The efficient fiber felt stacking and laying system comprises a supporting plate and a circulating unit, and the supporting plate is arranged below a feeding unit and used for bearing fiber felt; the feeding unit comprises a first conveying belt, and the first conveying belt is used for conveying the cut flaky fibrofelt to a supporting plate; the circulating unit comprises a rail assembly and a driving unit, the rail assembly supports the supporting plate upwards, and the driving unit can drive the supporting plate to move along a loop line of the rail assembly, so that the supporting plate receives the fibrofelt from the feeding unit for multiple times, and the fibrofelt stacking is completed; or the driving unit can drive the supporting plate to be separated from the rail assembly so as to transfer the supporting plate and the fiber felt to the next station. The fiber felt stacking and laying system is adopted in the fiber felt stacking and laying method. The device is reasonable in structure and convenient to operate, can adapt to continuous production, and is beneficial to improving the pore size distribution uniformity of stacked finished products.
