Multi-Head Weighing Vertical Packaging Machine (100–2000 g)
Engineered for high-throughput, high-consistency production, this Multi-Head Weighing Vertical Form-Fill-Seal (VFFS) system delivers an integrated solution for weighing and bagging free-flowing particles, tablets, and irregular yet weighable products. The line combines a CST-D10-3600 Z-type bucket elevator, an HX-A14 14-head combination weigher, and a servo-driven vertical packaging machine into one coordinated unit, creating a stable “feed–weigh–form–fill–seal” workflow. Built for medium-to-large pack sizes from 100 to 2000 grams, the system minimizes manual handling while maintaining dependable dosing performance and clean, uniform back-seal bags across a broad range of composite packaging films. PLC-based control, touchscreen operation, photoelectric tracking, and pneumatic sealing provide a balanced platform for factories seeking scalable output, reduced giveaway, and repeatable packaging quality.
Product Features
Broad 100–2000 g Weight Capability
Designed to cover common retail and bulk SKUs, the 100–2000 g range supports flexible production planning for multiple pack sizes without frequent line changes. From 100 g trial packs to 2 kg family-size or industrial packs, the system helps consolidate equipment needs and improves utilization across varied product portfolios.
High-Precision 14-Head Combination Weighing
The 14-head combination weigher performs rapid multi-bucket calculations to select optimal weight combinations per cycle. System-level accuracy typically reaches ±0.5% to ±1% (subject to product characteristics and target weight), while the weigher can achieve approximately ±0.5–2 g accuracy depending on flowability, granule size, and speed settings. This supports tighter weight control, reduced overfill, and more stable cost performance during long runs.
Consistent Infeed with Z-Type Bucket Elevator
The Z-type bucket elevator provides continuous, controlled conveying to the scale inlet hopper, helping maintain stable weighing rhythm and reducing starvation or overfeeding events. Variable-frequency speed regulation and a capacitive level device coordinate feeding intensity with downstream demand. For applicable materials, optional chip/iron removal (magnetic rod plus sediment vibrator) assists with product conditioning and cleanliness prior to weighing.
Servo Film Pulling for Stable Bag Length and Output
Servo motor belt pulling ensures steady film transport and accurate bag length control, improving bag consistency during high-speed operation. Typical output is 20–40 bags per minute, depending on bag length, material behavior, and film performance—offering an efficient speed range for large-weight vertical packaging where stability is essential.
Strong, Repeatable Sealing on Composite Films
The back-seal bag structure supports a clean appearance and stable sealing strength across many laminated and composite films. Vertical sealing uses a side-sealing single-action structure for reliable longitudinal closure, while pneumatic horizontal sealing delivers consistent pressure for uniform end seals. This combination helps reduce seal defects, supports dependable shelf performance, and improves overall packaging integrity.
PLC + Touchscreen Operation with Tracking and Diagnostics
The control platform integrates an Inovance PLC with a 7-inch color touchscreen for quick parameter setup, alarm prompts, and self-diagnostic functions. Bag length can be controlled via photoelectric color-mark tracking for printed films or by direct length settings on the touchscreen for unprinted films, enabling fast changeovers and smoother day-to-day operation.
304 Stainless-Steel Product Contact for Hygienic Production
All product-contact parts are made of 304 stainless steel to support corrosion resistance and easier cleaning. Exposed machine surfaces are constructed from 304 stainless steel or aluminum alloy (excluding moving parts), improving durability in demanding production environments and helping maintain stable, long-term performance.
