The invention discloses a rubber cutting sampling device and a rubber cutting sampling technology, which are used for cutting sample sheets from rubber sheets which are outputted by an open mill. The rubber cutting sampling device is characterized by comprising an upper roll, a lower roll and a die cutting tool, wherein the upper roll is correspondingly parallel with the lower roll, a gap is formed between the upper roll and the lower roll, each rubber sheet penetrates between the upper roll and the lower roll, and the die cutting tool is fixedly arranged on the circumferential surface of the lower roll; movable air cylinders are arranged at both ends of the lower roll, and are used for driving the lower roll to move towards or away from the rubber sheet; the rubber sheet outputted by the open mill is used for driving the upper roll and the lower roll to rotate, and the die cutting tool is used for cutting the sample sheet from the rubber sheet along with the rotation of the lower roll. The rubber cutting sampling device has the advantages and beneficial effects that the artificial cutting of the sample sheet is avoided, the cutting efficiency and flatness of the sample sheet are improved, the fatigue intensity of workers is decreased, and the waste of the material is avoided; the risk of scalding injury due to negligence of workers in the cutting and sampling process is decreased, and the safety in cutting of the sample sheet is improved at the same time.
