Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive bonding technology, and in particular to an OPP film bonding auxiliary structure. Background Technology
[0002] OPP lamination is a process that coats the surface of printed materials, packaging materials, and other objects with a layer of biaxially oriented polypropylene (OPP) film. This process improves the physical and chemical properties of the coated object, while also providing protection and decoration. However, existing OPP lamination bonding structures cannot achieve precise alignment between the laminator and the material to be laminated, making it difficult to ensure complete overlap of patterns and text after lamination, leading to misalignment and lower lamination quality. Furthermore, the pressure applied to the material during lamination cannot be monitored in real time; excessive pressure can cause material deformation or film damage, while insufficient pressure can result in weak lamination, air bubbles, and other problems, reducing quality stability.

[0031] Working principle: The film and the material to be coated are placed on the processing table 1. The cylinder 4 is started, which pushes the drive plate 5.

The driven plate 8 drives the driven frame 9 to move. The driven frame 9 drives the connecting block 10 to slide inside the slide groove 11.

During the pressing process, pressure sensor 24 monitors the pressure applied by spacer 21 to the material in real time and converts the changes into electrical signals that are transmitted to controller 25. Controller 25 controls motor 15 to control the pressure of spacer 21, thereby improving quality stability.
