Specifically, the air suction assembly 9 is positioned in an air suction space formed by surrounding the belt 5, the driving shaft 3 and the first transmission shaft 4, so that the structure of the belt transmission mechanism 100 is compact, and the installation space is saved; because the area of the part of the belt 5 used for conveying the workpiece is larger, when one fan is adopted for adsorbing the workpiece, only the part of the belt 5 opposite to the air suction inlet of the fan has large suction force, and the part of the belt far away from the air suction inlet of the fan has small suction force, so that the smoothness of the workpiece on the whole conveying plane of the belt 5 cannot be ensured. In order to improve the adsorption capacity and the air suction uniformity of the air suction assembly 9, a plurality of air suction cavities are arranged in the air suction space, a fan is arranged in each air suction cavity, and the fan adsorbs a workpiece on the belt 5 through the belt through hole 51. The setting of a plurality of air suction chambers can make induced draft evenly, and every fan corresponds an area of belt 5, avoids belt 5 to keep away from the partial adsorption efficiency of fan poor, has increased the adsorption area of belt 5, can guarantee the planarization of work piece at the in-process of transmission, reduces the skew or the deformation of work piece in the transmission course, guarantees the transmission quality of work piece to improve this printed matter detection device's detection precision. In addition, the setting of a plurality of fans makes every fan only need very little power can guarantee adsorption quality, can the energy saving, and the power consumption is little, and every fan can be dismantled alone, can in time replace when one of them fan trouble, does not influence printed matter detection device's work, makes things convenient for printed matter detection device's maintenance simultaneously. For example, six fans are provided in the embodiment, and the total power of the six fans is 720W, so that the adsorption requirement of the workpiece can be met. Of course, the arrangement of the air suction assembly 9 is not limited to this, as long as the air suction assembly 9 can suck the workpiece onto the belt 5 through the belt through hole 51 on the belt 5.
