LLDPE film auxiliary equipment matching
Problem Phenomenon
The main machine is normal but the auxiliary equipment state drags down overall quality.
Cause Analysis
The state of the air ring, bubble stabilizing frame, haul-off, winder and other auxiliary equipment directly affects film quality; auxiliary equipment maintenance is often overlooked.; During on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience.
Solution
①Establish an auxiliary equipment inspection system; ②calibrate haul-off and winding; ③maintain the air ring and bubble stabilizing frame; ④train auxiliary equipment maintenance.; After adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability.
Key Takeaway
Film quality is the result of whole-line coordination; auxiliary equipment management must be valued equally with the main machine.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.
