In the packaging and printing industry, the exquisite appearance and protective performance of products have always been the focus of attention of enterprises. With the intensification of market competition and the increasingly strict requirements for the quality of packaging and printed materials, the automatic embossing and laminating machine was born, which is gradually becoming an important driving force for the transformation and upgrading of the industry. It can not only give the print a unique texture, but also improve its durability through laminating technology, which is deeply favored by major printing enterprises. The automatic embossing laminating machine is mainly composed of core parts such as rolling, glue coating system, embossing unit, laminating mechanism, drying equipment and winding device. Each part works together to realize the efficient transformation from raw materials to finished products.
As the starting link, the roll-up device bears the heavy responsibility of stable output of printed substrates and film materials. The substrates of printed materials are usually paper, card paper, etc., and BOPP (two-way stretch polypropylene film), PET (polyethylene terephthalate film), etc. are mostly used for the film, because of their good transparency, flexibility and moisture resistance. The rewinding device is equipped with a high-precision tension control system, which monitors the material tension in real time through the sensor, automatically adjusts the unwinding speed, ensures that the tension is constant during material transportation, avoids material wrinkles, tensile deformation and other conditions, and lays the foundation for the smooth development of subsequent processes.
The glue coating system is the key link in determining the quality of the coating. Using advanced mesh roller glue coating technology, the glue is accurately and quantitatively transferred to the surface of the film through the tiny mesh holes evenly distributed on the surface of the mesh roller. The number of net lines and the volume of the mesh roller are carefully designed, which can flexibly adjust the amount of glue coating according to the requirements of different film materials and coating processes to ensure that the glue is uniform and appropriate. The choice of glue is also quite particular, taking into account the good adhesion of the film and the printed substrate, as well as the drying speed, environmental protection performance and other factors. At present, water-based glue is more and more widely used in the industry due to its green and environmental protection characteristics.
The embossing unit is the feature of the automatic embossing laminating machine, which can give the printed matter rich and diverse texture effects. When the printed material and the glued film enter the embossing area synchronously, the embossing roller will clearly emboss the roller surface pattern on the composite layer of the film and the printed matter under the action of pressure, instantly improving the three-dimensionality and texture of the product. The unique embossing effect can significantly enhance the visual impact and tactile attractiveness of the product, making the packaging stand out on the shelf, which is of great significance to high-end product packaging, art prints and other fields. Parameters such as embossing pressure, speed and temperature can be precisely regulated according to actual needs to ensure that the embossing effect is clear and consistent, and will not cause damage to the film and print.
The coating mechanism is responsible for closely fitting the coated film with the print to form a solid composite layer. During the fitting process, uniform pressure is applied through a set of rubber pressure rollers to promote full contact between the film and the printed matter, and the glue is quickly cured to achieve a firm bonding of the two.
After the drying equipment follows the coating mechanism, the compounded products are quickly dried to accelerate the glue curing and improve the coating strength. There are various drying methods, including hot air drying, infrared drying, etc. Hot air drying heats the product evenly through circulating hot air, so that the glue quickly evaporates the solvent and realizes curing; infrared drying uses the thermal effect of infrared rays to directly act on the glue layer, with high heating efficiency and fast speed.
The automatic embossing laminating machine shows excellent advantages in actual production. Rich embossing effect and high-quality film coating. In terms of environmental protection, the automatic embossing film coating machine adopts water-based glue, energy-saving drying technology, etc., which effectively reduces the emission of volatile organic compounds (VOCs), which is in line with the current green development concept.If you want more details, please contact us and we will answer for you within 24 hours.
