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.

        The hot laminating machine instant coating laminating machine includes three parts: gluing, drying and hot pressing. It is a pre-coating laminating machine widely used in China at present. There is no gluing and drying parts. It has small size, low cost and flexible operation. Convenient, not only suitable for laminating processing of large quantities of printed products, but also suitable for laminating processing of small batches and scattered printed products such as automated desktop office systems, which has a promising future.
        The laminating process is a surface processing process after printing. It is also known as post-press lamination, post-press laminating or post-press laminating. It refers to the use of a laminating machine to cover a layer of 0.012 ～ 0.020mm on the surface of the printed product. The thick transparent plastic film forms a paper-plastic integration product processing technology. The laminating machine is the equipment used to complete the laminating process. Generally speaking, it can be divided into two types: instant coating film and pre-coating film according to the process used, and two kinds of bright film and matte film according to the different film materials.
        This type of thermal laminating machine is widely used in photo agencies, printing plants, advertising, design and adhesives. It has less investment and obvious effects. The consumables used are non-polluting. They are green and environmentally friendly products and have great market potential.
        Operation process steps of hot laminating machine:
        The first step is to use a bracket to stabilize the thermal laminator and fix it firmly on the workbench. To make a special platform for laminating, this step is actually to fix the machine and arrange the platform for laminating. This is the beginning and the key step. Whether the product has a good laminating effect is the key.
        The second step is to fix the material needed for the film on the iron roller, and the film coating is facing upward, adjust the pressure of the rubber roller, slowly adjust it, and remove the material that needs to be coated from the middle of the rubber roller and the machine. Just wear out more than 10 centimeters.
        The third step is to tighten the product and adjust the position, which is a good display of the effect of the film when the product is used, and has become a key point of elaborate production. In addition, in the early operation, we must pay attention to the effect of fixing the product to avoid skew.
        The fourth step, if you need to mount the film, you need to pass the cold laminating film out of the two rubber rollers of the laminating machine, 10 cm, and place it on top of the consumables. position. The pressure on both ends must be the same.
        The fifth step, when there is a slanting phenomenon in the process of use, it means that you have not placed it properly, and it should be carried out after being placed. You can go for a short time, cut it off slowly, re-center it, and start the machine to work. (Remind everyone, you must be even and stable when you are correcting, take your time)
        The sixth step, if there are wrinkles, don't stop the machine immediately, let him continue to run for a while, then stop the machine, and slowly take out or cut the film, if you are using a cold laminator, it may be There will be excessive pressure, because the machine itself has not completely stopped, and the problem can be solved after the machine stops.
       The above is a detailed explanation of the steps of the operation process of the hot laminating machine. If you have any questions, please call our factory for consultation. There will be professional technical staff to teach you how to do it.

        Quality standard after laminating machine printing:
        1. The color of the printed pattern remains unchanged, and it will not change color under the sun, baking and ultraviolet radiation.
        2. The film is firmly bonded, the film layer cannot be easily separated, the surface is clean and smooth, not blurry, good finish, no wrinkles and powder foil marks. Any wrinkles and creases are considered unqualified products.
        3. The film-covered product must not be curled, the size after division is accurate, the edges are flat and smooth, and no film or film loss can occur. The break is no more than 4㎜.
        4. The degree of drying after coating is appropriate without sticking to the surface. On thick solid and dark areas of the ink, there should be no sand bumps, stripes, or worm-like film bumps.
        5. After the film is placed for 10-20 hours, there is no change in product quality.
        Extending the life of the laminating machine is mainly for the maintenance of the motor when using it. The main points to pay attention to are the following:
        1. Clean up debris, dirt on the motor, nearby debris, and stay away from flammable and explosive materials.
        2. Before starting, you should check whether the machine rotates smoothly, whether it is blocked, and whether the belt connection is normal; if there is any abnormality, you should never continue to start the glue machine.
        3. The voltage at start-up should meet the rated voltage; the general voltage value is about 5 to 10 percent of the rated voltage value.
        4. After the motor fails, you must cut off the power supply and can not continue to use; you should find a professional to repair.
        As long as the life of the laminator is maintained, correct operation, maintenance, and maintenance; other parts also need to be well maintained; careful maintenance and maintenance are a good way to extend the life of the machine.
