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.

        The pre-coated laminating machine combines it 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. Due to the thin and transparent plastic film on the surface of the printed product, the surface is 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. At the same time, the plastic film is waterproof and Protection against dirt, abrasion, folds, and chemical corrosion.
        In recent years, the coating is basically using a pre-coating film. Because it is not used for a long time and there are many problems. According to the process practice, the quality of the pre-coating film is mainly affected by temperature and pressure. The three factors of speed, so correctly handling the relationship between the three, is essential to ensure the quality of the pre-coating film and the impact on the production of the next process. Paper-plastic coating is the comprehensive result of the physical function of thermocompression bonding. Temperature, pressure, and speed are the three basic factors for achieving this physical comprehensive effect. Correctly handling the relationship between the three is the key to the process operation technology.
        Temperature: It is the first key to coating. The adhesive used for pre-coating is hot melt adhesive. The temperature determines the melting state of hot melt adhesive, the leveling performance of hot melt adhesive, and the molecular orientation of hot melt adhesive. The diffusion ability of three substances, such as BOPP film, printing ink layer, paper substrate, etc., also determines the crystallinity of the hot melt adhesive. Only by correctly controlling the temperature of the working area can the solid heat of the pre-coated film on the film be made The melted adhesive layer is completely melted into a viscous state, with suitable fluidity to achieve wetting and bonding to the surface of the printed matter, and at the same time to ensure immediate solidification after compounding. The laminated film product has a smooth appearance, bright enough, and the adhesive layer is well melted. No creases. And can peel the ink. The temperature control of the lamination process also affects and determines the hot-melt adhesive used in the lamination process to solve the changes when heated, and the resistance to the new heat. Therefore, strict temperature control is the primary key to pre-coating. According to our practice. Temperature control in the range of about 80 ~ 100C is more appropriate.

        The operation of the laminating machine and its safe operating procedures are very important to us, because it is related to the correct and safe operation of the machine and equipment, so it is necessary to carry out relevant understanding in order to do the homework in advance. To achieve the above purpose. So below, the editor will give a good introduction to this knowledge, so that everyone can understand and learn more clearly.
        1. Detection before startup
        (1) Whether the machine equipment is in a safe state, adjust the film transportation to make the film tension even.
        (2) Check the gap between the glue roller and the glue, and the temperature of the heating roller, whether it is normal, if any problems should be dealt with in time.
        (3) Check whether the pressure meets the specified requirements, clean the rubber roller, and remove debris.
        2. Processing at the end
        (1) After the work is completed, stop heating first, and wait until the temperature drops, then stop the motor and fan.
        (2) Clean the roller and rubber roller, add lubricating oil to lubricate the machine, and finally cut off the power of the machine.
        3. Safe operating procedures
        (1) There should be no flammable and explosive materials near the machine to avoid fire.
        (2) When the machine is running, the operator is strictly prohibited from making dangerous actions to avoid danger or accidents.
         (3) If the temperature of the roller is too high, do not touch it directly with your hands to avoid being burned.
         (4) The scrubbing of the machine should be carried out correctly, and it can only be turned on at a low speed.
         (5) When the machine is stopped, the hydraulic system should be unloaded, and the pressure roller and rubber roller should be separated.
        (6) The maintenance of the machine should be carried out in the state of power off.
        (7) Do not place any objects or even debris on the machine.
