Description

Technical Field

[0001] This utility model relates to the field of track link production technology, specifically a track link flaw detection fluid blowing device. Background Technology

[0002] Track links are a crucial component in construction machinery, especially tracked machinery (such as excavators and bulldozers). They are the basic unit of the track system, responsible for connecting and supporting the tracks to provide stable movement on various terrains. Currently, in the manufacturing process of existing mechanical track links, a flaw detection fluid is sprayed onto the surface. After flaw detection, the fluid adsorbed on the track link surface needs to be blown off to facilitate subsequent processing. However, existing track links often use a fixed structure for this process, preventing sufficient blowing. Furthermore, the air source is often fixed, hindering the modification of airflow trajectory and reducing the efficiency and quality of fluid removal.
