As a common woodworking machine, the vacuum laminating machine has completed the integration of mechanization and modernization in the process of completing the actual laminating, and has also become a very suitable new machine. However, as a consumer unit, in order to choose high-quality and applicable public machine commodities, in addition to thinking about the characteristics of its functions, it also pays great attention to the convenience of its operation and the safety of its use. At the same time that the functions of machines are shaken, the focus on innovation is becoming a subject that professional machine consumption enterprises must face. In the actual consumption of various machines, there is an advanced technical background, innovative strength, and great attention is paid to the intrinsically safe conditions of machine goods.
        In the process of commodity innovation of vacuum laminators, the focus is on automation and intrinsic safety. At present, through the online platform to push product information, on the most professional basis to meet the needs of a wide range of customers. In particular, on the basis that the commercial function design of the vacuum laminator is more applicable, the guarantee of intrinsic safety has also reached a higher professional standard. It can ensure that there are very professional high-quality safety basic conditions, the operation is very convenient and efficient, and the applicability of the vacuum laminator is greatly improved. Regarding consumer companies choosing public machines, the function of vacuum laminators knows that to stop the quality comparison of goods and the function comparison of goods, it is necessary to fully consider the intrinsic safety design standards of the machine itself. Shaking high-quality intrinsically safe machines is the most suitable choice for consumption.

        Vacuum laminating machine has experienced a history of about 20 years in China. It can make all kinds of paper with color printing increase the strength after being laminated by the vacuum laminating machine, and the sense of thickness and texture will occur, which will enhance the "temperament" of the color printing paper, and use this to make various bags, packaging boxes, book covers , Samples and other products. However, the general automatic laminating method uses the method of automatic laminating with glue, such as the use of solvent-based glue, water glue and hot melt adhesive (pre-coated on the film and hot pressing), etc., but the automatic laminating without glue is different. herein.
        First of all, it does not choose the conventional biaxially oriented polypropylene film (OPP), but selects the high-pressure polyethylene blow molding as the main material of the PE film, that is because of its readily available hot melt and plasticity. However, PE film is a kind of material with weak van der Waals force. The waxy additive composition makes a weak interface layer appear on the surface. Therefore, in the hot melt at a lower temperature, its adhesion to paper is also smaller, so this makes this unmodified skill of little value. But when we stop the special strong treatment on one side of the PE film in the future, this scene will be greatly changed. When we use a fully automatic laminating machine to hot-melt PE film on color printing paper, its peel strength has been significantly improved. It can withstand rubbing without foaming, withstand temperature detection of -20 ℃ ～ 120 ℃, withstand rolling, cutting, etc. Suppose we put a layer of auxiliary materials between the hot roller and the PE film to work together. The product and auxiliary materials come out of the machine together, and the products are removed from the auxiliary materials, and waste occurs. Because of the different auxiliary materials, the same PE film can be used to make a variety of fully automatic laminating products such as optical film, matte film, and laser film. And from the visual effect, it is almost inseparable from the OPP automatic laminating with glue.
        Vacuum laminating machines are categorized with different materials and laminating skills that the equipment ends according to the temperature and use of the original materials used.
        Cold mounting: The method of mounting the protective film on the surface of the image by cold pressing at normal temperature is called cold mounting, during which there are single-sided mounting and double-sided mounting, and there are also manual and self-exposed film mounting in the operating method. The cold mounting technique has the characteristics of simple operation, good effect, and low cost. It is widely used in the post-production of advertising light boxes, engineering drawings and wedding photography.
         Vacuum laminating machine hot lamination: The mounting method of special hot film on equipment heated to a certain temperature (about 100-180 ° C) is called hot lamination, which can be divided into single-sided hot lamination and double-sided hot lamination. Its light permeability and water resistance are good, and its hardness is strong, which is suitable for the post-production of advertising images in other occasions. However, hot mounting equipment and consumables are more expensive, messy in operation, large in energy consumption, and expensive. Use a special automatic laminating machine to vacuum the film and draw it, and set it at a certain temperature to finish the laminating. Its operation method is messy, the cost is large and the picture specification is subject to certain restrictions, but the mounting quality is very high. The picture has a strong texture and is suitable for photos.

        The laminating machine is a kind of product in which a plastic film is coated with an adhesive and printed with paper as a substrate after being pressed by a rubber roller and a heating roller to form a paper-plastic product. The classification can be divided into coating laminating machine and pre-coating laminating machine. The printed product after the coating has a thin and transparent plastic film on the surface, the surface is smoother and brighter, which not only improves the glossiness of the printed product and Fastness has prolonged the service life of printed matter, so how can the amount of film be reduced when laminating? Let Xiaobian introduce it to you.
        The amount of film used by the film laminating machine is mainly related to the operation level, so it is generally recommended to:
        1. The product to be constructed must be 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 blot to dry before coating, otherwise it will cause blistering or hair pulling.
        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 disposed of. If the number of prints is large, the powder can be hung to dry, and if the number of prints is small, the powder can be manually wiped.
        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.
        The above is the relevant introduction to the recommendations for reducing the amount of film used in the laminating machine. I hope it will help you.

        Concerning the maintenance of the vacuum laminator, there is a variety of opinions, and we will briefly introduce the maintenance methods. Any machine equipment needs to be regularly inspected, especially the parts of the vacuum laminator. We need to regularly check whether there is damage. If any damage is found It is necessary to replace the new parts immediately; it is also very important for the cleaning of the machine. It is not allowed to be surrounded by people during the operation of the machine, and it is not possible to put debris on the equipment. This is also to prevent the machine from automatically returning to the heating hood. Human approach.
        The last point is to operate in accordance with the instruction manual, and prohibit incorrect operation, so as not to cause greater losses to the machine.
        For personal safety and product safety, everyone should follow the correct method and procedures when using any product to avoid unnecessary accidents. The company here explains the main points of the correct operation of the vacuum laminator.
        First of all, we must ensure that the rotating parts of the pressing device are not damaged, and we must clean the work table frequently without dust, and prepare necessary items, such as product pads. To adjust the temperature of the film from time to time, make sure that the pressing frame is locked when opening the heating hood. There are no objects on or around the guide rails, and the hands of the personnel must be away. It is strictly forbidden to stand around when the laminator is working. If the machine makes an abnormal sound, it should be turned off immediately. The protective items such as safety covers cannot be removed at will. Turn off the power after the final work.

        The pre-coating laminating machine is a special equipment that combines printed materials with pre-coated plastics. 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 pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-press area compounding, and automatic rewinding, as well as mechanical transmission, pre-coating plastic film flattening, vertical and horizontal slitting, and computer control system And other auxiliary devices.
        1. The automatic conveying mechanism of the printed matter input part can ensure that the printed matter does not overlap during the transmission and enter the composite part at an equal distance. It is generally controlled by pneumatic or friction methods. The conveyance is accurate and high precision. It can also be used when the printed product with a small composite format is small Meet the above requirements.
        2. The composite part includes a composite roller group and a calender roller group. The composite roller group is composed of silicon rubber heating pressure roller 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 is: after the pre-coated plastic film and the printed matter are compounded by the composite roller group, the surface brightness is not high. After the secondary extrusion of the calender roller group, the surface brightness and adhesion strength are 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.
