Small Table--Style UV Curing Machine

Technical parameter:
1. UV Lamp's power: 2000W
2. UV light power supply: 220V/50 HZ
3. UV illumination energy: 80JW/CM2
4. UV Wavelength range: 280-420mm
5. UV Process shine area: 300× 400mm
6. Conveyer belt size: L1200*W300mm
7. Conveyor belt speed: 10m/min

B. Characteristics
1. It has 2 suits of 2KW independent control UV systems, which can be used interchangeably in order to extend the service life of UV lamp.
2. Teflon belt to bear high temperature.
3. Driven by well-known motor, stepless speed adjustment. The Conveyor speed can be adjusted according to product's characteristics.
4. UV lamp with high-quality light source, long life. It is able to start instant, rapid access to the normal UV brightness.
5. Electrical components are imported from Taiwan(Transformer, starter), precision Control, long life.
6. With ventilation function, it can quickly distribute heat quickly. Well-designed airflow cooling system to ensure that light generated minimum temperature, reduce rate of prodcut's deformation, improve lamp efficiency.
7. UV oven can ventilate and suction air reverse and simultaneously. For thin paper, PVC film, soft PCB, UV silicon gel etc, the UV curing effect is perfect.

C. Major structure
1. Curing light source is made up by ultraviolet light lamp, irradiation devices, transformer etc.
2. Fan heat removal systemelectrodeless speed change, speed controller drive belt.
3. Cooling air circulation system

D. Matters need attention
1. Ink is required to dry quickly after printing, but not at the printing moment when ink is on the screen frame.
2. Drying can not be too rapid. It should based on the phenomenon of trace residues. Ink uniformity adjustment is an indispensable factor for screen printing. If not, will cause trace residues, no ink on the smallest parts of printing product. Don't over dry, too high temperature, too fast heating speed will lead to product deformation, the size of product instability, ink bubble.
E. Test drying time of ink
Make a screen frame with image(width: 15mm, Length: 40mm). Print product with ink to observe ink non-stick with paper. Calculating how long time is needed for ink non-stick with paper. This time is as same as the dring time of ink on such printing product.
F. Electrical control
1. Contect Three-phase four-wire power 380V to electric cabinet which marked with L1, L2, L3, N and t zero-line, a ground wire (less than 4 ohm).
L1--main electric power indicator light
L2-- suction fan Power indicator light
L3--switch of UV lamp
2. Note the direction of calorifier, if it is the opposite direction of marked, then the distributing heat function is unavailable. So you should check the direction is correct.
3. Inspecting the wiring of thermal element to connect sub-off. If loose, make them tightening.
4. When opening lamp, it is better to start lamp 1 firstly. Then start lamp 2 when the electric current of lamp 1 is at about 5-6A stable, so as to avoid lamp cann't light normal because there is large electric current when start two lamps simultaneously.
5. Before opening UV lamp, it is better to start the conveyor belt firstly. This can prevent there still is curing product on the conveyor belt. If product is lighted by UV lamp persistent, the quality will be affected.
G. Maintenance
1. Lubricating joints of equipment, locking screw positioning regular.
2. Check whether there is any open line phenomenon of circuit regular.
3. Preparing some parts(such as UV lamp 2kw)in order to replace when it is damaged. You can measure light intensity by meter measurement of the UV lamp so as to decide when replace lamp.
4. Conveyor belt and related items must be adjusted well.
5. Keep the printing workshop without dust and ventilation
6. When lamp is turned on, staff should wear sunglasses as a protection against the strong UV light.
