Import Automatic Cardboard Tubes — Buy in Bulk from Supplier in China

The SANPT16-76 automatic cardboard tube making machine from San Qingdao International Trade Co., Ltd. produces parallel convolute paper tubes with inner diameters between 16 and 76 mm and wall thicknesses from 2.5 to 10 mm. It processes paper rolls up to 1600 mm wide and 1300 mm in diameter, with a maximum tube length of 1200 mm and a production speed of 480 to 720 pieces per hour. The machine integrates a Panasonic servo motor for winding, a Siemens PLC, and a Delta inverter, ensuring stable operation and precise tube forming.

Built for industrial use, the machine accepts paper grammage from 180 to 300 gsm, typical for cardboard tubes used in metallurgy, clothing racks, and pencil manufacturing. Its design includes a paper edge grinding device, an automatic gluing system with a diaphragm pump, and a cylinder-based positioning mechanism to minimise defects. The 4.61 kW motor operates at 380V and 50Hz, with the entire unit measuring 1850x1780x1460 mm.
