The encoder and the control system are combined to control the pressing mechanism to stop after reaching the stroke position, so that the pressing mechanism automatically moves according to the type of cardboard, with a high degree of automation, and can improve the conveying stability of the paper pressing conveyor belt.

[0031] like Figure 1 As shown, the above-mentioned paper pressing conveying device of the printing linkage line also includes a translation mechanism 3 for driving the paper pressing conveying belt 1 to move forward and backward. The translation mechanism 3 includes a mounting beam 31 and a slide rail 32. The mounting beam 31 is provided with two and is arranged on both sides of the top plate 21. The slide rail 32 is arranged on the top of the mounting beam 31 and is arranged perpendicular to the paper pressing conveying direction. The top plate 21 is connected to a slider arranged on the slide rail 32. The top plate 21 is also provided with a limit bolt for limiting the movement of the slider. The entire device is fixed by the mounting beam 31. By loosening the limit bolt, the position of the top plate 21 (i.e., the paper pressing conveying belt) on the slide rail 32 can be adjusted so that the paper pressing conveying belt 1 is aligned with the carton. After adjustment, the limit bolt is tightened and the top plate 21 cannot move anymore. In this embodiment, since the adjustment of the pressing conveying belt 1 in the front and rear directions is less, manual translation is adopted to save costs, but it can also be modified to an electric screw translation structure as needed.
