The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. It is a kind of special equipment for paper, board and film laminating. It is combined with rubber roller and heating roller to form a product of paper and plastic.
        1. The machine does not start: the input wire is disconnected, the power cord is reversed, and the voltage is insufficient.
        Second, the temperature measurement is not accurate: thermocouple, temperature controller. Whether it is installed incorrectly and damaged.
        3. The working vacuum does not come up: the gas path is blocked, the hand valve or the solenoid valve is not closed, the vacuum pump motor belt is loose, and the vacuum gauge is damaged.
        4. The main power switch trips: leakage of the input wire on the top of the heating box, leakage of the distribution box, external wires on the equipment, leakage of the motor, etc.
        Fifth, the suction film is not in place: the vacuum is not enough, the air leakage, the temperature is not enough, the film is too thin, the workpiece is pasted with other materials, the concave depth of the workpiece exceeds the lift of the film, the suction time is too short, the film is not lifted, the distance between the workpiece Too close.
        Sixth, the surface of the overlaid workpiece has folds and is not smooth or the corners cannot be wrapped: the film is not straightened, the quality of the film is not good, the workpiece is not well polished, the glue is sprayed too much, and the mold below the workpiece is too low.
        7. Breaking phenomenon: the temperature is too high, the heating time is too long, the film quality is not good, and there is no heating.
        Eight, bad sticking situation
        1. Improper selection of adhesive, improper setting of glue amount, incorrect proportioning measurement. The type and amount of adhesive should be reselected.
        2. The diluent contains alcohol and water that consume NCO groups, so that the hydroxyl group of the main agent does not react. High-purity ethyl acetate should be used.
        3. There is powder spraying on the surface of the printed matter. Wipe gently with a dry cloth.
        4. The ink layer of the printed matter is too thick. Adhesive coating arrangement should be increased to increase pressure
        5. The ink layer of the printed matter is not dry or completely dried. It should be hot pressed once before gluing; choose an adhesive with high solid content; increase the thickness of the adhesive coating; increase the temperature of the drying tunnel, etc.
        6. The adhesive is absorbed by the printing ink and paper, which makes the coating amount insufficient. Should re-formulate and set the coating amount.
        7. The surface treatment of plastic film is not enough or exceeds the applicable period, which makes the treatment surface invalid. The plastic film should be replaced.
        8. The pressure is low, the speed is fast, and the temperature is low. The temperature and pressure of the film should be increased, and the vehicle speed should be appropriately reduced.
        9. Foaming
        1. The printing ink layer is not dry. It should be hot pressed again and then glued; postpone the coating time and let it dry completely.
        2. The printing ink layer is too thick. Should increase the amount of adhesive coating, increase pressure and compound temperature.
        3. The drying temperature is too high, and the surface of the adhesive skins. The drying temperature should be reduced
        4. The surface temperature of the composite roller is too high. The temperature of the composite roller should be reduced.
        5. The film is wrinkled or loose, and the film is uneven or curled. The film should be replaced and the tension adjusted.
        6. There are dust impurities on the surface of the film. It should be cleared in time.
        7. Uneven coating of adhesive and low dosage. The coating amount and uniformity should be improved.
        8. The adhesive concentration is too high, the viscosity is large, and the coating is uneven. Use thinner to reduce adhesive concentration.
        10. Laminating machine wrinkling
        1. The film transfer roller is unbalanced. The transfer stick should be adjusted.
        2. The ends of the film are inconsistent or wavy. Qualified film should be replaced.
        3. The adhesive layer is too thick, the solvent is not evaporated completely, which affects the viscosity. When pressed by the pressure roller, the paper and the film slide. The amount of glue should be adjusted to increase the temperature of the drying tunnel.
        4. Both ends of the electric heating roller and the rubber roller are unbalanced, the pressure is inconsistent, and the linear speed is not equal. Two rollers should be adjusted.

        When choosing a laminating machine (peritoneal machine) machine, many customers want to buy a specialized laminating machine. It is best to use a laminating machine to package all their products. This idea is understandable, but it is not desirable. . At present, there are many types of laminating machines on the market, which are dizzying. Customers have a sense of discomfort when choosing laminating machines. Can't help but ask: How can I buy a laminating machine that suits me?
