         2 . The pipeline-type positive warp yarn feeding device as claimed in  claim 1 , wherein the yarn feeding frame is provided with a plurality of yarn feeding shafts, each yarn feeding shaft is provided with corresponding ones of the positive yarn feeding wheels, and the corresponding ones of the positive yarn feeding wheels are capable of rotating with the yarn feeding shaft. 
     
     
         3 . The pipeline-type positive warp yarn feeding device as claimed in  claim 2 , wherein a side of each positive yarn feeding wheel is provided with a wheel shaft clutch, and the wheel shaft clutch is configured to drive the positive yarn feeding wheel to rotate with a corresponding one of the plurality of yarn feeding shafts. 
     
     
         4 . The pipeline-type positive warp yarn feeding device as claimed in  claim 3 , wherein a key pin limiting component is disposed between each wheel shaft clutch and the corresponding one of the plurality of yarn feeding shafts, and the key pin limiting component is configured to restrict each wheel shaft clutch to only make axial displacement movements along the corresponding one of the plurality of yarn feeding shafts. 
     
     
         5 . The pipeline-type positive warp yarn feeding device as claimed in  claim 3 , wherein an inner ring bearing of each positive yarn feeding wheel is sleeved on the corresponding one of the plurality of yarn feeding shafts. 
     
     
         6 . The pipeline-type positive warp yarn feeding device as claimed in  claim 1 , wherein a yarn feeding positioning component is disposed between each positive yarn feeding wheel and a corresponding one of the yarn bobbins, the yarn feeding positioning component is disposed near a yarn entry end of the positive yarn feeding wheel and faces towards a winding travel starting end of the positive yarn feeding wheel, and the yarn passes through the yarn feeding positioning component from the winding travel starting end of the positive yarn feeding wheel to a winding travel ending end of the positive yarn feeding wheel. 
     
     
         7 . The pipeline-type positive warp yarn feeding device as claimed in  claim 1 , wherein yarn feeding pipes are disposed between the yarn bobbin frame and the yarn feeding frame, and the yarn feeding pipes extend from yarn outlet ends of the yarn bobbins to yarn entry ends of the positive yarn feeding wheels. 
     
     
         8 . The pipeline-type positive warp yarn feeding device as claimed in  claim 7 , wherein the yarn bobbin frame is disposed at a side of the yarn feeding frame, the yarn feeding pipes extend horizontally from the yarn outlet ends of the yarn bobbins to the side of the yarn feeding frame, and then vertically turn at horizontal positions corresponding to the positive yarn feeding wheels to extend to the yarn entry ends of the positive yarn feeding wheels. 
     
     
         9 . The pipeline-type positive warp yarn feeding device as claimed in  claim 8 , wherein a turning point of each yarn feeding pipe defines a ceramic yarn feeding eyelet. 
     
     
         10 . The pipeline-type positive warp yarn feeding device as claimed in  claim 6 , wherein a yarn outlet end of each positive yarn feeding wheel is provided with a yarn breakage automatic stopper, and the yarn breakage automatic stopper is disposed facing towards the winding travel ending end of the positive yarn feeding wheel.
