The laminating machine is aimed at the surface lamination of printed products, such as books, posters, color box packaging, handbags, etc. In response to the continuous improvement of global environmental awareness, oily lamination will be gradually replaced by water-based lamination.
        (1) Hot pressing roller of laminating machine
        The hot pressing roller is a hollow roller with an electric heating device inside. The temperature of the roller is controlled by sensors and instruments on the console. The surface state and thermal power density of the hot pressing roller have a great influence on the quality of the coated product. The general lamination process requires a hot pressing temperature of 60-80 ° C and an area heat flow of 2.5-4.5W / cm2.
         (2) Rubber pressure roller of laminating machine
         The laminating machine presses the coated product to the hot pressing roller with a certain pressure to make it solidify and stick firmly. The contact pressure during compounding is closely related to the adhesive strength and appearance quality, and is generally 15.0 to 25.0 mPa. Rubber pressure rollers work under high temperature for a long time, but also to keep the roller surface smooth, smooth, small lateral deformation, good tear resistance and peelability, so silicone rubber with better tear resistance is mostly used.
        (3) Pressure adjustment mechanism of laminating machine
        It is used to adjust the pressure between the heat pressure roller and the rubber pressure roller. The pressure adjustment mechanism can use simple eccentric mechanism, eccentric cam mechanism, screw rod, nut mechanism, etc .; Adopt liquid (gas) pressure type pressure adjustment mechanism.

        The pre-coating laminating machine is a special equipment that combines printed materials with pre-coated plastic films. It consists of four main parts: pre-coated plastic film unwinding, automatic input of printed materials, hot-press laminating, and automatic rewinding. It is composed of plastic film flattening, vertical and horizontal slitting, computer control system and other auxiliary devices.
       The pre-coating laminating machine uses the pre-coating peritoneal process for laminating, without gluing and drying parts. It has a short process flow, compact structure, simple operation, low cost, large production flexibility, no solvent odor, and no environment Pollution and good film quality are not only suitable for the processing of large-volume printed products, but also for the processing of small-volume and scattered printed products such as automated desktop office systems.

        In autumn and winter, paper is very susceptible to static electricity, especially in the dry north. For Beijing, due to low indoor air humidity, water molecules are greatly reduced, plus heating, static electricity is very large. The static electricity is easy to attract dust, which will have a great impact on the cold laminating film. Therefore, the laminator machine can be connected to the ground wire and discharge the static electricity with the ground wire. Before live operation, be sure to discharge your hands. You can wear a static wristband or touch other grounded metal objects.
        In addition, we must pay attention to indoor air humidity; some research data shows that when the indoor air humidity is less than 30%, it is conducive to friction and static electricity. If the temperature is increased to 45%, static electricity is difficult to produce. The impact of electrostatic particles on the laminating machine is inevitable, especially the highlighting, but we can still reduce the impact to a minimum. Many fully automatic laminating machines used in large printing plants require the use of professional static elimination such as ion wind bars. Equipment, its strong ion wind removes static electricity and dust on the surface of objects.
        Now there are many PE electrostatic films, PET film electrostatic film uses the principle of electrostatic magnetism to paste PVC film, this is mostly used for anti-counterfeiting printing labels, stickers, barcode stickers, etc., the width of the film is small and it is not suitable for graphics Laminating application. How to eliminate static electricity when laminating the laminating machine, if you have other better methods, then you may wish to share it.

        The laminating machine is divided into hot laminating film machine and cold laminating film machine, so what skills are there in the process of using the cold laminating film machine? Today, the laminating machine manufacturers will analyze the situation with our customers in detail!
        1. The product to be coated must be kept 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 ink to dry before coating, otherwise it will cause blistering or fluffing.
        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 treated. If the number of prints is large, the powder can be hung and hung to remove the powder. If the number of prints is small, the manual stamping machine can be wiped manually.
        4. When laminating, attention should also be paid to the direction of the paper strands, especially thick paper, to reduce the phenomenon that the paper is curled due to rolling and stretching.
        There is also: the temperature is generally controlled to 40 ~ 60 ℃. Too high a temperature will deform the paper and film, causing the product to curl, but not too low, otherwise it will cause insufficient viscosity. The temperature of coated paper should be slightly lower than that of offset paper.

        Analysis of coating and calendering process of glazing machine The glazing process of glazing machine is to coat (or spray, print) a layer of uncoated transparent coating on the surface of the printed matter, after leveling, drying and calendering After that, the technology and method of forming a thin and uniform transparent bright layer on the surface of the printed matter. Correctly understand the importance of glazing equipment structure. The wind blown into the film by the blower of the film laminator blows toward the film and then is discharged from the air outlet. The film laminator divides the drying into a dehumidification zone and a drying zone to improve the drying power level and reduce energy consumption.
        Printing glazing machine glazing is more expensive than laminating machine cladding. The process is simple, in addition to the full version of the glazing, but also requires partial glazing. Composition of UV varnish varnish: Oligomer Oligomer is the most common constituent substance in uv varnish and belongs to a type of film-forming substance. Its performance plays an important role in the curing process and the properties of the cured film. The laminating machine includes a frame and a heating roller, and the film is wound on the heating roller. The portion of the heating roller covered with the film is divided into a dehumidification area and a drying area in sequence, and the drying area is connected to the heat recovery and reuse chamber through.
        The laminating machine includes three parts: gluing, drying and hot pressing. It has a wide range of special applications and stable and reliable processing performance. It is currently widely used in China. The laminating machine has no gluing and drying parts, small size, low cost, flexible and convenient operation, not only the laminating processing of general large-scale printed products, but also the laminating processing of small batches and scattered printed products such as general automated desktop office systems, etc. Very promising.
        The highlights of the laminating machine, namely the coating film:
        (1) The phenomenon of blistering and film stripping is prone to occur. The blistering and film stripping phenomenon is particularly serious in a large-area on-site printing or in a workplace with high humidity.
        ⑵ Occasionally, the surface of the product has different gloss characteristics or fog spots.
        ⑶ The product is prone to curling phenomenon. If the pressure is too large when applying glue or the temperature is too high during drying, this kind of curling phenomenon is more serious.
        ⑷The organic solvent and other chemical substances will be volatilized into the atmosphere when the film is coated by the laminating machine, causing environmental pollution and even causing a fire.
        Seriously affected the R & D and production power level. The new automatic slitting machine is a mechanical device that slits wide-width paper or film into multiple narrow-width materials, and is often used in printing and packaging machinery. The traditional control scheme of the slitter is to use a large motor to drive the rewinding and unwinding shaft. A magnetic powder clutch is added to the rewinding and unwinding shaft, and the resistance generated by the magnetic powder clutch current is controlled to control the surface of the material. tension. The dehumidifying area of ​​the laminating machine includes a blower, an exhaust fan and a dehumidifying chamber. The dehumidifying chamber of the laminating machine is provided with an air inlet, a blower outlet and an air outlet for air circulation in the dehumidifier chamber, the blower opening facing the film.
        The key to the adjustment of the magnetic powder clutch of the new automatic cutting machine The main highlight of the new automatic cutting machine is that the magnetic powder clutch acts as the same resistance device and outputs the same DC voltage through the system control to control the resistance of the magnetic powder clutch. The new automatic cutting machine can be used for stepless speed regulation from zero to synchronous speed, and is specially used for high-speed segment fine-tuning and medium and small efficiency speed regulation systems. The air inlet of the film laminator is connected to the blower, and the exhaust fan is connected to the air outlet. During the drying condition, the film first enters the dehumidification area and then enters the drying area.
