AI Technical Summary
Existing lithium battery conductive agent packaging machines have issues with conductive agent residue and clogging in their quantitative filling nozzles, which affect filling accuracy and increase maintenance costs.
The design combines a smooth coating with a vibration motor. The smooth coating reduces the adhesion between the conductive agent and the inner wall, while the vibration motor drives the filling nozzle to vibrate to ensure the conductive agent falls smoothly. The vibration process is stabilized by limiting and guiding structures.
Reduce conductive agent residue, prevent clogging, ensure filling accuracy, and reduce equipment maintenance costs and downtime.
