The pre-coated automatic laminating machine uses the pre-coated laminating process for lamination processing, without gluing and drying parts. The pre-coated automatic laminating machine consists of pre-coated plastic film unwinding, automatic printing input, hot pressing area It consists of four main parts: composite and automatic winding, as well as mechanical transmission, flattening of pre-coated plastic film, vertical and horizontal slitting, and computer control system auxiliary devices. The automatic conveying mechanism can ensure that the printed products do not overlap and enter the composite part at equal distances during the transmission. The automatic pre-coating film laminating machine is generally controlled by pneumatic or friction mode, and the conveying is accurate and the precision is high. In the case of printed products with small composite format, the above requirements can also be met.
        Pre-coating film coating technology refers to a professional manufacturer that pre-coats hot-melt adhesive on the BOPP in the molten state. After cooling and solidifying, it becomes a technology that can be firmly bonded by heating and pressing again. An emerging coating process. So what are the structural characteristics of the pre-coated film coating technology? The pre-coated film is composed of a substrate and an adhesive layer, and the substrate is usually PET and BOPP. There are two types of adhesive layer: molten type and solvent volatile type. According to the different processing technology and equipment conditions, different thickness of adhesive layer is selected. The thickness of the adhesive base layer is generally: 5-15um.

        The laminating machine refers to the transparent plastic film is applied to the surface of the printed product by hot pressing, forming a 10-20um film, which protects the printed product and increases the gloss of the printed product. The laminating process is widely used for surface binding and protection of book covers, picture albums, commemorative albums, postcards, product manuals, calendars and maps.
        The laminating process is mainly divided into semi-automatic laminating machine and fully automatic laminating machine. Although the specific operations of semi-automatic and full-automatic are somewhat different, the principle is the same: the adhesive is applied to the plastic film by a roller coating device, heated by a hot-pressing roller, the film is softened, and then the bottom is coated The printed material and the film are pressed together to form a paper-plastic integrated film product.
        According to the different raw materials and equipment used, the film coating process can be divided into coating film process and pre-coating film process. Instant coating refers to the process of using plastic film as the raw material during the laminating operation, firstly coating the adhesive on it, and after drying treatment, then hot-pressing the plastic film and the printed product. The pre-coating type refers to a process method in which a plastic film coated with an adhesive in advance and dried is used as a raw material, and is directly subjected to hot-press compounding with a printed product.

        The laminating of the automatic laminating machine is to coat the plastic film with the adhesive, and it is used with the printed matter using paper as the substrate, and the use of the rubber pre-coating laminating machine, the laminating is to coat the plastic film Agent, and it is combined with the printed matter using paper as the substrate after being pressed by the rubber cylinder and the heating cylinder to form a paper-plastic product. The printed product that has been coated with adhesive indentation machine has a thin and transparent plastic film on the surface, which makes the surface smoother and brighter, which not only improves the gloss and fastness of the printed product, but also extends the service life of the printed product. The film also plays a protective role such as waterproof, anti-fouling, abrasion resistance, folding resistance, and chemical resistance.
        If the transparent bright film coating is used, the printed graphics of the coated product will be more vivid and full of three-dimensional sense, which is especially suitable for the packaging of green food and other commodities, which can arouse people's appetite and consumption desire. If a matte thin film is used, the film product will bring a noble and elegant feeling to consumers.
        After the automatic laminating machine laminating the packaging and printing products, it can significantly improve the grade and added value of the commodity packaging.

        The precision of the automatic laminating machine is very high at work, especially the surface accuracy and shopping degree of each roller. Once the slightest streaks, cracks, scratches, obscuration, or a slight roundabout deformation. All will affect the processing quality of the product, even not working properly. Therefore, it is very important to protect the fully automatic laminating machine carefully and carefully.
        Daily maintenance method of automatic laminating machine:
        1. Always check the oil pipes, valves and cylinder plugs of the hydraulic system for oil leakage. When oil leakage is found, the sealing ring should be replaced in time, and the appropriate amount of hydraulic oil should be filled into the hydraulic cylinder in time;
        2. Always check whether the rubber roller is stuck with rubber skin or grease, and wipe the rubber traces and dust on the roller in time. Keep the two rolled surfaces clean and dark. The surface of each roller must be kept seriously clean. Always clean the machine immediately after applying the machine. Wash with glue thinner (alcohol or xylene) and wipe each roller with a soft towel. It is strictly forbidden to scrape the surface of the roller with a sharp tool. Every time the machine is turned on, the dust on the surface of each roller should be wiped off. And check whether the surface of each roller of the machine is dark, the machine is malfunctioning or abnormal sound, it should be analyzed in time to find the cause and clear it, and the machine can continue to be applied after everything is normal;
        3. The grounding of the machine and the insulation of electrical appliances should be ensured;
        4. The blade line of the scraping blade should be kept flat and flexible. When there are detours, teeth, curling, etc., it should be repaired and replaced in time. Use 0.15~0.20 mm of manganese steel skin or the blade of the offset press, according to the original specifications Change the size;
        5. Regularly add lubricating oil to the transmission parts and sliding surfaces of the machine to ensure that the machine is in a good lubrication state. Especially for the large bearings of the pressure roller due to the high pressure and high temperature encountered, the lubricating oil is volatilized and lost, and the dwarf high-temperature lubricating oil should be timely so that it can normally perform obligations under high temperature and high pressure;
        6. A comprehensive inspection of the machine should be carried out once a year to find the problem and solve it in time to avoid more serious damage to the machine.

        The laminating machine manufacturers adopt the advanced structure of automatic paper feeding and automatic paper cutting, which reduces the labor intensity of manual operation, improves the production efficiency, and guarantees the quality of the products. It is suitable for laminating all kinds of art prints. Laminating machine manufacturers will be widely used to process all kinds of book covers, pictures, packaging cartons, portable paper plastic bags, calendars, etc. It makes the color more vivid, clear lines, bright and beautiful, moisture-proof and stain-proof, and durable, it is the ideal equipment for the printing and packaging industry.
