LPX-138

Introduction of LPX-138 Open-Cam Mid-Speed Paper Cup Machine

1.Machine Structure: Built on a high-rigidity integrated cast-iron chassis measuring 2,170 × 1,150 × 1,820 mm with a net machine weight of approximately 2,100 kg (2.1 tons), the LPX-138 open cam paper cup machine occupies a compact factory footprint of only about 2.5 m² while maintaining a reliable forming tolerance within ±0.1 mm. Replacing conventional high-wear chain drives with a top-mounted open-cam architecture and high-precision spiral bevel gear transmission, this accessible automatic paper cup making machine ensures complete visual transparency for effortless lubrication monitoring and routine maintenance. Equipped with an energy-efficient 7 kW electrical system (5 kW heating capacity, with an actual running power consumption of around 5 kW/h) and a modest 0.3–0.5 MPa pneumatic requirement, it delivers dependable, whisper-quiet 24/7 continuous operation while significantly reducing electrical overhead and startup capital for emerging packaging plants.

2.Cup Production: In terms of manufacturing capabilities, this mid-speed paper cup making machine delivers a maximum mechanical speed of 138 pcs/min (recommended stable production at 100–130 pcs/min, monthly capacity around 3.95 million cups, scrap rate < 1.0%), flexibly accommodating an extensive cup size range from 2.5 oz to 16 oz and 140–350 gsm paperboards, including single and double PE-coated paper substrates. The optimized paper cup forming process integrates four-stage bottom pre-heating with heavy-duty toothed knurling embossing and dual-station progressive rim curling on the auxiliary plate, producing leak-proof, highly rigid coffee cups and beverage cups with smooth, uniform rolled rims that snap-fit tightly with standard disposable lids.

3.Inline Packaging: Engineered for modern labor-saving and hygienic manufacturing, the LPX-138 paper cup production machine features a pneumatic blow-out discharge channel and an automated optical counting collection table, allowing a single operator to oversee 3 to 5 machines simultaneously. Furthermore, it connects seamlessly via transfer conduits to the downstream LinpacX LPX-750 2-in-2-out automatic paper cup packaging machine, establishing a turnkey, automated paper cup production and packaging line from paper blank feeding to precise counting, stack collection, and trim-free film bagging. Synchronized with intelligent status monitoring, this untouched cup forming and packaging system effectively eliminates manual cup handling and secondary contamination, meeting strict food-grade packaging standards while drastically reducing operational labor costs.
