The production process of multi-layer solid wood composite floor is as follows:
1. Surface plate processing section
Log → log cross section is wood section → cooking in cooking pool → veneer cutting by rotary cutter → veneer dryer drying.
Log → log cross section is wood section → large band saw is cut into planing square timber → cooking in digester → planing veneer with planing machine → veneer dryer is used for drying.
Log → log cross section as wood section → large band saw cutting into square timber → drying → horizontal band saw cutting veneer.
The longitudinal veneer plane tangent line is mainly used to plane the veneer with a thickness of 1-3 mm, the transverse veneer plane tangent line is mainly used to plane the veneer with a thickness of less than 1 mm, and the horizontal band saw is mainly used to saw the veneer with a thickness of more than 3 mm.
2. Table, back plate hot pressing and veneering section
Base material gluing → blank assembly → prepressing → hot pressing → multi saw cutting plate → constant thickness sanding → surface polishing → grading → inspection → balance and tempering. Use cold press and multi-layer hot press to paste the surface plate and back plate.
3. Machining section of tenon spring and tenon groove of composite floor blank
The longitudinal tenoning machine tenons the two sides of the composite floor blank → the transverse tenoning machine tenons the two ends of the floor blank.
4. Surface finishing section
Plain plate sanding → primer application and drying → painting (double roller) → drying → primer sanding → finishing coat application → drying → finishing coat application → drying.
5. Graded packaging
Finished product inspection → grading → heat shrinkable film packaging → warehousing.
