The laminating machine can be divided into two types: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. The instant coating laminating machine consists of three parts: sizing, drying and hot pressing. It has wide application range and stable and reliable processing performance. It is a widely used laminating equipment in China. Pre-coated laminating machine, without glue and dry parts, small size, low cost, flexible operation, not only suitable for laminating processing of large-volume printed materials, but also suitable for coating of small batches and scattered printed materials such as automated desktop office systems. Processing is very promising.
            The vibration of the laminator mechanism is one of the important factors affecting the accuracy of the film. With the rapid development of the printing and packaging industry at home and abroad, all kinds of printing equipment and post-press processing equipment have developed by leaps and bounds. In the post-press processing, vegetable greenhouse filming technology has been widely used.

            In the existing laminating equipment in China, the difficulty is difficult to improve, which is the main reason that restricts its development. In the post-press processing, the laminating technology is widely used, and the high-speed, high-precision laminating machine is urgently needed in the market. Based on the analysis of the test technology principle, based on the Dongpu signal test and analysis system software, a relatively complete vibration test program of the laminator was selected, and the vibration test of the main components of the laminator was carried out. The results show that the vibration at the wallboard is the largest, followed by the front gauge shaft, and the movement of the side gauge shaft is relatively stable and the vibration is minimal.
