A UV printer is a mechanical device capable of emitting strong ultraviolet rays that can be utilized. It has been widely used in flooring, furniture, wooden doors, printing, electronics, building materials, machinery, and other industries. The type and style of UV curing machines vary depending on the product in which it is cured, but its ultimate purpose is to cure UV paint or UV ink. The UV printer consists of five parts: a light source system, a ventilation system, a control system, a transmission system, and a cabinet.
The light source part is mainly composed of a UV lamp, a lamp cover, a ballast, a trigger and the like. At present, domestic UV machines mainly use high-pressure mercury lamps as UV light sources. High-pressure mercury lamps are relatively inexpensive and have high peaks in the range of 343~380nm, so they have a wide range of applications. There are many manufacturers of high-pressure mercury lamps in China, and the manufacturing process is very different. The main difference is that the lamp materials used are generally between 600-1000 hours. After the service life of the UV lamps becomes due, it is recommended to replace them immediately. The UV light will weaken and affect the curing effect. In addition, the number and power of the lamps contained in a UV printer are not as high as possible. They should be selected according to the actual needs of their own production. Otherwise, the power of the UV lamp will be too high or too low for the curing effect of the product.
The ventilation part is mainly composed of a fan, an air inlet duct, a windshield and the like. For different UV printers, fans are different. The power selection of the fan is determined according to the power of the UV lamp and the space of the cabinet. If a high-power UV lamp is used, the use of a low-power fan will cause heat dissipation for high temperatures will shorten the life of a series of parts.
If you want to control the temperature precisely, the UV printer should use a temperature controller. When purchasing a UV printer, you should carefully inquire about the details of the ventilation system to ensure that the UV machine has a good ventilation section. Because it is not easy to repair and modify when the entire ventilation system has a problem.
The control part includes leakage protector, motor overload protection, control line insurance, fan motor insurance, UV lamp ammeter, lighting timer, digital temperature controller, power indicator, start/stop switch, UV lamp half-power setting, etc. The electrical control part is made of French Schneider Electric products with high sensitivity and durability.
The transmission part is generally composed of a geared motor, a frequency converter, a conveyor belt, a chain or a drum. There are many brands of inverters and geared motors on the market, and the quality is different. It is recommended that the manufacturers pay attention to the resolution when purchasing a UV printer. It is best to use inverters and geared motors with reliable quality, especially inverters, whose repair rate is oftentimes extremely high.
The UV chassis is probably the most overlooked part, and the machines with the same shape are different. The internal structure may vary widely. Most of the poor quality UV machines have failed in the design of the cabinet, internal lines of which are messy and ventilation are poor, and there is no interlayer, which will have a direct impact on the performance of the UV machine and cause inconvenience to subsequent maintenance.
Therefore, when purchasing a UV printer, you are advised to pay attention to the above-mentioned points in order to get a good deal.
