The frame body is equipped with a blank size-adaptive unified positioning component. This component includes multiple horizontal plates fixedly connected vertically to the inner wall of the frame body. A through groove is formed in the center of the bottom of the frame body, and vertical plates are equidistantly distributed horizontally within the groove. The leftmost vertical plate is fixedly connected to the inner wall of the groove, while the remaining vertical plates are slidably connected to the groove via slide rails. The vertical plates and horizontal plates are slidably inserted into each other, forming multiple blank placement compartments. Using the blank size-adaptive unified positioning component, the multiple vertical and horizontal plates cooperate to form multiple blank placement compartments, allowing multiple rolls of aluminum foil blanks to be annealed to be placed into these compartments respectively.
