[0018] The utility model in use, as Figure 1 、 4As shown, the door ring assembly 1 is circular, horizontally arranged and the central axis is arranged in the vertical direction, the upper door ring 11 and the lower door ring 12 serve as mounting brackets of the support pieces 13, a plurality of support pieces 13 are arranged uniformly along the circumference and form two tracks 3, a plurality of pairs of shuttle wheels 21 of the shuttle 2 are accommodated in the two tracks 3 at symmetrical positions respectively, so that the shuttle wheels 21 are supported radically and the positions in the up-down direction are limited, and when the shuttle 2 is driven to move in the circumference by an external power source such as a motor, the weaving work of the circular loom can be completed stably and orderly. The structure of the present scheme moves the structure position of the support and cooperation of the shuttle 2 and the door ring assembly 1 outward, which reduces the possibility of crushing the internal yarn. On the other hand, the shuttle wheel of the original structure is supported on the upper and lower door rings, if the positions of the upper and lower door rings cooperating with the shuttle wheel are worn or damaged, etc., which affects the normal operation of the shuttle 2, the door ring needs to be replaced, and the replacement cost and difficulty are relatively high, while in the structure of the present scheme, the upper and lower door rings no longer cooperate with the shuttle wheel, if the support piece 13 is worn or damaged, etc., the parts can be replaced individually, the cost and difficulty are greatly reduced, and the equipment downtime maintenance time is greatly reduced, so that the normal use of the equipment is ensured, and the weaving quality and efficiency are improved.
