What is a fully automatic laminating machine?
The automatic laminating machine is for the surface lamination of printed matter, books, posters, color box packaging, handbags, etc. In response to the continuous improvement of global environmental awareness, oil-based coatings will gradually be replaced by water-based coatings.
The four most commonly used lamination processes in China's laminating machines today. Of course, among the laminating devices in China, the most common is water-based dry lamination. The water-based dry covering uses coating glue for drying, heat covering, slitting, and receiving the paper. This lamination process should be the most widespread in China; the second is pre-coated, which is a kind of glue itself on the film, and then the paper is heated with a roller after entering, and then the film is The glue on top dissolves and sticks out. The third is water-based wet coating. This process is a process in which the adhesive is not dried, but the paper comes directly over (but there is no pressure for lamination) and then rolls up. After letting it cure naturally, the glue is absorbed by the paper and then pulled off. The fourth is the hot melt adhesive lamination process. Of the first three technologies, among all slitting, punching, flying knife, chain knife, hot knife, and other technologies, the hot knife is the most advanced technology in the world. It has the fastest speed and the most stable slitting. After slitting, the coated product has no tail film or film debris. It is an ideal slitting method. Tian uses this hot knife technology on water-based dry lamination and a hot knife to cut, which needs to be very accurate, and the error of 1 or 2 mm cannot appear. Therefore, the manufacturing of the machine requires very high precision. In market promotion and operation, customers are interested in the machine, especially the middle and high-end customers. Because of the future development trend of film, PET film is still needed from the perspective of environmental protection and the quality of the film. The OPP film on the market now accounts for the majority. The OPP film needs to be punched with a disc knife and can be broken as soon as it is pulled. The PET film is constantly removed and must be cut completely. Therefore, customers are very concerned about hot knife slitting technology.
The head of the automatic laminating machine adopts the automated feeding system of the feeding head, the pressing steel rod adopts the hot oil circulation heating system, the composite pressure adopts the air pressure device, and the electrical system adopts PLC programming control. The slitting system is equipped with a knife and rotation Flying knife slitting device, the back of the laminating machine is equipped with an automatic paper delivery system, the whole machine occupies a small area, has a high degree of automation, is easy to operate, and has high stability.

What is the machine parameter of the machine?
It's a digital, fully automatic machine(with oil heating, pulling off, and double sides laminating). We have two types of this model. They are SMFM390E and SMFM520E. The different numbers represent different widths of their size. As you know, the width depends on the max paper size. Thus, the max paper size is also different from the other one.
On the other hand, the other parameters are all the same as each other. Their operating speed is 0-10m/min, and their laminating temperature is 80~125℃. Furthermore, the total power is 3kw. Besides, the pressure is 0.1~0.5MPa. Moreover, the maximum height of the paper is 5cm. At last, the full height of the article is 8cm. The max paper size is respectively 350mm and 480mm. And the dimensions(L×W×H) are 1.5×0.63×1.2m and 1.5×0.8×1.2m.
What are the Use process requirements of the laminating machine?
1. Drying temperature - controlled between 50 and 70℃, which can fully volatilize the solvent and prevent the film from overheating and deforming;
2. Composite temperature - the temperature of the imprinting cylinder is controlled at 70-90℃, which can dissolve not only the adhesive but also the film will not be overheated and deformed;
3. Compound pressure - to ensure that the axial force of the impression cylinder is consistent, and the pressure should be kept within 150-250 kg/cm²;
4. Adhesive coating - the coating should be thin, controlled at 3-8 g/cm², and the thickness is 5-8 μm to avoid an overly thick layer;
5. Machine speed - single sheet of paper should be controlled at 35-45 sheets/min, roll paper should be held at 3-10 m/min, and it is also related to other parameters;
6. Film tension - the tension is adjusted to the lowest level to achieve correct coating and compounding, and it is necessary to avoid excessive pressure;
7. Cylinder accuracy - the surface of the impression cylinder is required to be smooth and clean, without scratches and pits. To ensure the ovality, concentricity, and other mechanical accuracy indicators;
8. Environmental factors - Air purification devices are required to keep the environment clean. Control the temperature and humidity of the workshop to prevent the deformation of paper or film;
9. Ink thickness - dark ink and light printing are required to avoid the surface tension drop due to excessive thickness of the ink layer, making the film not strong;
10. Ink drying - ink drying should be thorough to avoid foaming;
11. Ink additives - control the desiccant amount to prevent the ink layer's crystallization. The surface of the ink crystallized by the automatic laminating machine will appear to be unstable.
What are the performance characteristics of the laminating machine?

5. Adopt the electric heating oil heat conduction method to save power consumption costs and make the temperature more stable;
6. Label anti-roll device.
What are the factors that affect the quality of the laminating?
1. Prints with poor flatness are prone to wrinkles when laminating. Due to the unevenness of the paper, the adhesive cannot be evenly coated on the article, resulting in delamination and foaming.
2. After the product is printed, it should be stored for some time to facilitate the volatilization of moisture in the paper.
3. If the surface roughness of the printed matter is too high, it will affect the castability (leveling and spreading) of the adhesive, resulting in uneven gluing, and the surface of the coated product will produce bright spots or "fog" with different gloss.
4. Chemicals are inevitably used in the printing process, which can easily change the surface structure of the paper so that the adhesive cannot be in good contact with the form, causing the product to foam after being placed for a long time.
5. When the automatic laminating machine is in the peritoneum, the adhesive layer on the surface of the printed matter is dried until the initial dryness, and the thickness is about 0.002mm to 0.003mm. Therefore, if the powder spray on the printing material is too thick, the film will not be compacted, resulting in fine particles on the product—snowflake-like spots.
6. If the ink layer on the surface of the printed matter is too thick or not dry, the adhesive applied by the automatic laminating machine during lamination cannot usually penetrate the pores between the ink layer and the paper for adhesion, which will cause false adhesion, resulting in The finished lamination foams in a short time.
What are the functions of the fully automatic laminating machine?
With the development of social modernization, people's awareness of environmental protection is constantly improving, and water-based coatings are gradually replacing oily layers. The automatic laminating machine is also mainly used for laminating on the surface of printed matter, such as books, posters, color box packaging, and handbags. Many people have many big misunderstandings about its functions. Let's take a look at the parts of the automatic laminating machine.
