Description

Six-shuttle circular loom

Technical Field

The invention relates to the technical field of knitting equipment, in particular to a six-shuttle circular knitting machine.

Background

Before entering the circular loom, the warp is crossed and opened by the palm belt of the warp, and the weft shuttle moves circularly through the warp to form a tubular cloth.

The circular loom structure is generally composed of a frame, a host, a lifting mechanism, a guiding mechanism and a cloth rolling mechanism. The Chinese patent publication No. CN102094281A discloses a concave shuttle wheel and double-cone running track structure of a circular loom, and discloses a running mode of a shuttle body, wherein double cones are directly formed on an upper door ring and a lower door ring of a frame, then the concave shuttle wheel is arranged on a shuttle body, and the running on the upper door ring and the lower door ring is realized through the positioning of the concave shuttle wheel on the double cones.

When the equipment starts to make the shuttle body do circular motion, the shuttle body must generate a certain outward centrifugal force, so that the inner end of the shuttle wheel can generate larger pressure on the conical surface, the shuttle wheel can be worn after long-time working, the whole concave shuttle wheel can be loosened with the double conical surfaces of the upper door ring and the lower door ring, and even the problem of personal safety caused by the flying-out of the shuttle body occurs. The bidirectional positioning of the single female shuttle wheel ensures stable operation of the equipment by changing the single female shuttle wheel after the single side of the female shuttle wheel is worn.
