Lifting system for inner yarn rails

A lifting system for inner yarn rails, comprising an in-air conveying rail (3), said in-air conveying rail (3) being configured to convey a carrier assembly (5), and said carrier assembly (5) being configured to carry a winding package (10);

• wherein an inner yarn-rail-lifting section (31) is arranged on said in-air conveying rail (3), the inner yarn-rail-lifting section (31) is positioned on both sides of a twisting machine (1);
• when the inner yarn-rail-lifting section (31) ascends, it communicates with said in-air conveying rail (3);
• when the inner yarn-rail-lifting section (31) descends, it approaches a position of a spindle bucket (4) of the twisting machine (1),
• wherein a supporting frame (201) is arranged on the both sides of the twisting machine (1), a lifting rail (211) is vertically arranged on a stick (214) of said supporting frame (201), a lifting pulley assembly (212) is arranged inside the lifting rail (211), and the lifting pulley assembly (212) is connected with the inner yarn-rail-lifting section (31) by means of a connecting rod (208);
• the supporting frame (201) is provided with a plurality of rotary rotation shafts (202), which are arranged in a direction parallel to the inner yarn-rail-lifting section (31), and the rotation shafts (202) are connected to a driving device (215) to drive the rotation shaft (202) to rotate, a plurality of winding disks (203) are arranged on the rotation shaft (202), each winding disk (203) is wound with a suspending belt (206), the lower end of the suspending belt (206) is connected to the inner yarn-rail-lifting section (31), and the rotation shaft (202) rotates to drive the inner yarn-rail-lifting section (31) to ascend and descend,
• wherein at a position where said in-air conveying rail (3) is connected with the inner yarn-rail-lifting section (31), said in-air conveying rail (3) has an upper baffle (209) arranged on atop of its-end head, and side baffles (210) arranged on its both sides, the upper baffle (209) and the side baffle (210) are beyond the end head of said in-air conveying rail (3), and an inside of a bottom of the side baffle (210) is provided with a bevel (217), which is thinner in thickness at a bottom portion, and thicker in the thickness at a top portion.
