Problems and solutions in the laminating process of the laminating machine.
        One: crumpled paper
        1. The film pulling force produces vertical folds of folded folds. Adjust the film tightness;
        2. The film itself is loose and uneven. Adjust the film transmission stick;
        3. The pressure is too high, the temperature is too high, horizontal wrinkle, adjust the pressure, and temperature;
        4. The rubber pressure stick is deformed, disassemble the pressure stick, and regrind;
        5. The paper is damp, keep the working environment and paper products dry or use drying in laminating;
        Two: wrinkled film
        1. If the temperature is too high, reduce the temperature appropriately and reduce the pressure to adjust the temperature required for various membranes;
        2. Adjust the imbalance of the film feeding stick, adjust the balance of the film feeding stick;
        3. The film stacking time is too long, replace the film;
        4. The film tension is too large or too small, adjust the film tightness;
        Three: There are snowflakes on the product
        1. Too much powder sprayed on the printed matter, sweep away the powder sprayed on the printed matter before laminating;
        2. The pressure of the pressure roller is inappropriate, the solution is to adjust the pressure of the pressure roller correctly;
        3. If the temperature is too low, adjust to an appropriate temperature;
        Four: bubbles appear

        The pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-press area compounding, and automatic rewinding, as well as mechanical transmission, pre-coating plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices. The automatic conveying mechanism can ensure that the printed products do not overlap and enter the composite part at an equal distance during transmission. Generally, pneumatic or friction methods are used to achieve control. The conveying is accurate and high precision. The same requirements can also be met when printed products with small composite width.
