AI Technical Summary

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

The utility model relates to the technical field of fishing net production, and particularly relates to a fishing net machine hole plate up and down movement subassembly, sets up the rotation lever to drive the hole plate up and down movement through the movement gear and rack, and the rotation lever is driven by the movement motor, and the movement motor is equipped with two and is located two ends of the rotation lever respectively, two movement motors reverse directions are opposite, are respectively used for driving the rotation lever normal rotation and reverse rotation. Through two ordinary movement motors can play the role of servo motor, can adjust the track and will not appear the track deviation problem of abrasion. At the same time, compared with servo motor system, the cost is lower, and the requirement to the environment is also not high. The intermitting mechanism is arranged between the movement motor and the rotation lever, can control the connection or disconnection between the movement motor output shaft and the rotation lever. Therefore when one of the movement motors works, the working movement motor can be connected with the rotation lever, and the other stopped movement motor will be automatically disconnected with the rotation lever.
