The invention discloses a textile machine supporting device with a warning function. The textile machine supporting device comprises a bottom plate, supporting seats, damping rods, lifting rods and a top plate. The supporting seats are symmetrically arranged on the left side and the right side of the bottom plate. Sliding holes which allow the lower portions of the damping rods to slide are formed in the supporting seats. The upper portions of the damping rods are sleeved with the lifting rods. The top plate is fixedly installed at the top ends of the lifting rods. The lifting rod located on the left side is further provided with a rack. A motor seat is arranged between the supporting seats. A servo motor is fixedly installed on the motor seat. The servo motor drives a transmission wheel B to rotate. The transmission wheel B is connected with a transmission wheel A through a chain. The transmission wheel A is fixedly installed on a gear. The textile machine supporting device is simple and reasonable in structure, the height of textile machine equipment can be adjusted according to the working environment, and meanwhile, the warning function of vibration of the textile machine equipment is further achieved.
