An arc groove 8 is arranged in the U-shaped groove 7, steel balls 9 are arranged in the arc groove 8, and the positions of the steel balls 9 are kept through a retainer 10, so that the positions of the steel balls 9 are unchanged but can freely rotate, and the rotating direction is not limited. Wherein the cage 10 is similar in construction to the cage 10 within a bearing. Two ends of the cloth roller 5 are placed in the U-shaped groove 7, and are contacted with the steel balls 9, so that the cloth roller rotates smoothly under the driving of external force. And the cloth roller 5 can be centered under the action of the arc electromagnet 12 and the annular permanent magnet 11. In the normal operation process, the arc electromagnet 12 generates magnetism, and the generated magnetism is opposite to the magnetism of the corresponding annular permanent magnet 11, so that the arc electromagnet 12 generates repulsive force to the annular permanent magnet 11, the arc electromagnets 12 at two ends apply thrust inwards to the cloth roller 5, the two thrust are kept consistent, and the cloth roller 5 is stable. When the cloth roller 5 approaches one of the ends, the pushing force of that end increases, causing it to move toward the other end.
