[0033] Working principle of the embodiment:

[0034] When the cloth stacking machine stacks the cloth, the rotating assembly 33 drives the rotating shafts 32 on the two support seats 31 to rotate synchronously, and then the cranks 34 connected to the rotating shafts 32 rotate around the rotating shafts 32. Since the crank 34, the connecting rod 36, the movable plate 21 and the cloth stacking workbench 1 are combined to form a four-link mechanism of the crank 34 rocker, the movable plate 21 swings up and down around the hinged shaft 212 under the rotation of the crank 34. Since the cloth is conveyed through the conveying rollers 4, the lower guide rollers 9, the conveying belt 7 and the upper guide rollers 8 between the two movable plates 21, the conveying belt 7 and the rollers will collectively raise or lower the cloth under the swinging of the movable plate 21. When the cloth tension increases, the cloth is lowered to slow the sharp increase of the cloth tension. When the cloth tension decreases, the cloth is raised to slow the sharp decrease of the cloth tension, thereby simply reducing the cloth tension change range and avoiding the cloth being pulled off.

[0035] When the cloth slightly deviates from the folding position, the servo motor 64 drives the rotating shaft 62 to rotate, and then the rotating shaft 62 drives the two bevel gears 63 to mesh and drive the two bevel gears 61. Since the two bevel gears 63 are located on the side of the two bevel gears 61 close to the servo motor 64, the two bevel gears 61 will rotate in the same direction, drive the two belt rollers 5 to rotate, and finally the conveying belt 7 will move under the rotation of the two belt rollers 5, and at the same time, the two ends of the cloth connecting plate 22 are pulled to translate by friction, so as to adjust the cloth to return to the original folding position by this way, so as to ensure the cloth stacking quality of the cloth stacking machine.
