The automatic laminating machine uses the pre-coated peritoneal technology for laminating, without gluing and drying parts. It has short process flow, compact structure, simple operation, low cost, large production flexibility, no solvent odor, and no environmental pollution. 2. The laminating quality is good. The automatic laminating machine is not only suitable for laminating processing of large batches of printed products, but also suitable for laminating processing of small batches and scattered printed products such as automated desktop office systems. The automatic laminating machine consists of four main parts: unwinding of pre-coated plastic film, automatic input of printed matter, compounding of hot-pressing zone, and automatic rewinding, as well as mechanical transmission, flattening of pre-coated plastic film, vertical and horizontal cutting, computer control system, etc Auxiliary device composition. The automatic laminating mechanism can ensure that the printed products do not overlap and enter the composite part at an equal distance during the transmission. The automatic laminating machine generally uses pneumatic or friction methods to achieve control, and the conveying is accurate and high precision. Can also meet the above requirements.
        The automatic laminating machine is a special one in the laminating process. In addition to the many advantages of the laminating process, it also increases the visibility of the goods in the packaging. The automatic laminating machine has a colorful printing pattern. Embedded with a curvy visual window, it not only makes the packaging more exquisite, but also plays the role of propagating and beautifying the commodity and revealing the value of the commodity.
        1. The difference between the laminating principle of the automatic laminating machine and the general laminating machine is:
        1. It coats the adhesive on the surface of the film, and the automatic laminating machine then covers the film on the surface of the printed product, and then presses it into the finished product;
        2. The special advantage of the pre-coated film of the automatic laminating machine is that it can be automatically sprayed and can be used to dissolve and spray the powder by heating to achieve automatic powder removal.
        The pre-coated film process does not require a binder heating and drying system for the laminating equipment, which is easy to operate and can be used at any time. The production flexibility of the automatic laminating machine is large, and there is no solvent odor and environmental pollution. Avoid bubbles, delamination and other failures, the transparency of its finished products is extremely high.
        Second, the automatic laminating machine needs to pay attention to the following points:
        First, there are two kinds of films used in the automatic laminating machine: sub-film and bright film. The effect of sub-film is more graded like frosted effect. The effect of bright film is obvious and intuitive, with reflective effect. Choosing different membranes has different effects, which should be freely selected according to your needs.
        Second, the laminating machine is best to laminating on both sides at the same time. The automatic laminating machine is more smooth, stiff, and not curled.
        Third, there are different types of automatic laminating machines, such as automatic laminating machines and small laminating machines. The largest laminating machine can be coated with a width of 32cm, and the length is not limited.
        Third, the automatic laminating machine talks about the effect of the laminating process of the automatic laminating machine
        1. Fully automatic laminating machine overlays the protective film on the picture to improve the strength of the picture and the wear resistance of the surface.
        2. Isolate the picture from the outside air to prevent deformation and cracking caused by corrosion, humidity, and drying of corrosive gases in the atmosphere, fading and discoloration caused by rain scouring and ultraviolet radiation, and automatic laminating machine computer bronzing machine to keep the picture The bright color of the picture lasts for a long time, extending the life of the picture display.
        3. Fully automatic laminating machine pastes the pictures on the display board or fabric surface to make a hanging advertising picture
        4. Press a special mask or sheet on the picture, and the automatic laminating machine will form a picture with special artistic effects such as bright light, matt, oil painting, virtual, three-dimensional and so on. The mounting method of the dedicated hot film on the equipment heated to a certain temperature (about 100-180 ° C) is called hot lamination. The automatic laminating machine can be divided into single-sided hot lamination and double-sided hot lamination because of its light Good permeability and water resistance, good heat resistance and strong hardness, suitable for post-production of advertising pictures based on lights or other occasions. Fully automatic laminating machine, but the hot laminating equipment and consumables are more expensive, the operation is complicated, the energy consumption is large, and the cost of the laminating machine is also high.
        Fourth, the technical parameters of the automatic laminating machine, the technology used by the automatic laminating machine is divided into two categories. One is the direct heating from the electric hot plate. It is introduced into the heating zone after the front rubber roller is introduced. The automatic laminating machine then presses and exports. This processing technology is relatively backward. Because the heating and pressurization are carried out in steps, the surface of the processed article is prone to gas saturation and flatness is not good. However, this kind of technology is less difficult, the manufacturing cost is low, the automatic laminating machine and the heat energy loss during the processing are less. The other is that the front guide roller is a hot press roller, which is heated and pressurized synchronously, and then enters the rear rubber roller with cooling and leveling effect to be exported. The method of obtaining heat for the front guide roller of the automatic laminating machine is divided into two types: internal conduction heat type and external radiant heat type. Generally, the main machine and the coil machine adopt the former method. The latter model is adopted for the smaller specifications of the automatic laminating machine. At present, this hot pressing roller technology is relatively advanced. Due to the simultaneous heating and pressurization during the processing process, the bubble problem of the plastic packaged items is eliminated, and the automatic laminating machine also enhances the intuitive effect of the plastic packaged items by cooling and leveling. At present, the production of domestic plastic packaging machines is limited by the technology, process, materials and other conditions.
        Fifth, from the perspective of the development process of the glue technology, due to the improvement of the performance of the automatic laminating machine and the development of various special films, this special processing method will have great development. For example, the application of cloth film, matt film and ultra-low temperature film to improve the artistic effect can improve the artistic effect of the original. The automatic laminating machine has great potential for development. In addition, a newly developed bronzing technology can use a special bronzing film to cover the fonts that need to be processed, and perform bronzing on the prefixes of copies, etc., after the automatic laminating machine is processed by the plastic sealing machine. Achieve the bronzing effect, which makes the original very complicated handling method simple.

        The automatic laminating machine is best to regularly check whether there is glue or grease on the rubber roller, and wipe the rubber trace 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.
        (1) The printing ink layer is not completely dry: hot pressing first and then gluing, can also delay the film date, making it completely dry.
        (2) The printing ink layer is too thick: the amount of adhesive coating can be added properly to increase the pressure and compound temperature.
        (3) The surface temperature of the composite roller is too high: adopt air cooling, closed electric heating wire and other heat dissipation methods to quickly reduce the temperature of the composite roller.
        (4) The dry temperature of the film is too high: if the dry temperature is too high, it will cause the skin of the adhesive to cause blistering problems. At this time, the dry temperature should be properly reduced.
        (5) The reason of the film: blistering problems caused by wrinkled or loose appearance of the film, uneven or curled film, can be dealt with by adjusting the tension size or replacing the qualified film.
        (6) The reason for the concentration of adhesive: high adhesive concentration, high viscosity, uneven coating, and low dosage are also one of the reasons. At this time, thinner should be used to reduce the concentration of adhesive, or appropriately increase the amount of coating And uniformity.

        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.
