There are many drying methods for ink printed on the product, and UV drying is a common one: Photosensitive resin is used as a binder in UV ink, which will cause a cross-linking reaction under the irradiation of ultraviolet rays, thereby triggering the curing of the ink. UV curing needs to use As for the UV curing machine, a separate UV curing machine can be used with a screen printing machine and an offset printing machine. There are also quite a few UV curing systems installed on the automatic screen printing machine. The UV curing machine is mainly divided into a light source system and a conveyor belt. The product will enter the light source irradiation unit through the conveyor belt to complete the curing process. UV curing machine is mainly divided into surface UV curing machine and flat UV curing machine
1. Working principle
• Flat UV curing machine mainly uses ultraviolet light (UV) to cure the ink printed by the offset printing machine. There is a UV lamp inside (UV-LED light source in UV-LED curing machine). When the printed product passes through the curing machine, the ultraviolet light emitted by the light source irradiates the ink layer. Under the stimulation of ultraviolet light, the photoinitiator in the ink produces free radicals or cations. These active substances trigger the polymerization reaction of monomers and prepolymers in the ink, so that the ink quickly changes from liquid to solid, thereby achieving the curing of the ink.
2. Features of high-speed adjustable and variable frequency speed regulation
• High-speed adjustable: The speed of the offset printing machine will change under different printing tasks, which requires the matching UV curing machine to adapt to different speeds. The high-speed adjustable function enables the curing machine to be flexibly adjusted according to the printing speed of the offset printing machine. For example, when the offset printing machine is printing at high speed, the curing machine can increase the power or speed up the conveyor belt accordingly to ensure that the ink is fully cured in a short time; when the offset printing machine is running at low speed, the curing machine can also reduce the power to avoid over-curing, thereby achieving the purpose of energy saving and ensuring printing quality.
• Frequency conversion speed regulation: The speed of the curing machine is adjusted by frequency conversion technology. The frequency conversion speed regulation system can accurately control the speed of the motor, and then adjust the running speed of the conveyor belt inside the curing machine. This can not only match the speed of the offset printing machine, but also achieve smooth transition when starting and stopping, reduce the impact on the equipment, and extend the service life of the equipment. Moreover, the frequency conversion speed regulation can also be flexibly adjusted according to factors such as the material of the printed matter and the type of ink, making the curing process more accurate.
3. Application advantages
• Improve production efficiency: It works well with high-speed offset printing machines, can quickly cure ink, shorten the drying time of printed matters, and make the entire printing process more efficient. For example, in the packaging and printing industry, it can quickly process a large number of flat printed matters, such as packaging boxes, labels, etc., which reduces the residence time of printed matters in the workshop and improves turnover efficiency.
• Ensure printing quality: Accurate speed regulation and UV curing can ensure that the ink is fully cured, making the color of the printed pattern more vivid and firm. The cured ink has good wear resistance, chemical resistance and scratch resistance, which can effectively prevent the pattern from being damaged during subsequent processing, transportation or use, and improve the quality and stability of the printed product.
• Energy saving and environmental protection: The variable frequency speed regulation function can adjust the power according to actual needs, avoiding unnecessary energy waste. At the same time, compared with traditional thermal curing technology, UV curing technology does not produce volatile organic compounds (VOCs) and is more environmentally friendly.

Function |
|
Application: | The UV curing machine is used for curing UV ink, and the essential requirement for the UV curing machine is to dry the UV ink thoroughly within a specific time. Generally, UV dryer is not used alone. It is usually used with offset printing machine, coating machine and screen printing machine. The speed of offset printing machine is faster, and the speed of matching UV curing machine is required to be faster. If the speed of UV curing machine matches the offset printing machine , You can directly connect the offset printing machine and the UV curing machine. For the coating machine, since the thickness of the coating determines the speed of the UV curing machine, the speed adjustment of the UV curing machine should have a larger range. In the special printing industry, UV curing machines are most often used with screen printing machines. The speed of fully automatic flat screen printing machines is also very fast. It is also possible to connect fully automatic screen printing machines and UV curing machines. Semi-automatic screen printing machines are more suitable for UV curing machines. Complicated, the semi-automatic flat screen printing machine usually prints intermittently, and the UV curing machine needs to be equipped with a robot, which can reduce the labor intensity of the operator, and the paper can also be placed on the UV curing machine manually. The most important parameter for choosing a UV curing machine is to consider the lamp power of the UV curing machine and the size of the conveyor belt. The product must pass through the conveyor belt smoothly, and the ink can be cured quickly after passing through the curing unit. |
