Flexible supporting roller for winding disc

The invention discloses a flexible supporting roller for a winding disc. The flexible supporting roller comprises a bottom plate, supporting roller side plates, a supporting wheel and a supporting shaft. The bottom plate is arranged at the bottom. The two supporting roller side plates are symmetrically arranged at the front position and the rear position of the bottom plate. The supporting wheel is arranged between the two supporting roller side plates. The supporting shaft penetrates the supporting wheel to be fixedly arranged on the two supporting roller side plates. A self-aligning ball bearing is arranged in the supporting wheel and is fixedly connected with the supporting wheel. According to the flexible supporting roller for the winding disc, radial vibration generated in the process of automatically winding steel pipe antiseptic thermal shrinkage adhesive tape through the winding disc can be effectively adjusted and buffered, the stability of the winding disc is greatly improved, meanwhile, the rigidity of the winding disc is also improved, the influences of radial vibration of a steel pipe on the winding quality of winding the antiseptic thermal shrinkage adhesive tape are reduced, and the winding quality of the antiseptic thermal shrinkage adhesive tape is improved.
