[0002] Warp knitting machine, as an important equipment in the field of textile engineering, is mainly used to produce warp knitted fabrics. Warp knitted fabrics are knitted fabrics formed by one or several groups of parallel yarns, which are looped simultaneously on all the working needles of the machine fed in the warp direction. Warp knitting machines are mainly composed of five parts: weaving mechanism, bar slidable mechanism, warp feeding mechanism, pulling and winding mechanism and transmission mechanism.

[0003] Warp knitting machines are subject to mechanical vibrations during their high-speed, high-load operation, which not only affect the machine's operational stability and production efficiency, but may also damage the equipment itself.

[0004] Therefore, in the prior art, a vibration isolation pad or a vibration isolator is installed at the bottom of the warp knitting machine to isolate the equipment from the ground or the supporting structure, reduce the transmission of vibration to the basic structure, and thus reduce the impact of vibration on the equipment. In the prior art, there is a vibration absorber, which includes a mounting base, a connecting piece, a spring and a rubber element. The spring and the rubber element are arranged in the mounting base and connected to the connecting piece; the connecting piece passes through the bottom of the warp knitting machine and is connected to a fixing nut.

[0005] With regard to the above-mentioned related technologies, since the existing technologies have a service life, the rubber elements and springs will wear out or age after long-term use. When the existing technologies need to be replaced, the warp knitting machine needs to be lifted and reinstalled, which is inefficient and troublesome. Summary of the invention
