QNGP-520LC Large Vertical Packaging Machine | Multi-Product Precision Weighing & Flexible Production

The QNGP-520LC large vertical packaging machine is a high-efficiency, intelligently upgraded packaging solution equipped with a professional multi-head combination scale. Tailored for automated industrial packaging, this granular food weighing and filling machine delivers precision metering for diverse products and highly flexible production capabilities, perfectly solving the annoying points of single-function equipment and unstable weighing accuracy for food and daily commodity manufacturers.

Boasting an ultra-wide application range, this all-round packaging machine supports the quantitative packaging of puffed food, nut granules, grains, mixed cereals, powder materials, hardware accessories and daily supplies. It breaks the limitation of traditional packaging equipment that can only process single-type materials, realizing one machine for multi-scene production. Whether it is solid granules, fine powder or irregular daily parts, the equipment maintains stable weighing and standardized packaging, greatly improving production flexibility and reducing equipment investment costs for enterprises.

At the core of its performance is the high-precision long-position multi-head combination scale. Made of premium stainless steel, the scale is fitted with high-sensitivity digital weighing sensors to ensure accurate and stable metering. It features automatic vibration amplitude tracking and intelligent adjustment, achieving uniform and smooth material feeding without blockage or uneven feeding. With a flexible measuring range of 150ml to 2000ml, it easily adapts to different packaging capacities, from small-batch refined packaging to large-capacity bulk packaging, with zero weighing deviation.

Equipped with an intelligent human-machine touch screen control system, the entire machine operation is simpler and more precise. Users can freely adjust all operating parameters and precisely regulate the working status of each component through the intuitive interface. The intelligent system supports real-time operation monitoring, ensuring stable and coordinated operation of every production link. The linked film pulling scroll design simplifies packaging film installation and replacement, saving setup time and improving overall production efficiency.

In terms of packaging quality and efficiency, the machine adopts a constant-temperature rotary end sealing and cutting structure. The thermal sealing cutter maintains stable temperature operation, realizing tight and neat sealing of product front and rear ends with smooth cutting edges and no material leakage. It supports a flexible packaging speed of 5 to 50 bags per minute, matching both low-speed refined production and high-volume mass production. The equipment adapts to multiple mainstream packaging materials including OPP/CPP, OPP/PE and PE/PET, with adjustable bag length (80–420mm) and bag width (50–250mm) to meet diverse packaging specification needs.

With a 2.5kw stable power output and robust integrated structure, this 550kg vertical packaging machine features sturdy construction, stable full-automatic feeding operation and low failure rate. Compact in overall size (1440*1216*1796mm), it saves workshop space while delivering long-lasting, high-efficiency production. Ideal for food processing and daily goods industries, it is a cost-effective intelligent packaging equipment to upgrade production lines.
