Product Overview
The Standard Single PE Paper Cup Forming Machine is designed for continuous and stable production of single-side PE coated paper cups used in hot and cold beverage packaging industries.
The machine is engineered around production stability, forming precision, and long-cycle operational consistency rather than short-term speed performance. It integrates synchronized mechanical transmission, ultrasonic sealing, and controlled bottom forming into a unified production system to ensure consistent cup geometry during long-hour operation.
For manufacturers where production continuity directly impacts delivery schedules and operating cost control, this model provides a stable and predictable forming solution for industrial-scale paper cup production.
Core Engineering Advantages
Heavy-Duty Mechanical Drive System: Replaces traditional chain drives with high-tensile gear mechanisms and a vertical shaft transmission. This design ensures precise synchronization across all stations, mitigating mechanical deviations during continuous long-term operations.
Advanced Barrel Group Indexing: Features an optimized cylindrical indexing cam that guarantees smooth transition intervals between multi-station processes, maintaining positioning accuracy under sustained maximum speeds.
Precision Sealing Technology: The side-seam sealing utilizes a specialized heater module that applies uniform thermal energy to the single PE film, creating an airtight, leak-proof bond without degrading the structural integrity of the paper fibers.
Bottom Knurling Consistency: Equipped with a mechanical bottom-feeding unit that cuts and places bottom discs with zero overlap error. The heavy-pressure knurling wheel guarantees precise pattern definition to eliminate bottom leakage risks.

Machine Structure & Operating Sequence
The machine architecture consists of three synchronized operational zones:
Feeding & Pre-Heating: Pre-cut single PE paper blanks are automatically picked via vacuum suction cups and aligned into the side-seam welding station.
Sleeve Forming & Bottom Insertion: Welded paper sleeves transfer onto main forming mandrels where the bottom paper strip is automatically blanked from the roll and inserted.
Heating, Knurling & Curling: The bottom is pre-heated and knurled to activate the PE layer for an absolute seal, while the top rim undergoes mechanical lubrication and top-curling to ensure rigid cup lips.
Pneumatic Collection: Finished cups discharge into the collection chute, monitored by an integrated photo-electric tracking counter for seamless stacking.

Frequently Asked Questions
Q: What raw materials are required to run this machine efficiently?
A: The system operates optimally with 150 to 350 GSM single PE coated paper blanks. To maintain stable 90 pcs/min speeds, the flatness and die-cutting precision of the paper blanks must meet standard industrial tolerances.
Q: How is the cup size changeover process managed?
A: A full mold changeover is completed within 4 to 8 hours by a trained technician. It requires replacing the corresponding mold components, including forming mandrels, bottom heaters, and curling dies, to adapt to the new dimensions.
Q: How does the machine ensure leak-proof bottoms in single PE paper cups?
A: Leakage prevention is achieved through a multi-stage heating process combined with a heavy-duty knurling matrix. This system applies uniform pressure and calibrated thermal energy to fully activate the single PE layer, fusing it into a permanent, watertight joint.
Q: What is the maintenance cycle for the drive systems?
A: The internal main gears and index cams require a lubricating oil change every 2,000 operational hours. Operators monitor oil levels weekly via the automatic lubrication system to keep the mechanical drive train running smoothly.
