The state has issued a series of policies to rectify the heavily polluted printing industry, paper industry and other fields, causing many factories to close and close, resulting in increased costs, reduced competition pressure, and the application of negative pressure laminators has also begun to become widespread.
        What is a negative pressure laminator? It is to apply a plastic film with an adhesive, and then combine it with the printed matter using paper as a substrate, pressurized by a rubber roller and a heated roller, and form a paper-plastic integration product. The products made in this way not only improve the gloss and fastness of the printed matter, and prolong the service life of the printed matter, but at the same time, the plastic film also plays a protective role in waterproof, anti-fouling, abrasion resistance, and chemical resistance.
        What are its mechanical functions?
        1. Equipped with a non-stop paper feeding device to ensure continuous production;
        2. The use of large-diameter pressing rollers effectively improves the production speed and ensures that the composite products are flat and bright;
        3. A powder removal mechanism combining powder sweeping and powder pressing is adopted to ensure the powder removal effect;
        4. The advanced drying tunnel structure ensures that the glue on the film can be dried quickly;
        5. Adjustable speed disc-type rotary cutter to ensure the slitting of paper;
        6. The motor adopts frequency conversion control, safe and reliable.
        The above is my brief introduction to the mechanical function of the negative pressure laminator.
