[0040] A reset switch 19 and a pneumatic locking latch 20 are respectively provided on both sides of the back side of the coating machine body 1 .

[0041] Lamp source temperature: UV lamp cooling system temperature control, the cooling temperature can be appropriately adjusted according to the light source intensity and ambient temperature.

[0042] UV light source: It is the control switch of UV light source. When the switch is turned to the "I" position, it is on and the indicator light below will light up. When it is turned to the "O" position, it is off. (Note: After this switch is pressed, other operating switches of UV light will work).

[0043] Light source adjustment: Adjust the intensity of the UV light source. It can be adjusted appropriately according to factors such as the thickness of the coating, the material of the printed product and the speed of the material. Turning the knob clockwise will increase the intensity of the light source, and turning it counterclockwise will reduce the intensity of the light source.

[0044] Power isolation switch: The main power switch. Turn on the isolation switch and power on the whole machine before it can enter the working state. After the work is completed, shut down the machine and the isolation switch must be turned off.

Press it again to turn off the UV lamp. (Note: The temperature of the UV lamp is relatively high, so the UV lamp must be turned on while the printed product is moving. If you want to stop the material from moving, you should turn off the UV lamp first to avoid burning the printed product).

[0052] Paint heating: When the ambient temperature is low, the paint becomes viscous, which can easily lead to poor fluidity, increased viscosity, and uneven coating. The paint heating device can be turned on to increase the temperature of the water in the heating tank, and then the heat is transferred to the paint tank to heat the paint to the display set temperature.

[0053] The reading on the display panel is the current temperature of the water in the heating tank, and the reading below is the set heating temperature, which can be adjusted up and down by buttons (generally set to 60°C). After setting the target temperature, press the red paint heating device start button, and the paint will start heating until it reaches the set temperature and maintains a constant temperature. Generally, the water and paint should be fully heated before production can begin.

[0054] Working principle:

[0067] Coating and curing

[0068] Coating unit

[0069] The coating unit is mainly composed of auxiliary rollers, metering rollers, guide plates, scrapers, etc. If the downtime exceeds 30 minutes, please clean the coating unit first. It is best to use alcohol to clean the coating unit to prevent other organic solvents from contaminating the coating. When using alcohol, fireworks are prohibited.

[0070] Curing and drying unit

[0071] The main function of the curing and drying unit is to solidify the coating attached to the surface of the finished product to ensure that the surface of the finished product is dry. The curing and drying unit is mainly composed of UV lamps and cooling systems.

[0072] You can choose UV lamps according to different coatings, and the wavelength of UV light is determined by the coating.

[0073] Cooling system: UV-LED lamps will generate extremely high heat after startup. In order to prevent the internal heat from being too high and causing the product to be scorched or burned, a heat dissipation system is added, which also discharges the heat of the curing and drying unit.

[0074] Note: Please clean the coating unit after shutdown; do not cut off the isolation switch immediately after shutdown. The isolation switch can be cut off only after the curing and drying unit cools down.
