Description

Laminated glass trimming device Technical Field The utility model relates to the technical field of glass cutting tools, in particular to a laminated glass trimming device. Background The laminated glass is a composite glass formed by permanently bonding two or more layers of glass with one or more layers of organic polymer intermediate films sandwiched therebetween. It has the characteristics of safety, sound insulation, ultraviolet resistance and the like. However, because the intermediate film (such as PVB, EVA and the like) has toughness, the conventional glass knife cannot be cut regularly at one time, so that the laminated glass is more complicated than the common glass in trimming, the glued laminated glass is trimmed, the glass cutter is required to scratch the surface glass layer to form scratches, then the glass cutter is used for cutting along the scratches, the intermediate film is softened by using a hot air gun, and finally the intermediate film is trimmed by using an art designer knife, so that the whole process is extremely complicated.
