[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the protection scope of the utility model.

[0014] like Figure 1-Figure 2As shown, an alignment device for cardboard printing includes a roller conveyor 2 and two slides 3. The roller conveyor 2 is installed on the outside of the feed port of the printing machine 1. The two slides 3 are movably installed in the feed port of the printing machine 1 along the transverse direction. A driving mechanism for driving the two slides 3 to move synchronously is installed at the feed port of the printing machine 1. The opposite ends of the two slides 3 are fixedly connected to fixed push plates 4. The fixed push plates 4 are longitudinally arranged and extend into the roller conveyor 2. The opposite sides of the two fixed push plates 4 are fixedly connected to two slide rods 41. The two slide rods 41 located on the same fixed push plate 4 are movably sleeved with sliders 5. The slider 5 is a longitudinally arranged strip structure, and a movable push plate 6 is fixedly connected to the upper part of the slider 5. The movable push plate 6 is arranged above the fixed push plate 4 and is parallel to the fixed push plate 4. When the slider 5 abuts against the fixed push plate 4, the inner side surface of the fixed push plate 4 is flush with the inner side surface of the movable push plate 6. A lifting longitudinal rod 7 is installed on the slide seat 3 for longitudinal sliding. A connecting rod 8 is hinged between the lifting longitudinal rod 7 and the adjacent movable push plate 6. A lifting cross bar 9 is commonly penetrated by the top ends of the two lifting longitudinal rods 7 along the transverse movement. A lifting mechanism is provided on the upper part of the printing machine 1, and the lifting mechanism is used to drive the lifting cross bar 9 to move up and down.

[0015] In actual use, cardboards can be continuously stacked on the roller conveyor table 2, and the driving mechanism can be used to drive the two slides 3 to move, so that the two fixed push plates 4 can directly align the cardboards under the cardboard pile, and the lifting mechanism can be used to drive the two movable push plates 6 to reciprocate to align the cardboards just placed on the cardboard pile with the cardboards below. It has the function of a traditional alignment device, but the two movable push plates 6 are driven by only one lifting mechanism and do not need to be driven by the cylinders 160 respectively, which saves energy and reduces the difficulty of debugging.

[0016] In this embodiment, the driving mechanism includes a motor 10, a bidirectional screw 110 and a first guide rod 120. The bidirectional screw 110 and the first guide rod 120 are both installed horizontally in the feed port of the printing machine 1. The slide 3 is slidably installed on the first guide rod 120. The two slides 3 are respectively threadedly connected to the threads of the bidirectional screw 110 with opposite rotation directions.
