Description

A kind of BOPP film is rolled into the tension detecting apparatus of product

Technical field

Film roll tension force detection technique field is the utility model is related to, more particularly to a kind of BOPP film is rolled into the tension force detection of product Device.

Background technology

Biaxially oriented polypropylene cigarette packing film abbreviation BOPP cigarette packaging films.BOPP cigarette packaging films cutting be into During product film roll, for the regularity of film roll end face, the tension force of film roll generally all controls bigger, this makes film roll all relatively tighter. Usually from production to tobacco factory using this period of time, since film roll is in the state of internal stress all the time, the performance of film roll also occurs Some changes, or hardened phenomenon occurs, cause cigarette film on smoke machine using not smooth.If tension force loosens, film roll can go out again Existing end face is uneven, and string side phenomenon, the serious refill that there is also comes off, and influences product appearance.So cigarette packing film makes Detected with the preceding tension force that must carry out finished film；Now on the market also without the equipment occurred for detecting film roll tension force.
