GD-380A Fully Automatic Bag Feeding and Packaging System
The GD-380A represents a state-of-the-art, fully integrated solution for the automated packaging of weighable granular, tablet, and irregular-shaped products into premade pouches. Engineered as a complete line, it seamlessly integrates an 8-station rotary bag feeder with a high-precision multihead combination scale to orchestrate the entire packaging sequence—from bag picking and opening to precise filling, air exhausting, hermetic sealing, and final discharge. Constructed with industrial-grade 304 stainless steel on all product-contact surfaces and driven by a sophisticated PLC control system, the GD-380A delivers exceptional operational stability, consistent seal quality, and repeatable weighing accuracy, making it a robust and reliable cornerstone for high-demand production environments.
Product Features
End-to-End Premade Pouch Automation
The system automates the complete packaging workflow. Once premade pouches are loaded into the magazine, the machine autonomously picks, opens, and positions each bag. Upon receiving the ready signal, the combination weigher dispenses the precise product weight, after which the pouch is exhausted of air, sealed, and conveyed out as a finished package. This seamless automation significantly reduces manual intervention, minimizes labor dependency, and ensures unparalleled process consistency and hygiene.
High-Efficiency Rotary Design for Stable Output
At the heart of the GD-380A is its robust 8-station rotary mechanism, powered by a precise mechanical cam transmission system. This design guarantees smooth, synchronized station-to-station transfer and repeatable operational timing, enabling continuous, high-speed production. The system reliably achieves speeds ranging from 10 to 30 bags per minute, with a typical target output configured between 15-35 packs/min, adaptable to specific material characteristics, bag formats, and fill weights.
Precision Weighing for Diverse Product Forms
Paired with the HX-A14 14-head waterproof combination weigher, the line excels in accurate dosing across a broad spectrum of products. It handles packaging weights from 100 to 2000 grams with typical accuracy within ±0.5% to ±1%, contingent on product properties. This capability makes it perfectly suited for items of mixed sizes and irregular shapes that demand strict net weight control and consistency.
Intelligent and Reliable Sealing Performance
The system incorporates a pneumatic sealing system with a dual-sealing device arrangement to ensure strong, reliable seals. Intelligent detection logic ensures that filling and sealing only proceed when a bag is correctly presented, preventing product waste and film contamination. An integrated sponge exhaust mechanism actively removes air from the pouch before sealing, enhancing package appearance, prolonging shelf life, and minimizing headspace.
Advanced Control for Operational Excellence
Centralized control is provided through a Siemens color touchscreen HMI and a Siemens PLC, offering user-friendly operation, comprehensive alarm prompts, and self-diagnostic functions. Two-way temperature control on the horizontal sealers maintains consistent seal quality across various pouch materials. The use of premium components from Schneider/OMRON (electrical) and AIRTAC (pneumatics) ensures long-term system stability, ease of maintenance, and faster changeovers.
Hygienic Construction with Food-Grade Materials
Designed with cleanliness in mind, all parts in contact with the product are fabricated from corrosion-resistant 304 stainless steel, meeting stringent hygienic standards for food and pharmaceutical applications. Exposed machine surfaces also predominantly utilize 304 stainless steel or aluminum alloy, facilitating easy cleaning and maintenance while presenting a professional, food-grade aesthetic.
