Description

Technical Field

[0001] The utility model relates to a six-link beating-up mechanism for a water jet loom, belonging to the technical field of beating-up of a water jet loom. Background Art

[0002] The frictional traction of water jet weft insertion on the weft yarn is greater than that of air jet weft insertion, and the diffusion is small, which is suitable for the weft insertion of smooth-surface synthetic fibers, glass fibers and other filaments. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving; in addition, jet weft consumes less energy and has the lowest noise.

[0003] In the prior art, for example, the Chinese patent number CN 117051526 A discloses a six-link beating mechanism, which includes a crankshaft connecting rod, a bearing connecting rod, a triangular connecting rod, a small eight-shaped connecting rod, a rocker, a swing shaft and a reed. One end of the bearing connecting rod is rotatably connected to the connecting rod journal of the crankshaft connecting rod, and the other end of the bearing connecting rod is rotatably connected to the lower corner end of the triangular connecting rod. The triangular connecting rod is mounted on a frame through a central axis. The upper corner end of the triangular connecting rod is rotatably connected to the small eight-shaped connecting rod, and the other end of the small eight-shaped connecting rod is rotatably connected to the lower end of the rocker. The upper end of the rocker is axially connected to the central rotating shaft of the swing shaft, and the flange end of the swing shaft is connected and mounted with the reed. The beneficial effects are that the overall structure is simple, the shock resistance is good, the beating force is significantly improved, and the rear pause time of the steel reed is long, which increases the weft introduction angle, and the weft yarn passes more smoothly and stably. It can not only weave low-weight fabrics, but also is suitable for weaving high-weight fabrics; at the same time, it can also reduce the vibration and noise of the beating part of the loom.

[0004] However, in the prior art, when using a six-link water jet loom to beat the weft, the rotation speed of the wide loom can be increased, and the center of gravity of the beating mechanism is far away from its swing axis (the rotation axis of the beating shaft), so that the beating mechanism produces more serious irregular vibrations during operation, affecting the beating accuracy, product quality and production efficiency.
