What is an automatic steel pipe packing machine

The automatic steel pipe packaging machine is an automated mechanical device specifically designed for bundling steel pipes. Its core function is to entwine, tighten, and weld steel pipes with packaging belts (such as plastic belts and steel belts) to ensure secure and reliable bundling, meeting transportation and storage needs. The following provides a detailed introduction from four aspects: technical features, application scenarios, advantages, and selection recommendations:

1. Technical Features
High degree of automation
Equipped with a PLC control system, it supports photoelectric sensing or intelligent program control, enabling automatic completion of the entire process including tape feeding, tightening, welding, and tape cutting, reducing manual intervention.
Some models are equipped with multi-channel strapping function, which can simultaneously wrap steel pipes multiple times to enhance strapping stability.
Efficient bundling
The strapping speed is typically ≤2.5 seconds per pass, which is much faster than manual packers and suitable for large-scale production scenarios.
Support continuous operation. The motor automatically enters standby mode after 60 seconds of inactivity, saving energy and reducing power consumption.
structural optimization
High-strength blades (such as alloy steel with a hardness of 65) and resin casters are used to enhance the cutting ability and mechanical mobility.
With an aluminum alloy frame and a modular shell design, the size of the bracket can be adjusted according to the size of the steel pipe, accommodating packaging needs of different specifications.
Safety and durability
Equipped with an automatic shutdown device and a braking system (such as a disc brake + spring design), it ensures smooth and noiseless belt feeding while preventing mechanical overload.
Key components (such as circuit boards and heating plates) are designed with modularity, facilitating maintenance and replacement.
II. Application Scenarios
Steel pipe production and processing
Suitable for bundling long strip metal materials such as seamless steel pipes, welded steel pipes, threaded steel pipes, etc., meeting national standards (e.g., single bundle weight of 5 tons, length of 6-15 meters).
It can be integrated with processes such as steel pipe cutting, stacking, and weighing, achieving automated integration of the production line.
Logistics and warehousing
Ensure that steel pipes do not scatter during transportation to reduce the risk of cargo damage.
Tidy and aesthetically pleasing bundling improves the utilization rate of storage space.
Other industry extensions
Similar technology can be applied to the bundling needs of industries such as plastic straws, waste paper recycling, food, and medicine, but the material and parameters of the strapping need to be adjusted according to the characteristics of the material.
III. Comparison of Advantages
Features: Steel Pipe Automatic Packaging Machine, Manual Packaging Machine
Efficiency: High-speed automation, suitable for large-scale production. Reliance on manual labor, slow speed
Strapping Strength: High-strength packing tape combined with hot-melt connection, ensuring firmness and reliability. Mechanical fasteners or simple winding, prone to loosening
Applicability: Suitable for heavy, elongated materials; suitable for light, round or irregular materials
Cost: High initial investment, but low long-term operating costs; Low equipment cost, but high labor cost
Maintenance: Modular design, easy to maintain; simple structure, but prone to wear and tear
IV. Selection Suggestions
Select based on steel pipe specifications
Round tube: Choose a model with adjustable bow frame, such as the universal type for Φ20mm-Φ355mm.
Square and rectangular tubes: Priority is given to models with multiple strapping and adjustable pulleys.
Cold-formed steel: It is necessary to confirm whether the equipment supports the bundling of irregular cross-sections.
Focus on core parameters
Tensile strength: For heavy-duty steel pipes, it is necessary to choose a machine with a tensile strength of ≥850 kilograms.
Bandwidth and thickness: The conventional bandwidth ranges from 19 to 32mm, with a thickness of 0.8 to 1.2mm, which needs to match the size of the steel pipe.
Power supply and air pressure: Industrial-grade equipment typically operates on a 380V/50Hz power supply, while pneumatic models require an air pressure of 0.5-0.7MPa.
