The Main Process Flow Of Particleboard Production Line

The main process flow of particleboard production line is: material preparation → chipping → flaking → drying + sorting + glue mixing → paving + prepressing → cross cutting → board loading → unloading +cooling + sawing + sanding + inspection and storage. This process is divided into the following sections. In the material preparation section, the spare raw materials are chipped by the chipper and sent to the wood chip bin for transitional storage. The wood chips are then sent to the chipper to be processed into shavings, and the shavings are sent to the wet shavings bin for transitional storage. (Industrial shavings and sawdust can also be used, and they can be stored in transition after screening) In the drying and sorting section, the wet shavings are sent to the rotary dryer for drying. The dried shavings are screened by the swing screen. The qualified core and surface dry shavings are sent to the core and surface dry shavings bins for transitional storage. The oversized shavings are crushed or polished and then enter the swing screen for sorting. In the glue mixing and gluing process, qualified core and surface shavings are evenly transported to the glue mixer. At the same time, the glue supply equipment adds the glue required by the process into the glue mixer. The core and surface shavings and glue are fully stirred by the glue mixer to achieve the effect of even mixing. In the paving and hot pressing process, the shavings after gluing are transported to the paving machine, which paves out flat and continuous bulky slabs with a gradient structure and a required thickness. Then, they are made into bonded slabs with a certain strength through the pre-pressing machine, the edge saw, and the cross-cutting saw. They are sent to the loading machine through the slab conveyor and the pusher. The loading machine sends the slabs together into the hot press to be pressed into particleboard. At the same time, the rough edged boards that have been hot pressed in the hot press are pushed out to the unloading machine by the pad of the loader. The rough edged boards in the unloading machine of the post-processing section are sent to the cooling plate turning machine through the unloading conveyor and the plate feeding roller conveyor. After staying (cooling) in the cooling plate turning machine, the rough edged boards are transported to the longitudinal and transverse sawing machine by the plate discharging roller conveyor, the centering conveyor, and the roller conveyor to be sawn into 4/X8/ordinary particleboards, and finally transported to the hydraulic lifting platform for stacking. The equipment of the paving hot pressing section and the post-processing section of this production line adopts PLC program control system to realize automatic production, and can also be manually operated. The particleboard is made into a plain board by the sanding particleboard process, and is processed into a sanded particleboard by a sanding machine.
