Reed door type shuttle rail pair

Abstract

The invention relates to a plastic knitting machine and discloses a reed door type shuttle rail pair. The reed door type shuttle rail pair is characterized by comprising a reed door rail, an internal horizontal rail and a shuttle, the reed door rail comprises sheet inner side faces arranged between an upper door ring and a lower door ring and an inner side face of a stand column, the internal horizontal rail comprises the stand column and wheels arranged on the stand column, the shuttle comprises a shuttle body, shuttle wheels and seam allowances, the shuttle wheels are matched with the reed door rail in a rolling mode, the seam allowances are matched with the internal horizontal rail in a rolling mode, the wheels are paired in an up-and-down mode, the wheels are fixedly connected to the stand column, the outer diameter of the wheels is smaller than the width of the stand column, and warps penetrate through the part among the upper door ring, the lower door ring and the shuttle body. The reed door type shuttle rail pair has the advantages that the shuttle is suspended in the intersection of the warps all the time in the work process, the shuttle does not grind the warps, the faults of yarn scraping, yarn breading and the like caused by shuttle wheel grinding are thoroughly overcome, the knitting reliability is greatly improved, and the requirement for the strength of flat yarns of a knitting machine is lowered.

Description

technical field [0001] The invention relates to a plastic weaving machine, in particular to a reed door type shuttle track pair of a plastic circular loom. Background technique [0002] When the plastic circular loom is working, the shuttle moves in a circle to complete the weft threading action. In addition to the radial constraint (ie, the horizontal direction), it must also have an axial (ie, vertical) constraint. In the prior art, no matter the reed door The track pair, the roller track pair, and the tapered track pair all use an external horizontal track pair for axial restraint, that is, a track pair composed of a shuttle wheel and a door ring. The disadvantage of this structure is that when the shuttle is working, the warp wire When passing through the gap between the door ring and the shuttle, the shuttle wheel will crush the warp, which may easily cause faults such as scraping and broken warp, which will affect the normal operation and reliability of the loom, and h...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to provide a track pair for a plastic circular loom, which can effectively solve the problems of scraping and broken warp caused by the existing shuttle rolling the warp, improve the reliability of the loom, and reduce the requirements for the strength of the warp
