[0023] The utility model discloses a metal sheet feeding mechanism, comprising a frame 1, a movable lifting seat 2, a mobile platform 3, an adsorption device 4, an air blowing device 5 and a feeding device 6. The movable lifting seat 2 moves the metal sheet material to the bottom of the mobile platform 3. According to the shape and size of the metal sheet, the positions of the adsorption device 4, the air blowing device 5 and the feeding device 6 are adjusted by the mobile platform 3. The adsorption device 4 sucks up the metal sheet on the top layer. Due to the tension between adjacent metal sheets, multiple metal sheets can be easily stacked and brought up synchronously.
