[0002] Printing machinery is a general term for mechanical equipment such as printing presses, binding machines, platemaking machines and other auxiliary mechanical equipment. These mechanical equipment have different performances and uses.

[0003] At present, when operators use printing equipment, they usually use related feeding equipment. However, since the sizes of printed materials are different, when the printed materials are of different sizes, the operator needs to replace the corresponding limit plate to perform the limiting operation, so as to limit the material to be printed to the middle of the feeding device to prevent deviation during printing. Although this replacement method can achieve an effective limiting effect, it is more troublesome for the operator to replace it, which wastes a lot of printing time, so it needs to be improved.
