Description

Technical Field

[0001] The utility model relates to the technical field of water jet loom equipment, in particular to a beating-up structure of a water jet loom. Background Art

[0002] The water jet loom is a shuttleless loom that uses a jet of water to pull the weft yarn through the shuttle. The frictional traction of the water jet weft insertion on the weft yarn is greater than that of the air jet weft insertion, and the diffusion is small, which meets the needs of weft insertion of filaments such as synthetic fibers and glass fibers with smooth surfaces. At the same time, it can increase the conductivity of synthetic fibers and effectively overcome static electricity in weaving. The existing water jet loom beating structure achieves beating by fixing the steel reed on the beating shaft and driving the beating shaft to rotate back and forth through a motor. The steel reed on the beating shaft is mostly fixed by fastening bolts and a pair of fixing rings. The steel reed fixed on the beating shaft may become loose after long-term use, and when adjusting the spacing of the steel reeds, the fastening bolts need to be loosened one by one, and then adjusted, which affects the use effect of the beating structure.

The two driving blocks can drive the resisting blocks to press each reed against the inner wall of the accommodating groove of the beating-up shaft to fix it. However, the threaded rod needs to be rotated to tighten the reed so that the threaded tube on the threaded rod moves from both ends to the middle. This process is time-consuming, and when a steel hoop is damaged, the damaged steel hoop cannot be replaced separately. When performing the beating-up operation, due to the offset of the center of gravity of the beating-up shaft, the stability of the rotation operation of the beating-up shaft will be affected, thereby causing the beating-up shaft to produce offset vibration, affecting its service life.
