SPA screen printing machine

Fully automatic multi-color disc UV screen printing machine

Basic introduction:

UVMulti color screen printing machine is a novel new generation screen printing machine both domestically and internationally,Leading technology and global innovation. This machine integrates machinery, electricity, gas, and light into one,Digital fully computerized automatic control,Smooth operation at high speed and accurate positioning,Successfully solved issues such as ink difficulty drying, inability to achieve one-step multi-color continuous printing, low efficiency, poor material adhesion, and unsatisfactory printing resultsUVCommon difficulties in printing. This device is particularly suitable for cigarette bags, color boxes, metal sheets, soft and hard plastic sheets (such as...)PVCThePPThePCThePETTheEVATheAPETThePETG）Hard and brittle materials such as plastic leather, wooden boards, glass, ceramics, cardboard, as well as other materials such as clothing and leather fabrics (nylon fabric, Teflon, high height fabric, polyester fabric, etc.)PVCSkinPUHigh precision continuous color printing of special sheets such as leather.

This series of devices independently possesses multiple utility model and design patents（ZL .9）All indicators have reached the international advanced level, and the products comply with European standardsCESafety standards are new industrial products in Zhejiang Province.

Features:

1．UVAdvanced technology that enables printing（500*500MM）In2Rapid and effective photo fixation within seconds, multi-color automatic continuous printing, the world's first.

2．UVThe body has an ultra high speed air supply and temperature regulation circulation system, with strong heat dissipation ability and automatic regulation, which is efficient and energy-saving.

3The pallet rotates automatically, balances at high speed, and the workstation positioning is accurate

4Each color scraper and print head can work separately with a standard electric shock disconnect device, variable frequency speed regulation, and micro air volume lifting

5The main rotation adopts imported servo motor series,Touch based human-machine interface centralized control system.

Working principle and characteristics of UV oven:

1UVCuring principle:

Adding a photoinitiator (or photosensitizer) to a specially formulated resin, which absorbs ultraviolet light（UV）After high-intensity ultraviolet light in the UV curing equipment, active free radicals are generated, which trigger polymerization, cross-linking, and transfer reactions, resulting in resin ink/Paint is not available1Transform from liquid to solid within seconds.

IIUVCuring lamp:

1.Currently used in industryUVThe equipment light source is mainly gas discharge lamps. According to the pressure of the gas inside the lamp, it can be divided into low pressure, medium pressure, high pressure, and ultra-high pressure. Our company uses high-pressure lamps.

2.High voltage lamps can generate strong radiation310nmThe365nmThe410nmCharacteristic ultraviolet light of equal wavelength（UV）Visible and infrared light（IR）Among them365nmThe wavelength of the main peak is commonly used in various countries around the world for curing dry bathsUVLamp refers to365nmThe high-pressure mercury lamp. due to365nmSpectral bands suitable for commonly used photopolymerization inks/paint,So when choosing a generalUVIt is necessary to conduct a photopolymerization test first when using photopolymerization equipment to verifyUVDoes the wavelength of the machine meet the optical solid requirements.

3.UVReasonable refraction of light sources and their effectsUVThe filtering of stray light in the lamp tube is quite important, otherwise it will affect the light fixation effect.

4.averageUVMachine fixed ink/The required power for paint is80-120w/cmExcessive light solid energy can cause ink/The brittleness of paint and the low photopolymerization energy will not achieve the photopolymerization effect.

5. UVWhile the lamp emits ultraviolet rays, it also generates a large amount of heat, causing the temperature inside the machine to continuously rise. Therefore, in the light curing machineUVIt is necessary to install a ventilation device above the lamp tube, and to discharge the ozone generated during the curing process outdoors through the ventilation duct to achieve the purpose of cooling, so as to adapt to work with thin coating or high temperature requirements..

3、 Our companyUVThe main features of the oven are:

1.The oven works as a whole, with a beautiful appearance, lightweight volume, and space saving.

2.Optional lamp power professional, using imported light source reflector, maximum refractionUVLight.

3.Equipped with a specially designed quartz glass filter, it can filter out various types of stray light,And equipped with advanced ventilation and heat dissipation devices to ensure that the workpiece is not affected by temperature,Successfully solved issues such as difficulty in drying ink and paint, poor material adhesion, low efficiency, and unsatisfactory printing resultsUVThe common difficulties in printing have strengthened the drying and curing effect.
