Fecha de publicación: 19/02/2021 Fuente: Wipo Tobacco Agriculture The utility model discloses an opening and closing type tobacco leaf sorting device which comprises a machine frame, a plurality of adsorption type feeding mechanisms used for product conveying are arranged on the machine frame in series, a gap used for product discharging is formed between every two adjacent pairs of adsorption type feeding mechanisms, and an opening and closing mechanism is arranged at the tail end of each adsorption type feeding mechanism. The opening and closing mechanism is parallel to the embedding gap or the opening gap of the adsorption type feeding mechanism and usedfor feeding or discharging products, the discharging action of the products is completed through cooperation of the gap and the opening and closing mechanism, the opening and closing mechanism is independent of the adsorption type feeding mechanism, the action of the opening and closing mechanism does not affect the feeding efficiency of the adsorption type feeding mechanism, and the feeding efficiency of the adsorption type feeding mechanism is improved. And the sorting efficiency of the whole device can be improved.
