The utility model relates to an interactive convex rail knitting machine, which comprises first guide rails, second guide rails, spindles, a dial plate and a platform surface, wherein the first and the second guide rails adopt crosswise horizontal 8-shaped structures, and are convex guide rails; connecting rails for ensuring the first and the second guide rails to be continuous and smooth are mounted at the crossed parts of the first and the second guide rails; the connecting rails have rotary and lifting motion forms, and are connected with a control mechanism; the spindles with rolling wheels are assembled on the first and the second guide rails; and the dial plate is mounted at the center of the horizontal 8-shaped structures. By adopting the interactive convex rail knitting machine provided by the utility model, seamless connection among the guide rails is ensured, not only can impact, frication and noise be effectively reduced, the work efficiency of the knitting machine is improved, but also the procedures for assembly and maintenance are simplified, and the manufacturing cost of the knitting machine is saved.
