High Precision Multihead Weigher Packing Machine Combination Weighing And Packing Machine

Hot Selling High Precision QNGP-720GB Multi-Head Combination Weigher Packaging Machine | Precise & Flexible

The QNGP-720GB Multi-Head Combination Weigher Packaging Machine is a high-speed, high-precision vertical form-fill-seal machine specially engineered for pet food, grains, and a wide range of bulk granular products. Designed for modern automated production lines, this collar-type packaging machine stands out with its ultra-precise combination weighing and unmatched operational flexibility, allowing manufacturers to switch between diverse product types effortlessly while maintaining consistent packaging accuracy and stable output.

What sets this machine apart is its advanced fully automatic microcomputer combination scale system. Unlike traditional single-scale packaging equipment, it supports flexible combined weighing for granular, strip-shaped, round, and irregular materials. Whether for dry pet food, grain particles, and other bulk items, it achieves scientific matching and precise metering, effectively solving the weighing deviation problem of mixed and irregular materials. With a maximum measuring capacity of 4000ml, it adapts to diverse packaging capacity requirements, meeting small-batch and large-batch production needs perfectly.

Built with a standardized and efficient workflow, the machine realizes full-automatic one-stop packaging operations. It adopts a servo motor-driven film pulling device, with a multi-linkage film rolling shaft ensuring ultra-smooth film operation without jitter or deviation. The whole process covers automatic date coding, precise mold shaping, high-quality sealing, fixed-length cutting and finished product conveying. The optional finished product transport structure effectively prevents material accumulation, streamlining the entire production process and improving overall operational efficiency.

Offering outstanding production flexibility, the equipment supports multiple packaging materials including OPP, CPP, PE and PET. Its customizable sealing molds and replaceable sealing & cutting devices allow free adjustment of bag styles and cutting patterns according to production demands. Equipped with an optional gas flushing device for nitrogen, oxygen or air filling, it can extend product shelf life, fully catering to differentiated packaging needs for various pet food and grain products.

Driven by a stable 3kw frequency system, the machine delivers a high packaging speed of 50–55 bags per minute, balancing high efficiency and precise production. It features an adjustable bag length of 100–500mm and bag width of 180–350mm, with a 720mm maximum film width to support diversified packaging specifications. The ribbon coding device prints clear, fade-proof production dates, ensuring standardized product traceability.

Durability and safety are fully guaranteed. The entire machine body adopts premium 304 stainless steel material, featuring excellent corrosion resistance, rust proof, high temperature resistance and moisture resistance, suitable for long-term continuous operation in factory environments. With reliable structural design and stable operating performance, it reduces daily maintenance costs and downtime.

Ideal for pet food, grain processing and bulk material packaging industries, this combination weigher packaging machine integrates precision, flexibility and efficiency in one device, helping enterprises optimize production processes and upgrade packaging quality.

Workflow

1. Film running: Multi linkage film rolling axis pulling film, stable operation.

2. Coding: Date setting, automatic coding.

3. Bag making: Roll the film through a molding machine to determine the bag shape.

4. Cutting: After the sealing is completed, measure the cutting.

5. Sealing: A sealing mold with customizable punching effect.

6. Finished product transportation: This equipment can be added to avoid the accumulation of finished products.

Details:

1. Film pulling device: using servo motor, film pulling is smooth and runs smoothly.

2. Fully automatic microcomputer combination scale: used for various granular, strip, round, and irregular materials.

3. Automatic sealing and cutting device: Different sealing and cutting devices can be selected according to the bag style and cutting pattern.

4. The entire body is made of 304 stainless steel: corrosion-resistant, not easy to rust, high heat resistance, and good moisture resistance.

5. Printing date: The handwriting of the ribbon coding machine is clear and not easily faded.
