Brief description of production process
1, shavings preparation section
Wood raw materials are transported to the factory and stacked according to tree species.
Option One:
Short and small materials such as wood and branches are sent to the feeding belt conveyor of the drum chipper. The qualified wood chips cut by the chipper are sent to the wood chip silo for intermediate storage through the discharge belt conveyor and bucket elevator. The wood chips are then made into qualified shavings by the ring flaker, and sent to the wet shavings bin by air.
Option II:
The wood raw materials are fed into the long-wood flaker by the feeding conveyor, and cut into qualified shavings at one time. And wind to the wet shavings silo.
third solution:
Small diameter wood and other long materials are fed into the long-product flaker by the feeding conveyor and cut into qualified shavings at one time. The shavings are blown to the wet planer bin. Short and small materials such as branches are sent to the feeding belt conveyor of the drum chipper. The qualified wood chips cut by the chipper are sent to the wood chip silo for intermediate storage through the wood chip wind. The wood chips are then made into qualified shavings by the ring flaker, and sent to the wet shavings bin by air.
2, drying and screening section
La salida de las ralladas del silo mojado se envía al secador del rotor vía el transportador de tornillo. Las astas secas se envían a la máquina de cribado por el transportador de tornillo para cribado. El transportador de tornillo de descarga del secador está equipado con un dispositivo de detección de chispas. Una vez que se emite una alarma, el material seco se puede descargar automáticamente del sistema. Las afeitadas gruesas tamizadas entran en la trituradora de nuevo para el reprocesamiento, y junto con el medio tamizado y las afeitadas gruesas, son enviadas al separador de flujo de aire por el transportador de tornillo para su clasificación. Los materiales finos calificados seleccionados son aire enviado al silo de partículas de superficie. Los materiales calificados seleccionados por el separador de aire son aire enviado al silo de las láminas de la capa de base para el almacenamiento intermedio. El material grueso clasificado entra en el molinillo para ser aplastado, y luego se fusiona con las finas astas que han sido tamizadas, y se sopla al silo de las astas superficiales. De acuerdo con las diferentes relaciones de las capas de superficie y núcleo cuando se producen diferentes grosores de tablero, parte de las capas de medio y grueso pueden transferirse cuantitativamente a la amoladora para hacer las capas de superficie.
3. Glue supply section
""Includes the preparation and delivery of paraffin emulsion and curing agent solution, the storage of additives and the preparation and application system of mixed glue. The surface and core layer mixed glue is configured in a centralized glue mixing machine. The preparation and application system of the mixed glue is controlled by PLC program. Automatic measurement, continuous configuration, quantitative application and adjustment are carried out according to the process regulations.
4, sizing section
The surface and core layer shavings are sized separately. The shavings are quantitatively output from the silo, pass through the vibrating discharger, and are continuously weighed by the metering device, and then enter the ring-type glue mixer in a balanced manner. The glue mixing machine fully mixes the incoming shavings and the atomized glue liquid, uniformly glues, and automatically adjusts the amount of glue according to the change of the shavings conveying volume to keep the glue ratio set by the process constant.
5. Forming hot pressing section
After sizing, the surface and core layer shavings are sent to the mobile air-flow laying machine by the belt conveyor. Two sets of opposite air-flow nozzles blow the shavings out, and form the upper and lower surfaces on the mesh belt of the forming conveyor to form a fine and uniform surface with a gradient Particle slab. The formed particle slab is cut into the required length by cross-saw, and the scrap is sent back to the paver through the air conveying system. After the single-layer hot press completes the hot pressing, the forming conveyor synchronously transports the rough board out of the press and the slab into the press. At the same time, the paving machine also moves rapidly in the same direction, and when it is in place, paving a new slab starts. Unqualified slabs can be sent back to the wet silo through the recycling device for reuse.
6, sawing section
The pressed rough board enters the board-out roller conveyor with a scale, centered and weighed. The centered and weighed rough board enters the vertical and horizontal edge sawing machine to saw the rough board into a straight edge board. Edged scraps can also be sent back to the wet bin. The edge-aligned plates are stacked by a roller conveyor through a stacking centering machine and a hydraulic lifting platform and then sent to the forklift roller table, and then sent to the intermediate storage by the forklift.
7, sanding section
The stored boards are then sent to the sanding system. The sanding system consists of a hydraulic lifting platform, a roller conveyor, a wide belt sander, etc. The sanded finished boards will be sent to the finished product warehouse after inspection and sorting.
8. Electronic control system
The particleboard production line is equipped with a main control room, from particle measurement, sizing, forming, hot pressing to edge weighing, and realizes automatic or manual operation according to the programmed PLC program. In addition, operating consoles (boxes) are set up at the operation site of each section (except the forming and hot pressing section) to control and monitor the operation of the equipment in this section.
