Our Square Paper Core Making Machine is a professional fully automatic production device specially optimized for the manufacturing of high-precision square and rectangular paper cores. Different from traditional general-purpose round paper tube machines that have poor square forming effect and low finished product qualification rate, this equipment adopts exclusive customized square shaping technology and structural optimization design, focusing on solving the industry pain points of irregular right angles, uneven wall thickness, easy deformation and poor flatness of square paper cores. It realizes one-stop automatic production from paper unwinding, circulating gluing, multi-layer spiral winding, precise square shaping, fixed-length cutting to automatic discharging, greatly improving production standardization and efficiency for paper core processing enterprises.

Built with industrial heavy-duty structure, the whole machine adopts thickened integral steel frame and high-strength welding process, with surface anti-rust and anti-corrosion treatment, which ensures stable operation for a long time and effectively reduces vibration and running noise during high-speed production. The core forming part uses a high-precision integral square mandrel and balanced pressure shaping mechanism. With matching constant tension control system, the equipment can always maintain uniform paper feeding tension in continuous operation, effectively avoid paper deviation, loose winding and core distortion, and ensure that all finished square paper cores feature standard 90° right angles, flat and smooth tube walls and consistent overall size.

In terms of intelligent operation, the machine is equipped with mature PLC programmable control system and humanized touch screen operation panel. All key production parameters such as winding layers, processing speed, glue coating volume and cutting length can be adjusted digitally and stored in the system. Users can switch different production specifications with one click, realizing rapid conversion of square cores of different sizes and meeting the production needs of diversified and customized products. In addition, the built-in intelligent fault self-inspection function can real-time monitor abnormal conditions such as paper breakage, glue blockage and equipment overload. It will automatically alarm and stop for protection, which avoids equipment damage and material waste, and improves production safety and stability.
This equipment adopts adjustable uniform gluing technology, which supports single-sided and double-sided gluing according to production demands. The glue amount is evenly controlled without overflow or missing coating, ensuring tight bonding between paper layers. The finished square paper cores have high compression resistance, strong toughness, no delamination and no degumming, with excellent structural stability. Equipped with high-precision alloy cutting blades, the cutting section is smooth and burr-free with ultra-small dimensional tolerance, no secondary finishing is required. The matched dust removal device keeps the production environment clean and tidy, fully complying with modern industrial environmental protection standards.

The machine has strong material adaptability and specification flexibility, compatible with kraft paper, recycled paper, coated paper and composite paper materials. It can stably produce various square and rectangular paper cores for industrial and packaging use, widely applied in gift box support, carton reinforcement, cosmetic packaging, food packaging, cable winding protection, hardware accessory packaging and craft paper core production. Adopting modular assembly design, the equipment has a simple internal structure, convenient daily maintenance and low operating cost. We provide complete after-sales service including installation guidance, operational training, one-year quality warranty and lifelong technical support, helping global customers achieve stable, efficient and high-benefit paper core production.
