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.
Trademark laminating machine is a process for protecting and decorating the surface of printed matter. Trademark laminating machine 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 to protect the appearance of all kinds of printed matter and increase the service life

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.

1. The product to be constructed on the laminating machine must be straight. Deal with uneven paper with "ruffles" and "tight edges". "Ruffle edge" paper can be baked, and "tight edge" paper can be hung.
2. Be sure to wait for the blot to dry before covering it, otherwise it will cause blistering or hairiness.
3. Spray powder as little as possible during printing, otherwise it will cause emptiness and blistering at the pile of powder. The powder spraying should be removed before laminating, the ones with more prints can be hung to remove the powder, and those with less prints can be wiped manually.
4. Pay attention to the direction of paper strands when laminating machine, especially thick paper, to reduce the curling phenomenon of paper due to rolling and stretching.

1. Professional multi-function laminating machine, which can do various work such as thermoplastic, cold laminating, low temperature cold laminating, thermal laminating, etc., suitable for graphic mounting and binding cover mounting;
2. The pressure and height of the rubber roller can be adjusted integrally on one side; the internal heating type double roller heating, intelligent constant temperature;
3. Light touch operation buttons, free temperature setting, 9 speed adjustment, LED digital display;
4. The upper and lower roll film supports can be heightened, and large roll thermal film can be installed to avoid the inconvenience caused by frequent replacement of roll film. The tension of the upper and lower roll film and the left and right sides of the roll film can be adjusted separately to ensure that each Laminating effect of various materials;
