The Grey Board Making Line is a fully automatic and intelligent industrial production equipment integrating raw material processing, composite forming, drying and shaping, precision cutting and stacking. It is professionally designed for the mass production of high-density and high-flatness industrial grey board. As the core production equipment in the fields of packaging and printing, hardcover book manufacturing, cultural and creative bag production, and industrial lining board processing, this production line adopts advanced dry-wet composite forming technology and intelligent control system. It effectively solves the common pain points of traditional grey board production, including unstable product quality, high energy consumption and heavy reliance on manual labor. With stable operating performance, flexible parameter adjustment and high-efficiency capacity output, it has become an essential core equipment for standardized and large-scale production in the board processing industry.
Adopting an integrated modular design, the entire grey board making line features a compact and reasonable structural layout, which does not require special foundation renovation. The equipment can be installed and commissioned on conventional flat cement ground, greatly reducing plant adaptation costs and installation cycles. The production line is equipped with complete core components, including paper loading and bearing mechanism, automatic paper splicing device, tension control system, composite bonding mechanism, compaction and shaping unit, constant-temperature drying system, cooling and flattening equipment, longitudinal slitting mechanism, computer transverse cutting unit, intelligent stacking equipment, as well as a complete set of electric and pneumatic control systems. All functional modules operate in synergy to realize one-stop continuous production from raw paper rolls to finished grey boards, requiring minimal manual intervention during the whole production process.
In terms of core technical configuration, this production line is equipped with a high-precision PLC intelligent control system, supporting digital parameter presetting and one-click start-stop operation. It can accurately control core production parameters such as production speed, board thickness, drying temperature and cutting dimensions, meeting the diversified production requirements of grey boards with different specifications and thicknesses. The built-in constant-temperature drying system features uniform heat distribution and adjustable temperature range, which ensures thorough and even drying of composite boards, effectively avoiding board deformation, warping and uneven hardness caused by inconsistent drying. Meanwhile, the independent tension control system maintains stable paper feeding tension throughout the production process, preventing paper deviation, wrinkling and fracture, and greatly improving the yield and qualification rate of finished products.

In addition to superior technical performance, the Grey Board Making Line has outstanding advantages in production efficiency and operational economy. The continuous automatic production mode realizes uninterrupted batch processing, greatly improving production efficiency and effectively reducing labor costs and manual operation errors. The optimized mechanical structure reduces equipment operation resistance and energy consumption, achieving energy-saving and environmentally friendly production. All key components adopt wear-resistant and high-strength materials, with stable operation and long service life, which lowers equipment failure rate and daily maintenance costs for enterprises.
Widely applicable in industrial production, the finished grey boards produced by this line are widely used in high-grade packaging boxes, hardcover books, gift boxes, handbag substrates, industrial backing boards and other scenarios. With stable board density, excellent flatness, good toughness and strong compression resistance, the finished products fully meet the high-standard quality requirements of downstream processing. Reliable in operation, flexible in adjustment and efficient in production, the Grey Board Making Line is an ideal professional equipment for medium and large board processing enterprises to upgrade production capacity and optimize product quality.
