如何延長吹膜機的使用壽命？

Walk around the whole machine to check loose bolts, oil leakage, worn belts and damaged hoses. Ensure all safety protective covers are installed in place. This simple inspection can discover hidden risks in advance during production.

使用軟銅刷清除模口唇緣上的樹脂殘留物，並擦拭乾淨氣環內部通道。殘留物會導致膜厚不均勻和氣泡不穩定。清潔的氣環可確保均勻冷卻和穩定的氣泡形成。

Test the working state of each heating band and view real-time temperature data on the control system. If any heating zone keeps cold or overheats, stop production for troubleshooting. Uneven heating will produce gel fisheyes on the film surface.

每批生產結束後，用清潔劑清除殘留塑膠。觀察壓力表讀數和電機電流；數據突然波動表明內部堵塞，這將污染後續的薄膜產品。

Check control cabinet and terminal boxes for loose wires or overheating traces, and fasten all loose wiring timely. The control system relies on stable power supply to realize precise parameter control.

打開冷卻風扇，待機器溫度完全下降後再關機。徹底清潔模具、螺桿和氣環，以防止塑膠碳化。

1Add the recommended lubricating oil to gears, bearings and chains. Do not over-lubricate, otherwise excess oil will absorb dust. For most blown film equipment, No.6 engine oil needs to be added every two working days.

觀察螺桿表面是否有刮痕和凹坑，並檢查筒體內壁的平滑度。磨損的螺桿會導致塑膠熔化不穩定，並改變成品薄膜的物理性能。

Tighten loose connectors of heating bands. Loose joints cause local overheating and generate film fisheyes.

清除料斗和進料螺旋輸送器中積聚的灰塵和塑膠碎屑，以確保原料穩定輸送和薄膜厚度均勻。

Test belt tension: loose belts will slip and reduce driving power, while over-tight belts will damage bearings. Adjust the tensioner as required and lubricate chains sufficiently to ensure smooth line operation.

清潔出風口和內部風道。用手感受氣泡周圍的氣流，判斷其均勻性。冷卻不均勻會導致氣泡晃動和厚度偏差。風環的品質決定了生產線的整體冷卻性能。

Compare thermocouple readings with standard measuring tools and calibrate if the error exceeds ±2°C. Accurate sensors realize stable plastic melting and extrusion, supporting precise control of the whole production process.

拆卸換網器並檢查濾網。及時更換堵塞或損壞的濾網。堵塞的濾網會阻礙塑膠流動並降低薄膜質量，而乾淨的濾網可以避免吹膜擠出生產線的原料受到污染。

Check die wear and assembly offset, test the operation of each heating ring, and fasten all loose bolts to prevent melt leakage and uneven plastic distribution. Proper die maintenance can keep stable physical performance of film.

用壓縮空氣吹掉電路板和電子元件上的灰塵。灰塵堆積會導致設備過熱和間歇性電路故障。

Check whether there are metal debris or water mixed in the gear oil. Replace contaminated oil immediately. Insufficient or dirty oil will greatly shorten the service life of the gearbox.
