Supporting device of tubular strander roller

The utility model discloses a supporting device of a tubular strander roller comprising a roller, a rotating shaft, and a pedestal. After the improvement, the supporting device also comprises riding wheels sand a first leaf spring. Two ends of the roller are disposed on the rotating shaft in a supported manner, and the middle part of the roller is provided with a plurality of riding wheel groups having axes parallel to axis of the roller. Each of the riding wheel groups is provided with two riding wheels, which are respectively disposed on two sides of the roller wall. The first leaf spring is disposed under the roller, and the cross section of the first leaf spring is in the shape of an arc recessed towards the inner side. The middle part of the first leaf spring is fixedly disposed on the pedestal, and the central line of the first leaf spring and the axis of the roller are disposed in the same vertical plane. The two riding wheels of each group are fixedly disposed on the two ends of the first leaf spring by the own riding wheel supporting seats. The supporting device of the tubular strander roller is advantageous in that during the production of the tubular strander, the contact between the riding wheels and the roller can be well buffered, the rigid collision between the riding wheels and the roller can be relieved, and the mechanical noises can be reduced.
