[0017] 1. Compared with the prior art, the folding machine for avoiding paper jams is provided with an installation box limit plate, a push-pull rod, a card block, a hinged seat, a lock frame, a first spring and a push rod. Before folding, the limit plate is adjusted according to the paper specifications, and the push-pull rod is pushed. The push-pull rod drives the card block and the limit plate, and the limit plate drives two sliders to move in the slide groove. The card block squeezes the lock frame, and the lock frame rotates and squeezes the first spring on one side. When the inclined surface on one side of the lock frame and the inclined surface on one side of the card block are out of contact, the first spring pushes the lock frame and makes it jammed on the card block. When the side where the two limit plates are close to each other fits the two sides of the paper, the push-pull rod is stopped, and the limit structure can limit the paper to prevent the paper from skewing when entering the folding box, which can effectively prevent the equipment from jamming due to the skewed displacement of the paper.

After the position of the limit plate is adjusted, the two threaded rods are rotated at the same time, and the two threaded rods drive the two mounting blocks, and the two mounting blocks drive the pressure roller to move downward. When the pressure roller moves to a position where it can fit with the top of the paper, the threaded rod is stopped from rotating, and the pressure roller can flatten the paper to prevent jamming caused by uneven paper and wrinkles.
