AI Technical Summary
The existing air converter fails to cut the yarn in time when it breaks, causing the yarn to continue to be fed out, which affects the machine's operation and production efficiency.
A yarn cutting mechanism for an air converter was designed, including a yarn breakage detection device, a clamping device, and a cutting system. The sensor detects the yarn breakage and controls the clamping device to hold the yarn, while the cylinder drives the cutting system to cut off the broken yarn.
This technology enables timely cutting when yarn breaks, preventing further yarn feeding, ensuring normal machine operation, and improving production efficiency.
