I. Product Overview

ZHD-T02 Bag Filling and Weighing System is a premium, fully automated pre-made bag packaging solution. It combines a high-precision computer weigher with a rotary bag feeder to deliver end-to-end automation—from loading and precise weighing to dosing, sealing, date coding, and finished product conveyance. Utilizing proven rotary bag technology and standard pre-made bags, the system ensures neat, professional packaging that elevates brand presentation. It supports diverse bag materials and complex shapes, offering superior automation, quality, and versatility compared to conventional vertical form-fill-seal machines. With stable operation, accurate metering, and high throughput, it integrates seamlessly into production lines—making it the ideal choice for mid-to-high-end standardized packaging in food, hardware, and plastics industries.

II. Equipment System Composition

The complete system operates via six core modular components working in synergy, featuring a stable structure and easy assembly, disassembly, and maintenance.

1. Vibrating Feeder: Delivers material at a consistent, uniform rate to effectively prevent blockages, shortages, and bridging, ensuring a continuous and stable feeding process.

2 Z-Type Elevator: Enclosed bucket elevator design ensures a clean, dust-free environment and smoothly transports raw materials to the multihead weigher hopper, supporting continuous production.

3. Work Platform: A sturdy platform designed to support the computer combination weigher, providing a convenient workspace for equipment calibration, routine maintenance, and servicing.

4. Computer Multihead Weigher: High-precision dynamic weighing, intelligent sorting, and automatic rejection of out-of-spec weights to ensure accurate bagging.

5. Rotary Form-Fill-Seal Machine: The core host equipment that automatically performs bag picking, opening, filling, sealing, coding, and discharge for various pre-made bags.

6. Finished Product Conveyor: Automatically transports packaged goods directly to downstream packing and sorting operations, enabling automated assembly line production.

3. Key Product Features

1. Fully automated workflow: The equipment automatically handles feeding, precise metering, filling and sealing, date printing, and finished product conveyance. With zero manual intervention, it significantly reduces labor costs and boosts production efficiency.

2. Precision and High Efficiency: Equipped with a high-precision multihead weigher for minimal dynamic weighing error and exceptional stability, enabling continuous high-speed operation and consistent output to meet large-scale production demands.

3. Highly versatile material compatibility: handles granules, flakes, strips, and irregular shapes across food, pet products, hardware, plastics, and more.

4. Premium Pre-made Pouch Packaging: Utilizes high-quality pre-formed bags, eliminating the need for on-site bag making. Features exquisite designs and consistent shaping to elevate product appeal at the point of sale and boost market competitiveness.

5. Superior Sealing Quality: Features precisely adjustable sealing time for smooth, secure, wrinkle-free, and leak-proof seals. Ensures optimal product shelf life.

6. Versatile packaging material compatibility: Fully supports paper-plastic laminates, plastic-plastic laminates, aluminum-plastic laminates, PE laminates, multi-layer composite films, aluminum foil, single-layer PE/PP, and ultra-thick films.

IV. Supported Bag Types

Compatible with mainstream high-end pouch types on the market. Easily switch between configurations to meet diverse packaging needs: zipper bags, stand-up pouches, edge-printed bags, four-side seal bags, three-side seal bags, custom-shaped bags, and hang-hole bags.

V. Optional Auxiliary Equipment and Functional Details

1. Weight Inspection Machine: Re-weighs finished bags to automatically and precisely reject underweight or overweight products. It also tracks yield statistics to support quality control management. No additional configuration is needed if a combined metal detection and weight inspection unit is already in place.

2. Horizontal Metal Detector: Designed for inspecting finished, packaged products to precisely detect metal contaminants such as iron and stainless steel. Ensures strict quality control at the final stage and prevents after-sales issues.

3. Drop-through Metal Detector: Installed at the equipment's discharge point to perform in-line metal detection on materials before packaging. It removes foreign objects early, reducing downstream rework and waste, while occupying no additional floor space—only slightly increasing the production line's installation height.

4. Metal Detection and Re-weighing All-in-One Machine: Combines metal contamination detection with finished product weight verification in a single unit, replacing two separate machines. This reduces equipment procurement costs, saves floor space, and simplifies setup and ongoing maintenance.

5. Disc Sorter: Aggregates finished products on the production line. Ideal for scenarios requiring manual secondary sorting, repackaging, or temporary storage, bridging upstream and downstream processes.

6. Finished Product Conveyor: Adjustable height for seamless integration with downstream processes, accommodating diverse production line layouts.

VI. Core Product Advantages

1. Premium packaging: Pre-formed pouches offer a 3D, elegant design with crisp, high-end graphics and secure, flat seals. Unlike traditional bag-making, this solution meets the branding needs of mid-to-high-end products.

2. Broader application scenarios: Compatible with various materials, bag types, and substrates to meet diverse packaging needs across industries such as snacks, pet food, hardware, and plastics.

3. Precision and Efficiency in Mass Production: Equipped with a high-precision multihead weigher, this system ensures minimal weighing errors and a high pass rate. Designed for stable continuous operation, it delivers high-speed output to meet large-scale production demands.

4. Effortless Operations: Modular design with organized equipment layout ensures simple commissioning, maintenance, and cleaning. Low failure rates significantly reduce production operational costs.

5. Highly adaptable conveyor system: seamlessly integrates with various auxiliary machines to unify foreign object detection, weight sorting, and finished product handling for automated, unmanned production lines.
