The automatic laminating machine is for laminating the surface of printed products, such as books, posters, color box packaging, handbags, etc. In response to the continuous improvement of global environmental awareness, oil-based lamination will be gradually replaced by water-based lamination. The new hot knife automatic laminating machine designed by our company is mainly for PET film. After laminating, not only can it directly enter the next process, but also the brightness and stiffness are relatively good. Exquisite packaging for cosmetics, cosmetics, high-end nutritional supplements and foods.
        The four most commonly used laminating processes in laminating machines in China today. Of course, among the laminating machines in China, the most common is water-based dry coating. Water-based dry-drying is to dry with coating glue and heat-recovering, and then slitting to paper collection. This laminating process should be the most versatile and popular laminating process in China; the second is the pre-coating film, which is a kind of glue itself already on the film, and then the paper comes in and heated with a roller, and then the film The glue above dissolves and sticks out. The third type is water-based wet-recovery. This process is a process in which the glue is not dried, but the paper is directly passed (only the pressure is not applied) and then rolled up. After it is naturally cured, the glue is absorbed by the paper and then pulled off. The fourth is the hot melt adhesive laminating process. All the previous three technologies have been covered by Tiancen and there are various models such as manual, semi-automatic and automatic. To put it simply, the core technology and competitiveness of Tiancen's automaton is to have hot knife cutting technology. At present, among all cutting, punching, flying knife, chain knife, hot knife and other technologies, hot knife is the most advanced technology in the world. The fastest speed and the most stable slitting. After slitting, the laminating product has no tail film and no film debris, which is the most ideal slitting method. Tian Cen uses this hot knife technology on water-based dry compound rubber, and uses hot knife slitting. The slitting needs to be very accurate, and the error of 1 or 2 mm cannot occur. Therefore, the precision of the machine manufacturing is very high. In the process of marketing and operation, customers are very interested in machines, especially high-end customers, because in the future the development trend of films, from the perspective of environmental protection and the quality of the film still need to use PET film. Nowadays, the majority of OPP films are on the market. OPP films can be cut off with a disc knife, and PET films are constantly pulled, and the entire film must be cut. Therefore, customers are very concerned about hot knife cutting technology.
        The head of the automatic laminating machine adopts the feeder head automatic paper feeding system, the pressing steel rod adopts the hot oil circulation heating system, the compound pressure adopts the pneumatic device, the electrical system adopts PLC programming control, and the cutting system is equipped with knife and rotation Flying knife slitting device, the back of the laminating machine is equipped with an automatic paper collection system, the whole machine occupies a small area, has a high degree of automation, simple operation and high stability.
        Pre-use inspection and analysis of automatic laminating machine:
        The automatic laminating machine is best to regularly check whether there is glue or grease on the rubber roller, and wipe the rubber traces and dust on the roller in time. Ensure that the appearance of the two rolls is washed black. The surface of each roller must be cleaned. Not only is it necessary to clean the machine immediately after using the machine each time. Wash with glue thinner and wipe the rollers with a soft towel. It is strictly forbidden to scrape the surface of the drum with a sharp tool. Every time the machine is turned on, the surface dust of each roller should be wiped off. Computer bronzing machine and check whether the appearance of each roller of the machine is black, when the machine shows defects or abnormal dynamics, it is necessary to analyze and find the reason and eradicate it in time, and wait until the machine is normal before allowing it to continue to operate.
        The blade line of the scraper blade of the automatic laminating machine should be flat and flexible. When the appearance of detours, teeth, curling, etc. should be trimmed and replaced in time, use 0.15 ~ 0.20 mm manganese steel skin or the blade of the offset press, press Exchange the original standard. Lubricant should be added to the transmission parts and sliding surfaces of the machine on time to ensure that the machine is in excellent lubrication conditions. Especially the large bearings of the pressure rollers are subject to high pressure and high temperature, and the lubricant is evaporated and thrown away at will. High temperature lubricating oil, so that it can operate normally under high temperature and high pressure. The floor formwork support of the automatic laminating machine uses the steel pipe bracket composed of the connection piece and the steel pipe, and gradually opens up perfectly as a fastener type steel pipe bracket.

       The precision of the automatic laminating machine is very high during the work process. Once a little spots, scratches, tortuous 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 flexible. When there are signs of detour, teeth, curling, etc., 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. Fully active laminating machine floor template support, using a steel pipe bracket composed of couplings and steel pipes, and gradually expanded into a fastener-type steel pipe bracket, because this bracket has simple processing, disassembly and assembly, flexible transfer, easy to use, and strong versatility. And other features, and soon spread to the whole country and the world.

