When the sheet food waiting for stacking reaches the upper part of the front end of the rear conveying mechanism 3, the rear conveying mechanism 3 stops running, so that the sheet food (hereinafter referred to as rear sheet food) is kept right above each rear strip-shaped turning block 46; subsequently, when the next sheet-like food to be stacked is conveyed onto the rear end of the front conveying mechanism 2, the front conveying mechanism 2 is suspended to make the sheet-like food (hereinafter referred to as front sheet-like food) stay right above each front strip-shaped turning block 45; then the first driving motor 41 drives the outer sleeve 43 to rotate, drives each rear strip-shaped turning block 46 to rotate upwards around the axis of the outer sleeve 43, lifts and turns the rear sheet-shaped food forwards at a small angle (the turning angle is generally 20-40 degrees), so that the overlapped surface of the rear sheet-shaped food is inclined towards the front upper part, meanwhile, the second driving motor 42 drives the inner shaft 44 to rotate, drives each front strip-shaped turning block 45 to rotate upwards around the axis of the inner shaft 44, lifts and turns the front sheet-shaped food backwards at a large angle (the turning angle is generally 140 degrees and 160 degrees), so that the overlapped surface of the rear sheet-shaped food is inclined towards the rear lower part, and the front sheet-shaped food and the rear sheet-shaped food are overlapped together in a face-to-face mode through the matching between each front strip-shaped turning block 45 and each rear strip-shaped turning block; then the first driving motor 41 drives the outer sleeve 43 to rotate reversely, drives each rear strip-shaped turning block 46 to rotate reversely around the axis of the outer sleeve 43 and return to the initial state, places two stacked sheet-shaped foods on the front end of the rear conveying mechanism 3, and simultaneously the second driving motor 42 drives the inner shaft 44 to rotate reversely, drives each front strip-shaped turning block 45 to rotate reversely around the axis of the inner shaft 44 and return to the initial state; then the front conveying mechanism 2 and the rear conveying mechanism 3 resume to operate, the front conveying mechanism 2 conveys the next group of sheet-shaped food to be superposed towards the overturning and stacking mechanism 4, and simultaneously the rear conveying mechanism 3 conveys the two superposed sheet-shaped foods to the conveying belt 52; then the group of two laminated food pieces moves from front to back under the driving of the conveyer belt 52 (at this time, the front limit part 57 is not located on the moving path of the group of food pieces, and the conveying of the group of food pieces by the conveyer belt 52 is not affected), until when the group of food pieces crosses the front limit part 57 and reaches the position right below the upper press plate 53, the conveyer belt 52 stops running, the lifting cylinder 541 drives the upper press plate 53 to descend until the upper press plate 53 contacts the group of food pieces, and then the two spindle driving motors 56 respectively drive the corresponding spindles 55 to rotate, which drives the front limit part 57 and the rear limit part 58 to swing together with the group of food pieces, limit the two food pieces in the front-back direction and apply certain force, and at the same time, the two translation cylinders 5101 respectively drive the corresponding side limit parts 59 to translate towards the group of food pieces, the two pieces of food are limited in the left-right direction and are applied with certain acting force, so that the two pieces of food in the superposed state are limited and applied with certain acting force through the conveying belt 52, the upper pressing plate 53, the front limiting part 57, the rear limiting part 58 and the two side limiting parts 59, and the two pieces of food in the superposed state are automatically aligned, so that the two pieces of food are aligned; then the lifting cylinder 541, the two rotating shaft driving motors 56 and the two translation cylinders 5101 respectively drive the upper pressure plate 53, the front limiting part 57, the rear limiting part 58 and the two side limiting parts 59 to act and reset, the conveying belt 52 resumes running, the two pieces of sheet food which are aligned and calibrated are conveyed to the subsequent process, and the next set of two pieces of sheet food which are in a stacked state is prepared for alignment and calibration.
