Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing equipment, and more specifically, to an automatic sheet metal stacking and sorting mechanism. Background Art

[0002] At present, the produced metal sheets or processed products often have a process of stacking, bundling and external packaging storage. Especially for galvanized steel sheets and some aluminum alloy sheets or processed products during stacking and storage, especially during outdoor stacking and storage, due to the friction that occurs when the sheets are stacked, and because there are impurities on the surface of the sheets, the sheets will be worn. Moreover, there are always small gaps when the sheets are stacked, and "crevice corrosion" is likely to occur under certain conditions, especially when the humidity is high, the temperature difference is large, and the ventilation is poor. Once "condensation" occurs, corrosion is more likely to occur, thus affecting the quality of the sheets or products. At the same time, the uneven stacking of the sheets during the stacking process will cause trouble in the later extraction process. Summary of the Utility Model
