BJC12 Middle Speed Single Turnplate Paper Cup Making Machine

The BJC12 Middle Speed Single Turnplate Paper Cup Making Machine stands out in the mid-scale packaging equipment market through its ingenious structural simplicity and meticulous technical precision, specifically engineered to address the core production needs of small-to-medium cup manufacturers and growing beverage brands. Unlike complex, high-speed machines that prioritize volume over adaptability, the BJC12 strikes a balance between performance and practicality, making it an ideal solution for businesses seeking reliable, cost-effective cup production.

Single Turnplate Core Structure: At the heart of the BJC12 lies an integrated single turntable with 8-position precision indexing, a design that replaces the cumbersome multi-station configurations common in traditional cup-making machines. This streamlined architecture minimizes mechanical friction and wear by reducing the number of moving parts, significantly enhancing operational stability and extending the machine’s service life. Each of the 8 stations on the turntable is fitted with custom-engineered precision molds, calibrated to ensure consistent forming of paper cups with uniform wall thickness, smooth edges, and accurate dimensions. The turntable operates with seamless indexing, enabling continuous, uninterrupted production from paper blank feeding to finished cup discharge—eliminating bottlenecks and reducing material waste caused by misalignment or station transition errors.

Dual PE-Coated Paper Compatibility: The BJC12 is optimized to process a wide range of paper materials, specifically 180-350 grams per square meter (gsm) single or double PE-coated paper. This versatility is critical for meeting the diverse needs of the beverage industry, as PE coating provides essential barrier properties: single PE-coated paper offers cost-effective protection for cold beverages, while double PE-coated paper delivers superior heat resistance and leak prevention for hot drinks. By supporting both variants, the machine ensures that produced cups can reliably hold temperatures ranging from 0°C to 95°C, making them suitable for everything from iced lattes and fruit juices to hot coffee, tea, and even warm soups. The compatibility with high-gsm paper also allows for sturdier cup construction, reducing the risk of deformation or leakage during transportation and use.

Open Cam Transmission System: Departing from traditional gearbox-driven mechanisms, the BJC12 employs an 8-divide open cam transmission system that delivers exceptional motion control. The open cam design translates rotational force into precise, smooth linear movements for each station, ensuring consistent forming, sealing, and bonding across every cup. Unlike gearboxes, which require frequent lubrication and are prone to mechanical failure due to meshing components, the open cam system simplifies maintenance: worn or damaged cams can be easily accessed and replaced by on-site workers without the need for specialized technical training or complex tools. This design not only reduces downtime but also lowers long-term maintenance costs by minimizing the risk of cascading mechanical issues.

Multi-Sensor Monitoring Network: To guarantee production quality and safety, the BJC12 integrates a comprehensive network of 11 dedicated sensors strategically placed throughout the machine. These sensors monitor critical production parameters in real time, including paper blank feeding accuracy, sealing temperature, pressure, cup wall thickness, and discharge efficiency. For example, paper feeding sensors detect misaligned or jammed blanks, while temperature sensors ensure ultrasonic sealing and hot-air bonding operate within optimal ranges to prevent under-sealing (leakage) or over-sealing (material damage). When an anomaly is detected—such as a temperature deviation of more than 5°C or a paper jam—the system triggers an immediate automatic shutdown, accompanied by visual and audible alarms. This proactive monitoring minimizes material waste, protects the machine from damage, and ensures that only high-quality cups reach the end user.

The BJC12’s competitive edge in the mid-scale cup production market stems from its exceptional equilibrium of speed, reliability, and cost-effectiveness—three factors that directly impact production return on investment (ROI) for small-to-medium businesses. Unlike high-speed machines that require significant energy input and specialized maintenance, or low-speed machines that struggle to meet growing demand, the BJC12 is engineered to optimize efficiency without compromising affordability.

Stable Middle-Speed Output: The machine maintains a consistent production rate of 70-80 cups per minute, a speed perfectly aligned with the demand of mid-sized beverage brands, regional packaging companies, and independent cafes. This output level eliminates the need for overcapacity—common with high-speed machines that produce 100+ cups per minute but consume 50% more energy—while ensuring businesses can meet peak demand periods (e.g., morning coffee rushes or event catering) without delays. The stability of the output is equally important: the single turntable design and precision indexing ensure that each cup is produced to the same standard, reducing reject rates to less than 0.5%—a significant improvement over multi-station machines with typical reject rates of 2-3%.

