With the development of printing industry, the continuous deepening of screen printing UV printing technology, different process requirements and production conditions have different technical requirements for screen printing UV curing machine screen printing UV dryer screen printing UV curing machine, silk screen printing UV curing machine screen printing on the market UV dryers There are many varieties of screen printing UV curing machines. How to choose the UV equipment that is suitable for the specific process requirements and production conditions is a key issue. The following analysis of UV equipment selection is based on different process requirements and production conditions.
I. Variety and name
Screen printing UV light curing machine, silk screen UV curing machine, silk screen UV drying machine referred to as UV machine, are the same type of equipment used UV light (UV lamp) UV ink, UV varnish, UV coating for light solid drying drying Different fields have different names, and the varieties are divided into conventional UV machines and low-temperature high-speed UV machines.
Second, semi-automatic slow screen printing, automatic high-speed screen printing
Conventional semi-automatic silk screen printing generally prints monochrome patterns, the production speed is slow, and there is no ordinary printing that multi-color printing overprinting process requirements, automatic high-speed printing is used in high-end color printing packaging production, production process requires multi-color overlay accurate, high High-end printing efficiency.
Third, conventional UV machine, low-temperature high-speed UV machine
The conventional UV machine is a UV device suitable for printing in medium and slow speed. The UV light source used is an ordinary "high temperature and low intensity" UV lamp with a drying speed of 1000 sheets/hour and 2000 sheets/hour. Due to the low intensity and high temperature of the UV lamp, the UV curing temperature will increase exponentially when the UV lamp power is increased. This is not suitable for increasing the photo-solid speed. It is more suitable for screens with lower printing requirements and slower drying speeds. Printing production. The low-temperature high-speed UV machine is a UV device with a wide range of applications and advanced process functions. The UV light source used is a "low-temperature and high-intensity" new-generation UV lamp, which has fast light and solidity, low temperature, energy saving and energy saving, and can be adapted to 2000-4000. Zhang / hour printing speed, printing overprinting requirements of high-speed automated screen printing production.
Fourth, UV lamp (low temperature high intensity UV lamp, high temperature and low intensity UV lamp)
The same power UV lamps used in UV machines can be divided into imported low-temperature high-intensity UV lamps and domestic high-temperature low-intensity UV lamps. Imported low-temperature high-intensity UV lamps are high-purity light-emitting electrodes with a precise proportion of luminous gas. ,The low-current high-pressure mercury lamp produced by high-end technology can be used in conjunction with the power supply that matches the parameters. It can emit 365nm low-temperature high-intensity ultraviolet light suitable for the UV ink, and the luminous intensity is lower than that of the conventional high-temperature low-intensity UV lamp with the same power. More than 100% high, more than 40% lower light emission temperature, is a new generation of advanced UV lamps. Conventional high-temperature low-intensity UV lamps use lower purity of the light-emitting electrode, and the manufacturing process is not strict. A large current is necessary to enable the UV lamp to start. The current has a large heat-generating temperature and a low luminous intensity, which is a relatively backward UV lamp.
Fifth, high-quality low-temperature high-speed UV machine
Shantou Huanan Machinery Co., Ltd. develops and manufactures advanced equipment for low-temperature high-speed screen printing UV machines for the process requirements of automatic high-speed screen printing UV printing, uses imported advanced low-temperature high-intensity UV lamps, and is equipped with an advanced UV lamp cooling system to enable UV light-solid temperature control. About 50°C at room temperature, the solid-state drying speed is 5000 sheets/hour, which is in line with the requirements of high-speed printing and multi-color printing. Shantou City, South China Machinery Co., Ltd. production of dual-licensing silk screen printing low-temperature high-speed UV machine products, can be imported and domestic various types of automatic high-speed screen printing machine supporting products from the advent of the Shanghai area has been a number of brand-name automatic screen printing machine factory Supporting, widely used in many large cigarette pack printing plants and color printing plants, has become a well-respected brand in the industry.
