Large jacquard axial direction unwinding device

The invention discloses a large jacquard axial direction unwinding device comprising a cylinder bobbin, a bobbin bay, round stop plates and a rotary yarn guide; two sides of the cylinder bobbin are respectively provided with the round stop plate; the two round stop plates and the cylinder bobbin are coaxially arranged; the surface area of the round stop plate is bigger than that of a side face of cylinder bobbin; the bobbin bay is arranged outside the cylinder stop plates; the rotary yarn guide used for unwinding warp yarns is arranged outside the cylinder bobbin. The cylinder bobbin in the prior art is slow in warp yarn unwinding speed, thus greatly affecting work efficiency; in addition, the cylinder bobbin leads out in a warp yarn tangent direction, so a radial unwinding mode can easily cause mutual winding of the warp yarns, so warp yarn high speed unwinding cannot be realized; the large jacquard axial direction unwinding device is simple in structure, convenient in usage, fast in unwinding speed, good in unwinding effect, and safer and more reliable in usage.
