The invention relates to the technical field of textile machines and discloses a buffering device for a textile machine. The buffering device comprises a supporting cylinder body. A supporting shaft is arranged in the supporting cylinder body, and a roller is coaxially and rotationally connected to the outer surface of the supporting shaft. A barrier plate is arranged on the inner wall of the lower end of the supporting cylinder body. The end of the barrier plate is slidably connected to the outer surface of a drum. A first pressing plate and a second pressing plate are arranged on the outer surface of the roller. The ends of the first pressing plate and the second pressing plate are both slidably connected to the inner wall of the supporting cylinder body. A first compression cavity is formed between the first pressing plate and the barrier plate, and a second compression cavity is formed between the second pressing plate and the barrier plate. A supporting rod is hinged to the position, corresponding to the end of the barrier plate, of the outer surface of the roller, and a fixing block is hinged to the end, away from the roller, of the supporting rod. The vibration of the textile machine is converted into the power to drive the supporting rod to move and compress hydraulic oil in the supporting cylinder body by the first pressing plate or the second pressing plate, so that the purposes of shock absorption and noise elimination of the textile machine are realized.
