Overview
The Putty Filler + Single Roller Coater is an integrated coating solution that combines a putty filling station with a precision single roller coating unit in one streamlined system. This combination machine is specifically designed to first fill surface imperfections on uneven flat panels with putty or filler, and then apply a uniform coating of primer, paint, or varnish in a single pass. By automating both filling and coating processes, it eliminates manual putty application, significantly improves production efficiency, and ensures a consistently smooth, high-quality finish.
The system is built for seamless integration into automated finishing lines, working in conjunction with sanding machines, dust cleaners, UV curing ovens, and conveyors to form a complete, high-efficiency production line.
Applications
The Putty Filler + Single Roller Coater is suitable for a wide range of flat panel materials across multiple industries:
The machine can handle various coating materials including PU, NC, UV-curable, and water-based paints, with recovery systems to minimize waste.
Working Principle
The machine operates through two sequential stages integrated into one continuous process:
Stage 1 – Putty Filling:
The putty filling unit applies filler material onto the surface of uneven flat panels, filling pores, cracks, knots, and other surface imperfections-. Excess putty is scraped away and recovered for reuse, ensuring minimal material waste.
Stage 2 – Single Roller Coating:
After filling, the workpiece proceeds to the single roller coating section. A distributing wheel evenly transfers coating material onto the coating roller (rubber roller or laser-engraved roller). The coating roller then applies a uniform layer of paint, primer, or varnish onto the product surface. The result is a smooth, evenly coated surface ready for subsequent drying or curing.
The coating roller, distributing roller, and conveyor are each driven by motor reducer and frequency converter systems, allowing precise control over coating thickness and application quality.
