Coating machine for PET (Polyethylene Terephthalate) film gluing

The utility model relates to the technical field of PET (Polyethylene Terephthalate) films, in particular to a coating machine for PET film gluing. The coating assembly comprises an assembly base, supporting supports, an upper top roller, a glue homogenizing cylinder, a glue inlet pipeline and a glue outlet, the supporting supports are symmetrically connected to the two sides of the upper end of the assembly base through screws, the upper top roller is located between the two supporting supports, the glue homogenizing cylinder is located above the assembly base, and the glue inlet pipeline is connected with the glue outlet. The glue inlet pipeline is evenly connected to the middle side of the upper end of the glue homogenizing cylinder through screws, and the glue outlet is formed in the middle side of the lower end of the glue homogenizing cylinder. Through the arrangement, under the mutual cooperation of the glue homogenizing cylinder and the glue coating roller, glue can uniformly flow out of the glue outl
