LDPE Regrind Fluffy Material
Fenómeno del problema
After blending recycled fluffy material, output and film thickness fluctuate unpredictably
Análisis de la causa
Fluffy regrind has low and unstable bulk density; the screw feeding section conveys only volume and does not weigh, so when there is more fluffy material the actual feed decreases, and output and film thickness decrease synchronously; when troubleshooting on site, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solución
① Use a proportional feeder to blend regrind quantitatively; ② add a compaction device to the hopper; ③ equip a forced feeding system for large amounts of regrind; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Conclusión clave
The key point of fluffy regrind is uncontrolled bulk density; proportional feeding plus compaction turns volume conveying into controlled feeding; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
