[0002] The sinker holder in a lingerie knitting machine is used to support and secure the sinker, a crucial component in knitting machines that controls the formation and movement of loops during knitting. Sinkers, typically made of thin steel sheets, are arranged alternately with the needles to hold the loops during knitting, assisting the needles in forming the loops.

[0003] The design of the sinker seat needs to take into account the dynamic characteristics of the knitting machine and the movement trajectory of the sinker. In order to facilitate the adjustment according to different knitting requirements and fabric characteristics, it is necessary to ensure that the sinker seat has a certain degree of adjustability. However, most existing sinker seats adopt a fixed installation method, which cannot be adjusted and positioned in time for different sinkers, which is not conducive to accurate knitting of different fabrics.

[0004] Therefore, in view of the above-mentioned problems, the present technical solution proposes a sinker seat mechanism for an underwear machine. Utility Model Content

The sinker ring refers to the annular path formed by the sinker inside the needle cylinder. The sinker moves on this path to assist in the formation and release of the coil. During the knitting process, the above components work together to achieve efficient and high-quality knitting production through precise mechanical movements and electronic control; one side of the bottom of the sinker seat is plug-in and positioned with the sinker. The sinker seat includes an L-shaped rod and a positioning block detachably installed at the bottom of the L-shaped rod end. The positioning block is positioned and connected to the slot on the sinker. The plug-in connection between the positioning block and the L-shaped rod is convenient for selecting the appropriate positioning block according to the different shapes of the slots on the sinker for accurate positioning.

[0007] Compared with the prior art, the beneficial effect of the present invention is that by detachably connecting the positioning block and the sinker seat, it is convenient to select a suitable positioning block and sinker for accurate positioning and support according to the shape of the sinker, thereby improving the adjustment ability of the sinker seat, thereby increasing the variability of the sinker and expanding the scope of application of the underwear machine.
