It will be appreciated that during actual drying, the air flow from the air knife 531 enters the circulation chamber through the ventilation holes and then returns to the fan 55 through the circulation connector 562. Since the airflow from the air knife 531 is heated by the heating assembly 54, the hot airflow can be continuously recycled during the drying process, so that the airflow can have a higher temperature after many cycles even if the power of the heated assembly is low. Therefore, on one hand, the air flow blown out by the air knife 531 can be ensured to have higher temperature, and the drying speed of the printed matter is ensured; on the other hand, the heating power of the heating assembly 54 can be controlled, thereby saving electric energy.
Furthermore, it will be appreciated that during the rotation of the fan 55, since the circulation chamber and the circulation joint 562 are equivalent to the fan 55 drawing air from the circulation chamber, a negative pressure is formed on the quick drying conveyor 514, so that the printed products are stably adsorbed on the quick drying conveyor 514, thereby ensuring the stable transportation of the printed products.

In addition, the waste pressing piece 2311 is slidably arranged on the waste pressing slide rail 2312, so that when the size of a to-be-printed product is changed, the waste pressing piece 2311 can be adjusted in a targeted mode, and the waste can be pressed down by the waste pressing piece 2311 to be separated from the film tearing rubber roller 211.
Of course, it should be noted that in other embodiments of the present invention, the waste material pressing member 2311 may be selected from other linear driving structures, and is not limited to the air cylinder or the electric push rod of the present embodiment.

If the pull gauge suction head 331 sucks the to-be-printed product while the rough positioning suction head 321 sucks the to-be-printed product, the to-be-printed product may be damaged. Therefore, in the present embodiment, the fine positioning mechanism 33 includes the first fine positioning driving element 333 and the second fine positioning driving element 335, so that in the actual positioning process, when the coarse positioning suction head 321 of the coarse positioning mechanism 32 sucks the to-be-printed product, the first fine positioning driving element 333 drives the pull gauge supporting plate 334 to ascend, so as to ensure that the pull gauge suction head 331 is separated from the to-be-printed product, thereby ensuring that the coarse positioning suction head 321 can stably suck the to-be-printed product and convey it above the printing platform 41.
