Description

Technical Field

[0001] The utility model relates to the field of composite film production and manufacturing equipment, in particular to a high-pressure air knife puncturing bubble mechanism. Background Art

[0002] At present, the exhaust method used in the existing solvent-free film composite exhaust machine equipment usually uses a blade to make a longitudinal cut on the film at a certain width dimension to make a surface cut on the material position where bubbles may be generated.
