Semi-Automatic Double Head Weigher Packaging Machine | Dual Hopper Granule Weighing & Filling Equipment
Share to:
This semi-automatic double head weigher packaging machine is designed for accurate quantitative packaging of granular materials, suitable for particle sizes up to walnut-sized products. The machine adopts a dual weighing hopper structure with vibratory feeding assistance, ensuring stable material flow and precise weighing. The discharge outlet can be connected directly to bags, buckets, jars, or containers, providing flexible packaging solutions for different product formats. Ideal for industries requiring reliable weighing performance, simple operation, and efficient semi-automatic filling.
Machine Overview and Functional Description
The semi-automatic double head weigher packaging machine is engineered for high-accuracy weighing and filling of free-flowing granular materials. Designed with a dual-hopper alternating weighing system, the machine delivers fast discharge speed, stable operation, and precise weight control for medium-to-large particle materials.
The feeding system adopts a vibratory feeding mechanism, where two independent vibratory feeders are installed above each weighing hopper. Materials are continuously delivered into the weighing hopper through controlled vibration. The rear side of each hopper is equipped with a high-precision weighing module, enabling real-time weight monitoring. Once the preset target weight is reached, the vibratory feeders automatically stop feeding to ensure accurate filling.
Constructed from food-grade stainless steel, the machine offers excellent corrosion resistance, hygienic performance, and easy cleaning. The system is equipped with a PLC touch-screen control interface, featuring an intuitive operation system for convenient parameter adjustment and reliable machine control.
The machine supports dual-speed feeding (fast and slow feeding modes) to improve weighing accuracy and adapt to different material characteristics. Operators can choose between photoelectric switch activation or foot pedal operation, offering greater operational flexibility.
The transparent acrylic protective cover allows easy observation of the weighing process while maintaining safety and dust prevention. The open-frame structure provides convenient maintenance and fast cleaning.
Designed for semi-automatic operation, the discharge outlet can connect to bags, bottles, jars, drums, or rigid containers, making it suitable for a wide range of packaging applications.

Structural Design and Working Principle
1. Dual Vibratory Feeders for Each Weighing Hopper
Each weighing hopper is equipped with two independent vibratory feeders, ensuring stable and uniform material feeding. The dual-feeding design improves dosing precision and prevents inconsistent material flow during weighing.
2. Intelligent PLC Control System
The machine features a PLC touch-screen control system with a user-friendly operating interface. Parameters such as target weight, feeding speed, and weighing mode can be adjusted easily for efficient operation.
3. Alternating Dual-Hopper Discharge System
The dual weighing hoppers work alternately, significantly improving packaging efficiency and discharge speed. While one hopper is discharging, the other hopper simultaneously performs weighing for continuous operation.
4. Adjustable Discharge Outlet
The discharge outlet features an adjustable opening design, allowing flexible adaptation to different bag sizes, jars, buckets, and containers, improving compatibility across various packaging formats.

FAQs
Q1: What materials can this double head weigher package?
This machine is suitable for free-flowing granular materials, including seeds, rice, mixed grains, fertilizer granules, detergent granules, veterinary medicine particles, snack foods, and small hardware components.
Q2: What is the maximum material size this machine can handle?
The machine is recommended for granular materials not exceeding walnut size, ensuring stable feeding and accurate weighing performance.
Q3: How does the machine achieve weighing accuracy?
The machine combines dual vibratory feeding technology with real-time electronic weighing modules, automatically stopping material feeding once the preset weight is reached.
Q4: Can the machine fill both bags and containers?
Yes. The machine can discharge into bags, jars, drums, bottles, or rigid containers, and the outlet size can be adjusted according to packaging requirements.
Q5: Is this machine fully automatic?
No. This is a semi-automatic packaging machine. Operators manually position bags or containers, while the weighing and discharge process is completed automatically.
