Large Size Paper Cup Making Machine

The Jiuyi Large Size Paper Cup Making Machine is a continuous-motion, automated forming system engineered for high-volume production of large-capacity paper containers from 20 oz to 50 oz. Built on an annealed cast iron chassis with a precision-ground roller-gear indexer, this platform processes single and double PE-coated substrates (200–450 GSM) into rigid buckets and bowls. Independent servo-driven bottom paper feeding and dual-station thermal sealing eliminate bottom leakage and sidewall distortion under continuous 24/7 loads.

Mechanical Rigidity & Drive Precision
Annealed heavy-walled casting absorbs high-frequency shock, maintaining internal gear mesh tolerances within 0.02 mm during continuous high-load cycles.Heavy-duty cam indexers drive the 12-station turntable, ensuring precise positioning without mechanical backlash.
Thermal & Ultrasonic Sealing Architecture
Utilizes Swiss-imported Leister heating elements with closed-loop PID temperature regulation to stabilize longitudinal seam bonding on heavy double-PE stock. 20kHz digital ultrasonic generators provide instantaneous molecular bonding for bottom knurling and rim curling, preventing adhesive failure on thick stock.
Material Feeding & Waste Optimization
Rotary suction arms isolate and feed single blanks from the vertical magazine, preventing double-blank entry and mold damage.Independent servo motors control bottom disc blanking, reducing trim waste to below 3% through optimized nesting algorithms.

Engineered for industrial packaging converters supplying:
Cinema & Entertainment: Popcorn buckets (32 oz, 46 oz, 64 oz) requiring high compression rigidity and grease resistance.
Quick Service Restaurants (QSR): Extra-large fountain drink cups and bulk soup containers.
Convenience Foods: Instant noodle bowls and frozen dessert tubs requiring stable vertical stacking strength.

Tooling Interchangeability: Modular mold design allows complete size changeovers within 1.5 to 2 hours using standardized alignment dowels.
Electrical Architecture: PLC and HMI integration available via Siemens, Schneider, or Delta platforms.
Vision Inspection Integration: Optional inline camera systems detect bottom cracks, rim wrinkles, and side-seam voids, automatically ejecting defective units.
Auto-Lubrication System: Programmable centralized oil distribution connected to critical bearings and cam tracks to minimize manual maintenance.

Machining Standards
Primary frame structures and indexing turrets undergo CNC horizontal boring and milling in a temperature-controlled environment, holding dimensional tolerances within +/- 0.015 mm.
Component Traceability
Pneumatics & Electrics: Assembled using Schneider contactors, Omron proximity sensors, and SMC pneumatic cylinders.
Bearings: NSK and SKF high-load angular contact bearings installed on all primary drive shafts.
Factory Acceptance Testing (FAT)
Every unit undergoes a mandatory 72-hour continuous dry-run test followed by a 4-hour live production run using the customer's specified paper stock. Output samples undergo 24-hour dye penetration leak testing and sidewall crush resistance verification prior to crating.

Documentation Package: Complete electrical schematics, pneumatic flow diagrams, PLC ladder logic backups, and itemized spare parts manuals are provided in digital and hard-copy formats.
On-Site Support: Certified mechanical and electrical engineers are available for positioning, leveling, utility connection, and operator training.
Virtual Commissioning Option: For facilities with experienced in-house technicians, live-streamed technical guidance and pre-configured parameter templates support self-installation within 3 to 5 business days.

Spare Parts Inventory: Critical mechanical components, heating elements, and ultrasonic horns are maintained in stock for same-day dispatch via international couriers.
Remote Diagnostics: Integrated Ethernet ports allow engineering teams to securely access PLC parameters for real-time troubleshooting and program adjustments.
Warranty Coverage: 12-month standard warranty covering all non-consumable mechanical and electrical assemblies against manufacturing defects.
