        According to the function of the laminating equipment and the characteristics of the composite film, it is divided into two forms.
        1. Dry compounding. Finished on the laminating machine. The compounding process is: first of all, how many laminating methods are available for the thin sticker on the roll?
        The coating of the sticker label laminating machine material is basically a transparent BOPP film compounded on the paper material to achieve the purpose of protecting graphics, waterproofing, anti-corrosion, and increasing the three-dimensional feeling of the label. Other types of films, such as in lamination, are not commonly used. Due to the high cost, the coating of paper web materials has been gradually replaced by a glazing process.

        The vibration of the laminator mechanism is one of the important factors that affect the accuracy of the laminating machine. 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 technology, the laminating technology is widely used. With the continuous improvement of customers' requirements for laminating technology, a high-precision laminating machine is urgently needed.
        In the existing domestic laminating equipment, it is difficult to improve the accuracy as the main reason restricting its development. In the post-press processing process, the laminating technology is widely used, and the market urgently needs high-speed, high-precision laminating machines. Based on the analysis and testing technology principles, based on the Donghao signal test and analysis system software, a more complete laminator vibration test program was selected, and the main mechanism components of the laminator were subjected to vibration tests. The results show that the vibration at the wallboard is the largest, followed by the front gauge shaft, the side gauge shaft moves more smoothly, and the vibration is the smallest.

        The function of the fully automatic laminating machine is that the laminating is a main process in the later stage of printing. The main reason for the automatic laminating machine is to make the printed products have a smoother and brighter effect. The method is to cover the surface of the printed products with a layer of plastic film. Automatic laminating machine is mainly divided into cold laminating laminating machine and hot laminating laminating machine according to its use principle and technology.

Automatic laminating machine is mainly divided into cold laminating laminating machine and hot laminating laminating machine according to its use principle and technology.
        Cold laminating machine: cold pressing method is used to mount the protective film on the surface of the image at normal temperature. It is called cold laminating, and there are single-sided lamination and double-sided lamination during the operation. Film mounting. The cold mounting technique has the characteristics of simple operation, good effect and low cost. It is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.
        Hot laminating film machine: The method of mounting the dedicated hot film on the equipment heated to a certain temperature (about 100-180 ° C) is called hot laminating, which can be divided into single-sided hot lamination and double-sided hot lamination Good light permeability and water resistance, strong hardness, suitable for post-production of advertising images in other occasions. However, hot laminating equipment and consumables are more expensive, with messy operations, high energy consumption, and high costs. Laminating machine vacuum laminating is to use a special self-adhesive indentation machine to evacuate the film and the painting at a certain temperature to complete the lamination. Limited, but the mounting quality is very high, the picture texture is strong, suitable for photos.

        In the printing industry, automatic laminating machine is indispensable, and its working efficiency has been widely recognized, so what are the characteristics of automatic laminating machine? The following editor will take you to know together!
        Automatic laminating machine is a kind of printed material that is made of plastic film through machine processing and printing on paper. This is widely used in people's daily lives. It is mainly used in magazines, book covers, packaging boxes, calendars, paper bags, etc. It can be said to be everywhere. In the past, traditional laminating machines had low working efficiency and high labor costs. Nowadays, people have invented automatic laminating machines, which use modern advanced laminating technology to automate paper feeding and cutting, which greatly improves production. Efficiency, reducing the cost of manual input. Not only that, the color of the product after the automatic laminating machine is more beautiful and beautiful, and it is moisture-proof, easy to clean, and durable. Automatic laminating machine is generally composed of three parts: gluing, drying tunnel and hot pressing. For gluing, it mainly uses an adjustment device to adjust the amount of gluing to meet different needs. The drying tunnel mainly uses electric heating tubes and fans to complete the drying of the adhesive on the drying tunnel of 2 to 3 meters. Hot pressing is mainly to obtain a firm interface layer and achieve the purpose of being durable.
        What are the coating forms of the automatic laminating machine? The main ones are roller reversal type, concave type, direct glue without scraper, and direct glue with scraper.
        1. Concave glue application. It consists of a metal glue roller with a textured surface and a group of film partition rollers. The glue roller is directly immersed in the glue solution, and the glue solution is taken out from the glue storage tank with the rotation of the roller. The excess surface is scraped off by the scraper Glue. Under the action of the film pressing roller, the glue in the groove of the roller is driven by the film to be coated which is directionally moved and is evenly spread on the film surface. The amount of glue can be controlled by adjusting the grid pattern on the surface of the coating roller shaft, the characteristic value of the adhesive, and the pressure value of the laminating roller. The advantage of concave coating is that the amount of coating can be controlled more accurately and the coating is uniform; however, the anilox roller is difficult to process and easily damaged, and needs to be cleaned frequently. In addition, the coating requires higher adhesives.
        2. Roller reversal glue application. It is an indirect glue coating, which is the most widely used by various models. . The glue supply roller brings out glue from the glue storage tank, and the glue scraping roller and the glue plate can scrape the excess glue back to the glue storage tank. The film counter-pressure roller of the laminator presses the film to be coated against the surface of the glue roller after the glue is homogenized, and maintains a certain contact area, and the glue solution is continuously coated on the film surface under the action of pressure and adhesion. The amount of glue can be changed by adjusting the distance between the rubber roller and the rubber roller, and the rubber roller and the rubber sheet.
        3. No-squeegee roller squeeze coating. The glue roller is directly immersed in the glue liquid. During the coating, the glue roller brings out the glue liquid and passes through the glue roller.

        Heating laminating machine can be divided into two major categories of instant coating laminating machine and pre-coating laminating machine. The instant coating laminating machine includes three parts: gluing, drying and hot pressing. It has a wide application range and stable and reliable processing performance. It is a pre-coating laminating machine widely used in China at present. There is no gluing and drying part, and the volume is small. The low cost and flexible and convenient operation are not only suitable for the laminating processing of large quantities of printed products, but also suitable for the laminating processing of small batches and scattered printed products such as automated desktop office systems, and have great development prospects.
        The laminating process is a surface processing process after printing, which is also known as post-press lamination, post-press laminating or post-press laminating. It refers to using a heated laminating machine to cover a layer of 0.012 ～ 0.020 on the surface of the printed product. mm thick transparent plastic film to form a paper-plastic integration product processing technology. The laminating machine is the equipment used to complete the laminating process. Generally speaking, it can be divided into two types: instant coating film and pre-coating film according to the process used, and it is divided into two kinds of bright film and matte film according to the different film materials. Can be divided according to other standards, not elaborated here.
        This type of heating laminating machine is widely used in photo agencies, printing plants, advertising, design and stickers. It has less investment and obvious effects. The consumables used are non-polluting. They are green and environmentally friendly products and have great market potential. More important labor is also less. Today, with high labor costs, less labor and more machinery are definitely the dream pursuit of many manufacturers. Moreover, another advantage of using this type of automation equipment is that the quality of the products produced and processed is balanced and the quality is not low. Avoid the poor quality caused by labor.
