Forming machine for MDF/HDF production line

The dried fibers are transferred into the forming metering bin by the pneumatic system, and the paving rolls of the mechanic vacuum forming paves the fibers onto the circular conveyor. And the air will be sucked way by the mesh belts, under which there is vacuum case forming negative pressure, as while, the fibers are sucked on the mesh belt and form slabs gradually. In the next moment, the fluffy slabs will be compacted by the pre-press machine, and be sawed vertically and longitudinally to lengths required, and then the slabs will be transferred to the loader by the synchronous conveyor, speed-up conveyor, storing-board conveyor and extensible conveyor successively. After being loaded by the loader, the small machine in the loader will transfer the slabs together with the cantilever belt into the hot press machine. During this transferring process, the shovel at the front of the conveyor belt push the compacted slabs out, and the rough boards will enter the unloader as well as slabs get to the preset position when the small machine arrives at the termination. Then the small machine draws back as the belt revolve forward. The revolving speed of the belt is equal to the back speed of the small machine, so that the slabs are relatively static and stay on the hot press. The slabs will be formed to specified thickness under the temperature and pressure of the thermal compressor, and the inside glues will solidify.At last boards of certain strength will be made. Then the boards will be unloaded onto the carrier by the unloader, and unloaded and transferred to the next process by the discharge machine gradually when the suspension coop goes down layer by layer .

Advantage:

Use orientation plate structure design,make the OSB chips realize longitudinal and transverse directional forming ,to make sure the OSB mats after hot press section hae high station bending strength and plane tensile strength.
