spiral square paper tube machine - Welldoing trading limited
The Square Paper Core Making Machine is a fully automatic industrial processing equipment specially designed for mass manufacturing of high-precision square and rectangular kraft paper cores. Tailored for high-toughness kraft paper, recycled paper and coated kraft paper materials, this machine integrates the entire production process including automatic paper feeding, constant-temperature gluing, spiral multi-layer winding, precise square shaping, inline fixed-length cutting and finished product discharging. It perfectly upgrades the defects of traditional semi-automatic equipment, such as low output, irregular shaping, easy deformation and unstable bonding quality, becoming the preferred standardized production equipment for packaging, industrial manufacturing, building materials and stationery industries.
Different from ordinary round paper tube machines that cannot achieve precise square molding, this equipment adopts an exclusive integrated square mandrel and optimized spiral winding structure. The customized shaping design ensures standard 90-degree right angles, neat corners, flat tube walls and uniform wall thickness for all finished square paper cores. It effectively avoids common product problems such as corner warping, tube body bending and size deviation. Supported by a real-time tension control system, the machine maintains stable paper feeding during high-speed operation, ensuring consistent winding density and overall structural firmness. Capable of 24-hour continuous cyclic production, it greatly reduces manual intervention and labor costs while improving production uniformity and yield.
Equipped with a reliable Mitsubishi PLC intelligent control system and intuitive touch screen panel, the machine supports visualized and digital parameter adjustment. Operators can freely set and store production speed, winding layers, gluing volume and cutting length, realizing one-key specification switching and fast mold replacement. This flexible production mode meets diverse customization demands of different square core sizes. Meanwhile, the built-in intelligent monitoring system can automatically detect paper breakage, glue shortage and equipment jamming, triggering real-time fault alarms and safety protection shutdown to minimize material waste and equipment failure risks.
In terms of production quality and performance, the machine adopts an adjustable double-sided uniform gluing system. The precise constant-temperature gluing technology ensures even glue distribution and tight lamination between paper layers, effectively preventing degumming, cracking and delamination. The high-speed CNC cutting unit equipped with alloy saw blades delivers smooth and burr-free cutting sections, with a dimensional tolerance controlled within ±1.5mm, requiring no secondary trimming. The matched dust collection system absorbs cutting dust in real time, keeping the workshop clean and compliant with international environmental protection standards.
Adopting thickened carbon steel overall welding and professional anti-rust treatment, the machine body features strong vibration resistance, low operating noise and long service life. Supported by variable-frequency motor drive, the production speed is adjustable from 6m/min to 18m/min, balancing high output and energy saving. It stably produces square paper cores with a maximum side length of 100mm and a customizable length of up to 2500mm, covering most mainstream industrial specifications.
Manufactured eco-friendly and recyclable square paper cores are widely used for gift box lining, carton support, cable winding protection, building material packaging and craft tube production. With modular and integrated design, the equipment is easy to maintain with low daily operation costs. We provide complete after-sales services including professional installation guidance, systematic operation training, one-year warranty and lifelong technical support, ensuring long-term stable and high-efficiency production for global customers.
