Brief analysis of laminating machine manufacturers There are two major types of laminating equipment: instant coating laminating machine and pre-coating laminating machine. The instant coating laminator has a wide application range, stable and reliable processing performance, and is a widely used laminating device. Pre-coated laminating machine, no gluing and drying parts, small size, low cost, flexible and convenient operation, not only suitable for laminating processing of large batches of printed products, but also suitable for laminating processing of small batches and scattered printed products such as automated desktop office systems .
The laminating machine manufacturers briefly analyze the coating forms of the laminating machine: drum reversal type, concave type, direct glue without scraper, and direct glue with scraper.
1. Brief analysis of concave glue application by laminating machine manufacturers. It consists of a metal glue roller with a textured surface and a group of film partition rollers. The glue roller is directly immersed in the glue solution, and the glue solution is taken out from the glue storage tank with the rotation of the roller. The excess surface is scraped off by the scraper Glue. Under the action of the film pressing roller, the glue in the groove of the roller is driven by the film to be coated which is directionally moved and is evenly spread on the film surface. The amount of glue can be controlled by adjusting the grid pattern on the surface of the coating roller shaft, the characteristic value of the adhesive, and the pressure value of the laminating roller. The advantage of concave coating is that it can control the amount of coating more accurately and coat evenly; however, the anilox roller is difficult to process and easy to damage, and it needs to be cleaned frequently. In addition, the coating requires higher adhesives.
2. The manufacturer of the film laminating machine briefly analyzes the reversal coating of the roller. It is an indirect glue coating, which is the most widely used by various models. . The glue supply roller brings out glue from the glue storage tank, and the glue scraping roller and the glue plate can scrape the excess glue back to the glue storage tank. The film counter-pressure roller of the laminator presses the film to be applied to the surface of the glue roller after the glue is homogenized, and maintains a certain contact area, and the glue solution is continuously coated on the surface of the film under the action of pressure and adhesion. The amount of glue can be changed by adjusting the distance between the rubber roller and the rubber roller, and the rubber roller and the rubber sheet.
3. A brief analysis of the laminating machine manufacturers without squeegee roller extrusion coating. The glue roller is directly immersed in the glue liquid. During the coating, the glue roller brings out the glue liquid and passes through the glue roller. After the glue is evenly glued, the glue is applied by the pressing force between the film pressing roller and the glue roller.

The laminating machine manufacturer explained that for the laminating process, it mainly uses two types of materials: film and adhesive. The films used for coating mainly include bidirectional stretched acrylic film (BOPP) and polyvinyl chloride (PVC), among which BOPP film is the most widely used. Adhesives used in laminating can be divided into oily laminating adhesives and water-soluble laminating adhesives. For water-based glues, the most commonly used in production are EVA resin (ethylene vinyl acetate copolymer resin), acrylic resin, etc. In terms of its chemical structure, there are one-component and two-component, through the following aspects and Let's discuss together:
①Printing powder
Because the water-based glue can dissolve the powder sprayed on the surface of the printed product, when the snowflake point appears on the film-covered product, it is incomprehensible. In fact, the reason is very simple. The water-based glue itself is also limited by the solubility. When the amount of powder sprayed on the printed matter is greater than the dissolving power of the glue, the excess part cannot be dissolved or covered by the glue, and a large number of snowflake spots will appear. In this case, there are several solutions:
1. Coordinate the upper and lower processes to minimize the amount of powder sprayed during printing.
2. When laminating, increase the amount of glue properly and increase the ability of the glue to dissolve the powder. In actual production, the maximum amount of glue is to reach the maximum amount of glue when the product edge does not overflow.
3. Clean the suspended powder on the surface of the printed matter before laminating, you can wipe the surface manually, or install other powder removal devices on the machine.
②Clean
The laminating machine manufacturer explained that because the water-based laminating adhesive dries quickly, if it is still and does not flow, and it is exposed to the air for too long, it will dry and form a skin, which will be attached to the rubber coating roller or the pressure roller, resulting in partial coating. Or the glue layer is too thin, which also causes local pressure to increase, so keep the glue roller and pressure roller clean during the laminating process. In addition, there is too much dust in the surrounding environment or there is dry rubber and cut in the glue. The film fragments underneath will also affect the quality of the film, so it is necessary to pay attention to cleanliness and hygiene, and pay attention to the storage of glue. You can add a filter device for glue in the actual and production process.
③ Paper-plastic separation
The phenomenon of paper-plastic separation is easy to appear in products with a large printing area and large solid areas. Because the surface ink layer is thick, the glue is difficult to wet, diffuse, and penetrate, so the adhesion is not strong. The solutions are:
1. Check the production date and shelf life of the glue to see if the glue has deteriorated.
Second, whether the film is within the shelf life, what is the surface corona value.
3. Refer to the technical indexes of the glue, whether it is operated correctly according to the regulations in actual production
4. Replace other brands of glue with large viscosity.
5. Improve the environmental humidity when the film and product are dry.
④ deformation
There are several reasons for the deformation:
1. The amount of gluing is too large, the paper absorbs moisture and deforms, so under the prerequisite of ensuring product quality, the amount of gluing should be reduced as much as possible.
Second, the film is seriously stretched and deformed. At this time, the loose tension of the film should be adjusted appropriately. The smaller the tension, the better the film should be evenly attached to the paper.
3. The winding tension is too large. At this time, according to the situation, when ensuring that the product is transported and wound onto the roller, the smaller the tension, the better.
4. The temperature and humidity of the external environment where the product is located vary greatly.
In general, with the rapid development of the printing and packaging industry, the continuous innovation of processes, the continuous emergence and replacement of new materials, we will also face new problems and new challenges. Laminating machine manufacturers will also follow the pace of the times and seek higher development.

