; when the plate is classified into a type B plate, the baffle plate of the second baffle plate turnover mechanism is turned upwards, and the plate falls into a type B collection box on the front lower side of the second baffle plate turnover mechanism; when the plate is divided into the C type, the two baffle turnover mechanisms do not act, and the plate automatically falls into the C type collecting box on the rear lower side of the second baffle turnover mechanism. The work flow is shown in fig. 8.

The above are preferred embodiments of the present invention, and all changes made according to the technical scheme of the present invention that produce functional effects do not exceed the scope of the technical scheme of the present invention belong to the protection scope of the present invention.
