Plastic circular weaving machine

Abstract

The invention relates to a plastic circular weaving machine. The plastic circular weaving machine comprises shuttles, a slope runway and fastening doors, each shuttle comprises a shuttle body, an upper shuttle wheel and a lower shuttle wheel, the slope runway includes an upper runway and a lower runway, shuttle body permanent magnets are uniformly arranged at the bottom of each shuttle body, door fastening permanent magnets are uniformly arranged in the middle of each fastening door, the shuttle body permanent magnets and the corresponding door fastening permanent magnets are opposite to one another and are the same in polarities of opposite surfaces, slopes of the upper runway and the lower runway are provided with limiting bosses, and axles of the upper shuttle wheels or the lower shuttle wheels are eccentric axles. The plastic circular weaving machine has the advantages that higher repelling force generated among the shuttle body permanent magnets and the door fastening permanent magnets is used for counteracting one part of centrifugal force of the shuttles, so that pressure borne by organzine among the shuttle wheels and the upper runway as well as among the shuttle wheels and the lower runway is decreased, and yarn splitting, fuzzing and yarn breakage are reduced; the plastic circular weaving machine is lower in strength requirements on yarns and suitable for knitting of various high-strength and low-strength yarns; and the service lives of the shuttle wheels are also prolonged.

Description

Technical field [0001] The invention relates to the manufacturing field of plastic circular looms, in particular to a plastic circular loom. Background technique [0002] During the weaving process of the plastic circular loom, the shuttle keeps moving in a circular motion. figure 1 Shown is a schematic diagram of an existing plastic circular loom shuttle and its running track. The existing shuttle has four shuttle wheels 22, two of which are matched with the upper track 21, and the other two are matched with the lower track 26. When the warp thread 23 passes through the slopes of the upper and lower tracks 21 and 26, Rolling of wheel 22. The circular loom of this structure has the following disadvantages: [0003] 1. Since the centrifugal force is proportional to the square of the speed, the centrifugal force will increase sharply as the speed increases. The shuttle runs at high speed, which produces a large centrifugal force, and the pressure of the shuttle wheel on the slope ...

AI Technical Summary

Problems solved by technology

The high-speed operation of the shuttle produces a large centrifugal force, and the pressure of the shuttle wheel on the slope of the runway is also relatively large, which makes the shuttle wheel easy to wear and tear. Generally, the replacement cycle of the shuttle wheel is only ten days, and the maintenance cost is high.

[0004] 2. When the warp passes through the matching surface between the shuttle wheel and the upper and lower tracks, because the pressure of the shuttle wheel on the warp is also relatively large, it is easy to cause splitting, fluffing, and broken threads, which will affect the quality of weaving products.
