Key Features
1. Anti-Stick Heated Sealing Jaw System
The JY-ZB1500 incorporates a purpose-designed sealing jaw assembly with proprietary non-stick surface treatment that prevents toffee residue, chocolate oils, and sugar-based contaminants from adhering during high-speed operation. The temperature control system supports settings up to 180°C with digital precision, enabling operators to dial in optimal sealing parameters for different film materials — from standard BOPP to metallized and laminated composite films. This anti-stick capability translates directly into reduced downtime for jaw cleaning, extended seal component life, and consistently hermetic seals across production shifts lasting 8 hours or more.
2. 3-Servo Precision Drive System
Three independent servo motors govern the film feeding, longitudinal sealing, and transverse sealing/cutting operations respectively. This architecture enables real-time synchronization adjustments without mechanical cam changes, allowing product changeovers to be completed in under 15 minutes. Each servo drive maintains positional accuracy within ±0.5 mm, ensuring that printed film registration marks align perfectly and that cut-off positions remain consistent throughout the entire speed range of 50 to 800 packs per minute. The servo system also contributes to the machine's energy efficiency, drawing only 5.0 KW at full production speed.
3. Wide Product Compatibility Range
The JY-ZB1500 accommodates a bag width range of 40 to 150 mm, making it suitable for products ranging from miniature toffee pieces to full-size chocolate bars. The adjustable forming tube and film roll carriage support standard film roll widths up to 350 mm, with quick-change mechanisms that minimize tooling time. The infeed conveyor is configured with adjustable guide rails that can be set for different product dimensions — round, square, rectangular, or irregular shapes — without requiring specialized tooling for each product variant. This flexibility is essential for contract packagers and confectionery manufacturers who run multiple SKUs on a single line.
4. Photoelectric Film Tracking and Registration
A high-sensitivity photoelectric sensor continuously monitors printed registration marks on the packaging film, automatically compensating for any drift in the film feed path. The system responds within milliseconds to maintain eye-mark alignment, ensuring that printed graphics, date codes, and branding elements appear in the correct position on every single pack. For clear or unprinted films, the machine can be switched to a fixed-length mode where cut-off positions are determined by encoder pulses from the main servo drive, providing equally consistent results for plain film applications.
5. Stainless Steel Frame and Food-Grade Construction
All product-contact surfaces and the main machine frame are constructed from 304 stainless steel, complying with international food safety standards for confectionery packaging equipment. The frame is fully welded and polished to a smooth finish that resists corrosion and simplifies cleaning. Electrical enclosures are rated IP54 or higher, protecting internal components from dust and moisture ingress in production environments. The open-frame design provides unrestricted access to all critical zones — film path, sealing area, infeed, and discharge — facilitating routine cleaning and maintenance without requiring disassembly.
6. Intelligent Touch Screen Control with Multi-Language Interface
The PLC-driven 7-inch color HMI touch screen provides a centralized control panel where operators can configure, monitor, and diagnose every function of the JY-ZB1500. Parameter presets for up to 50 product recipes can be stored and recalled instantly, eliminating the need to re-enter settings for recurring production runs. The interface supports English, Chinese, Spanish, French, Arabic, and Russian, reflecting Junyao's global customer base. Built-in diagnostic tools report fault conditions with plain-language descriptions and suggested corrective actions, reducing mean time to repair for common operational issues. Remote access capability via Ethernet port is available as an option for real-time production monitoring and off-site troubleshooting.