        Because there are many types and models of laminating machines on the market, it is easy to cause confusion when buying, and there is no choice.
        The size, function, characteristics, price and brand of the laminating machine will be different. You can choose a new laminator, or you can buy a second-hand laminator with good performance. Relatively speaking, buying a new laminator is guaranteed both in terms of performance and after-sales. Rest assured.
        1. Tape laminating machine
        The most commonly used laminating machines for homes and small businesses use adhesive tape. This type is very effective and the price is not expensive. The adhesive tape is used to heat and press the plastic document or photo.
        2. Oil temperature hydraulic glue-free peritoneal machine
        The heated rubber roller uses heated melted glue on the laminated film, and then uses the roller to apply it to paper or cards. The use of rollers means that the adhesive can be distributed more evenly, reducing the risk of air bubbles on the laminate. Laminating machine rolls can be used for large-size lamination, often used in the printing industry to laminate posters, magazines, postcards and books. This type of laminating machine is also widely used in houses, offices and schools. If the content to be coated is easily damaged by heat, cold-rolled rubber rollers can be used.
        3. Document laminating machine
        These machines are dedicated to plastic documents. Before the document laminating machine was born, it was necessary to use plastic bags or plastic bags to seal the documents, and the bubbles generated would make the contents of the documents difficult to read. The document laminating machine solves this technical problem. The ID laminator can also punch holes in the ID, put on a rope and hang it around the neck. Some document laminating machines have laser visible imaging, ultraviolet color, and nano text to prevent forgery.
        Fourth, low-cost second-hand laminating machine
        If you have insufficient funds, you can buy a second-hand laminator. Sometimes, choose A4 laminator. Or self-sealing laminating machine.
        These are models of laminators that can be selected, it is necessary to do some investigations before purchasing, and purchase the appropriate model according to actual needs.
        Summary: Now the society is developing rapidly, the products are extremely rich, all kinds of commodities need to be packaged, so the development of laminating machinery has been born.

        After the small laminating machine is adjusted, the pre-processed printed matter is sent to the paper feeding mechanism for laminating, and samples are taken for inspection. Use a small amount of printed matter to inspect before laminating, so as not to cause a lot of waste. After passing the inspection, mass production can be carried out. The method of using the film inspection is as follows:
        1. Tear off the corner of the proof sheet completed by the lamination in the width direction, press and hold the paper, and tear it all in the width direction. After tearing off all the tears, if the graphic imprint on the surface of the printed matter follows the glue layer and the fiber of the paper Transferred to the film, it means that the printed matter and the film adhere well, and it is a qualified product.
        2. Put the film-coated sample into the drying tunnel and bake at 60-65 degrees Celsius for about 30 minutes. If there is no blistering, no delamination and no wrinkles will occur, and it is a qualified product. After baking, the tear film should not be separated from the paper intact.
         3. Immerse the sample in cold water for 1 hour and take it out. If the plastic film is not separated from the printed product, it is a qualified product.
        4. Put the sample on the creasing machine and apply pressure. If the pressed uneven part does not delaminate, it is a qualified product.
        In summary, after one or more inspection methods meet the requirements of the sample of the small laminator, it can be put into mass production. If it does not meet the requirements, the sample fails, the pressure adjustment process is retested, until the inspection is qualified.
        Application range of small laminating machine
        1. Scope of processing: Use PVC cladding panel furniture, speakers, cabinets, craft doors, anti-theft doors, molded doors, panel door covers, decorative wall skirt boards, etc.
        Second, the range of substrates used: medium and high density fiberboard, plywood, solid wood board, metal board, gypsum board, magnesite board, etc.
        3. Equipment characteristics:
        1. Using digital display automatic control technology, easy operation and high degree of automation.
        2. Adopt vacuum technology to double air passage, stable air performance, high workpiece yield.
        3. The working table adopts frame steel frame structure, which effectively improves the vacuum degree and is durable. The exchangeable workbench can carry out a box of multiple pieces of veneer, so that one machine can be used for multiple purposes.