Selection requirements for laminating materials of automatic laminating machine:
The plastic films commonly used in the current laminating process of automatic laminating machines are: polyvinyl chloride (PVC), polypropylene (BOPP) and polyester (PET) films. Among them, BOPP film (15～20pm) is flexible, non-toxic, high in transparency, and cheap in price. It is an ideal composite material in the laminating process of the automatic laminator.
In order to meet the requirements for the use of laminating printed matter of the automatic laminating machine, the plastic film should meet the following requirements:
(1) Thickness directly affects the light transmittance, refractive index, film fastness and mechanical strength of the film, and the appropriate film should be selected according to the performance of the film itself and the purpose of use;
(2) After being treated by corona or other methods, it has better wetting performance and adhesion performance;
(3) The higher the transparency of the film, the better, so as to ensure the best clarity of the printed matter covered;
(4) The film should have good light resistance, not easy to change color under long-term light exposure, and have certain mechanical strength and flexibility characteristics;
(5) The appearance of the film surface should be smooth, free of irregularities and wrinkles, no defects such as bubbles, shrinkage holes, pinholes and pits, and no contamination of the film surface with dust, impurities and grease.

In the process of using the automatic laminating machine, there will be some small problems. These problems may be caused by our inadvertent use during the ordinary use process. There are also some reasons because of the length of time that a full-automatic laminating machine is used. As a result, the automatic laminating machine manufacturers conducted an investigation on this, and found that the common problems when using the automatic laminating machine are nothing more than three types: electrical circuit, rubber circuit, and gas circuit.
1. Circuit problem, if it is rubber birch or automatic laminating machine, the hose is not heated. Let's first check whether the fuse is burned out, whether there is any problem with the fusion, and check the temperature controller and the solid state relay or IC. If there is no problem with the above, then there is a problem with the circuit. You should check the circuit.
2. The problem of the plastic line. When the temperature of the hose glue gun is normal, it is the glue road problem that the glue does not come out. First check which part does not come out. The glue is the problem of the glue gun. The glue gun should be cleaned. If there is no glue out of the hose, there may be a problem with the host. There are three reasons why the host does not give out glue. One is that the inverter is broken (sent for inspection or replacement); the other is that the motor has problems (same as handling the inverter); There is a problem with the pump (check whether the seal or the pump is broken).
3. The problem of the air circuit, in the process of using the automatic laminating machine, the solenoid valve is generally used for control. This causes a problem in the gas circuit. If there is a problem in the gas circuit, first check whether the gas is reversed or whether the solenoid valve is It is broken, or the wrong type of solenoid valve is used.
