Fully Automatic 100~700 Cbm Per Day Particle Board Multi Opening Press Production Line
Description
The panel to be processed, laid up on an additional working station, is placed over the loading belt that moves inside the press once the panel has reached a referring position. During the return step, the loading belt rotates contrary wise to the transfer movement at the same linear speed leaving the panel inside the press daylight. The daylight is closed and get in pressure by closing the movable platen and the underlying one that is blocked and make it integral, in the meantime the structure moves vertically in order to align the second working daylight to the loading belt. The movable platen opens along with the underlying one and the second working daylight opens. The loading, the closing and the getting in pressure are the same as the above described for the first working daylight. When the working daylights loading sequence, for the all is over, the structure moves vertically and comes back to the first daylight where the first loaded panel is laying for the whole working cycle. Now the glue has dried up and the panel is ready to be unloaded. With the new loading cycle, the loader, during its transfer inside the press, unloads the processed panel by pushing and moving it over the unloading roller device that starts moving as soon as the panel is detected.
The 110~500 cbm/day PB production line has automatic operation system, reasonable technical process, stable running. It can produce 4 x 8, 6 x 8, 6 x 9,6 x12 sized PB. This production line uses the waste of wood process factory and branches of wood as raw material, after chipping, flaking, drying, sifting, hot-press, sanding and cutting to produce particle board. The particle board can be used for furniture, building construction, package, inner decoration of vehicle and ship, and short-cycle over-laying particle board for decoration.

Main characteristics of particle board production line
- Good adaptation of raw material: Small wood-log, branches, residue of the wood processing, can be used as raw material for particle board.
- Lower glue consumption: The electrical measuring and adjusting of the ratio between various materials and glue, the proportion between the flakes and the glue can be controlled by computer system on line. High pressure glue injection, can ensure the glue mist very well, which is good for glue blending and lower the glue applying consumption.
- Homogeneous structure of mat: The forming machine adopts the advanced mechanical classic-forming, with special diamond roller, to ensure ideal spreading, improve the board quality in the end.
- Hot-pressing system: Adopting multi-opening press, ensure the press closing synchronal by both mechanical and hydraulic methods. The board thickness tolerance is less, in order to reduce sanding amount.
- High efficiency automatic control: The whole electrical control system of the production line adopts world advanced electrical elements, the control system work reliably and stably.
