Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machine accessories, in particular to a limiting device for a warp knitting machine comb pull rod. Background Art

[0002] A knitted fabric is formed by using one or several groups of parallel arranged yarns to form loops on all the working needles of the warp feeding machine at the same time. This method is called warp knitting, the fabric is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine. The precise and reliable swinging of the warp knitting machine's guide bar is one of the important factors to ensure the accurate coordination of the warp knitting machine's looping movement.

[0003] In existing warp knitting machine equipment, it is often necessary to lift the comb bar on the cradle on site for maintenance, operation or replacement of the comb bar, which requires the comb bar to be removed from or installed on the equipment. During disassembly and assembly, the connecting rod of the comb bar is removed, and then the comb bar is removed from or installed on the cradle on the machine. In this process, the comb bar can be removed or installed from the cradle by loosening the pull rod nut and separating the lower pull rod from the upper pull rod. In this way, after the lower pull rod on the comb bar is separated from the upper pull rod, the lower pull rod and the lower rotating joint can rotate freely around the swing axis. When the equipment is started when the worker is not paying attention, the lower pull rod will swing left and right under the torque of the swing arm. During the swinging process, it may hit other accessories on the equipment or cause the angle position of the swing arm relative to the swing axis to change, and other accidents.

[0004] Based on the above background, a limiting device for a warp knitting machine bar pull rod is proposed to solve the problem raised. Utility Model Content
