LLDPE film feeding slip
Problem Phenomenon
Unstable feeding and output fluctuation; pellets slip in the feed section.
Cause Analysis
LLDPE pellet shape and friction characteristics affect feed section conveying; excessive material temperature softens and sticks pellets, also causing slip.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solution
①Control feed section temperature; ②check pellet shape consistency; ③optimize feed section screw channel; ④stabilize feeding metering.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
Feeding stability is the premise of output stability; feed section temperature management is often overlooked.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
