The automatic laminating machine is aimed at the surface lamination of printed products, such as books, posters, color box packaging, handbags, etc. In response to the continuous improvement of global environmental awareness, oily lamination will be gradually replaced by water-based lamination.
       (1) Hot pressing roller
        The hot pressing roller is a hollow roller with an electric heating device inside. The temperature of the roller is controlled by sensors and instruments on the console. The surface state and thermal power density of the hot pressing roller have a great influence on the quality of the coated product. The general lamination process requires a hot pressing temperature of 60-80°C and an area heat flow of 2.5-4.5W/cm2.
       (2) Rubber pressure roller
        Press the coated product against the heat press roller with a certain pressure to make it solidify and stick firmly. The contact pressure during compounding is closely related to the adhesive strength and appearance quality, and is generally 15.0 to 25.0 mPa. Rubber pressure rollers work under high temperature for a long time, but also to keep the roller surface smooth, smooth, small lateral deformation, good tear resistance and peelability, so silicone rubber with better tear resistance is mostly used.
       (3) Pressure adjustment mechanism

        It is used to adjust the pressure between the heat pressure roller and the rubber pressure roller. The pressure adjustment mechanism can use a simple eccentric mechanism, eccentric cam mechanism, screw rod, nut mechanism, etc. However, in order to simplify mechanical transmission parts and improve the accuracy of pressure control, most of them are currently Adopt liquid (gas) pressure type pressure adjustment mechanism.
