TECHNICAL FIELD
[0001] The utility model relates to the technical field of film material processing auxiliary device, and specifically relates to a film material tension adjusting device. BACKGROUND
[0002] The tension adjustment of film material is an important link to ensure the optimal performance of film material in the production and application process.
