The application discloses a close-packed speed pursuit conveying mechanism and belongs to the technical field of conveying mechanisms. The mechanism comprises a primary adjustment mechanism for feeding and initially adjusting the interval of boxes, a conveying mechanism arranged on the primary adjustment mechanism for conveying the boxes, and a speed pursuit mechanism arranged on the conveying mechanism for adjusting the boxes into equal intervals. The primary adjustment mechanism is arranged to first comb and initially adjust the interval of the close-packed incoming boxes through limiting columns and material stirring distance setting, thereby laying a good foundation for subsequent fine adjustment. The speed pursuit mechanism adopts a unique chain plate type interval module. The boxes are accelerated through the friction drive of the speed pursuit rollers in the module until the boxes contact the front blocking plate and move synchronously with the module. Since multiple interval modules are fixed at equal intervals on the chain, the boxes conveyed by the interval modules are finally forced to be separated into completely equal intervals, which is more reliable than single adjustment mode.
