The amount of film used in the vacuum laminating machine is mainly related to the operation level. It is 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.
        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.

        In the plane coordinate system (the vertical coordinate is the Y axis, and the horizontal coordinate is the axis), any point can be represented by its coordinate, otherwise, the coordinate of any point can also be expressed in the plane coordinate system .
        The pull gauge is to solve the size of the Y axis direction
        The front rule is to solve the size of the X axis direction
        1. Common pull gauge
        1. Two tangential rollers (usually up and down positions) are positioned by turning to pull the paper to a fixed position. Among them, the lower roller makes 360-degree rotation, and the upper roller is passive follow-up. Under normal circumstances, the lower roller must be quenched, and the upper roller uses a rolling bearing with a dust cover, because the paper is more or less dust and paper wool, if these dust or paper wool enter the bearing, it will inevitably affect the flexibility of the bearing , It will affect the normal work of the pull gauge.
        2. One roller (bearing) and one pull bar.
        The scroll wheel moves up and down, controlled by a cam, which can adjust the up and down time. The rack is also controlled by a cam, which can adjust the back and forth time. (The rack must be quenched)
        3. One roller (bearing) and one sector plate.
        The paper roller is moved up and down, and the fan-shaped plate swings back and forth. The drawing rule of our current local machine is in the form of two rollers, and the drawing rule of the laminating machine belongs to the third form.
        Second, the characteristics of the two forms of regulation
        1. Two rollers: the lower roller makes a rotating motion, and when the upper roller is pressed down, it starts to pull the paper, otherwise, when the upper roller is lifted, the paper passes. This form is relatively simple, only one cam control is required in the structure, and the adjustment is relatively simple.
        2. The drawing gauge used by the laminating machine is a little more complicated. The upper paper-drawing roller (bearing) is controlled by a cam, and the bottom is the knurling roller, which is controlled by the other end-face cam. It is worth noting that the up and down time of the laminating machine cannot be adjusted and can only be coordinated by the lower roller and cam. In addition, the rollers below must have a high hardness, and they must be concentric, and there should be no jumping phenomenon. In addition, the pulling force of the paper is always greater than the 'supporting force' of the paper. So how to adjust the size of the pulling force to make it just right? First, rely on experience, explore carefully, and keep summing up. Second, it is guaranteed by design. Because the laminating machine does not have high requirements for drawing gauges, and it is mainly based on thick paper. Our debuggers and installers must carefully study the working principle and structure of the pull gauge to be able to cope with the various problems that actually arise.
        3. The Front Regulation Department
        1. The function of the front gauge cover is to ensure the accuracy of the X axis direction.
        For the laminating machine, adjusting the front rules is an important part to ensure the correct buckle. The laminating machine has 6 front rules. These 6 front rules should be adjusted to the same plane, and the height is basically the same (relative to the panel). The rise and fall of the pre-regulation should be active, but no looseness is allowed. The four sides of the front gauge should be smooth and wear-resistant, and the oil passage should be smooth.
        2. The main function of the front gauge wheel is to send out the paper that has been positioned. The two front gauge wheels must be able to turn flexibly, but they cannot be shaken from side to side. The two left and right front gauge wheels should be adjusted to the "light and heavy" consistency, and fine-tuning should be repeated during the adjustment to make it consistent, so as to ensure that the "buckle" is basically consistent.
        4. The relationship between the pull rule, the front rule and the paper feed wheel
        After we have basically understood the role of the pull rule, the front rule and the paper feed wheel, let's discuss the relationship between the three. (In this respect, the principle of the laminating machine and the local machine are similar, the same is the same)
        First of all, we need to adjust the pull gauge sleeve. When the lower knurling wheel just turned towards the "knock body", the upper pressing wheel (bearing) just pressed down on the lower knurling wheel, and a certain pressure was generated between the two, which also led The upper pressing wheel rotates (counter-rotating), at this time the paper should be between the upper and lower pressing wheels, and be pulled towards the "backer body". This is the paper pulling action.
         I think we must first find a basic point, that is, the end of the pull gauge action, the pull gauge paper pulling cam (upper pressure wheel) has just been raised, and the distance between the upper and lower wheels is a piece of paper. Use this as a reference to adjust the front gauge and feed roller. When the top of the front gauge is lowered to a position above the panel by one sheet of paper, the gap between the paper feed roller and the paper feed roller below should also be the thickness of a sheet of paper. At the same time, observe whether there is a phenomenon of "bowing up" when the paper is fed in the front regulation during paper feeding, and whether the paper feed is smooth, and then make micro adjustments.
        5. How to ensure that each piece of paper can be pulled to the designated position:
        As mentioned earlier, the pulling force of the pull gauge should be greater than the supporting force of the paper, and the pressure of its compression spring must be adjusted patiently. When the paper is pulled to the designated position, that is, against the "mountain", the paper roller should stop rotating, commonly known as "slip", and the pull gauge has a knurled screw for adjusting the compression spring. Turn the screw to adjust the pressure of the compression spring, so that the contact between the upper and lower rollers generates pressure (overpressure), which is the pulling force of the paper. (The upper pressure wheel should be able to rotate very flexibly without any damping phenomenon.)
        In physics, the magnitude of the frictional force (tensile force of the pull gauge) is equal to the positive pressure × friction coefficient. The outer knurling of the lower roller is to increase the friction coefficient. When the pull gauge is pulling the paper, if you feel the phenomenon of ‘pulling over the head’, you can adjust the knurled screw on the back to reduce the positive pressure. (The front knurled screw is not used to adjust the pulling force of the paper pulling cam.) When we observe the pull of the pull gauge, the gap between the pressure plate and the lower plate should be 3 times that of the paper to be coated. If there is no paperboard on it, it will be too far when pulling the paper. When changing from thin paper to thick paper, adjust the gap between the two boards: turn the knurled screw on the front to adjust the upper board to be raised or lowered. At this time, as the upper pressure wheel is raised (increased clearance) with the upper pressure plate, the gap between the upper pressure wheel and the lower roller is also increased, and the pressure between them is also reduced. It is necessary to adjust the eccentric shaft at the upper pressure wheel to ensure sufficient positive pressure. At the same time, it is necessary to adjust the length of the knurled screw behind the compression spring.

        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.
