Shuttle track pair

Abstract

The invention discloses a shuttle track pair. The shuttle track pair comprises an upper door ring, a lower door ring, a shuttle, a plurality of stand columns which are uniformly arranged between the upper door ring and the lower door ring in the circumferential direction and have the cross sections being rectangular, a plurality of rolling wheels A on the upper door ring, rolling wheels B, rolling wheels C and rolling wheels D, the rolling wheels B, the rolling wheels C and the rolling wheels D are sequentially arranged on the stand columns, the shuttle is provided with a corresponding roller path A, a roller path B, a roller path C and a roller path D which cooperate with the rolling wheels A, the rolling wheels B, the rolling wheels C and the rolling wheels D respectively, and the rolling wheels A, the rolling wheels B, the rolling wheels C and the rolling wheels D are provided with protective covers. The shuttle track pair is characterized in that the axes of the rolling wheels A and the rolling wheels C are perpendicular and coplanar with those of the rolling wheels B and the rolling wheels D, the rolling wheels B are arranged at the upper ends of the rolling wheels C and the outer side of the shuttle, and the connecting positions of the stand columns and the upper door ring and the lower door ring and the mounting positions of the rolling wheels B and the rolling wheels D can be slightly adjusted. The shuttle track pair has the advantages that the width of the main force rolling wheels C can be greatly widened, a unit load is effectively lowered, the service life is prolonged, and the phenomenon that due to too high temperature rise, the efficacy is lost is avoided; the locating surface of the shuttle in the vertical direction is increased, and operation is more stable; all the rolling wheels are convenient to install, the precision requirement is easy to meet, and the rolling wheels C serving as interchangeable components are convenient to replace.

Description

technical field [0001] The invention relates to the field of plastic weaving machinery, in particular to a shuttle track pair of a plastic circular loom. Background technique [0002] At present, the shuttle track pairs of plastic circular looms used in the market all have the disadvantages of the warp being crushed by the shuttle wheel to varying degrees, resulting in scraping, warp breakage, and reduced weaving force. Among them, the most widely used tapered shuttle Especially for the track pair, the breaking force of the woven cloth dropped by 10% after testing, which affects the performance and cost of the woven bag, and the service life of the shuttle wheel in the track pair is only a few days, which brings inconvenience and cost to users. Increase and work efficiency improvement. [0003] The Chinese utility model patent "no shuttle wheel shuttle track pair" of notification number CN206204541U, though adopted the structure without shuttle wheel, has solved the warp th...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the problems of limited main roller wheel width, unsatisfactory positioning of the shuttle, and easy entanglement of warp threads in the existing shuttleless shuttle track pair, the present invention provides a shuttle track pair that can solve the above problems at the same time
