[0006] Furthermore, a winding roller is axially connected to the inner side of the pharmaceutical composite film conveying frame; and a packaging film is rolled up on the surface of the winding roller, and a material guide roller is axially connected to the inner side of the coating composite mechanism.

[0007] Furthermore, a coating cylinder is installed at the right end of the guide roller, a glue delivery cavity is opened inside the coating cylinder, and the coating cylinder is connected to the glue delivery pipe through the glue delivery cavity.

[0008] Furthermore, a composite pair of rollers is axially connected to the right side of the coating cylinder; and the composite pair of rollers is located at the feed slot on the left side of the curing box.

[0011] Furthermore, the cooling fan, the air supply cavity plate, the air supply pipe, the flow-blocking baffle and the cooling air cavity constitute a temperature regulating structure of the curing box.

[0012] The beneficial effect of the utility model lies in that the pharmaceutical packaging composite film preparation equipment of the utility model utilizes multiple groups of horizontally arranged five-blade fans in the curing box and is distributed on the upper and lower film surfaces of the pharmaceutical packaging composite film.
