A net machine hole plate up and down movement assembly
By using two opposing motion motors to drive the rotating rod in the fishing net machine, combined with a gear rack and pinion mechanism and a connecting mechanism, the problems of cam mechanism wear and high cost of servo motors are solved, achieving high-precision perforated plate movement and a low-cost solution.

AI Technical Summary
In existing technologies, conventional cam mechanisms that drive the up-and-down movement of the perforated plate cannot be adjusted and are prone to wear, resulting in a decrease in the accuracy of warp winding. In contrast, direct drive servo motors are costly and have strict environmental requirements.
Two opposing motion motors drive the rotating rod, and the orifice plate moves up and down through the meshing of the motion gear and rack. A connecting and disconnecting mechanism controls the connection or disconnection of the motor and the rotating rod. The trajectory is adjusted by using a sliding electric ring and an electromagnet, which reduces costs and avoids wear.
It enables flexible adjustment of the trajectory, avoids trajectory deviation caused by wear, reduces costs, reduces environmental requirements, and improves the accuracy of meridian loop formation.
