Multilayer cache conveying line

At least two layers of conveying rollers are arranged on a bottom supporting frame, each layer of conveying rollers is arranged to be a plurality of conveying units, a driving shaft is arranged on thefront side of each layer of conveying rollers after the structural arrangement, and the driving shafts are arranged on the rear side of each layer of conveying rollers. Each driving shaft is providedwith a plurality of clutch devices to achieve control over a single conveying unit, through the structural arrangement, each conveying unit can be independently controlled under driving of the corresponding single driving device, and therefore buffering or conveying of various materials is achieved, and the conveying efficiency is improved. According to the multi-layer buffer conveying line, thesingle machine table is matched with multiple production lines for material supply, the line assembling cost is reduced, the material supply efficiency is improved, and the multi-layer buffer conveying line is ideal. 本实用新型公开了一种
