AI Technical Summary

Technical Problem

In the production process of steel-reinforced plastic composite pipes, the machine needs to be stopped and replaced when the weft yarn is used up, which leads to waste of raw materials and low production efficiency.

Method used

The main and auxiliary weft yarn reels are connected by a drive gear and a motor. A welding device is used to achieve synchronous rotation and welding of the main and auxiliary weft yarn reels. Combined with PLC control system monitoring and robotic arm operation, weft yarn changing can be achieved without stopping the machine.

Benefits of technology

This technology enables non-stop weft thread changing during the production of steel-reinforced plastic composite pipes, improving automation, reducing labor intensity, minimizing raw material waste, and increasing production efficiency.
