How does plywood sander work
Plywood sanding machine is a kind of mechanical equipment used to improve the surface quality of plywood. Its working principle is mainly based on high-speed grinding and precise control to ensure the smooth and flat effect of the plate.
Sanding mechanism
The core component of the sander is the high-speed rotating sand belt or sand roller, and the surface is covered with different meshes of sand (coarse sand, medium sand or fine sand). When the plywood is conveyed to the sanded area through the conveyor belt or roller, the sanding belt is driven by the motor at high speed to grind the surface of the plate and remove burrs, glue marks and uneven parts.
Pressure regulating system
The sander is equipped with a pressure adjustment device, which can adjust the pressure of the sanding roller or pressing plate according to the thickness of the plate and sanding requirements. Excessively high pressure results in excessive grinding and low pressure affects the sanding effect, so precise control is required to ensure even grinding.
Multi-pass sanding
High-quality plywood usually undergoes multiple processes of coarse sand, medium sand and fine sand. Coarse sand is used to quickly remove large defects, medium sand is used to further flatten the surface, and fine sand is used for fine polishing, so as to finally make the plate surface smooth and fine and meet the requirements of subsequent processing.
Dust removal system
A large amount of wood chips and dust will be generated in the sanding process. The equipment is equipped with a built-in dust collector to timely remove the debris through the fan and the pipeline to keep the working environment clean and avoid the dust affecting the sanding accuracy.
Plywood sanding machine combines high-speed grinding, pressure regulation and multiple sanding to realize efficient and accurate processing of plates and ensure stable quality of finished products.
