1. Material preparation section. The raw materials of ordinary particleboard production line are sent to the wood chip silo for transitional storage after chipping and screening. The wood chips are sent to the chipper by conveyor for wood chip preparation, and the prepared wood chips are sent to the wet wood chip silo by conveyor for transitional storage.
2. Drying, sorting and grinding section. The wet wood chips are sent to the rotor wood chip dryer by conveyor for drying. The dried wood chips are sent to the core layer dry wood chip silo for transitional storage through the wood chip sorting (screening). The qualified core layer dry wood chips are sent to the core layer dry wood chip silo for transitional storage by conveyor. The oversized wood chips are sent to the surface layer dry wood chip silo for transitional storage after being polished by the grinder.
3. Gluing and sizing section. Qualified surface and core layer dry shavings are measured by conveyors and shaving metering silos and then sent to the glue mixer. At the same time, the glue supply section sends the glue required by the process to the glue mixer. The shavings and glue are fully stirred by the surface and core layer glue mixer to achieve the effect of uniform mixing and full glue application.
4. Paving hot press molding section (production line with an annual output of more than 30,000). The shavings after gluing are sent to the mechanical grading paving machine by a belt conveyor, and the mechanical grading paving unit paves out uniform and flat slabs. The slabs are sent to the loading cage of the loading machine through permanent magnetic iron remover, pre-pressing machine, longitudinal sawing machine, cross-cutting saw, acceleration conveyor, weighing conveyor, storage conveyor, loading conveyor and other processes. The loading cage sends the slabs to the multi-layer hot press for hot pressing. The rough board formed by the multi-layer hot press is pushed to the unloading machine by the loading trolley tray at the same time.
5. Post-processing section. The rough board staying in the unloading machine is sent to the cooling board conveyor by the unloading conveyor, and then sent to the cooling board machine by the cooling board conveyor for cooling. After staying (cooling) in the cooling board machine, the rough board is sent to the vertical and horizontal cutting machine by the cooling board conveyor for trimming and segmentation, and finally transported to the lifting platform for stacking by the dry board conveyor.
6. Sanding section. The particleboard after cooling and stacking is sent to the sanding production line for sanding, sorting and storage.
