1. The automatic packaging production line is a broad concept that can be classified into granular product packaging production line, powder product packaging production line, liquid product packaging production line, and sheet product packaging production line according to product form; According to the packaging method of the product, it can be divided into: post packaging production line for boxed products, post packaging production line for bagged products, post packaging production line for filled products, post packaging production line for barrel products, and post packaging production line for bottled products; According to the industry, it is divided into post packaging production lines in the food industry, beverage industry, pharmaceutical industry, daily necessities industry, dairy industry, and industries such as bio fertilizers, seeds, and feed additives.

2. The post packaging production line can be summarized into two types: cardboard box post packaging production line and large bag heavy bag packaging production line. Hualian Machinery Group is the only domestic group enterprise with independent research and development capabilities and the ability to independently design and manufacture all products for the back-end packaging production line.

The cardboard box automatic packaging production line is a new generation of automatic packaging production line that our factory has accumulated and extended over 30 years of experience in manufacturing packaging machinery. The entire line consists of a cardboard box unboxing machine, a boxing machine, a sealing machine, a bundling machine, a palletizing robot, a pallet warehouse and conveyor, a top bundling arrow type fully automatic bundling machine, and an online automatic wrapping film machine. In the entire cardboard packaging production line, adjustments can be made according to production requirements, such as adding anti-counterfeiting and anti smuggling software systems, material dust removal systems, weight selection or metal detection systems, unqualified product removal systems (unqualified intermediate packages (weight) are automatically removed to designated positions), automatic desiccant dispensing equipment, corner sealing machines, and other systems.

The large bag packaging production line is a new generation of automatic packaging line, which can achieve packaging automation in the production process of powder and granular raw materials, including weighing, feeding, picking, bagging, clamping, folding, sealing, batch number printing, inverted bag shaping, metal detection, weight re inspection, removal, conveying, robot palletizing, empty pallet distribution, actual pallet conveying, actual pallet top bundling, pallet winding, and actual pallet output. The large bag automatic packaging production line project can also be vividly described as the process from bag supply to truck engineering.
