Pre-coated film laminating machine is a process method to protect and decorate the surface of printed matter. Laminating film occupies a large share in post-press processing. Just walk into a bookstore and you will find that most books use this method . This is because the surface of the laminated printed matter will be smoother, brighter, stain-resistant, water-resistant, and abrasion resistant. The cover of the book is more colorful and not easily damaged. The printed matter has abrasion resistance, folding resistance, tensile resistance and The moisture resistance has been greatly strengthened.
It protects the appearance effect of all kinds of printed matter and improves the service life. The most noteworthy thing about the pre-coating laminating machine is that the laminating film can make up for the quality defects of the printed products to a large extent. Many apparent defects appearing in the printing process, after laminating (especially after the matte film ), can be covered. People’s awareness of environmental protection has gradually increased, and relevant laws and regulations have been continuously improved. The two major problems of pollution during the film processing and the difficulty of recycling when the film is discarded are facing people.

The self-adhesive laminating machine market in my country is still a "prosperous" scene. To talk about book decoration, we must talk about laminating technology. This status quo has its inevitability:
(1) Laminating equipment and technology have been quite mature after years of development and improvement.
(2) Laminated products have many advantages. See the role of film for details.
(3) Laminating machines are relatively cheap, and printing plants are willing to introduce them. The cost of the laminating process is not high, and publishers are willing to improve the performance and aesthetics of books and periodicals through laminating. Both printing houses and publishing houses can obtain certain benefits from laminating.
With the development of science and technology and the strengthening of human awareness of environmental protection, "green environmental protection" will become an inevitable trend in the development of self-adhesive laminating machines. To be sure, in the future development process

Self-adhesive trademark laminating machine-on laminating machine or gravure printing machine, mainly used for laminating film materials. The dry laminating film of the roll material is suitable for mass label products, with good film quality and low cost. After the roll label is coated, the secondary processing such as die-cutting and waste discharge is usually carried out on the processing machine, such as some battery labels and wine labels.
UV coating process-the latest foreign technology, mainly used in the unit type rotary label machine with UV drying device. The process principle is: the surface of the film material is first printed with a UV adhesive by the ordinary printing unit, and the adhesive is cured by a UV drying device to become a pressure-sensitive adhesive. Then the ordinary BOPP film (the general composite surface has been corona treated) is compounded with the reel material at the laminating station to complete the laminating process. The cost of UV coating is low, the tension of the composite film is small, no special film is needed, and it is suitable for high-speed production. UV coating is a promising process and has been applied in developed countries in Europe and America.

The main performance of the trademark laminating machine is that after the composite finished product is slit, it appears curling in the direction of the film and cannot maintain a flat state. In severe cases, it will automatically curl into a cylindrical shape. main reason:
①The coated paper is too thin;
②The paper has high moisture content and high humidity;
③The temperature is low;
④The paper is loose and flatness is poor;
⑤When laminating, the pressure is high, the temperature is high, and the time is long.

In the fault diagnosis of laminating machine, the method is not right and the influence of other factors, misdiagnosis or diagnosis can not reach a conclusion, it is the direction and goal of the field personnel to improve the diagnosis rate. On the other hand, fast is only a relative concept, which refers to the use of scientific and reasonable diagnosis methods to diagnose and eliminate laminating machine faults at a faster speed.
On-site fault diagnosis of laminating machine is often carried out under very incomplete conditions and very urgent situations. It is necessary to pay attention to strategies and skills, and its significance lies in using the system and information as a guide to fully understand the specific environment of the site , Select the correct ideas, strategies and methods for failure analysis, strictly organize the failure analysis process, avoid all kinds of confusion and mistakes, make up for insufficient conditions through appropriate methods, overcome various difficulties, reduce blindness, increase hit rate, and be fast and accurate Find out where the fault is and eliminate it, thereby achieving satisfactory work results.
