Treating the surface of plastic bottles with flames can change the molecular structure of the plastic surface, changing it from hydrophobic to hydrophilic, enhancing the adhesion on the surface of the plastic bottle, allowing the subsequent screen printing ink to better adhere, and avoiding the appearance of ink Quality problems such as peeling off are particularly effective for some plastic materials with smooth surfaces and difficult for ink to adhere.
automatic transfer
An automated transmission system is adopted, such as through the cooperation of conveyor belts, robotic arms and other components, to accurately and stably transport plastic bottles to each printing station in sequence, ensuring that the entire printing process is coherent and orderly, which not only improves production efficiency, but also reduces labor Bottle damage and position deviation that may be caused by transportation.
Multicolor silk screen
It can realize screen printing of multiple colors. It is equipped with multiple printing units inside. Each unit is responsible for printing ink of one color. It also has a precise color registration and positioning system, which can accurately print patterns or text of different colors on plastic in sequence. On the bottle, it meets the needs of complex and colorful pattern design. For example, some plastic bottle packaging with exquisite brand logos and creative patterns often require multi-color silk screen printing.
UV curing
After the screen printing is completed, the UV curing device is used to emit ultraviolet rays to quickly solidify the ink. This curing method is fast, and it usually only takes a few seconds for the ink to dry and solidify, which greatly improves production efficiency. At the same time, the cured ink has excellent performance in terms of wear resistance, water resistance, chemical resistance, etc., ensuring printing The durability of quality enables the printed patterns on the surface of plastic bottles to remain clear and beautiful for a long time.

Summary︰
Plastic hollow containers are widely used in product packaging such as: medicine, cosmetics, detergents, lubricating oil, beverages, daily necessities, and chemical containers. They are generally made of PP, PE PET, PC and other materials by blow molding. More and more large-scale factories use automatic screen printing machines to print their products. Since this kind of screen printing machine is connected like a long queue, it is vividly called a silk screen printing dragon. Screen printing dragon is the first automatic screen printing machine to enter the market, and it also occupies the largest share in the market. Now it is also the most standardized automatic screen printing machine. Its main structure is: 1) Feeding conveyor belt: It is a conveyor belt. The operator can place the product to be printed on the conveyor belt. The conveyor belt can automatically transfer the plastic bottle to the feeding position, and the feeding nozzle of the machine will suck the bottle To the transfer table of the screen printing machine. Some users will request to customize the automatic feeding chute, and the bottles can be put into the feeding chute, and the bottles will be automatically arranged into the feeding conveyor belt. 2) Pre-press device: The pre-press device includes orientation adjustment of plastic bottles and product surface treatment, such as flame treatment, plasma treatment, coating of PP oxidant, etc. 3) Printing system: The printing system of the automatic screen printing machine is similar to the printing device of the semi-automatic screen printing machine, but it has more functions. In order to improve the printing efficiency and precision, more and more movements of the screen printing device are controlled by servo motors, pneumatic components More and more international famous brands are used for electronic and electronic components, and the main parts of the machine are also processed with high-strength steel instead of aluminum profiles. The wear resistance and service life of steel materials are much better than aluminum profiles. 4) UV drying system and UVLED drying system: For continuous high-speed screen printing, an important option to ensure that the screen is not blocked is to use UV ink, which will basically not dry to the screen surface and affect printing unless it is irradiated by ultraviolet rays. 5) Unloading system: If you do not arrange the printed products, you only need one unloading conveyor belt, but if you need to arrange the printed products, the machine will be equipped with a manipulator and placed regularly on the conveyor belt. Now more and more users choose automatic multi-color container screen printing machine, which actually integrates three processes of flame treatment, silk screen printing and curing, which not only greatly reduces the labor intensity of the operator, but also greatly improves the printing quality of the product. Factories that are accustomed to semi-automatic screen printing machines have also begun to upgrade and purchase brand new screen printing machines to expand production capacity.