        1. The glue part. The gluing part is equipped with an adjusting device to adjust the amount of gluing to meet the requirements of different printed parts. The gluing roller adopts rubber roller or steel roller.
        2. Drying part. The drying tunnel is generally 2 ~ 3m long. The drying tunnel entrance of the laminating machine is provided with an infrared lamp tube and an electric fan. The upper part of the drying tunnel of the automatic laminating machine also has a high-power electric heating tube and an exhaust fan, and the temperature can be adjusted to dry the adhesive and eliminate the exhaust gas.
        3. Hot pressing part. This part is the key to the fully automatic laminating machine, which is directly related to the adhesion fastness of the laminating products. The principle of hot pressing is that the adhesive can quickly infiltrate and penetrate into the surface layer of the printed matter in the molten state, so as to obtain a strong bonding interface layer. The hot pressing part is composed of a group of rollers. One of the hollow metal rollers is equipped with an electric heating tube, and the temperature can be controlled automatically. The pressure of this group of rollers can be adjusted.
        It is concluded that the laminating machine is 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.
        The main problems with the covers and sheets after being coated 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 is to punch a hole on the film after the film is coated and then break it. 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 scrap.

        What factors will affect the laminating of the pre-coating laminating machine? There are three main factors: temperature, pressure and speed. I will share with you in detail below.
        The first factor that should be paid attention to in the laminating of the pre-coating laminating machine: temperature
        Temperature is the first hub of laminating. The adhesive used for pre-coating is hot-melt adhesive. Temperature determines the melting state of hot-melt adhesive, determines the leveling function of hot-melt adhesive, and determines the direction of hot-melt adhesive molecules to BOPP. The diffusivity between three molecules of the film, printing ink layer, paper substrate and other substances also determines the crystallinity of the hot melt adhesive. Only by accurately controlling the temperature of the working area can the solid hot melt of the pre-coated film on the film be made The adhesive layer is completely melted into a viscous state, with suitable activity to achieve wetting and bonding to the surface of the printed matter, and at the same time to ensure immediate solidification after compounding, so that the laminated film product has a smooth appearance, bright enough, and the adhesive layer has a good degree of melting, no Crease. And can peel the ink.
        The temperature control of the laminating process also affects and determines the hot-melt adhesive used for laminating to solve the changes when heated, as well as the resistance to the new heat. Therefore, strict temperature control is the primary hub for precoating of precoating and precoating machines.
        The second major factor that should be paid attention to in the laminating of the pre-coating laminating machine: pressure
        While accurately controlling the laminating temperature, appropriate pressure should also be used. Because the surface of the paper itself is not very smooth, only under the pressure can the hot melt adhesive in the state of viscous flow be fully removed from the air on the surface of the printed matter. Wetting the surface of paper prints.
        Produce colloid molecules to the ink layer of paper printed matter, paper molecules diffusion, misalignment, achieve good adhesion, and form a complete coverage of the entire surface of the printed matter, so that the printed matter is bright, no fog, leveling of the glue layer, no folding Marks, good bonding effect, and without wrinkling, appropriate increase in pressure can make the thermoplastic curing performance of the hot melt adhesive fully manifest, to ensure that the laminating product is added to the process after compounding A variety of physical peeling, impact forces, etc. have a strong resistance to achieve the same speed of the internal structure and surface state of the composite printed matter.
        Paper lamination is a dynamic compound motion. The speed of the paper determines the time the paper-plastic composite stays on the thermocompression bonding interface, and also determines the input temperature, pressure, and temperature of the lamination machine. The actual action value of the paper-plastic composite during the actual production process.
        The third factor that should be paid attention to in the pre-coating laminating machine: speed
        When the two factors of lamination temperature and pressure are fixed, the change of speed will change the lamination effect, and because of the upper limit of temperature and the limitation of pressure supply, it will only change from the direction less than the set value, and will vary with the speed. Speeding up, the drop rate is significant, the heat and pressure force declines, and the composite effect deteriorates. The running speed is too fast, the bonding is not strong, there will be fog, and if it is too slow, it will be inefficient, and even bubbling. Therefore, the compound running speed determines the time for the pre-coated film and paper print to achieve bonding.
        The actual action value of the three factors of temperature, pressure and speed has a certain range. Because of the different equipment, we need to find the best effect value in practice to ensure the composite effect of the pre-coating film and create a favorable premise for the spine of the cover of the next step of the glue nail cover not to leave the shell and not foam.
