Novel heating and drying system for film printing

The utility model relates to a novel heating and drying system for film printing. The novel heating and drying system for film printing comprises a fan, wherein an air outlet and an air suction opening are formed in the fan; the technical key points include that the air outlet is communicated with a heating box; the air outlet end of the heating box is communicated with a drying box for the printing film to pass through; an exhaust port is arranged in the drying box; the exhaust port is communicated with a pressure reduction cavity; a waste gas exhaust port and a circulating airflow port are arranged in the pressure reduction cavity; the waste gas exhaust port is communicated with a main exhaust pipe; the circulating airflow port is communicated with the air suction opening. The novel heating and drying system for film printing has the advantages that the structure is simple, the drying airflow is stable, and the drying efficiency of the film printing is effectively improved.
