Description

Technical Field

[0001] This utility model relates to the field of plastic circular loom technology, and in particular to a shuttle and a plastic circular loom. Background Technology

[0002] In the field of plastic circular looms, the shuttle, as a core moving component, directly affects weaving efficiency and fabric quality due to the reliability of its outer guide rod. In traditional shuttle structures, the two ends of the outer guide rod are fixed to the front and rear ends of the shuttle body, respectively. However, under high-speed reciprocating motion, the following inherent defects exist: the rear end of the outer guide rod is only fixed by a flat surface or a simple screw, which easily generates lateral micro-vibration under the alternating action of centrifugal force and yarn tension.
