Multi-Head Weighing Vertical Packaging Machine (100–2000g)
This integrated multi-head scale vertical form-fill-seal (VFFS) packaging system represents a pinnacle of automated efficiency for medium-to-large weight bagging operations. Engineered specifically for the high-speed packaging of free-flowing and semi-regular items such as particles, tablets, and irregular solids, it seamlessly unifies a Z-type bucket elevator, a precision 14-head combination weigher, and a robust vertical packaging machine into a single, synchronized production line. The system is designed to handle a versatile weight spectrum from 100 to 2000 grams, delivering stable material feeding, exceptionally fast and accurate weighing, and the consistent production of high-integrity back-seal bags from a wide array of composite packaging films. Governed by a sophisticated PLC-based control system and featuring servo-driven film transport alongside pneumatic horizontal sealing, this machine offers factories a reliable solution to significantly boost throughput, minimize product giveaway, and reduce reliance on manual labor, ensuring a rapid return on investment.
Product Features
The machine’s design philosophy centers on operational flexibility, precision, and durability, offering distinct advantages that set it apart in demanding production environments.
Broad Production Flexibility
With its extensive 100–2000g packaging range, this system effortlessly accommodates a diverse portfolio of product SKUs. It is perfectly suited for snacks, agricultural goods, hardware components, and pharmaceutical tablets, eliminating the need for multiple dedicated packaging lines and simplifying production planning for manufacturers with varied product weights.
Precision Combination Weighing
At its core, the HX-A14 14-head combination scale performs rapid computational analysis to select the optimal hopper combination for each discharge cycle. This advanced technology achieves remarkable system accuracy, typically within ±0.5% to ±1% of the target weight, with weigher-specific precision reaching approximately ±0.5–2 grams. This high level of accuracy directly translates to reduced material overfill and consistent package weight compliance.
Consistent and Clean Material Handling
A dedicated CST-D10-3600 Z-type bucket elevator ensures a smooth, uninterrupted flow of product into the weigher’s inlet hopper. Equipped with variable-frequency drive and a capacitive level sensor, it maintains optimal feed rates. Optional integrated features, including a magnetic rod for ferrous metal removal and a sediment vibrator, enhance final product cleanliness for sensitive applications.
High-Speed Servo-Controlled Bag Making
Bag formation is driven by a high-response servo motor, which pulls the packaging film with exceptional consistency and control. This technology enables packaging speeds ranging from 20 to 40 bags per minute, striking an ideal balance between high output and operational stability, which is crucial for larger-weight packaging tasks.
Robust and Reliable Sealing Performance
The system utilizes a back-seal bag structure, renowned for its strength and superior moisture barrier properties. It employs a side-sealing, single-action design for the vertical seal and a pneumatically actuated system for the horizontal seal. This combination ensures uniform pressure and heat application, resulting in strong, hermetic seals across various film types and bag dimensions.
Intuitive Control and Smart Diagnostics
Operation is streamlined through an Inovance 7-inch color touchscreen interface paired with a robust PLC. The system allows for easy parameter adjustments, provides clear visual error prompts, and includes self-diagnostic functions. Bag length can be precisely controlled via photoelectric color mark tracking for printed films or set directly via the touchscreen for plain films, facilitating quick changeovers.
Hygienic and Long-Lasting Construction
Built for longevity and easy maintenance, all product-contact surfaces are constructed from corrosion-resistant 304 stainless steel. Major external frames and panels also utilize 304 stainless steel or lightweight aluminum alloy. This construction not only meets stringent hygiene standards for food and pharmaceutical production but also ensures durability in challenging industrial atmospheres.
