[0063] By turning the hand wheel 101, the hand wheel 101 can synchronously drive the positive and negative screws 102 and the positive and negative screws 2 107 to rotate, thereby adjusting the spacing between the two triangular plate bins 2 and the width of the square plate bin 8.

[0064] In this embodiment, the automatic feeding mechanism for the folding box sheet material is additionally provided with a width adjustment function, so that it can adapt to square sheets of different widths and has good versatility.

[0065] The working principle of the automatic feeding mechanism for folding box plates in this embodiment is as follows:

[0066] First, the operator can place the triangle plate on the two triangle plate bins 2 and the square plate on the square plate bin 8 respectively, start the machine, and the two triangle plate suction devices 5 can respectively suck up the triangle plates on the two triangle plate bins 2, and place the triangle plates on the two triangle plate positioning devices for position correction and positioning under the drive of the primary translation drive device 4. After that, the primary translation drive device 4 drives the triangle plate suction device 5 to return to its original position, and the secondary translation drive device 7 drives the triangle plate positioning device 6 and the triangle plate to move horizontally to the rear end, and synchronously drives the square plate translation push device 9 to push the square plate in the square plate bin 8 horizontally to the rear end, until the triangle plate and the square plate are synchronously aligned and moved to the specified position, at which time the triangle plate is located on the left and right sides of the square plate. Subsequently, the secondary translation drive device 7 drives the triangle plate positioning device 6 and the square plate translation push device 9 to return to their original position, and this cycle is repeated.
