Plywood Putty Spreader Machine

The plywood putty spreader machine is a specialized equipment designed for applying putty evenly onto plywood surfaces before sanding and finishing. In the plywood manufacturing process, small cracks, holes, or surface defects are common. Applying putty is essential to fill these imperfections, ensuring that the final panel surface is smooth, uniform, and suitable for lamination or painting. Traditionally, this task requires high manual labor and is time-consuming, but with an automatic putty spreader, efficiency and consistency are greatly improved.

This machine adopts advanced mechanical structure, precise rollers, and automated control systems to guarantee uniform putty application on single or double surfaces of plywood panels. It is widely used in plywood, block board, particle board, and decorative panel production lines. With its reliable design, it helps reduce labor intensity, enhance panel quality, and improve production efficiency for wood processing factories.

Technical Parameters

(The following values may be adjusted based on model and customization.)

Working Process

• Panel Feeding: Plywood or panels are placed on the conveyor feeding system.
• Surface Detection: The machine ensures panels are aligned and leveled for accurate putty spreading.
• Putty Application: Through the spreading roller system, putty is evenly applied to the surface. The thickness can be adjusted according to surface requirements.
• Double-Sided Processing (Optional): The machine can apply putty simultaneously on both top and bottom surfaces for higher efficiency.
• Leveling and Scraping: Excess putty is scraped and distributed evenly, filling surface pores and cracks.
• Automatic Conveying: Panels are transferred to the next station, usually drying or sanding.

This workflow ensures continuous, stable, and precise putty application with minimal operator intervention.

Main Components & Functions

• Feeding Conveyor: Ensures smooth and stable panel transport into the machine.
• Spreading Rollers: High-precision rollers evenly distribute putty on the surface. They can be adjusted for thickness and width.
• Scraper System: Removes excess putty and levels the surface for uniform coating.
• Putty Supply System: Automatically supplies putty from the storage tank to the spreading unit. It maintains consistent material flow and prevents interruptions.
• Control Panel (PLC System): Provides easy operation and adjustment of speed, putty thickness, and working parameters.
• Frame Structure: Rigid and durable steel frame ensures long-term stability and minimal vibration.
• Optional Double-Side Unit: Adds efficiency by coating both surfaces simultaneously.

Advantages

• High Efficiency: Replaces manual labor and increases production capacity significantly.
• Uniform Quality: Ensures consistent putty thickness and smooth surface, reducing sanding workload later.
• Adjustable Design: Suitable for various panel sizes, thicknesses, and putty types.
• Labor Saving: Reduces workforce requirements and minimizes human error.
• Strong Durability: Robust construction with reliable components ensures long service life.
• Energy Saving: Optimized motor and roller systems reduce energy consumption while maintaining high output.
• Easy Operation: User-friendly PLC interface allows quick setup and monitoring.
• Low Maintenance: Simple structure and high-quality components lower the frequency of breakdowns.
• Wide Application: Compatible with plywood, block boards, decorative panels, and other wood-based boards.
• Cost-Effective: Improves final product quality, reduces waste, and increases profitability.
