This production line is specifically designed for pine and various softwood raw materials, taking into full consideration the characteristics of pine such as soft texture, relatively high resin content, and frequent knots. Key processes including peeling, drying, glue spreading, and hot pressing have been optimized accordingly.
Pine is one of the most commonly used raw materials in global plywood production, valued for its abundant supply, stable pricing, and excellent workability. This production line efficiently transforms pine veneers into high-quality plywood through precise process control, serving a wide range of applications including furniture manufacturing, concrete formwork, and packaging materials.
Main Equipment of the Production Line
1. Pine-Specific Log Peeling Machine : Equipped with cutting tools featuring optimized blade angles to reduce surface fuzzing and increase veneer yield; automatic centering system adapts to the curvature characteristics of pine logs.
2. Mesh Belt Veneer Dryer : Utilizes low-temperature, slow-speed drying to prevent cracking and warping of pine veneers; zoned temperature control ensures uniform moisture content.
3. Automatic Clipping & Splicing Machine : Automatically detects and removes defects such as knots and splits in pine veneers; splices small pieces into full-size sheets using finger jointing or stitching.
4. Pine-Specific Glue Spreader : Optimizes glue roller material and pressure to ensure even adhesive penetration, addressing the higher resin content of pine; automatic glue amount adjustment reduces consumption.
5. Automatic Lay-up Line : Automatically assembles glued pine veneers in odd-number layers with cross-grain orientation; optional positioning system ensures neat mat formation.
6. Pre-press Machine : Pre-compresses pine veneer mats to prevent shifting during transport.
7. Multi-opening Hot Press : Features a balanced hydraulic system for uniform pressure distribution, suitable for the compression characteristics of pine; temperature and time parameters optimized for pine adhesive curing curves.
8. Four-Side Edge Trimmer Saw : CNC servo-controlled, precisely trims all four edges of pine plywood to ensure accurate dimensions.
9. Sanding Machine : Multiple sanding units finely finish pine plywood surfaces, removing fuzz and enhancing flatness and coating performance.
10. Automatic Sorting & Stacking System : Automatically grades and stacks finished panels through online thickness and surface defect inspection.
Pine
Working Process
1. Log Preparation : Pine logs are debarked and softened through steaming; steaming duration is adjusted based on pine density and moisture content.
2. Peeling : Pine logs are peeled into continuous veneer strips with controlled thickness uniformity.
3. Drying : Mesh belt dryer applies low-temperature, slow-speed drying to achieve veneer moisture content of 8%-12%.
4. Clipping & Splicing : Defective sections such as knots and splits are removed, and veneers are spliced into full-size standard sheets.
5. Glue Spreading : Phenolic or urea-formaldehyde adhesive is evenly applied on both sides; glue amount is adjusted to suit the resin characteristics of pine.
6. Lay-up : Automatic assembly in odd-number layers with adjacent layers oriented perpendicularly.
7. Pre-pressing : Short-term pre-compression for preliminary mat shaping.
8. Hot Pressing : Multi-opening hot press cures the adhesive under high temperature and pressure to form pine plywood panels.
9. Trimming : Rough edges are trimmed to achieve finished dimensions.
10. Sanding & Sorting : Surfaces are sanded, followed by automatic inspection, grading, stacking, and packaging.
Truck & Container Flooring:Lightweight panels for transportation applications.
