Shanghai ENJUE Machinery Equipment Co., Ltd is one of the most experienced manufacturers and suppliers of double-line bagging and weighing machine in China. If you're going to buy custom double-line bagging and weighing machine made in China, welcome to get more information from our factory. For price consultation, contact us.
The ENJUE double-line bagging and weighing machine is a high-efficiency, heavy-duty quantitative packaging equipment designed specifically for ports, grain trunk lines, and bulk cargo logistics. The container utilizes advanced continuous feeding and weighing control technology, integrates a reinforced steel structure and Pakistani transportation systems, and enables automated operations from bulk materials to standard packaging bags, significantly improving the efficiency and accuracy of terminal transshipment and export cargo operations.
The core design feature of the port double-line bagging machine is a large hopper capacity, compatible with belt conveyor feeding, ensuring continuous and uninterrupted material supply. The combination of dual-stage (fast and slow) feeding and high-precision sensors guarantees rapid and accurate filling of each 50 kg bag. The entire machine is manufactured according to heavy industry standards, with rigorous welding and assembly processes, ensuring long-term stable operation in harsh port environments such as dust and humidity.

Core Structure and Design Features of The Port Double-line Bagging and Weighing Machine:
Large-Capacity Hopper: The 20-cubic-meter hopper effectively buffers the material flow from the upstream conveyor belt, ensuring continuous packaging operations and reducing the impact of upstream supply fluctuations on packaging accuracy.
High-Speed, High-Precision Weighing System: Employing a servo- or pneumatically controlled dual-speed feeding device (coarse and fine flow), combined with high-resolution weighing sensors and an intelligent controller, this system ensures high-speed filling of over 1400 bags per hour while maintaining the weight error of each bag within industry-leading standards.
Heavy-duty belt conveyor integration: The double-line port bagging and weighing machine integrates or seamlessly connects to a heavy-duty belt conveyor at the bottom, smoothly transporting filled bags to the sewing machine or subsequent finishing stations, forming a smooth packaging production line.
Industrial-grade structural design: The entire machine weighs 22 tons. The main steel structure uses high-quality steel and strictly adheres to ISO welding and manufacturing tolerance standards to ensure the rigidity and durability of the equipment under heavy loads and continuous operation.

Applications of the double-line bagging and weighing machine
Port terminals: Export packaging of bulk cargo such as grains (wheat, corn, soybeans), feed, fertilizers, and plastic granules.
Large-scale grain logistics bases and storage facilities.
Packaging of bulk products in industries such as chemicals and building materials.
Any logistics环节 requiring the conversion of bulk materials into standard bagged products.
