Thread breaking stopping device of plastic circular weaving machine

Abstract

The invention relates to a thread breaking stopping device of a plastic circular weaving machine. The device comprises multiple archways distributed at intervals in the circumferential direction, jumping bars, jumping bar support rods, springs and spring support rods are arranged between the adjacent archways, the jumping bars sleeve the jumping bar support rods, one ends of the springs are connected with the lower ends of the jumping rods, the other ends of the springs are connected with the spring support rods, annular insulation support rods are arranged at the outer ends of the jumping bars, and multiple sections of conducting films used for making contact with the jumping bars when warp is broken are arranged on the insulation support rods in the circumferential direction. According to the technical scheme, the thread breaking stopping device of the plastic circular weaving machine is provided, the machine can be stopped rapidly when the jumping bars make contact with the conducing films, the conducting films are arranged in areas, and warp in which area is broken can be judged rapidly; the sensitivity of the conducting films is good, and the rapid stopping stability is good.

Description

technical field [0001] The invention relates to the field of plastic circular looms, in particular to a thread break stop device for plastic circular looms. Background technique [0002] The Chinese invention patent No. 201120034868.5 discloses a plastic circular loom automatic stop device for broken warp yarns, including arches, jumpers, jumper poles, springs, spring poles, jumper spacers, and outer spacers. The rod, the inner rod of the spacer, the jumper pole, the spring pole, the outer pole of the spacer and the inner pole of the spacer are all arranged in one piece on the circumference, and the outer end of the jumper is provided with a conductive tube arranged in a circle, and the insulating ring encloses the conductive tube to It is fixed on the archway, the jumper is looped on the jumper pole, the jumper spacer is stuck on the outer pole of the spacer and the inner pole of the spacer, the upper end of the spring is connected with the lower end of the jumper, and the ...

AI Technical Summary

Problems solved by technology

However, the shutdown device of this structure has the following defects: (1) the stroke between the jumper and the conductive tube is large, resulting in a long shutdown time when the warp is broken; (2) because the conductive tube is integrally arranged around the circumference, it cannot Partition management is formed, that is, when the wire is broken, it is impossible to directly determine which area the warp wire is broken, and workers need to search one by one, which is inefficient; (3) the sensitivity of the conductive rod is low, and sometimes it is impossible to stop the machine; (4) due to the jumping rod support Rods, spring poles, spacer outer bars and spacer inner bars are all arranged in one piece around the circumference. When installing, it is necessary to cover all the jumping bars, jumping bar partitions, and archways one by one, which is inconvenient to install. , when a part of a part is damaged and needs to be repaired and replaced, it needs to be removed as a whole, which is inconvenient for maintenance
