The hot laminating machine instant coating laminating machine includes three parts: gluing, drying and hot pressing. It is a pre-coating laminating machine widely used in China at present. There is no gluing and drying parts. It has small size, low cost and flexible operation. Convenient, not only suitable for laminating processing of large quantities of printed products, but also suitable for laminating processing of small batches and scattered printed products such as automated desktop office systems, which has a promising future.
        The laminating process is a surface processing process after printing. It is also known as post-press lamination, post-press laminating or post-press laminating. It refers to the use of a laminating machine to cover a layer of 0.012 ～ 0.020mm on the surface of the printed product. The thick transparent plastic film forms 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 two kinds of bright film and matte film according to the different film materials.
        This type of thermal laminating machine is widely used in photo agencies, printing plants, advertising, design and adhesives. 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.
        Operation process steps of hot laminating machine:
        The first step is to use a bracket to stabilize the thermal laminator and fix it firmly on the workbench. To make a special platform for laminating, this step is actually to fix the machine and arrange the platform for laminating. This is the beginning and the key step. Whether the product has a good laminating effect is the key.
        The second step is to fix the material needed for the film on the iron roller, and the film coating is facing upward, adjust the pressure of the rubber roller, slowly adjust it, and remove the material that needs to be coated from the middle of the rubber roller and the machine. Just wear out more than 10 centimeters.
        The third step is to tighten the product and adjust the position, which is a good display of the effect of the film when the product is used, and has become a key point of elaborate production. In addition, in the early operation, we must pay attention to the effect of fixing the product to avoid skew.
        The fourth step, if you need to mount the film, you need to pass the cold laminating film out of the two rubber rollers of the laminating machine, 10 cm, and place it on top of the consumables. position. The pressure on both ends must be the same.
        The fifth step, when there is a slanting phenomenon in the process of use, it means that you have not placed it properly, and it should be carried out after being placed. You can go for a short time, cut it off slowly, re-center it, and start the machine to work. (Remind everyone, you must be even and stable when you are correcting, take your time)
        The sixth step, if there are wrinkles, don't stop the machine immediately, let him continue to run for a while, then stop the machine, and slowly take out or cut the film, if you are using a cold laminator, it may be There will be excessive pressure, because the machine itself has not completely stopped, and the problem can be solved after the machine stops.
       The above is a detailed explanation of the steps of the operation process of the hot laminating machine. If you have any questions, please call our factory for consultation. There will be professional technical staff to teach you how to do it.

        Quality standard after laminating machine printing:
        1. The color of the printed pattern remains unchanged, and it will not change color under the sun, baking and ultraviolet radiation.
        2. The film is firmly bonded, the film layer cannot be easily separated, the surface is clean and smooth, not blurry, good finish, no wrinkles and powder foil marks. Any wrinkles and creases are considered unqualified products.
        3. The film-covered product must not be curled, the size after division is accurate, the edges are flat and smooth, and no film or film loss can occur. The break is no more than 4㎜.
        4. The degree of drying after coating is appropriate without sticking to the surface. On thick solid and dark areas of the ink, there should be no sand bumps, stripes, or worm-like film bumps.
        5. After the film is placed for 10-20 hours, there is no change in product quality.
        Extending the life of the laminating machine is mainly for the maintenance of the motor when using it. The main points to pay attention to are the following:
        1. Clean up debris, dirt on the motor, nearby debris, and stay away from flammable and explosive materials.
        2. Before starting, you should check whether the machine rotates smoothly, whether it is blocked, and whether the belt connection is normal; if there is any abnormality, you should never continue to start the glue machine.
        3. The voltage at start-up should meet the rated voltage; the general voltage value is about 5 to 10 percent of the rated voltage value.
        4. After the motor fails, you must cut off the power supply and can not continue to use; you should find a professional to repair.
        As long as the life of the laminator is maintained, correct operation, maintenance, and maintenance; other parts also need to be well maintained; careful maintenance and maintenance are a good way to extend the life of the machine.

