Core Selling Points of Intelligent Paper Cup Machine

upload/1c/202507/intelligent-paper-cup-machine-4.jpg
Control system
Operators can set various parameters such as production speed, temperature, pressure, etc. through the control panel. The control system can also monitor the running status of the machine in real time, and in case of failure, it can send out an alarm and display fault information in time, which is convenient for maintenance personnel to troubleshoot.
Crimping mold
It is used to curl the upper mouth of the paper cup. The shape and size of the crimping die need to match the mouth of the paper cup, and by applying pressure, the paper is rolled smoothly. The quality of these parts directly affects the curling effect of the mouth of the paper cup, such as the flatness and tightness of the curling.
Fan-shaped piece feeding
The paper feeding mechanism discharges the fan-shaped sheet on the paper supply holder through the suction cup, and the conveying mechanism then sends the fan-shaped sheet to the next process
The bottom of the cup is formed
Through the web automatic feeding device and the circular punching mechanism, the bottom of the cup is punched and formed; After the bottom of the cup body is preheated and heated, the bottom of the cup is sealed with the cup body by the bottom rolling device.
High-Speed and Stable Production
The KSJ-120E is engineered for efficiency, delivering a stable and high-speed operation that ensures smooth cup production. With its precision-driven mechanism, manufacturers can achieve a consistent output with minimal downtime, making it a preferred choice for paper cup making machine manufacturers.

Customers' Questions and Answers About Paper Cup Machine

What specific engineering principles allow the KSJ-120E to achieve 110-120 pcs/min while maintaining precision? How is the speed validated?

The KSJ-120E's high-speed precision is driven by a Double Open Type Cylindrical Cam mechanism and Gear Transmission system. This engineering design ensures synchronized, rigid motion with minimal vibration, which is critical for high-speed cup forming and bottom sealing. Speed is validated through continuous 8-hour production runs under full load, measuring consistent output and checking for defects. The linear guide paper sheets conveyor system further ensures stable and accurate paper feeding at this rate.

For a cup with a 110mm top diameter and 180mm height, what is the exact air consumption cost per 10,000 cups? How does the 0.7m³/min spec impact my factory's existing compressed air system?

At 120 cups/min, producing 10,000 cups takes approximately 83.3 minutes. With an air consumption of 0.7m³/min, this equals about 58.3 m³ of compressed air per 10,000 cups. To calculate your cost, multiply this volume by your local cost per m³ of compressed air. This 0.7m³/min rating is considered efficient for its class. You must ensure your air compressor supply has a stable output pressure above the machine's requirement (typically 0.6-0.8 MPa) with sufficient reserve capacity to avoid pressure drops.

What is the changeover process for different tall cup sizes within the 180mm height range?

Changeover involves adjusting the forming mandrel, bottom punch, and cam follower positions. With tooling kits and digital HMI presets, a full changeover for custom large paper cup sizes takes under 30 minutes, minimizing downtime between production runs.

Can you detail the bottom heating system? Why use a Swiss Leister air heater, and how is the temperature uniformity calibrated to prevent seal failure?

The Swiss Leister air heater is selected for its precise PID temperature control (±1°C) and rapid thermal response. Uniformity is ensured through a specially designed nozzle manifold that distributes hot air evenly across the cup bottom seam. Calibration is performed using a thermal imaging camera during setup to create a uniform heat profile. This precise control is critical for strong PE coating sealing, preventing leaks in large-capacity beverage cups like big milk tea or coffee cups.

What is the realistic net production efficiency after accounting for paper roll changes and routine adjustments? What is the typical waste rate?

Net efficiency (OEE) typically reaches 90-94% for skilled operators. A paper roll change can be done in under 3 minutes. The machine's precision in paper cup blank positioning and forming minimizes misalignments. A well-maintained KSJ-120E operating with quality paper can achieve a waste rate (including trim and defective cups) of less than 2.5%. We provide a calculator factoring in your shift patterns to model true daily output.

For producing tall cups (up to 180mm), what specific adjustments or components ensure side seam stability and prevent buckling during high-speed formation?

Producing tall paper cups up to 180mm height requires a stable forming mandrel with precise concentricity and a optimized cup carrier curve. The KSJ-120E uses hardened tool steel mandrels and a cam profile designed to apply gradual, even pressure on the side seam throughout the entire forming path. This prevents rapid stress concentration that can cause buckling in elongated cup designs for items like long ice cream.

What training and technical documentation are provided to in-house engineers for troubleshooting mechanical issues, such as cam positioning or heater fluctuations?

We provide comprehensive training covering operational procedures, preventive maintenance schedules, and level-1 & level-2 troubleshooting. The technical manual includes detailed exploded-view diagrams, a parts list, and step-by-step guides for calibrating the cylindrical cam mechanism and diagnosing heater circuit issues. Remote video support is also available for complex scenarios.

How does the integral machine base contribute to long-term performance and product consistency?

The integral machine base is a single, heavy-gauge steel frame that provides exceptional rigidity. It dampens vibrations from high-speed operation and prevents minute frame flexing. This ensures all critical components—cam, forming stations, sealing heads—maintain perfect alignment over years of use, which is foundational for consistent paper cup quality and dimensional accuracy, batch after batch.

What is the protocol and typical turnaround time for obtaining genuine replacement parts, such as a specific cam follower or heating element?

We maintain a centralized spare parts inventory in Zhejiang. For genuine parts like Leister heater elements or proprietary cam followers, we operate a 24-hour response system for requests. Common wear parts are shipped within 24 hours via express air freight. The exact ETA depends on destination, with common logistics channels established for major industrial regions.

What technical support and training is provided to ensure we achieve the rated 120 pcs/min speed?

DISCOVER provides on-site KSJ-120E commissioning and training, covering optimization for large-cup production, lubrication system management, and preventative maintenance. We ensure your team can sustainably achieve the machine’s rated high-speed output.
