The automatic laminating machine is to apply adhesive to the plastic film, combine it with the printed matter using paper as the substrate, and press the rubber cylinder and the heating cylinder to form a product combining paper and plastic. Due to the thin and transparent plastic film on the surface of the printed product, the surface is smoother and brighter. The automatic film laminating machine not only improves the gloss and fastness of the printed product, but also extends the life of the printed product The film also plays a protective role such as waterproof, anti-fouling, abrasion resistance, folding resistance, and chemical resistance.
        If a transparent bright film laminating film is used, the printed graphics and text of the laminating product are more vivid and full of three-dimensional sense, which is especially suitable for the packaging of green food and other commodities, which can arouse people's appetite and consumption desire. If a matte film lamination is used, the lamination product will give consumers a noble and elegant feeling. Therefore, the packaging printed matter after laminating can significantly improve the grade and added value of the product packaging.

        A film laminating machine used in the manufacturing process of metal membrane switches. This film laminating machine includes a frame and a driving device, a control device and a film material bracket provided on the frame. The frame includes a frame body and a horizontal operation panel provided on the top of the frame body. Through hole; the material support includes two pillars provided on opposite sides of the through hole and a cross bar provided on the two pillars; the driving device includes an upper roller provided above the operation panel, Three or three upper lower rollers below the operation panel, a conveyor belt sleeved on the lower roller, and a motor driving the lower roller, the upper roller and the lower roller are both arranged across the through hole, and the upper roller is directly below A lower roller is provided; the control device is a control box for controlling the motor. The invention provides a production device with simple operation, improves the production efficiency of the membrane switch coating process, and greatly reduces the incidence of defective products during the coating process.
        Laminating machine, in order to overcome the lack of rapid roll changing mechanism of the original laminating machine in the color coating production line, the working efficiency is poor, the accuracy is poor, the response is slow, and the manual alignment is labor-intensive. This type of laminating machine is composed of an uncoiler, a looper, and a laminator.The decoiler is fixed on the base of the looper, and the laminator is installed on the production line. Continuous production, automatic centering, automatic flattening, and temperature adjustment function greatly improve work efficiency and save production costs.

        The pre-coating film laminating machine has been used for a long time, and it must be maintained. If the laminating machine is adjusted or improperly maintained, it is also easy to cause errors in the mounting of facial paper and corrugated cardboard.
        The problems that often occur in the pre-coating film laminating machine are as follows:
        (1) There is a loose phenomenon in the paper feeding chain mechanism, which makes the working coordination of the upper and lower chains inconsistent or unstable; the front regulations on the upper and lower chains are loose, which causes impact on the edge of the paper when feeding;
        Treatment method: For loose front rules, according to the loose parts, the corresponding tight treatment should be taken in time;
        (2) The contact position of the paper pressing steel strip to the facing paper is uncomfortable or the gap is too large, and it does not play a role in slowing down the inertial impact force of the cardboard at high speed;
        Treatment method: Adjust the position of the paper pressing steel strip to maintain a certain friction with the cardboard to prevent the paper from being too violent and advanced; the glue or dirt on the upper and lower rollers should be cleaned regularly.
        (3) The upper and lower rolling rollers accumulate a certain amount of glue because they are not cleaned frequently, which prevents the synchronous rolling transportation of facial paper and corrugated cardboard
        Treatment method: The chain of the pre-coating film laminating machine is the main component that drives the machine. It must be kept clean, so it should be cleaned, cleaned, and maintained with good lubrication in a timely manner.

        In the processing file of the laminating machine, the requirements for each part of the machine are very high, such as the accuracy of the surface of the rubber roller. If the rubber roller has some marks, scratches, deformation, etc., the processed files will affect the processing effect. For example, after processing, it is blurry and unclear; such processed files also need to be reworked, which will be very troublesome. It can be seen from this that the precision of the machine is inseparable from the maintenance after using the laminator, and regular inspection and maintenance. So, what should be done for daily maintenance?
        Always check the oil pipes, valves and cylinder plugs of the hydraulic system for oil leakage. When oil leakage is found, replace the sealing ring in time and fill the hydraulic cylinder with an appropriate amount of hydraulic oil.
        The blade line of the scraper blade should be kept flat and flexible. When there are detours, teeth, curling, etc., it should be repaired and replaced in time. Use 0.15 ~ 0.20 mm manganese steel skin or the blade of the offset press, and replace it according to the original size Of it.
        Lubricating oil must be added to the transmission parts and sliding surfaces of the machine regularly to ensure that the machine is in a good lubrication state. In particular, due to the high pressure and high temperature encountered by the large bearing of the pressure roller, the lubricating oil is volatilized and lost. The dwarf high-temperature lubricating oil should be timely so that it can normally perform its duties under high temperature and high pressure.
        Check whether there is rubber or grease on the rubber roller, and wipe off the glue and dust on the roller in time. Keep the two rolled surfaces clean and dark. The surface of each roller must be kept seriously clean. Always clean the machine immediately after applying the machine. Wash with glue thinner (alcohol or xylene) and wipe each roller with a soft towel. It is strictly forbidden to scrape the surface of the roller with a sharp tool. Every time the machine is turned on, the dust on the surface of each roller should be wiped off. And check whether the surface of each roller of the machine is dark, the machine is malfunctioning or abnormal sound, should analyze and find the reason in time and remove it. After the standby device is normal, you can continue to use the machine.
        The above are the points that should be done when doing maintenance for the laminating machine; in addition, when you find that the machine has a problem, you should contact the relevant professionals for repair in time; early detection and early treatment can save you A lot of unnecessary trouble.

        The cold laminators and hot laminators currently on the market are prone to warp phenomenon for thin paper lamination (unless a professional and high-cost anti-roll single-sided hot film is used). Bubbles and wrinkles may appear after curling and unfolding. One-sided cold mounting will also curl the paper, especially paper under 100g is prone to curling. The following will tell you the causes and solutions of the wrinkling of cold laminating film.
        For small and medium-sized graphic fast printing and units, the more choice is the thermal laminator. The overall effect is still good, but if you use too thin paper such as 100g or less, it will curl, which requires technical guidance. The operation will be slightly slower. , But it does not roll at all, or the effect of choosing a fully automatic laminating machine is different. Most customers can understand this, but if the paper is wrinkled, the general maintenance solution is as follows:
        1. The pressure of the roller is uneven, causing the paper to wrinkle during the lamination process. In this case, the pressure of the roller should be corrected before starting operation.
        2. There is dirt on the rubber roller, which causes the paper to wrinkle during laminating. The rubber roller should be cleaned in time. The rubber roller must be kept clean frequently.
