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.
        The above is the overview of the laminating machine manufacturers. If you want to know more about the laminating machine, you can contact us, we will have someone to answer your questions.

        The effect of the laminating machine itself directly affects the quality of the printed matter and directly affects the interests of customers.
        The heating laminator melts the glue by heating, and then adheres the film to the printed matter by pressurization. The curling of the single-sided lamination has always been a headache. Especially for small lamination machines, then the heating lamination machine alone What causes curling of the facial mask?
        After many times using a small pre-coating hot laminating machine to test the printing of various materials, we found that the single-sided lamination curled, generally curled in the direction of the film, and could not be kept flat, wrinkled. If the mark is serious, it will automatically curl into a cylindrical shape, which will affect the effect of the subsequent process. The main reasons for single-sided film curling:
        1. The coated paper is too thin; although the current laminating machine is suitable for laminating paper prints of a variety of materials, the thinner the paper, the easier it is to deform and curl
        2. The paper has much water content and high humidity; the paper is loose and flat. Laminating machine should also pay attention to the direction of the paper strands, especially thick paper, to reduce the phenomenon of paper curling caused by rolling and stretching.
        3. When hot laminating, the pressure is too high, the temperature is too high, and the time is too long. The current working temperature and working speed of the heating laminating machine can be adjusted freely. When laminating various printed materials, it should be selected and set according to different materials. Temperature and speed.
        Product quality standard of hot laminating machine: the surface is clean, flat, no blur, good finish, no wrinkle, no foam, no paper-plastic separation, no powder foil marks. The degree of drying is appropriate, and there is no phenomenon of sticking the surface film or paper. Handle the relationship between paper, plastic film and the temperature, pressure and time when passing through the hot pressing mechanism during the laminating process. Pay attention to adjust the temperature, mechanical pressure and mechanical speed of the heat roller to avoid blistering and paper during laminating Problems such as poor plastic adhesion.

        The laminating process of laminating machine refers to the whole process of laminating pictures and photos, including film selection, film making, and cutting. Mainly used for post-production of advertising pictures and wedding photos. The pictures covered with film have high anti-corrosion, waterproof, dustproof, anti-wrinkle and anti-ultraviolet erosion performance, which can produce strong three-dimensional sense and artistic appeal. So what should we do before the lamination process?
        Inspection work before laminating machine:
        1. Detection before laminating machine ⑴ Confirm whether the machine is in a safe state.
        2. Film transport adjustment to make the film tension even to adapt to the film transport tension.
        3. Check whether the gap between the glue roller and the glue is parallel.
        4. Check the temperature of the heating roller to avoid inaccurate thermometer.
        5. The pressure that the pressure gauge must reach, otherwise the pressure will affect the product.
        6. Clean the sundries on the rubber roller, so as not to cause waste in the finished product.
        After completing the preparation work, close the main power switch, turn on the heating cylinder and the motor, then turn on the oil pump, adjust the flow rate of the laminating glue, and adjust the parallelism between the rollers. Adjust the measuring position of the paper on the feeding table, apply the film-coated glue, and turn on the drying tunnel for heating. After testing several sheets of film, adjust the heating temperature, pressure and air intake of the heating roller again until the effect is good, and then start normal work.
