when one screw rod rotates and drives the rod sleeve to move, the bearing is matched between the rod sleeve and the adjacent screw rod, the movement of the rod sleeve can drive the adjacent screw rod to move, so that the other screw rod moves, and meanwhile, the rotation of the other screw rod can drive the rod sleeve matched with the screw rod to move, so that the ring bodies between the adjacent rod sleeves can synchronously run for the same distance, the adjustment of the tightness of yarns passing through all the thread holes is ensured, and the production efficiency is further ensured;

of note are:

this embodiment can also control the pole socket of reason line board both sides through the control assembly and remove, promptly, motor control sprocket rotates to drive each sprocket through the chain and rotate, drive each gear rotation then, drive each rack by each gear and remove, and remove through each pole socket of rack control, promptly: the control rod seat is close to or far away from the wire arranging plate, and the purpose is as follows: when the rod seat is far away from the thread arranging plate, the contact position of the ring body and the yarn is changed, when the fine adjustment module runs in the state, the tightness of the yarn can be controlled from different positions, the yarn can be prevented from being damaged when the yarn is adjusted, the ring body is automatically controlled to move by the fine adjustment module, or the fine adjustment module is controlled by the control assembly to control the ring body to move, the yarn can be cleaned by the ring body, and the quality of the knitted socks is ensured; in addition, the control assembly of the embodiment can be used in the inclined state of the line arranging plate, and when the line arranging plate is in the inclined state, the close yarns are easy to knot, so that the control assembly controls the fine adjustment module to be away from and close to the line arranging plate, the yarns can be combed, the yarns can be prevented from being mutually wound and even knotted, and the production efficiency is further ensured;

it should be noted that:

the embodiment also provides a control system, the control system can be used for controlling the fine adjustment modules corresponding to the two sides of the plate body to synchronously operate or independently operate, when the fine adjustment modules on the two sides of the plate body synchronously operate, the adjustment stroke of the yarn can be rapidly increased, the mode is used when the yarn on the yarn barrel is separated at a high speed, and the phenomena that the yarns are contacted with each other due to rapid separation to generate knotting and the like are avoided;

in addition, when the fine adjustment modules on the two sides of the yarn arranging plate operate independently, the fine adjustment modules can slowly adjust the adjustment stroke of the yarns, so that the tightness of the yarns is slowly tightened.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
