The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. Instant coating laminating machine includes three parts: gluing, drying and hot pressing. It has a wide range of application and stable and reliable processing performance. It is currently widely used in China. Pre-coating laminating machine, no gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for laminating processing of large batches of printed products, but also suitable for laminating small batches and scattered printed products such as automated desktop office systems Processing is very promising.
        The pre-coating film machine part is as follows:
        1. Composite parts. The composite roller and calender roller group including the group. The compound roller is provided with a heating pressure roller and a silicone rubber composed of a pressure roller. The hot pressure roller is a hollow roller, equipped with a heating device inside, forging, polishing, fine grinding and processing of the hard chrome-plated surface; the hot pressure roller temperature sensor tracks the sampling and is corrected by the computer at any time; the composite material pressure adjustment eccentric cam mechanism Can be adjusted. The calender roll group is basically the same composite roll group, that is, the pressure roller composition is pressed with silicone gel from the pressure of the chromium roll, but there is no heating device.

        2. Computer control system. The computer control system uses a microprocessor, a main board configured with a laminator hardware, a numeric keypad, an optical isolator board, a power board, and a stepper motor power driver board. Print the input section. The automatic conveying mechanism can ensure that there is no overlapping and equidistant input of the composite part in the transmission. Generally, it is realized by accurate conveying and high-precision inflation or friction control. When the composite format is small font, it can also meet the above requirements of. Transmission system. The clutch high-power motor drive is controlled by a computer. After being decelerated by three chain-driven gears, the drive's paper feed mechanism and compound section and the calendering mechanism silicon pressure rollers rotate. Maintain proper working pressure, pressure roller group adjusts pressure steplessly.
