The coating thickness of a curtain coating machine is determined by both the liquid flow rate and the conveying speed. If the flow rate is too high and the speed too slow, the coating thickness increases, and the surface tension is insufficient to support gravity, easily leading to sagging.

Furniture coating requires high precision and consistency. Single-roller or double-roller structures often cannot meet the complex process requirements; therefore, most furniture factories choose multi-roller UV Roller Coating Machines.

The conveyor speed of the UV Dryer Machine directly determines the amount of time the substrate receives light. If the conveyor is too fast, the curing time will be insufficient; if it is too slow, it may over-cur or yellow.

A UV Roller Coating Machine in a furniture factory typically requires only 2-3 people to operate efficiently. Among them: • 1 person responsible for equipment control and process monitoring; • 1 person responsible for material feeding and receiving; • Depending on production volume, one additional person can be added for assisting with handling and inspection.

Step 1: Shut down the equipment and power system. Step 2: Drain the paint system. Step 3: Clean the roller surface. Step 4: Clean the scraper system. Step 5: Clean the paint tank and conveying system. Step 6: Clean the pipes and pump.

From a coating process perspective, a UV Roller Coating Machine is perfectly suitable for small-batch production, provided that the company correctly configures the equipment parameters and production process.

When the speed difference between the metering roller and transfer roller of a UV Roller Coating Machine is too large, shear bubbles can form in the coating layer. Especially under high-viscosity coating conditions, these bubbles are more difficult to escape, resulting in "pinhole" or "bulge" defects during curing.

Although theoretically UV Roller Coating Machines should not scratch furniture boards, in actual production, surface scratches, lines, or abrasions can still occur if the equipment or operation is improper.
