Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of PET film separation, and particularly relates to a holographic sublayer PET film stripping device and method for anti-fake identification. BACKGROUND

[0002] At present, the produced anti-fake identification is mainly digital query anti-fake identification. In this kind of anti-fake identification, it is divided into clear code anti-fake identification and hidden code anti-fake identification. The hidden code anti-fake identification is divided into scratch-off type anti-fake identification and uncovering type anti-fake identification. The uncovering type anti-fake identification is divided into paper uncovering type anti-fake identification and holographic uncovering type anti-fake identification. In the holographic uncovering type anti-fake identification, the PET film of the holographic sublayer cannot be recycled and utilized, which is mainly caused by the lack of the holographic sublayer PET film stripping device. Therefore, the holographic uncovering type anti-fake identification cannot be produced industrially. The waste rate caused by manual stripping of the PET film is high. The PET film stripped off is not completely stripped, and the holographic sublayer aluminum plating layer is attached to the PET film, so that the PET film cannot be recycled and almost all forms solid waste material, causing serious waste of the PET film.

[0003] Chinese patent CN203697653U discloses a PET transfer film stripping machine, which comprises a raw film cylinder, a stripping roller and a film winding cylinder. The raw film cylinder and the stripping roller are arranged on the same horizontal line, and the film winding cylinder and the stripping roller are arranged on the same vertical line. A hot air blowing system is arranged behind the stripping roller. The hot air blowing system comprises a hot air blowing nozzle, an air blowing valve and a gas conveying pipeline. The hot air blowing nozzle and the air blowing valve are connected through the gas conveying pipeline. A supporting rod is arranged directly below the hot air blowing nozzle, and the hot air blowing nozzle is opposite to the included angle between the two layers of films stripped off behind the stripping roller. The patent is mainly suitable for stripping operation of general PET transfer film, and is used for stripping of release film and raw film, and is difficult to meet the process requirements of stripping the PET film from the holographic sublayer of the anti-fake identification.