        4. A unique far infrared constant temperature heating system is adopted to save energy, time and electricity. Heating is uniform, thereby reducing the deformation, wrinkling, degumming and other phenomena of the product.
        5. The key components of the electronic control system are configured with high temperature resistance and high insulation materials, and the operation is safe and reliable.

        The laminating machine is a kind of product in which a plastic film is coated with an adhesive and printed with paper as a substrate after being pressed by a rubber roller and a heating roller to form a paper-plastic product. The classification can be divided into coating laminating machine and pre-coating laminating machine. The printed product after the coating has a thin and transparent plastic film on the surface. Fastness has prolonged the service life of printed matter, so how can the amount of film be reduced when laminating? Let Xiaobian introduce it to you.
        The amount of film used by the film laminating machine is mainly related to the operation level, so it is generally recommended to:
        1. 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.
        2. Be sure to wait for the blot to dry before coating, otherwise it will cause blistering or hair pulling.
        3. Spray as little powder as possible during printing, otherwise it will cause emptying and bubbling at the powder pile. 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.
        4. Check the photo paper is clean before laminating, laminating the film in a clean environment.
        5. When laminating, attention should also be paid to the direction of the paper strands, especially thick paper, to reduce the curling of the paper due to rolling and stretching.
        The above is the relevant introduction to the recommendations for reducing the amount of film used when laminating the film. I hope it will help you

        What faults will occur in the normal operation of the vacuum laminator, how to eliminate it?
        In recent years, the pollution of the laminating machine has been effectively controlled, which deserves a good extensive evaluation by the industry. What kind of environment is the vacuum laminating machine completed? It is a film that is vacuumed between the film and the painting and is stable under certain conditions.
        However, the complexity of its operation makes the cost high and the quality has certain limitations. Then what kind of failures will occur in the usual operation, how to eliminate it?
        First, the machine does not start because the voltage is not enough, the input wires are different, and the power cord is reversed;
        Second, if the installation is incorrect, it will cause inaccurate temperature measurement;
        Third, the failure of the gas circuit will cause damage to the vacuum gauge;
        Fourth, the total power supply will often have leakage, tripping and other phenomena, which have certain hidden dangers;
        Fifth, if the degree of vacuum does not meet the requirements, not only air leakage will also cause problems in the quality of the membrane;
        Sixth, the production process must ensure that the surface is smooth and polished in place, otherwise there will be film quality problems;
        Seventh, we must always pay attention to whether the hand valve is opened, so that it will not pull down when the film is covered;
        Eighth, the heating temperature should not be too high, it will cause the phenomenon of breaking.
        With the development of woodworking machinery enterprises, vacuum laminating machines are more and more applied to this industry. Next, I will teach you how to operate vacuum laminating machines correctly!
        1. Check whether the pressing device and the rotating parts are in good condition before going to work.
        2. Clean up the dust and scum in the workbench.
        3. Prepare necessary product pads (6-8 mm smaller than the workpiece) and other necessary materials.
        4. The vacuum laminating machine checks and adjusts the temperature and schedule setting values ​​according to the thickness of the film material.
        5. When processing multiple pieces together, the appropriate distance should be placed according to the thickness of the processed board (generally 3-4 times the thickness of the board).
        6. Before starting the heating hood, check whether the clamping frame is locked, whether there are objects and personnel hands on and around the guide rail.
        7. During the operation of the vacuum laminator machine, it is strictly forbidden to stand around the machine, let alone put the hand on the guide rail and equipment, to prevent the machine from automatically returning to the heating cover to hurt people.
        8. It is strictly forbidden to place products and other objects on the heating hood.
        9. Turn off the power immediately when the machine is found to be abnormal, and notify the supervisor
        10. Do not disassemble safety and other protective items at will.
        11. The operator must not leave the machine during work.
        12. Turn off the power when the work is completed. The above is the operation procedure of vacuum laminator. Everyone must operate according to the correct method and regulations, otherwise there will be danger.
