The pre-coated film laminating machine is a special equipment for compounding printed materials with pre-coated plastic. Compared with the instant coating laminator, the biggest feature is that there is no sizing and drying parts, so this type of laminator is compact in structure, small in size, low in cost, easy to operate, and has good product quality stability.
        The operation of the pre-coating film laminating machine includes three parts: gluing, drying and hot pressing. The operation is higher, and the advantage is that the quality of the finished product is reliable.
        The principle of pre-coating film laminating machine:
        (1) Using instant film as the cover can protect the paper. After the film is coated, the service life of the cover (or the surface of the printed product) can be extended, especially for the students' textbooks, so the amount is increasing.
        (2) Imprints are not easily destroyed. After being coated with a pre-coated film, it can increase the color effect and protect the color printed graphics without being worn. This is conducive to the publishing house editors to make various art designs on the cover or printed surface according to their needs, so it also promotes the increase in usage.
        (3) The production of coating film is beneficial. The production cost of the coating film in the coating is low, easy to start, and profitable, and the enterprise can benefit.
        1. Structure and configuration points of pre-coating film laminating machine
        2. Compared with the traditional laminating machine, the glue-free laminating machine does not need a glue unit, which saves the process and is economical and environmentally friendly; it does not require a drying tunnel, saving electricity and space.
        3. No glue film, pre-coated film dual-purpose machine.
        4. The heating roller is installed in the heating roller, and filled with heat conduction oil to make the temperature of the roller uniform and stable.
        Manual type: manual paper feeding, automatic film lamination, automatic winding. After automatic winding, you can choose manual slitting or automatic slitting on the slitting machine.

        The pre-coating laminating machine is a special equipment that combines printed materials with pre-coated plastic films. The main structure is composed of four parts: film unwinding, automatic input of printed materials, hot-press laminating, and automatic rewinding. Compared with the film machine, there is no need for adhesive coating and drying parts, so the structure is compact, small in size, low in cost, easy to operate, easy to use when starting, large production flexibility and high efficiency. The compounding of the pre-coated film and the paper printed matter only needs to be hot pressed. It is suitable for all kinds of laminating machines, laminating machines and plastic sealing machines with hot pressing function. No need to make any changes to the bridge type combination laminating machine of the glue-coated wet composite process, it can be completely coated with pre-coated film.
        1. The automatic conveying mechanism of the printed product input part of the pre-coated laminating machine can ensure that the printed products do not overlap during the transmission and enter the composite part at an equal distance. Generally, pneumatic or friction mode is used to achieve control. The printed matter can also meet the above requirements.
        2. The composite part of the pre-coating laminator includes a composite roller group and a calender roller group. The compound roller group is composed of heating pressure roller and silicone pressure roller. The hot pressure roller is a hollow roller, which is equipped with a heating device inside, and the surface is forged with hard chrome, and is polished and refined. The temperature of the hot roller is tracked by the sensor and corrected by the computer at any time. The compound pressure is adjusted by an eccentric cam mechanism Stepless adjustment. The calender roller group is basically the same as the composite roller group, that is, it is composed of a chrome-plated pressure roller and a silicone pressure roller, but without a heating device. The main function of the calender roller group of the pre-coating laminator is: after the pre-coated plastic film is combined with the printed matter by the composite roller group, the surface brightness is not high, and then the secondary extrusion of the calender roller group, the surface brightness and adhesion The intensity is greatly improved.
        3. Transmission system The transmission system is driven by a high-power motor controlled by a computer. After one-stage gear reduction, it is driven by a three-stage chain to drive the movement of the paper feed mechanism and the rotation of the silicone pressure roller of the composite part and the calendering mechanism. The pressure roller set maintains a suitable working pressure under the action of steplessly adjusted pressure.
        4. Computer control system The computer control system uses a microprocessor. The hardware configuration consists of a main board, digital key board, optical isolation board, power board, stepper motor power driver board, etc.

        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.
