Import Cardboard Tube Making Machines — Buy in Bulk from Supplier in China

The convolute paper tube making machine from San Qingdao International Trade Co., Ltd. is an automated system designed for producing parallel paper tubes, primarily serving the metallurgy sector with secondary applications in clothing racks and pencil manufacturing. It integrates a paper stand, edge grinding and gluing devices with an automatic cycle system, a sprinkler setup, paper cutting and tube forming components, and a discharge mechanism. The machine employs a Panasonic servo motor for precise winding and mandrel positioning, alongside pneumatic cylinders to stabilise paper sheets before they enter the mandrel groove, ensuring smooth operation and minimal defects.

Constructed with industrial-grade components, the machine uses Siemens PLC for control and Delta Inverters for variable speed management, supporting a paper grammage range of 280 to 550gsm. It processes jumbo rolls up to 600mm in width and 1300mm in diameter, producing tubes with inner diameters between 16 and 50mm and wall thicknesses from 2.5 to 10mm. The system achieves a production speed of 600 to 700 pieces per hour, with a power demand of 9.4Kw at 380V, 50Hz. Typical applications in metallurgy include protective sleeves for coiled materials, while lighter tubes suit apparel and stationery industries.

Buyers in metallurgy and packaging sectors source this equipment for its reliability in producing consistent tube dimensions critical for industrial use. The machine’s design reduces material waste through precise edge alignment and automated gluing, making it suitable for high-volume production.
