Background The composition mechanism of the corrugated paper printing production linkage line generally comprises a paper feeding unit, a plurality of printing units, a slotting unit, a die cutting unit and the like, wherein the units work together in a unified and coordinated mode under the action of a power system and a transmission system, and a series of processing operations such as paper feeding, printing, slotting, die cutting and the like of corrugated paper boards are completed together. Meanwhile, after corrugated paper is cut into the required specification and size by a paper separator, counting and separating are carried out by a counting machine, the corrugated paper after being separated is bundled into a pile, and then the corrugated paper pile is conveyed to a stacker for stacking. The traditional counting machine adopts a mechanical contact type counting or photoelectric sensing counting mode, the mechanical contact type counting is easy to cause counting errors due to uneven surface of the paper board or fluctuation of conveying speed, and the photoelectric sensing counting is easy to be influenced by the color, reflectivity and dust environment of the paper board, so that misjudgment and missing counting phenomenon occurs. Meanwhile, the counted paperboards are required to be transported to a stacker through manual or independent conveying equipment, and the paperboards are prone to deviation and uneven in stacking in the process, so that the manual intervention cost is increased, and the overall production efficiency is reduced. In the prior art, the problem of poor speed matching exists at the paperboard conveying joint of the part integrated paper collecting counting equipment, when the paperboard enters the stacking mechanism from the counting mechanism, the paperboard is easy to collide and fold due to inconsistent front and rear conveying speeds, and especially, the paperboard with thinner thickness or printed patterns on the surface is extremely easy to cause product damage and influence the product quality. Moreover, the existing stacking mechanism generally relies on the self gravity of the paperboards to naturally fall and stack in the stacking process, so that accurate temporary storage and release control are difficult to realize for a preset number of paperboards, the side edges of the stacked paperboards are prone to uneven, an additional manual finishing process is needed, and the continuity of automatic production is further restricted.
