Depending on the product type and coating requirements of different companies, a furniture roller coating line typically requires 8 to 15 machines to form a stable and efficient production system. The key equipment required for each process will be analyzed below.

UV roller coating machines have high requirements for coating viscosity, typically controlled between 20 and 40 seconds. If the viscosity is too high, a special thinner can be added appropriately (do not use ordinary solvents) to improve leveling and help expel air bubbles.

According to industry testing data and actual measurement experience, the overall noise level of a standard UV Roller Coating Machine is approximately 75 decibels. This falls within the range of medium-level industrial equipment noise – higher than a typical office environment (approximately 55 dB).

In most normal temperature (20~25℃) production environments, the UV Roller Coating Machine usually does not require long-term preheating. The temperature difference between the machine's metal parts and the environment is not significant, and the fluidity of the UV coating is within a reasonable range.

Basic Configuration (Suitable for small and medium-sized furniture factories) Production line process: • Feeding → Dust removal → Curtain coating machine → Leveling → UV curing machine → Unloading

Ideal workpieces for curtain coating machines typically possess the following characteristics: • High surface flatness • Regular geometry • No obvious depressions or protrusions • Ability to pass through the liquid curtain zone at a constant speed These conditions indicate that curtain coating machines are inherently more suitable for planar or simple geometric shapes.

UV Roller Coating Machines typically require paint viscosity within a certain range (e.g., 25–60 seconds/Ford-4 cup). If the viscosity is too low, the coating cannot form a stable film on the roller surface, and it tends to spread too quickly on the board, causing it to sag due to gravity.

The most common and highly compatible UV paints for roller coating machines include: UV primers, sealers, intermediate coats, high-gloss topcoats, matte topcoats, and clear acrylic systems.

Single Machine Configuration (Basic Type) Suitable for small furniture factories or sample lines, including only: Infeed section + 1 roller coating machine + 1 UV curing machine + Outfeed section. Space requirements are approximately: Length 10–12 meters, Width 4–5 meters, Height over 3 meters.

That adjusting the coating thickness mainly relies on the balance between flow rate, viscosity, and conveyor speed. This means that a curtain coating machine can achieve both thick and thin coatings, provided the parameters are set correctly.
