Stereoscopic equipment used for producing fiber web used for non-woven fabric

The invention relates to stereoscopic equipment used for producing a fiber web used for non-woven fabric. The stereoscopic equipment comprises at least two carding machines installed at front and backstaggered positions in an upper frame and combined to form a fiber web, and at least two carding machines installed at front and back staggered positions in a lower frame and combined to form a fiberweb; the rear part of the carding machine I located at the front part of the upper frame is provided with an upper transport component driven by a separate power mechanism and extending backwards; the rear part of the carding machine III located at the front part of the lower frame is equipped with a lower transport component driven by a separate power mechanism and extending backwards; a 1# fiber web output from the carding machine I installed in the upper frame moves forward along the upper transport component, and is merged with a 2# fiber web output from carding machine II in the width direction when passing the r
