The invention belongs to the field of cement bag conveying and particularly relates to an intelligent truck loading system for cement bags. The intelligent truck loading system comprises a dischargingconveying belt, a cement bag direction adjusting device, a discharging deceleration conveying belt, a discharging truck loading conveying belt sliding rail, a discharging truck loading conveying belt, a material splitting stacking device and a lifting and transverse-moving driving device. By means of the intelligent truck loading system for the cement bags, the cement bags can be stacked and stored at any position in a truck carriage, the manual carrying cost is reduced, the truck loading efficiency is improved, in addition, automatic equipment is adopted for intelligent operation in the whole carrying process of the cement bags, splashing of cement ash is reduced, manual carrying is not needed, and the body health of workers is effectively guaranteed. The invention further provides an intelligent truck loading method for the cement bags, the intelligent truck loading system for the cement bags is adopted in the intelligent truck loading method for the cement bags. Intelligent carrying of the cement bags is achieved, and the problems that in the prior art, during manual carrying and truck loading of the cement bags, the efficiency is low, the truck loading cost is high and the labor intensity is high are solved.
