The invention discloses a roller pressing system special for Eucommia ulmoides bark. The roller pressing system comprises a rack. Two pairs of pressing rollers are arranged on the rack. The pressing rollers in each pair are horizontally parallel to each other and are vertically arranged. The roller pressing center planes of the two pairs of pressing rollers coincide with each other. A supporting roller shaft is arranged between the two pairs of pressing rollers. Roller sleeves are embedded to the outer circumferences of pressing roller bodies of the two pairs of pressing rollers respectively. Circumferential-direction rectangular protrusions are arranged on the outer circumferences of the two roller sleeves I of the first pair of pressing rollers, and triangular-pyramid-shaped protrusions are arranged at the top ends of the rectangular protrusions. Axial rectangular protrusions are arranged on the outer circumferences of the two roller sleeves II of the second pair of pressing rollers, and the cross section of the axial protrusions are jagged. The jagged opening direction is the same as the rotating direction of the pressing rollers. According to the roller pressing system special for the Eucommia ulmoides bark, roller pressing is carried out on Eucommia ulmoides bark, and meanwhile a wood layer covering a gum layer is pierced, cut off and damaged, so that the non-gum wood layer is sufficiently fragmented, the original physical state and physical performance of the eucommia ulmoides gum are ensured, and a foundation is laid for the integrity and higher gum obtaining rate of the eucommia ulmoides gum.
