The invention discloses polylactic acid film manufacturing equipment. Its winding device includes a winding frame, a winding mandrel, friction rollers mounted at the lower part of the winding frame, lifting slings arranged on the top, shaft releasing mechanisms installed on frame wall plates on both sides, sliding shaft mechanisms arranged outside two ends of the friction rollers, and a pulling mechanism in front of the friction rollers. The friction roller is a rubber roller with continuous rhombic groove patterns on the surface and a diameter of 380–400 mm, and a film pressing roller is arranged behind the friction roller. The equipment facilitates the placement of the winding mandrel in contact with the friction roller and easy unloading of heavy finished film rolls. It overcomes the difficulty in flattening polylactic acid films to ensure finished product quality. Meanwhile, the water removal device is optimized to thoroughly eliminate surface moisture before corona treatment.
