Features of Technological Deisgn on Blockboard Production
Taking a blockboard production line with capacity 10 000 m 3/a as an example, this paper described features of technological design and equipment selection. In accordance with different lumber quality, two distinct planning techniques. were selected, i.e.two face planning machine was selected for planning straight lumber and planning machine befoe thickening machine was selected for planning warped lumber. A finger jointer was selected and finger jointed strips were used in two sides of blockboard core. These measures could improve the strength of blockboard as well as appearance quality. The glued blockboard core was planned through a wide thickening machine. Gas was used for heat conduction medium of dry kilns, reducing energy consumption by 40%. Thermal conductive oil was used as heat conduction medium of blockboard core composing machine and hot press, reducing energy consumption by 30%. A pulse bag type collector was selected to improve collection effectiveness of sanding dust.
