AI Technical Summary

Technical Problem

In existing technologies, the uneven surface of the sandpaper roll makes it easy for the packaging film to slip and loosen after being wrapped, and the labels are not firmly attached. It is suitable for temporary packaging occasions but lacks stability and reliability.

Method used

One end of the packaging film is aligned with the outer winding end of the abrasive cloth roll using a metal buckle, and then both are inserted into the metal buckle. The frictional resistance of the groove wall is used to clamp and fix the film, and a hot melt machine is used to fix it on the outermost layer to enhance the connection stability.

Benefits of technology

This improves the connection stability between the packaging film and the abrasive cloth roll, avoids the risk of slippage and loosening, and enhances the strength and reliability of the packaging.
