The laminating machine is a machine that attaches a layer of protective film to photo paper card photos, etc. There are two types of laminating machines, one is a cold laminating machine, and the other is a hot laminating machine. It can be covered with hot laminating film or cold laminating film, and the operation is also convenient.
        1. Introduction of Laminating Machine
        The laminating machine can be divided into two categories: instant coating laminating machine and pre-coating laminating machine. It is a special equipment for paper and film. Instant coating laminating machine includes three parts: gluing, drying and hot pressing. It has a wide range of application and stable and reliable processing performance. It is currently widely used in China. Pre-coating laminating machine, no gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for laminating processing of large batches of printed products, but also suitable for laminating small batches and scattered printed products such as automated desktop office systems Processing is very promising.
        2. Introduction of cold laminating machine
        Cold laminator (Laminator machine), also known as laminating machine, laminating machine, is an indispensable auxiliary equipment for the production of photo advertisements. At present, there are two types of cold laminators on the market: electric cold laminator and manual cold laminator. Cold mounting actually puts a layer of cold mounting film on the pictures and photos. If it is a small photo or picture, the cold lamination film can be pasted by hand. However, if the object to be coated is large, blistering will occur and the film is not strong, etc., so it is necessary to use a cold laminator to achieve it. In fact, the cold laminating machine is a device that overlays the cold laminating film on the photos or pictures. A good cold laminator should be non-foaming, can mount long pictures, and have a long service life. The cold-mounted pictures and photos can not only prevent wear, but also waterproof, especially in outdoor advertising has a very wide range of applications.
        3. The difference between laminating machine and cold laminating machine
        The laminating machine is a machine that attaches a layer of protective film to photo paper card photos, etc. The laminating machine is divided into two categories, one is cold laminating laminating machine (also called cold laminating machine), and the other is hot laminating. Laminating machine. Therefore, the laminator includes a cold laminator, and the laminator is a larger concept.

        After the modification of the laminating machine, the stability and followability of the system have been greatly improved, the problems of reverse osmosis membrane jitter and scratches have been completely resolved, and the product quality has been greatly improved. The composite reverse osmosis membrane is a new type of polymer material, and the membrane laminator is the key production equipment. There are many problems with the electrical control system of the imported laminator, which cannot guarantee the quality of the product. The overall scheme design for the transformation of the electrical control system of the laminator. The PLC with simple programming and easy maintenance is used to replace the industrial computer, and the inverter is used to replace the imported DC speed regulating device with poor reliability. Only when the tension of each section of the reverse osmosis membrane is kept constant during the operation of the equipment can the quality of the reverse osmosis membrane be ensured.
        The control system uses a touch screen as the man-machine interface. The screen of the man-machine interface makes the operation more intuitive and convenient. According to the prompts of the man-machine interface, the problems in the system can be quickly found. The unwinding adopts tension feedback and magnetic powder clutch control, which has a good tension following effect, and the tension will not change with the change of the roll diameter. The intermediate traction motor uses constant tension control, and the motor that provides the reference speed uses speed closed-loop feedback. The encoder and the high-speed counter of the PLC are used to measure the speed feedback value, and the PID calculation is implemented by the PLC. The tension of the middle section adopts a scheme combining feedforward control and tension feedback control. The feedforward part output by the controller is proportional to the reference speed, and the feedback part is provided by the tension PID controller.

        The laminating process of laminating machine refers to the whole process of laminating pictures and photos, including film selection, film making, and cutting. Mainly used for post-production of advertising pictures and wedding photos. The pictures covered with film have high anti-corrosion, waterproof, dustproof, anti-wrinkle and anti-ultraviolet erosion performance, which can produce strong three-dimensional sense and artistic appeal. The cold laminating machine is the main equipment to complete the laminating, and it is also the necessary supporting equipment for the computer inkjet machine and electrostatic photo machine. At present, the commonly used equipments for laminating are manual cold laminator, electric cold laminator, self-exposed film cold laminator and automatic cold and hot laminator. There are also transfer equipment.
        The effect of the laminating process of the laminating machine:
        1. Overlay 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 keep the bright color of the picture screen enduring, Extend the life of picture display.
        3. Paste the picture on the display board or fabric to make a hanging advertising picture.
        4. Press a special mask or sheet on the picture to form a picture with special artistic effects such as bright light, matt, oil painting, virtual and three-dimensional.

        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.

        Now the laminating machine is already a necessary equipment in the advertising industry, and everyone must know its major utility. The film is divided into cold film and hot film. The cold film itself is sticky and can be directly bonded to the material; while the hot film itself is not sticky and needs to be melted by heating to bond to the material. The manual cold laminator is very suitable for the small advertising companies with small business volume, which can not only realize lamination, but also save costs. Small investment can achieve big benefits. Jintu wide-width multi-functional cold laminating film machine has three different sizes to choose from, the width of the film is 1600mm, 1300mm and 1100mm, to meet your different size needs. The maximum film thickness reaches 25mm, which is superior to other machines in the industry.
        Analysis of the causes of wrinkling of laminating film on graphic laminating machine and key points of laminating machine operation
        1. Analysis of the causes of wrinkling of mounting film
        (1) The raw material has a high degree of tightness on one side or a loose middle between the two sides, causing unevenness of the paper surface and causing wrinkling of the mounting film.
        (2) The poor temperature resistance of the raw materials causes deformation after entering the oven and causes the mounting film to wrinkle.
        (3) The quality of the laminating machine is different, and the laminating film with a poor laminating machine causes the laminating film to wrinkle.
        (4) The laminating staff's poor operation skills or improper operation directly cause the laminating film to wrinkle.
         2. Key points of operation of laminating machine
        (1) Install the laminating machine on a special bracket and place it on a stable and firm workbench. Then make a special platform for laminating film, the height is 5 mm lower than the edge height of the laminating machine, the width is 1600 mm, and the length is more than 1 meter.
        (2) Place the material to be mounted on the laminating machine or the empty laminating machine on the iron roller in front of the laminating machine. After entering the laminating machine, the coating surface should face upward.
        (3) Adjust the pressure adjusting hand wheel on the laminating machine, lift the upper rubber roller, and then pass the material out of the two rubber rollers of the laminating machine by 10 cm.
        (4) If laminating film is needed, the cold laminating film needs to pass through 10 cm of the two rubber rollers of the laminating machine and be placed on top of the consumables. The PVC film is super-oriented.
        (5) Adjust the position of the consumables on the platform so that the tightness of the two ends of the laminating machine is basically the same, and then adjust the pressure hand wheel on the laminating machine, lower the top roller and adjust it to the empty position. The pressure on both ends must be the same.
        (6) If it is an empty film laminating machine, you can shake the hand wheel to move the consumables forward. When shaking, it must be uniform, and the moving speed should be the same, not when it is fast or slow. If there is no wrinkle after 5 meters, it means there is no quality problem of consumables.
        (7) If laminating film is required, first fold the cold laminating film release paper inwards to expose the glue surface on the PVC film, then shake the handwheel in the opposite direction, first stick the adhesive surface to the consumables, and then cold laminating Turn the film over to the back of the rubber roller, and slowly release the cold laminating film from the folded place. At this time, turn the rubber roller to rotate it forward, and slowly remove the release paper as the rubber roller rotates, and maintain the tightness of both sides Consistent and certain intensity until the end of cold mounting.
        (8) If the consumables are deviated during empty running or laminating, it indicates that there is a problem with the operation and it has nothing to do with the consumables.