        The laminating machine uses a hot laminating process, which should be used in conjunction with the hot laminating film. After laminating, the paper and the film are combined into one. The laminating machine uses varnish. A film coating machine refers to a machine that applies a solid continuous film formed by applying one or more coatings on a substrate.
        Lamination: also known as "over-plastic", "laminating", "sticking film", etc., refers to the transparent plastic film is applied to the surface of the printed matter by hot pressing, which protects and increases the gloss. Lamination has been widely used in book covers, picture albums, commemorative albums, postcards, product manuals, calendars and maps for surface binding and protection. At present, the common film packaging products are carton, carton, tote bag, fertilizer bag, seed bag, sticker, etc.
        Coating film: also known as paint film. A solid continuous film formed by one or more coats of paint applied to a substrate. Generally, the coating film is composed of multiple coatings, and the amount of coating is determined according to the requirements of the object to be coated. Generally includes a primer layer, intermediate coating and topcoat layer. The coating film reflects the effect of supporting use of the paint.
        Laminating film: Weaving warp cloth made of polypropylene or low-pressure polyethylene, treated with a special process, and then covering the surface with a layer of high-pressure polyethylene electrostatic film with a thickness of only 0.04 cm, it becomes a laminating film. Its thickness is only 0.2 ~ 0.24 cm, the weight per square meter is only 160 grams, less than 1/10 of the weight of the general cotton yarn sail tarpaulin, but its vertical and horizontal tensile strength can reach up to 120 kg, and the temperature resistance capacity is from 70 ℃ to minus 40 ℃, and tasteless, non-toxic, wear-resistant and rub-resistant, can be used for a long time in various ecological or physical and chemical environments such as infrared, ultraviolet, laser, wind, frost, rain, snow, acid and alkali.

         When plastic products make people's lives more convenient, it means that we can't have good products without plastics, but in recent years, the toxicity of plastic products is controversial, but if we replace plastic materials, I believe that in the future Year is a very arduous task to improve plastic products. Insufficient quantity of plastic products, scientific use is king.
        Laminating machine equipment: roller coating glue after drying, using special equipment pressure and printing of composite material parts. That is, the laminating machine has both automatic and semi-automatic machines. In different types of structure models, the coating technology has its own uniqueness, but their basic structure and working principle are the same, mainly by tape, glue coating, drying, composite materials, winding five parts and mechanical transmission, automatic tension Control, automatic deviation correction and other unwinding devices.
        There are 5 advantages of the laminating machine to replace the traditional film. It is an inevitable trend for the laminating film to replace the laminating film.
         1. The traditional film-covering door is cheap, each machine has only one thousand or two thousand yuan, but the cost is too high. The membrane liquid of the laminating machine is only 0.3-0.4 yuan per square meter. 10 times the cost savings. The one-year price difference of the laminating machine will save the long-term use of coating and laminating equipment.
        2. The laminating machine has low laminating efficiency and slow speed. The coating machine is 300 square meters per hour.
        3. Good quality. The plastic film cover layer can separate the layers. The laminator does not.
        4. High hardness, wear resistance, oxidation resistance and yellowing resistance. Take photos as an example. The lamination machine will produce a lot of scratches from the short flow distance from production to the customer's hands after lamination. There is a chance of coating, and it can be stored for a long time without discoloration.
        5. Easy to use. It is a laminating machine with a small footprint. The civil 220V power supply is connected with a built-in small pump, which can automatically circulate. Here are photos, business cards, menus and some printed advertising products. At the exit is a perfect product.

        The state has issued a series of policies to rectify the heavily polluted printing industry, paper industry and other fields, causing many factories to close and close, resulting in increased costs, reduced competition pressure, and the application of negative pressure laminators has also begun to become widespread.
        What is a negative pressure laminator? It is to apply a plastic film with an adhesive, and then combine it with the printed matter using paper as a substrate, pressurized by a rubber roller and a heated roller, and form a paper-plastic integration product. The products made in this way not only improve the gloss and fastness of the printed matter, and prolong the service life of the printed matter, but at the same time, the plastic film also plays a protective role in waterproof, anti-fouling, abrasion resistance, and chemical resistance.
        What are its mechanical functions?
        1. Equipped with a non-stop paper feeding device to ensure continuous production;
        2. The use of large-diameter pressing rollers effectively improves the production speed and ensures that the composite products are flat and bright;
        3. A powder removal mechanism combining powder sweeping and powder pressing is adopted to ensure the powder removal effect;
        4. The advanced drying tunnel structure ensures that the glue on the film can be dried quickly;
        5. Adjustable speed disc-type rotary cutter to ensure the slitting of paper;
        6. The motor adopts frequency conversion control, safe and reliable.
        The above is my brief introduction to the mechanical function of the negative pressure laminator.
