The invention discloses a yarn bobbin mechanism for textile machinery, which comprises a base, fixed columns are fixedly connected to both sides of the top of the base, and a housing is fixedly connected to the top of the fixed column. The present invention is provided with a base, a fixed column, a shell, a pull ring, a movable rod, a first spring, a movable plate, a stabilizing mechanism, a limit plate, a connecting rod, a block, a bobbin body, a protective plate, a card slot, and a movable sleeve. , knobs, threaded rods, threaded holes, threaded grooves, fixed plates, grooves and supporting mechanisms are used in conjunction to solve the problem that the existing yarn bobbin mechanism for textile machinery is not easy to disassemble, requires a lot of manpower and material resources, and increases the labor intensity of workers , affects the use and use, and the protection effect is poor during the disassembly process, which may easily cause the bobbin to slip, cause damage to the textile, and cause inconvenience to the user. The advantage of good effect is worth promoting.
