Linear Weigher

Accurately weigh and dispense free-flowing and semi-free-flowing dry products into diverse containers for a wide range of industrial packaging applications.

Industrial Multi-Lane Linear Weighing Machines for Bulk Solids

A linear weighing machine is a high-precision net weigher that calculates actual mass rather than volume. It uses vibratory pans and load cells to meter dry bulk goods to the exact target weight before feeding them into flexible packaging or rigid containers. This specialized process is why the equipment is also known as a vibratory weigh filler.

Anxine linear weighers optimize your production workflow with advanced, user-friendly automation. Our systems utilize PID3 and PID4 control to ensure precise weighing. With a high-capacity design, you can achieve target weights up to 13,000g per single dump. Additionally, our independent weigh buckets allow you to blend up to four distinct ingredients simultaneously into a single container.

Why Choose Anxine Linear Weighers

Struggling with inconsistent filling? We build linear weighers with high accuracy to support consistent packaging outputs. Each model is configured to your target weight and designed to integrate into high-speed packaging lines.

Precise Weighing and Filling

Automatically switch from bulk filling to a dribble feed based on real-time load cell feedback. Minimize target weight variation and reduce costly product giveaway.

Versatile Material Handling

Handle multiple recipes or heavy fills using bucket combinations. You can program the discharge time to prevent chute blockages during simultaneous product release.

Flexible Line Integration

A CAN bus architecture enables each weigh bucket to work independently and allows the equipment to connect with a VFFS bagger or a premade pouch machine for a synchronized line operation.

Tool-Less Changeover and Maintenance

Quick-release weigh buckets, waterproof vibratory pans, and one-touch auto purge support fast changeover and cleaning without extra tools.

How A Linear Weigher Works

Linear net weighers operate by weighing bulk materials using load cells and dispensing the target weight with multi-stage vibration.

Product Loading

Bulk materials are loaded into the top hopper and gravity-fed onto the feeding pans below.

Sectioned Feeding

The pans vibrate to move the material into the weigh buckets. The system first performs a rapid bulk feed, then automatically switches to a dribble feed until it reaches the target weight.

Real-Time Weighing

A load cell under each bucket measures the weight of the incoming material. The weight data is instantly sent via the CAN bus to regulate vibration amplitude.

Product Discharge

Once the target weight is achieved, the weigh bucket doors open to release the measured product directly into the bagging or bottling line.

FAQs about Linear Weighing Machines

Q: What is the difference between a linear weigher and a multi-head weigher?

Linear weighers feed product through vibratory pans into weigh buckets positioned in a straight line. They offer a simpler and more economical weighing solution. Multi-head weighers are faster and more accurate systems. They also use weigh buckets in a circular arrangement. The target weight is reached by calculating the best combination of weights from the buckets.

Q: Can your linear weigh filler mix different ingredients into a single pouch?

Yes. Each weigh bucket on our weigher can be configured with its own product parameters. They also support staggered discharge timing to prevent chute clogging when different ingredients in your mixed recipe are released simultaneously.

Q: Can I package target weights larger than the hopper volume?

Yes. You don’t need a larger machine. Our linear weighers feature multi-discharge and combined-discharge functions. The system performs several bulk fills followed by a final micro-feed to hit massive target weights.

Q: Can linear weighers handle sticky or wet products?

No, standard weighers are designed for dry, free-flowing materials because sticky or wet products can cling to the vibratory pans and weigh buckets, which can affect weighing accuracy.

Q: How do you clean the weigh filler?

Our machines use a completely tool-less design. You can use a one-touch purge function to clear residues, then manually detach the quick-release weigh buckets and vibratory pans for rapid washdowns.
