Laminating equipment is generally divided into two categories, namely pre-coating laminating machine and coating laminating machine; pre-coating laminating machine due to some objective constraints.
        As a result, it is rarely used in China and has not been popularized, but the development prospect is very good; that is, the coating laminator is widely used and has stable performance, and is currently widely used; large and small batches of lamination processing. At present, there are advanced automatic machines in China, which have promoted the price difference of laminating machines.
        That is, the film coating equipment is a special equipment that applies the adhesive to the reel plastic film after being dried, and then pressurized composite parts are combined with the printed matter. It is divided into two types: automatic laminating machine and semi-automatic laminating machine. The working principle of each model is the same. The structure and the laminating film are unique. They are roughly divided into unwinding, gluing, drying, laminating, It consists of five parts for rewinding and auxiliary devices such as automatic tension control, mechanical transmission, and automatic deviation adjustment for unwinding.
        Machines such as pre-coated film equipment are special equipment for compounding printed materials with pre-coated plastics. Its biggest feature is that there is no sizing and drying part, and it has fewer steps than the instant film coating equipment; so this type of machine has a compact structure, low cost, easy operation, and high stability. The pre-coating laminating machine consists of four main parts: pre-coating plastic film unwinding, automatic input of printed matter, hot-pressing zone compounding, and automatic rewinding. And other auxiliary devices.

(If there is no optional automatic take-up machine, add a counter before receiving the cardboard to measure the alarm.)

        The automatic laminating machine is best to regularly check whether there is glue or grease on the rubber roller, and wipe the rubber trace and dust on the roller in time. Ensure that the appearance of the two rolls is washed black. The surface of each roller must be cleaned. Not only is it necessary to clean the machine immediately after using the machine each time. Wash with glue thinner and wipe the rollers with a soft towel. It is strictly forbidden to scrape the surface of the drum with a sharp tool. Every time the machine is turned on, the surface dust of each roller should be wiped off. Computer bronzing machine and check whether the appearance of each roller of the machine is black, when the machine shows defects or abnormal dynamics, it is necessary to analyze and find the reason and eradicate it in time, and wait until the machine is normal before allowing it to continue to operate.
        The blade line of the scraper blade of the automatic laminating machine should be flat and flexible. When the appearance of detours, teeth, curling, etc. should be trimmed and replaced in time, use 0.15 ~ 0.20 mm manganese steel skin or the blade of the offset press, press Exchange the original standard. Lubricant should be added to the transmission parts and sliding surfaces of the machine on time to ensure that the machine is in excellent lubrication conditions. Especially the large bearings of the pressure rollers are subject to high pressure and high temperature, and the lubricant is evaporated and thrown away at will. High temperature lubricating oil, so that it can operate normally under high temperature and high pressure. The floor formwork support of the automatic laminating machine uses the steel pipe bracket composed of the connection piece and the steel pipe, and gradually opens up perfectly as a fastener type steel pipe bracket.
        (1) The printing ink layer is not completely dry: hot pressing first and then gluing, can also delay the film date, making it completely dry.
        (2) The printing ink layer is too thick: the amount of adhesive coating can be added properly to increase the pressure and compound temperature.
        (3) The surface temperature of the composite roller is too high: adopt air cooling, closed electric heating wire and other heat dissipation methods to quickly reduce the temperature of the composite roller
        (4) The dry temperature of the film is too high: if the dry temperature is too high, it will cause the skin of the adhesive to cause blistering problems. At this time, the dry temperature should be properly reduced.
        (5) The reason of the film: blistering problems caused by wrinkled or loose appearance of the film, uneven or curled film, can be dealt with by adjusting the tension size or replacing the qualified film.
        (6) The reason for the concentration of adhesive: high adhesive concentration, high viscosity, uneven coating, and low dosage are also one of the reasons. At this time, thinner should be used to reduce the concentration of adhesive, or appropriately increase the amount of coating And uniformity.

        When using a fully automatic laminating machine, pay attention to compounding the prints together. Another biggest feature is that there is no glue coating. When drying, the structure of the laminating machine will be compact and the volume will become smaller. At this time, we must pay attention to the operation of the hot stamping and creasing machine. If the operation is good, the product quality will be good, and the stability of the computer hot stamping machine will be high. During printing, the automatic conveying mechanism can ensure that there is no overlap in the transmission of printed products , And can ensure automatic access to the composite part, most of the machinery uses pneumatic or friction to achieve this, automatic laminating machine is not used, can meet these requirements, can also ensure the accuracy of conveying And accuracy!
        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 treated. If the number of prints is large, the powder can be hung to dry to remove the powder.
        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.

        After the laminator is adjusted, the pre-processed printed matter is sent to the paper feeding mechanism for lamination, and samples are taken for inspection. Use a small amount of printed matter to inspect before laminating, so as not to cause a lot of waste. After passing the inspection, mass production can be carried out. The method of using the film inspection is as follows:
        1. Tear off the corner of the proof sheet completed by the lamination in the width direction, press and hold the paper, and tear it all in the width direction. After tearing off all the tears, if the graphic imprint on the surface of the printed matter follows the glue layer and the fiber of the paper Transferred to the film, it means that the printed matter and the film adhere well, and it is a qualified product.
        2. Put the film-coated sample into the drying tunnel and bake at 60-65 degrees Celsius for about 30 minutes. If there is no blistering, no delamination and no wrinkles will occur, and it is a qualified product. After baking, the tear film should not be separated from the paper intact.
        3. Immerse the sample in cold water for 1 hour and take it out. If the plastic film is not separated from the printed product, it is a qualified product.
        4. Put the sample on the creasing machine and apply pressure. If the pressed uneven part does not delaminate, it is a qualified product.
