Multi-head weigher packaging machines can be classified by metering type into volumetric cup type, mechanical scale type and electronic scale type. By feeding drive mode, they are categorized into self-locking vibrator type and digital motor type.
A complete packaging production line can be equipped with auxiliary packaging equipment such as mixers, feeders, check sorter scales, case packers, palletizers, etc. Let’s learn about the working principle and core advantages of multi-head weigher packaging machines.
There are various types of multi-head weigher packaging machines. Their core function is filling materials and sealing containers with accurate weighing, firm sealing and attractive finished appearance.
Multi-head weigher packaging machines for food applications are increasingly widely adopted in the packaging industry. The 8 key advantages are listed below:
1. Greatly improved production efficiency with much higher speed than manual packaging. Taking candy packaging as an example, manual workers can only pack more than ten candies per minute, while multi-head weigher packaging machines can handle hundreds to thousands of candies per minute, boosting productivity by dozens of times.
2. Reduced packaging cost and saved storage & logistics expenses. For bulky and fluffy products such as cotton, tobacco leaves, silk and hemp, the machine can work with compression units to greatly shrink package volume and cut packaging material costs. The reduced package size saves warehouse space, lowers storage costs and optimizes transportation.
3. Reduced labor intensity and improved working conditions. Manual packaging of large and heavy products consumes massive physical strength and brings safety risks. Multi-head weigher packaging machines solve this problem effectively.
4. Promote the development of related industries. Food packaging machinery is a comprehensive discipline covering materials, processing technology, mechanical equipment, electronics, electrical engineering and automatic control. Synchronized and coordinated development of all related disciplines is required. Technical defects in any discipline will affect the overall performance of the multi-head weigher packaging machine. Therefore, the advancement of multi-head weigher packaging machines strongly drives technical progress of related industries.
5. Protect operators’ occupational health. Manual packaging of dusty, toxic, irritating or radioactive materials inevitably causes harm to human health. Multi-head weigher packaging machines realize automatic operation to avoid such risks and protect the environment from contamination.
6. Guarantee consistent packaging quality. Mechanical packaging can produce packages with uniform specifications, shapes and sizes according to product requirements, which manual packaging cannot achieve. This is especially critical for export goods. Only automated mechanical packaging can meet packaging standardization and collective packaging requirements.
7. Enable special packaging operations impossible by hand. Special packaging processes such as vacuum packaging, gas-flush packaging, skin packaging and isobaric filling cannot be completed manually and can only be realized by automatic packaging machinery.
8. Ensure product hygiene compliance. Hygiene regulations prohibit direct manual packaging of food, pharmaceuticals and similar products to prevent contamination. Automated packaging eliminates direct human contact with food and medicine and maintains stable sanitary standards.
The above covers the working principle and core advantages of multi-head weigher packaging machines. Along with market evolution, multi-head weigher packaging machines keep upgrading to meet diversified production demands for more product varieties. The latest models adopt stepper motors with micro-stepping technology for high weighing precision. Equipped with a new real-time operating system, the machines feature stronger anti-interference performance, overcoming the drawbacks of conventional equipment. Continuous innovation keeps the machines aligned with market trends and delivers greater value for manufacturers.
