Rail type modular rotary knitting device based on rolling contact and rotary knitting machine

The invention discloses a rail type modular rotary knitting device based on rolling contact. Comprising a track groove formed by splicing an upper-layer plate and a lower-layer plate, and conical rolling wheels are installed on a yarn carrier base, so that it can be guaranteed that the yarn carrier smoothly rolls in the track groove. The driving gear combination drives the shifting teeth to push the yarn carrier to move. A detachable stop block is arranged on the outer side of the track groove, and the yarn carrier can be supplemented or detached along the track. The machine chassis of the continuous rotary knitting machine is modularized through the sectional upper and lower supporting plates, the conical rollers replace sliding shoes, and rolling friction replaces sliding friction between a yarn carrier of a traditional three-dimensional rotary knitting machine and a track, so that the motion fluency of the yarn carrier is greatly improved. 本发明公开了一种基于滚动接触的轨道式模块化旋转编织装置。包括由上层板、下层板拼接形成的轨道槽，载纱器底座安装有锥形滚轮，可保证载纱器在
