The working principle of the laminating machine is to first coat the adhesive on the plastic film through the roller coating device, heat it by the hot pressing roller to soften the film, and then press the printed matter coated with the primer and the film to form a paper Plastic laminated products. Working Principle of Existing Coating Laminating Machine Instant coating is a process in which the instant coating machine is used to paste the film immediately with the glue to carry out the paper-plastic composite process. It is mainly composed of a coating film processing plant or a processing workshop. According to the needs, the roll plastic film is coated with an adhesive, dried (lightly) compounded, and pressurized to adhere the paper film together to form a film-coated product. That is to say, the coating equipment has two kinds of automatic and semi-automatic, and the basic working principle is the same; the process flow mainly includes unwinding → sizing and coating → drying → compounding → slitting → finished product accumulation. The working principle of the pre-coated film laminating machine The pre-coating type laminating machine is a special equipment that combines printed matter with pre-coated plastic film. The main structure includes four major components: film unwinding, printed matter automatic input, hot-pressing compounding, and automatic winding. Compared with the instant coating laminating machine, it does not require adhesive coating and drying parts, so it is compact in structure, small in size, low in cost, easy to operate, ready to use, start-up, production flexibility, and high efficiency. The composite of the pre-coated film and the paper printed matter only needs to be hot pressed. It is suitable for all kinds of laminating machines, laminating machines and laminating machines with hot pressing function. That is, the bridge-type combined laminating machine of the glue-coating wet laminating process does not need to be modified, and it can be completely laminated with pre-coated film.
