The invention discloses an automatic loading system for extruded and cut-off rubber products. A material receiving device of the automatic loading system comprises a material receiving power roller set. A material delivering device of the automatic loading system comprises a material delivering power transmission belt set arranged beside the material receiving power roller set. A material turnover device of the automatic loading system comprises a turnover rack arranged between the material receiving power roller set and the material delivering power transmission belt set. A cantilever bar set is arranged on the turnover rack. A plurality of suction cups are arranged at the suspending-extending end of each cantilever bar. A material conveying device of the automatic loading system comprises a material conveying power roller set arranged at the output end of the material delivering power transmission belt set. A leaf truck conveying device of the automatic loading system comprises a leaf truck longitudinal traveling channel arranged beside the material conveying power roller set. A turnover manipulator of the automatic loading system is arranged at a loading station of a leaf truck. A material loading device of the automatic loading system is disposed on the other side of the material conveying power roller set and comprises a material supporting power transmission belt set distributed on a transverse and vertical movement mechanism. The automatic loading system avoids transverse and longitudinal pulling force on the products and also avoids twisting force, the dynamic balance and uniformity indexes of tires are changed, and the manpower cost is reduced.
