In the printing and packaging processing industry, the maintenance of equipment and the control of printing machine downtime are very important to increase the profit of the enterprise and increase the return on investment (ROI). This is mainly because most of the equipment in the enterprise is working in several shifts, and downtime for a few hours at an inappropriate time will cause greater losses. Is there a solution to reduce the downtime of printing equipment, the answer is yes, UV curing technology is one of its solutions.
Of course, to improve UV light curing, it is not a strange word. Because UV light curing is a very reliable curing technology that can replace hot air dryers and other drying technologies, it has been widely used in the printing and packaging processing industry.
Advantages of UV light curing technology
One of the main advantages of UV curing technology is that the initial investment of the UV curing system is less. Compared with the investment of hot air drying equipment, the UV curing system can save 80% of the capital in terms of equipment investment. Other advantages of UV light curing are improved production efficiency, improved printing quality, and diversified printing products. In addition, the most prominent advantage is that UV light curing will not emit VOCs (organic volatiles) in the printing workshop and the surrounding environment.
The UV light curing system is easy to maintain and operate, which is also an advantage of UV light curing. The UV light curing system is an advanced technology. When you first use it, you may feel that the maintenance and control of the UV light curing system is a bit complicated. However, in reality, the operation and maintenance of a UV curing system is simple, the downtime is optimized to a minimum, the maintenance of the UV light curing system is easy, and the operation is simple.
The key to maintaining a good UV system is to work out a preventive maintenance plan and maintain the UV light curing system according to this plan. This means that the UV light curing system needs to be thoroughly inspected from time to time, including a thorough inspection from top to bottom. Inspection items include UV bulbs, lamp covers and reflector pads, as well as inspection of mercury relays, capacitors and other electronic components. [next]
UV system maintenance
The UV bulb is the core of any UV system. Proper maintenance and handling of UV bulbs can not only increase the service life of UV bulbs, but also ensure that UV bulbs work at the maximum luminous intensity. The UV bulb is checked once a week, mainly to find out whether there are the following bad signs:
· Expansion of the end of the UV bulb
· The end of the UV bulb is curled
· The end of the UV bulb is white
· Dust and debris deposited on quartz glass
· Ink at the end of the UV bulb
If one of the first three items appears, it means that the UV system needs air conditioning or water conditioning (the cooling of the UV curing system is incorrect).
In addition, it is necessary to handle the UV bulb correctly. The glass of the UV bulb should not be held in hand, but only the ceramic end, or non-burlap gloves. The oil on the skin will stick to the quartz glass. After a while, under the action of heat, the oil will burn the UV lamp. Whenever you need to touch the UV bulb, you can use an alcohol-based cleaning solvent to scrub the UV bulb to remove the grease on the bulb.
The UV lampshade itself also needs to be cleaned and inspected once a week. Carefully check the UV light shielding device to ensure that air can flow into the UV light curing system while ensuring that no excess UV light leaks. The air intake filter should be kept clean and free of dust and debris on its surface. If a quartz plate is used in the UV light curing process, the quartz plate should be periodically cleaned to ensure that the property of transmitting UV light is still effective.
A good UV lampshade should use air filter and valve working mechanism, which can maximize the effectiveness and reliability of the UV light curing system. The filter should be clean and dust-free so that the airflow is not restricted.
The inspection and maintenance of the UV reflector is another simple method to ensure the maximum efficiency of the UV light curing system. For printing and post-press processing applications, UV reflectors are mainly used to focus and expose the dried printed matter to be cured to maximum UV light. Since 75% of the UV light that reaches the surface of the printed product is reflected UV light, it is important to keep the liner clean. When the topcoat of the mirror surface of the reflector is reduced, it should be replaced immediately.
There are many shapes, sizes and structural configurations of UV power supply devices. The transformers of most power supply units are equipped with mercury relays and capacitors in order to control the power output. The more advanced the power output technology provided by the UV light curing system manufacturer, the power supply mode of the UV light curing system can provide unlimited variable output. The PLC equipped with HMI can provide a graphical interface to enable it to control and track the work of the UV light curing system. [next]
Precautions
When you buy a UV light curing system, you should consider the following factors:
· Can the maintenance personnel of your factory handle electronic components easily?
· Is the transformer compatible?
· Can the electric box cool down, and does it have a lot of filtered air?
Considering the above issues before purchasing a UV light curing system can save time and money.
The work steps mentioned above for using and maintaining the UV light curing system sound a bit troublesome, but they are indeed a good way to save time. Make an hour a week to do some preventive maintenance work, record the maintenance log, the printing staff and post-press processing personnel can make their UV light curing system in the best working state, the equipment maintenance and downtime Time is reduced to a minimum. In order to facilitate troubleshooting, operation and maintenance of the UV light curing system, manufacturers of UV light curing systems will provide a control platform that can give users full computer operation control.
In the printing and post-press processing industries, press downtime is inevitable. When UV light curing will increase production efficiency, improve the quality of printed products and realize the diversification of printing services for printing and post-press processing, preventive maintenance measures are a simple way to avoid downtime of the printing machine when it is not suitable. Before purchasing a UV light curing system, remember that the maintenance characteristics of the system must meet the standards of the UV light curing system, so that your company's printing machine downtime will be reduced to a minimum.
