Single dryer three-channel dryer and single channel dryer, breakthrough the limitation of the rotor drier production, solve the bottle diameter of the biggest problems in particle board production

Use the advanced spray adhesive technology, make shavings sizing more evenly, rubber automatic proportioning according to different production requirements, according to the formula to complete automatic with glue (glue)

USES the advanced machinery, air surfacing technology, fine surface, higher precision (shop precision can reach within + / - 3.5%)C, on the basis of process test, the multilayer press hydraulic system scheme to optimize the performance of motor - pump, in order to get the reasonable configuration scheme, make the hydraulic system to achieve the optimal configuration

Fully considering the hanging plate post-processing section in time, also saw adopts high speed cutting, ensure the quality of the finished plate edge appearance

Electrical control adopts bus communication method, through the software process parameters to the process of production and operation status, fault condition, operation, monitoring and record set, a big increase in automatic closed loop regulating circuit, reduce manual intervention, to ensure the stable process operation.

　4、Introduction of technical process

Ordinary particieboard is used.usually wood, branch material, wood processing residues, non-wood crop residue as raw material, after shaving preparation, drying, the shop is forming hot-pressing section and made of a kind of man-made board.

　　1．Chip preparation section 

The flake board production line after shavings, screening the raw material to the wood transition storage bin. Wood of the conveyor to the flaking machine shaving preparation, after the preparation of the shavings by conveyor to the wet wood shavings bin in interim storage.

　　2．Drying section

Wet shaving the conveyor to the rotor type shavings dryer for drying, after drying of wood shavings by sorting (filter) qualified the core layer and dried by the conveyor was sent to the core layer shavings bin interim storage.Excessive shavings were taken to the surface after grinding machine grinding dry shavings bin interim storage.

　　3．Glue mixing section

Qualified table core layer dry wood wool after transport, shavings bin respectively metering to mix glue machine, also revised section will process required for JiaoGong adhesive solution to mix glue machine, shavings and adhesive liquid core layer in the table glue machine fully mixing, mixing fully sizing effect.

　　4．Forming section

After sizing of the shavings by belt conveyor to the mechanical classification shop is installed, by mechanical grading unit shop shop is a uniform flat slab.Slab by permanent magnetic iron remover, preloading machine, vertical sawing machine, sawing speed conveyor, cross-sectional, loading conveyor weighing conveyor, conveyor and storing process to hold the machine installed, such as hanging in a cage, the cage by the installed in the slab to multilayer hot-press hot pressing molding, after multilayer hot-press hot-pressing forming MAO board at the same time by the board the car tray to unloading machine.

　　5．After treatment section

Hair lay in the unloading machine plate after unloading conveyor sent to the cooling conveyor, by cooling into the conveyor to the cold machine for cooling.Stay cool in the machine (cooling) after MAO board by cooling conveyor to the vertical and horizontal cutting edge cutting machine for cutting edge segmentation, the last chance to lift platform by the dry plate transportation stacking.

　　6．Sanding section

The cooling of the stacking particleboard was sent to sanding production lines for sanding, sorting, warehousing.