Low Maintenance Cost: The BJC12 is built with standardized, highly interchangeable components, sourced from global suppliers to ensure easy availability and affordability. This design choice simplifies repairs, as replacement parts (such as cams, molds, or sensors) can be quickly sourced and installed without lengthy downtime. Additionally, the machine features an automatic lubrication system that delivers precise amounts of oil to key mechanical components—including the turntable bearings and camshaft—at regular intervals. This eliminates the need for manual lubrication, reduces friction-related wear, and extends the lifespan of critical parts. The open cam design further lowers maintenance requirements: workers can inspect, clean, or replace cams in less than 30 minutes, without the need for professional technicians or specialized tools, cutting labor costs and minimizing production interruptions.

Energy and Space Efficiency: Designed with small-to-medium workshops in mind, the BJC12 operates at a modest 3.5kW working power—significantly lower than high-speed machines that consume 5-7kW. This energy efficiency translates to substantial monthly cost savings on electricity bills, especially for businesses operating the machine for 8-12 hours per day. The machine’s compact footprint (2250×1230×1950mm) also makes it easy to integrate into existing production lines or small workshops, requiring minimal floor space compared to multi-station machines that often occupy 30% more area. A key advantage is the elimination of the need for an external air compressor: the BJC12’s integrated pneumatic system reduces auxiliary equipment costs by up to $2,000 and eliminates the noise and maintenance associated with standalone compressors.

User-Friendly Operation: The BJC12 is equipped with a state-of-the-art Human-Machine Interface (HMI) and Programmable Logic Controller (PLC) system, designed to simplify operation for workers with minimal technical training. The intuitive touchscreen interface displays real-time production data, including total cup count, current speed, error logs, and maintenance reminders. Operators can easily adjust key parameters—such as sealing temperature, turntable speed, and cup size—with just a few taps, allowing for quick changeovers between cup specifications (e.g., switching from 8oz to 16oz cups in less than 15 minutes). The PLC system also stores production profiles for commonly used cup sizes, enabling one-touch setup and reducing the risk of human error. Built-in safety features, such as emergency stop buttons and door interlocks, further enhance usability by ensuring operator safety during operation.

The BJC12 integrates a complete suite of automated functions, designed to transform raw PE-coated paper blanks into finished, ready-to-use cups through a seamless, hands-free production process. From paper handling to final inspection, each function is optimized for precision, efficiency, and consistency.

Precision Paper Handling: The machine’s paper feeding system uses vacuum-assisted suction with an anti-withdrawal device to ensure accurate positioning of paper blanks. The vacuum system gently lifts individual blanks from the feed tray, while the anti-withdrawal mechanism prevents double-feeding or misalignment—common issues that cause size deviations or production jams. The paper handling system is adjustable to accommodate different blank sizes (3-16 oz), and the vacuum pressure can be fine-tuned based on paper gsm, ensuring reliable feeding for both thin (180 gsm) and thick (350 gsm) materials. This precision eliminates waste caused by misfed blanks and ensures that each cup is formed to the correct diameter and height.

Ultrasonic Sealing & Hot-Air Bottom Bonding: For leak-proof performance, the BJC12 uses ultrasonic welding to seal the side seams of each cup. Ultrasonic technology creates a strong, uniform bond by generating high-frequency vibrations that melt the PE coating, fusing the paper layers together without the need for adhesives. This process ensures that seams are resistant to both hot and cold liquids, preventing leakage even when cups are filled to capacity. The machine also employs hot-air heating for cup bottom knurling—a process that enhances adhesion strength between the cup body and bottom. The hot-air system is temperature-controlled to match the PE coating’s melting point, ensuring a secure bond that withstands transportation and handling without separation.

Automatic Lubrication & Cooling: To maintain optimal performance, the BJC12 features a closed-loop automatic lubrication system that delivers clean, filtered oil to key components (turntable bearings, camshaft, and indexing mechanism) at preset intervals. This continuous lubrication reduces friction and wear, extending component life and minimizing maintenance. For processing double PE-coated paper— which generates more heat during sealing—the machine offers an optional water-cooling module. This module circulates cooled water through the sealing and forming stations, preventing overheating and ensuring consistent bonding quality, even during extended production runs.

Intelligent Fault Protection: The BJC12’s intelligent fault protection system is designed to prevent material waste and machine damage by detecting anomalies in real time. When sensors identify issues such as paper jams, temperature fluctuations, mold misalignment, or low lubricant levels, the system immediately stops the machine and activates audible and visual alarms. The HMI display shows a detailed error message, guiding operators to the source of the problem for quick resolution. This proactive protection minimizes the risk of producing defective cups, reduces material waste (a critical cost factor for small businesses), and prevents costly damage to precision components—such as molds or ultrasonic transducers.
