Key parts and functions of edge banding machine
Edge banding machine is a specialized equipment used in furniture manufacturing for edge banding of boards. It mainly uses hot melt adhesive to bond edge banding strips such as PVC, ABS, and wood veneer to the cutting edges of boards. Its core components and functions are as follows:
Feeding position: The starting point of sheet conveying, usually equipped with conveyor belts or rollers to ensure smooth entry of the sheet into the machine.
-Key components:
-Conveyor belt/roller: Convey the sheet at a constant speed to maintain feeding stability.
-Guiding device: Adjust the position of the board to ensure edge alignment.
Glue application area: Apply hot melt adhesive evenly to the edge of the board.
-Key components:
-Glue pot: Heat and melt the glue particles (usually controlled at a temperature of 180-220 ℃).
-Glue wheel: Rotate to apply glue, and the amount of glue can be adjusted by air pressure or mechanical means.
-Scratcher: Control the thickness of the adhesive layer to avoid glue overflow.
Edge banding conveyor: Automatically transport the edge banding to the edge of the board.
-Key components:
-Material rack: stores edge banding rolls and supports automatic unwinding.
-Cutting device: Cut the edge banding strip (some models can preset the length).
Pressing part: Press and bond the edge banding strip to the edge of the board.
-Key components:
-Pre press wheel: preliminarily fix the edge banding to prevent displacement.
-Main pressure wheel/roller: High strength pressure to ensure firm adhesion.
-Lateral pressure device: Apply lateral pressure to irregular plates (such as curved edges).
Edge trimming area: Cut off the excess part of the edge banding to make the edge flat.
-Key components:
-Rough knife: Quickly remove most of the excess edge banding.
-Precision knife: Fine trimming the edges to a smooth finish (usually using high-speed rotating blades).
-Tracking knife: Automatically adjust the cutting position according to the thickness of the board.
Polishing area: Further polish the edge sealing area to enhance glossiness.
-Key components:
-Polishing wheel: cloth wheel or steel wire wheel, used to eliminate burrs after trimming.
Discharge location: Complete the output of the edge sealed board.
-Key components:
-Discharge conveyor belt: to receive finished products and avoid scratching the surface.
-Stacking rack: Automatic sorting of boards (equipped with high-end models).
Control system: Coordinate the operation of various components and adjust parameters.
-Key components:
-PLC/Touch Screen: Set parameters such as temperature, speed, pressure, etc.
-Sensors: detect the position, adhesive amount, faults, etc. of the board.
Auxiliary system: Remove debris after trimming.
-Vacuum nozzle: Collect dust and keep the working environment clean.
-Cooling system: Some models are equipped with air or water cooling to accelerate the curing of glue.
Difference in edge banding machine types
-Manual edge banding machine: requires manual feeding and is suitable for small batch production.
-Automatic edge banding machine: Fully automatic assembly line, suitable for large-scale processing.
-Laser edge banding machine: uses laser activated edge banding with adhesive layer, no glue line, commonly used in high-end furniture.
