Description

Technical Field

[0001] The utility model relates to the field of edge trimming devices, in particular to an edge trimming device for a protective film finished product roll. Background Art

[0002] The protective film finished roll trimming device is a device used to trim the edges of the protective film finished roll. Usually, a knife or cutting device is used to cut the edge of the finished roll to remove irregular edges and make it neat. This device can improve the appearance and quality of the product and ensure that the size of the finished roll meets the requirements.

[0003] When the existing trimming device is in use, since it uses a cutting disc or a cutting knife for trimming, long-term use can easily cause the temperature to increase. The temperature increase will cause the waste to adhere, reducing the cleanliness of subsequent trimming. Although some use liquid to rinse and cool the cut edges, the liquid will contaminate the cut surface.

[0004] In order to solve the above problems, the present application proposes a protective film finished product roll edge trimming device. Utility Model Content
