AI Technical Summary
Technical Problem
In existing technologies, friction is easily generated at the opening of the packaging bag during the straightening process, which can lead to wrinkles, detachment, or deformation, affecting the folding effect.
Method used
An air-floating bag opening straightening device is adopted. Through the air blowing component and drive component installed on the packaging bag folding machine, the airflow is used to straighten the packaging bag opening, ensuring that the friction is matched with the conveying speed of the packaging bag.
Benefits of technology
This ensures the packaging bag opening maintains its shape stability before folding, improves the folding effect, and avoids wrinkles and deformation caused by friction.

Abstract
This invention provides an air-floating bag opening straightening device, which solves the problems in existing technologies where friction occurs between the bag opening and the protective plate during bag opening straightening, or where the bag conveying speed is difficult to match with the belt speed of the bag folding machine, easily leading to wrinkles, detachment, or deformation of the bag opening, resulting in poor folding effect. The device is installed on the upper side of the bag folding machine and includes a fixed base, two rotating shafts, two swing frames, a drive assembly, and two air blowing assemblies. The two rotating shafts are rotatably connected to the fixed base; the two swing frames are fixedly connected to the two rotating shafts respectively; the drive assembly is disposed on the two rotating shafts; the two air blowing assemblies are respectively located below the two swing frames and fixedly connected to the swing frames; a second gap is provided between the two air blowing assemblies for the bag to pass through, and a first gap is provided between the two swing frames, the first gap being larger than the second gap; the two air blowing assemblies blow air into the second gap respectively.
