The invention relates to a board traction frame. The board traction frame comprises a front transverse plate, and a back transverse plate parallel to the front transverse plate; the left ends and the right ends of the front transverse plate and the back transverse plate are respectively connected with a left rotating plate and a right rotating plate in a hinge manner; groove parts are respectively arranged at the upper ends of the left rotating plate and the right rotating plate; longitudinal rods are transversely mounted in the groove parts; strip-shaped holes are vertically formed in the front and back two sides of the left rotating plate and the right rotating plate; and the front and back two ends of the longitudinal rods respectively penetrate through the corresponding side strip-shaped holes, and are respectively sleeved with connecting blocks. The board traction frame adopts the longitudinal rods with adjustable heights and adjustable rotating angles to match a traction wheel at the middle part by different gestures from two sides to form traction combination structures with different included angles so as to adapt to different traction friction force requirements, can reasonably pull tooth-shaped papers and plane papers with different hardness, materials and thicknesses, largely increases the equipment utilization rate, and prevents the equipment replacement.

The utility model relates to a producing facility plant directly using waste newspapers to produce corrugated boards. The utility model comprises the producing facility for raw paper, a producing facility compounding two layers, and a paperhanging producing facility for the corrugated boards, wherein, the producing facility for the raw paper is used for pastes a single piece of waste newspaper into a piece of long paper with needed specification; the double-layer composite producing facility is used for compounding two layers or more than two layers of long paper into a thick paper board; the paperhanging producing facility for the corrugated boards is used for processing composite waste newspaper boards into the corrugated boards, and then both faces of the corrugated boards are pasted with clear face paper to form the corrugated boards which are finished goods. The utility model can realize the recovery utilization of the waste newspaper without re-making paper procedure, and is environmental protection technology and equipment which have low energy consumption, low investment, low cost, high benefit but no pollution.
