ZHD-T02|Automatic Multihead Weighing Packaging Line

I. Product Overview

The ZHD Combination Weigher Packaging System is a fully automated, multi-head precision weighing and packaging solution. Built on a high-accuracy computerized multihead weigher integrated with a vertical packaging machine, it delivers end-to-end automation for automatic feeding, precise weighing, metered filling, bag forming, sealing, date printing, and finished product conveyance. With fast weighing speeds and exceptional combination accuracy, the system handles granular, chunky, and irregularly shaped products. Engineered for stable operation and seamless integration with downstream production lines, it is widely used in food, hardware, plastics, and snack manufacturing industries.

II. Equipment System Composition

The entire system operates through modular collaboration of multi-core components, featuring a stable structure and easy assembly, disassembly, and maintenance.

Vibrating Feeder: Delivers consistent, uniform material flow to effectively eliminate blockages, shortages, and bridging, ensuring a stable and continuous feeding process.

Z-Type Elevator: Enclosed bucket elevator design for dust-free, smooth raw material transfer to weigh hopper, supporting continuous production.

Computer Multihead Weigher: Core weighing unit with multi-hopper combinatorial weighing, rapid material sorting, dynamic weight deviation compensation, and guaranteed metrological accuracy.

Vertical Packaging Machine: Performs bag making, opening, filling, sealing, coding, and discharge to form and seal the packaging.

Work Platform: Sturdy support for multihead weighers, providing convenient access for equipment setup, routine maintenance, and servicing.

Finished Product Conveyor: Automatically transports packaged goods and directly interfaces with downstream packing and sorting operations to enable automated assembly line production.

3. Key Product Features

Fully automated workflow: The equipment automatically handles feeding, weighing, filling and sealing, date printing, and finished product discharge without manual intervention. This reduces labor costs and boosts production efficiency.

Precise weighing, high-capacity efficiency: Multi-head combination scale with multi-bucket computation delivers minimal weighing error and rapid response for high-speed continuous operation, meeting large-scale production demands.

Wide Material Compatibility: Handles pellets, flakes, strips, and irregular shapes across industries including snacks, pet products, hardware, and plastics.

Easy-to-clean整机: Contact parts are made of 304 stainless steel, feature simple disassembly for easy rinsing and cleaning, and meet food production hygiene standards.

Excellent seal quality: Adjustable sealing time and temperature produce flat, secure seals without wrinkles or leaks, ensuring optimal product shelf life.

Intelligent Parameter Storage: Save multiple material recipes and instantly load parameters when switching materials. Equipped with fault alerts to quickly identify equipment issues and minimize downtime.

IV. Supported Bag Types

Compatible with all major bag types—back seal, three-side seal, four-side seal, punched, and continuous rolls—to meet diverse packaging needs for composite film bags.

V. Optional Auxiliary Equipment and Functional Details

Weight Re-Check Machine: Re-checks finished bags for weight accuracy, automatically rejects underweight or overweight products, and collects good product statistics to support production quality control. Integrates seamlessly with the metal detection and re-checking combined unit—no redundant configuration required.

Horizontal Metal Detector: Inspects finished products after packaging to precisely detect ferrous and stainless steel contaminants, ensuring strict quality control at the point of shipment and preventing post-sales issues.

Drop-type Metal Detector: Installed at the equipment discharge point to perform in-line metal detection on materials before packaging. It removes foreign objects early, reducing downstream rework and losses, while occupying no additional floor space and adding minimal height to the production line.

All-in-One Metal Detection and Re-weighing Machine: Combines metal contamination detection with final product weight verification in a single unit. Replaces two separate machines, reducing equipment procurement costs, saving floor space, and simplifying setup and ongoing maintenance.

Disc Sorting Machine: Collects and organizes finished products on the production line. Ideal for scenarios requiring manual secondary sorting, repackaging, or temporary storage, seamlessly connecting upstream and downstream processes.
