Wrinkle phenomenon of laminating machine in laminating machine, in fact, this kind of problem is widespread, and because of this, the problem of wrinkling of laminating machine of laminating machine has also been a problem that has been discussed in the post-press processing industry. The solution to the wrinkle of the laminating machine of the laminating machine is that the operation of the pre-coating laminating machine is much simpler than the previous coating film laminating machine. It also has the functions of automatic drawing and backing.
        That is, the causes and solutions of wrinkles on the coating film laminator are as follows.
        1. Vertical wrinkles. The tension of the film is too large, the pressure is not flattened, and there are creases in itself, so it wrinkles after the film is covered.
        Solution: Relax the tension of the film, adjust the stretching roller, and then flatten the film before pressing.
        2. Wrinkled diagonally. The film has a large pulling force and improper adjustment of the roller position, which causes the film to be inconsistent in tension and uneven in film transfer, and is regularly folded toward the loose side.
        Solution: Relax the tension of the film, adjust the stretch roller or temporarily change the film.
        3. Horizontal wrinkles. The temperature of the heating roller is too high, and the pressure of the rubber roller is too large. During the compounding, the film is scalded in the horizontal direction into a horizontal wrinkle.
        Solution: appropriately reduce the temperature of the roller or reduce the pressure of the rubber roller.
        4. When the temperature is too high during heating, the film is deformed and wrinkled.
        Solution: lower the temperature.
        5. The water content in the paper is too large, the paper shrinks after the film is dried, and the film deforms and wrinkles.
        Solution "The moisture content of the paper should be about 5% to keep the temperature and humidity in the working room normal.
        6. The conduction roller of the laminating machine is not running well or there are dirt on the surface, which makes the film unable to stretch and operate normally.
        Solution: Conductor roller bearings should be lubricated on time and kept clean and free of foreign objects.
        7. The gap between the guide rollers is too small, squeeze the film into a wrinkle before pressing.
        Solution: Correctly adjust the gap between the guide rollers.
        8. The temperature of the roller is too high and the film expands when heated.
        Solution: Reduce the roller temperature.
        9. The film conducting rollers are not parallel, causing the film to run unbalanced.
       Solution: Correctly adjust the conduction roller to be parallel.
       10. The ends of the film are inconsistent or have wavy edges.
       Solution: replace qualified film.
       11. The adhesive layer is too thick, the viscosity is too large, and the paper and film slide after being pressed and pressed.
        Solution: adjust the amount of glue and increase the drying temperature.
        The coating principle of the pre-coating film laminating machine is similar to that of the instant coating film laminating machine, that is, the coating process and process are more simplified, and the adhesive is not required to heat and dry. I believe that it is more convenient for everyone to use when laminating.

        Laminating machine / laminating machine The laminating film is divided into two categories according to different equipments and processes, one is "that is, coating film"; the other is "pre-coating film", which is divided into two kinds of film and sub-film.
        Instant-coated film is a process that uses instant-coated film machine to immediately stick film with glue to carry out paper-plastic compounding. It mainly consists of a coating film processing plant or a processing workshop, where the roll plastic film is coated with an adhesive as required, dried (slightly) compounded, and after pressure, the paper film is adhered together to form a coated product.
        That is, there are two types of coating equipment, automatic and semi-automatic, and the basic working principle is the same. The technological process mainly includes unwinding → sizing and coating → drying → compounding → slitting → finished product accumulation.

        The laminating machine and the fully automatic laminating machine combine the pre-coated film and the printed matter using paper as the substrate after being pressed by the rubber roller and the heating roller 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 three factors: temperature, pressure and speed, so it is correct Dealing with the relationship between the three is very important 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.

        Laminating machine is often used in life. Laminating is to apply adhesive to the plastic film and combine it with the printed matter that uses paper as the substrate. After being pressed together by the rubber roller and heating roller, the paper is formed One product.
        We need to pay attention to the following issues when operating the laminating machine:
        1. There are two kinds of films used in laminating machine and automatic laminating machine: sub-film and bright film. The effect of sub-film is like matte, which has more grades. The effect of bright film is obvious and intuitive, and it has a reflective effect. Choosing different membranes has different effects, which should be freely selected according to your needs.
        2. There are different types of laminating machines, including automatic laminating machines, small laminating machines, pearl cotton laminating machines, pre-coating laminating machines, etc., which should be selected according to production needs.
        3. The laminating machine is best to laminating on both sides at the same time, so that it looks more smooth, has stiffness, and does not curl.

        The conventional automatic laminating machine technology on the market adopts the method of laminating with glue, and the automatic laminating method of the automatic laminating machine is different. The PE film with high pressure polyethylene as the main material is used. After the special treatment of the film is stopped, the PE film can be hot-melted on the color printing paper. After being processed by the automatic laminating machine, it will not bubble when it is rubbed hard, and can withstand high temperatures of about 20 to 120 degrees. In the process of non-glue automatic laminating, a layer of auxiliary materials is placed between the heating roller and the PE film, and passes through the automatic laminating machine together, and then the automatic laminating products are removed from the auxiliary materials. Due to the different materials used, the same kind of PE film can make light film, matt or other effects. First of all, high-pressure polyethylene blow molding PE film as the main material, that is because of its easy to obtain hot melt and plasticity.
        The advantages of fully automatic laminating technology are obvious
        First, if he does not use glue, the cost will be reduced a lot, and it is obviously reduced. Especially for the matt film and the laser film, the cost is basically reduced by about 10%.
        The second is that he is absolutely safe and environmentally friendly. In the past, those easily volatile harmful gases were very harmful to the human body during use. At the same time, after experiments, the product was placed in a 5% caustic soda solution at 80 ° C. With light agitation, the self-adhesive indentation will show the phenomenon of separation of the film and the paper. The film floats up and the paper sinks, which is easy to recycle.
        Third, due to the automatic laminating of the glue, the glue layer is 0.002 ～ 0.003mm after the initial drying, so the powder on the printing paper will appear to be uncompressed, and the product will be uncompacted. snowflake". But the automatic lamination without glue will not, because the film used in this technology is 0.017 ~ 0.02mm thick, and it becomes this thickness of glue in its hot melt state, so it can be used casually with less than half the pressure. No "snowflake" is produced, so there is no need to dust.
