How Multi-Head Weighers Work: The Complete Guide

Introduction for multi-head weigher of vertical machine

Multi-head weigher, also called combination scales, have revolutionized weighing technology across industries – from food processing to hardware and chemical manufacturing. If you’re new to automated weighing systems, understanding how these precision instruments operate can help optimize your packaging line.

Multi-head weigher core working principle

At its heart, a multi-head weigher uses advanced software algorithms to achieve perfect portion control. Here’s the step-by-step process:

1. Product Feeding in granule packing machine

   • Bulk products enter through the infeed funnel via elevators/conveyors

   • The vibrating top cone and feeding tray distribute material evenly

2. Smart Distribution

   • Products move toward the edge via vibration

   • Special dimpled surfaces prevent sticking (ideal for sticky items like candy)

3. Precision Weighing

   • Each of the 10-24 weigh buckets contains an independent load cell

   • All buckets continuously weigh their contents during operation

4. Optimal Combination Selection

   • The computer analyzes all possible bucket combinations

   • Selects the group that sums closest to your target weight

   • Example: For 100g target, might combine buckets 1+3+10+12

5. Discharge & Repetition

   • Selected buckets discharge product into packaging

   • System immediately recalculates for next weighing cycle

Key Advantages of Combination Multi-head Weighers

• Firstly Unmatched Speed – Processes up to 120 weighments/minute
• Secondly Precision Accuracy – Achieves ±0.01-0.02g consistency
• Thirdly Product Protection – Gentle handling preserves fragile items
• Fourthly Labor Savings – Replaces 4-6 manual operators
• Finally Versatility – Handles products from 1g to 5kg

Choosing the Right Configuration

Pro Tip: Sticky products require special textured stainless steel buckets, while fragile items need vibration-adjustable systems.
