(1) Using instant film as the cover can protect the paper. After laminating, the service life of the cover (or the surface of the printed product) can be extended, especially for students' textbooks, so the amount of use is increasing.
        (2) Imprints are not easily destroyed. After being coated with a ready-to-use film, it can increase the color effect and protect the color printed graphics without being worn. This is conducive to the publishing house editors to make various art designs on the cover or printed surface according to their needs, so it also promotes the increase in usage.
        (3) The production of coating film is beneficial. The cost of making ready-to-coated film in lamination is low, easy to get started, and profitable, and enterprises can benefit.
        The above three points make the instant coating film "hot", but the quality problems of the instant coating film and the impact on the binding quality, but few people pay attention to it, the following will further analyze this.
        The main problems with the covers and sheets after laminating with instant coating are:
        The surface blisters, wrinkles, uneven bending, separation and separation, and not easy to store, etc. These quality problems have not been solved for many years, the reasons are also many, such as:
        1. The effect of different paper types. 2. The influence of different ink colors. 3. Different climate effects. 4. Influence of environment and conditions. 5. Enterprises lack the influence of scientific management. 6. The impact of personnel quality.

        The first slitting method on the laminating machine is to punch a hole on the film after lamination and pull it off. This method is suitable for manual machinery.
        The second is the hot knife slitting we want to introduce:
        1. Hot knife slitting technology is suitable for all films, especially PET film, aluminized film, etc. It is characterized by high slitting speed, precise slitting, no tail film, and can smoothly enter the next process without adding labor.
        The film laminating machine of this slitting method is suitable for the packaging of high-grade carton, such as the exquisite packaging of high-grade alcohol, cosmetics, high-level nutrient supplements and food.
        2. The hot knife active laminating machine can directly make gold and silver cardboard. Gold and silver cardboard of various colors are widely used on the delicate packaging of many alcoholic and cosmetic products. The cost of these gold and silver cardboard is relatively high. Aluminium-coated film can be directly laminated to various types of gold and silver cardboard in the hot knife laminating machine. A sum of money.
        3. The hot knife active vertical laminating machine can also make colorful glue directly. At present, a new bright spot has emerged in the field of laminating ---- colorful laminating adhesive, its birth adds a bright color to the laminating technology.
        The third cutting method is to use a "chain knife", but there are tail film, broken film, especially thick paper, the tail film is more significant, which has an impact on the next process.
        The fourth slitting method is to use a fast-rotating flying knife to cut a gap in the coated product, and then pull it off, but the laminated product is not accurate, and it simply presents waste products.

        The application skills of laminating machine during cold lamination, the laminating machine manufacturer tells you the steps of laminating machine during cold lamination:
        1. Be sure to wait for the blot to dry before laminating, otherwise it will cause blistering or hair pulling.
        2. The temperature is generally controlled at 40～60℃. Too high a temperature will deform the paper and film, causing the product to curl, but not too low, otherwise it will cause insufficient viscosity. The temperature of coated paper should be slightly lower than that of offset paper.
        3. The product to be constructed must be straight. Handle uneven paper with "ruffled edge" and "tight edge" phenomena. Paper with "lotus edge" can be baked, and paper with "tight edge" can be hung to dry.
        4. Pay attention to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching.
        5. Spray as little powder as possible during printing, otherwise it will cause emptying and bubbling at the pile of powder. Before spraying the film, the powder should be disposed of. If the number of prints is large, the powder can be hung to remove the powder. If the number of prints is small, the powder can be wiped manually.

        The precision of the automatic laminating machine is very high during the work process. Once a little spots, scratches, roundabout deformations or fine cracks will affect the processing quality of the product, even the automatic laminating machine will not work properly. jobs. So it is very important to maintain the machine carefully.
        Maintenance starts with basic little things. The automatic laminating machine should always check whether there is rubber or grease on the rubber roller, and wipe off the rubber marks and dust in time to ensure that the surfaces of the two rollers are clean and dark. It is necessary to keep the surface of each roller clean every day. After using the machine each time, it is necessary to clean the machine immediately, rinse with glue thinner and wipe the rollers 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. Computer bronzing machine and check whether the surface of each roller of the machine is dark. If the machine has shortcomings or abnormal movements, it should be analyzed in time to find the reason and be eradicated. After the standby device is normal, the machine can be used continuously.
        The blade line of the scraper blade of the automatic laminating machine should be flat and elastic. When there are appearances such as detours, teeth, and curling, it should be trimmed and replaced in time, and replaced according to the original standard scale. It is necessary to add lubricating oil to each transmission part and sliding surface of the machine regularly to ensure that the machine is in a smooth state, especially the large bearing of the pressing roller is suffering from high pressure and high temperature, and the smooth oil is randomly evaporated and lost. , So that it can be normally responsible under high temperature and high pressure.
        Full-automatic laminating machine floor formwork support, using a steel pipe bracket composed of couplings and steel pipes, and gradually expanded to a fastener-type steel pipe bracket, because this bracket has simple processing, disassembly and assembly, flexible transfer, easy transfer, and strong versatility. And other features, and soon spread to the whole country and the world.

        The laminating of the automatic laminating machine is a process in the later stage of printing. The first thing is to cover the surface of the printed product with a layer of plastic film to achieve the effect of the printed product becoming smoother and brighter. The automatic laminating machine is divided into several categories according to the temperature and use of the original data used by the various materials and equipment. The laminating skills completed by the equipment are analyzed in the following categories.
        1. Cold mounting: The method of mounting the protective film on the surface of the image by cold pressing at normal temperature is called cold mounting, and there are single-sided mounting and double-sided mounting in between. There are also manual peeling and self-releasing films in the operating method Framed. 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.
        2. Hot laminating of laminating machine: The method of laminating 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. Because of its good light permeability and water resistance, and strong hardness, it is suitable for the 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. The automatic laminating machine vacuum laminating is to use a special vacuum laminating machine to evacuate the film and the painting and set it at a certain temperature to complete the laminating. Its operation method is messy, the cost is large and the picture scale is subject to certain. Limited, but the mounting quality is very high, the picture texture is strong, suitable for photos.
