This invention can improve the security of VPN transmission.

This utility model relates to the field of sheet metal production technology, and more particularly to a sheet metal material unloading and conveying mechanism for a sheet metal material warehouse. It includes a conveyor table equipped with a conveyor belt, and the conveyor table is respectively equipped with a limiting mechanism for conveying a stable layer of sheet metal and a cleaning mechanism for removing debris from the surface of the conveyor belt. By setting the limiting mechanism, this utility model can limit the sides of the sheet metal during conveying, preventing conveying deviation and improving the stability of the sheet metal conveying. Furthermore, the buffer structure reduces collisions with the sheet metal, thereby improving the safety of sheet metal conveying. By setting the cleaning mechanism, debris adhering to the surface of the conveyor belt can be removed simultaneously during the conveying of the sheet metal, preventing debris from scratching the sheet metal surface and affecting the production quality. The removed debris can also be collected, demonstrating practical performance.
